Leather car steering wheel and shift boot/knob

Picture of Leather car steering wheel and shift boot/knob
Given that I drove the same car for over 10 years, certain parts are getting a little worn around the edges. For instance, my shift boot is a piece of vinyl. It's been coming apart at the seams and started to get annoyingly stiff up around the neck. I've started to look for replacement leather shift boots, and as expected found tons of them all over the Internet. I picked out ones that specifically claimed to fit my car, but then it occurred to me that it may not fit right. I don't use the OEM shift knob and the original boot never cinched at the neck right for my shift knob anyway. So a pre-made shift boot may fit well to not too good ugly. Given that most likely, I'll need to modify ones that are premade, why not just sew one together myself. Just need to cut and stick together 4 pieces of material. How hard could it be?

Well, that single question to myself started this whole leather thing, and I eventually ended up with a leather wrapped shift knob and steering wheel in addition to the original project, the shift boot. I have never thought about a leather steering wheel, and my plastic wheel was just fine, however most cars today at least have leather as an option for the steering wheel. So figure why the hell not.

Unfortunately, I didn't take any pictures while doing the boot and shift knob, but those where easy compared to putting together the steering wheel.

Step 1: Practice, practice, practice

It is generally a good idea to practice on a couple pieces of leather scraps prior to cutting and working with the actual pieces that are to be used. If using a sewing machine, definitely test out the stitching and note how's the tension, consistency of the stitching patterns, signs of skipping, etc. I've read most household sewing machines will handle leather, but that doesn't mean that it will be trouble free and work as good as heavy industrial machines. Found out that the one we have lying around the house worked for the most part, however the leather doesn't advance well because it's soft. Taping a piece of tracing paper or wax paper on both sides took care of that issue. Using leather machine needle also turned out to be a must. Heavy duty or jeans needles didn't make even stitching on this machine.

Leather is a natural material, therefore its firmest, thickness, and tendencies to stretch varies even within the same piece of hide. Picking carefully and arranging the pieces to be cut will result with better results than trying to randomly group the pieces.

This project took a fair amount of time because of the work involve. Professional custom leather upholsters aren't cheap because of this and, the material isn't a bargain either. However, this is my absolute first time working with this material so with patience, times, good old trial and error it is possible to end up with good results.

Okay then, with that said, here we go.


Materials needed:

Upholstery grade leather,
Chalk,
Sewing machine,
Leather sewing machine needle,
Hand sticking needle(s),
Nylon or polyester sewing thread,
Box cutter blades, x-acto knives, or rotary knife (highly recommended for cutting leather)
Skiving knife
Double stick tape/contact cement,
Wax or tracing paper,
And lots of time.

Step 2: Removing and preping the steering wheel

Picture of Removing and preping the steering wheel
First step is to remove the steering wheel, this makes it a lot easier to work on. Since there are numerous articles on how to remove the steering wheel floating on the web and auto forums, we'll get into the next step.

Definitely us caution when taking off an airbag equipt steering wheel. Things can happen, bad kind things. I took the precaution and even touched exterior door panel incase there was static electricity. My car has a red connector conveniently stored by the airbag disconnect. This red connector shorts out the contacts to the airbag and reduces the chance of an accidental discharge.

Step 3: Cut and piecing together the leather

Picture of Cut and piecing together the leather

IMG_1616_1.JPG
Paper was used to get patterns for the basic shapes needed. The paper pattern is used as a guide only. The paper will not stretch and give the way the leather will, therefore the final leather pieces need to be slightly smaller to get a tight and snug fit. For example, the wide of the leather was reduced by 1/4" as compared to the total diameter of the steering wheel. I just used chalk to outline the leather just like in any school project.

This particular wrap was done in 4 separate pieces. I barely had enough leather to work with so I had to settle and included defects in the hide and combined slightly different texture. If I had a bigger piece or more pieces of leather, I could have been a little more selective.

Step 4: Skiving the Seams

Picture of Skiving the Seams
IMG_1641_1.JPG
IMG_1626_5.JPG
IMG_1627_6.JPG
Now that I've cut out all the pieces I need, I clipped all 4 pieces together and placed it around the wheel to see how it fitted. With the test fit appearing to be good, the ends needed to be shaved down. Once the stitches are sewn together, this will allow the overlaps to sit flush with the thickness of the adjacent leather. The better this is done, the smoother the outside top of the leather will be. Skiving knives could be found is certain craft supply store or ordered through the Internet. I just bent a piece of bracket I had lying around. It's simple a box cutter blade held on by a screw on one side and a clip with the handle on one side bent back. A couple pieces of index stock paper are used to space the blade from the bracket. I've practice on a couple pieces just to get a feel of what it was like. While doing the actual pieces, I took my time peeling little by little. If I cut though, there's no going back. Cutting leather this way appears to dull the knife really fast. However, my setup uses cheap box cutter blade, so not a big deal.

After skiving the leather ends on all seams to be joined, the next step is to permanently sew and glue them together end to end then flatten with a roller or a plastic credit card will do.

Step 5: A little addition

Picture of A little addition
IMG_1631_5.JPG
IMG_1609_10.JPG
Since I'm at it, I also decided to modify the steering wheel slightly. I include thumb rests at the 2 and 10 o'clock positions. These were shaped from a rather thick pair of ladies flip flop. As I shaped these, I realize these were the same material and density as craft foam. Could have glued together a couple of layers I had laying around and ended up with the same results. I only considered the flip flops because I thought it was a denser and stiffer material then craft foam, but it was the same thing. It took a little work to get two pieces relatively symmetrical. Simple just kept sanding until I was happy with the shape. I actually installed the one at the 10 o'clock position for a week prior just to see if it was something I wanted to go with. It turned out to be comfortable so it made it in the project and got glued on. Additional thoughts were spent figuring out where I wanted the stitching to end up along the rests and the corners directly below. The seam was planned so it ended up on the outside of where I'll usually grip the wheel. Directly below the rest is where I tend to power spin the wheel with my index finger when parking. Here, I kicked the seam towards the back of the wheel to keep it away from rubbing off my skin on my finger.

Step 6: Preparing the Leather Peice

IMG_1629_7.JPG

IMG_1633_3.JPG
With all the 4 pieces sewn together, the entire length is about 1 inch less the outside diameter of the wheel, this stretched the outside of the leather for a nice snug fit. The objective is to stretch the outside radius so the inside radius do not need to be gathered as much. If there is too much material on the inside radius, it may cause loose and crinkly waves.

To get the leather to stay on the wheel, I decided to use an euro stitching pattern. I think it looks more interesting and will keep the leather on the wheel tighter than the standard baseball stitching. The bad part is that it takes more steps and longer to do. In order to do this type of stitching, a running stitch needs to be sewn on both edges for the leather seam. The spacing I used for the running stitching was about 6 stitches per inch place 1/8" from the outside edge of the seam. These stitching will be used to bring the two sides together in the next step.

Step 7: Stiching on the leather piece

Picture of Stiching on the leather piece
Now, to actually stick the leather on the steering wheel. To give me a free hand, I mounted a quick-grip clamp to the desk and tied a socket wrench with a 6" extension bar to the side of the clamp. this allowed the steering wheel to turn and stay upright by itself freeing both my hands to do things.

To bring the two sides together, it's simple going around the stitching placed by the sewing machine. The hand stitching is simply a spiral weave between the two running stitches. After the first pass, I went back with a hook to tighten and space the tread. To visualize the pattern, it can be found on the wires pattern of a chain linked fence. It's the same concept and creates the same pattern. Note, there's a continuous piece of clear double stick tape running the whole outside circumference and a couple of pieces on the inside to keep the leather wrap from twisting during use.

Step 8: Finishing touches

Picture of Finishing touches
IMG_1638_1.JPG
To finish off the ends of the spoke, it was simply apply contact cement to the leather and the corresponding part of the steering wheel, wait until both sides are tacky and press together. Due to the horn buttons on this particular car, the buttons needed to be set into the leather. I initially thought this would be an issue and may possibly need to shave the steering wheel openings with a dremel to get the horn buttons to go back in. Also, the airbag sits flush to steering wheel spokes, thought I'll need to shave the sides of the spokes as well since there is absolutely no play in between. After all was done, I was pleasantly surprised the material of the steering wheel gave enough so the horn buttons and the airbag squeezed in for a nice fit. I've waited to cut the holes and excess leather at certain areas because I really wasn't sure where some parts of the piece was going to end up. An "X" was carefully cut out in the middle of the hole. Before gluing the piece down, I picked at the overlaps with a nail cutter to thin out the leather here. since the flaps will not be visible, it didn't matter that this was a little sloppy, The skiving knife would be too difficult to use with the piece partially on the wheel already.

With the leather wrap completely installed and all ends of the treads pulled tight and terminated, the only thing to do was to install the wheel back on the car and enjoy.

Step 9: Final thoughts

Picture of Final thoughts
IMG_1675_3.JPG
IMG_1678_1.JPG
IMG_1681_2.JPG
IMG_1676_4.JPG
As you can see, in terms of looks, barely any noticeable difference from the stock finish, (except the thumb rests). However, compared to the bare molded rubber finish, the leather definitely feels richer and provides a slightly better grip. I wrapped it pretty tight so the firmness is practically the same. There are different colors, textures, and even perforated leather to choose from, I imagine the combination of possibilities are endless if someone decides to go a bit more colorful or wild. For me, I just went down to a local auto upholstery shop and the owner sold me two sheets of plain black leather scraps. I paid him $20. All together, treads, needles, and misc items were another $10 at most.

The shift boot turned out perfect. The texture on all sides are even, the thickness and softness are consistent, even the creases in the neutral position ended up symmetrical looking on both sides. The shift knob is a billet aluminum Razo. Decided to wrap it since it is scratched up from over all these years of use. The only thing I didn't like about the Razo is that it gets scorching hot when it's in direct sun for a little. Wrapping it in leather solved that problem. The top sticks took a little extra planning since it needed to correspond to the sticking on the sides. Anyway, the shift knob turned out as expected, leather is tight to the knob, and the shift boot is exactly the right size transition at the neck of the knob. The steering wheel, unlike the other items, didn't turn out so perfect. Since I was tight on material the spoke by the horn actually fell a lillte short. This is irritating after all that work. Also since I had to settle on using different quality of leather, certain parts didn't stretch as much as the rest, this caused the left thumb rest to deform a little. All in all, it took me a 3 day weekend to do the steering wheel. It took a good amount of time, but considering this is my first experience working with the leather, learning how to use a sewing machine, shaping a pair of thumb rest from a pair of flip flops, I actually got a lot done.

Hope this process I've been though maybe of use in some way to those thinking about trying to work with leather.

Hi Cohn! Great tutorial and awesome result! I need to ask you a question, i made my design in four pieces, and as you i made the cuts, where a piece meets the other piece, round, to make the inner shorter than the outer side of the design. But i need your help in knowing how much shorter should it be.

Thanks!

Chris

I think I wrapped a scrap piece of leather around a part of the steering wheel and tied a string around it. Then tugged on the leather until I was happy with how it sat and marked where the string intersected the leather. Think this should give you the cut you need no matter the size of the wheel or the consistency of the leather.

this is great instructable thanks for sharing

nhickey1 year ago
Hi Cohn.. This instructable made me sign up to say what an awesome job you did! I'm going to give it a go on my Hilux. I'm guessing it's essential to take the steering wheel off, would I be right?.. I'd probably prefer not to if I can help it. Excellent job tho!
COHN (author)  nhickey1 year ago

Not sure if you tried doing it yet, but I would say you can do it while leaving the steering wheel on, but it's definitely easier to position the wheel then to position yourself while sewing the wrap on.

Sarek4 years ago
Awesome write up! I currently have an S2k that I was going to send out the wheel and knob to get custom red and black leather to match my door panels. I'm now contemplating doing it myself!

I'm very grateful to have found this instructable. How has the stitch held up these past few yrs?

Thanks again for the drawing, that made things much clearer and easy to understand. I've already copied into my pic file (if you didn't mind).

Great job. I'm going to go practice sewing now :D

COHN (author)  Sarek4 years ago
Hey, I’m glad people have found this process useful.

Because I used a regular sewing machine, I could only use “heavy duty” upholstery sewing machine thread, which is not the same as actual upholstery thread. It’s not as thick and therefore, probably not as strong. However, because it’s thinner, it actually sits into the leather more. Plus the inside of the wheel probably don't get as much wear as the outside.

I’m happy to report that there’s no fraying or problems with the stitching since finishing the wrap.

Good Luck if you're going to try it.
I have a suggestion for another thread that might be better in the long-term. While upholstery thread is great for many applications, I would recommend using a UV thread for long-term durability if it will be exposed to frequent sunlight. It is a step up, offering more protection against UV rays, and should last quite a bit longer before sun rot becomes an issue. It's used in outdoor applications such as tents, boat covers, sails, and awnings. You can find it in a variety of weights, some of which will work nicely with a normal sewing machine, and some meant for a heavier machine. It is a more expensive thread, but may well be worth the investment, so your stitching doesn't deteriorate before it's time.
COHN (author)  Jamie Marie1 year ago
That's interesting, I've not aware of these threads. I was only able to find black nylon at a local fabric shop. What kind of store sells these? I was trying to find heavier weight furniture upholstery thread but only saw it online. Didn't want to order something that might not work with a regular sewing machine. I even had issues finding a leather sewing machine needles. Actually the blue thread is for wrapping guides on fishing poles so have no concerns with it discoloring nor has it, but it can't be used on the sewing machine. It would untwist from the friction while pulling through the leather, stitching by hand was okay.
You can get the UV thread from a company called Sailrite, as well as standard size leather needles. (A lot of places sell the thread besides this one company, but they've got good info on their site to help you decide what you need.) They have info on each of their thread descriptions about what size needle should be used with it, as well as fabric weights, so you should be able to determine if you can use it on your machine. I don't have first-hand experience in this area, as I use my industrial machine for leather, rather than one of my standard ones.

I hadn't considered discoloration of the thread when I suggested this thread, though that would be important. What I was thinking of was the strength and integrity of the thread over time. For someone who parks in a garage most of the time, I shouldn't think it would matter too much, but if the car is sitting in the sun much, it might be worth spending a bit more on the thread, so all the hard work put into it will last longer.

Thanks for the update, I will also be using a regular sewing machine for the project. I'll let you know when I get a chance to finish. Thanks again for posting!

I know this is old news, but I would just like to say thanks. Your finished product looks awesome. I am a civic man myself, but Preludes are cool too. I actually like your body style better than the later ones....

wow very nice i was wondering were do you buy raw leather
It's amazing what a fine job you did on your first attempt.
Bravo.

I wonder how a callous plane might work for the skiving,
COHN (author)  Closer4 years ago
That's a good idea, it just needs to be sharp. I noticed that the softer the leather, the sharper the knife has to be.
Closer COHN4 years ago
Yes. The thing I am thinking of may be better know as a corn plane. The blades it uses are minature razor blades so they are very sharp.
COHN (author)  Closer4 years ago
Sounds like it should work fine. If you do get around to trying it, let us know how it goes.
PITKINH4 years ago
If you use fabric to make the pattern, instead of paper, it will be more exact.

Excellent!  Thank you for the time and effort to put this up.  Especially for the illustration on the final stitching.  I'm working on walker and cane handle covers and this helps beyound measure!  Thank you.

By the way, this is the only comment I have ever made in the many years as an Instructable viewer.
jmt31288!6 years ago
all i have to say is wow dude..... wow. i need to know how did you stitch the leather again?
COHN (author)  jmt31288!6 years ago
Sorry, should have actually took a video of this, it is kindda hard to describe. I'm attaching a higher res pict of step 7, it's a little clearer. Let me know how this work out.

no i think a vid would work better cause i tried it and i am confused by it
COHN (author)  jmt31288!5 years ago
I didn't know that my picture would get resampled, otherwise you would have been able to zoom in to see the details. Anyway, did a sketch that should clear things up. Have you already used a sewing machine to put a row of stitching on both sides of the seams?

This picture makes everything clear! thanks ;) 
jmt31288! COHN5 years ago
OHHHHHHH so you needle thread on eather side like over under, then you thread between the thread that you threaded over and under between the over thread. so the thread that is outside the leather connects the two threads like a chain linked fence.

If this is your first leather wrap job, you have been quite successful. The finished wheel looks great. I am an automotive interior designer and I have seen less professional pieces come out of production studios. What experience do you have that helped you pattern the leather?
COHN (author)  whiteoakart5 years ago
Thanks for the complement. I was actually a little bummed it didn’t turned out perfect. Now that you mentioned other works you’ve seen, it kindda hit me that it could have turned out a lot worst. I’ve used a sewing machine once before. I made this reinforced slip holder for an expensive camera lens filter. That probably help, other than that, I just took a practice run with scraps in each step before doing the final piece(s). During the whole process, I knew the leather needed to be tight on the wheel. Driving would be annoying if the leather slips and slides. Sounds like you have a fun job, you work for a shop or a car company?
I work for a small engineering firm, Griswold Engineering.  We contract out to car companies and other manufacturers.  It is a pretty fun job.

How did you know to use this particular stitch on the steering wheel?  I am amazed you were able to pull this off so well.  You must have a very good sense of how things are made.  I know you are new to Instructables.  Do you make a lot  of things by hand?

COHN (author)  whiteoakart5 years ago
Sounds like you have a job that some would kill for.  I’m an architect by trade, suppose I’m a tinkerer during my free time.  I do have and use a bunch of stuff I’ve made, unfortunately have even a bigger bunch of stuff that is half made.  I’ve been looking to get into electronics and welding perhaps one day and Instructables is just an awesome place to find peoples sharing project like these and then some.

Did some research, actually was trying to find the way MOMO did their butt seam, with no visible stitches. No luck, so I’ve settled on the weave. I suspect they just glue it, but didn't trust my gluing to hold up.  I actually came across an article on autospeed.com a long time ago showing a pro re-leathering a wheel using this stitch. Then I worked backwards and figured out the steps needed to achieve the weave.

Very Nice Job! I have been thinking of what to do with the cracked and rather shoddy steering wheel on the 1965 Austin Healy Sprite that is my never ending project car - now I know how to recover it in style. Thanks.
I like how you added something in there like the thumb rests, not really for me, but something custom.
Jiffilude6 years ago
yeah its pretty pricy to put a s2k on it and they run upwards of 250. but right now im redoing the crappy center console that came with mine (its a 93) so you might see an instructable for it in the coming month P.S. the guys on preludeonline would love this, i dont think there has ever been a thread about redoing the stock wheel, there has been one about someone who will do it for $$ but not a DIY one.
COHN (author)  Jiffilude5 years ago
Look forward to see how your console comes out, hope it turns out spiffy. Maybe I'll throw a thread in that group, not sure on how many will actually do this, kindda tedious, at least the way I’ve done it. By wrapping the whole wheel, except the airbag, probably took twice the planning and time as just doing the wheel by itself. To me, it wouldn’t look as good otherwise.
Jiffilude6 years ago
wow that looks amazing, nice car by the way; i love my prelude. maybe with a little practice i will try this
COHN (author)  Jiffilude6 years ago
Nice to see a fellow luder on this site. I was planning to post this on a prelude forum, but I never got an activation message from that site. There's a bunch of luders out there (esp. 4th gen) that wants a better steering wheel, but don't what to give up the airbag. From what I can find out, only one from an S2000 fits. I even had a momo wheel at one time. Felt good, but no airbag, cruise, or even horns( unless I cut and splice the wire harness).
