Introduction: Pallet Pry Bar 2.0 - No Welding!

Picture of Pallet Pry Bar 2.0 - No Welding!

I must give 100% credit for this idea to instructables user darren8306. He is the original inventor of the concept and has a great instructable on a welded version. While I run a shop and have access to an array of welding and machining equipment I know a lot of people don't. When talking with one of my good friends about the tool he asked me to make one for him. I decided that I would come up with an easy to make version of the tool that required no welding and used basic hand tools to create. This way I could make him a pallet pry bar while also helping others out there make their own without a welder.

The only tools used in this process are an angle grinder, drill, hammer, center punch, and square. If you have access to a drill press this makes everything more precise and a lot easier. While there are a lot of tools in my shop that would have made this process easier for me I used only hand tools to prove it could be done. Let's get started!

Step 1: Step 1: Cut Out the Business End

Picture of Step 1: Cut Out the Business End

You will need to find some steel. I am using a scrap piece of 1/4" plate. You may be able to get away with using 3/16" plate, but I wouldn't go any thinner. The dimensions of the claw is 4" tall x 5" wide. The upright portion of the L is 1-1/4" wide and the bottom part is 1-3/4" wide. I have added captions to the first image with dimensions.

Mark out your shape using chalk, sharpie, or a scratch awl. Put on those safety glasses and ear muffs, you will need them. Using an angle grinder with a cut off wheel cut out the shape you just marked out. I recommend wearing a dust mask while grinding if you don't want black snot for the day. They key to getting accurate cuts with the cutoff wheel is to maintain a firm steady grip on the grinder. Don't let it jump around on you and you will get cleaner cuts as well as use less cutoff wheels. I completed all of my cutting with only one partially used disc. If you are new to the angle grinder I recommend picking up 4 or 5 discs, you may need the extras till you get the hang of it.

If your piece is still attached in the corner where you couldn't cut all the way through give it a whack with your hammer to knock it loose. Be careful! the piece you just cut is really hot so don't pick it up with your bare hands! You just used friction to burn away an 1/8" wide section of your material. To cool off your piece you could dunk it in water, but this will cause your material to become brittle from rapid cooling. Just be patient, if you want to hurry the process a little, place a heavy metal object on top of it to act as a heat sink.

Once cool enough to touch place the 'L' you just cut on top of the 1/4" material and trace it. Cut out another claw the same way as the first. Try to get these as close to identical as possible, this will make your job easier on the next step.

Step 2: Step 2: Final Grind

Put the two pieces together and clamp in a bench vise. Line them up as close as possible. If you were precise with the cutting wheel your two claws should be very similar. Using the angle grinder with a standard grinding wheel grind down all of the sides. This will ensure that your two pieces are identical. You will want to grind until the grinder has left marks across the surface on both pieces and they appear even. Clamp the claws using a C-clamp then flip them over to grind the bottom. Clamping the claws together before flipping them prevents them from getting misaligned when you loosen the vise. I rounded over the corners using the grinder just to make things a little softer.

Step 3: Step 3: Drilling Holes

Picture of Step 3: Drilling Holes

Measure and mark the center of one claw. Using the center punch and a hammer create a divot for the drill bit to start in. This will prevent the drill bit from wandering as you are starting the hole. Line everything up and clamp it in the bench vise again. Drill the two holes through both pieces using a 5/16" drill bit. Since your pieces were aligned and clamped together both sides should be identical.

Using one of the claws mark where the holes go on a piece of pipe. I used 1" sch40 steel pipe. This could be slightly bigger pipe or even square tube. The 1" pipe keeps the weight down and is pretty strong which is why I chose it. It is important that these two holes are drilled perpendicular to the pipe otherwise the holes won't line up on your claws. Use the center punch to prevent your drill bit from walking.

Step 4: Step 4: Final Assembly

Picture of Step 4: Final Assembly

Assemble everything using grade eight 5/16 x 3" bolts. There will be an extreme amount of shear force on these bolts and it is important we use hardware that can stand up to the challenge. In case you are curious a 5/16" grade 8 bolt has a shear strength of around 7,000 lbs and a tensile strength of around 5,000 lbs (these are rough numbers). Grade 8 bolts are indicated by 6 radial ticks on the head and are usually yellow zinc plated.

The pipe I used was a little over an inch in diameter, but I needed 2" in between my claws to make sure it goes over the stringers on the pallet. The 3/8" nuts slide right onto the 5/16" bolt and makes for a quick easy spacer. Make sure that your nuts are the same height otherwise you may run into some problems with things not lining up. I could have cut and drilled more plate to make a spacer, but I opted to use 3/8" nuts as spacers. Let's be honest, those pallets aren't going to break apart themselves while you are wasting time cutting and drilling spacers.

That's it! This isn't a glamorous tool, but it should be something that every maker using pallets can easily create. Happy building.

You may have mentioned it; and it usually goes without saying; however, using an angle grinder with cut off wheels is potentially very dangerous. I've had my cheek laid open when a wheel broke and the pieces flew by...face shield missing. The black snot is funny! A definite by-product. Good write up and good idea. Could we see a link to the pallet pry bar in action?

ThisIsMyNameOK (author)gmcpcs2015-09-28

The black snot is funny. But it's also not so funny, when you think about what you inhaled to turn it black. I think the mask is a wise idea, as is the face shield. Thank you for sharing your experience so that the rest of us can learn from it. (Not that I am going to be cutting anything with an angle grinder any time soon, but good to know regardless).

rybitski (author)gmcpcs2015-08-18

That is a very good point, cut off discs do break much easier than other accessories. Please make sure all shields are properly installed on any tools you are using. In addition to that always wear your safety gear. Bottom line tools are dangerous when not used in conjunction with safety devices and common sense.

Good idea. I work in a data center. We have a bunch of extra steel used to hang pipes and racks off the ceilings. Looks like 5/16", maybe 3/8" thick, 2" wide and about 10" long. I've found some good fastening hardware, too. I'm going to try to modify these instructions to use this so all I have to do is drill a couple of holes in some 1" steel pipe I have that used to be a handrail.

hantstwo (author)2016-08-29

how long is your handle? has this length worked out ok ?

rybitski (author)hantstwo2016-08-29

It was around 4ft long. Seemed to work well, but if you need more leverage a slightly longer handle would help with that.

pfred2 (author)2015-08-10

What do you have against welding?The pallet buster I made I welded up. It works good.

RobertG132 (author)pfred22016-02-09

congrats you own a welder, I don't can I come borrow yours? I'll bring it back in 6 months after I learn how to lay a 1/2 decent bead or stack of dimes.

pfred2 (author)RobertG1322016-02-10

You can't borrow one of my welders. But if you stop by with some beer I'll weld stuff up for you.

lime3D (author)pfred22015-08-22

Author's third sentence: "While I run a shop and have access to an array of welding and machining equipment I know a lot of people don't."

rybitski (author)pfred22015-08-11

I have nothing against welding, it would make a better tool. this was just a concept to help out those who don't have a welder. that's a nice looking tool!

mrclueless (author)rybitski2015-08-18

Thats what she said... Sorry it's was there and I lack impulse control.

RobertG132 (author)2016-02-09

why cut out flat stock? why not use hot rolled angle iron 2.5" x 2.5" bolted to a black pipe's end at 45 dgr flat side of it facing up, you can put splits in the ends for nail pulling. you're going to have to use case hardened steel bolts or harder. you could also let it pivot with stops and add a fulcrum point with extra angle iron or a short pipe.

There's always more then one way to skin a cat " No real cats were hurt saying this"

ThisIsMyNameOK (author)2015-09-28

Great job, nice clear instructions, and I like that it is an alternative for those who don't have a lot of fancy equipment. Since I only have a vague idea of what an angle grinder is, and no clue how to use one, I still won't be making one any time soon, but I will file it away for future reference.

(p.s. you should post an "I made it" comment on the original Instructable)

darren8306 (author)2015-09-21

This is AWSOME!

I didn't know you had done this, but I feel compelled to say that 'my' design was done with much help from pallet-loving friends, and is built on more knowledge than I have :)

This is a terrificimprovement! Thanks!

markman007 (author)2015-08-19

for the life of me i cant wrap my head around what this is or what it is for or how one would use it. Isn't that kind of sad? I mean I'm as sharp as they come and have a tool for everything. But this is the last thing i would grab for breaking up pallets so whats it really used for?

thansen871 (author)markman0072015-08-24

dismantling pallets so all boards can be reused. there are several variations out there.

Cheese Queen (author)markman0072015-08-20

Seriously? This kind of prybar gives you the appropriate angle and torque to get those twisted nails out of the stringers on pallets without breaking the wood to pieces.

Verga (author)2015-08-24

Excellent simplification for people with out a complete shop. well written clear directions and very good photos. A video of it in action would be a nice extra, but you still get my vote.

lmjservices (author)2015-08-24

A friend mine made 2 prybars like that they are a little wider between the forks and the forks are made out of heavy angle iron we use them to tear up the old tungue and groove flooring in a building he owns so we can get to the all joists and beams wich he sells to hi end builders they

Louise31 (author)2015-08-19

How come I can't print out instruction sheet for pallet pry bar - no welding.

damyar (author)2015-08-18

I dont understand , what useful this tools !?
fore carier some things or what or what !!?

rybitski (author)damyar2015-08-18

this tool is used to pry planks off of pallets.

wastubbs (author)rybitski2015-08-19

I'm still trying to envision how you use the thing to get the planks off. Is there a video of this thing in action?

rybitski (author)2015-08-18

you should post some pictures of you in action with this thing.

Old cooper (author)2015-08-18

Along comes the spoiler asking if we couldn't just buy some flat corner braces at a hardware store and bolt enough of them together, (two or three should do, shouldn't it?), to create the strength that you need? Saves finding that plate steel and those grinder blades.

rybitski (author)Old cooper2015-08-18

sure you could do that if you don't want to cut out any steel and it should like it would work. however, even stacked up the corner brackets wouldn't be as strong as a solid piece.
