instead of making a clamp,measure top bike bar,cut same size opening in T fitting,then you can slip bike into the T-fitting.

I made this project, and ended up re-drilling and tapping because I didn't have the hole far enough out of the "clamp" area. I recommend placing your bike in the clamp to check the placement of the tap hole.

Awesome project, overall. My first unqualified success following an instructable.

[Waldie]

Neat idea. The only change I'd suggest would be to arrange the cut of the Tee so that the leg onto the stand-off was not cut - at least in the thread. Having a fairly heavy machine, I'd be a bit concerned about having the side mount spread, and drop pff the pipe. The use of a tapped hole to work the clamp, though, is most ingenious. I like it.

[headdead]

You are right. It would be stronger if you slice the tee without cutting off any threads. Speaking of cutting, a bandsaw with a metal cutting blade would be my preferred method.

what about angle geinder

[headdead]

All good points, Phil. With access to a welder (and welding skills) you could also avoid threading the pipe by welding a nut to the bottom.

[Phil B]

In my experience with welding nuts to things the threads in the nut somehow distort from the heat. I always have to chase the threads afterward. In Mobile, Alabama I toured a WW II battleship. All of the electrical boxes were bolted to nuts that had been welded to the steel plate walls. I have always wondered how they got bolts to thread into those nuts.

[kington99]

what welder are you using? electric causes far less localised heat distortion than oxy/acet

[Phil B]

I have a 220 volt Miller Thunderbolt stick welder.

[Esmagamus]

Then don't be surprised. Stick welding is the toughest welding process in common use, so it's natural to heat something too much, especially if you're afraid of making a pool of slag that looks like a weld but comes apart while cooling.

[Phil B]

I remember being surprised the first time I used a stick welder to attach a nut to something. The threads bound up pretty hard on the stud I tried to insert. What surprised me was that I had used an oxy/acetylene welder to weld nuts to things and the threads were fine afterward. I have just adapted and now chase the threads with a tap after welding.

[2 stroke]

why not put a bolt in the nut then weld it

[headdead]

I'm guessing, but would it work to weld the nut to the pipe while a bolt is threaded through the nut? Might the bolt keep the nut from distorting?

[Phil B]

My experience is that the threads in the nut still distort and removing the bolt causes a lot of wear and tear on those threads, too. Sometimes I just drill and tap the metal; but, if it is not thick enough, I weld an extra layer of metal over it, drill both, and tap them.

[Amir]

That's a good idea. I just discovered the nut distortion problem yesterday when I welded up an adjustable bike repair stand out of bed frames. I think your way would leave a much cleaner job. Thanks

[see spot run]

nice project. regarding the welding suggestion, there is plenty of debate about the potential health dangers of inhaling zinc fumes while welding galvanized pipes. In that case, it would be better to use black pipe instead of the galvanized.

[darnocpdx]

There is no debate (perhaps on these amateur sites but welders know). Burning Zinc is bad. galvie poisoning sucks real bad. I'm an iron worker/welder and have had galvie poisoning a few times. Each time it gets worse, and easier to get.

Cold sweats, uncontrollably shaking, fever last time I got it I soaked three sets of bed sheets in one night. And there is no cure or relief- you just gotta wait it out

Doing a little here and there wont hurt you much, but if you do it a lot or in an area without good ventilation wear a good respirator mask, not just one of those surgical masks, but a real one. You can taste it if you're in danger of getting it, but better safe than sorry.

[Esmagamus]

Not just galvanized pipes. I SMAW is used, the welder inhales poisonous fumes from the electrode.

is smaw stick welding thats the one i have but i have made a ghetto fume extraction system

[tructable]

 just a thought... it might be easier to drill and tap the tee before cutting. 

[nrathbone]

I found that I could get by with a 8" piece of threaded pipe, and still spin the pedals without touching the wall. This keeps the bike a little closer and hangs into the room less. Where I cut the "T" , 2 of our bikes fit in the "T" fine, but my mountain bike with big top tube hit the treads on the ends. As these threads aren't used for anything, I just knocked them off with a grinder, which smoothed the edges out nicely. Added about 3 minutes to the build time. Lowe's hit me up for $11 for the base flange (only had it in galavanized). Shop around. Remember to put through-bolt and tapped hole well BEHIND the part of the "T" the bike will lie in. My house is post and beam, so I just lagged the flange to a post in the basement. I can work 360 degrees around the bike. You could probably figure out how to hook to any basement column, post, something on your porch, etc.

[rtwitchy]

can you ad on to this and show what how you replaced the bolt with a knob?

[headdead]

My first attempt used schedule 40 PVC pipe. I was unhappy with the stiffness, so I went to steel. Schedule 40 could work, but you would probably need to add some kind of reinforcement to minimize deflection; also, I never figured out a good way to clamp the bike using PVC.

[m85476585]

It is good practice to always clamp a bike stand around the seatpost, not the frame, that way there is less risk of damaging the frame. This is especially important on expensive bikes since lighter frames can be weaker or easier to crush in the clamp (such as thin-wall steel frames), and because (obviously) the frame will be more expensive.

[Esmagamus]

How right you are.

[ChrisCanMake]

pretty sweet and simple build - thanks!

[ebergh]

Very nice! Different diameter shims will make it useful for a variety of bikes around the house. How about using a 3/8" eye bolt w/ a large eye to close the clamp? It will give you a good gripping surface and adequate leverage, plus it may be less expensive than Rocklers plastic knob.

[dchall8]

I like this idea. At first I was worried about the little screws holding the flange to the wall but now I see you used 2-inch lag bolts. This should be fine if the weight is only bike weight. I don't trust myself not to lean on the bike so I would go with 3-inch lag or even a 5-inch through bolt.

[Phil B]

This is clever. I would not have thought of slicing the Tee so one side has enough threads to hold on the long nipple. Were I to do this project, I would probably use black pipe and weld the larger piece of Tee to the nipple, but not everyone has access to a welder. The basic idea you used could also be adapted for a free-standing floor work stand. The cost of the project would be more advantageous if a person could find some scrap pipe parts in a junk box.
