I recognize the seat in the photo above. Standard Virco stacking school chair seat.

A few comments on your axle. May not make much difference for what you are doing, but you should have used fine thread. That gives you the ability to us a cotter pin and get a little more adjustment out of the castle nut.

Also, you are going to want to make a small spacer to go over the axle first so it goes up against the welded area. If you have a 5/8 drill bit, you can use a piece of EMT for that spacer. The 5/8 drill simply takes out the boogers and really doesn't remove much material. You only need a spacer about 1/4 to 3/8 inch. It will help keep your bearing from getting stuck on there.

It also may have been better to use a solid rod for the axle. That way you know the axle is straight. Welding bolts on is really difficult to get them both square.

But again for this application it is probably fine. For our 4 wheel stuff, I prefer a straight axle because wheel alignment is critical to us. We also mount the axle in bearings so it can spin in the chassis and the wheels can then spin on the axle. You may want a little more rolling resistance then that!

Shouldnt the 'V' cut for the headtube be in the other direction?


Yes sir, good eye. I got a bit excited and started notching the wrong side for the axle. I'll be chopping that off and notching it the correct way. Luckily I measured out a bit extra for mistakes like that.

I understand the need for a spacer, but I can't picture what your suggestion is, or how the 5/8 drill bit and EMT is involved...help?

Lots of good points in there though. I spent awhile trying to get those axles square, and I got almost perfect, but they'll never be perfectly straight. That solid axle idea is a good proposition, may use that if I end up building more. The only solid axles I had seen used were live axles which I didn't want, but I never really thought of just welding them on and using bearings.

Aha, i thought so. Its looking good so far! Are you cutting the headtube from a existing frame?

Im not sure if to use a cut down frame for the main part and stick the axle on the back. Or do what your doing and just stick the headtube on a custome frame.

I don't know about the drill bit, but the EMT will be there to scrape you off the front bumper of the car that you run into.

EMT electrical tubing is almost the perfect size to slide right over a 5/8 axle. But it needs to have a 5/8 drill bit run through the inside for a clean up cut before it will fit.

The nice thing about using that as a spacer is the thin wall. When it is installed it will sit only against the inner race of the bearing. So the rest of the bearing is able to spin free.

We use these a lot on our down hill cars running a 5/8 axle. usually they are only about 1/4 to 3/8 inch long.

Also for an axle, you can just use a piece of 5/8 rod. BUT you need to take your bearing with you sometimes. Depending on where you go, some 5/8 rod is exactly 5/8 OD which creates a problem when you try to put an exact ID 5/8 bearing on it. It's too tight. But most 5/8 rod is just under 5/8 so the bearing slips on nice and snug but isn't stuck.

If you have a threading die you can thread the ends and use a nylock nut or a castle nut and cotter pin.

If you don't have a die, just drill the ends for cotter pins and washers or spacers until you get the slack out.

Ahh! Makes sense now. I don't have any tubing that size, but i'm hoping I can find some thin wall bushings in the bucket of hardware in the garage.

Yup, I just hacked the front forks, bars, and headtube off an old bike. Disassembled everything, welded headtube on at 28ish* angle, put everything back together.

It's starting to look official...

I kept the original seat frame and I'll be welding supports to the trike frame and axle

It just seems like you need someplace for your feet. Maybe BMX pegs on the front axle.

That's what I'm doing Smile I was going to use a trike front wheel but the pedals will get in the way at that speed

You have plenty of hills big enough to play with that thing! After all, how fast do you really want to get it going?

Sudden stops hurt!
