So far I tried a bostitch titanium core bit in my drill press. After 15 minutes, all it got through was the paint. What do I need in order to turn a 20-hole hub into a 40-hole?
Ordering them might be the easy way. Be careful to only get US or western Euro made bits, makes a big difference.
40 hole hub? Good question, it just was not the question that was asked.
It is a hub from a green machine, direct drive w/freewheel. I want to build a mini highwheel for my girlfriend. I was actually unsure of how to lace it as well, since the 26" spokes would be the wrong length for this combo. So far I have straight-laced it using 20 spokes from a 24" wheel. Came out nice, but would look nicer with 40 spokes, and be stronger.
normal caliper brake on rear wheel. The sad thing is that I had a mini highwheel before with 27" front wheel, 12" rear. The front hub got trashed just by normal riding. I tried making it a fixed-hub, but no luck. So I eventually scrapped the frame/fork. Proving again why I should never throw anything out. So now using the bearing carriers from the green machine, I will have to build a new fork, and bend a frame myself. I have a tubing bender, but it was basically half of the kit ($10 at flea market). Has the main mech and dies, so I'm building a stand, adapting a solid shaft from an old furnace fan, and found a wheel at the salvage large enough to use to turn the center die. Having 20 spokes makes the wheel look more basic. Not sure about strength though, but it's a stout rim. Might try it as-is.
I do plan on going with an old wheel off the back of a tricycle, to increase the size difference between the front and rear and avoid any ride quality whatsoever. Probably going to try a narrower caliper off of a racer to stop the trike wheel. As long as the brake isn't in the front she should be able to stay in the seat.
Curious now...post pics. I have an old junior Wheelman frame that's missing the front wheel, pedals, and bearing holders. Slight bending in the fork blades, too. Figured I'd find a uni donor bike with lollipops someday and rebuild it, but I'd love to score a freewheel hub like yours.
Waiting on a camera I ordered. Mine fell off the table damaging the lense and A/V port. Green machines have been released with several different hubs. Some had 20 spokes, some 32, 36, and 52 I think. The mini hiwheel I had was a Columbia I think. It had the freewheel, and I was going to go with a uni hub as well, but this green machine fell in my lap at a great price.
Here's where I'm at so far. Couldn't get to fastenal though. Woke up to a friend barely limping his 93 BMW into my driveway, and had to get up and fix it for him.
Cutting oil helps keep the bits sharp and working when going thru the hard stuff. I use an old can of IBM heavy machine oil from the 50s that I picked up a few years back. Works great for drill and milling bits. Even motor oil can help, but burns off quickly.
