Sorta been awhile since my last update, but I didn't really have that much to show for. I had started on the wheels almost a month ago, with this plan to make the tires out of rubber washers. This entitled cutting them to size, trimming the width, and inverting them......long story short this never really panned out. So only today, did I scrap that plan and moved on to a new one.
I finally went to the basement and got the o-rings out and to my amazement their was a size that was pretty much perfect for the gears. I had thought about using o-rings orginally, but I didn't think I had any the right size....d'oh. So a month later of useless work, I finally got the wheels near completion.
O-rings come in many different sizes, and the set I have has about 225 pieces, with sizes all under an inch. So if you're looking for a specific size, you'll more then likely find it.
After finding the closest size to fitting my gears, I did some test fitting. This helped me figure out that the gears would have to be slighty smaller to fit inside the o-ring. Thus I got out the industrial files and started shaving down the brass teeth of the gear. I didn't shave the teeth flush off, since the o-ring wouldn't have a nice tight fit.
As for the files, any grit/groove is fine. However you'll want to use the ones with much bigger grits/grooves, that way it doesn't take you forever to shave down the teeth.
Then after the shaving down of the gear teeth, I slipped the o-rings around the gear. Thus making a wheel(even if it is a bit crude.) Now I have to actually glue the o-rings to the gear, which I have to do later today.
As for the axle supports, I've finished drilling out all the styrene and collecting all the pieces I need. Thus I can soon get to putting together the front axle, and putting on all three wheels.
Thanks for looking!
