you have to keep them slightly underinflated in order to fit the mini-bike frame?



No, thats 1/8 at full scale. At one third they are about .045 too big so it wont be noticeable.

Well I finished half of one wheel before snapping a very expensive and fragile cutter. I am trying to locate another one right now. As soon as I get my paws on one i'll get going on the other half.


I was going to make 2 wheels (4 Halfs) so i made a fixture from a small piece of Corian.




The blank is loaded and because I just made the fixture, all I need to do is set my Z height.




All the cutting is done first.




Then the holes are drilled.




Then i lightly dusted the wheel with the sand blaster to remove the machine marks and get ready
for some white paint.

It was a 1/16 inch ball nose cutter with a 1 inch reach before the shank goes to 1/8. I think I paid close to 40 bucks for it. That doesn't sound expensive but most of my cutters are under 5 bucks each.



EDIT:  Just scored a cutter with a .750 reach and 1/8 depth of cut for 25 bucks

ever use a roughing cutter to hog out the bulk of the cut?

I try to minimize the tool changes. Things just come out nicer that way. I try to combine tools also like for instance, The radii in all of the corners are a .032 radius so I bought a 1/8 inch cutter with a .032 radius so I don't have to go back and clean out all the inside radii after cutting with the 1/8. Works out good because the home built mill doesn't like cutters much bigger than that anyway.

Nice job again.  I like the sandblasted finish, I need to check into that.  Do you have a cabinet type, or what?

Mmmmm.... Shiny!

It's a small cabinet about 30 inches wide. It has the vacuum unit with it. It's the second one down the page for $875. I got it used with a spare bag and 2 types of media for $250

Awesome Steve, I just love the wheel. Can you place a penny next to it just for size comparison? Have you found anything to make the handle bar grips yet?

I'm not real happy with the wheel. I have a new plan and some new Gcode for the next try. I'll try to remember to spot something next to the wheels in the next shot. If it helps it was 1.625 inch barstock.

Haven't even thought about the grips yet. I'll figure something out.

Somehow i missed this last update Steve. The wheel looks great to me and I whole heartedly agree that bead blasting gives a very nice finish in lots of cases. Though I haven't used it with painted parts like the wheel, I suspect is will help paint adhesion too.  Looking forward to the next update now!!

I finally have a frame in rolling form. I made the rims and other axle parts today. I had to make the axle bolts and bolts to hold on the forks. #12 bolts are not easy to find.

I doubt it. It needs to be the original color, or one of them. They came with the Chrysler "HIP" colors on them. Plum Crazy, Sublime, Lemon Twist, you remember. I think I can get most of the colors in Testors model paint and air brush it on there.
