And did not fell that he had the hand strength to true his 1996 wheels up on the Derbyworx wheel shaver and do his axles.. plus he felt like he would miss them up!
I told him the same holds true as for me doing them as well.
However I did have him check his wheels on the run out gauge all were 4 to 5 thousands out of round.. so he asked if would take over to true up his wheels and work on his axles
and that he would do the polishing prep on his wheels and axles when he was feeling better.
I told him I would help with these stages.. but he has to keep working on it to get it done intime for his race.
He was right about hand strength alright.. these older wheels where a pain to shave and true up
It's been awhile since I've used the Derbyworx tools and shaver to true up wheels with..
I had some grooves and scratches in the tread that I need to fix. (so ill need to work on sharpening the blade back up!)
I'm going to try some Triple Ott (0000) Steel Wool on the treads to see If I'm able to work down the scratches some what.
Scratches:
Removed some what:
Wheel run out:
Best I could get them to was 3 thousands out of round.
Charlie also seen in David Meade's speed secrets book the grooved axles he wanted to do for his axles this year.
EDIT: Forgot these images of axle prep and putting the grove in the axles..
After all the burrs and bumps on the axles were removed with out spinning the axle in a drill..
I moved on to marking out where to cut the grooves in at.. to be cut in 1/16'' from the axle head.
The lowest rpm range is 620 the highest rpm range 3100 on my drill press.. for sanding axles I keep it at the 620 rpm range..
( For cutting groves I find it easier to do in a higher rpm range.)
With the drill press set to 3100 rpm and the axle chucked in.. I set the drill press table to the mark on the axle using the file.
With the axle spinning at 3100 rpm I keep the file flat on the drill press table and move the file back- and- forth while it cuts in a grove..
I like stopping the cut as seen in the image at about 1/16" as well.
For tapering the axle head I'll drop the table down and use a small triangle file.. while holding the file at an angle seen in the image.
(However I holed the file with both hands to tapper the head back.
Some times I'll even use a Dremel cutting disk to cut a small grove in where the shaft meets at the axle head ..
plus it help's to get at the hard to get to.. 2 burs that are up really close to the axle shaft and axle head.
Axle after the file work was done for the shaft groove and tapered axle head:
For cleaning up the burrs from cutting and shaping with the file.. I'll use a popsicle stick and 600 grit wet dry sand paper to start the axle sanding prosses.
What the axle looks like in the first stages of sanding.
Here's the work Iv helped him out with to keep his build moving forward and so he can finish the polishing of wheels and axles that he likes doing best.
.Well when he is feeling better he will be back at it.
