How to change a bolt pattern on an axle shaft using a DRO

[@malibye]

As a journeyman machinist I think you did a great job with this video. To me the hardest part is usually how the work will be held down or fixtured for machining! Much better and more accurate than leaving the axle on and using a cheap plastic pattern with a hand drill.

Usually you see this kind of work liquid cooled - as the heat from the drill can warp the disc

It didn’t seam to heat up to much but i do run a noga mini cool mist sprayer now.

You could also center drill all the holes then just drill with drill bits as needed!

Im sure there is several different methods whatever works right?

Nice work. I’ve been considering doing this for the local race guys. Your setup looks nice and rigid. This video gives me the confidence to do it. BTW, have you considered verifying hole diameters with gauge pins?

[@ht_fab3525]

I did not gauge pin them i just kinda went with the average press fit tolerance and measured with small hole gauges seemed to be a good fit when pressed in! Thanks for watching

Very cool man awesome work!
I know this is an older video but I have a couple questions. Where are you located and how much would you charge to do a job like this for a customer?
Thanks

Thanks for watching. Cant see it costing much but i just machine as a hobby right now. In ct
