Just got my first 12th scale car and I'm hooked. Also my wallet is a lot lighter, so I'm thinking of using a old Sherline lathe to true the tires. I intend to mount a SaburrTooth burr in the tool post at a similar angle as the Hudy burr. I haven't made the arbor or the burr mount yet. Before I spend time on this, I have a few questions.

I has anyone measured the run out at the arbor on a quality tire truer? Depending on how my 3 jaw chuck closes I could have as much as 5 thous. run out.

Is the foam dust corrosive or likely to melt when sticking to oil and grease on the lathe?

What rpm do tire truers run?

Thanks
