I may be impatient but don't have a Hudy but an old school truer so I'd like to know how you guys make a deep first cut to a fresh donut to cut back the time it would take for final truing. Also how you'd keep the first cut flattish?

Joe,

I've done it with a #11 X-Acto blade coming in the side of the tire in the past, but not in a long time.

Can you post a pic of your tire truer? "Old school" doesn't say much, as an old school tire truer to me is a wide emery board!

This is the deal.

I can do side cuts for width but I'd like a quick meaty flat cut and not leave the thing on to cook the donut.

If you can change the cutting disk, try using a coarser sandpaper.
 
Otherwise, a hand drill can be used to cut the worse of the rubber away

R-Geo makes a tool that can reduce the diameter quickly. A pointy rod on a guide.

I've found that cutting "Wonder" rubber just takes a lot of time and patience. Go too fast, you overheat them and they start to smoke. Go too slow... well... it just takes a long time.

I made a tool post for my Dremel on my Sherline 3" lathe. Cut-off wheel does just fine for rough cut.

[Joe Rose IV]

You still use that set-up?

Easy



Get a FITT tyre truer and cut all the cores and sides off you want quickly

I did all these in 30min while talking on the phone, on my kitchen bench...

I have a tire truer similar to yours and the one thing that helped immensely was the sandpaper. I went through 3-4 different types before finding the best cut and it turned out the type of texture you get on sanding belts - the red ones - work best. I also took a piece of piano wire and ground a flat with my Dremel at a sharp angle, which I use to cut the width and do the first deep cut. Not as good as some of the tools I've seen but it works

I made a stepped slug in my lathe......One end fits inside the rim,the other is the diameter I want the first cut.....Push inside rim,use exacto to rough out tire....Quick and painless.

What does a FITT tyre truer (did you mean "tire" ? Just kidding!) look like?

This is it with the drum off, and coring needle fitted
