A to B mandrel?

[aprayinbear]

Is it possible

I have an A mandrel and want to try some kits which require the B mandrel. Has anyone ever found a way to convert the A to B, perhaps with a brass or acrylic sleeve?

Trying to save a few pennies.

Thoughts?

I have both and I think the only way to convert from or the other is to use a collet chuck to use both size rods. I started TBC and love it. I still have a mandrel just because I have not made TBC bushings for all my kits yet....

Eliminate the mandrel and turn between centers.

There are risks with loss of precision with messing with thin sleeves, especially with the low cost of the 8 mm (B) mandrel.

The advantage of thicker mandrel is stiffness and resistance to flexing. You lose the advantage and gain hassle to save 10 bucks.

Thanks Everyone!

Monty I think you're right, TBC seems the best solution.... And while the cheaper kit bushings may not be perfect, they aren't perfect on a mandrel either. So that's probably the way I'll go for now.

Happy Turning! and Learning as I Go!:cowboy:

I use TBC except that I switch to the mandrel and the delrin finishing cones to sand and finish.

I've done that for awhile too.

Just tried finishing on the centers with no bushings and I think I'm gonna switch to that method.
