TRNW-2: 10R80 Solid Ring Sizer

[Dan Hogan]

If you have access to a 3d printer or buddy with one, there are good sizers available online. I printed a set for myself and a few nearby shops.

Pretty good design. 3d printer is a good asset in an auto shop now. Just buy a decent one you can use out of the box.

Hey Group

What do y'all use for Re-sizing the Solid rings? Im using the actual parts they seal on for re-sizing, but it takes too much time. I would love to speed up this process.
Ive seen some aftermarket tools on Ebay etc, but would like to find out what the best tool and/or kit is
for this job, Aftermarket or OEM.
Thanks!
