There have been a couple new members looking for a good way to profile sand rims to match top and back domes without buying or making sanding bowls. This is the method I use in the beginning. It is a sanding bar made of 1 x material with wedged ends to replicate the bevel. It is simple and cheap. You must move you pivot point in the oposite ditection you progress your sanding. This will match very close to a 15' back dome and a 25' top dome. You will want to adjust the bevels to the slope of the domes you use.

Cool, are you happy with the results Michael? That reminds me of my first sanding board.

Flat for tops, before the dome of course.

The other side of the two by four with glued on 80 grit was 15 foot radius.

What a workout getting one ready but by golly they fit together and I was happy. Thanks for sharing that. Someone will have it built before nightfall Michael..... Dickey38744.6111689815

I don't use it any more as I have sanding bowls now. But it worked well back before I had sanding bowls. I posted this for the newbies that did not want to spend the money for sanding bowls on ther fist few projects.

They need to know that to make this work requires working their way around the assembly, all ways moving the pivot point perpendiculat to the sanding point and in the oppsite direction that they advance their sanding. This renders the near dome profile to the end blocks and linings. This is a take off of the process described in the StewMac assembly instructions

Yes Bruce, this is a work out, but gets the job done. MichaelP38744.6368981482
