bleedinblue Posted July 18, 2017 Report Share Posted July 18, 2017 I need to patch some errant dominos. I'm going to make my own so they dont have ridges. I know I can get it by trial and error, but in the interest of laziness, does anyone know the size of the round over for an 8mm mortise?

Tom Crawford Posted July 18, 2017 Report Share Posted July 18, 2017 Since the the dominos fit quite tightly in the mortice my assumption is it must be a 4mm radius since the domino bit has a 4mm radius. 2 Quote Link to comment Share on other sites More sharing options...
Brendon_t Posted July 18, 2017 Report Share Posted July 18, 2017 Not sure how crazy you're waiting to go but I have cut strips, drum sander to thickness and cut to length. Never worried a bit about the edges. I figure the strength is in the face to face grain contact. 2 Quote Link to comment Share on other sites More sharing options...
bleedinblue Posted July 18, 2017 Author Report Share Posted July 18, 2017 I'm not looking for strength, these will plug dominos on a show face. This is purely cosmetic, so I need to round over the plugs. Quote Link to comment Share on other sites More sharing options...
Brendon_t Posted July 18, 2017 Report Share Posted July 18, 2017 Then in that case, Tom above got it, although I doubt lazy will prevail. Gunna take some trial and error. Quote Link to comment Share on other sites More sharing options...
bleedinblue Posted July 18, 2017 Author Report Share Posted July 18, 2017 Trial and error indeed. I think it was 3/16th came the closest and got me passable results. Quote Link to comment Share on other sites More sharing options...
wdwerker Posted July 18, 2017 Report Share Posted July 18, 2017 Make them from crossgrain strips so you haven't got end grain showing on your patches . ( You aren't the only one to make that mistake !) 2 Quote Link to comment Share on other sites More sharing options...
Coop Posted July 19, 2017 Report Share Posted July 19, 2017 It sounds like you've already found a solution to your problem, but just thinking. Couldn't these be cut by gluing a domino to a piece of mdf and using the router with a template guide to make a template. Then using a larger guide to cut your piece, then slice it out on the bandsaw like you would when cutting plugs. Quote Link to comment Share on other sites More sharing options...
bleedinblue Posted July 19, 2017 Author Report Share Posted July 19, 2017 Way more work than this is worth Coop. I just planed some scrap to the right thickness, ripped to close width and used a block plane to finesse. Then some roundovers and I was able to bang em into place. They're not perfect but they're close enough for this project, and no one but me (and you guys, if I'm not careful with pictures) will notice. I didn't think to try to do face grain, but like with dowel plugs I'd probably just make it worse by trying (and failing) to hide them.

lewisc Posted July 19, 2017 Report Share Posted July 19, 2017 I remember seeing this a while back from @difalkner. Watch at about minute 3.55 for a very satisfying moment. Done with a CNC though. 2 Quote Link to comment Share on other sites More sharing options...
Tpt life Posted July 19, 2017 Report Share Posted July 19, 2017 No guide pin to start that routing? Like the music. 1 Quote Link to comment Share on other sites More sharing options...

I have to admit I dropped that piece in a dozen times before I glued it just so I could watch it again. I drilled a 1/16" hole through the bottom to allow air and glue to escape 'cause there was no way I was going to get the Maple piece in that hole with glue in it.
