Another Domino question...

[Lou Miller]

I'm ordering my Domino this week. I'll primarily use it for cabinet carcasses and stuff. However, since I still do my fair share of trim carpentry, I'm wondering how well this thing will work for casing miters.

Right now I reinforce most of my miters with biscuits. I'm just wondering if the smallest dominos can replace the biscuits? I've never had a domino in my hand, so I'm not sure. Does anyone that currently have one think the 5mm dominos will fit into a 2-1/4" casing that is 5/8" thick? I ask about that size because its the smallest I ever use. Often times, biscuits don't even work with that small of a casing.

Its probably overkill, but if its fast and easy enough, I'll use it for that.

The first job I'm going to use it for is making some (40 or so) very large window sills. About 20" deep. I have to do them all on site, and want to get very good to perfect alignment with my glue-ups so clean up time is limited.

I think you can put domino's of 5 mm in a mitered joint of 5/8" (or 16 mm in newspeak), but it will be a close shave. If you set the depth to 12 mm for both parts of the joint and cut the tenon to 22-24 mm in length and drill at a distance of about 5 mm from the innercorner, you just stay inside the boundaries of the exterior surface.
With the trick with the sleeve on the guiderod, you can reduce the depth even more.
For some drawers with butt-joints I made 6 mm deep mortises in 9 mm plywood. No sweat, just a calculation for the sleeve-length.

Hi Lou,

5/8 is around 14mm which will easily hold a 5mm Domino tenon.  I use them to glue up book matched panels in 10mm thick material all the time.  One thing to keep in mind is the minimum setting on the Domino fence is 7mm from the bit center line.  That way a 10mm cutter will still pass 2mm below the bottom of the fence set a min height.  7mm would be near the center line on 5/8" thick material.

Hi Lou,

Jerry,

While I think I understand most of your response 5/8 is much closer to 16mm. 14mm is .5512 inch or just shy of 9/16 inch. When you are using the Domino with 10mm panels do you use a spacer between the panel and the fence?
