Doing mitered half laps is HARD!
My new train table for my son has three new design features for me. Mitered
half laps, curved apron, and loose M&T's.
Finished it, now applying finish. Will post pics soon if your interested.
That's the one.
I needed to make a rabbet inside a frame that holds the train table top. I
thought miters would be the best way because you can do through rabbets
before assembly (regular miters are to weak for this project, end grain to
end grain). The other option was regular half laps than rabbet with a
router. This would of given me rounded corners that I would have to chisel
out, didn't want to do that. Im happy with the way 3 of the four mitered
half laps came out. 3 out of 4 isn't bad I guess...
I've never done one. I looked on the web to make sure I was thinking of
the same joint you are discussing. I guessed correctly. I'm now
wondering if they could be made with an accurate miter gauge setting
using a dado blade for the first piece. Then cut the miter on the
second piece and then run it on the TS with the miter gauge and dado
blade, making sure the height of the blade is dead on correct. Slide
work piece and repeat as necessary.
Did you use a router?
I did them on the router table using two different jigs and a pattern bit.
I tried them on the table saw with dado blade on scrap wood. My crappy dado
blade doesn't produce a clean cut so I went with the router.
Instead of doing it on the table, wouldn't it be easier to do this one
with the router in hand? I'd get a piece of sacrificial stock with a
45 degree angle cut into it that you can slide the piece to be routed
into (to support the router base as you work) and use a couple of
c-clamps to make a temporary fence for the router base to reference
itself against. The idea one of the others had about cutting the egde
of the joint to the correct depth on the TS before routing would work
as well as the temporary fence for this, if you prefer to free-hand
