Similar but not quite. It's not easy to describe without a picture and I don't have the opportunity at the moment.
Imagine two wedges, one on each outside of the triangle, cut at 30 degrees, point towards the middle of the side, so the outer face of each wedge is parallel with the other. Then a clamp can be attached across the corner and because the wedge faces are parallel the clamp applies good pressure. It would probably need the internal wedges to set the joint up. But the external wedges need temporarily gluing so they dont slip.
How well it would work I don't know. I think I'd just put some screws in or pin it with a nail gun lol.

you have described my wedges exactly, they are fixed to the outside and they do present parallel faces so the cramps can be applied as you describe.
It's academic now because the cabinets are complete, but I'd love to see what you mean if you find the time for a drawing.

This might make a bit more sense? Not that different to what you did really ed, and TBH I'm not sure it would work.
Ant's suggestion of band clamps might be better. I still think I'd be nailing it to hold it whilst the glue goes off. Great challenge, kudos to you.
(Wow that was a faff, doing it on a phone)#19 Re: another cunning plan
Ah ha....
If you look again at my photo/drawing you will see that my wedges give the same pressure directions as shown in your drawing but have 1 more angled surface to attach the wedge itself to the side its on....so to speak...
you may have been misled because my drawing is at 90 degrees to yours......

more waily....
my normal M.O is to leave inlays slightly proud and then use the belt sander to make flush.
Not so this hardwood ply. The face ply is as thin as a fag paper. I learned the hard way.
The boards are also crap cosmetically, considering the price. So, out with the No1 plane and cabinet scraper.
I haven't used the cabinet scraper in many years, like meeting an old friend.
Also, getting used to the Draper router was a slow exercise. The depth guage rod is slightly bent internally so if you
wind the adjuster clockwise it gives a slightly different result to winding anticlockwise..mmmmmm....

#21 Re: another cunning plan
after Nick and Colin's thread I'm feeling distinctly less than worthy...but granny always said don't give up, so:
the drivers measured thus in the cabinet: and and so far I've got them to this in the cabinet:
that's with 2.47uf(8khz) on the fostex with no attenuation yet.
below 150hz I'm fairly certain is room modes, which I'm sneaking up on.

It's good that you had the violin just in shot to give scale reference, Ed.

Got them temporarily rigged for first impressions. I was tempted to up the hi pass to 3 uf but thought I’d leave it until things have bedded in. I’ve listened for 3 hours now with the filter at 2.47uf and no padding and…….
Considering that the seas are unused and the fostex have been wrapped up since Colin sent them…I’m gobsmacked. They are ever so slightly bright (as I suspected from the rising plot) but articulate in the extreme. I had to put astral weeks on first (it’s tradition) and there are what sound like accidental rim shots on young lovers that I’ve never heard before……It’s a very long time since I’ve tested a new bit of kit and heard stuff that I’ve never heard before…this bodes well…onward!
