Yes, Darin, you DO understand the nature of my question about what width
boards it will work on. The two detailed descriptions of it's operation
on the 'net were provided for me, which I read in total. The
explanations tend to focus on a 3/8 and 1/2 bead for 1/2 and 3/4
material, so naturally I had wondered if it would work like with a
biscuit cutter whereby you could insert a slot into the face of an
infinitely wide board, if desired. I now understand that with longer
bolts, that's doable. At least two users report slippage during
drilling. Must the fixture be tightened unduly tight to prevent movement?

It must be well clamped. Stuffing it in a vice would do. I wouldn't call the
clamping pressure 'undue', simply adequate to stop the jig moving when the drill
bit tries to wander off down one of the already drilled holes.
I bought a smallish ratchet clamp last night that should work fine. I'll try it
out when my new tenons arrive.
Even if the new tenons are still a tight fit I do not intend to give up on this
contraption. If I have to I will have the thing drilled out to 10mm for the 3/8"
block and 13mm for the 1/2" block, but first I will give the supplier the
opportunity to fix it by making the tenons a smidgen smaller.
I found a couple of things make the beadlock work better. I added lock
washers to the tighening bolts. Held the jig tight and kept the
drilling block from moving. I also run the drill in and out a few
times. which helps keep the tenon material from getting too tight. I
used mine to put together a porch full of screens for a friend. Also,
if you have a router table, buy the cutter to make your own tenon
You've gotten a ton of responses so far. I bought it early on to avoid
learning to make "real" M&T joints. My experiences have been more aligned w/
Gandalf: easy to bugger up the mortise, since the jig often slipped drilling
the "B" holes. [ Switching to Bessey's and cranking them down has helped. ]
And, the last few dry fits were way too tight. (Don't recall that being the
case when I first used the jig.) I ended up shaving some edges on the
bandsaw to ease the fit.
Would I buy it again? Nope.
Will I continue to use the one I have? Maybe. Rarely. Time to master (a)
M&T's and (b) making my own loose tenon stock.
