Actually, just for the sake of reference to the OP of that pic. That wasn't a picture of the jig I built. Just one I found on the web that looked similar.

I went a bit nuts and had the bottom brace adjustable via two bolts through slots in a bottom piece of MDF. Just in case I ever wanted to use different sized crown modling with it.

Of course I never did so I just wasted time unless another project comes up.

"Useless Project" or "One-Time Jig" would both be good names for a band.

Sadly, I guess I just need to watch some videos. I can't get it in my head. Is this just for the corners?

Yup.

Jeez, Mark you're slipping.

Don't you mean...

Wasn't "One-Time Jig" the title of the Negative Orange Emo/Irish album?

I don't know, but I'll bet CV has the liner photos of leprechauns in black eye liner to prove it.

Money.

I thought the US flag on the door in the back was a giveaway.

So, did you or did you not spell "ceiling" correctly on your jig?

Almost 50% of the posts in this thread happened today and had nothing to do with a subwoofer...

Just a normal day at on the Axiom forums.

Neither Chess. I used arrows.
