Thanks to ratchet for his jig he posted. I copied his expertise and will now pass them off as my own. I’m extremely excited about finally having this jig completed. This was my first time using T-track and toggle clamps. Bought the clamps and track (and an unseen incra miter jig) from woodpeck. And got the 129 piece jig set from Rockler while it was on sale for $50. It’s fun to think about the jig possibilities now that I have those items. I love everything about this jig EXCEPT that the toggle clamp arm does not reach the piece, so I keep some scrap blocks inside the carcase to use as clamping blocks. I don’t know any other way to keep the clamp moveable on the 3/4 ply AND reach the workpiece. Not really a big deal. I made the stops and edge guide out of 3/8 acrylic that I bought from ebay a year ago. I just like the look and feel of acrylic. It’s smooth, transparent to see the work better, and strong. And the last pic is my very first mortise (hopefully of many). I’m keeping it hung on my wall as a milestone, at least for another week anyway. Thanks again to ratchet for posting his jig.

So exactly what kind of mortises can you cut with this thing?

What’s the advantage of the front piece being able to slide up and down? I take it the router can slide from right to left to cut the length of the mortise?

I do not consider your jig to be a rip-off at all, but rather the next step in its evolution. Well done I say!
It looks like it makes really nice mortises.
Thanks for posting.

nice jig. making a loose tenon/mortise jig like this (but a LOT more basic!) definitely was an enormous boost to my productive abilities, as i’m sure it will be for you. pretty much the only thing that needs to be dead on is maintaining the right reference face. If on mortise is a little too long, the strength of the joint is still mostly intact and will be aesthetically perfect.

Bob Areddy, the front plate slides up and down to make sure that whatever width stock that I’m mortising will be flush with the top plate. The stock sits on the front sliding plate and I’ll raise/lower it to flush it with the top plate/ bottom of the edge guide. I set the stops before cutting anything, making adjustments as needed for that first mortise. Then they stay in the same position for repeat cuts. I’ll also clamp a stop block to the front for the wood stock. Thanks for looking.

Is it a matter of using a longer bolt like this one to reach your stock ?
http://www.rockler.com/product.cfm?page=18086 they come in 2” and 6” lengths from Rockler .I’ve seen them elsewhere as well.

-- I'm absolutely positive that I couldn't be more uncertain!

Dusty, that’s exactly what I need. Guess I have to wait for another free shipping deal.

Jon,

As I plan to copy your jig in the future, do you think that having a stop for the piece being cut would be useful for when you have to cut several or many identical pieces?

Fireguy, a stop for the workpiece is definitely essential to this jig. You can build it into the jig itself. However, I simply plan on clamping on a block whenever I need identical pieces. Good luck.
