Made this jig back in 2008 out of KD hardwood using Kreg t-tracks. It wasn’t till mel52’s latest project that mentioned his Juice Groove Jig.
that made me realise I still needed to fine tune my attempt at this “version” of the Festool MFS 700 Routing Template.

The design was limited by the length of t-tracks I had available at the time and I haven’t had the need to make a bigger one.

Sometime between initial build and last use,

it was shortened to just the track lengths as I couldn’t reduce it enough for small jobs.

This latest modification

flattened the knurled knob access circle so that greater pressure could be applied to ensure that 90° could be achieved between the adjacent sides.

Unlike mel’s jig, this one sits on top of the job so there is an option to mount some Festool non-slip rubber strips if needed,

Thanks for looking.

I have made a video that hopefully will show a bit more about the jig (though not the use) and also a Sketchup animation of the jig and the box I have designed.

Yep I actually have one of those . ....not quite as fancy as yours I might add
Its a frame and sections which fit inside to make it smaller .

Something if I remember I will pull out for Sunday best.

Very interesting LBD. Looks versatile enough for most projects. You’re giving me ideas.

This is a nice one Alex. I made mine out of 20×40mm ALU. And a smaller one out of 20×20. The 20×20 is for sure to smal. I like your version above my own.

Great design LBD. Now this is much better than when your burning cardboard.

Wish I could count how many times I made that style of frame/jig to hold stuff square, only to toss it back into the scraps pile when done.
Something more permanent like that would be bonus, I like your details Duck!

(have fun making a box for that 8^)

I have yet to need a similar jig but I certainly do appreciate the ingenuity involved. Nothing compare’s to having the right tool at the right time

Dang, that looks like another jig to go on the to build list:) LOL! I have that same little router but in the 18V version.
Think I paid $30.00 for it and just can not kill it!

Nice jig Duck. Anything that can change proportions smoothly is a good thing. Life is not one size only.
