You can't exactly, Grizzly do not have a retail presence in the UK, however you will probably find that their jig is a generic version of the one that I believe is available from Rutlands. Similar types come up from time to time on EBay and I recall one being offered on the For Sale board her fairly recently. Just check your mitre slot sizes are compatable.
If you get one with the wrong size guide bar, it is trivial to make and fit a different size one.
Standard ones seem to be 3/4" x 3/8"
Powermatic have a very nicely designed one http://www.thewoodwhisperer.com/videos/ ... oning-jig/
and Axminster are starting to carry some of their products so maybe one day?............
thanks for your replys, not sure which way to go ,came across the powewrmatic jig and it looked so good ,only but is its not available in the uk , proberly buy one from rutlands i guess, not as expensive as well
I don't understand why you would want to buy such a thing. I really don't.
They are slow to set up, slow to move from one cheek to the next and difficult to reset if you need to make a remedial part. Plus you have to remove the saw guard to use it.
Why would anyone in their right mind want to cut tenons in that way?
I really don't get it.
