This is the replacement for the dovetail guide that comes with the dovetail jig. As it took me awhile to learn how to set the router into the jig without gouging it with the router running I recommend you buy replacement jigs with the machine so that once you've learned how not to jack it up you'll have the replacement on-hand
Still trying to master it. The directions are complex and you absolutely have to read them multiple times before you get started. Some of the things that are just mentioned in passing turn out to be critical. Whatever you do, don't practice on plywood and especially don't practice on the plywood that comes from big box retailers. The laminations come apart and throw the bit into the guide. I'm down two guides to this. Following the directions gets you in the ballpark. The bit height is fairly straightforward but you absolutely need to fine tune the guide positions. Getting it set up to do an accurate job definitely needs several rounds of trial and error on scrap and the scrap needs to be identical in type and size to the final work. I can believe this thing is going to work but I am only halfway through the training course required to make that happen.
I ordered this template because mine broke. I did not realize there is two different Rockler jigs. One has been discontinued and its the one I have. I went to return the template but the shipping was almost as much as I paid for the template. So now I am stuck with a useless jig and a useless template. So make sure which one you have before you order.
I have a 12” half blind dovetail jig #311373. My 1/2” template has 4 screw holes for attaching to jig. It is 20” x 2 5/8” . This item #27386 only has two screw holes for attaching. Can it be modified or used on my older jig? What other options do I have to replaced the damaged template?
