I recently purchased a Leigh D4R Pro jig. Have been trying to get it calibrated to run variably spaced half blind dovetails in 3/4" soft maple stock. I first ran the tail board as instructed in the manual and all went well. Then moved on to the pin board on the jig top and that went well too, except that they needed to be a little deeper. So, I adjusted the depth and rerouted the same pin board. That produced a nice fit though a little loose from rerunning the same board.
I decided to practice one more time to make sure it wasn't an anomoly. Again I ran a new tail board and moved on to a new pin board. Since that time, I have not been able to rout the pin board without the front edge moving right, away from the front left stop. The rear stop stays in place mostly but the front moves as I rout left to right. I've done the following to try to deal with this:
1. tighten the pin board side clamp. At this point, it is beyond a simple thumb pressure as stated in the manual
2. add and also remove a 3/4" support out on the right edge of the fingers.
3. tighten the finger assembly tighter against the pin board.
4. tighten and loosen the right edge of the pin board clamp.
5. the manual says take 4-5 light passes and i've certainly done that. I'm also trying to just let the router do its thing rather than push it into the wood.
Nothing has worked. I'm sure I'm doing something wrong but have no idea what it is...
I appreciate any help.
