question about Leigh D4 jig fingers

[Vern]

I'm trying to get set up to cut end on end dovetails with my Leigh D4 dovetail jig. I read the book on setup, then I re-read the book on setup. Thought about it for a couple of hours, then re-re-read the book on setup. I got the test stock prepared and set up the jig to cut the tails as it says to do. I tightened the fingers pretty snug, but didn't want to overdo the tightening. Ok, so I cut each end of the tail board. No problem. I flip the jig over and line it up to cut the pin board. I cut one end of the pins and take it over to see how the fit is with the tails. Not good. Irregular spacing and sloppy. I go look at the jig, and a couple of the fingers had vibrated slightly apart from one another. I checked the tightness of the screws on the fingers and they seemed to still be tight. I can't feel any slop in the fingers, they don't move or wobble. I'm worried about really crankin down on the finger screws. Has anyone else had this problem? Any suggestions?

The BEST advice I can offer (D4R owner) is to call them or send them an e-mail. They have VERY good tech support (I know first hand).

Only time I've had one move was when it was slammed because of a climb cut and the router kicked back.

Re-read the sections on direction of cut and retry a test cut. Since that happened I've been very carefull not to exert any more force than necessary when routing/following the fingers ... easy does it.

Are the fingers set down firmly on the spacer block underneath? If they are not sitting flush on the block on both ends, this might be the problem? I havent had any problems with the fingers vibrating when they are set tight on the horizontal spacer piece.

Yes the fingers are flush. I think that the response from swingman may offer the most input. I'm thinking about my technique, I may have been pushing on the fingers too much. It's a little intimidating when you're trying this for the first time with the honkin router screaming, trying to keep it flat on the fingers and "gently" moving it between the fingers. I may have been applying too much pressure on the fingers moving between them. I think I need to go slower. MUCH slower, and try it again. I very much appreciate the responses. Vern

No.

Call Leigh.
