Topic tags/keywords: router dovetail jig

I am a woodworker reclaiming Old Growth Timbers from area barns, structures etc. and making furniture. I am looking for a used Porter Cable 24” Omnijig Model 77240 to incorporate some variable spaced dovetails on some chests I am working on. Please advise if anyone knows of a reasonably priced used unit in good shape as I am stretched having recently begun this endeavor and purchasing other tools & machinery.

Regards,

I’ve got the PC 24” Omnijig and have not been pleased with the results. Whenever I do one-pass dovetails for drawer boxes, they never fit right. I can go through dozens of tests fits and it just won’t zero in to produce a good quality joint. I also noticed the template used for one-pass dovetails flexes a lot when I tighten the knobs to hold it in place thus throwing off the joinery even more. I’ve tried the standard template that comes with the jib in the box with a little bit of success but not much. Might want to look at the Leigh dovetail jig instead. I have more luck with that one then the PC.

Overall if I had it to do again, I wouldn’t have purchased this jig for making drawer boxes, that’s for sure.

Is yours the model 77240 with the adjustable finger template which enables variable spaced half blind and through dovetails? I have a cabinetmaker friend who raves about this model. In any event I have seen an abundance of Leigh DR4 24” models for resale.

Please advise further as I should perhaps reconsider.

Yes – mine is the 77240. It has not impressed me at all. Sloppy adjustments, flexing of templates, inaccurate cutting.

It has the adjustable finger template as well as the one-pass dovetail template. I’ve not had good results with either template. I even used the specified bits (Freud) and the Porter Cable accessories. I even use the PC 690 router. Tried several of my other routers with similar results as the PC router.

Went to the Woodcraft store where I bought it to see if I could get some help with it and they were clueless as to why it produced such bad results. They then showed me another jig and tried to get me to shell out even more money (NO WAY!).

I wish there had been some good reviews of it before I shelled out the large amount of money to buy it. I wouldn’t even feel comfortable selling it to someone now because I know they would not be happy with it. So I’m stuck with it. :-(

I would not recommend this jig based on 2 years of trying to get it to produce even half-way decent results.

Wow, I’m sorry you had bad luck with it. I have had mine for two years now and love it. It did take me a couple of cuts to fine tune the adjustments but after that. I get perfect cuts each time. I also make sure that I always put in a board in the unused part of the template with the same thickness of what I am working on, and I never have any flexing.

One thing I wished I would have checked into a bit more was the price of the accessories. Damn they are expensive. I am over all happy with mine. Note: I had to watch the video a couple of times. I had a tv in workshop. I would watch a step, Pause it. Do the step, then unpaused.

Take care,

Have your say...
