Topic tags/keywords: jig question

Hey gang,

Long time no chat… ;)

Trying to get myself back into woodworking after a long absence. Thought I’d jump in with both feet and finally try using my Porter Cable dovetail jig to make some 15” x 15” x 15” boxes for my wife to replace some ratty cane covered ones we’ve had for years.

Can anyone point me at a decent tutorial on using a P.C. dovetail jig? What would be the best dovetail cut to use the first time I try this? I’d love to do a through cut so you can see the dovetail.

I don’t have a jig wide enough to do a 15” glued up board. How do you properly cut two board so the dovetail properly fit together after everything is glued up?

What would be the best thickness to use for floor boxes. 1/2 inch? I’ll be planing down some antique pine board for the boxes.

Thank a lot for the advice.

Milo

I’ve had mine for 2.5 years now and have never been able to get it to work right. Took it back to Woodcraft twice to see what might be going on and they have no idea why it won’t cut pins and tails accurately. The aluminum one-pass template for making drawer boxes flexes when you tighten it down. No reply from PC on inquiries about this issue.

All in all it was a waste of money in my opinion. I won’t sell it to someone else because I wouldn’t feel right charging someone money for a great idea but POOR execution of a jig/tool. Now I’m stuck with a $500 setup that won’t work. Very disappointing to say the least.

There is a supplemental instruction manual that tells how to dovetail boards longer than 12 inches.

I’ve had mine for several years and after taking the time to practice and find out the cause and effect of the various adjustments, found out that it’s not that hard to use.

Here is the link to the supplemental manual: http://www.rockler.com/tech/RTD10000211AA.pdf

Milo,
I use a Leigh jig, but it is probably applicable to your set up. The trick I use to get tight joints on a through dovetail is to set up two routers (one for pins and one for tails). Two routers take some of the frustration out of having to switch between your dovetail and straight bit in the middle of the job. Do practice cuts with boards that are of the same exact thickness as your good pieces. Cut the pins and tails off the scrap and try again until you get the fit your satisfied with. Don’t go to the good stuff until you’re dialed in on the scrap.

As RZH says, exact thickness. Don’t even depend on the dimensioned S4S boards you may have purchased for these boxes. Run every piece through the same thicknessing process, including your scrap pieces used to set the router(s) up. Otherwise, you WILL end up with ugly, loose and/or tight pins and tails. BTDT.

Thanks, ajosephg for the link to the manual! It has more than the standard(?) manual that came with my PC dovetail jig.

RZH,

I am planning on using recovered antique pine for the boxes, so I will be planing all the wood down together before I start. Hopefully this will take care you this problem?

Milo – That’s how I do it. Make sure you plane a couple extras for practice and screw-ups.
