This site, www.woodworkingtalk.com
is the second site I discovered on line that I like. The first site I discovered www.routerforums.com
I also like for all questions relating to routers, tables, jigs etc. There are a couple of guys over there that know a tremendous amount about routers, one has 10,000 plus posts!
So FYI that's that. I did some research after
I bought some Jet DJs on sale for $30 each and found out 2 things. One, the "cheap" jigs only make 1/2 blind dovetails. These include Sears, Jet, Harbor Freight, Midnight Auto Sales...no! Two, the expensive jigs will do both 1/2 blinds and through dovetails, these include Leigh, and Porter Cable Omni jigs.
So, depending on what you want to do with the jigs, like making drawers, the 1/2 blinds are fine although set-up and depth of cut are time consuming to get just right. The templates furnished with these are usually 1/2" and use a 14 degree dovetail bit, FYI. The HOT set-up is to leave a router all set to depth as a dedicated dovetail router. If you can afford that, then that's what I recommend. If not, a set-up gage or block will get you close based on previous successful joints. So, long term get the good ones as they last a lifetime, short term you can get by with a cheap one, but it's limited.
There are some "jigs" that are really templates, free standing, like from www.ptreeusa.com
That you clamp to your workpiece that will make through DTs or you can turn it upside down and use it on your router table. Cost around $300 for a 30" wide unit. Requires 2 bits, with a top bearings. There are many options, so look before you leap!
Just my opinion, bill
PS. Kevin any idea of cost for your jig?
