Am I understanding the Incra jig correctly?
So, I'm breaking in my dad's incra jig fence system. I would like to make through dove tails on 1/2" stock for a set of drawers. After reading and doing a few experiments, I discovered that the equipment I have cannot make that joint. Best I could do is through dove tails on 1/4" stock. (I have a 14 degree bit that is 1/2" wide and 1/2" tall.
I called Incra and was told that I need to buy the "The INCRA Master Reference Guide with Templates" book because it contains several templates for 1/2" stock.
My question is this. I can figure out the spacing the Incra needs to move for each cut, and lay out my own template in CAD. Am I correct in thinking that the cutting area on the bit needs to me twice the thickness of your wood?
Also, in an old posting here someone posted a link of a program that layed out templates for you. The link is dead. Does anyone have that program by any chance?
Thanks,
Dean

Hi Dean,
No, the width of cut of the bit does not need to be twice the width of the stock. Your problem is that you are using a 14 degree bit that does not have the depth of cut necessary for 1/2" stock; you could cut through dovetails in 1/2" stock with a 10 degree bit because it has a greater depth of cut. The Master Reference Guide suggests a maximum stock thickness of 3/8" for through dovetails using a 1/2" 14 degree bit although you could possibly stretch this to 7/16".
The Master Reference Guide and Template Library is a good investment as the subject is rather more confusing than you originally think it will be (although that could just be me?) I have an Excel file titled 'Incra Calculator' that may be the 'program' you are referring to. I am quite happy to supply you with a copy by email if you PM me. I also have some other resources that you may find helpful.
Once you get your head around using the jig you can really produce some fabulous projects, but, it is certainly not as easy as they make it look in the demo videos (of course, that could just be me again?)
Regards,
David

I think that could be helpful,IV'E just bought a INCRA from America and I'm a devil of a job getting it all to line up,
the guide base seems to have a life of it's own and wont stay straight meaning the fence is skew-wif ,must be me,I'll keep going and try to sort it out,it all looks so easy in the demos, boy did it fool me, MAC.

Agreed, with the "Fence won't stay straight" and what's with the piddly nuts that slot into the channel under the cursor box. Over tighten them once and they just spin. I'm changing mine out for the little elongated feet that fit in the slots properly. In the end I set up a laptop to play the DVD in the shed and followed each step exactly. I think that's the way to go. I am now starting to get the hang of it. For a while there I was trying to use the Master book with metric templates
