Hey kids-
I’ll be trying my hand at sliding dovetails (tapered) for the first time, and I’m wondering if anyone has any advice on dimensions of the dovetail in relation to the thickness of the stock, router bit diameters and angles, etc…
I’ll be joining stock that is 1 1/4″ thick (finished) and since the piece doesn’t have sides or a back (contemporary piece) I am assuming a greater angle (14 deg) will offer better holding power, as well as racking resistance.
I have a lot of text on the subject, but I’ve found nothing on the points listed above. Is it simply to use the largest bit possible to accomplish the cut? Or would a smaller bit and multiple passes give a better result?
Does this all make sense???? Help!!

If you're using a sliding dovetail to hold an object or piece in motion or that carries considerable weight, a wider angle of 14* is not necessarily the best approach. The wider the flared angle, the more stress on the narrow angle. I would stick with a traditional 7-10 degrees.
Very good point; I hadn't thought about the narrow part and the stresses it would incur. Thanks for the advice.
Not all the answers, but likely to answer some of your questions.
Pat,
I really liked your book. It's a great reference for all router based applications.
Routerman, thanks for the link. That actually has a ton of useful information that answers many of my questions exactly. Super helpful... Thanks again!
Mtn,
This article has a couple of the answers you're looking for:

This one has some tapered sliding DT pics and techniques toward the bottom:

This may or may not be of any use (I didn't go all the way thru it...)

Hope that some of this is of use to you.

Thanks James. I've been eyeing some similar plans to the Shaker wall unit, and when I get a second to breathe I think I'll get on it...

Why use a tapered sliding dovetail as opposed to a regular one? Seems like an excercise in extravagence...
Not sure I would call it extravagant... From what I gather you'd have better luck breeding an elephant to a pig than getting a 16" sliding dovetail together. Actually, according to many the tapered sliding dovetail is vastly under-utilized, more practical in some cases than a traditional sliding dovetail, and not much more complicated to construct.
It is merely an option at this point; just wanted a little more feedback as to the dimensioning of said dovetail, and some advice on bits, etc.
Thanks,
JM

Very, very true!!!
I've built several items with "straight" sliding dovetails. That is a misnomer! They don't "slide" after the first 3"!Then I found out about tapered, sliding dovetail. What a dream. They slip in (at least all of mine did) up till the last few inches, after which they drive home for a snug fit over the full length.Jerry
A while back I posted a description and some photos of the procedure I fiollowed from a Taunton/Lonnie Bird book. To view this look up message # 1250.11.Jerry
Thanks everyone for all the advice and feedback. I've got a little more reading and thinking to do.
Have a great weekend!
Does this all make sense???? Help!!
Yes it do! I make them all the time... First off.. I just put some glue in the 'grove' .. sort of in the center.. AND hammer away!
DO NOT use glue ALL along the slot! MY Opinion only!
