Chuck,
Take a look at his links to the Starrett wrenches. The plan you posted is not the type of tap wrench he's looking for.
But thanks for posting the PDF anyway.
I've got a quite an array of Starrett No.93 (A, B, C, & E) and No.91 (A, B, C, & D) and all came off eBay and Craigslist. None cost me more than $40, and there isn't a smoother, better gripping tap wrench made, IMO.
While I admire the will to make some, I don't know if you'd ever be able to make anywhere near the same quality. If you're definitely going to do it, why not just take apart yours and scale it up or down with reverse engineering? If you'd rather have exact dimensions for each, I suppose I could help by taking one (or more of mine apart to give you dimensions.

I've got a nice plan for a 91B from an old SouthBend apprentice projects book
Combined that plan with the Starrett product info, I'll have no trouble making up a nice set of 91's
I'm in Canada
Our used market is pretty dry compared to the US and UK flea market / boot sales
Or you have to drive 3 hours round trip to pick something up and our price of gas is double yours.
Buying Ebay is out because most sales will not ship to Canada and everyting shipped is an additional $40 for shipping and import fees, plus 13% tax on top of the item and the fees.
It makes it impossible to get deals like that.

The ones I own are hardware store crap, none with the separate jaw that makes those good.
I'm surprised they are so expensive. I have four of the Eclipse (UK) equivalent and they often turn up at the shows new or used for a couple of pounds each.

Arbalest, I don't think the ones you pictured are the same as the Starrett ones. The ones you show are 3 piece. The knurled/threaded collar , the body (slit in four pieces up to close to the handle) and the sliding handle. The Starrett ones I own and prefer have 2 separate jaws connected by a spring to cause them to open when the knurled collar is unscrewed.
