I,m looking for one or more of each of the different sized taps used on Winchester models 73,76, 86, 92 and 94 screw holes. Taper taps will be fine as I just want to chase threads when re- assembling rifles.
Brownells has some but not all.
According to Arthur Pirckle's books I would need the following ;
3/16 x 36 Can get from Brownells
6-48 Can get from Brownells
11-36 found supplier but price is prohibitive
4-56 " " " " " "
9/32 x 32 Brownells
12-48 common size
5/32 x 32 found supplier but price prohibitive
1/4 x 30 Brownells

Can someone point me in the right direction ?

Spend the money.

Other than perhaps getting a deal on Ebone, you are stuck paying the price for low volume goods.

Check the local phone books for tool and cutter grinder shops. Some have CNC capability and can grind a tap as required. Might be affordable.

FWIW, you might check on the pitches on the Win threads. They used a couple bastard sizes, like 35 1/2 threads per inch (thirty five and a half). They also used a lot of just-off standard diameters, too. So shown on reprints of various Winchester Drawings I have relating to the Single Shot.

Tried KBC tools?

Try www.taylortool.ca they have in stock, or can make a lot of oddball taps/dies. Prices are very reasonable.

Their delivery time is pretty good too.
 
well, your on the wrong side of the country, but if you were in the calgary area, id say get them from MaCDougal Tool Supply in calgary. he has all the weird sizes. i buy most all the gunsmith / machinest type specialty taps from him. might be worth a phone call anyways. 403-291-2970
he even carrys the brit stuff , BSF
 
"...have that set..." Your next step would be a trip through the Yellow Pages for Tool and Die/machine shop supply places.
"...price is prohibitive..." Unfortunately, any thing that is out of the ordinary costs more. Especially for firearms. Try Epp's though.
Having a tap made will cost a bunch too.

Hi Trev
Re your advice "Spend the Money"--One of the taps is 11-36 @ $109.84 ? And therre are 3 others over $100--- If I was a gunsmith making a living at this thing it would be billed to the job but this is just a hobby to me.
I have all the info on thread pitch & sizes required fro Arthur Pirkles books.
I will try KBC tools . Thanks for the tip .

Owwwww!!

Where were those prices from? Good grief!

You should be looking at about $7 or $8 for good name brand taps, in the standard sizes. The specials, a little more, but not THAT much more fercryininoutloud!:eek:

Re: the "spend the money" comment.
The taps at PA are suitable, barely, for general household chores. Figure out the sizes you want or need, and buy decent brand name taps. I have never had any grief with SKF or Dormer, nor should I, at the cost of them. If you were expecting to get taps in odd sizes, for PA prices, you would be way off. But the prices you are quoting are pretty out there, too. You should not have to spend that kind of money. The internet makes the world a small place, and postage is cheap.
I have crossed paths with a lot of folk that balked at the reasonable prices charged for quality products, because they had seen a "whole set" of similar lower grade tools at places like PA for a fraction of the price.
Whats the saying? The high price is soon forgotten, but poor quality lingers forever. Goes double for small precision cutting tools. At least double.

But paying over the odds can burn too!

One thing that will make life easier, if you are dealing with the tool makers, is to know the decimal size and thread class of the holes you wish to make. I make a number 11 to be nominally .203 inches diameter by calculation (.013"*11+.060) but the thread size of the bolts or screws may be a slight bit off from that. Worth getting sorted out, as it's a tough (though not impossible) job to put metal back in a tapped hole if it comes out over sized and loose as the result of needing a tap that was a little smaller than(or larger) the specific diameter that would be a number 11.
A 2B class thread is a tighter tolerance, but would be more expensive than a 3B class of thread fit, in general. But it may well depend on who makes the tap, and on what equipment.

If you are shopping for taps for scope mounting, I might add, take a look at the carbon steel taps. They will not handle being mistreated and run hot into a hole, but when the time comes that disaster strikes, and a tap breaks off, you can soften a carbon steel tap with heat, then drill it out. Sometimes you can shatter the remains with a solid shot with a punch and hammer, too. Sometimes.

Anyhoo... Hope you get hooked up on what you need.
