Where do you guys buy tapered reamers? I was a little surprised by the costs I was finding when I started to look them up online. Up until now I have not been reaming a tapered or flared hole for peining, just a straight hole. I'm starting to pay attention to the little details now, and I want to do this right.

The sizes I'm looking for are #7/0 (for 1/16th inch pins) and #3/0 (for 1/8th inch pins).

So where do you guys get them? What's a reasonable price range? How quickly do you burn through them?

Thanks guys!
 
I'd check MSC Direct, probably your best price. I doubt, unless you're pumping out 100 knives a year, that you'll wear one out for quite some time. Especially if you're just using them on mild materials. I'd say $20 - $30 for a good one.
 
Enco has them cheap as I can find or have found, the carbide reamers are on sale this month as well. 1/8" for $14.95 or hss for $5. Just got mine from UPS today, but they were not on sale when I ordered them:grumpy:
 
I use tapered solid carbide burs in small sizes from Supergrit and turning them by hand I doubt if I'll ever wear one out. On my slipjoint bolsters its important that my pins don't show and since I've been using the x-mas tree burrs -no problem.
 
Hand turned reamers? I thought those were just for wood! I assumed I would have to run these in the drill press. Do you put the bolster in a vice or can you hold on to it and just crank it? As always guys, your help is much appreciated.
 
I've just used t-handled tapered hand reamers. I use it for handles and bolsters. I'm new to knifemaking, but the few bolsters I've done so far seem rock solid.. annealed stainless brass, ns, etc. are pretty easy to cut into.

Technically these are not reamers but they will work just as well and you can make them your self for a couple of bucks.

If you are using 3/32 pin stock, grab an old 1/8 drill bit and grind a long taper the whole length of the shank.(I take mine down to a point) Next stick the fluted section into a short piece of 1/2" dowel which will be your handle.

Finally buff the hell out of the tapered section and you are ready to ream. Rather than remove metal you will swage your taper in. Try it and you will be surprised how easy and effective this little tool can be, or you can spend $20:D

If I'm getting this right, your asking about flaring hollow pins (tubular)? Someone brought up the idea about using ball bearings to pean in the flair. I'm trying to find some myself to try this.

Pretty sure he was asking about solid pins... I really only use tube for thong hole liners, so I just epoxy..pressure fitted a few too. I've heard of the ball bearing idea.. just haven't tried it. I've seen a lot of flared tubes come out pretty sloppy looking... guess I'm just avoiding that for now.
 
I haven't needed it very often, but I picked up from Don Robinson over on knet to use the tip of a common hardware store spade bit (in a drill press).

Take care, Craig
