Transfer Punches

[Randy_]

I've read about them here; but don't know exactly what they are?? Did an Internet search and found some pictures; but they weren't very good and the Grizzly catalog didn't help either. Does anyone have a good picture of one and can you describe what they are used for in the real world?? Thanks.

Fortunately I have not needed to disassemble a pen yet... yeah... I know my time will come!! After running into a nib or two that were a little loose, I have gotten into the habit of gluing in all of my hardware(CA.) Is that a mistake?? Can pens that are put together with CA be disassembled....easily...with difficulty...or not at all?? I don't want a pen from my shop to come apart in the hands of a customer; but I don't want to overkill either?? Anyone have any thoughts??

I always called them punches.
Some one here called them transfer punches.
I did a search under transfer punch at H.F. and the set came up different than the ones I got.
I then did a search under punches and came up with a wide variety.
I tried to post the link but it did not link to the same page.
Go to Harbor Freight and dod a search on "punch"

The most important is get a set that will go through the transmission of a slim line and is long enough to reach the nib.
If they are a little too short there is a way around that.

Transfer punches are a machinist tool. A set consists of a variety of different size steel rods with a small tit or point on one end. If a machinist is making a piece that has screw holes in it and the piece is designed to screw onto another piece he or she uses transfer punches. You would put the piece that has the screw holes, that you want to attach to another piece in the place where it goes. Clamp it down. Select the proper transfer punch to fit the screw holes and put it in one of the holes. Smack it with a hammer and the tit will make a dimple where the screw hole on the base piece should be centered. Move the punch to another hole and repeat. You do that for each screw hole. That gives you an exact center punch dimple to start the drill for the screws.

If the machinist is worth his or her salt, when the holes are drilled and tapped the bolt on piece will fit, all screw holes line up and on to the next project.

As pen turners we find sets of these punches, with a wide variety of sizes, quite handy to disassemble pens that need it. You can find one of the punches that fits just about any situation that you come across in pen blank parts.

Right Mac! One thing about transfer pumches is that the rod is NOT tapered. The working part of the rod is all the same diameter, except for the tip.

I would imagine that if you glue the parts in with CA, they will be quite a bit harder to dis-assemble. Of course, a good rap with a hammer might also break it loose quite easily - interesting question.

If I'm not mistaken , the other name for transfer punch is "pin punch" . Here's a link to Lee Valley's set .

Those are pin punches. Pin punches are used to drive pins in or out of machine parts. Not the same thing as transfer punches.

OK, guys.....thanks!! Now I know a little about transfer punches. I have one more question...... This is from the Harbor Freight web site where they describe their punches:


3/32" to 1/2" punches (by 64ths)
handy 17/32" punch
stand


What's so special about a 17/32" punch??

 

[penhead]

I just got back a little while ago from my local HarborFreight...that set of 28punches is marked 8.99 on the HF shelf...print out a copy of the online price 7.99 and they honor it at the store..

If you do a quick calculation you will find that the set says 3/32" to 1/2". 17/32" is larger than 1/2". If you are drilling clearance holes to use 1/2" bolts to fasten two parts together you would drill holes that are 17/32" dia. so the bolts will slip right through without any interference.

If you drill 17/32" holes for 1/2" bolts and you want to locate the exact place to drill the holes you are going to tap with 1/2" threads that 17/32" punch would be real handy.

What they are telling you is that the set is inclusive of a transfer punch you can use for 1/2" bolts.

And I would add that the discription says "28 peice set". It is by 64ths.

If you do a quick count by 64ths, from 3/32 to 1/2", you will get 26 punches. Add the stand as 1 peice and add the addtional 17/32" punch and you get 28 pcs.

Umm, that is not exactly correct---I just counted my punches and there are 28 punches in the set...the stand doesn't count.

Interesting, I didn't go count my set. 3/32 = 6\64, 1\2 = 32\64. Subtract 6 from 32 and you get 26. Throw in the 17\32 punch and that is 27.

Must be another punch in there some place.
