I got my punch set from the dallor store in the scrapebooking section , has 8 different sizes from small to large and works just fine for me . For really , really small iteams I made my own from brass tubing . Sometimes you don't have to spend a lot to get the best results .



you got me to thinking when you mentioned brass tubing. i dug thru my electronics junk and found a box of what are called pogo pins. they are brass pins that are spring loaded and have a contact on a plunger mechanism. some can be soldered to directly with a wire and some slide into a brass socket that is wired. i had about a dozen sizes and several styles. i tried them out and they work quite well for punches. a plus is that the tail to solder wire onto is shaped like the tool made from brass tubing that was featured in an article here on how to make scratch scale weld beads. so, it was a double score! (although i think that the weld beads on a decal sheet would be the way to go... )

thanks for the spark that ignited a brain storm!

Hi there

Have you any photos of these pogo pins, how you used them to punch the holes, and the size of the holes and circle pieces you can get compared to something like a figure, vehicle, etc to see what you can achieve?

Hi! I misplaced the charger for my camera so until I find it I can't take photos. However, here is a site that sells them and has many varieties.

http://www.idinet.com/PS/general.aspx

If you look at them you see they resemble a small hydraulic or pneumatic cylinder in that the contact is attached to the end of a rod. The rod is spring loaded so that it can be pushed back into the base. I have pulled the contact part out of the base. A bit of clean of clean up on the edge and what remains is a brass- probably a brass alloy - tube that is very thin walled but pretty hard, I just tap the closed end (which is usually blunt) with a small hammer to use the open end as a punch. But if you look at the various contact surfaces there are interesting possibilities for texturing and surface anomaly creation. I'm sure even the brass bodies could lend themselves to other creative endeavors. The contact and rod it is attached to also has possibilities as a pin punch, etc.

Many of these pins finger press fit into a cylindrical recepticle that is also a tube shape of the same material. The difference is they have a smaller short cylindrical "nipple" for lack of a better term on the opposite end for connecting a wire or other conductor to via solder. This nipple has about 2/3 rds of one side of it trimmed off and nicely beveled so you can lay the wire in it and touch the top of the wire with your soldering gun tip while the bottom lays the stripped length against a solid surface for good contact. It is the shape of this nipple that matches the tool tip profile fabricated out of brass tubing that was used to create scratch weld seams in another "how to" article I read here some where.

The lengths I have used range from about an inch to two inches total. Diameters i have worked with have been as small as maybe 1 or 2 MM at the contact shaft. Again, this is a recent idea for me to use these in model building. my previous experience with them is in electronics work. my preliminary testing shows they work. Some applications may require a handle but a razor saw handle or medium or larger pin vise would work.

Costs run dependent on quantity, and really seems to vary from company to company but they aren't very costly either way. Just enter Pogo Pin into Google and hunt around.

Please post back and let me know what you find and if you try them, please post how they worked for you.

The issue seems to be finding punches that are small enough (at least for 1/35th scale builders). A one inch bolt head has to be smaller than 1/32 of an inch! Those are not so easy to find and so delicate, you hate to breath when using them.



For my needs, larger is better. I needed the larger punches for the large washers found on most Modern US armor upgrades, ie, Bradley, Stryker...
For smaller bolt head I have a lifetime supply of Bradley side armor plates. Much better than PE in my opinion, as PE doesn;t have the proper height ratio. Evergreen hex rod, which I have used, can be hard for some folks to cut squarely. The ones I shave off of the kit pieces are always square, and have the right thickness.

That's cool.

.... however, If I still want to order a Waldron (Roll) punch and die set, does anyone have a clue where I can source one? I ordered one through Great Models and they sent me notice that is was out of stock. I then learned that Waldron was out of production (though supposedly soon to be picked up by Roll).

Cheers,
Fred

Roll Models picked up Waldron about a year or more ago.....hit them up on their website, and I am sure John can hook you up!

Thanks,

I just ordered a Waldron punch set this morning from them. I really look forward to playing with it. Never mind creating discs to fill punch marks, or making rivets, the chance to really dress up instrument panels will be a blast.

Cheers,
Fred

Hi Frederick,

I was wondering if you received your Waldron set (which set is it by the way ?) and if you like it. I've been meaning to order one of them for years and never did for one reason or another. This thread has woken me up on this again and so I wanted to know if these sets are as good as some say they are.

Thanks,

Rob

Yup,

I got the 6 piece (.039-.160) set. I've managed to punch out some decal instrument dials without any effort at all. I'm pretty pleased so far. My next challenge is to punch out some discs to fill in ejector pin marks on fuselage interior sections.

Cheers,
Fred

I posted some time back in this thread about pogo pins used in electrical and electronic connectors, especially in the automotive field. I finally took some photos of some I have and use. As mentioned, I have used these as punches for thinner material, creating weldseams, adding chipping and surface texture, distressing, and have thought about creating functional shock absorbers. Use some imagination as you look at these.

They come in various tip configurations, lengths, and diameters. Typically wire is soldered into the narrow ends of the holders, the pieces that don't have the plungers. There are 2 types: the round hollow one and the one that is flattened so a wire is laid atop of it and soldered. I have used the latter for a weld seam tool and fabricated a tool from the round ones. I didn't have any of the smaller size of the flattened tail variety handy but you get the idea. The ends of all of them are spring loaded and compress into the bottom part.

I have some that aren't pictured her that the end comes to a sharp point. While probably too long for ammo, they are useful for other things.

Here's an overview of some different types. Socket or holders are on the right:



A concave tip:



The typical diamond pointed tips good for adding chips by dipping in paint and dabbing against a surface, or with a little more force adding texture or distressed areas:





and a small one:



Here's a solid ended one that I think would make a neat scratch build functional shock:



Here are the holders. I have also filed the top part of the narrow round tail off at an angle for an even finer weld seam tool. A slight dressing around the circumference of either round end with a file to make a bevel makes a good punch as long as the material isn't too thick so it takes a lot of striking force to cut through:











I have made handles from both wood and Delrin that fit the holders modified for weld seam tools. They also work well for punch applications as it keeps the striking devive away from fingers! I have also used unmodified holders glued in handles so I could change tips easily. I hope this is useful to some of you.

I just bought some hole punches from Harbor Freight very reasonable



http://www.harborfreight.com

item# 95547
these are an absolute must-have for scratching...



The Harbor Freight puches are great. I picked up a set for $21 with my NRA discount coupon.

Precision Punch has a $30 minimum purchase. Try MicroMark instead. Only $27 plus shipping.

I found this site on plastic punches yesterday. Thought maybe somebody would like a gander at it as prices might be cheaper then the Hobby related ones. You know the $80.00 and $90.00 sets. I see the same punches that come with Waldron set. All that is needed is to drill your own Pelxiglass piece and the metal plate.

Look under pins and punches! as site won't open to page one of those html things

Just found the following hexagonal punch sets, which would be the one to go with? Any others out there for a reasonable price?
