410 overshot card punch for sale
2. You need to cut discs of appropriate size. “Hollow Punch” chisels are available at HarborFreight and elsewhere (not at HD or Lowes… checked yesterday when I bought these).
Perfect for application and 28ga; I need a .55-.59 (14 or 15mm) cutter for 20ga though. The 20ga shell I did up above was “firm”, but it’s juuuust in there–I could move it with a screw driver to the side and pop it out. It really needs to be .57-.59″ to sit snugly underneath the roll crimp for 20ga. Here’s a plug cutter that is 5/8″, or .625, that’s just a bit too big but would cut plastic too. You want 9/16 punch or 14 or 15 mm.
Anyways, with a fat 20ga roll crimp (this was my first ever, on Win universal which is thin walled), this would work for 20ga; and certainly works good for 28ga. I’m tired of tool searching so I’ll leave someone else to find a 14 or 15mm hollow punch you can chuck in a drill for the “perfect” 20 OS.
I thought this could be a good thread to list the other parts/tools for making homemade fillers like OS cards, wad inserts of felt and thick cardboard. Here’s the ideas I’ve read or come up with:
Here’s a link to larger hollow punch, it has 9/16 (.56″) and 5/8 (.625). The 9/16 should work for 20ga OS while the 5/8 for 20ga nitrocards (used for 12ga load spacers).
Hobby Lobby claimed to have a “Large hole punch set” for $7 with 5/8″ size… but this was a goose chase, she fibbed to me on the phone, it was just 8mm.
I ordered the 15mm hollow punch chisel from ebay I listed up above. It was $4.39. It shipped from China and arrived in less than 2 weeks. It looks good and is decent quality.
For the other punches listed up above, after hammering out 100 cork discs or so on a piece of pine, it seems to me the cutting edge is getting dull on the 1/2″ one.
For the plastic OS discs, you need to chuck the cutter, (rotating plug cutter or drill type hollow punch shown above) into a drill, my drill press will accept the 1/2″ punch and use it as a drill too.
I got an idea on the internet from a post by guy named “BT Justice” of a way to hold the punches if they don’t chuck in your drill– use a shotgun hull with a bolt through the primer hole to chuck into the drill, and then shove the punch into the end of the hull to hold it. I know BT has indicated he’s been miffed when ideas aren’t given proper attribution, so want to be sure I do mention– that was his idea. Using a punch set to make wad fillers is of course an idea that hundreds of folks have thought up, besides me, on the internet. BT made a post back in 2011 apparently talking about using meat tray styrofoam as a wad filler, so I hereby give full credit to all concepts about using a punch with a meat-tray to him! I got the punch set idea from Cerberus on ShotGunWorld though.
A great guy who goes by the moniker “lostknife4” produces some beautiful looking roll-crimped shells, and puts a nice round label over the OS card. A lot of folks liked it, and here’s what Lost said about how he made the labels:
Not sure if anyone would be interested or not, but a while ago I got sick of being told my LGS was out of "specialty" shotgun components (non-resin wads, filler wads, cushion wads, overshot cards) so I decided to make a press-mounted tool to produce my own.
I"ve had a lot of inquiries about similar tools for 20G and .410; I doubt there"d be enough demand for me to make something in those, however if you know of anything similar please let me know so I can refer folks.
