Several slug modification attempts, the road was not easy

kimoleto · « **Reply #81 on:** April 13, 2021, 08:18:04 PM »

Upper punches (usually they form the bottom of the slug) you can make flat bottoms, boattails, concave bases etc

This combination tap holder, thin blades, inside a cylinder die seems to work, last photo is a fired slit slug (30 cal 85 gr 700 fps fired into plasticine), almost fragmented (thats the goal). I´ve been able to progress thanks to a lot of help from US and Mexican airgun/casting/swaging bullets forums. I´m more than happy to share photos and ideas with all of you

Ruben keep it up eventually you will get it down to a perfect science.

Nice work Ruben!

Ruben,
In case I missed it, can you explain how the 'x' blades stay together and in the tap wrench? Do the blades lock together with opposing notches, then go in the wrench or are they individual (4) blades? Does the tap wrench (ingenious usage by the way) 'clamp' the blades in or are they soldered/glued?

Maybe you could post a pic of your shop and what machinery/ tools you might have, it would give everyone a good idea of what can be accomplished when someone puts their mind to something.

I just used the tap holder, no glue. When you tighten the holder the blades stay in place. I tried to braze them but they lose their temper and became to soft. In a 4 blade cutter use 3 blades 1 "big" and 2 smaller ones. I´ve experimenting with a small drill chuck (from a foredom chuck), you get a 3 bladed cutter (bsterne would say odd numbers work better), the chuck seems to hold the blades better than the tap holder

Ruben; I do have one question...
When I see the cut slug in your photo here:

The petals have a little bit of separation; do you close them back up (form them back into their original shape, no gaps between the leaves), or shoot them as-is?
Thanks;
Jesse

I have the idea that shooting them "in the rough" would decreased accuracy, I use the forming die again and its difficult to detect the cut lines. I cant expect a lot from my rifle, the barrel is from a 1903 Springfield, the rifling is perfect but I was told the twist is to fast: gun barrels are imposible to buy in Mexico and can not be legally imported (I tried). Anyway I do have a lot of fun with the condor, is a lot more powerful than spring guns and the slug "development" just adds to the fun

kimoleto · « **Reply #91 on:** April 17, 2021, 01:10:44 PM »

Luge, I use 3 "blades" in the 4 petal cutter, the bigger one is 7.62 mm wide (thats for .30/7.62 cal slugs) it must fit inside the die, the other 2 are around 3.7 mm (sorry its metric your sistem is a mess for me), the tap holder keeps them in position without the need of strange forms in the blades. Be careful slicing the slugs since the cutters are brittle, you have to go straight (thats why I use the press). I´m looking for someone who does silver brazing, that might work or even try to re anneal the cutters once brazed (they loose their temper and become very soft). The slugs you intend to slice must be hollow pointed, a deep cavity is better, it allows you to cut closer to the base.

This is the new 3 blade version (still working on it), its hacksaw steel (thinner steel works better), but I hope the new photos help. The holder is a number 0 jacobs chuck, the blades are rectangular and still need a lot of grinding.

Rubén, 😊
thanks for all your info and pics — I'm starting to think I could try to do something like the method you have been explaining to us — even though I'm far less mechanically gifted than you!

I would certainly a BLAST! (for the trash birds, that is [and well, for me, too 🤣!])

Greetings from Peru! I hope your covid situation in Mexico is a little better than ours here — in a few weeks a good friend will move from Peru to Mexico....

You should try them, its pure fun. I have no experience/training on machining, allways like to try new stuff and this really got me. CoViD situation its difficult in Mexico, not enough vaccines, no real goverment handling of the situation but hopefuly we all get over this.

This thread is almost onto 6 pages and it keep bumping into it! Time to add something...

I'm enjoying following the idea and like most think I might build something sometime. Thanks for the information.

Ruben, your air rifle adventures get more and more interesting...a Springfield barrel on your air rifle? How did you do that?

I realized about 2 pages back that this is something I'll NEVER be able to do.

A great thread to read, though, regardless.

I'm still hoping someone might find a way to "mass produce" these and sell them to GTA members.

I got the rifle barrel from a friend (I have some Cristera war era Mexican Mausers in my collection so we had a lot of things in common), my lathe is to small for the barrel so I took it to another friend (with a bigger lathe), who took away the chamber and cut the barrel to diameter (the thin part for the condor, in spanish is called "el popote" the straw), it was really simple. I modified the valve making it bigger, never reached the velocity numbers claimed by others but it OK for me 650 - 800 fps with 95 - 45 gr bullets. One of these days I´ll buy a 4500 psi rated air tank who knows... Then I read about talon slugs and was really impressed thats how the search started

Wow Ruben those fragmented-cut bullets look Awesome👍🏼

I especially liked the three slotted one🎉🪅🎊

kimoleto · « **Reply #99 on:** April 18, 2021, 09:14:49 PM »

3 blade cutter also works, even tried on .30 and .40 cal pellets, they need more support than a slug (they collapsed) but with some patience can be sliced too. as you can see the blades move sometimes, I need some brazing to support them 8as suggested by luge), the cuts were made without a die and the blades are still untrimmed.
