Let’s talk about roll crimpers!

That 4 pin roll crimp is perfect!

I have an antique hand crank that looks like the Lyman version. Problem is it will only fold over the crimp about 1/16".

Right now I need to find some pulleys to slow down my drill press. Or do you guys think a veriac would work? vfd's are way to expensive.

If you have and old Lyman hand crank roll crimper, the new style crimp head will fit. None of the pictures I posted were produce on a drill press, most all of them were made this the tool shown below.

I took my BPI single pin today and added 2 more pins. It really works good now.

Care to share how you added pins?

Excellent ! I was going to ask why not add pins...

A veriac should work as you don't need full power for intended use.

I just use the cheap $16.00 roll crimpers off of e-bay from Russia. They have worked for thousands of rounds in my 12 and 16 gauge guns.

Do they work equally well with paper or plastic hulls?

Nope, variac will not work on a capacitor start motor. Has to have brushes like a hand drill motor.

As to the pins. I used drill rod I use for punches. You locate where it needs to be drilled and drill a hole through the outside then into the center piece. Make sure the hole you drill is a couple thousands smaller than your pin. Tap in the pin. Then I took a punch and peened over the outside edge of the hole to prevent the pin from backing out.

i use the Precision Reloading metal 4 ramp roll crimper on my drill press at 600 rpm's without any problem. Most any drill press speed will work within reason as its all about the dwell time. When starting out the crimper is cold so more time needs spent toughing the hull mouth to warm the plastic and a slower crimp speed is needed to fold the roll. After 10 to 15 roll crimps the crimp tool is almost to hot to touch so very little time is needed to warm the hull mouth and it's a fast push on the drill press handle to form the roll crimp. I have heated the roll crimp tool but find by just moving slow for the first 5 or so crimps the tool gets enough heat without the hassle of using the heat gun on it.

A month or so ago I ordered the BPI 4 pin crimper but after using it on a half dozen hulls I decided I really didn't like the wide flat edge it left so I sent it back. My main issue for trying the BPI was I wanted a little more taper on the end of the shell then I am getting from the Precision crimper. I ended up setting up one of my unused Mec 650's for 3" and adjusted the final taper crimp die to give me the taper I was looking for.
