Just ran a bunch of SW Shield aluminum magazine floor plates on my CNC mill.

Wondering what other cheap plastic parts might be popular to replace with honest metal?
Does not even have to be firearm related but does need to be something that is needed in decent volume.

My machines sit idle too much, there have to be more parts folk want.

Beltfed 5.56mm upper for a MAC10 along the lines of the now discontinued SABRE.

What about extended mag base plates like These?
USPSA guys use em

Those are patented.

But there must be other mags that need an upgrade, what are they?
With the rush to make so many plastic gun parts there should be a lot of opportunity to offer upgrades.
I'm just a bit out of the loop for the new plastic craze and what is failing.

Refreshing to see someone give a damn about a patent.

What are your machining capacities?  What is standing still that needs work?

Cincinnati Milacron 208U CNC Chucking lathe.

Matsuura MC 1000V Vertical mill, thirty station BT45 tooling.
It's a pretty big open-bed machine so can handle larger parts than most of the machines in this area.
So of course it's mostly used to make very small parts.

Aratron 300 Sinker EDM

So I can turn, mill, and burn.

All older equipment so I'm not claiming to "Hold tenth's".
But I've made some pretty complex parts with no problems.

Ah the 1000v.  Twice the fun in one package.

Good for small parts as long as you have at least 4 double vises - and the parts are 718 inconel or Titanium.  Those 4500 rpm spindles are not the best for 3/32 end mills in aluminum.  Still a very nice machine for heavier work though.

Are you in Clark County?  I know a couple of people that farm out some work here.  One job is 4" OD x 7" long chucker work...

I figured they were patented, whats the deal with a patent....it's gotta be how much different?

I'm in Gardnerville, fifty miles south of Reno, fifteen east of Lake Tahoe.

The Matsuura is a single spindle machine.
For small parts and small cutters I have a speeder head.
Works great for engraving too.
I also have a right-angle head but I've never actually found a job that needed it.

As to working around patents I have reason to appreciate the work that goes into developing your own product.

Going to the gun show this weekend for two purposes.
Show off my products, and look around for ideas on craptastic parts that need replaced with metal.
There are probably more magazine bottoms in need of replacement, should be other parts too.

4" OD x 7" long type chucker work would be great.
Certainly easier than gun barrels.
But shipping cost probably make that impractical.

Yeah, the freight on all of that ductile iron would be a deal breaker.   i will keep an eye out for you on parts.

Never saw the single spindle version of that machine.  Would make an awesome unit for big work.  Be glad you have never needed the right angle head.

I've made several of these for 10/22s.
This one is on an RAR.
I usually make them from aluminum, but thought I'd give brass a try on this one.
The guys over at Rimfire Central are always bitching about the mag catches on Rugers, so there might be a market.
I make them with a hacksaw and file, so I won't be any competition if you decide to give it a shot.

Are you saying the Ruger 10-22 mag catches are originally PLASTIC?
I thought Ruger had higher standards.
Of course it's another tiny part for my big machine.
Definitely would want some gang tooling for those.

Don't you make the De Lisle replicas?

Yes, but they are a niche item that only sell a few per year.
Looking to keep the machines running many more hour$.

Got pics of the shield base plates?  Price? Interested.

Current production Beretta 92's have plastic bits that need replacing, but there may be some already on the market.  The CX4 line is the same.

Unsure what the market for them is though.

Richard,

I need a plastic part replaced for a pistol. It is a plastic washer about the size of a quarter.

If I mail you the broken part (if I can find it) what would you charge me to make a replacement?

TIA.

Steel or aluminum?
Seems too simple, is it also threaded, tapped, etc?
Something I can make several of and sell?

Really need to see it.
Sounds like it would be cheap.

It is round plastic with a countersunk hole drilled through it.

No threads.

It's the rear buffer for an Intratec KG-99.

If it's a buffer it may NEED to be plastic or hard rubber.
Sounds simple enough to make on a manual lathe, send the broken parts and I'll take care of it for you.

Thank you, Richard. It's plastic about an 1/8" x 1 1/2" or 2" if I remember correctly.

The next time I straighten out the safe I'll look for it. I know it's in there somewhere.

When I find it I'll PM you for your address.

Thanks, again.

The mag release on my ruger sr40c is a pile of shit. It sticks every once and a while. The actual spring and latch seem ok but i think with the button being semi soft plastic there's too much friction for it to release cleanly.
