Garand Gas cylinder

[jimmiroquai]

Hi. Before i embark on the quest for a cheap repro M1 garand gas cylinder fabrication, i'll need to know who would be interested in getting one. And more or less how much your willing to pay for it. So far there are 3 ways to have it done.

1) Casting in zinc then machining
2) Cutting steel tubing to length then welding (very simplified version)
3) CNC machining here or in HK (offered by MAS) = probably most expensive

So i'll need to know how many pieces to have made because this will effect costing.

If successful, i'll have the other metal parts casted/fabricated so that, along with mcshine's wood furniture, we can have garand conversion kits finally available.

I'm interested as long as it's not too expensive

So what would you be willing to spend? As an example, you can get an original gas cylinder on ebay for around 3K without shipping) but you won't find anyone that will ship internationally. So much would you guys be willing to spend on a locally fabricated one?

Hey i found some gas cylinders for international shipping!:

Anyway, an update on the quest for local fabrication. So far none of the companies i've emailed have replied. I could probably go around and visit different foundries but i just don't have the time. I've tried going to 3 different machine shops and all have turned me down saying that the cylinder should be cast or CNC machined. Opoy of MAS has offered to bring a cylinder to HK when he goes to give us an accurate price estimate of having it CNC machined. All else fails, i can go 2ndbat's way and have it casted in resin or plastic.

Not to jump the gun..but i think the resin/plastic option may be the way to go.. to make the cost acceptable for most.

This is the easiest way to go. I can actually do this on my own at home. But i don't know how durable the resin would be.

How about using Epoxy clay ?
a year ago my dad lost the front sight of my M249, so i use a spare G39 front sight and Pioneer brand epoxy clay for metal, i molded it to shape, let it dried, sand it down and painted.... it turn out well and durable

[jimmiroquai]

Actually, i think you can use epoxy clay for the small parts like the front sight. But the gas cylinder will need a lot of work. But it can be done.

Did any of you win the garand gas cylinder?

Here's another option: Shoot&scoot sells the metal parts only (bronze casting) at around 5K php (not including shipping).

More garand cylinders:

This particular seller starts auctions relatively cheap:

I've found a local metal foundry that can cast the smaller metal parts needed for the garand conversion. Unfortunately, the gas cylinder was deemed too large to cast in metal. So here are the options:
1) Have the small metal parts cast in metal and the cylinder in resin
2) Have everything casted in resin (like 2ndbat's)
3) Just buy the parts online

Unfortunately, i don't have the capital to start mass producing these parts. It's not that expensive and the ROI is potentially large, but it's a bit beyond what i'm willing to spend at the moment. (Besides, i just bought a ton of stuff from ebay...again!) So, if any of you want the contact info of the foundry or what to know about casting, just pm me. Incidentally, i've casted parts in resin before so i might be able to help if we go the resin route.

A new hope....Albert's sculptor friend has connections with a large scale foundry. He may be able to help us with the garand metal parts.
