Default L7 Nato 105mm gun barrel

I am considering having my machinist friend make up some 105 gun barrels from aluminum tubing stock. I have felt that this is greatly lacking in our hobby and with the Centurian coming its a natural upgrade, as well as those that have the old tamiya leopard 1 etc.

He reviewed my sample that I have and said it would cost about $75 but since he has to make some tooling he needs to make at least 10.
I also requested that the breach end be 2 inches longer than my sample so the user can fit it to their tank project easier and cut to fit their recoil system.
What kind of interest is there in something like this for his cost?
Im not making anything I will just help him out doing the orders. He is retired on a fixed income and makes small projects for people for side money.

If he's doing that on a manual lathe then that's a fairly good price, but if he has access to CNC I would say you should probably cut that price by about half. With CNC the first piece is the only one that you actually have to do any work on, after that it's just running the machine. And I'm not sure why he would have to make tooling, standard indexable grooving inserts and turning inserts should work just fine. And if he's starting from tubing he doesn't even have to worry about the ID at all.

He’s retired working at home on his own equipment. Not CNC.

Nice ideal Rich to bad he could not make with the look of the cooling jacket on it or can that be done by Shapeways with plastic cover .
Thanks

The thermal jacket version would be easy to make with just tubing since there is no taper visible. Just the different diameters and then make the bucks straps.

That's what I thought, but he did such a good job of fitting them together that it almost looks like one solid piece.

I would be in for two possible three. I have a few projects that I would use them on.

He told me $75 each to make them. That would not include any shipping
