Sniper mount steel question

[Kov1985]

Hello everyone,

For a long while now I have had plans to build myself a copy of a Canadian no.4t sniper with the TP mounts and Lyman Alaskan scope. With the help of an absolute legend I met on this forum, who happened to own one, and from the other side of the world, I was able to draw up plans with dimensions of the thing.

The lower part that screws to the receiver should be pretty straight forward. The upper component though has been giving me nightmares on how I’m going to do this. To machine that component out of a block of steel is no small task. Well beyond my skill and would require jigs to build the actual jigs to build the thing.

Just recently though it’s dawned on me, perhaps I can commit said design to CAD file, and get it casted out of steel. Machine it from there. It looks as though that was how they were made originally anyway.

Is there anyone here who knows what kind of steel these mounts casted of originally? Mid carbon steel do the trick? Low carbon? Iron? What are the normal no4 T mounts made of? Is it a bad idea and why? And more importantly, has someone already done this to save me the trouble?

I still for life of me can’t believe no repro company makes this mount. And I’ve contacted a few of them, they will not build it. Must because I want it. To me it’s a better design and I don’t have to torment myself with all the drama surrounding the no.32 scope, real or fake.

Thanks for your time.
