Introduction and some images

Post by SAKO_1984 » Mon Dec 24, 2012 4:46 am

Hi all,
My name is Erik, I'm a mechanical engineer/designer, and a former SAKO M76 owner (two rifles, from 1985 'till about 1995).

Because of my fond memories of those wonderful little rifles I am now trying to reconstruct them in 3D using a professional CAD program.
Not easy without having an actual rifle at hand I can tell you!
Still, I think I've come quite a long way already, as I'd like to show off on this forum with some images:

Large (1920x1200 pixel) versions of these images can be found on my website through these links:

http://www.erikleeman.com/SAKO/HTM/SAKO ... rts_01.htm
http://www.erikleeman.com/SAKO/HTM/SAKO_parts_02.htm
http://www.erikleeman.com/SAKO/HTM/SAKO_parts_01.htm

http://www.erikleeman.com/SAKO/HTM/SAKO ... ure_01.htm
http://www.erikleeman.com/SAKO/HTM/SAKO ... ers_01.htm

This is a work in progress, and I'd sure could use some help to improve things here and there.
Especially some actual dimensions and images of 'hidden' parts would be very welcome!
My SAKOs were mil.spec. (selective fire) 7.62x39's built in 1983 and 1984.
They had milled receivers, and fixed tubular stocks.

Is there any member here that still has such a rifle, and is willing to help me improve my 3D model?

Thanks in advance!

Cheers!

Erik

Erik welcome to the forum. Being a mechanical engineer I can understand your desire to make these drawings of your favorite firearm. We here in the U.S. are the kind of guys who want you to keep working on these drawings to make them exactly correct dimensionally. Yes, we may not be able to buy these from Valmet but we can make them soon on our tabletop 3D metal printers or cnc's! Please let us know how we can help!

If you ever get bored with your rifle, and/or if you really want to know how it works, you can always do this:

Relax, relax, no real rifle was hurt in the making of this image!

A closer look at the cut-away version:

The extractor is missing in this one, so the link to the large version will have to wait 'till I get that fixed.

Cheers!

Thanks guys!

Sure, I could do a poster of any of them, but unfortunately that would take an enormous amount of time. These 1920x1200 pixel images already require about ten to fifteen hours of processing each on my (Intel i7 950, 24GB RAM) computer. Making them large enough for a poster easily doubles that. Problem is that I can't use my PC for anything else during that time; all available cores are used to the max while rendering these images.

Here's another cut-away view:

and of course a larger version:

Again, hope you like it.

Cheers!

Erik that is just awesome! You should start making us lists of dimensions for the receiver you need to make this a working drwing. Here in the U.S we have a guy who can make these. Check out his site
