Well it's been a while, but I've finally taken the time to continue this project.
Phase 2 of this project was to arrange some sort of front support - the ultimate goal is to have this rifle in a deer hunting cache. This support would need to be able to pivot in all directions. That got me thinking quite a bit. Mostly over the past month. Again, this is a project on a budget, so... machining would need to be kept to a minimum (i.e. mostly my free limited skills).
A trip to Princess Auto yielded a big swiveling caster wheel. Turned upside down, and with the wheel removed, it looks like sonething which could hold a rifle
Then, it was only a matter of attaching the rifle to this support... This is where it got interesting.
Here's the underside of the Tapco stock:
Yup, I know some plastic stocks have a rail instead of a bayonet groove... but I decided to stick with this stock rather than buying and modifying another one. Also, another issue I thought about at that point was that, if I attached the stock to the support with no buffer of any sort, recoil would affect the flimsy front part of the stock, it would try to tear itself off from the support. Hmm, more food for thought.
So! I decided to make:
1. Something a bit more solid on the stock, to attach the support
2. Something which would reduce (in theory) the recoil impact on the front part of the stock.
Here is what I did to offer something to attach the support to the stock: One "V" shaped rod, going in the bayonet groove, and one rod going in the stock, to which the "V" rod will be attached.
Then, this I had a lot of fun doing: the Super Duper Recoil Buffer System.
I used a rectangular section of steel, in which I welded four stubs, or short pieces of rod. These to hold the four springs in place. Between the springs would go the "sleeve" which was part of the caster wheel. I welded two small angles to attach this strange contraption to the rifle.
So, now the rifle is supported and can move from left and right, up and down.
Step three will be a rail so that the whole assembly can slide from side to side on the cache window sill... Anyone has a deal on industrial linear slides? I can even dream of a curvilinear slide...
