B-Square Scope Mount Jig - Instructions?

[wkdickinson]

I just bought a used B-Square Scope Mount Drilling fixture from a guy on ebay. All I got was the fixture and some parts, no instructions. I thought it would be self-explanatory - it's not, at least for me. Does anyone on this forum have a set of instructions that you would be willing to scan and post of PM to me? I am not a gunsmith in any sense of the term, just a shooter and hobbyist. Some years ago I bought a partially "sporterized" Mauser 98K (1945) with the intention of finishing it. With COVID it seems like a good time to make that happen.

I've found some pictures on the internet and I think I have actually figured out how this works, at least on a Mauser 98. But there are a couple other things in the stuff I got that I have no idea what they are for. So If someone has some instructions, I sure would appreciate a copy.

For those of you who are interested. I figured out how the B-Square fixture worked, drilled and tapped my Mauser 98K receiver. It worked perfectly! I got a #31 drilling bushing with it and drilled the receiver with just a freshly sharpened #31 twist drill bit. I got lucky apparently, mine wasn't "harder than the hubs of hell" as noted by many and using "Tap Magic" and a slow but steady pressure, the bit walked right on down through the receiver.

Likewise, I made a "tapping" bushing, bought new 6-48 taper tap and had no issue whatsoever tapping the 3 holes.

There is lots written about this fixture not working well and subsequently being discontinued by B-Square and Wheeler. I don't think that was the case. I think what happened was that as things evolved, old, war surplus actions became less and less available. Consequently, the market for these fixtures dried up and ultimately B-Square and Wheeler, just quite making them.

Mine sure worked good!

What does it do that a mill doesnt do?

Cost $4000.00?

LOL, probably nothing, but I only paid $65 for the fixture and it took about 20 minutes to setup, drill and tap the the 3 holes. More importantly, I don't have a mill and I don't pretend to be a gunsmith, just a shooter who enjoys working on his own guns.
