Converting Rolling Block
« on: March 26, 2009, 07:07:52 PM »
Hi gents,
Do any of you folks have, or know somebody that has converted A Swedish Rolling Block from Rimfire to Center fire?
I was wondering how complicated it gets redrilling the breach block. Can you reuse the firing pin?
Thanks,

Not being a machinist, I would hire one.  Those breach blocks are hard to replace if it gets screwed up.  If I understand the process, you have to plug the old hole FIRST, otherwise the drill will wander towards the open space.  I'm not sure about reusing the firing pin.  They would be easy to make in any event.

Tubac,

I have converted a No. 1 frame miliatary RRB from rim fire to center fire.

I have drawings that I made for the machinist that did the machine work and will send you a set if you eMail me with your name and mailing address.  My eMail addrerss is wrheller@sbcglobal.net.

This has worked out quite well and I have been shooting this rifle since 1993 with no problems.

Many years ago I converted a .32 cal. #4 rolling block from rimfire to centerfire.  Its pretty straight foreward. Plug the hole, re-drill in the center and make a new pin.

Just did a rolling block last week. Some of the blocks are case hardened and will be hard to get a drill started. Firing pin goes through the block at an angle which makes it a little hard to get it to come out in the right spot. Best to use a vertical mill so a carbide end mill can be used for starting the hole.
