Canuck223 Posted February 25, 2012 Share Posted February 25, 2012 I'm trying to design a loading block for my .41 Magnum N Frame speedloaders. Rather than muff it up with poor measurements, I'll ask here. Does anyone have the proper dimentions to reference? I'm trying to find the center of each cylinder bore, it's distance from the center of the cylinder pin, and the distance from c-c across the cylinder. (I know, it's redundant but I like double checking. ) Link to comment Share on other sites More sharing options...
slflr Posted February 25, 2012 Share Posted February 25, 2012 (edited) I'm trying to design a loading block for my .41 Magnum N Frame speedloaders.

Toolguy Posted February 25, 2012 Share Posted February 25, 2012 The center to center (bolt circle diameter) of opposite chambers is 1.088. The center pin to chamber center (bolt circle radius) is .544. The chambers are 60 degrees apart. Center to center of adjacent chambers is .544.

Pete Whyte Posted February 25, 2012 Share Posted February 25, 2012 Remove the cylinder &place it on the material you'll use for your block. use a transfer punch thoough the cylinder holes to center punch the location & drill the holes. Link to comment Share on other sites More sharing options...

That's exactly what I was hoping for. Link to comment Share on other sites More sharing options...
