I came home yesterday to find a box from Jack Huntington. He completed the gripframe much faster than expected. I’ll spare you the obvious adjectives which describe his work. If you’ve ever considered his reshape, do it. He has done BFRs, XR3-REDs, and this Bisley for me. Nothing fits my hand better than his contouring and grips. The 505 LFN mold also arrived from Mountain. It was on my doorstep less than 2 weeks from when I placed the order. You’re hard pressed to find better service. -Lee www.singleactions.com"Chasing perfection five shots at a time" Those grip frame/grips are gorgeous!

Not sure if I've already commented or not, but I was thinking the same thing. The pictures on this build are awesome, can't seem to get enough.

Thanks again Lee for including us in this. I've got my eye on that mould! Did you have it designed to drop .513 505gr with Linotype? I seem to remember that you normally cast with Lino.

Thank you for sharing, as someone with little to no experience in proper machining I find these very interesting.

One question why heat treat THEN hone out hole? Could it possibly change during heat treating?

One question why heat treat THEN hone out hole? Could it possibly change during heat treating? Oil quenching during the heat treatment phase creates some scale. This has to be honed out. -Lee www.singleactions.com"Chasing perfection five shots at a time"

A large wheel cutter is how we ‘gear’ the ratchet. But we can’t do a straight cut; the geometry dictates these be offset 20 degrees to the rear plane. The indexing head is canted 20 degrees out from the x-axis. The mandrel is reinserted in the basepin hole and the cutter is brought up to touch the bottom edge. Drop the table 0.090". Now here’s the trick to timing the ratchet relative to the notches. Dividing heads have a 40:1 ratio between handle rotation and spindle rotation. Turn the handle 40 times and the spindle moves 360 degrees. Hence, one turn equals 9 degrees. The ratchet's teeth have to be offset within a narrow range of degrees from the position of the bolt stop. Our indexing head is rotated 1 and 24/57 turns (~12.8). The cutter is zeroed on the back edge of the ratchet. IMPORTANT – the zeroing occurs on the outer most edge of the circumference. Once that’s done, the wheel is fed into a depth of 0.060”. To cut the next cog, the indexing head is turned 8 rotations. This is one of the most precarious steps in making a cylinder. If the ratchet depth and position relative to the notches are off, we’re screwed. An error here sends it to the scrap pile. We're not quite done with the ratchet. Next time, I’ll mill relief cuts in between the cogs. -Lee www.singleactions.com"Chasing perfection five shots at a time"
