 Power Custom bolts ship wide at 0.100”. As noted, the frame slot mics 0.096”, the stock bolt is 0.092”. That 0.004” worth of clearance is more tolerance than I like. The new bolt has to be precision ground on a homemade jig. The jig is just a piece of steel with both sides surface ground dead even. Two holes are drilled to affix the bolt so it doesn’t move while grinding. One hole holds the bolt peg, the other is for the cross pin.  The surface grinder I used is a Boyer-Schultz Six-Twelve Deluxe. These are high-end machines and hold to 0.0001”.  The jig is positioned on a magnetic chuck and the bolt is ground until it just fits the frame.  Final width mics 0.0952”, netting 0.0008” total clearance (0.0004” per side – very tight). In the frame - it clears with no drag or side-play.  I also turned the cylinder from 2.0” round stock. This was done on our 15” Nordic lathe. Rough o.d. is 1.86”. This weekend I’ll cut it off, center drill, face, and final turn on a mandrel to 1.80”.   -Lee www.singleactions.com"Chasing perfection five shots at a time" |

Never seen a surface grinder. That's pretty slick!

Lee not to jump the gun but will you address the caliber markings and if so how? Addressed that one a page back. Again, I may re-mark it just to illustrate how we rotary engrave. But personally, I could care less about the caliber designation. I know others do, but I'll never sell this gun. -Lee www.singleactions.com"Chasing perfection five shots at a time" |

Oops. Well, given that description it would be interesting to see the contrasts of things n'er seen before. Gregg – thanks for taking an interest in the process. We actually used to engrave all our cylinders. Most had our name and the caliber wrapped around the rear edge. Here’s a picture with close-up of my .30 Streaker (the other cylinder is in .32-20). It reads "Lee B. Martin III 1993 30 Streaker"    We have two engravers, both rotary bit. This is a picture of our Green model:  The other is a Gorton. These machines create that nice deep, sharp engraving (compared to the shallow inscriptions found with drag bits). For the record, Sig Himmelmann and Forrest Smith used a 50’s vintage Gorton on all of their Sevilles & El Dorados. -Lee www.singleactions.com"Chasing perfection five shots at a time" |

I'm being honest. If I had the tools and the know how, I'd make conversions for myself non-stop. But since I can't, living vicariously through this thread is a joy 😀

 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" |
