Ok, so yesterday I decided to go forth and begin.
I am following Lobo's checklist with this build, and am very pleased so far. Today the project should take a huge leap forward....
thought I'd try to post some pics for you all to comment and advise on.
It was pretty easy to mount the cart stop to the ORF sideplate. The hole was drilled in the exact location. I am not using a rivit gun or rivit tool yet, but rather my 6 ton bench press to crush the rivits. This is working out very very well. The rivits crush easily and completely fill in all the space of the chamfered holes. You can see in picture one that the rivit mashed fully seated into the chamfer with no additional grinding from me. The outside rivit required a little bit of touchup, but nothing major. It will will finish out nicely.
The trunnion pintle spacer gave me a small amount of problem, simply because the hole in the RSP was not quite large enough for the pintle bolt, nor was it centered exactly. I'm not sure this is a problem with the RSP, or merely some inconsistencies with each gun. I noticed that the pintle spacer on the LSP fit the pintle bolt kind of loose, but the trunnion itself is a tight fit. You can slide it by hand, but it takes a little wiggling. I mounted the RSP, fit the pintle bolt, squared everything up, then drilled the 5 o'clock hole.
I took the gun apart, mounted the spacer, and dropped the long rivit in just to align everything. I noticed that the spacer did not line up with the hole in the RSP. I drilled the 12 and 7 o'clock holes and rivited them with my press. Again, this went breathtakingly smooth, and the fit was very nice and tight. Some light grinding on the outside is all that was needed. I did have to ream out the RSP just a little to allow the pintle bolt to slide through. Also, you can see the great fit the ORF sideplate has with the trunnion by looking closely at the pintle rivit from the inside. It is really a good fit and squares up nicely.
I have put it back together in preparation for doing the eight holes for the bottom/right sideplate, and tope plate.
I do not plan to mount the safety bar. I'm not sure why this was even added as a spent cartridge will hold the bolt open for inspection on the range. I spent 30 years in the Army, and never saw one of these on a .50 or .30.
If I'm boring everyone to death with this let me know, otherwise I'll post more as the project continues.
