Disagree. Not that sort of precision with a round attachment on a straight surface. Instead (1) sharp files with, as donw said a steady hand, followed by sandpaper-wrapped needle files, also with a steady hand.
I hate to disagree with you, but that's how I do all the ones that I get in the shop that have a sharp edge.Not this.
Dr. Bob... no offense but you do this for a living. Probably have messed up parts learning too. Arm chair gunsmiths would do this, mess something up, then blame the part and bad mouth it.I hate to disagree with you, but that's how I do all the ones that I get in the shop that have a sharp edge.
I have a carbide engraving bit that I put in my die grinder, give it a nice edge break and then switch to a pink chainsaw sharpening stone to smooth it out so it is nice and even.
Once that is done, I put in an MX 1/4 X 1/2 inch bit and polish the grind marks from the sharpening stone and final polish it with a felt bob and some 555.
I've done this a few times so I have had practice though. A very steady couple of hands (I don't put it in a vice) and you would be surprised what the results can be had.
I just wanted to throw that out there. I'll try to get some pics for you to see and post them.
I use the carbide cutter to get the bevel started, but it's not a smooth and equidistant champfer, so that's why I switch to the chainsaw sharpening stone. This evens up the profile so it's all nice and neat. The MX does wear fast, especially around the serrations so the previous tools are used. All I do is use the MX to buff out the grinding marks left by the stone. The final felt bob is to give it that nice luster that the CNC profiling tool like Cylinder and Slide turns out.You might use the Cratex as part of the finish process, but would be very slow and would lose a lot of points if that was all you used. Cratex breaks done quickly on edges and would be difficult to maintain a shape also. Small files and time.
Oh, no offense taken - I'd never get offended for somebody remarking like that. You drive a sincere point. As I said just a few lines ago, I'll try to see if I can get a hammer out and do some pictures for you all to see. Maybe this will help some of you and give some alternatives or ideas for a process that works for those that are interested.Dr. Bob... no offense but you do this for a living.
