I am a machinist with 60 years experience in the trade who started a couple of guns 3 years ago. With my machining experience I decided I didn't like the idea
of silver soldering or welding these parts together. I used dowel pins and screws instead. I have disasembled these guns at least 100 times in the last three years
to re-work, modify, tweak, or re-engineer the parts to make the gun work. I couldn't have done that with a soldered up gun.
Just food for thought.

I added a Enco 6 by 12 surface grinder to my shop. I sure wish I would have done this (cheap) addition way sooner. I was told it had only a few hours on it. I took a few pieces off to clean it, looked good on the bottom sides! It sure makes a neat finish on parts! I can think of a lot of uses for this machine. Came with the magnetic chuck too
Last pic is just a test part, before I got the diamond dresser for the wheel.

Not machining but material related.
As we all know, brass costs have gotten totally out of hand. I have been considering alternatives that would look like brass.
About a month ago, I bought a Harbor Freight powder coating system, $60 with coupon. My main idea was to powdercoat the metal pieces of the tripod when the time comes, probably in black. Well, I got to looking and there are 6500 colors/types available from just one vendor (prismatic powders). They have a "tinted" clearcoat brass that is intended to go either over a chrome color base OR bare polished metal. I ordered some and today gave it a try.
I took a scrap of aluminum about 1x4 , polished it up and coated it. After the usual baking at 400 deg I was amazed at how much it looks like brass. How close does it look?????? The aluminum coated piece laid up against my real brass housing matches about as identical as you could ask for !! Its amazing !! I would say that with real and a coated piece on the table in front of you, standing, you couldn't tell which is which.
I am inside now but will try and get some pics tomorrow. Don't know how well pics will do justice to such comparisions but will give it a try.
Here is a link to the product. https://www.prismati...ASABEgLKe_D_BwE
AND a couple pictures from their website that I would say is a real good representation.

This pic was taken yesterday 01/09/16. 1874 Camel in .45-70 nearing completion. I still have the feed hopper to machine. This is the last major part of the gun to be done. Gear blanks are at the gear cutting shop and should be done in a couple of weeks. After the gun is done I'll start on the tripod parts.

Got the tripod finished up. Few cosmetic pieces needed yet but the end is in sight. I have the bruce feed mag drawn up in fusion 360 and that will have to be made/tested soon. I am going to do the bruce feed with 3 columns, 100 rounds is the goal. I have a bit over a hundred rounds through the gun and it functions beautifully.
Got a little thimble piece to make for the elevating mechanism BUT my cnc lathe failed to home a few weeks ago when I was about to make it. Turns out the index pulse on the encoder went bad. The encoder was $348 from the original supplier but I found a identical one on aliexpress for $50 which I ordered. It took 3 weeks from China but its all installed and the lathe is back in operation. That thimble will probably be the next piece to make.
Been thinking about making one of those medallions discussed earlier in this thread. New territory for me.
