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.

I apologize for coming to the table late, so to speak, but is there a specific method of setting the headspace on each barrel or will the process become obvious once I get the hardware ready. my understanding with the threaded barrels is that the particular barrel is adjusted by means of the hex at the muzzle. Obviously only the subject barrel is adjusted. I appears to me from your photos that two wedges must be loosened for a particular barrel to be adjusted.Does the adjacent barrel stay in place as it still has one wedge "on the job"?
Gatlings do not have individual barrel headspacing provisions. The entire barrel cluster moves fore and aft with the nuts on each end of the mainshaft. That changes the headspace on all barrels at the same time. This is the reason that attention has to be made to tolerances when making the bolts and the barrel mounting.

Yea Yea YeaI got a picture of your joint
Wow, that was right after the floor was poured, before the machine shop room was framed up. Its come a long ways since then. (about 2-3 years ago I would guess)
Building that pole barn aged me about 20 years LOL

I need supervision. There was a huge auction locally last week, online only. I went with a friend to the preview. The place rebuilds machine tools and is moving.
I bought a Doall vertical bandsaw, 16inch, about 1200lbs for $180. It needs a little luvin but nothing serious.
Also bought a tool and cutter grinder with a weldon air spindle for sharpening endmills. Its 120V and not very big. $50 The air spindle works great and has a full set of collets. The grinder needs a good cleaning and oiling but everything seems to function ok.
Bought a few little items too.
I post this here because I think this is a support group for people with similar issues.

Crossed a BIG waypoint today with the gun project. Successfully detonated a empty cartridge with a live primer. Last pieces made were the cocking mechanism and switch which are working nicely. I still have to make a knob for the rear, probably tomorrow. Also, its past due time to get a crank handle made up, gears and shaft are done, I turned the barrel cluster by hand for the test fire. Still, detonating a live primer renews the enthusiasm on the project. If a primer detonates, you can bet your last dollar a bullet would have came flying out the barrel too! Its now officially a gun, just needing a lot of finishing touches.

Here is a coated aluminum test piece against the real brass housing. Naturally, the camera does not capture such color / lighting details well, it actually matches FAR better than the pic looks.
BTW Polishing then coating the heads of those steel screws to look like brass is in the plan.
