doublegunshop.com - home Forums General Discussion DoubleGun BBS @ doublegunshop.com Fitting hammer castings.

Make a tapered square copper electrode (on any milling machine) and give it to the EDM guys, along with the castings, to drill in about an hour.

Non traditional, I know, but it works.

I suggest this thread be a Stickey. It's so unique that I can see myself needing it in the future. There are several other threads dealing with gunsmithing and refinishing, such as the Barrel and Rust Blue prep threads that would be excellent as Stickeys as well. It would prevent a constant "Rehash" and provide easy access for the new members when they come aboard and ask questions about them. Then, as the threads get older, they wouldn't drop out of the one year Search limitation.

A sub-forum on Repair, Refinishing, and Restoration processes with them (and others) as Stickeys would be even better.

I just thought I should post a picture of a little used device nowadays that is designed for filing in a lathe. Obviously it is known as a �filing Jig� but the down side is that they are not commercially manufactured so cannot be purchased you will have to make it if you want one. It is fitted to the cross or top slide of a lathe and the file runs on the two rollers which have a stop step enabling the file to be located in the same position every time. It is height adjustable so you can file a flat on any round item held in the lathes chuck. And if the chuck is indexed you can file any number of flats on a round bar without removing it from the chuck and also bypassing the need to set it up in another machine to shape it when making a one off and with a shim placed under one side you can produce a flat that tapers.
It is archaic and half a century old now but worth its weight in gold if you want to produce a tapering four sided punch quickly.
Sometimes I feel the world is slowly haemorrhaging small clever devices like this as each generation slips off their mortal coil. I can see my sons looking at it and wondering what it is when I have left this world, and not knowing throw it away!!!!

The tapered square punch is such simple solution once you know, been picking up the gun and looking at it all day and I'm pleased as punch ( excuse the pun ) I really think there is a need for a "how to" or DIY section. There are many of us that enjoy restoring old pieces of equipment and there should be a thread so people can share knowledge and expertise more easily to help us all expand our skill range. Like with barrel browning and blueing it allows us to perfect a technique and pass skills on.

Damascus that is exactly the point. Over the last 30 years we have blinded our vision thinking that we need the latest and greatest in technology to make anything worthwhile. While technology has it's advantages only a fool would deny, simple tech like the image above is as much a part of our gun making and smithing heritage as the guns we love to shoot; it emphasizes the point that these skills and knowledge must be passed on.

damascus,
A device like this is called a "filing rest" here in the US.As it happens, if anyone is interested in making one, there is an excellent "how to" article in the May/June issue of The Home Shop Machinist magazine. This is a Village Press puplication and in addition to subscriptions is avaliable on some larger news stands.The filing rest described in the article fits in a quick change tool holder, which itself is adjustable for height, and another part of the article describes making a toolholder also.

A "DIY" subforum. What a good idea!

There's a single shot mortice tutorial floating around here that shows a simple hardened scraper with a 90* corner that can do a really nice job in an unplugged milling machine to create clean corners in a square hole.

+1 to the idea of a restoration section for amateur and professional 'smiths, specific to doubles - fitting hammers, browning barrels, raising dents, refinishing and re chequering stocks etc; I bet there's enough projects which'd be overcapitalised by paying a 'smith sitting in people's batterys and enough people who'd like to have a go.

Another benefit of a DIY subforum is that it would enable people to see the extent of the work involved when contemplating a project. People then would be able to make a better decision whether to try to tackle it themselves or choose to have it done by a professional.
