Relieving liners?

[Travis Fry]

Ok, I just posted about whether to get a grinder or a mill, and I've decided on the grinder. I still need to relieve liners for my slippies. I've used bronze washers and didn't hate it, but I'd rather not deal with them. So, without a mill, how do I relieve liners in stainless AND brass?

I haven't made but a couple of traditional slip joints, but I have a couple of ideas and tried a couple different things. One was the Lake method of hand scraping, the other I made a tool for it.

The hand scraping takes a bit of time and some skill. The tool I made was basically a small block of wood with a brass pin through it and a washer glued in the center. I glued sand paper to the washer and put one end of the pin through the liner pin hole, the other in the drill press and basically sanded the relief in.

Hope this helps.

I place a pin in the liner and mount the blade and with a sharpie I mark where the relief needs to be. Currently I use a mill but before I became rich and famous, i used a dremmel tool, I started with a grinding stone and finished with a craydex with some rouge, worked really well. Be sure to put the liners together and make sure where the edges of the relief match on the top and bottom.

I have also seen a slip joint WIP where the maker used his electro etcher to etch away material to create the necessary relief. I thought it was pretty clever, but I have access to a mill and a small rotary table, so I'm sticking with that method.
