Re: Keyways

Woofruff keys suck in my opinion. They do not assemble and dissassembly well. The key tends to rock and bind, which can make really tough to get apart. You also need a special cutter to make the slots as well. Straight keys work well, you can mill the slots with either a 2 flute end mill (low cost) ...

Re: Regauging a 7 1/4" Minnie Project

Set the eccentrics and timed the valves today. Also blocked it up and ran it on air. A little stiffer than I would like it to be, but it sounded square in forward and reverse,

Sorry do not know how to make Utube videos.

Pinning the eccentrics next, I don't trust set screws not to slip.

Re: Two Silver Soldering Questions

Get a few fire bricks to solder on making a three sided hearth. Holds the heat in nicely when working on small stuff. I have found that MAPP gas seems to work better than propane, for me anyway. I also use the black flux for everything.

Re: Union copper tube to 1/4-40 MTP ?

Not just an internal ACME thread it is also left hand. First thing I ground a cutter for and machined after I purchased my 1927 9" South Bend. Made an aluminum practice one and then a brass one. Few months later a shop teacher friend gave me some when the school cleared out its metal shop. Very time...

Re: How do I make this?

Two methods. One is to solder a tube or rod to flat stock and machine or file out the areas to make the parts to mate up as a hinge. Use silver solder for stronger part. The other is to machine from solid stock using end mill and then machine the rounded area with a radius end mill. This is assuming...

Re: Union copper tube to 1/4-40 MTP ?

I also make my own unions. But I use commercial compression brass tube nuts. I use one size smaller than the tube size it's made for. Bore the nut to accept a lathe made feral and make a mating feral from hex stock with a threaded end screw the nut onto. The hex feral can have either external thread...

Re: Allen steam fittings

This is what I did for the exhaust attachment on my ten wheeler. I machined the cone off the face of a NPT to flare adaptor to make it a but fitting, I also machined the hex on the flare nut to be slightly smaller for wrench clearance. This set up slows you to center the blast nozzle as well.
