Re: Butterfly firebox doors

I have a 3D model of the 1.5" butterfly doors that I cast for my Mike.

I may be possible to scale them up a bit (they are already scaled up for functionality - a fist needs to fit).

Re: Tapping Pipe Fittings

I made some split - round holders, held together with two SHCS.

I'll take some pictures of them and post them.

Re: Steam turbo generator

Howard,

You are correct, my mistake (I can always claim the little label is hard to read ;)

There are two original Mosley turbogenerators within our group and my casting match.

I bought them as a dummy turbogenerator set from the vendor that owned them before L.E. (I don't remember the name).

Re: Steam turbo generator

I believe that the MO5 (the set with the Quarter) is the same patterns as used in the Mosley design.
There is a bearing recess in the front casting.
I have a design for making it functional and if I ever get my butt in gear, I'll have it published in LS&OR.

Re: Tender Tank

18 out of 1000 I got some 316 stainless, 0.070 thick for a great price at a junkyard. I had it waterjet cut, both the outline and rivet pilot holes. To my surprise, the rivets (properly set) are water tight. The only sealing with solder I had to do was the bottom row - the rivet tool could not be pe...

Re: Steam turbine generator

RN - I agree, the exhaust just exits. I pulled apart a old Mosley generator. The turbine configuration was puzzling to me. I'm not a turbine expert, but I believe the steam should flow, and expand, through the airfoil of the blade, not just 'blow' it around. 2012-05-05 17.03.45.jpg Here is my curren...

Re: Steam turbine generator

John, I am nearly done with the alternator portion of the generator. Instead of the rotor made of pieces and alnico magnets, I bought a 1/2 dia x 1/2 long, diametrically magnetized, rare earth magnet (K&J magnetics) I bought castings from a supplier (I can't recall the name, now owned by Little Engi...
