Re: Wanted Brake shoes

I make separate castings for a 33" scale brake shoe, brake shoe head, brake shoe key and a brake beam spreader. The brake beam is made from a piece of 1/4" square stock and some 5/#2 wire and the spreader. The brake shoe head go on the ends of the 1/4" square stock. The 5/32" rod stiffens the bar, l...

Re: Feedback requested, PRR junction box

Print your parts about 5% oversize, use the part as a master pattern, make a rubber mold from your master, shoot your waxes and cast from that. You could also, if your drawing software allows you to convert your drawing into a reverse file and print a mold in anything that will take the temperature ...

Re: 3/4" Scale J1e

Fittings are fittings.
Fitting may be large in one scale and small in another scale.

Re: 3/4" Scale J1e

As time and energy allows David and I will be bringing back the valves and union ells that Barry made. Barry owns the tooling. I already have made the unions, they are octagonal. The pipe fittings generally used on locomotives are 300 lb. AAR malleable iron fittings. Forged steel fittings were gener...

Re: Consequences due to lack of penetration because of inexperience welders.

Actually poorly brazed small through hull fittings. Possibly damaged by earlier shock testing. The failure caused a reactor scram. An attempt to restart the reactor failed. There was negative buoyancy on the boat. When an attempt to do an emergency blow of the ballast tanks resulted in moisture in t...

Re: Consequences due to lack of penetration because of inexperience welders.

Mr Ron, Which ship yard did you work at when that bad welding was found?
That welder should have been publicly shot for that stunt.
I lost two good friends when the SSN Thresher was lost.
If not for that I would have entered the nuclear navy.

Re: Consequences due to lack of penetration because of inexperience welders.

One problem eventually discovered was "null ductility". At low temperature steel loses its ability to flex and assumes some of the properties of glass. This was discovered when a ship in Boston harbor snapped in half on a very cold winter night. Structural failures of liberty ships occurred in cold ...

Re: New Old Baldor Buffer

Grit gets into everything. Double shielded bearings are used to reduce friction. My super expensive Swiss drill sharpener used them. They failed in about eighteen months. The experts pronounced the drill sharpener unrepairable. New sealed bearings solved the problem. No problems and the drill sharpe...

Re: New Old Baldor Buffer

You should use sealed, not shielded bearings.
Dust and grit will get into shielded bearings.
