Re: Water quick-disconnects for tender/loco

If I remember correctly, I used automotive fuel injection line tubing. It is flexible, inert to chemicals it might encounter, internally reinforced, and can take the pressure of hydrostatic pressure test of the boiler, using the tender hand pump. And it is available in various diameters. You can see...

Re: Water quick-disconnects for tender/loco

I use Hanson quick-connect fittings on both my locomotives. 'Have worked perfectly for 15 years.
My accessory connections use the same: External air for fire-up, Blowdown outlets for water fill, and more.

Re: mallet locomotive

Can you share more info about the locomotive's scale, gauge, or where built?

Those facts could help identify it to answer your question.

Re: no power g0619 grizzly (seig sx3)

I would use a Volt meter to try to find where the power is being interrupted.
Start at physically active items first like mechanical switches.

Equally amazing is the restoration on Baldwin's smallest Mallet, SKOOKUM. 2-4-4-2. I rode it during steam tests in May this year, in Garibaldi, Oregon, USA. Two of the most unlikely ...

Re: Turning plastic on a metal lathe

One plastic to be careful when machining:
PVC.
It can off-gas chlorine which will quickly rust any exposed metal surfaces.
I always prep the machines by applying a coating of oil for protection.
It wipes clean when the job in done.
