Re: LocoParts?
A little off-topic, but I fail to understand why any website that exists to sell a product would use one of the "weird" top-level domains (TLD), such as .biz . I can't speak for others, but I would never even think to search for a <insert_your_domain>.biz address, or .info, .tv or some of the other ...

Have you given any thought to cooling your motors?

Re: Does 404 SS anneal and become malleable?
Why not Argon? Argon is suitable but the weld quality may not be as cosmetically pleasing. In my experience, tri-mix seems to be more forgiving with stainless alloys. It depends a lot on the weldor's skill. Can't say that i have ever heard of or seen a reference to using tri mix for TIG welding sta...

Re: Materials Question
I've been using some hammer faces (that are described hard white nylon) on some specialty hammers...I've made a pair out of Delrin for one of the folks to test. I'm only using Delrin as a test, since I have some on hand. I'm not sure if Delrin is a better or worse substitute material for the nylon....

Re: Does 404 SS anneal and become malleable?
followed by rapid air cooling. Can you expand on that? Steel is normally annealed by slow cooling. 404 is an exception. If you are still in doubt look it up. :D All the welding capability I have is silver brazing and flux core which it usually turns out looking like solidified volcanic lava all rou...

Re: Does 404 SS anneal and become malleable?
As stainless alloys go, it's easy to weld via the tungsten-inert-gas (TIG) process, using tri-mix as the shielding gas and a compatible filler. Why not Argon? Argon is suitable but the weld quality may not be as cosmetically pleasing. In my experience, tri-mix seems to be more forgiving with stainl...

Re: Electric power prime
Turns out, one motor would be sufficient for torque and tractive effort. However, I want to go with two motors, one on each truck, to better distribute tractive effort to all four axles. Also, such an arrangement reduces the temperature rise in each motor. Overheated and burned-out traction motors ...

Re: Lathe LUBE advice needed
Mobil's Vactra machine oil is a good choice that is readily available. That's what I used with my lathe.

Re: Does 404 SS anneal and become malleable?
Type 404's chemical composition includes a trace amount of carbon and a small amount of nickel, but much less nickel than typically found in 300-series alloys, which sort of makes 404 an austenitic/ferritic hybrid. 404 will not respond to heat treatment, but can be annealed by raising it above its t...
