Re: Disasters, Out-takes, Accidents, Fails etc.
Failure? Hmmm, that would be myself. I have a knack of failing at most things I do.
A slitting saw is just a saw blade. You need a mandrel to mount it on so it can be chucked in the mill or lathe.
Mild steel is dirt cheap when you buy it in bulk. We pay less than a Pound per kg. However in small quantities the cost quickly adds up. I'm fortunate that I can scrounge all the off-cuts I want.
Best to use a schottky diode as they have less voltage drop. Any normal diode will work though provided the solar cell voltage is high enough.
As Philipy said, don't worry about using a 5V solar panel with a 1.2V cell. Unless very big, the solar cell will not provide enough current to do any harm.
1702 NPN transistor. Google it for spec sheets.
What I meant was, I doubt there is a market for track from either material. Unless you are in Denmark and willing to weld the track yourself it would become too expensive compared to commercially available track. It works our cheap for me though as a DIY project.
I think with stainless steel you would have a market for this, great work.
I doubt that. Shipping will be a killer and by the time it's been welded the price would be close to Peco track.
Are you able to use stainless steel?
Yes, I can cut that as well. I have a TIG welder for joining the track.
