Re: Is this a logging maintenance loco? I want to build one

As Bill mentioned , you may want to look up the Tom Thumb Loco for drawings and photos
It does not have the beam, but looks almost as neat.
I think there was a Live steam model ( 1/2" scale ?) that was published in the 1930's in Model Craftsman Magazine
Someone here may have a reference

Re: Band saw mod

Yes, as others have said, a metal blade works for Aluminum --but thats it ----unless you slow the blade down.

Re: Way oil

Probably the biggest advantage of way oil, over every other oil is its ability To PREVENT stick slip. They are specially formulated to allow carriages/tables to move with minimal effort. You see it when you are trying to sneak up to a dimension and the last few thousandths are tougher. Put a dial in...

They have Die inserts ( threaded cut edges) that can be resharpened and in order to allow that, the heads are adjustable...
