I love that wall . . . some beautiful stonework there (I have some very old 'whinstone rubble' walls that need work :roll: ).
But, what is in the 'stew' . . Evaporust ??

Thanks for the compliment, but the wall is nothing fancy - cast concrete blocks made to look like stone. Yours is much more interesting. It does make a very stable workbench out in the weather.

The stew is 3lbs of lye in about 25-30 gallons of water. The tank is the bottom of a 50 gallon electric water heater so it warms up to 130F or so.

It strips paint and grease well but aluminum quickly rots away. Brass and bronze survive much better, but I suspect they would also eventually corrode away. Iron and steel only!

The brazings and brass seem fine sitting over night or even for a couple days. I can't see a change except the grease is gone. It probably corrodes due to electrolysis like zinc anodes on a steel ship.

Machined a late axle to fit the early frame. Had to make some spacers too. This is the first real work done with my new (to me) 1955 lathe. :D

10" South Bend ("heavy 10") from about 1955. It too has become a hobby. I've rebuilt the lighter colored sections.

very nice! I used to have a small 9"Model A but I swopped it for a Weiler LD220 as I could not get my head around the Imperials :)
