The Home Machinist!

I love my Chicago Pneumatic squeezer!
Used for Bill Harris Steam Roller project...

I also have Loco-Notes 1, 1a, 2, 2a, 3, 3a and 3b. Picked these up at a LALS President's Auction. Gary had passed by the time I joined the club in the mid 70's. Cary Stewart may weigh in, he knows this history...

On Coventry's D30, the boiler to smokebox joint and the smokebox to smokebox face joints are 16 each slotted round head 3-4...

Working on my Coventry B&O D30 0-6-0. In practice, does anybody on run day go in the actual smokebox door or just remove the entire smokebox front? I can't see any real work being done through the smaller door, and not sure I want to mess with 12 door dogs. 32 bolts on the front, are 8 real ones...

I have a pile of 2.5" stuff, wood and production patterns too. Have no idea whose they are. Probably need to get rid of it sometime... John
