Chris, this is the first time I have seen the hold down clamps used with a block of wood, now the choice becomes what wood to choose? Hmmmm would save me from removing the big vice and then having to square it all up again.Mike
Good morning Chris,Boy that penny in the photo really brings to scale the small size of that engine. Beautiful job Have a great day,Thomas
That stand must have been a very heavy piece of cast iron on the original shovel. Sturdy though. Nice job on the fab!
Yeah, it may be a simple part to fab, but think about the poor schmoe that had to cast that back in the day. That's a deep casting no matter which way you orient it. Even if you made into a 2 part pattern that separated at the shelf level, it's still a long ways into the sand.The skill of the old foundrymen amazes me looking at some of the parts they cast, and it all had to be done manually. Carving the patterns, prepping the molds, pouring the iron, all of it had to be done by hand, or at most with some manually controlled equipment. I was looking at a cast iron part of a roll set today that was probably 60-80 years old. It was nothing but curves and it was not a solid cast iron part, it was cast with a core. Those guys deserve a lot of respect for what they were able to do.Think about how complex the steam controls for the original Marion were, that took a lot of skill to be able to cast that and get a usable part. You can bet that the boss let them know when the number of rejects got too high.Don
Hi Chris, Tried to copy past picture but that didn’t work.Ok a block that fits between the block behind the tracks, & the block that has the handle on it, the height so that it fits between the base & the under side of the frames....... does that make more sense?Oh on the devils advocate front, the only thing holding the straps are the screws........ The little engine is looking neat!Cheers Kerrin
I follow your description, will do some experimenting. Maybe a block that locks over the the tracks and frame.

I'd hate to read that your air-bags saved your life in the crash, only for you to be taken out by your own model hitting you in the head.You've already said that you're going to strap the board handles down to the tie-down points and that the handles are through-bolted, so the weak link is the Velcro straps.Don
The model is in the back of the car, it would not fit between/over the seat back anyway, so I think you are over-inflating (air bag, inflate...) the issue a bit.

Sorry, didn't know there was another seat between you and it that would slow the model down.We gotta watch out for the big Elf you know, where else are we gonna get our fix of machining porn?Don
