Re: 1908 Stanley hand brake
Hear are a few drawing of how I built the emergency brake locking hardware.
My 1906 did not have this hardware, but I added outside brakes drums and copied the hardware from a 1907 car.
I also added a brake light and brake switch.

Spring City Steam Works Reports:

​22nd July 2019

While it's crazy hot and in between the new kid prep.... I'm printing some fixtures to test out and help decide on the fixtures for the pancake coils for the Mason. Hopefully a little bending and fixture time this week!

23rd July 2019

One may have been thinking... Why the need to pallet jack the weld table around.... Well, I'm trying to take a 21 foot piece of pipe and wind it into a double stacked pancake flat coil of pipe to replace some coils in the Mason's monotube steam generator. Shops too small, so out in the driveway it goes!!
As for the 3d printed pieces, I'm working out how to fixture the hairpin bent pipe so that the top leg is ~1/4" gap above the lower when it gets wound into a coil. The center section will be made of steel and there will be a clamp on top as well as the pipe getting tack welded to the clamp. Then the 11 foot long top pipe will swing a huge circle as the lower pipe is wound on itself to make the pancake coil. The whole mess then gets flipped over and hopefully that leg winds into a nice pancake below it. Works in my head, got to refine the pieces a little and make some chips and then try that plan out!!! ​
