Things to do

Always things to do. Finally got to where I decided to finish my boiler so I'm cutting out parts from steel. Between cutting torch, milling machine, and lathe. Found a nice carbide end mill just right for boring the tube holes, (in the box of milling bits that came with the machine) But no 1.25" nmtb40 adapter for it. (got everything up to 1"
so ordered one off ebay. Also found a carbide taper bit that cuts out the weld V's quite nicely. Got a used oil torch set up for preheating weld joints. (picked up several hundred gallons old oil to play with) Finishing the ofeldt first. (designed for 600 psi operating but I'm going to run it at not over 200 since all my engines won't be high pressure capable, unless I convert an IC engine, then I might be able to use it higher) First engine is the westinghouse 1885 design. Second boiler will be small fire tube vertical, got a half inch thick shell for it and plenty of scd 40 pipe, instead of no water leg or a normal stay bolted water leg, think I'll make a water pipe extension on the bottom to surround the firebox since there's a taper to the pipe shell from 16" at bottom to 12" top. (found a water tube boiler design with closed bottom tubes, using small tubes down the middle of them to carry water down. But I'd connect the bottoms with at least small tubing so they would all drain at shutdown.) It'll be set for running at 150 psi but according to the pipe ratings 1000 psi would not strain it. I like a large safety factor and double pressure relief, a regular relief valve and a soft plug that will blow at a bit higher than the relief. 3rd boiler will likely be a yarrow style. Probably run at 200 psi. 2nd and 3rd engines will be entirely from scratch from a pile of scrap metal, by way of the foundry and shop machines. I plan on 3 trucks, from a small one (jeep frame maybe) mid size truck is already here, my retired to offroad 3/4 ton dodge. big one eventually would be an old military 5 ton, cab and engine removed, as well as second rear axle. need a good strong winch on front, maybe a dedicated engine for it, (steam donkey engine) maybe a set of flotation tractor tires like used on spreader trucks filled with liquid weight. That will be the ultimate offroad steam machine, mostly for woods and agriculture support work but an occasional camping trip into some remote canyon is quite feasible. Mystify the occasional fellow offroader with what sounds like an ancient loco steaming through the canyon. That's the things to do plan anyway. From short term to long term. First version may not be far off, but the second and then third will be awhile in coming likely, since I have plenty of other stuff to do as well. Like designing and building generators and motors of nonstandard types and getting ag production going better. Gotta make a livin, but the steam machines can help out with it.

The show was fantastic, I got to see many old friends both from the model club and the steam boaters as well as many steam car guys. Great time.
There were three cars at the show a nice 1901 locomobile an Oldsmobile and one other I did not know.
Saturday was extremely crowded, I brought two models I had completed this past fall and winter.
My scale model of the Herreshoff forced circulation generator and my 1/8 scale 30 HP 1905 narrow frame Stanley engine.
