I purchased a display cabinet this week that looks like it is going to work ok. the cabinet is 3' long 3' tall and 2 foot deep all glass with a wood frame. I will install the compressor under the mill out of site.
I took a pop up camper in for free, I was going to scrap it. the roof ac leaked and every piece of wood in it fell apart. I removed all the wood with a broom and shovel. the cabinet frames were metal and still ok and the linoleum protected the floor so I gutted it out and replaced all the wood. I bought a sewing machine and repaired the canvas and it is coming out ok. another skill I had to learn... I need to catch up on my photo taking of the mill project and the camper and post them.
I built the silent compressor for the mill with the pressure controller and safety valve and it is so quiet you cant hear it run. It will cycle with the mill running continuously but I'm installing a momentary switch to run the mill only when you hold the button.
as far as the next project I'm thinking about building a small cnc surface/contour grinder, I already have the motors, electronics, ball screws and a large X/Y table.
Thanks for offering ideas
the steam tractors and locomotives are interesting, I have grandsons that will be old enough for go carts soon also. my oldest sons last go cart was 650cc 110hp Jet-ski engine. water cooled, it's still in the shed also. It was too scary to drive, you had to let off or the cart would not turn a sharp corner. I built it all out of aluminum and it didn't weight enough to keep the front end down even with the driver and engine, everything in front of the rear wheels a mid engine configuration.
