I'm not sure there is a commercial conversion kit. you an get appropriate sized hiwin balls screws but like the block that holds the two ball nuts had to be completely fabricated, the z quill axis was pretty much the same. the electrics are the 220 volt ac servos and and drivers and breakout...
stuff is shielded and all as per the factory recommendations. and I did not bundle the encoder wires , power wires and , prox. wires , would look alot nicer though.
I was thinking mine is over built with 1kw servos and the matching drivers , and I'm running it maybe once or twice a week. Ive got spike arrestors on every thing that you can. and a couple 5" cooling fans with filters blowing thru the box. so I'm guessing heat isn't the problem.
I've had several failures over the last 7 years of various electronic parts in my DIY cnc conversion of my bridgeport styled enco knee mill. I've gone thru 3 servo drives and 3 breakout boards and 4 proximity switches all just sorta out of the blue where its running fine and then its not...
In a sortof related problem is the check vlv on steam engine oilers seem to be really prone to getting debris in them. I'd like to see some really decent check vlv designs for different fluids and pressures.
Usually happens when the load on my 1/3 scale traction engine is removed also but there it allows the fire to reduce dropping steam generation a tad, better than popping the relief valve.
one thing that needs addressing is the cyl oil in the condensate from a reciprocating engine , turbines don't have that problem. but there are schemes for getting it done. I saw a full size A.D. Baker traction engine where it was using both super heaters and recaptured water at like 300 psi...
Do I have this correct ,your planning on building a boiler out of 3/16 wall aluminum tube 4 inches in dia. . the end caps are held on with 8-32 screws and sealed with rubber o rings . your planning on running this at 50-100psi?
On many of full size traction engine boilers and some models , in the us don't use a bushing for any penetration's where they can get like 3 threads. Some of the crown sheets don't have a bushing where the fusible plug penetrates. Alot of the models and or new boilers do have bushings...
