I am looking at buying a LMS 5100. I have watched many videos done by Frank Hoose as well as being on his website and others and yet have seen anyone do what I need to do with the machine.
I need to make a "Pistonrod" like the one in picture below to the right. Poorly drawn for this thread. It should be made easy enough it is less then 10" long and 2" in diameter with the rod being .25 of an inch . What I am not showing is that the lower portion is meant to be fit into a cylinder dish and needs to form a oval shape.
Here is the piston dish shape I want to weld my piece to and need to confirm the shape to match.

I can not spin a oval though.
Now that could be outsourced then have it welded to the piece I make on the lathe easily enough.
But the next part is something I do not want to outsource.
Here is my "head"(poorly drawn for this thread with the valves that should be 1/8 more towards the outsides). The thing is in 3 parts and the valve passageways will experience up to 5500 psig constant pressure and up to 700F. It is going to be milled from 4x4x1" material of steel. I am planning on making brass valves that are .5" in diameter. The center section "slides out" so the piston can be removed for disassembly and heads serviced. The top and bottom sections separate which will allow me to cut the valve recesses and flow passage ways.
Here is the problem.
I want place what will be 4x4x1/2 thick material vertically in a vice mounted to the compound and move that into position so that a bit in the chuck to cut the valve recesses and face. Then I want to change out bits so I can pull the piece and cut a passage way for the high pressure to flow to the valve passage way around the valve face to be eventually injected around the valve into the cylinder.
Now the thing advertises enough slide to make this possible. But I am unsure if I will have to much side load in doing this. The lower portion of the piston valve would also need to be milled in the same manner placing the material in a vise and having a tool in the vise removing material that way.
Ideally I would like to make the piston/rod/base that will be welded to the gas piston from one piece of 3.8"x12 diameter aluminum rod.
Is this something that can be done from the LMS 5100?
This will be my first lathe. I am going to be experimenting with these heads finding flaws and fixing them. As you can imagine I do not want to outsource the thing each and every time I want to make a design change. If the 5100 can make the cuts I want without it being a issue the deal is done. If it is going to be a issue I will be looking at different machines.
Thank you for your time and and advise.
