Thanks Cat , 1st it started as a pic from the sales brochure imported into auto-cad , scaled to 1:14 scale , many hrs. of tracing and tuning up the tracing . 2nd ,many hrs. of design of all the components as an assembly .
3rd , break the assembly into parts , duplicate where needed , place parts of same thickness on that certain thickness plate in such a way as to min. waste . keep in mind I'm doing all my designs in 2D . 4th import part plate file to cam , hrs. of programing ( for me any way ) , simulate to make sure everything is what you want (IMPORTANT) double check , triple check , maybe quad check . 5th, load file in machine and set up (IMPORTANT) double check , triple check , maybe quad check 6th , push green button and watch crunching action in blink of eye only if you DID NOT , double check , triple check , maybe quad check . As you can see this CNC thing has and still is a rough road for me yet I still like hand cranks , but , with what I can do on the VMC now , this CNC thing is catching on .

A few pics of to days carnage I made a bunch of brass shavings and a few parts (cylinders ) not quite done ran outa day + the groving bar I made with major inferior material didn't werk so I gotta order 1 Need to cut the ID seal grooves in the glands . I also got the front drive shaft hooked up last evening . I also remade the engine hood . the 1st was made from scrap panel from a delivery van which didn't bend to well without breaking ( not 6061 ) so I picked up a peice of .125" 6061 sheet and re ran it . No pics of the new 1 , forgot that pic .







thanks fer looking

hood in the back ground of this pic

just a few pics of what I've been pecking away at here and there . I know my copper lines are ugly but lets see howw all werks then I might make them purtier







remade the deck plate since the 1st looked like dog poo after tryin to weld the rim around . So I milled it out of .75 " plate

old


new


oil vent/fill


for size comparison . I have it sitting on a 24" x 12" x 1.625" plate in the mill



thanks fer lookin back too the grindstone

IH,
can you show some detailed photos of the end seals for the rams you have made and give an indication of the physical size along with whether you had any issues with leaks etc. Love the build, looks awesome.

Cheers
