yes I actually put it together and tried it , have some seal reworking to do . It leaked between pump and motor . Yes ,I'll be the guinea pig on this 1 ,and will not give up till it works . need less to say nothing will be running anytime soon , lot of small parts to make . I need to get some chunks of aluminum to make 4 trannies for the scrapers , 2 reversers for this , valves , and pumps . if the vain is a no go then back to the gears .

well I got my pump working still got to get a shaft seal , A quad ring just not going to cut it ( should've known better ) . now on to the next unaffordable part valves . I think I'm going to wear this taig mill out with these 3 machines

Nice work on the pump - a vane pump you say. Wow, nice work. Would a press fit bronze SAE863 collar on the shaft help seal it? Are you planning to make the valves? If so, are you going to do a closed or open hydraulic system?

Nice progress Steve. Pump looks good!

Those HD brand servos I told you about on the phone don't like to sit for a long time under load, they have so much holding strength that they burn up from heat. So, they probably would be good to move/hold valves.

I'm might try something off the shelf first . not sure yet on open or closed . as for seal , I just used what I had laying around to try it out .

thanks Scott , any servo holding a load for a long period of time is not good for it , I would think . I'll cross that 1 when I can get to it .
