    I'll take Picture 2, C D and I

    PM incoming!

    You can get close to what you need off the shelf from Sopko:
    William Sopko & Sons Co., Inc - Standard Taper Wheel Adapters
    Take a look in the second section down. They offer adapters with long...
  3. It's the other side of the state from you but...

    It's the other side of the state from you but Tru-Tone in Brooklyn has done a few thousand parts for me over the past 10 years. From the size of a thumbnail up to 36" long, I've never had them lose...

    I second this. The brand I use is called Chip Quik and it works great for SMD and thru-hole in my experience. Load it on with flux to both rows of pins and it's very easy to keep everything molten at...

    I had the exact same issue with my HLV compound base. My HLV came with the end of the compound lock cam broken off and all kinds of crud between the compound base and the cross slide. I put it up on...

    Agreed with the above, what do you need the partner for at this point? Great that you're starting in your own building and can hopefully get work with just a plasma table, that's nice and low risk. A...

    Many lamp parts still use 27 TPI threads, mainly 1/8 NPS threaded tubes/nuts and 1/4-27 nuts for on top of a shade harp. These guys may carry some of what you need, though it may be buried under one...

    I will second Matt's experience. I've had a 6061 subplate on a 30x16 VMC for 12 years now and when I pull it off (every 3 years or so) the table looks like Matt's. A few minutes with scotch-brite and...

    I don't agree that Galil HW is crap but it's important to realize that their controllers are made for generic motion control applications and not specifically for machine tools. To properly implement...

    I agree that the dock-only situation can be completely fine. Having a shop in the city means a lot of buildings are dock height only. I've had my shop in 3 of them so far! My last space was ground...

    Put me on the list for a spring class in VT if one happens.

    Here's my partial set that I picked up years ago. I bought it cheap for the cylinder square and out of curiosity. Please shed a tear with me for the rust damage on the master flat, it was that way...
  13. B&S #13 Tool and Cutter grinder (old style), FREE Brooklyn NY

    It's been a few years since I've posted (I was spending way too much time reading PM so I had to cut myself off for a while) but I thought I would put this machine up to see if anyone was interested...

    Larry means the collet's max OD, not max capacity.

    Back to the OP, ER8 is close and has the 3/16" capacity.

    Thanks everyone for the advice. It's very helpful to get everyone's ideas.

    A push/pull cable arrangement would be great but I need 12" of movement @ 150lbs or so which seems a bit past the...

    Crap, i meant to put this thread in general!

    I would normally not use hydraulics as my expertise is in electromechanical systems but for a variety of reasons I wasn't able to come up with a...
  17. Would a configuration like this work if I needed...

    Would a configuration like this work if I needed all the cylinders to move completely in sync with each other? It's obviously easy to have them match up at the travel extremes but I need them to be...
  18. Yeah, I am uncomfortable with not having any...

    Yeah, I am uncomfortable with not having any recourse if something leaks. This is very low load, low duty cycle and it can be rebuilt every time it is displayed (likely to be for a few months max) if...
  19. Hydraulic system design advice, closed system of 2 single acting cylinders

    I'm doing some design work for a kinetic sculpture and I'm considering using a simple, low pressure hydraulic system for actuation. Ideally I'd like to use a pair of single acting cylinders attached...

    I stopped by last night and highly recommend attending if you ever have the chance. Aside from the engine room which has been thoroughly described elsewhere...

    I thought for sure this would be a simple fix but yeah, I am on to plan B. No parts diagram + no time + Christmas = throw in the towel. I've got enough oil on my clothes for one day.

    Actually, I take that back. It sounds like it's pumping a fair amount of air as well as leaking internally. With the fill plug open I can hear air bubbles when pumping with the handle pulled in....

    I'm pretty certain it's not an air issue.

    I've had it apart a bit more and now things are even worse. I'm thinking that I must have lost a part.

    Here is the main check valve assembly

    I just accidentally overfilled it, definitely enough oil in there.

    Now that I think about it more it seems like the tapered plug might function as both check valves in the same part (two tapered...

    The springs are definitely where they were, I did manage to keep track of that.
    I realize there is another check valve in the system between the main cylinder and the pump cylinder but I'm not sure...
