Limited workshop space, unlimited interests... "The Littlest Workshop" the bastard child of "The Little House On The Prairie" and "The Littlest Hobo" TV shows. My interests include EDM, CNC, Camping, injection moulding, welding, inventing, casting, bushcraft, composites, 3D printing, micro-RC, ornithopters, optics, microcontrollers, Ukulele, lock picking, cycling, safe cracking, motorcycle restoration ... Maybe tomorrow my projects will be finished?

Getting blood from a stone
Well not quite but getting the binder from its bottle at the bottom of the machine all the way to the print head is proving a challenge. I've flushed most of the lines and found a blockage at the input to a filter and now it gets all the way to its little header tank but it shows no sign of going any further. The primer pump is not working, this is a solenoid operated metering pump by Valcor scientific (an SV560) I stripped it down and I think the o-rings are past it. Nothing in my kits will fit nor can be made to fit but looking on the yahoo group reveals a kit from the pump manufacturer is only 33usd, that's OK but it might take a while to come :( boo hoo but a chance to have a clean I guess.
