Today, it was snowing a lot, then raining, then sleet and back to snow. It was so bad I lost my wireless internet service and my satellite TV. Plus tromping thru the fields wasn't going to happen.
So I sat down and sketched out a simple to build lube extractor for 4 to 6 inch 1 inch PVC tubes. I have not noted the support system or platform on this drawing because I haven't built it yet, but it most likely will be mounted on a piece of 4 x4 lumber. I do have better materials out in the machine shop, but I thought I would design simple so anyone could build it, sort of a VolksLubeExtrator. :)
You need a 9 to 10 inch C Clamp, and 4 or 5 EMT 1 inch clamps to build this with. In the drawing I cut the bottom part of the C Clamp off and mounted the EMT clamps in alignment with the ram face of the acme screw shaft of the clamp. Put the tube mold in the clamps after the lube has cooled. Then tighten the EMT clamps around the mold. Turn the screw shaft slowly, and it will push the lube out. You may need to put a 1 icnh washer between the ram and the lube to span the diameter of the mold
I have tried this in a little different form to see if it will work and it does, so I thought I would build one that anyone can make.
Construction notes, I cut the bottom of the C Clamp off with an abrasive saw, but a hacksaw will also work. For the mounting this on wood, I am going to route a slot on the 4 x 4 for the spine of C Clamp to go into, this can also be done with a DADO saw. I will probably drill holes to hold the C Clamp in place, right thru the wood and the clamp, then use bolts or rod to hold the C Clamp in place with the wood. Mounting the EMT clamps is simple, use a 1 to 1 1/2 inch lag bolt with a washer and line them up with the ram face of the clamp.
Hope this helps some one out there. When I build mine, I will put up pictures.
