Experience needed here.

On Pony pipe clamps what is the little 7 or 8 turn spring for? Clamps are 1/2” pipe clamps. The moving end has a spring in it along with the 3 or 4 metal “grabbers” that hold the pipe. The fixed end that goes where the turning gizmo is does not seem to have room for this spring.

I have a 20 year old Brookstone tri stone device with two Arky stones soft and hard and one Aluminum Oxide or whatever stone. The Aluminunm stone is starting to get a belly in it. What is best to use for flattening it?
I mostly use it now for flattening plane and chisel backs. It is aggressive and I like that for taking the first few strokes. Also the honing oil and filing and grit has kind of started a glazing over, should I soak this in gasoline or kerosene to get rid of the oil clogging? I’ve always used honing oil but I have a couple of cans of Marvel’s Mystry Oil, can I use this for a honing oil?

Thanks in advance for any replies

If you get a piece of plate glass (mdf will work as well) and attach a piece of 120 grit sandpaper to it you can run your stone back and forth over that and get it flat. Once it is close to flat work up to 220 grit sandpaper. You can also do the same thing to clean up the glazing on the other stone faces. Honing oil is the only thing I have used for my stones – not sure what Marvel will do.

The spring keeps the rings positioned so they grab into the pipe when you apply pressure to the slider piece. If it wasn’t there, you would have to hold the rings in position while turning the clamp handle- hard to do with a wide piece.

The PONY Pipe Clamp Fixture is one of the handiest tools in any shop. One set of PONY Pipe Clamp Fixtures can be used to make any number of different length bar clamps simply by using the fixture on different lengths of pipe. Heavy-Duty black pipe is recommended. No tools are required for assembly. Simply screw the head assembly onto the pipe threads at one end. Slide the tail-stop onto the pipe at the other end. Then apply the coil-spring stop to the pipe threads at the tail-stop end of the pipe to prevent the tail-stop from sliding off the pipe during adjustment away from the work being clamped. PONY Pipe Clamp Fixtures are interchangeable from pipe length to another, so one set can serve several needs.

Thank you both for your replies

I also put a pipe connector in the middle and make them longer.

If your pipe is threaded at both ends, that stainless steel ‘spring’ is actually supposed to be screwed onto the back end of the pipe threads, so that tail end of the clamp does not slide off the pipe when you hold it vertically. I usually only use pipe that is threaded at one end, and those springs tend to get lost easily since they can’t really be put on the pipe if the tail end is not threaded. Ooops, ditto to cant’s answer above!
