You can see some of the buckling problem I am having when folding the metal over. I think it could be solved by using a hand-held backing stick behind the metal while using the metal tool on the front to compress the metal, but my mandrel is so close to the chuck jaws that I can't do this. I remove the piece from the mandrel and trim the excess away. When spinning I move the carriage over in steps closer to the chuck as the spinning progresses. 18-Nov-2014 First spinning operation completed, ready to be removed and excess trimmed.

I would recommend a mandrel which is not chucked so closely to the jaws like mine - it puts your fingers and the tool too close to the chuck jaws. Aluminum disk with wax lubricant smeared on it, clamping block held in tailstock. Improvised tool rest clamped to the cross-compound. Lubricant wax (toilet bowl wax ring seal worked the best). Forming tool stuck into a scrap piece of three foot long stairwell railing. 18-Nov-2014 Here's my metal spinning setup in my metal lathe for the piston covers: Steel mandrel chucked up.

After purchasing a 13/16" crow's foot, 12-point, flare nut wrench of 3/8" sockets, we find there is not enough room inside the casting to swing it around and tighten the nut. Bill bought for me an inexpensive 12-point combination wrench that we were going to heat and bend around so the wrench would work. Using the crows foot wrench as a guide, we mark the opening size on the box, which will turn it into a flare nut or tubing wrench (you slide the wrench over the tube to get to the nut), I use a fine 6" cut off wheel in my hand grinder and cut the opening in the wrench. Hey!, we don't have to heat and bend the handle! The wrench, when used from the top, can reach the nuts and we tighten them home. Another vexing problem solved: tighten the flare nut fittings.

We worked so hard to fabricate and fit them that I'm not going to scrap the whole assembly quite yet. From the looks of things, one hole was caused by a rod strike, and the other had the weld puddle contact it. I spend an evening with the Dremel and some sandpaper cleaning the plate and all around the tubes for a clean fit. Not an easy place to work in, inside the cylinders. 19-Aug-09 Shop night 4 on this manifold assembly and now we're patching holes in two of the brass tubes.
