I would like to see that! 

Change of plans. Caleb informed me that he is making tooling for some off-sized tubes somewhere in between 1/4 and 5/16 that Ned apparently got a metric S-ton of and I'm going with that as soon as Ned offers it in the marketplace. Making my own tooling for the 1/4" tubes but will try the other on the stand first. Making me a tiny support for the 1/4" tubes this weekend so I can use the arbor press and put some whistle in them. Cheap fun!!!


Come on! Name one other hobby in which you cheer as your money and hard work go up in smoke!

May I ask what you use to make these tiny support ?

The tiny one will be made from ½" PVC heated and cut to fit. I'll have to play with it a bit but I'm a plumber and have tons of scrap.

5/8" od x 1/8" wall aluminium tube might work if the tubes are 3/8" od. A few turns of thin kraft can be used to make up small differences.

1/2" emt electrical conduit works perfect for 3/8 tube supports so does a 1/2" sch 40 brass nipple. I like the brass, emt will oxidize and removal becomes difficult.
