Quick recipe for a capture rig. Get some 3/4 inch bar stock, about 6 feet long. Make a right angle bend at 3 feet, another 10 inches further, another 16 inches, and the end should match up with the original bar, looking like a giant "b". Attach where they meet. Drill a 1/4 inch hole in the long end and drill a smaller hole perpendicular and into this. Tap that for a set screw and grind the edges off the end. take a piece of 1/4 inch HSS round stock and grind a flat scraper tip on the end. Insert this into the hole and set it with the set screw. (you can also grind the tip half round and make a holder like the Sorby multitool) You now have a basic capture rig. Use a couple of pieces of angle iron welded horizontal and parallel, and 7/8 apart to a frame and with a base post to mount in a second banjo for the capture part of the rig.
From there, you can add pipe-fitting attachments to hold a laser, a threaded end for bent tips or extensions, shaped tips, etc.
Total cost, about 30-50$ and 2-4 hours work with a vise, grinder, and welder. Not as nice as the Jamison but a dang sight cheaper if you're poor like me.
Good luck,
