So I got tired of working on my RSTD on the ground, and had seen some of these adapters floating around, and even seen some for sale on eBay, but figured I could whip it up in the garage while my 3 year old was napping. Materials: 45" of 1 1/4" square steel tubing (left over from another project) 26" of cold rolled steel angle 1 1/4" each side 1 package of JB Weld (yep I'm being lazy) Setup: Step1: Measure 2x then cut the square rail in 4 pieces. 2 pieces 19" long for the side rails. 2 pieces 3" long for the rear lifts. Measure 2x then cut the angle iron into 2 pieces. 14" and 12" Step 2: Mark on the inside of the angle iron, for the placement of the long square rails, rails should be 11" from outside edge to outside edge, equal distance from the ends for each rail (centered?) See picture to see what I mean. Step 3: pick your favorite welding method. Since I had JB Weld sitting around, and the fun square rail I had available for this project would have produced some nasty vapors if I arc welded, I used the JB Weld... (And yes that is one of the reasons my buddies nicked me JB) Weld the long rails to the inside of the angle iron as shown in pics, and how you should have marked out by now. Step 4: if using JB Weld - wait 5 hrs till partially set. All types continue and turn over to set the short blocks even with the ends of the 12" angle iron, crossing perpendicular to the long rails. Weld in place. Now after waiting 24 hrs for JB Weld to fully cure, or immediately if you used traditional welding, you can use a rasp or grinder to clean up the sharp edges. This fixture will now sit under the RSTD or Venture (or several other Mamma Yama bikes that have low engine cases) with the wider section toward the front, seating at the point that the front floorboards are connecting down to the frame, with the long rails close enough together that they catch even the cheap black widow bike Jack's, and the back shorter crossbar with the short blocks on top will contact the frame just behind the welded on eye slots from the factory. This lifts it away along the bikes rails, and keeps it from hitting the kickstand, and the long rails separation keeps away from our bikes soft underbelly. Yay! Now I just need to get it all shaved down so it won't cut me, and I'm liable to spray it over with lineX to keep it nice. Images to follow tomorrow after I load them to my laptop because apparently the site doesn't like me doing this from my phone.
