|Thomas Organ developed this hand truck style trolley for the Westminster Bass amp. It was constructed from 7/8" OD seamless steel tubing by Technibilt, a Los Angeles area shopping cart manufacturer.
The single 18" speaker enclosure rested on the bottom two tubes of the trolley. The speaker enclosure was not fastened to the trolley, it was merely held in place by gravity.
The amp head rested on the two parallel tubes at the top of the stand. Thomas Organ provided a removable "head security clamp" to attach the head to the trolley. See this part in detail below.
Two 6" wheels were mounted to axles in the rear of the trolley and secured by cotter pins.
The seams in the trolley were brazed, not welded. For this reason, one should not try to strip and rechrome one of these stands. The brazing will dissolve in the stripping acid, leaving a pile of loose tubes in the bottom of the acid bath.
