Well, I just made a modification to My Jim Smith style platform...about 5 minutes worth.... I liked the twisting shaft to hold the distal end of the wire on The Twister above...never really happy with the double set up...

Used a 1/4" tee nut....forestner drill and regular drill...set the tee nut flush...used a 1/4" bolt and nut into the tee nut and now can hold the wire with compression like they did above.....the little things....priceless
