In my continuing attempts to hack the Pmaster, I have been looking at the screw inserts in the permanent rods attached to the base. They seem to be glued in, but if i could melt the glue and unscrew them, I could replace the springs with some stiffer ones and up the stretch a little. I want to be careful not to ruin the thing, because i’m not going to buy another one. Anyone know a good solvent for glue?
maybe i’m going against the whole theory behind the thing, but the stretch just seems too weak, and without some feeling that it is stressing my body, I have a hard time convincing myself to wear the damn thing for long enough periods to make a difference. does anyone know how the spring tension on the Pmaster compares to other similar devices?
The Pmaster lit says the max tractive force is 1150 grams = approx. 2.5 lbs. I’ve been using the Bib in the 12 to 17 lbs range. I think adjusting the Pmaster to pull at 5 - 7 lbs with a comfortabe attaching mechanism would be about right for me. Much more convenient than the Bib, but still not something i’d wear in dress slacks.
