A very good suggestion, Roger. Some of the cradling is required by 
balanciers not parallel to the rep bodies. I'll try twisting these 
posts first. (I gave the post, heel and jack glue joints a wrench to 
check for failed glue. I reglued 83 jack joints. A round tenon on the 
tender, cut from solid wood and at a 10º angle (?) to the face on the 
tender which butts into the wood. 5 hours under mag visors carefully 
scraping off hide glue off the joint and regluing to the original 
angle, jacks still pinned to reps. All the while thinking about the 
price of a new set of Renner/Tokiwa universal reps.)

If twisting posts is really that easy, I may try it where balanciers 
are parallel to the rep bodies. Ordinarily,  balanciers should be 
parallel to reps: otherwise the straight vertical line from the 
knuckle to the cap gets bent. With maple reps, I'd have no difficulty 
pin-bending the balanciers straight, but not this set of reps.

But I'm also going to try bending the jack pins again, outside of the jacks.

Don't sweat it, Terry. I'm the only one you've got to keep a careful eye on.
