Absolutely.

This is also confusing, the ER holder is no longer than the weldon type holder as far as I recall.

my tts holders are older so they may have changed, if not changed several times since. without being too technical, i put a calliper next to each and my 1/2" weldon holders are approximately .4" shorter than my er20 holders.
I doubt I have a gib or spindle bearing issue because going to a R8 collet fixes it. I also don't see how a loose gib can cause a squealing chatter because the frequency is too high. Maybe a rumbling chatter?
Anyway, I measured the length of the other ER collets, and they were only 2" long. That extra .5" on McChatterton makes a big difference because the deflection probably increases as the length ^2, or something like that. (I don't think the ER holder itself is bending much, but rather mostly at the TTS/R8 junction.)

If the TTS System is not working for you, you really shouldn't use it - stick to R8's.
Works okay for me. I may have lower standards?

Sir Wilfrid: Be prepared for hysterics and even a fainting spell. Better have smelling salts handy and a nip of brandy.
Christine Vole: I do not think that will be necessary. I never faint because I am not sure that I will fall gracefully and I never use smelling salts because they puff up the eyes. I am Christine Vole.
