I bought my 1100 off the company I worked for must be 5-7years ago now. Unfortuntely, after I had paid, but before I picked it up someone (I know who but couldn't prove it) stole both the 8" rotary table, and the duality lathe. So I have a number of bits and pieces relating to those two items that have been taking up space for some time now. I am asking well under 50% of new price for everything. As far as I know none of the items has ever been used and all are in new condition. I guess it's possible that the 5C chuck was used on the duality but I don't think the duality was ever used so it's not likely.
5c collet chuck w key $100
8" rotary table installation kit ($300) $120
3jaw chuck w backing plate, int and ext jaws and key ($350) $150
4 jaw backing plate ($84) $30
misc duality lathe bits $20
live center set ($75) $35
8" rotary table tailstock ($170) $80
I've taken prices off the Tormach website (prices in brackets) or if not avialable - like the 4" backplate, I've taken them off my machine's original invoice. The 5C chuck and duality bits I've just put down a number since I can't find reference on the Tormach website, although there is a 5c chuck plus mounting plate for the rotary table for about $500.
All prices are PLUS priority mail (or other if you prefer) shipping. I guess Paypal would be the best way to pay. Pickup in SF Bay area definitely encouraged!
