After several years with my PCNC1100 series 3, the ONLY major complaint I have is with tool pullout using TTS and a power drawbar (don't have or want ATC at the moment). Just had a .25" EM pullout ALOT on a relatively mild cut in A36. So, I would love to buy Tormach's BT30 spindle but without a power drawbar, it's useless and I'm frankly a bit tired of waiting for them to provide some relief for those of us cutting things harder than Aluminum. Recently I have found many Chinese BT30 spindles with compressed air drawbars on AliExpress. The dimensions appear to be close to a drop in on the 1100 but I was wondering if anyone has retrofit their 1100 with one? If so, how did it work and fit. Here's the type of spindle I am referring to.
