I have moved my vacuum setup permanently to my CNC so no longer need these.
I would like to offer up the following donation of vacuum chucking items to the woodshop.
A 3 1/2" and 5 1/2" drum chuck and the spindle vacuum adapter. All you need is the guage kit, vacuum pump and hoses and some neoprene rings and you’re all set for vacuum chucking on the lathe. These have a 1" 8TPI adapter on them where that were for my lathe but can be changed out for larger spindles.
Here is a link for more info: OneWay Links
IF the woodshop does not want them, I will make them free to any member who wants them. Plan C is to scrap them. Just let me know and I’ll drop them off the next time I’m in (probably Friday). cheers!
