I am working on a product for the CNC router folks. That includes me of course with my HB2 system. The one big pain in the ear for home and hobbyist is the screaming router noise for several hours (or more) at a time. I wear ear plugs but I am sure my neighbors are wondering why that high pitched motor whine noise, is running so long.
My solution is a simple adapter plate to mount the Taig ER spindle and motor to the HB2. Top speed is 10,600 rpm but that is not too bad for the up to 3/8 inch cutting bits I will normally be using. What I like is it features one of the best small collet systems in machining, the ER16 style.
I intend to offer the complete spindle setup in my web store. This will include everything (motor, spindle, pullys, etc.) to install it on the HB2 or any overhead router machine. Price will be < $350.00 USD.
