This pledge is for a Slotting Head to fit the Bridgeport mill, the example in mind being an Original Equipment type E Head.
What it is
A slotter cuts square edged holes in metal, usually for keyways to hold gears onto shafts or splines, and also allows forming of gears from scratch and v-grooves which would otherwise be impossible by milling.
The ability to make keyed parts would be both a useful addition to our capabilities, and a boon to our ability to repair the other machines in the space.

Success!
In under 12 hours from the start of the pledge drive we reached our goal. As of 14/08/2018 the Slotter has been purchased on eBay, and the sellers bank details passed to the trustees to arrange payment on behalf of the space.
As of 18/08/2018 the slotter is installed and working.
Keen users should be aware that it takes 5/8" round HSS toolbits; the 5/8" size is now depreciated, and the only supplier of new material is Cromwell tools at around £24 per Bar. Steel and hardened set-screws are on-order to build a tool-holder to allow the machine to accept standard 1/2" and 3/8" square HSS toolbits, in the coming weeks.
