Precision Matthews PM 1236 lathe does not come or have the option of a 5C collet closer. I do a lot of high volume work though, so I need the speed that comes only with a lever operated 5C collet closer so I took a gamble and ordered a Collet Closer from Grizzly. This is the one that fits the Grizzly G3004 lathe and only needed a few modifications to work.
