Adding a Quick Change Tool Post (QCTP) to a Grizzly G0602 10×22 Lathe

My first modification after buying my G0602 was to add a Quick Change Tool Post. QCTP’s have many advantages, including quick and easy tool changes, consistant tool height setting, and safety (sharp tools sticking out in 4 directions from a standard 4-way tool post can be a painful way to learn a lesson!).

Anyway, adding a QCTP to the G0602 is very simple, as long as you  access to a milling machine to mill the plate that fits in the t-slot. Here’s a video of the process.

If you don’t have a milling machine you could figure out a way to hold the plate in your 4-way tool post and use an end mill held in the chuck (or better yet held in an end mill holder that fits the taper of your lathe spindle). But you’re best bet is to use a mill to modify the plate to fit your t-slot.

One final thing, your QCTP probably came with a plate to modify as mine did. But my plate was a bit short, so I fabricated my own out of a piece of scrap. Doing so requires you to also have a proper tap handy. That tap size may vary depending on who made your QCTP, but just keep that in mind if you decide to make your own plate rather than modify the one the tool post comes with. I purchased my tap for about $12 from a local supplier (no shipping). You could probably get one for about the same price from an online supplier + shipping. If it’s a size you think you’ll use a lot moving forward, go ahead and purchase a high-quality tap. But if not, go with a cheap tap. I haven’t used my tap since adding the QCTP over two years ago, so the cheapest tap they made was perfect!

As an alternative to buying a tap, you could also single point the internal threads on the plate, but that’s a whole ‘nother ball of wax, and somewhat outside of the scope of a beginner-level modification. But if someone does single point their plate, please post a comment with pictures &/or video of your modification.
