How to Make a DIY Subplate

Using subplates with your vises can save a ton of setup time. In the modern world, no one has time to tram and probe a dozen vises on the table.

Flux Workholding Vises are designed to be used with subplates that can be quickly loaded and unloaded from the CNC mill. Making one is easy, and will typically result in repeatability on the order of 1 tenth (.0001 inch).

Here's what you have to do to make the magic happen:

Step 1:

Make sure your subplate-to-be is as flat as you can reasonably get it.

Step 2:

Drill 4 holes according to the drawing below. Add a .050 chamfer to each hole. Then tap with a 3/8-24 tap, at least .5 deep. The counterbored holes in the bottom of the vise are sized for 3/8-24 or 3/8-16 button head cap screws.

Step 3:

Screw the Locating Studs into your subplate. We recommend you apply a thread locking compound and torque them to 5 ft-lb.

Step 4:

Add any other features needed for you to clamp the subplate to your machine's table (or to another subplate).
