The ShopBot table at Pier 9 was custom made by Shop Staff to make workholding faster and easier. Treat it nicely.
- Never cut into the table more than 1/32".
- Carefully measure your material thickness to avoid deep cuts in the table.
- See Shop Staff before using screws as a workholding method.
Full Sheet (4' x 8') Workholding
When cutting full sheets, use clamps to hold the corners and edges to the table.
- Square the workpiece to the ShopBot table.
- Use the red and black clamps to hold each corner and side of the material.
- Only use plastic and rubber clamps - no metal.
- Use a minimum of 6 clamps; one on each corner and one on each long edge.
- Use more clamps when possible.
Partial Sheet Workholding
The table has a grid of over 400 holes. Each hole has a threaded metal insert that nylon bolts can be screwed into. The nylon bolts secure the hold down blocks that hold your workpiece.
- Blow out the insert with compressed air.
- Place a hold down the block at on the table, at the back of the workpiece.
- Place the long edge of the block against the workpiece.
- Screw in two bolts, using washers.
- Hand tighten the bolts.
- Use a wrench to tighten an additional 1/4 turn.
- Do not overtighten.
- Place a block a few inches from your workpiece.
- Place a second block on the first, with one end on top of your workpiece.
- Attach them with a nylon bolt.
- Add a minimum of two more hold downs.
