Sturdee

Following on from making the Sturdee Handscrew Clamps I made some mini clamps to fill a long standing need to have some lightweight clamps (for glueing decorative mouldings etc.) which I could use without marking the work or needing six hands to hold the moulding, metal clamps and wooden blocks.
They are of a similar design as the handscrews, but smaller, and only uses only one screw handle. In use the opening is preset prior to clamping by adjusting on the rear bolt a wingnut to the thickness required and then holding the clamp handle in one hand spin the clamp with the other hand until the correct size is reached. Slide over the work to be clamped and tighten with the handle.
The clamps have a jaw length of 200 mm of 35*22mm with a clamping length of 100mm and a jaw opening of 80mm and are made of some hardwood flooring offcuts. The handles are again made of pine being 100mm of 25*25mm pine rounded over with the router.
The first photo shows the items needed for one clamp, being 4 blanks to make the jaws, a handle, a 225mm length of 5/16 threaded rod, a 6 inch threaded bolt (if not available adapt more threaded rod), a small nail, a T-nut, 4 washers (one of them an extra large one), a Nyloc nut, 5 ordinary nuts and two rubber tips.
