When gluing the components usually have to be tightly pressed against each other for a long time. To apply for this clamp is not always convenient, especially when glued with thick objects. So I made here a mini-press. And it serves me for many years.
Mini-press: 1 — bottom plate (channel 50), 2 — bolt chain 3 — chain. 4 — eye (or hook), 5 — nut, 6 — clamping the screw.
As its main element — clamping screw — used plumbing valve with valve and shank at the wrench. The length of each segment krupasindhu chain a little more turn of the screw. Eyelets for attaching chains welded, although instead you can use regular bolts, passing them through both shelves steel channel clamp bar. Better yet, fit the hooks that you can use to enhance any chain link, then no need in a large course screws.
