POWERFUL sash clamp needed

G-Man

I need to clamp a number of large items (think 4 inch beams) together repeatedy and quickly.

I am looking for a large powerful sash clamp but all I see is small ones with twist hand operated handles.

I am really looking for something you can really lever together with arm strength.

Seeing as its coming up a blank I am tempted to cannibalise a calving jack or a superjaws.

Sounds like you could make some with beams end stops and wedges, drop in your beams, knock your wedges, clamped.

If you're buying T bar sash cramps try to get goods ones such as Record , as lot of the cheaper one will not pull the timber square and the thread for tightening them is often shorter than the space between the holes which can be very annoying.

An alternative if you are joining 4 inch wide boards is to drill 12mm holes 6 inches apart in something like a 10 inch long pieces of 3✖2 and pull them together with10mm threaded bar.

The clamping strength of sash clamps depends on the thread size. The best , by a long shot are the now defunct Record clamps and their copies which are still available. However, even with 4" beams you should be able to nip them up - no need for massive strength which will probably damage the piece.
