My practice chair just cracked! It's an old(ish) wooden desk chair and the seat has cracked directly up the middle. I don't have a clamp anywhere near big enough to hold it in place to glue it. Any suggestions?

Zip ties.

Tourniquet.

Baling wire (or a coat hanger).

#2 or #7 would work.


When I needed to clamp some wood down for a bookshelf, I used a lot of heavy books (wrapped in plastic bags so they didn't in contact with the glue) and used them as a weight. I imagine that if you put the chairs sideways and then lay the books on top of some kind of shelf you might be alright...

You could try packing tape. Wrap a number of layers around it pulling tighter each time. This may not apply enough force in this situation and will leave adhesive on the seat which will need to be cleaned off. Also it will apply more force in the centre of the seat than at the edges.

One way to glue up odd shaped objects is to glue bits of wood on for the clamps to grip on. The blocks are then planed off after glue-up. Of course this means sanding and refinishing the whole thing.

With some strong and not too stretchy cord, I think you could make a variation on #7 at home. Tighten by twisting with some kind of skewer.

I've used old bicycle inner tubes for this sort of thing.

Trevor,
I can help you out but won't be at rehearsal tomorrow night. Get my number from Big Pete or Harshey and give me a call.

Thanks All -

Got it done. Chair is good as new and should withstand many more years of, um, being sat on.

Try a spanish windlass. Glue first and then wrap a rope around several times to get a firm and wide grip and then twist/rotate the two free rope ends with a stick until you get it tight enough. Tie off the stick with another line until the glue dries.
