Well, I'm starting back from my winter hiatus.

I was going through a dry run glue up tonight and realized that I don't have
clamps long enough for what I'm trying to do. I have the quick grip type
clamps - 36" and 24" variety. But I need to clamp about 40" wide.

I thought I had seen somewhere before how to combine two clamps together to
make a longer one. Was this on the quick grip style clamps or another kind?
Or am I going to have to resort to buying more clamps?

Thanks
