Oh no! You're just about ready for a big glue-up when you discover your pipe clamps aren't quite long enough. Do you have to buy a whole new rack of pipes just to gain a few inches?Absolutely not. Buy pipe couplings, instead of new pipes. These couplings come in short lengths and are threaded on the inside. Connect your too-short pipes with the couplings and you'll have more than enough pipe to do the work.--from the WOOD® magazine shop
