Needed some Deep reach C clamps so decided to make some. Figured while I was at it I should build regular ones too. So I built four deep reach and four regular reach clamps. Made them from Black locust I cut up last year using my homemade sawmill ( ). All the joints are 2.5mm finger joints cut on my box joint jig ( ). I used 1/2” threaded rod. Just threaded the wood so I hope it holds up.

They work well. enjoy.

Those are some nice clamps. I bet they will hold up for a long time with those tight finger joints and the extra support of the bolt keeping a lot of the stress off of them.

These look really handy. I’ve been putting off making some until my box joint jig was done, now I have no excuse.

Been experimenting with threads in wood. So far, 5/16” & 3/8” held up well. Hardwoods obviously hold up better than softwood. But even pine held up better than expected. My 1/4×20 threads are stripping easily, not even hardwood or plastic is holding well. I suspect the problem may be my Harbor Freight taps, or maybe 1/4×20 is just too fine a thread for wood.

Rick. I used 1/2 inch threaded rod for that reason. I figured the size of threads would make it last longer. Definately use hardwood for the part that gets threaded. I have used 1/4 inch threads in wood in the past with good luck but only for light duty items.
