Without question, Bessey K-body clamps are superior; however; 3/4 pipe
clamps will also do a good job with a little practice.

Contact a pipe distributor and get a quote on pipe nipples.

Just recently bought some 3/4 x 60" long, black iron nipples. Price was
about $15.00.

Add some couplings and you have a lot of flexibility.
