I'm doing a few cutting boards a month and everytime I change up my glue up process. I saw some youtubes of guys using PVC pipe as a base and then clamp across. Tried that and worked alright. Some cranking levers got in the way.

I've also used some aluminum blue clamps from Rockler and laid the board pieces on that. Worked out alright. Neither way have I gotten one board totally flat, all have needed belt sanding or trip to a local shops wide belt sander.

Enter, parallel clamps. Are these worth it if I'm mainly doing cutting boards? I'm mid 30s and woodworking is only a hobby.

I was going to offer $150 for 5 jorgensen cabinetmaster clamps, being sold locally. some 48", 31" and 24" lengths. Will these improve my glue up process that much?

I've bought these a while back but haven't milled the wood to make them yet.
