Every thing I see on building rockers and laminating the rockers themselves appears to require a lot of clamping. I think a recent blog suggested having 30 clamps available. If pressure is mandatory, then I suppose the K Body would be the clamp of choice. Any recommendations out there? I’m at least a year out on that project, so I have time to wait for specials and/or buy a few clamps every so often. What would be the best size?....12”, 24”, 31” ???Thanks,

Any clamps will work. I have seen people do bent laminations and used Harbor Freight clamps to secure the laminations.
I used to use, and sometimes still do, use my K-body’s when clamping a two part form.
But since I do a lot of veneering, my best results are obtained using a vacuum bag and pump.

As for the sizes, it really depends on what size your forms are.
My rocker lamination form is 6” wide, by 5” thick. I like to do a 4 1/2 wide lamination, then rip them to 2” wide rockers. That way I know both rockers have the exact same radius.
So if I were to use clamps with my form, then any size bigger then 12” will work.

Hope this all made sense, pm me if you need any more info or maybe some pics.

Hey Don
If you don’t have a lot of clamps you can take several pieces of plywood, mdo. or most types of sheet goods and glue them together so the are as thick(wide) as the rockers your wanting to make and cut the U shape you want in the stacked material .After smoothing the edges you place some packing tape along the edges of your forms and then place your strips to be laminated together in the forms with the glue in between and squeeze the forms together in one of the following manners. screw and glue one side of the form down to a separate piece of ply on the bottom and then on the free end glue and screw some 2×4s or what ever spare wood you have to the separate plywood so that is far enough away that you can place the second half of your form plus some wedges to tighen it up with the wedges. option #2 is to place some sections of strong rope around your form tied in a loop so you can twist the rope with severial large screw drivers or other rod like items to clamp the to peices together while the glue drys
