More details on what I'm building below.
I need something to hold 3/4" plywood in place sturdily enough that I can keep my angles correct and mark it; but loosely enough I can take it apart easily.
I could drive screws in and then drive them out and then drive them back in again, but that seems inadvisable, and it wouldn't work where I need to mate the edge of the plywood to plywood (it'll be glued).
I know I could use an 18-gauge nailer but I am wondering if I could get away with a pin nailer instead, since it'll be easier to pull the boards apart that way.
Will 23-gauge pin nails work?
Presently I do not own a nail gun of any type (or I would just test it) - I'm going to be buying a nailer for this job.
Project details: I am building an awkward shaped cabinet (rough design below) that will sit on uneven ground. It's 55" tall. My plan is to build it 'in-place' (i.e. taking measurements on how things actually line up and are level rather than calculating and cutting beforehand).
It's made out of veneered 3/4" plywood, 1/2" plywood, and some 2x4" and 2x2"s in unobtrusive places. I need some way to hold half the pieces upright and in-place while I draw marking lines and take measurements. Then I need to deconstruct it, jigsaw out curves in a couple places after it's been marked, stain it, and then re-assemble half of it (permanently this time). Then I can measure, cut, stain, and put in the shelves.
