The uk qrp club published a design to hold smt parts using a spring loaded
knitting needle. Lets try ascii art
So we have a base board say 6" x 4" x 3/8" (I think 150mm x 100mm x 10mm)
Cut a "L" shaped piece of similar material (3" x 2") and mount on the base
board, so we have something like below (bit like sewing machine arm). Take
knitting needle or similar rod with tapered end. Drill hole in end of L and
feed needle through. Fit spring and collar so needle will hold part in place
on board placed underneath...
I -> knitting needle - lift to place

Hope this is enough to build....
I tend to use locking forceps ....
