You have to pay close attention to the saw blade thickness vs the fret tang thickness. Make sure your doing straight cuts across the fret board as opposed to a slight wavy cut(happens sometimes without noticing). Use superglue for loose frets and wipe away the excess glue quickly.
Thanks appreciate the help
If its the entire slot I would probably use some some thin super glue in the slot and then use another 1x2 to clamp the fret in place. The 1x2 should at the very least span across the adjacent frets to insure that the loose fret is fully seated and level with the other frets.
What caused your loose slots? Is you saw blade flimsy? I use a flush cut saw but use a piece of aluminum channel taped along its length to make it perfectly straight and rigid as well as serve as a depth stop. FWIW, I use the following saw. I already had it in the shop and its kerf works well for every fret I've tried. https://www.stanleytools.com/products/hand-tools/cutting-tools/saws...
Thanks the kerf should be fine it's the saw that CB Gitty sells I think it's just getting the knack for it maybe getting overly eager lol any suggestions for retaining the loose ones where the damage is already done
Thanks I appreciate the help
I use a stew-mac fretsaw, and i have found that my fret slots are "looser" in softer woods ( poplar as opposed to oak) . If necessary I use a little white glue to tighten things up, if its just a fret or two. When all the frets slots are a little "loose", I shellac the FB first to "stiffen up" the slots.
