Been splicing headstocks and stacking heels, then slicing them up and laminating for necks. I'm using tiny pins or cut off staples to stop slippage, but wondering if this can be done without. How other go about this? |

If I use pins I try and keep them outside the final shape so they are removed when parts are cut to shape. I don't like leaving hidden metal pins in glue surfaces as surprises for repair techs years later. More frequently I'll glue small temporary softwood (spruce) blocks around a perimeter that fit between corresponding blocks on the other piece to be glued. Usually use Elmers white glue or a dab of CA. They carve off easily when done . An old cabinet makers trick is to sprinkle a few grains of salt in the glue line just before clamping. The sharp salt grains provide a little gription before they dissolve in the glue and it works pretty good if alignment doesn't have to be pin-registered perfect. Brian R |

Salt works for me too. As does sand. It doesn't take much. |

"Been splicing headstocks and stacking heels, then slicing them up and laminating for necks" Sorry I wasn't clear from the heading. I'm basically making complete necks, cutting slices from those necks and then laminating them together to make lamnated necks. This is the stage I'm talking about. |

1/4” wood dowel placed outside the pattern. This could even be in the tenon near the top surface. Sent from my iPhone using Tapatalk |

Pins like Rod, blocks like Brian or both; sometimes I use masking tape, just depends on the glue up. |

I use a thin pin nailer from HF nailed into the cutout cavity Of CL gtr headstock. For laminating neck stock a flat reference source melamine, is used to glue 3 piece Necks . I have a mini sears biscuit joiner that has also been used, Fish glue is also good for laminating fast tack and in warm weather does not move around like titebond. Mini 1/4in dowel joints can also be used to align a 3 piece neck . Got one from hf or you can make your own jig from BB plywood or ?? |
