Post subject: | A day in a life -Classical side slots in neck, double wedge. |
Being as I am just developing my hand tool skills, I was a bit apprehensive (read breaking out in a cold sweat) as it came to cutting the slots for the sides in my neck, as I have already put several hours of work cutting head shape, tuner holes, slots etc. and waiting for glue to dry. Having taken a fancy to the double wedge idea for the slots, two saw cuts each side, parallel and straight and in the correct place made me nervous. A router was out for me - having just routed headstock slots I knew there was altogether too much to go wrong, extremely quickly. Remembering the Veritas Dovetail Saw Guide, I did the home made jig thing with rare earth magnets and thin sticky UHMWP.

Well done! I'm about to cut my first mandolin neck joint so I understand the apprehension. |

I used to do the single wedge. Now I've gone back to the 2 mm (or whatever) slot. I think if you had put a metal shim in your first saw slot, then cut right next to it, you would be done. It's the metal shim that makes it easy. Previously (and many times) I had tried wood veneer and it never turned out good. I think that's why so many turned to the wedge system. Try it on scrap, a bit of Pine. Of course they all work, no wedge, single or double. |

Yes, but even getting the first saw slot was still a problem, mirror image to other side, square and 4 degree (in my case) back angle, for my hand skills anyway. And I would be frightened for my saw (kerfed teeth) with a loose shim, so it would have to be attached to the blade (I suppose steel and rare earth magnets would be a solution) I'm a babe in arms comparing my hand tool skills to yours! As I develop, things will improve (I hope!) |

Colin; I always cut my side slots before-tuner slots/head/tuner holes. That way if I made firewood ;I know right away! Mike |

As I develop, things will improve (I hope!) It's not that difficult. First thing to do is to knife mark it. Make sure that's right. Then I use a very fine Tamiya model makers saw (great little saw), going all around and deepening those knife cuts. Do the same with the big saw, a little deeper. Then cut the slot proper. You can use a guide. That's it. if you get that right your home dry. If you get it wrong, convert it to a wedge (I've done that before!). |

Good idea Mike, would have cut down on he nerves! Micheal. thanks for the encouragement. I followed (delcamp) a couple of threads you posted in including including one on this operation (with John Ray's suggestions. Very clear cut - ![]() I normally use a marking knife for all critical cuts, chiseling a start for the initial sawcut. Also bought a Tamiya model makers saw on your post recommending it, as I find the push style modelling saw a bit awkward sometimes. Super piece of kit, as are all Japanese saws seem to be. The one in the picture I bought several years ago during a visit to Japan, Hard point. Only replaced the blade for these cut, not bad for a DIY shop buy. |
