Has received several inquiries about old tuning screws with measurements and sketches. Looking among 10 kilos of tuning screws with calipers is no big deal, it's very easy not to! To get to grips with the problem, I have spent a few working days taking photos and measuring all the replaced tuning screws. There are about 90 complete tuning screws, almost all for notched heads and older than 1940. There are a few tuning screws for flat heads, mandolins, single mechanics and 12-string.
The most important measure is the distance between the posts, the European tuning screws had no standard. Those from the USA always have the same (almost) distance between the posts that are on new tuning screws. In the submenu I have gathered everyone with similar distances between the center on the outermost poles on different tabs. Remember that the holes in the guitar head usually have a little play and that this particular measure is not the easiest to measure on a tuning screw. + - 1 mm can go well!
Has rated the tuning screws as "normal" or "tight". It is a measure of how loose the post is in the bushings, it is not possible to fix the gap unless the bushings are replaced. However, you can always tighten the rivets of the bushings and straighten the post if it is crooked (if it is not in castings like some "newer" Levin). No old tuning screws are as tight as new ones, there is a reason they have been replaced.
Before I send away a purchased tuning screw, I tighten to rivets, straighten posts, clean and lubricate. Tuning screws that are "inverted", with the worm under the tooth, usually get really good as the strings tighten to the gap between the tooth and the worm when they are tuned up. Such tuning screws are older than about 1925.
I have not saved the screws for each tuning screw, what I have is a jar with all the screws saved. I can look for suitable old screws, otherwise it is always better with new "vintage" screws that are of good quality that I send with otherwise.
The pictures and measurements say it all, enter the number on the tuning screw that is interesting. Single mechanics are sold one by one. Click once or twice on the images for larger size.
Those that are classified as "normal" quality I charge SEK 400 for, those that are classified as "tight" SEK 600 and those that are marked Waverly cost SEK 200 extra. Single mechanics cost SEK 50 each, in addition to those that fit Höfner which costs SEK 200 each. Half tuning screws cost half the sum of a complete set. Tuning screw parts under "Scrap" cost SEK 100 each.
If a tuning screw is ordered, I double-check the dimensions before sending it away. The tuning screws are packed in light styrofoam. The postage right now is SEK 48 up to 250 grams in Sweden, half a tuning screw weighs over 100 grams so it will be the same price for both whole and simple tuning screws. The goal is to pack and send purchased tuning screws the same day or the day after.
