The New Method, Part 2

DIY fake wraparound

Oh no! Unbelievable! So the set screws for all the 6 saddlepieces are missing, means all saddle pieces are just held in place by the pressure of the strings. And the contact to the saddle is the drilled part of the string end! I can't believe it....There goes your intonation! Crazy! Is that real or was the created for fun only?

This is why engineers cry.

This is why engineers cry.

So what does the engineer say about this?

The saddles are held in place pretty much by string tension although they are on a slider.

Is the problem in the OP one of not using things as designed and the abuse is prone to failure or is it more of a general design concern?

I feel the pain. It seems that the days of walking into a hardware store and finding the screw you need is over. In the past I remember the hardware guy glancing at a small screw and magically knowing exactly what it was. Now, even if you have a clue to what you need, you cannot find a assortment with what you require. The price of progress I suppose.

Some Ace Hardware stores are still "old school" with an aisle full of drawers of screws, bolts, nuts, washers, etc. It has saved my bacon more than once.

That bass bridge is a correct design! You can intonate the strings by moving the saddles back and forth and fixing them with the little screws into position. And you have a propper distance to the twisted part of the strings. In the right picture all the screws that allow moving the saddles in order to intonate were removed! So you cannot intonate the strings at all. And the twisted part of the string is on top of the saddle pieces which is totally wrong. (plus a player might rip of his hands on the sharp ends) And think about the force forward which is on the small height adjustment pins on the left and right side. That bridge was designed for downward pressure not for such pulling force!

That's how it should look (sorry, by chance that is a lefthanded guitar):

Thanks. I knew the kludge was going to have intonation problems but it wasn't clear to me that it created more problems than it solved. Maybe it is wrong, but on a bass if the thread winding gets to the nut or saddle and you choose not to get better fitting strings, you just scrape off some of the thread with a razor blade or other sharp object.

A hardware store that has a "Fine" thread screw or bolt is rare. Most all are "course" -- the standard course threads. A 1/4" screw has 20 threads per inch - that is course threads per inch. A 1/4" screw with fine threads is 1/4 28tpi. And occasionally, I get someone who needs an odd screw made like a brass 1/4" 24tpi for an old sewing machine.

A store having metric, inchic , you name itic screws in store with personnell in know is precious.

When I was a kid I often helped my dad (great guy...I miss him every day) with DIY projects. He was the Master Mechanic at our city’s fire Department and there wasn’t anything he couldn’t do, from woodwork to electrical to plumbing to gas hookups to window installation. I learned a lot just watching. One of the biggest lessons I learned was to never throw any hardware, screws, nuts, bolts etc away. He had jars and jars of “things”, so when he needed something he had it. I started the same practice 35 years ago and have amassed quite a collection...he also taught me the first song I learned on guitar, but he had different names for the chords. Thanks Dad.

Wish I had paid more attention to my dad when he was repairing farm equipment. Baling wire was on every piece of farm equipment we had. I was thinking, "were all our parents brilliant and could do anything mechanical?" Probably like Einstein said of himself, "not brilliant just passionately, curious."
