Topic: Screw sizes on old Rickys .... duh (?) |

I sweating needles here!
Do any of you have an idea what the size (thread size) the screws on old Rickenbacher bakelites (and Frypans) are, that hold:
- The name plate on the head stock?
- The 5 chrome plated (or white painted) plates on the bakelite bodies?
Even my tool shop guy doesn't seem able to find out.
It would also seem that the standarised sizes have been changed in 1936 and again in the 1960's ... DUH!
But the sizes used on old Rickys seem consistant during that period (pre '36 to post '36). But maybe they just kept on using old stock screws (pre '36 norm) or what ever.
Bakelite is not really the kind of material I want to go and try to re-thread to a new size...
Anyone? Thanks! [email]jaydee@bellsouth.net?subject=SG-Forum/Non Pedal/Ricky thread sizes[/email]

JD, I would be interested in knowing the answer to the questions you are asking also. In all my travels, I have never found any screws that would match up with the originals. What a bummer. By all means, don't try to retap the holes in the bakelite or force another screw that doesn't match up. The bakelight is very brittle and will break up. I need 4 screws that hold the pickup down where the heigth adjustment is. Good luck.

JD....
I had the same problem on my old Rick....took it to a machine shop, and although it is really obscure, the size of those screws is.. are you ready for this?...#3-48!!! They didn't have a tap that size, but they ordered it for their own tools, and let me use it for free on my Rick. Hope this helps.

I may seem re-duh-ndant with my screw problem... but now, I just don't seem able to find that size anywhere on the web. I even searched under "vintage/antique-bolts/screws" but nada...
Am I going to have to be so "lucky" and have to find out that 3-48 just happens to be one of those pre-'36 sizes?
Help is as allways appreciated. Thanks! [email]jaydee@bellsouth.net?subject=SG=Forum/No Pedals/Source for 3-48 screws[/email]

Do another search on "3/48 screws" and you should find several sources. Fastener Express was the first site I found, but their images are all messed up, so I can't tell if the screws they're selling are the right ones for your steel.
Good luck on your search.

Finding the right screws for my patent-pending Bakelite had me scratching my head for a while too. I found #3-48 stainless steel screws at the local Ace Hardware store. They were just slightly longer than the originals--something easily remedied.

Billy, Brad and Bob. Thanks for all the input. I did find the screws that Bob describes and I also found a tap for 3/48.
The only problem is, that the stainless steel screws I found, have the classic "round" or "button" head which is a bit higher than what was originally used on those guitars (well yes, I'm picky  ). I am told that what I look for may be called "binding" or "truss" head.
Anyway, one last question. I just asked my tool shop guy what the first number in those sizes meant.. Eg: the 5 in 5-40 or the 3 in 3-48. I know that the second number is the number of threads per inch and that the first number indicates the diameter size, but in what?
Thanks again! [email]jaydee@bellsouth.net?subject=SG-Forum/No Pedals/Screw Sizes[/email] |

J.D,
The screw sizes are arbitary numbers in one-sixtyfourth of an inch increments and begin with size 0 at 3/64" diameter and increase approximately 1/64" in diameter with each digit increase. The numbers run from 0 through 12 and after the size 12 the numbering system begins at 1/4 inch and increases in one sixteenth inch steps (1/4,5/16,3/8,7/16, etc) up to one inch and beyond.
A 0-80 screw is approximately 3/64" dia, while a 2-56 or 2-64 is just a little smaller than 5/64" diameter. The 3-48 screws are coarse thread screws while its mate that has more holding power is 3-56. These are all standard screw sizes commonly available from full service fastener dealers. These dealers also carry a full line of taps and dies for these screws and bolts.
Regards,
John

Thanks John... doesen't really seem to make sense as the numbers do not seem to clearly relate to a real size... but what ever... at least I see where all the guess work comes in .
metric, metric, metric, metric, metric.... I've finally developed a political opinion  !
