Joe, these are air positive one direction, spring return. They have 2.5 mm of travel. The end is swagged on them to hold end cap. Thanks for posting. Tracy ------------- No greater gift than healthy grandkids! |

That's pretty impressive. Reminds me of a story I heard when I first started in machining. There was a country that claimed they made the world's smallest drill bit (don't remember which one). They sent it all over the world to show it off. The tour ended in Germany and they sent it back with a hold drilled through it ------------- "Farming is a business that makes a Las Vegas craps table look like a regular paycheck" Ronald Reagan |

It goes on a machine that machines rotors for cars. It raises a cubic zirconia point on an indicator that checks runout. One of the many little projects I make. I am currently making a bunch of guitar roller bridges and rockers for a customer. They go on the Brian May of Queen, style of guitars.

I owned a Guild BHM... 1985, fixed bridge/tailpiece (no trem) referred to as the "Special", and a set (rather than Brian's bolt-on) neck. SHORT short scale... frets get close really fast, and string tension is low... doesn't take banjo strings to bend notes to the moon. Most don't recognize how 'different' Brian's "Red Special" is from any other electric guitar... it has a classical guitar neck profile both on back, and on front... between that, and Brian's HUGE hands, it's easy to see (at least, when playing the BHM) why things Brian was playing... was so difficult for anyone else to manage. Of course, he built his guitar in his dad's garage, from leftover pieces of whatever hardwoods he had on hand... an old fireplace mantel, a chair, a table... The fretboard didn't have a rosewood fingerboard, it was another piece of oak... all the edging was cut from plastic they had around, and made the bridge from a piece of aluminum cut from some old piece of mil surplus equipment, and fitted with the rollers (that I assume you're manufacturing) and the tremolo string-block used a knife blade as a pivot, with a couple exhaust valve springs. I'm thinkin', though, that if Brian had any of Tracy's air cylinders, he might'a found'a way to incorporate them in that unique guitar for something... ------------- Ten Amendments, Ten Commandments, and one Golden Rule solve most every problem.

You're forgetting the Mother of Pearl inlays from his ma's buttons  That brings back memories, I recall reading all the details of the Red Special build in a Queen book as a youngin'. Used to be well into their music. ------------- Stuck Farmer |

Dave, the guy I make these for is big into the history of Brian. I don't know enough about the different styles of them. We have worked on parts for the Red Special, actually had the original rocker and bridge Brian and Dad made. They we pretty innovative in how they built it without machine tools. They are interesting once you see how they work. Thanks, Tracy ------------- No greater gift than healthy grandkids! |
