Parker Fly hardtail bridge

Post by Marko Ursin »

I'm new to this forum so a little about myself:
I've been building basses for about 15 years. You can find my work under name MPU in Talkbass. Now I'm making a Parker Flyish guitar
https://www.talkbass.com/threads/winter ... r.1545407/
I have trouble understanding how the height adjustment works with Parker hardtail bridge. Under the bridge are three threaded holes, in the bridge cavity there's three threaded inserts. I just can't understand how you can adjust the height with any screw going to two threaded fixing points. Anyone have a pic of the screws or any info that helps? Thanks!

Hi Marko—welcome!

The Fly hardtail bridge uses clamp screws (#10-32 R&L x 5/8), which we've linked in the Parts page. @marvin Jensen suggested this approach in the early Parker Guitars days, and Ken still uses clamp screws in the “floating neck joint” in his archtop work today! Effectively as you turn the clamp end one way, it turns the other end the other way.

When you turn the screws in the back of the body of a Fly with a hardtail bridge, you are effectively unscrewing the threads of the screw from one of the three anchor points in the bridge, so it's "left-y tight-y" when making adjustments to the bridge height—sort of in reverse from what you'd think!

Hope this helps! Good luck on your project—keep us posted!

Now I get it, the clamp screws have both left and right handed threads on the ends.

Yes! And, @Ken Parker claims that, oddly, the company’s catalog at one point had two SKUs for the same clamp: one labeled L & R and one labeled R & L! :lol:

OMG! Thanks for pointing me there. That's AMAZING!

Marko, you've made an incredibly impressive guitar. If you don't win the winter build-off, there's no justice...

@Marko Ursin's work looks like the closest thing to a Fly I've seen since official production stopped.
Utterly impressive! :shock:
