Anybody know how much a custom bolt would cost?
#1
I have been completely unable to find the right sized part for a guitar modification. Thought I had it with a Chinese part from eBay, but three weeks later it showed up and still wasn't right. Anybody know what a metalwork shop would charge me for a pair of small bolts milled to my specs?

(Since somebody is going to ask, I need a bridge stud with an 8mm screw and a ~4mm post.)

Do you have CAD drawings?

No, but it's a very simple part. Like this (the screw part only), just with a slightly-larger-diameter post:

Gonna need a drawing to estimate it, or create it.

I'm going to bet that a hobbyist machinist will be TONS cheaper than a machine job shop, but you never know.

If my lathe wasn't in storage, and I had the right thread pitch of die, such a screw would take me maybe half an hour to 45 minutes to make, another 10-15 to make it pretty.

Someone who makes small screws more often than I do could probably make it half that time.

Something like this that you could modify?

Depending on where you live, there may be an active Maker space group that can take care of your needs.

Go to the local high school shop class or skilled trades school. Take some metal stock with you, but not tool steel (something softer).

Turning on the lathe is easy, cutting the splines will cost a fortune.
