Anyone need machining doing?

Broady, do you know what the cut depth is for a 1" 24TPI die? Just curious how much material would be left on 1.65mm thick Ti tubing after cutting threads.

IIRC it's a couple of tenths over .02. Measure the ID of a threaded 1" headset nut, subtract from 1 and divide by 2.

Ti seems to be fairly hard to source here in the UK

It's nice to have friends in the aerospace industry.

Christ I'd dread to think what that first block would cost! You got any interesting plans for it?

 

[FMJ]

No plans for it as of yet. It sits on a shelf in the garage waiting for some inspiration. A lot of material gets scrapped in that industry for the oddest reasons. IIRC the certification for those Ti billets was misplaced and it was useless. I can get magnesium plate whenever I need it. Someone touches some stock with their bare hand, and it get's tossed in the bin.

I see a crankset there!

Hi ya Broady,

sorry about the drawing, could you rustle me up one of these please so i can go and get some NOS parts please

Just back from my Grans funeral. Saddest day I've had in a long time, but this has cheered me up no end!!
Thankyou

Turned out a stem and made a copper top cap to fit flush in, nice little mod.

Last week I got a set of Paul brakes (Love Levers + Stoplites) from a friend. Went to put them on my DK, and the bag only had 3 of the 4 cable widgets (one goes in the Moon Unit, one goes in one of the brake arms). Made up a 4th one at work on Friday (Paul's is on the left, mine is on the right). Looks simple enough, you say........

Except for one minor detail. I don't have a lathe.


I am quite good at thinking outside the box, however.

drill and a file ?

Beat me to it.

What he said. Hex bar stock, a drill and a file.
