Afternoon all,

Is there anyone here who could knock me up something like this?

I need the silver ones, I have the black ones.

They are for a Trek Sawyer and allow a 29+ tyre to be run on the rear.

Thank you!

Paul

Another view:

I can’t, but if I was asking, I’d start with porterjamie off here and BETD/Goldtec.

give goldtec a ring.

And the original dropouts:

Good call chaps- will drop them a line.

I’m guessing you don’t have any accurate drawings for the silver dropouts?

I could do it, but I’d either need some accurate engineering drawings, or the dropouts so I can measure them up myself to make said drawings. Either way, drop me an email (in my profile).

Ooooo.Can i be cheeky and ask you to make me a pair please.
Will mail you now bud.

MikeR on here had some stuff cut from flat steel for a crazy low price

But those look a bit more 3D

My steel dropouts (referred to by ampthill) were done by CNC plasma – tidy on one face, bit ragged on the back side. No problem if you are brazing and painting but a bit ugly for this application.

Lots of ways to make them.

If I had a pair to draw round, then I’d seriously just hand cut from plate. Then get a friendly machinist to do the tapped holes nice and square. If you add up all the time involved (measure, draw up in CAD, email profiles for quote etc) then it is often the fastest route for a small, simple one-off.

If you can draw them up in basic CAD then lots of places would waterjet the profile quite cheaply. Then just need the tapped holes as above.

Or full CNC as originally mentioned.

This dropout (both painted steel and bare aluminium bit) was cut by hand in a very short amount of time.
