Get that built up & back here soon as you can!

I was going to say that front triangle looks super like a Cannondale Gemini (of course minus the linkage)

I was thinking the same thing. Its reminiscent of the Cannondale Judge. Looks great!

Very nice. Given it's 7005 have you been able to age/heat-treat post welding?

Hello !
Quick question for steel frame builders here. How do you protect your frame from rust (inside and outside of the tubes) ?
I sprayed a bit of WD-40 inside of the the tubes.
I wanted to keep my frame with a raw look so I just varnished it. But rust slowly appears... Any tips ?
Thanks !

Outside: Paint or powdercoat
Inside: Tectyl or something similar

Not yet, might do that after testing so that I know I don't have to change anything. the benefit of AL7005 is that it cures itself at air temp, but heat treatment is better.

I wonder if somehow you can do clear powdercoat without sandblasting?

I have a pslope and its a translucent red powdercoat overtop a non sandblasted frame. So maybe something like that but without the red. Good luck- bikes rusting sucks I have a steel dirtjumper

made some progress and I'm super stoked on the outcome so far:


getting there with all the hardware. With each part I learn the limitations of my diy CNC and it get s easier and easier.

Getting there with the hardware. This is probably the part i underestimated the most. even if it is just a small spacer ring or something, everything needs to be done and everything takes time.


seat stay moulds finished tooling after the post cure.

seat stay moulds finished tooling after the post cure.

Also got the first carbon moulds done. started with the seatstays to test material compatibility as i used some new things i haven't used before. everything worked out really nicely and I'm ready for the front triangle. Still need to make some more inserts and things like that, but one thing at a time.


seat stay moulds printed plug and some threaded rod to keep everything straight and aligned while glueing up

seat stay moulds Vacuum infusion to fully wet out the carbon fibre with high temperature epoxy resin.

If you're interested there is a full picture series on the mould construction from printed plug to finished mould in my album. And don't hesitate to shoot me a message if you're interested in additional information. I'll try not to spam too much in this thread.

How are you planning on moulding your seatstays?
Prepreg and a bladder? its hard to see mould features that allow this
