    Just working on a framelock folder with a carbon fibre handle and realised that the caged ceramic bearing I was going to use and have milled out a pocket for around the 3/16 pivot is going to need some sort of 'race' for it to run on otherwise it'll…

    As said , all fibrous material should be clamped tight against a sacrificial surface , I use pieces of mdf as it’s generally extremely flat but soft so it doesn’t snag the drill bit like chip board or ply board can (and doesn’t dull the bit…

    Drill onto hard surface below the CF, like solid wood or even metal, and make sure that there are no old holes below the hole that you want to drill into the CF...

    Sharp bits and supe glue the hole, leave for 15 minutes and drill again...should be…

    Any tips on drilling carbon fibre and not splintering the other side?

    Tried using a smaller bit first which produces a small splinter but given I'm only using a 2.2 bit for the final clearance hole the splinter damage is still apparent. Tried slow/fast…

    Round 2!

    Wanted to double anodise this and get bronze splashes. Pretty happy with how it came out, although kind of odd it has reverted the blue back to purple.

    Purple is before blue in the voltage colour scale and i had already gone past that…

    Ah, I see now thanks. Re-reading your earlier post I note that you stated to cryo after hardening not between tempers, it was just that the other literature I'd come across mentioned adding a cryo stage between the tempers. Next time!

    do it after hardening not in-between tempers because doing it after quenching transforms retained austenite into martensite which is a harder crystalline structure so therefore reaching a harder Rockwell as I stated before.

    Shing - second temper @ 315C was the recommendations I got from the technical data sheet:




    oliver slocombe - I did the cryo stage in between tempers, are you saying do it after hardening and before any tempering? What Rockwell are you achieving?

    Managed an average 58 Rockwell (thanks to pieinthesky for testing) score using the following recipe:

    1065C 25 mins, quench between 1" thick alu plates, first temper 200C for 2 hours and cool to room temp, dry ice cryo for 12 hours and cool to room…

    Back from the distributer: "Yes the machines are powerful for their size and in fact the AV75 has the same motor as the AV40 – meaning that the AV40 is the more powerful. These motors have 220 W and 1.0A (operating Amps). Even with the most dense and…
