Drilling carbon fibre

Cracked a few over the years, its a lottery. My last screen replacement was from Hand Crafted Fiberglass at Blacktown western Sydney. I gave them the fairing, an SS Bevel and they made the screen to suit and drilled it to suit the original fairing holes and then spent 30 minutes polishing the to me invisible scratches in the perspex away. Absolutely fantastic job for less than $200oz. I am not keen drilling screens.
 
I cracked the screen on my Guzzi LM1 the other day, but not from drilling it. It happened while I was wheeling the bike off the lift table. I was in an awkward position because I had to step over some junk that was on the floor near the bike lift. I was also on the right hand side of the bike which felt wrong anyway. The bike started to fall away from me and I couldn't hold it, so rather than fall over with it and land on top of it, I just let it go. I hate it when that happens. Surprisingly the only damage was a smashed screen, busted mirror and slightly bent gear lever. Guzzis are tough old tractors.

Moral of that story: Don't have junk cluttered around your bike lift table when rolling the bike off. Tidy up the bloody workshop.

Did a similar thing loading a ‘new to me’ bike onto a trailer. The bottom of the full fairing bottomed out at the top of the ramp, and there it stopped, no going forward or back and me with one foot on the trailer and one on the ground.

With no one to help me, I stood there wondering how the fuck I could get myself out of this pickle. It sort of balanced, and I tried to get my trailer foot on the ground, which is when I realised the bars were now too high for me to keep a firm grip.

That’s when the fucker started to lean over, an the rest is almost history. Same deal Cam, I just had to let go and dive out of the way, and watch it drop.

Apart from a few hairline cracks in the fairing, it survived pretty well.

A couple of weeks later, it highsided and bucked me off going up MacQuarrie pass. That really fucked the fairings, seat and rear mudguard and my day, ‘Cause I had to load it back onto ‘that’ trailer .... but at least the fairing didn’t get caught!
 
I go back to push starts on track. Right bastard when the guy next to you pushes from the "wrong" side.
I've seen two rows of bikes go down like skittles - and the punches start flying once the legs are untangled.

Carbon fibre. Bastard stuff. John Britten had a local industrial chemist brew him some filler with chopped CF strand included.
He then cast several fittings on the bikes from this. It had to be machined, filed, drilled and tapped. All of which it did quite well,
using normal HS tooling. But the black snot left on machinery was potentially deadly. I'd come in of a morning and the overnight crew of volunteers would have been at work leaving a coating of it all over the workshop. An hour spent vacuuming before I'd want to start work. John was not happy at my dislike of how things were left. "We don't have time for this"
The inlet manifiolds/trumpets/injector holders had been cast in alloy and a set finished. About 1/2kg each. In this black shit, about 150 grammes.
When I got my lathe home - it had been on site - it got stripped and thoroughly cleaned.
