All tacked up.

Got the new jig all set and the 2nd frame all tacked up last night. Next is to do the brake and chain stay bridges, then onto a layer of fibreglass (only around the metal parts) then carbon fibre!

Getting a jiggle on

I decided to splurge out on a better jig, as the home-made setup I was previously using was a bastard to adjust and get everything level and straight. So I ordered some Maytec aluminium extrusion and components and now have … Continue reading

Bamboo Bike #2 – The Daisy

The second bike is underway. She’ll be a similar vein to Maisy, but for a friend named Daisy. I’ve got the front triangle mitred and the drop-outs are being laser cut. Progress!
