This is the join for the seat tube. At this stage the hole for the seat tube still needs to be drilled and then must be rounded off. I like the contrast between the greenheart and the ash in this laser cut join.
This is the head tube after the hole has been drilled. After this an aluminium tube will be inserted into this hole to accommodate the front forks and the join will then be rounded off.
This is the hole for the crank shaft, on the left of the image you can see the crank shaft i have cut from the frame of a bike and which will then be inserted into this hole in the frame.
