Today, I finished making a #ForgedCarbon #CarbonFiber #Baker 's lame. This was an idea I had for a while and finally had the time to realize it.
I first designed the part in CAD, then designed and printed a PETG compression mould for it. A generous coating of waxy release agent, and strategically placed holes for a pin punch allowed for a relatively easy demoulding.
After a lot of sanding and a good few gel coat applications, and more sanding and polishing, I finally have a usable lame!
To hold the blade, I simply drilled a hole for an M3 screw which is glued in place, then found these aluminium thumb-nuts which look rather slick. There is a very slight curvature to the blade holder, and some protruding geometry to prevent the blade from rotating.
I realize I could have used tighter clearances on the mould because a lot of fibers moved into the gap between the two halves during compression.
Fun project!
