3D Printed Quorn Tool & Cutter Grinder
Pete49:
wow you are getting on with it. Loving it.
RotarySMP:
I like the way you interlock the two components. One of my friends has been 3D printing for a few years, and it is really cool the completely differnet solutions to mechanical problems he comes up with, compared to a subtractive worker (Machinist).
Look forward to seeing how this pans out. You can still lost PLA cast the parts if they turn out to lack rigidity.
Sounds like most Quorns get made as a skills challenge, and end up barely or unused. At least a plastic one won't rust :)

LOL. I think you got it spot on Mark, this is as much a challenge and as such the design will morph as problems arise. Take for instance the vertical part of the casting. To make that more rigid rather than add ribbing to the vertical column I would be better moving the fixing round 90 degrees then mirror it, so instead of one bolt it has two fixing bolts. I am going to try acrylic rod in 25 and 30mm for the bars. The 30mm should allow me to machine in the spiral with some yet to be devise cunning geared gadget. So there goes the idea of not having plastic on plastic bearings.
No worries on this one closing up Norman, it will be printed with the slit or some yet to be thought of bar clamping method. I expect to get none of this right first time and now for some delay whilst I prepare further modelled parts.
Joules:
You already know Norman, my biggest challenge will be when I start building the parts away from the bars and things start to flex. That is where my main concerns are, and if I can devise alterations to stiffen those parts without them becoming unwieldily.

Prof. Chaddock made it as step on the way to his BRM model. See page 31 of this link:
