Some notes on the way to an easy-to-make pinchwheel extruder
In which your narrator experiments with ways to make Nophead's GM-17/tin can stepper hack pinchwheel extruder without a lathe... do you want to read more?
I must confess to having gone off and bought a small £165 lathe compared to my spend on RepRap so far its not such a big expence.
Yup, so did I. Cutting on bolt threads goes easily enough that I didn't need Adrian's hinge device to do the job, though, even with my utter lack of fine motor control. :-D
I keep having to tell myself, however, that if I have tools like that the need for them will start appearing in my designs which, for me, is a bad thing because I want my designs to be possible to build without such tools.
C0 Tailstock Chuck £9.95
C0 Compound Slide & Tool Post £25
6mm Spare HSS Tool bits 6x6x60mm (2pc Set) £9.50
That comes under the bits and bobs heading. Along side the 3 4.2A micro stepping controllers for the Big bertha project. They were all at show prices thou ;-) They guy serving me said "I wish I could spend money like that in front of my girlfriend" I said I’m ok she is an Engineer too.
When we move to my house the Solar powerd workshop will have a dividing wall. ;-)
