Dodecagon Symmetry "Cigar" Barrel completed So far, i could only make linear (rod) dodecagon. This was due to precision issues. the level of precision required is quite high, even for Rod dodecagon, for "Cigar" or Taper dodecagon even more precision is required. thanks to recent research, i successfully developed "Cigar" dodecagon barrel. This was my first time making parts from Ultem material (German imported, high quality) since it has ..

Diamond & Ruby machining process developed For a while, i've been researching for multi-facet precision machining. This is a highly complex process requiring utmost precision. ideally 0.01mm precision is required, however, this is very difficult because all the inaccuracies add up. so far, i've achieved 0.04mm precision. i think 0.1mm precision is okay for sale. now i am trying to achieve 0.01mm precision, although this is gonna take muc..

Prototype drawing of 5th gen Ebonite Feed (research log 6/18/23) i will be developing my 5th gen ebonite feed. based on years of experience on my 4th gen ebonite feed, i have found some areas i can improve upon. 1. first consideration is feed diameter usually #6 nibs have 6mm diameter feed. in order to make ebonite feeder more stably with greater durability i've chosen 6.5mm, same as the 4th gen predecessor. the nib is designed for 6mm feed, but 0.5mm diamete..
