Needed some change gears for my Blomqvist lathe so I could do some threading.
At that time I did not own a milling machine, so what to do when you need some gears?
Well you take what you have in the shop and hope for the best.
So here we go...
I started with making four indexing plates. The sheet metal is 3mm thick and came originally from my old 3000 litres oiltank in the cellar. I did cut the tank up and saved the sheet metal some years ago. Now it was handy to have.
Anyway, then I drilled a totally of 861 3mm holes in the four plates. Puh!
Some kind of locking tool was needed, so lets make one!
Two flycutters was also made and a special attachment for the topslide.(And yes I am not a welder)
A special tool to hold the brass gear blank was then needed so I made that one to. (Aint that sweet?)
Everything was then bolted to the lathe and the rest was a piece of cake.
I did make some gears in Delrin to. Tried to make some gears in steel also but that did not work out well because of heavy vibration.
Here are some pics that might give you a hint how I managed to do the trick.
