Anyone know to 'shape' main shafts or other shafts for that matter?
I am wanting to make a few shafts for my vintage helis . The shaft is one of those typical two section shafts (narrower at bottom end as it inserts into auto hub) .I have some new Align 600 shafts which can be the 'mould' to use but I need the thin down the narrow part so it fits my vintage heli main gear ( a Quick Learner 30 by the way ).
Does anyone know what to do ? I know someone will say a Lathe but I have no idea how to operate one and what to purchase for the hobbyist at home .Someone have some pointers here ?

Interesting projet!

In my country is very difficult to find row material to make shafts from lathe or cutting machines on axes.

You need to find axes with adecuate diameter and then with a Lathe, you cut the smaller diameter to make that telescopic shaft.

for my Hirobo shuttle, 8 mm shaft diameter, We found a toner cartridge from a laser with that shaft !!! So, We cut it, drill convenient holes and ready to fly !

You can take measurements of your existing shaft..Diameters;overall length and length of smaller diameter. Make a sketch with the dimensions and take it to a machine shop..there's always some small shops around..at least here in the states and have them quote you a price to make a few..they might do it for a reasonable price..get another quote if it seems high.I do a great decending funnel!

Also; make sure you have looked everywhere for the exact replacement part..I used to make heli parts..I found out it's pretty much always better to buy than build..it's very time consuming and if somebody has invested the money for machinery..they need to make a profit from it!I do a great decending funnel!
