How to make stab-adjusters.
I like to use stab-adjusters to attach the stabiliser halves to the fuselage. The origial units (at least to my knowledge) from Gator are nice, but I do not like the imperial threads. Other clones are not so nice, so I decided to make my own. It's not that difficult, but it requires a small milling machine and some related tools. To make it work properly it's vital to get the correct type of set-screws. Basicly there are three types available; with a pointed tip, with a 'cup' and with just a flat tip. The ones to get are the one's with the 'cup' type of tip, they gives the best grip to the aluminium bar that goes through the fuselage.
As usual I let the pictures speak :

20mm rod
Here
the main shape is milled, and the oblong hole is beeing made with a 4mm milling
tool.
All of the 'upper' part is
milled, the mounting holes are drilled so what is left is to cut it loose from the
rod.

all.

on the side of the wise to drill holes for the adjustment screws.
The
threads are beeing cut, a slow rotaring drill is suitable for this.
