Hi ya, dont know about all the other modellers, but Ive used a mini-drill to make small items such as capstans, small light fittings, bollard posts, and a few other items. What I normally do is manufacture these items out of either a hard wood, or a brass up to the diameter of say 12 mm - 1/2 inch & the procedure I use is drill a hole through the centre of the item I am making, thread a 6 BA bolt through with a nut at the other end, clamping the work piece between them and then place the end of the 6 BA bolt into the collet of the drill.
yours
aye
