Still avoiding Elvis I have now made a start on a few jigs I will need in the future. I find jigs are so important as it makes life so much easier, especially in 2mm scale.
The first came from the need to get my Q1 running much better. One of the main problems with the engine is the driveshaft I originally made isnt really a very good one. Its made from a length of steel wire which has loops bent on each end of it, the problem is the loops arent really good enough so it causes the driveshaft to run unevenly. I have decided to replace it with a new driveshaft made from 4mm scale handrail knobs...
Firstly the handrail knob has a piece of brass rod soldered through the hole for the handrail. The hinge has been modified with a few holes. The larger hole (without the chamfer) holds the handrail knob in position, the hinge is then closed (the chamfered hole sits ontop of the 'sphere' of the knob) and a 0.4mm drill is then drilled through the entire handrail knob. The brass 'handrail' rod is then inserted through the holes in the brass spring clamp and then filed to length.
This shows the final driveshaft before soldering to length (I dont know the length yet) The driveshaft is a short bit of spring steel (guitar string)
I have also made a start on a small jig for soldering up the point rodding stools (as shown in a previous post). This has been bugging me for a while now as I wanted something easy to use as there will be quite a few of them to do. Its proving to be a bit of a toughie as the things are so small!
I have been machining out a recess in some GRP to hold the stool in position, the idea is to layer these up depending on how many stools I need in parallel. The recess is two slots roughly 0.6mm long by 0.1mm deep. The slot drill is 0.5mm in diameter.
The photo above shows a point rodding stool being test fitted into a slot. It seems to be a snug fit, lets hope it works!
