Sometimes the simplest things take a great deal of time. All I wanted was a bunch of lines scribed on a piece of aluminum. Being retired means I can do whatever I want as long as I don’t spend any money. Years ago I made an X-Y table to fit on a drill press. It never worked as it was not strong enough to work as a milling machine. I need eight pieces to fit in square holes on the side of a “O” guage model diesel. The lines need to represent louvers and are fifteen degree slats in real life.
Here is what I made using a support for a dremmel tool. The aluminum square tube was an interesting piece of junk I saw at the steel store. Yes I wasted a buck. I brought it home not knowing what it might become. I used a couple of 2x4 boards and cut semi circles out of the sides at about 15 degrees and made slats to go at the top and bottom to clamp on to the drill press. I used 3/8 threaded rod to hold the whole thing together. T-Y table uses a forty thread per inch screw so that each division of the collar id one thousandth of an inch. I carefully milled the aluminum until I got what I thought might work. I will cut squares out of the section to then glue into holes I will make in the model. Making this by hand using automotive bondo was just too crude and did not work well.
This was a P&F model I got on eBay for fifteen dollars. The pilot was copies from am Atlas pilot and an All Nation F3. The top fans and vent section came from a B unit by Rail King
