... line mills have a price card of over 1000 euro's...not yet. Probably i will save money for a good lathe to make some parts for live steam locomotives. I could put my router into a jig but the smallest cutter i could find was 4mm in diameter, to big perhaps? This is how i cut out the sections where the flanges are going in, with a guide to hold it into place. For cutting depth i use the lines of the multiplex sheet, this is with the first saw blade. 3669_261039_300000001.jpg The second saw blade i use is a much finer one with no corned teeth, just flat teeth and hand work To cut out the slots for the aluminium strip and trim the edges i use a jig and my jig saw: 3669_261039_290000000.jpg I can make a frog within 10 minutes with this method. But would be the frog any good, that is troubling me, before i am going to cut up some good material for the bin or derail a expensive live steamer. Please look for mistakes or improvements and tell me ...
