donmarkey Posted August 24, 2014 Report Share Posted August 24, 2014 I do. But it isn't cheap to do. For three you are looking at $315. Thanks Don Quote Link to comment Share on other sites More sharing options...
spec4 e4 Posted August 24, 2014 Author Report Share Posted August 24, 2014 Ouch. why so much? Rob Quote Link to comment Share on other sites More sharing options...
donmarkey Posted August 24, 2014 Report Share Posted August 24, 2014 Parts are $30 each unit and at that price I am making about $25 an hour. Less than I make at my full time job. They are labor intensive. First you have to strip and anneal the shroud and make a plug for the rear on the lathe. Then drill and tap for the pivot screw. Remove the plug and open up half the pivot hole for the shaft clearance. Then reinstall the plug and cut the 1/8" slot for the wing. Next cut the side clearance with another cutter. Then for the hand fitting. Each step takes a difference setup with different tooling. And each shroud is different enough that hand fitting is necessary. On top of that I have over a grand in jigs and tooling. And the slot cutters only last so long. I prefer 3 position units nowadays as they take 1/3 of the time to install. Less than double the cost in the long run. Don Quote Link to comment Share on other sites More sharing options...
