Re: [SergentEng] RE: S scale is BIG

I think the operational problems with the S scale coupler have been solved. I had to take about 0.002" off the perimeter of the knuckle and they seem to work ok now. There are still some manufacturing issues that mean the sprue on the knuckle is more pronouced than I would like. After the sprue location is filed smooth, the couplers seem to work fine. I don't know if I can solve this problem or not. If not, the knuckles will have to be filed as part of the assembly process. Its not hard or critical, but it takes more time than I like. I had already decided that the S scale couplers would be offered in kit form only. I don't have enough cheap labor (family members) to dedicate to assembly of these. All castings for the S scale coupler will be investment cast from 3D printed waxes. This means they will be MUCH easier to deal with than the old spin cast couplers. I don't suspect you will have any trouble building them, even if I can't get the knuckle manufacturing issue worked out.
