Well, I ordered the screws today 7/16 steel , after talking to Roton they informed me that stainless steel was not available. I think the solution for me is to nickel plate for protection against rust. I can do this in my shop, it's actually quite easy.
I also inquired about the tap for the 7/16 -10 and they let me know that it was proprietary shape and that they were not going to sell it to us.
@ Nicholas I'm successfully printing part out but my question is how accurate do they have to be. The overall dimensions are good but it's very difficult getting the receptacles for the bearings to even get close to the proper diameter. (Always Undersized )
@Dannydefe,
Are you going to apply a hard nickel plate or a decorative nickel plate?
Can you provide plating specifications, so I can give your notes to a local plater?
In addition, I'm wondering if I can build up the surface a maximum of .0035" inch to allow a bearing to be press fit.
Roton said that the O.D. tolerance is: 1.0000" to 0.9965".
Roton screws, hardness: low 20 RC.
Qty:3, Dia 1.00" x 36" long lead screws.
Tks!
