Re: Trying to make a gear pump
Yeah, maybe press fit is the only way, I just like that the cylinder pin is surface hardened and probably more smooth and straight than I can make with my lathe.
The gear on the picture is 11SMnPb30 / C45 steel and the pin is some surface hardened steel (so hard you cannot machine is with HSS).
Brazing could be an option if a suitable filler for steel could be found, I've never tried it or seen it done.
