[PSUBS-MAILIST] overlay welding

[hank pronk via Personal_Submersibles]

Brian,Overlay welding is very common-Gamma has overlay weld on the hatch land.  I do fully expect it to warp, but the overlay weld will be sufficiently thick to machine it true again.  I will order some ss wire and weld up a shaft and see how it machines in my lathe before I jump into this.  I can always hang it upside down in a vat to nickel plate it.Hank

 Would not really be feasible to do that, Hank, It's very tough material first of all, and I want to be able to change props to tweet performance.  I don't want some odd ball prop connection that is not compatible with the rest of the world.   You could have the thing machined perfect ( or you do it)  first before you put it on, then machine out any warp-age .  I think you're asking for trouble doing a overlay.  That could warp as well.

Brian,That would be tough because the seat is conical, also it will be much cheaper to overlay weld.  Why don't you make a bolt on axel extension to hold the prop.  machine the axel hub down so it is just big enough to bolt to it.Hank

 Hank,    Why don't you just weld on a stainless ring an inch or so thick and then machine that? Brian

Hi All,I am back to work on Elementary 3000 and first on the list is to overlay weld my hatch seat with stainless steel and machine it down again.  I am building a vertical turret lathe instead of using my flange facing machine.  I am building the lathe as an experiment also for a future project.  My question is, what type of SS wire should I use.  There is a chance that the sub will see salt water.   I need to keep in mind that the material needs to be machining friendly.Hank_______________________________________________Personal_Submersibles mailing listPersonal_Submersibles at psubs.orghttp://www.psubs.org/mailman/listinfo.cgi/personal_submersibles
