Welding sprocket hub into rim

[Ebrownie]

Ok, so I am working on a plan to make a shifter kart with a Honda CR80 engine. I got some nice 16x6.50-8 Tires and rims(for the rear wheels), but the hubs are really wierd. They are 3 hole with a 3 1/2" bolt circle, but the bore is not keyed and is smaller than my planned 1" shaft (live axle). So, I need new hubs, but I can't find any that fit it. So, I measured the diameter of the hole in the center of the rim, and it is 2 1/2". I found a keyed 1" bore hub for weld-on sprockets that has an outside diameter of 2 1/2", which should fit into the rim perfectly. My question is, if I welded that to the rim, could I get it centered perfectly and would it be strong enough to hold?

Here's the link for that hub.

I'd use 7018 and yes it will hold the centering part is on your abilities

I saw the link it even recommends 7018

Ok thanks. I was also thinking maybe I could cut out a hole in a plate and then weld that hub onto the plate and then just bolt it onto the original bolt holes.maybe I could bolt it on and weld it to the rim for more strength. Either way, those hubs should work well I think.
