We have an engineering club at my high school. Our current project is to build an electric go-kart from scratch, welding the frame and all.
We have motors that come with a D-Bore 10mm shaft, with a 10x8.6mm 11 tooth d-bore sprocket for an 8mm chain (for example, it has the sprocket that is listed as #SPR-811 on this site). And, we have an axle that is the typical 1" key style. We are trying to find a Sprocket Hub (we don't really want a freewheel clutch - fixed is fine we think because we can go in reverse) that can accept a sprocket for 8mm chains, for example like the part number SPR-844, SPR-844B or SPR-844C.
I don't see sprocket hubs on this site that look like what we are seeking, but the ones that I find on other sites don't have the correct bolt pattern to accept any of the sprockets listed above. We could try to modify them, but the holes have to be just about perfect...
Any advice is greatly appreciated! Or, if there are options to modify any of the 8mm sprockets with the correct hole pattern for a part similar to, for example, one like item #138291 on NorthernTool.com - then that would be awesome.
Thanks ESP! We created a hole drilling template that we are going to try using on two of your # SPR-844's. If anyone is interested it in, it is attached as a pdf.
