Hello World!
First time on this forum, just finished reading rules and guidelines. If i make any mistake, please notify me so i can correct it as soon as possible.
Currently building myself a motorized bicycle using a 42cc chainsaw engine with 2-4HP and an old bike of mine. More or less have everything figured out, except one thing. I am now at the current stage of figuring out what sized sprocket to place on the clutch of the chainsaw. How i plan on doing it is quite simple. First, i get the sprocket, and using a lathe, i will bore out ~29.8mm-30mm hole from the center (The sprocket on the chainsaw clutch for the chainsaw chain is 30mm in diameter). I will also have two rings with the same inner diameter made, and will have both placed on the opposite sides of the sprocket. I will then use a hydraulic press to sandwich all of this onto the chainsaw sprocket. In order: Chainsaw clutch, spacer ring, sprocket, spacer ring. May possibly put a few weld beads between it all to secure it. This will all go back onto the chainsaw, and be mounted on my bike.
Any objections? Any tips? Would this work? Did i post this in the right spot?
Second question, mostly pertaining to the title and the sprocket.
I haven't really worked much with sprockets, so i need a bit of help with this. I need a sprocket that: Has the smallest number of teeth, Has a current bore size of 30mm or smaller, and/or can have the center bored out to 30mm without structurally clasping/ the low end of the teeth getting in the way (Basically, the lowest point of the outer diameter must exceed ~35mm, or a number where if the bore is 30mm, the teeth don't like fall off or something. You know what i mean.).
Chain? I am not 100% of what size i will be using, but lets just say, i don't want to change the sprocket on the bike, however, i don't think bike chain is strong enough to withstand the chainsaw. With that said, is it possible to have one sprocket match the chain size, and the other sprocket be a little bit smaller? I currently don't know what size of chain i am going to be using, so thickness is currently semi irrelevant. Would also like this answered.
So where could i purchase such a sprocket, or at least, what should i be looking for? Number of teeth? All i could find were sprockets with too large bore sizes, or not enough teeth to have a 30mm bore size.
EDIT: Bore size of sprocket can range anywhere from 18mm diameter to 30mm diameter.
