Smile, they'll probably only ask you to bend over a little. 
How about all the way over and back around and all the way over again !!
Ok guy's here it goes........ First off they would have to reverse engineer the gear + make an engineered drawing. That means i would be able to take it to any manufacturer and have the gear made. Cost..... $2,000.oo . But after talking to them and explaining what it is for and showing them the R.C. catalog and pictures of the SORCERER dragbike they knocked the reversed engineering drawing to $1,500.oo.
After that there's the process of finding out exactly what material the gear is made out of. 2 way's of going about that. One is sending it off to a lab and doing all of the tests = $ 2,000.oo Or choosing a high grade material and running with it and saving $ 2,000.oo Then having the material, it must be sent out to be broached and bored. Then they will cut the gear teeth, grind and polish. Last, the gear will have to be heat treated.
All in all this venture will not be cheap. Some major time will have to be invested to figure out what the exact price per piece would end up being. Some special tooling would have to be made to manufacture the gears which would be included in the cost ,which would be owned by the customer. That said the customer could take the drawing and the tooling to any gear manufacture and have the gears made. I was taken through the shops and observed all kinds of special machines in operation making some really cool pieces for the military and Boeing aerospace . So there ya go, now to figure out if it's worth the time and $$$$$$ to invest in this and how many people out in the cycle world would need this gear and the timing shaft.
I was just thinking......Can you imagine what the cost factor would be to have all of the pieces made for the R.C.angle drive setup ? I can't even imagine what the larger gear that's in the housing with the special bearing would even cost !
