This layshaft will be cheapest to produce, but a new pulley must be bought, like from MISUMI corporation, the problem is you need to buy 2 things, the new layshaft and new aluminium pulley. Might not be cheap. With this option, you only need to use 1 original pulley, so saves you 1 piece original pulley, extending original pulley life. the pulley catalog is shown. note that 14 Tooth is the minimum pulley size and it has set screw in the middle of a tooth, the shaft ID is also 4mm, perfect for the Lazer.
Option 2.
New layshaft with peak performance style spline slot. That means both the front and rear original lazer pulleys must be used. Now the question is, how hard is it to get new Kyosho lazer pulleys if your current ones wear out? If the original pulleys can last very long or is easy to get, then this option makes the most sense cause you only need to buy the layshaft.
I can make a 3D solidworks model for both, you guys have a look and vote on it.
Pic 1, Misumi industrial S3M pulley catalog, pulley uses M3 grub screw in between a tooth for lock pulley.
Pic 2. Kawada Sv-10 Aluminium 16T pulley, look how compact it is. will fit great on the lazer layshaft.
Pic 3 Kawada SV-10 pulley side view, notice the slot cut into it. for the 1mm pin to lock the pulley.
Pic 4. Kawada SV-10 Layshaft, its 4mm like the lazers, and the pin holes are 1mm. i have yet to break these layshafts on my SV-10 eventhough i have ran the car for 10 years + and used crazy motors on it.
Pic 5 My Kawada SV-10 Alcyon II, yes thats where i got my name.Notice how simliar it is to the Lazer, graphite saddle pack chassis, twin belts, mid motor, layshaft above the motor.
Can anyone find a similar pulley in 14T?
