Making Semi Automatic RBG Parts

Since you guys asked me so many times for this, here it is. I have to warn you- if you dont make these parts PERFECTLY, they wont work worth a damn, so you'd be better off buying them in a store on on ebay (like I do).


I would always use some ABS plastic sheet for this, but if you find yourself short on this material, use very strong hardwood (rosewood, oak, maple - hell, ironwood if you can get that [good f***ing luck]). You should plane the material down to 1/4" for best use.

Step 1 COG Wheel: Sketch

First, using a specialty drafting ruler or compass (and anything with 8-12 angles marked on it). Use the ruler and sketch the circle (around 1" in diameter), and the tips of the angles. (as shown)

I would suggest a well calibrated scroll saw instead of a band saw. it had better cornering ;)

[redfoxdude11]

i totally agree with side winder

[MadBricoleur]

[mettaurlover]

[zak.gillies.oo]
