Re: 5.3 to th400

Ok so I tried the diymetalfab way...I won't go as far as to call bs yet, maybe I missed something. For starts, carbine burs on that flywheel at 2500 rpm had little effect. Secondly, I followed this photo for reference on which direction the hole should be drilled. Even though I ended up having to use a titanium bit and waller out holes on the flywheel and they look a little more chewed-up than I'd like them they're still not lining up. After 2 days, 2 5.3 flywheels, and 30 bucks in bits, I'm thinking I'm gonna buy a pre drilled flywheel and turn these two into range targets.
