This is how I do these builds so if you have a better way thats awesome... but make your own video please because its confusing those that want to learn when you "experts" argue with my methods... I do the saws this way for a reason and they are runners... and reliable... I have the real world results to back it up... jvust saying...

Thanks for watching!!!
