When Cylinder Heads won't fit your gearbox..

Dunno if this is the right section to post.... Transfer if needed...


reinforced gearbox V2


How it looks from the inside... take note the angle.. This is a Stainless Steel Guarder V2 cylinder head with double 0-ring
(NOTE: after buying this expensive cylinder head, we realized that the Area 1000 easily fits... The added hassle for SS, double 0-ring and flat full surface rubber pads.... hahahaha)


use a rotary tool (Dremel, Black and Decker, even the Cheap China made one's are ok.. just don't over work them)
grind at an angle... use a little lubricant to disperse generated heat... (ALWAYS WEAR PROTECTIVE EYEWEAR)


Check the work... Do not over increase the hole size


Finished work...

Sorry for the poor quality pics.. was just using an erickson k750i phone then... (till it broke and now use a k610i lower model phone)..have not gone back to photography and the digital SLR...

hope the info is useful.. (

Again, useful tutorial. I'm seriously considering starting a new section just for FYIs and Tutorials. Keep up the good work.
