This is what I use. Very important to keep your hand away from the gear teeth while turning crank...
Great video for all the noobs Bart....Did a quick video to demonstrate how to accurately drill holes in wood with a hand drill.
My Porter Cable cordless drill doesn't have a very high RPM range so when it really matters I use a pneumatic drill that is probably three times as fast. Using what you have isn't always bad if you know how to use what you have!
Feel free to discuss, input from the membership is always appreciated.

The fiberglass trick does work, particularly on small planes and glow planes but on larger firewalls its always best to pin or screw. The firewall can still come loose inside the structure if the original glue fails. The FG will however likely give you enough time to notice that you have an issue before your firewall and power plant exit your cowl.
Even with glassing on larger planes, some 9/16" servo screws in CA hardened holes work well and only take minutes:View attachment 11906
