Default Drilling large props

Do I need a prop guide to drill my large props? Do I need a drill press?

The best answer to both questions is yes.

And a SHARP drill if you're talking carbon props.

Can you get away without a drill press? Probably but a drill guide is pretty much a must.

Solid carbide bits work well on CF.

I still prefer a brad point drill and a drill bushing. I had a very accurate bushing plate that bolted over the hub of the prop. Keep adjusting until prop balances, then drill through the bushing. Debur both sides of the hole and rebalance without the drill bushing. Very close to balanced just with the drilling.

My comment regarding carbide drills was about carbon fibre props. Unlike high speed or plain carbon steel drill bits, carbide can stay sharp after drilling several holes. The alternative here is solid carbide flat point end mills or flat pointed twist drills .


All using guide bushed fixtures.
Large wooden props are all but ancient history around here now.
