Hey everyone! I'm looking for some guidance on how to drill a hole 32 inches deep with a diameter of about 0.32 to 0.4 inches through wood. We need to keep the drilling perfectly straight, and honestly, it's been quite a challenge for us. We're working with large logs and can't cut them in half to make it easier. A few specific issues we're dealing with are: finding a drill bit that's long and strong enough, figuring out how to securely hold the logs in place, and identifying the best tool for the job. We're even considering investing in a lathe or other equipment if that would help. Any tips on ensuring the drill goes straight would be super appreciated! Also, apologies if my English isn't perfect—I'm using ChatGPT to help with any mistakes! 🙂

You could look into using a snake drill, which comes in various sizes. It’s designed to maintain straightness over long drill lengths, making it ideal for your project.
If you go this route, just make sure you have enough power behind it to handle the depth!
Consider starting with jobber drills to get the hole initiated correctly, then use extension bits for depth. Another option is to rout channels on opposite faces of the wood and then rejoin them, but that depends on whether you can make those cuts.
That's a clever idea! If the hole doesn't have to be perfectly round, a dado stack on the table saw could also work.
Routing is definitely a viable option; I’ve done that before and it turned out really well!
I think the best route could involve using gun drills, which can be found up to 48 inches long. You'll want a drill press to keep the workpiece straight and raise the table progressively as you drill. This method should help you achieve the depth you need more accurately.
Good suggestion! Just make sure you use some type of fixture that holds the piece securely, and don't forget to clear chips out as you drill.
Also, you might want to try using extensions or bushings to help with the depth control!
Sounds interesting! I haven’t used one before, but I’ve heard they work well for deep holes.
