Large wood drill bits

I need to hollow out some logs, but leave a bottom in, thus creating pencil holders for the desk.

I purchased a Famag Bormax just before Christmas as I needed to drill about 500 holes of 40mm diameter in beech. I have tried many makes before including Clico and the Famag easily is the best by far. They aren't cheap, but there again you pay for quality. I expect this one to last for many thousands of holes. The critical aspect of course is not to knacker the steel by using too fast a speed when drilling and pulling it out now and again to free up any compacted shavings.

You can still make them on the bandsaw, cut the bottom half inch off, to reuse. As the base, mark it with a pencil so you can rematch, then cut out the circle, switch bandsaw off and take the blade out same entrance cut" easy, I've done shed loads, a fast type of shrink pot:thumbup:

Quoted wrong post , thumbs-up to this idea. [emoji106]

The only thing I keep thinking is that if you make the holders as currently planned, there is a strong likelihood that they will split through at the base when they dry out fully, as anything with the heart in tends to do (even when cut very thin as oysters). I would be far more comfortable with drilling right through (or deep drilling and then cutting off) and inserting a disc in the base as a plug as I think it's far less likely to crack.

depending on the timber you need only drill a small hole in the pith at the bottom of the pencil pot to stop splitting.

Ah delabodge, i understand what you mean now, unfortunately i haven't got access to a bandsaw, so i will have to stick to doing it my way, but thanks anyway.

 

Cheers for the tips about the bottom splitting. The timber will be whatever i can scrounge from the wood at work, so it could be anything.

Found an expanding bit, that i forgot i had. Drilled hole approx 60mm dia and approx 100mm deep. Theres about 40mm of solid timber for the bottom. So i've made 5 just as a trial, if they want any more, then yes i will get tooled up proper for them. Just one question, is it worth giving them a coating of oil or not.

Splash of Danish oil would be my choice.
