Thread: Wood work question

Whatcha building, Lou?

Hi, a hole saw will keep running off due to one side of the saw grabbing first, if you pre holes sawed a hole trough a wood wedge and clamp this in place it will act as a jig, and this will stop it taking off...or a spade bit may work if you can hold it in place....all this would be best done with a hand held drill and not a drill press...IMHO

Sorry if this repeats what was already said ...so many answers came through while I was typing

A hole saw will give you a good hole, at that size the only other things that would do it in one go is a fly cutter. Both will require care when used at an angle and will only work without angled packers/jig if you can get the center drill started before one side of the cutter comes in contact with the timber.

If you can mark the hole you need you can use a twist drill and make multiple holes and then join the dots with a round rasp, a jigsaw, small chisel or a hand held coping saw such as this



it will come down to how much time and money you want to spend and how neat you want your holes.

Use a Forsner bit on your drill with the table on an angle.

Here's what I do,
1. Drill a hole at required angle to act as a guide/pilot hole.
2. Remove pilot drill from hole saw and insert length of steel rod long enough to act as a guide when hole saw is at required angle.
3. begin cutting hole slowly until hole saw will guide itself.
4. don't forget to have beer handy.
5. complete job, have said handy beer and admire your work.

I have used this method countless times whilst building the boat and installing pipe work in hard to access areas, works a treat, if the hole saw bottoms out during the cut just chisel out the waste and continue

as Garry said, if the timber is on an angle, then the teeth of the hole saw will bit first before the pilot bit will engage the timber, this will depend upon the angle to be drilled. Another procedure, if the timber allows, is to drill the hole at 90 degrees, then set up a saw to cut the angles you require, either with a bench saw or a hand held power saw with a guide. I hope this has helped to confuse. cheers, Phil

Well I bought a 90mm hole saw today and what can I say what a quality bit of kit I got for 10bux

Drilled one hole to make sure it would be the right size to start with, and it was

Had a go at drilling the actual piece of wood and the fellas were right it was too thick. There wasn't enough depth in the hole saw and well the pilot bit broke off hahahah

Had a crack at doing it on an angle by hand as a practise, it went half way in and actually wasn't to hard to start thanks to the pilot but would not go any further through the wood than half way.

I think ultimately I could do what I wanted to do but probably need to spend a bit more money on the hole saw itself, I don't plan on doing that so I will just drill a couple of holes on the right angle and and forget the angled holes altogether I think.

It's only for a bit of fun anyway

you can now send a piece of the timber ,With a drawing no smaller than A4 to all the wonderful Aulro members who have helped you.
Remember, no smaller than A4 size as some of them can't read smaller print.
the resulting specimens will be posted here, by said "helpers" and you will get to choose which one you would like to keep.
in fairness this will be exchanged for a bottle of cheap red wine from BiLo.
that should cover it then.
