[ryanjohn_5]

http://www.ehow.com/video_4946774_woodt ... -body.html

(check the video, its only about 1m long)

im up to the boring the hole in the body - where would i get a really long drill bit like the one he is using in the video? - does that type of drill bit have specific name?

thanks for your help

sorry the link should now work

The link doesn't work for me. Is there a bit missing?

Its just an extra long Forstner bit isnt it?

Ive used them to bore quite far into objects, you just have to remember to retract the thing every now and again to pull out the chippings, otherwise things get a bit clogged up.

It is a Forstner bit. If you can not find one long enough there are extensions you can purchase. The best value one I could find is from Record Power p/n RPFBS-XT 4" Extension. It is not on their website.

Hi Ryan

Axminster do an extension bar for about £20:

Top tip for this kind of job is to start drilling with the required size to about 1/4" then swap for a smaller bit, this way the drilling will be considerabley easier. Once at depth switch to the original and required size and wizz through the remaining timber. Loads less heat and smoke this way!!!

PS, Just watched the section of video, I'd also keep hold of your drill chuck when drilling!!!

he says to turn the chuck key in all 3 holes to ensure tightness, surely, the whole point of a Jacob's chuck is that you don't have to do that?

I think it's called a pilot hole Richard and I agree with what you have said!!

Danny, are Yanky chucks the same as ours, only need one key?

 

[Richard Findley]

Hi John,

I didn't mean pilot hole, what I mean is if you need say a 35mm hole, start the first 6mm with your 35mm so you can locate it later and then drill out a 20mm or so hole. This will cut WAY easier than the 35mm. Once down to depth go back to your 35mm and it acts like a reamer and has less to remove so is loads easier.

As for tightening in all 3 hole, it strikes me as a bit of an old wives tale to me, I know I don't do it and have never had a problem.

Cheers

Richard

Ryan - I hope you don't make as much of a pig of the hole as your heading !

I was told to hold the chuck so that the morse taper in the quill didn't come loose when I was winding the bit back out.

Hi

check out the latest "woodturning" magazine, there is an advert in there from Colt / MaxiCut Forstner bit.

Have a read they do 90, 150 and 270 mm extension bars which are very good specifically designed for pepper mills sets.

Not sure if anyone else has found this, but I can only get away with a Forstner bit at extremely slow speeds.

Most of the time when I use sawtooth/forstner bits I do as Richard suggests - drill out using a small bit and then work up to the size I need. I don't do it for pepper mills though.

Mark mentions the Colt bits - I have a 38mm one for making Crushgrind mills. It was expensive at £33 but it cuts really quickly. With my old bits (cheap set from Axminster) I had to turn down the speed and really take my time as the bit heated up and clogged easily. I also had to regularly sharpen them as well. The Colt is HSS (I think) so shouldn't need sharpening anywhere near as much.
With the Colt bit you still need to clear the chips but recommended speed is 750-1500rpm and it speeds through the 22cm depth of my design. The 150mm extension was £21 and the locking system they use works really well - no grub screw to tighten and no chance of the bit rotating in the extension/chuck. The end of the shaft isn't circular and locks tightly into place - so tightly that I have to use a couple of spanners to free them. If you want more depth then a longer extension is available from Axminster. I bought from Constable Woodcrafts
