We have two of these at my Men's Shed, I gave them serious thought but decided their accuracy was a bit suspect, although accuracy in this field is not that important. The deciding factor was the centre screw makes doing small depth holes impossible.
Good idea though, thanks.

Does McJing's have a 1-1/8" saw tooth bit?
Mick wants to cut a 1-1/4" thread so needs to first drill a smaller pilot hole.regards from Alberta, Canada

Sorry Ian, and everyone else, I hit the wrong number, I meant 1 1/8th bit. I have the same spindle thread on my Laguna and I cut my own threads for accessories on my metal lathe, so I know the pilot hole is actually 1.128 inches, so a 1 1/8 bit is close enough for timber. This UN thread is mainly used in the American market. I had a look at one of those Beale taps when I was in the US recently, but decided I did not need another toy.
Rgds,
Crocy.

For almost all thread systems, the "official" pilot hole sizes provide about 75% of full engagement. Smaller engagement of 55-60% is often satisfactory for strength. Larger engagement can lead to broken taps, and is not encouraged. In timber especially, "close enough" really is close enough.
Cheers,

If you buy a second hand drill bit it will save you a fair bit, try ebay.If the taper is wrong just get it turned off down whatever you want , it wont be hard,this is a fairly common practice and as stated metric or imperial for wood near enough is good enough.

As I do about 90% bowls a chuck is always on the lathe, and I have a drive center that fits into the center of the chucks for spindles. Oneway chuck system.
If you have a chuck, you might just turn a spigot that fits the most used set of jaws on the chuck, rather than drilling and tapping. I have sanding disks, padded disks to hold the inside of finished bowls for bottom finishing, face plates, big cone drives, small female cone drive to hold tubing, etc., etc., all with a spigot that I grab in the chuck.
Happy and prosperous New Year to all.So much timber, so little time.

The drill bit I ordered online arrived, total cost delivered to me was $10.16 AUD. This was quite lower than I expected, pleasant surprise to be honest. I wasn't too worried about steel quality as wood is certainly not as hard as steel and I would think anything I'm going to be drilling should be handled quite well with what I ended up with.
Many thanks to all and sundry who replied, all information was gratefully received.
I whipped up a bit of suitably sized timber from a bed post, scrounged from a nature strip find. It's pine but is what I decided to cut my first threads on to get an idea of how well or not so well things would work. To be honest, I am more than impressed with what I received. To put things into perspective, the pilot hole is 12mm.
Mick.
