I've just ordered one of these

Anyone got one??

No, but i do know that method of mounting a wooden block to a lathe can be very secure. We used to do metal spinning and wooden chucks were often used for small run stuff (chucks are like the outside form of wooden bowl but not hollowed). A lot of force is applied spinning steel or aluminium sheet over a chuck and if the mahogany failed it was rarely at the thread (which I believe was 1" whitworth).

Not much good if you have an odd nose thread like 1.25 by 12tpi (Myford)

But most nose threads are actually one of the "standards" like BSF, UNF or coarse metric, so it may be possible to buy suitable metal taper taps from specialist tool suppliers. Or from car boots if you live in areas where heavy engineering has died.

They look like a damn useful idea Lurker!! Let us know how you get on!!

Richard,

If you have any 1" x 8 tpi heads on your lathes you are welcome to borrow it
Once I've had a play :twisted:

Any idea what a lathe 1" x 8 tpi " standard Thread size" is??

Reason I ask is I have a number of half inch thick 6" O/D aluminium disks I fancy making into face plates

I'm got a list somewhere of most of the different makes' threads, but for what it's worth, 1" by 8tpi is 1" UNC. (Unified Normal Coarse), for which stnadard taps are available.

****,

The Thread cutter arrived yesterday and as you say -thats exactly what it is!

However its one of those "I wish I'd thought of that before" moments.

I had a quick go last evening.
22mm spade bit for a hole and then cut the thread and away you go- took less than a minute.
I ran up a small cup chuck ( from square stock) in a few minutes.
I made a mistake of drilling the hole too deep and as I turned the wood it jammed on the thread collar and took a bit of shifting. other wise its great.
A mistake that will not be repeated.

The thing has got me buzzing with ideas
Its much easier than mucking around with a face plate so first phase of turning a bowl will be quicker.
I can now knock out as many jam chucks, stropping wheels, sanding discs etc etc as I want.
No more b*ggering around with screwing wood to a face plate and it being off centre when I re-mount.
More secure than a centre drive with big spindle jobs
Also you can "get behind" the wood, something that's not possible with a plate.

I'm dead chuffed :lol: :lol: :lol:

:-k :-k Hmmmmm, now you've got me thinking about it.... how much did you say it cost you???

Would it be worth bringing it along to the "BASH" Lurker to have a gander at :?:

Hi Lurker,

22mm spade bit for a hole and then cut the thread and away you go- took less than a minute.

Any chance you can tell us how you cut the thread. What I mean is did you use the thread cutter in a drill, or by hand, or on the lathe, or something else? Sorry if I'm just being a bit daft.

I'm seriously tempted myself, although I see the M33 ones are a bit more pricey.

Cheers,

Dod

With VAT & Delivery it was £18.
Ordered one day at lunch time - delivered by Royal mail next day :lol: :lol:

I just ran it into the wood using an adjustable spanner on the flats, just run in by hand. It doesn't matter if its square or anything because you square everything up when you turn the shape.

My guess is its actually a cheap grade "metal" tap; it cuts very easily. In itself its nothing special - its more the "idea".

I've made a few more "faceplates" out of MDF at the weekend Obviously I expect these to strip the thread but am experimenting anyway. At worst I'll have to turn a small block of hardwood and screw the MFD plate to that.
With unlimited face plates of any size I want, I can now have several jobs on the go at once.

Will bring to the bash with a few plates & chucks - by then I might have a bit of experience with it.

Hi Guys,

I have used this very successfully on my Record lathe. I bought a relatively cheap metal tap and the correct tapping size drill. It works well, I used some scrap beech blocks and now have a variety of wood chucks. The main thing to remember is to allow the correct clearance for the shoulder so the thread will always screw up square. As has been said it is really easy to create sanding disks etc that run true every time.

Happy turning,

Mike C
