peatol/taig parts

hi

just bought my first ever lathe,at the moment cleaning all the treacle off it etc.

Question is there a 3/4 jaw chuck that i can buy from that will go straight onto it,or does somebody know the thread size so i can go search for one.(one of many parts i think i will be needing )

thanks

phil

The thread form for a Peatol/Taig spindle nose is 3/4" x 16 tpi (60 degree inclusive thread angle), used to be known as UNF. Not sure what they call it now. I bought my Peatol back in 1985 with full set of accessories and spares.

At the moment, I can't find any distributors of this manufacturer's accessories in UK. The main one that shows up online in a search is Mr Morrison's, but suspect is now dormant?. Regretful if that is the case, as I purchased mine from him, and I would like some of the newer range of options. Suspect I will have to look to US and ship over.

A quick search using the 3/4" size does throw up a few alternatives for chucks in UK . Good luck

I have no idea if the Peatol UK distributor (Peatol Machine Tools) is still working. However I have successfully bought parts and accessories (recently) direct from Taig in the US. They are very helpful and very responsive to E-mail queries.

Shipping gets expensive, and you are stuck with the dreaded VAT and duty, but it does work, and the parts and accessories are surprisingly cheap but high quality. Parts & Accessories Archives - TAIG Tools

They do a three jaw self centring chuck with machinable jaws, and four jaw independent and self centring ones.

Arc do Peatol (3/4 x 16 tpi UNF) backplates that will allow you to put their small chucks on as an alternative.

Sherline chucks have the same UNF thread, and can be bought from MillHill supplies in the UK, but they need a seating register between the chuck and the spindle face (you can find the details of making one online) .

One last thing - do check that the spindle nose thread is actually 3/4 x 16 UNF. Taig do a version of the spindle that takes ER16 collets ( which is what I have) and that has an M22 x 1.5 thread. If it's a fairly old unit it will most likely be the UNF one. But if you have got an ER one , buy a set of ER16 collets and use them. I do have 3 & 4 jaw chucks, but they only appear when turning something bigger than 10mm otherwise the ER collets are far nicer to use.

Searching for 'taig spindle nose' would have provided you with an answer. I believe the 3/4"-16 spindle nose is also used by the Sherline machines. You could search 'sherline spindle nose' to confirm.

It is also used by a few woodworking machines - inter alia the Clarke range by Machine Mart.

Sherline make a range of excellent chucks with 3/4 x 16 UNF thread. Can be bought direct from Millhill Supplies, the UK agent for Sherline.

This is my problem,I don't know how to check a thread on machine.it measure 19 across and if I put a thread gauge in the thread it is 1,5 so feel stupid trying to work it out thxs

Thxs for replying to my list all

3/4 x 16 UNF has major diameter of 19.05mm and 1.587mm pitch. Sounds like you have a standard UNF spindle.

Thank you very much ,also I need a new micrometer lol,mine says 18.92, now I can look for bits for it much appreciated

Richard -

" The thread form for a Peatol/Taig spindle nose is 3/4" x 16 tpi (60 degree inclusive thread angle), used to be known as UNF Not sure what they call it now. "

Errr, UNF! The thread is still known as UNF.

If you still need make a back-plate or other fittings, taps and dies for the American UN range are readily available. Tracy Tools, for one, lists them.

Screw-cutting the threads would be facilitated too, by the 60º being also that for standard metric threads.

'

(UNF and UNC became common in the UK with American car manufacturers taking over ours, and by the ranges being for a time at least, the main system for NATO-standard military equipment.)

It is quite instructive to read the comments in this document:

http://practicalmaintenance.net/wp-content/uploads/Fundamentals-of-Threaded-Fasteners.pdf

starting page 13. It says that UNC and UNF were standardised in 1948 (before that, it was ANC and ANF) and by 1965 the British Standards Institution were requesting that they be considered second choice threads after ISO metric. So as a thread standard, it has had a surprisingly short life in this country at least.

Peatol.com was still trading in late 2019 when I bought a milling slide and vice. I also have two backplates from Arc but both wore out after only a few uses holding end mills in the collet chuck. I should try Mr Morrison at Peatol. I believe he only takes orders by phone but the 3 jaw chuck I got with my lathe has given excellent service.

The location of 19 Knightlow Road is easily found on Google Earth, and visible on its Street View as a detached suburban house.

non-contact in these difficult times could have many explanations ... I hope all is well

Phil, not sure what happened to your post of the 12th which I got as an alert.

"Me again,can I ask for a bit of help,I thank you all for the help. I received last time so
going to try my luck once more.

3/4 x 16 UNF is the size you helped me with,so I thought ni would look for a Colette nut
or maybe it is called a retainer nut.tried contacting Peatol UK,no reply so tried America
taig no reply there,so been looking on eba and Amaz (don't know if allowed to say
names in full )can't see what I need.found a kit that you put a holder in a chuck to use,but
thought it might be not so good and at 57 pounds seemed bit over top.i gave emailed
Axminster tool ,to see if they can help.tried to do as much foot work as I can,but unf
confuses me."

What you need are a Taig 1042 collet nut and probably a set of 1040 collets.

You searched for 1040 collet - TAIG Tools

I have always found Taig responsive to E-mails ( it might take them a couple of days to get back to you, and they are seven hours behind us in time terms.

hi,me and computers are not getting on this week lol.

i spoke to taig tools last week they asked what i needed so gave them a list,but that was it,havnt heard nothing since.same thing with peatol they asked for a list and nothing since.so what i thought was try and track a collet nut in uk but to no avail

thanks

A further option is to look at Axminster's Junior woodturning chuck. It is an ER20 chuck and can be bought with a 3/4-16 backplate.

The native Taig collets are very limited in the diameter they can hold, but do offer a very short projection from the spindle. ER20 will hold up to 13mm but does stick out a bit.

There are at least two other ER systems that fit a 3/4-16 spindle, the SCT from Chronos (but it looks to be discontinued) and the Beall (but this does not seem to be available in UK).

See:

https://www.quality-woodworking-tools.com/product/sct-collet-set-system-for-wood-lathe-3-4-x-16-tpi/

https://bealltool.com/products/turning/colletchuck.php

A collet nut on its own will not help. The Taig collets are a proprietary size so even with a collet nut you will not be able to do anything unless you have a set of collets.

One reason I opted for the ER16 headstock when I bought my Taig.

I feel sure you will hear back from Taig - they do take a few days to respond sometimes, and things are a bit fraught in deepest America at the moment!!

Thanks all again,I'm trying to run before I can walk.peter regarding the collet nut,I took onboard your first reply about using collets,so I thought get one of them instead of a chuck.i am going to crawl now and get a chuck,also collets but let's get it up and running first.

Regards to taig tools,Im like a child in a sweet shop,and want to buy vloadsvofvgiidies this was meant to say loads of goodies.roll on Friday,when I can put my laptop back together and use that thanks all for help
