There is a piece missing from one of our lathes. It looks like this, and has come off the tailstock. The square plate may be round, and it is about 6 inches by 3. It is the bit that sometimes falls off when you slide the tailstock off the end of the lathe bed, and I suspect that this is what happened. Someone has probably found it, picked it up and put it somewhere safe. Quite a few of us have looked and cant find it. If you are the person who put it somewhere safe, please let us know, so that we can put it back. If you absent mindedly put it in your pocket, this is why your jeans are so uncomfortable, heavy, and why you lean to the one side. The lathe can not be used for spindle turning until the part is replaced.
We still need someone to look after the show on Monday 24 August, morning or afternoon or both. If you can help, please email Phil H, email phil.howard50@btinternet.com or ‘phone 01556 610998.
We sold 11 items today, including two that I’d just brought in !
The exhibition at the Tolbooth is going well, with a good number of items sold. Tolbooth management has suggested that restocking would be a good idea. If you have any more quality items that you would like to sell, please bring them along to the Tolbooth in KBT. If you can’t manage to get there, why not take them to Turning Tuesday, in the hope that someone else will be heading that way?
Remember that you will only get about 60% of the sale price, so price them accordingly.
Extra items must not be placed for sale until they are numbered, priced, and entered in both catalogues. One catalogue is upstairs, with the exhibition, and the other, downstairs at the desk.
In order to turn you need to be able to hold your work on the lathe.
The most straight forward way is to use a chuck and Phil told us all about shop bought chucks the other month.
Work holding is one of the 3 main elements of woodturning:
1 Sharpening
Turning techniques
Work holding
Work holding as it applies to us is the way we safely and accurately position the work piece on the lathe so that we can turn it.
When we prepare to turn anything we should think about the entire process so that we know how we are going to hold the piece for each operation.
Whether it be reverse chucking a bowl to finish the bottom or rechecking a box lid to finish the inside.
If we don’t prepare ourselves then we might find we have no way to hols the piece in order to finish it!!!
There are many ways of holding our work pieces and it’s well worth learning a few trick of the trade.
Most work holding fall into three categories: the 3 S’s
Squeezing, Sticking, Screwing, Sucking
(not my alliteration but Kurt Hertzog in the Woodturning Mag)
So Squeezing, Sticking, Screwing and Sucking
The 1st S – SQUEEZING
Between Centres: Arguably the most secure of all work holding methods.
You have the headstock providing the power and the tailstock providing the squeeze, keeping the piece connected to the drive.
Marking Centres
2 & 4 Spur drives – give a good hold – problems: can lead to splits and also can tear the fibres and spin – particularly on wet wood.
Morse taper – Cleaning
Self ejecting tailstock
Other drives
Steb Centres – Spring loaded point so you can disengage the teeth without removing the point.
Given better grip than the spur drive and will not split the wood.
If you were at the Joe Laird demo the other week you would have seen Joe jamming the wood between the chuck and the tail stock – yes it works but not the safest method!
As well as Squeezing between centres we also squeeze by holding on a chuck of some description.
First of all there are the home made chucks
Wood Jaws – use of Wood plates
Cole Jaws
Longworth chuck – www.woodworkersguide.com
Off Centre Chuck
Doughnut Chuck
Mandrels
Pin Chuck
Collet Chuck
Jacobs Cuck
Jam Chuck – one of the most useful methods of work holding particularly if you are making boxes –
The 2nd S – SCREWING
Faceplates – on Chuck – direct onto spindle
Natural Edge Bowls – Seating with use of Forstner bits
Screw Chuck – bought – one way, – Axminster!!
Home made !! – ok for small items (draw handles
Use of Spacers
Eccentric Chuck
The 3rd S – Sticking
Hot melt glue Glue blocks ( not end grain) Sticky Chuck
There are still a few places on the Better Bowls workshop on Saturday 25th July, so if you can make a bowl, no matter how rough, then come along next Saturday, and we will have a look at improving what we do. Bring along some of your bowls, the good ones, and the ones which you can claim someone else made! and we will see how to rescue the less elegant ones. I will be there at 10am and we will close the workshop at about 5, but feel free to come and go – the early ones get the best lathes! bring your own wood, or the club has some we can sell you, or you can reshape something you bring.
The notes from the Club meeting about Abrasives on Tuesday 9 June are now available on the Club web site. From the home page, click Library, then scroll down to the end of the Presentations section and click on Abrasives.
