A very good turn out with many still away on holidays, we had 67 members attend with two new members, Michelle and Amelia plus one visitor. Giving a total of 70 on the night
Lynda kicked off the proceedings with the regular notices, including lots of wood on the stage for sale, free magazines at the rear of the room and Dave Simpson was clearing lots of wood and tools on behalf of a deceased turner, with more to come next month.
She also updated us with the current total for Denis Hilditch’s abseil fundraiser so far a total of £1200, it’s not too late to donate. Details are in the Autumn “Your Turn”
Our guest turner this month was Paul Hannaby who was demonstrating how to make a needle box with a threaded lid. Paul has been turning wood for around 17 years and is based in the Forest of Dean, Gloucestershire. He is a member of the Cotswold Craftsmen and he exhibits at a number of their events in and around the Cotswolds. When Paul started woodturning, there was nowhere near as much information available on the web so a lot of the learning process was through trial and error. Being the sort of person that liked to experiment and push the boundaries of what he was capable of, this didn’t deter him at all.
Paul started with a quick review of thread chasing tools of which he had a wide selection on show, he advised how to prepare these tools before use for example rounding the edges of the square profile on a grinder so that the tool moves more easily on the tool rest. He then started the main demonstration placing a piece of boxwood between centres on the lathe working at approximately 1800 -2000 RPM used a roughing gouge to dress the lid.
He then squared the ends with a parting tool, before dividing the piece into two parts. Paul then fitted the chuck to the lathe and inserted the half that would become the lid with an internal thread. He reduced the lathe speed and using a spindle gouge to hollow cut the interior, then used a square edged scraper made from a round bar to finish off the bore.
Then using a recessing tool, he cut an internal groove in a position where the thread would end for the thread chaser to run off into. Paul then sharpened his thread chasing tool with a diamond “credit card” sharpener, then prior to cutting the thread he used a scrap piece of boxwood to demonstrate a more visible thread cutting. Slowing the lathe down to 350 – 400 RPM he started at a 30-degree angle and allowed the thread to draw the tool, rather than force it along the thread, applying more downforce whilst gradually squaring the tool to the wood and quickly pulling the tool out at the end of each pass so as to avoid running the thread further than required.
Paul’s advice at this point is to “Match your speed to that of the lathe”. As Paul cut the thread he used a toothbrush to apply renaissance wax to the thread, although any finishing medium of your choice would equally work. This not only helps to sharpen the threads point but also improves visibility as you cut. If the thread is too soft Paul recommended to soft drizzle super glue over it and then re-cut the thread. He also suggested for internal thread cutting placing the tool rest further away from the wood than usual.
Following a shortened coffee break, Paul then did the usual critique of the member’s gallery, again there was a great show of very good turning for him to go through. The draw was won by John Holden for his beautifully turned necklace stand, also worth a mention was Mike Haselden’s Monkey Puzzle bowl.
The second half of the demonstration concentrated on the interior of the box. Starting with a spindle gouge Paul hollowed out the centre recess, which would hold the needles. He then reduced the outside diameter to match the inside diameter of the external piece to accommodate the thread, using a parting tool and callipers marked so that the two parts will fit each other. The external thread was then cut onto the raised part of the cylinder, and then tidied up with a thin scraper.
Paul advised “cutting the thread oversize and then reducing down with the scraper and thread chaser until a clean fit is achieved, and also to retain full depth of the teeth.”
Next thing to achieve is grain alignment. The length of the thread can be reduced to 3-4 pitches to achieve this. It is worth remembering at this point that the two parts were originally some 3” apart where they now meet so perfect alignment is not likely.
Paul then finished the box by cutting square coves on the remaining length of the cylinder, these recesses can be used as bobbins to hold threads. He then returned the whole box and lid to the chuck to apply some finishing touches by cutting a “V” cut on the join and one on either side and three circles on the top of the lid. We were then given a quick overview demonstration of the various pitch threads on another piece of scrap boxwood. Following a generous round of applause, the meeting closed with the usual raffle draw. And many left with arms full of wood purchased on the night.
Congratulations to Denis for completing his Abseil down the Spinnaker Tower’ in Portsmouth UK.
You can still make donations to Prostate Cancer UK being a subject close to my heart (well about 13 inches away) via Justgiving.com/Denis-Hilditch.
PS, 10,000 men a year in the UK die from Prostate Cancer, so men get yourself checked out a bit earlier than I did!!
46 members attended this month’s meeting, We also had 4 visitors giving us a total of 50 on the night.
It was the second visit for 2 of the visitors so hopefully they will join us next month.
This year’s HWA Challenge was to make something from Yew
We had 15 entries from 13 turners, as usual with entries they were all of a high standard. You can see all the entries on the website, but here are the first 3 choices of the 48 members who voted
1st Choice, Harry Woollhead’s Tea Set and Tray
A clear and deserved 1st choice from one of our most experienced turners.
Harry had started out with just a Teapot, but was then was persuaded by Mrs W to make a complete set of Cup, saucer, milk jug and sugar bowl, then he needed a tray to put them on. This outstanding entry was a firm favourite from the start of the evening, and topped the voting by a wide margin, although there was a call for disqualification as the sugar cubes were made of Pine not Yew.
2nd choice, Chris Molyneux
Chris produced a beautifully turned round bowl and lid to a highly polished finish. A lovely piece that you just had to pick up and admire.
It was a close run competition for second place, with Chris and Dave both receiving an equal amount of points with Chris coming out on top by virtue of just one more first place vote.
3rd choice Dave Simpson, for a second consecutive year.
This time Dave produced a delicate pierced hollow form housing a tea light, the flame from which could be see through the piercings. A nicely made imaginative item.
Close behind Second and Third place was Mike Haselden with two entries which came in Fourth and Fifth.
Whilst the votes were counted and certificates being done by Lynda, our calligrapher for the evening, Membership Secretary Keith Barnes took to the front of house to deliver a 30 minutes “Electrical Safety” presentation
Keith gave us a potted history of electrical standards since 1947 including the Ring Main Power Circuit, Amp ratings and cable colourings. Circuit breakers and fuses etc. and also warned of the dangers of using the old two and three way adapter plugs, it is far safer to use the trailing gangs with three or more sockets.
This was followed by a Q&A session where Keith dealt with various subjects including PAT testing of turned items for selling such as table lamps
A much more pleasant Monday evening than in recent months weather wise, saw a good turnout of 59 members and 2 new signed up members Carl and Arthur, also two visitors who we hope that will join us very soon.
Our demonstrator for the evening was club stalwart Mike Haselden a very experienced woodworker who has been turning for ten years. The last time Mike demonstrated he kept us waiting until the very last moment to work out what he was turning for us, this time, he told us from the outset that it was to be some off-centre turning and those who had seen his very impressive gallery entry on the night had a very good idea of what it was to be.
Mike started with a large Ash blank which he secured to the lathe between a sanding disk/faceplate and a revolving centre on the tailstock. He then cleaned the edge with a gouge and continued to do the same to the face.
He turned a shallow dovetail recess for the chuck and reversed the blank onto this. Mike Doesn’t like to rely on the narrow area at the top of the dovetail jaws for seating which would have been the case with such a shallow recess so he mounted the blank via a plywood spacing ring to provide a flat facing surface outside the dovetail.
With the added security of support from the tailstock and centre, Mike then cut a bevel of around a quarter of an inch into the outer edge.
The next step was to remove the blank from the chuck and replace it with a specially made 12” plywood jig, which will be used to hold the blank in three different off-centre positions. The jig is very cleverly designed to hold the blank in place by clamping it along the bevel that was cut on the outer edge of the bowl with 4 plywood blocks. The jig also included an additional device to counterbalance the effect of the blank spinning off centre. This was a movable plywood cup that contains removable lead weights that enable Mike to adjust the weight.
So with the mystery now out, we are going to get a three centred bowl. Mike proceeded to mark out three new equally spaced centres, using basic geometry and a pair of compasses. With this done he secured the blank into the jig and proceeded to hollow out the three equally spaced bowl inserts.
Due to the predicted length of the demonstration two hours ten minutes, there was a shorter than normal tea break, while Mike hollowed out the last two bowls. Bob Hope then did a quick critique of the gallery which as usual exhibited what a talented bunch Hampshire Woodturners are, or at least some of us. And then back to the main event.
Mike ensured that the three bowls were as equal as possible by using a 42mm circular template to gauge depth and shape
Due to the fact that the three bowl indents will overlap, the second and third become increasingly more difficult to turn as you are cutting from wood to thin air in the overlapping areas, this said he achieved this with consummate ease.
The bowl was then reversed onto the recess in the base and the outside shape was turned from the headstock side, something not recommended for a novice turner. The final finishing of the base including removal of the chucking recess would be done by a further reversing process which could not be covered in the time available.
Mike finished off his main demo by explaining how he does the contrasting inlays around the edges of the bowl. He introduced us to his homemade manual hand router that is made with an Allen key ground to a point as the cutting bit. He first makes the three (in this case) inlays from a contrasting timber, then the bowl is prepared by painting the surface with “Typex” this forms a good surface for marking out the shape of the inlay to cut out by hand with the “Allen Key” router to a depth of approximately 3mm. once this is done the inlays are secured in place before returning the bowl to the lathe to finish off the top surface to a perfectly smooth finish.
With time fast running out Mike turned his attention to turning spheres on a lathe, ideal for displaying in the three off-centre bowls of his main piece of the evening, something that would equally look good with pieces of turned apples or pears.
Again we were shown another homemade jig that was made with an adjustable plywood stand and a semi-circular metal template. Briefly Mike turned a short piece of wood down to a few mm thicker than the required diameter of the sphere, he then reduced the ends that would be wasted to under 20mm, then using the template as a guide gradually turned down the sides of the sphere, fine tuning by moving the template closer as the cuts allowed, a process similar to using “fingers” when production turning. The bulk of the ball is then sanded on the lathe before removing the ends and the sphere finished by hand.
Following an appreciative round of applause for Mike, we moved very quickly onto the raffle as we had overstepped our 10pm curfew, before all setting off for our usual Ovaltine and bed
