Report on our meeting 02-03-2023. A demonstration by Alec Mutch.
Our meeting this week on Thursday 2nd March 2023 was a demonstration by Alec Mutch, his project was to make a small natural edged vase/cup from a newly felled log working it in end grain, the wood would be very wet and the use of a light source would be part of the demonstration.
The method used required moving away from the conventional method of turning where end grain working is usually done from the centre out. On this occasion it would be worked from the edge of the log to the centre using a spindle gouge for the most part. The other important part about this turning was the cup shape needed to be done before the final shape of the cup was formed on the outside, the reason for this was that a light source would be used, placed inside the cup and using a LED lamp to light up the inside. The green wood being very wet allowed the light to glow through the wood as the side walls of the cup got thinner. For this type of turning to be a success the turning needed to be down to about 2mm in thickness for the whole turning, by watching the light glowing through the wood it’s possible to achieve a fairly constant thickness just by following the colours glowing through, it will start out fairly muted colours of pale pink but as you pare back the wood on the outside the colour will change to bright red, if you follow the colour you should end up with a side wall and base of even thickness. There is little to be gained by sanding at this point, don’t cut it free from the piece being held in the chuck, put the whole thing into a Microwave oven and give it 1 minute on defrost then leave to stand for 5 minutes, repeat probably 3 times, after this process put the item back on the lathe and sand seal and polish or if you prefer do an oil finish then cut it free, hand sand the base.
Here are a couple of supplementary pictures of the process.
Most of the pictures taken by Nick Simpson.
The turnout was good, and the club members did participate in many questions.
Our next meeting is on the 16th March 2023, it’s a SHOWTIME meeting, bring and show the items you have made recently or over the years, you are allowed more than one item to show, infact, more the merrier.
