25 Oct 2022 – Colwin Way Demo
COLWIN WAY DEMO
This month we welcomed back to our virtual workshop Colin Way joining us online from his actual workshop in Lyme Regis. Colwin is a professional woodturner who also teaches the craft, demonstrates it and also manages to fit in ambassadorial work both here and abroad for Axminster tools.
Colwin started the evening with what he described as a warm up piece. He mounted a joinery grade piece of softwood between centres and told us that this would be transformed into a table leg almost exclusively by the use of a skew chisel. At this point he showed us the range of skew chisels that he uses all having a 25 degree bevel angle and a skew angle of 15 degrees. The turning then began and in what seemed a very short time the pommel for the top of the leg had taken shape along with beads, coves and other refinements that formed the finished article. As he was turning Colwin demonstrated the correct use of the chisel and what happens when the rules aren’t followed by deliberately incurring catches. A masterclass of how to use the skew.
That done the main event followed, this time a Christmas carousel, very popular in German Christmas celebrations and therefore based on a German design. This project is made up of many different elements and requires general woodworking skills as well as turning. The carousel has four tea lights that sit outside of a rotating centrepiece at the top of which are twelve impellers. These are angled to catch the rising hot air generated by the tea lights and rotation occurs. Colwin stressed that while this project may look complicated it should be within the skill set of all turners and throughout, he also explained the various pieces of equipment he uses to complete the task.
The first was a sanding table made from a piece of timber and mounted on a shaft that fitted into the banjo which allowed the small pieces that formed the feet to be presented to a homemade sanding disc held on a faceplate.
The tealight holders had been predrilled with a 42mm forstner bit with a 6mm hole in the bottom to allow then to be mounted onto the feet. Each one was then held on a jam chuck for shaping. Next came the base plate which required some holes to be accurately drilled on both sides including one in the middle that would take the bearing for the spindle. That was then held by the tailstock engaging it onto a jam chuck and the edge was shaped. A baseplate for the central column was similarly produced.
The central column itself was formed from a piece of oak through which a 3mm hole had been very carefully drilled so as to ensure the hole ran true through the length of the column. Once complete the metal spindle was pushed through the hole and the fit onto the bearing checked. Next came the two outer columns that support the arch, the object here was to produce two identical columns although Colwin stressed that nearly identical is usually good enough!
The central hub that holds the impellers required the use of another aid, again a piece of wood that fitted into the banjo with a hole drilled through. The jig was set in the tool rest so that a drill bit could pass through it and engage onto the hub exactly onto a centre line that had been drawn onto it. This coupled with the use of the lathe’s indexing system facilitated the drilling of 12 holes in exactly the correct place. The impeller holders had been produced by cutting slots into them to hold the blades and the ends turned to the correct diameter to fit into the holes just drilled. The wood for the blades themselves was prepared on a planer/thicknesser, cut into rectangles and then sanded to shape using the sanding table and disc mounted on the lathe. The final piece was the arch which was marked onto a piece of wood using a template and cut out. This can be done by using a bandsaw or scroll saw. All the elements being made assembly is quite straightforward.
Having done all that Colwin was onto his next project, a small Christmas tree using a piece of Lime. Using only a skew, Colwin turned the wood into a basic Christmas tree shape and then made a series of cuts which left the ends of the cut fibres standing up all with a feathery appearance. Once painted using an air brush the tree would be complete. Excluding the painting the job took six minutes.
Next! We were then given the choice of seeing either a small vase or a pendant being turned. The vase won the vote, so Colwin declared he would not use a chuck but make it entirely between centres and only resort to a jam chuck for the final operations. It would be made from a piece of Thuya Burr, an exotic hard wood that has a high oil content.
As promised the wood was mounted between centres and the outside shaped. Sanding followed but because of the oil content Colwin used wax on his abrasive in order to stop it clogging up. Once sanded a coat of cellulose sanding sealer was applied. He then proceeded to make a jam chuck which enabled him to hold the vase for the final shaping and cleaning up of the bottom. The bottom sorted It was reversed in the chuck so that a hole could be drilled down the centre and the inside of the neck blended into the hole. All that was left was polishing and this was achieved on the buffing wheel which resulted in a high gloss wax finish.
In a little under three hours we had seen the production of a chair leg, a carousel, a Christmas tree and a vase. At no time did the demonstration feel rushed and throughout Colwin gave tips and advice. We thank both Colwin and his wife Vicky, who did a splendid job of managing the cameras, for a memorable evening.
Thank you Alan Selden for another great write up of what I think will go down as one of the best demo’s we have seen for a long time.

This Saturday, 29 Oct 2022 from 10am to midday, Mick will be opening up the Club Shop for you to stock up on your woodturning supplies. A new large stock of timber has just gone on display. If you can, please come along to make it worth the effort of opening up.
