An entertaining and informative demonstartion by two club members

Barry Clay and Colin Ratcliffe

Colin Ratcliffe
A Crocket mallet
The Head.
Start with an "Oak" blank between centres pre drilled with a hole (22mm) for the shaft.
Colin explained about his sizing jig.
Turn the blank to around 70mm. Mark the length then turn a spigot to each end. Set callipers 1mm over size and turn down to match, repeat to other end.
Re-fit this time in a spigot, mark length of S Steel ring and label a as they are very slightly different.  Start parting off with tailstock in place, then remove and continue to Carefully part off. Turn some small rings in the end and clean up. Check the ring "a"  adjust as necessary. Repeat the process for the other end with ring "b" until both are a snug fit. Hammer on the rings.
The shaft.
A broom handle, purchased from a farm supply merchant, or good hardware shop. Mount the handle in a chuck at one end then mark 80mm to go through the head and turn down to suit the 22mm hole in the mallet head. Give a bit of shape to the handle with the help of Syd Godfrey’s home made centre steady. True up the middle of the broom shaft before fitting the steady. Now position the steady and turn the shape to the shaft. Put a little grip to the handle, a series of small Vees. These can be burnt in with piano wire if desired. Just firmly tap the shaft into the head. For extra security and also decoration a small V cut can be made in the end of the shaft to take a wedge, in a contrasting wood looks great.

A load of balls.
A thorough explaination was given by Barry. Starting with a cylinder to suit your guide in this case 75mm
Form a spigot to fit your chuck. Mount in the chuck and square off the tailstock end. Mark on the length of the ball and centre line from the template. Turn a spigot to each side of the ball. Remove the excess wood near the chuck to give space to form the sphere. Use the template to mark where to turn off 45 deg angles. To provide a guide position the toolrest at 45 deg to the spindle with the aid off a template. Turn 45 deg to line whilst following the rest. Repeat for the other side. Mark the centre of the 45 deg bevel. Assemble the ball turning device. Barry now explained  the construction and making of the jig and its setup. Fine adjustment may be necessary with a hammer  to ensure it cuts exactly on centre. Gradually take small cuts to form the first part of the ball. Get as tight to the spigots as you can. A quick sand then saw off the spigots leaving a little left to form a perfect ball. Fit 2 homeade cup chucks to head and tail stocks. Position the ball between cup chucks. Carefully remove the spigots, then sand. Finished, a perfect ball, we hope.
