	A second sander is used to form the inside of the curve
	Finally, a check to ensure that they fit the pattern correctly. Ruth now needs to repeat for the other end.
	While Ruth was working on the transfer ports, Tony was working on the valve cylinder pattern. On the photo, the extension towards the camera is a pattern makers "print". This will form a recess in the sand mould to support the ends of the valve cylinder core - the sand mould that makes the air space in the cylinder. The pattern needs to be the same shape as the core. First Tony checks the template against the pattern.
	Next Tony assembles the 2 halves of the pattern and uses the template to check for a fit. This shows the surplus material that needs to be removed.
	One half of the pattern has been cleaned up with an oscillating saw ready for an application of filler.
	Filler applied. This will be smoothed off after the Xmas break. Meanwhile Tony can continue working on the Valve cylinder core box ends which he can do in his own workshop. Tony passes on a Merry Christmas to all our readers
