At last I have been able to get back into the workshop and do some work on my projects. The cylinder head went relatively well even though the one here is the second attempt. The reason for the second attempt was due to the shape of the boring tool not allowing me to get enough thread inside the cylinder head. Once I worked out the problem it was just a matter of 'adjusting' the shape of the tool. |
The procedure for making the cylinder head was well described by Ron Chernich. After chucking the 1" dia bar it was centre drilled and opened out until a 1/2" end mill was used to give a flat bottomed hole. The next task was to cut the internal threads to match the cylinder liner. Ron suggests that the hole it tapped to suit the compression screw whilst still centered in the chuck. I was a little aprehensive about the fins but in fact when it came to it I found the task most enjoyable. Whether I would have felt that way if I did not have DRO's (digital readouts) I am not so sure. In the end it all went bye quite quickly. The next two tasks will be the con rod and the crankshaft.... both of which I am looking forward too. However the cylinder head is now complete. |
