Thanks for all your support, Lads! :thumbup: It's much appreciated, when the hobby seems to be wading through treacle, and life is getting in the way.......... :( This engine appears to have had two builders, before me. The first has done a really good job of details. The linkage system fit and finish, is first class....... The second builder has botched a few points. The cross pins measure up at around .106"/ 2.7mm....... :scratch: The original displacer shaft has an 1/8" hole........ The gudgeon pin was an 8BA screw, only locating in it's threaded hole. Not touching the other bearing areas....... So, I drilled through at 2.7mm........ And made a 1/8" headed pin, to suit....... I hate to see wobbobly flywheels. This one had most of it's sections eccentric too! I trued both bosses, and the inner rim. Opened up the bore, plugged and re-drilled to 6mm. The eccentric spokes area, I left as is. A balancing feature.......... The wick end of the burner locates in a central hole. Under the hot cap. Leaving the tank end to pendulum from side to side. So, I fitted a 10 x 2mm magnet in it's base........ And one in the oak base........ Underneath the brass base. Made a new knurled filler cap too......... Put on your sunglasses............ After a some time. The revs had climbed much too high for me. I like to see the wheels go around. So, I trimmed the wick back as far as it would go. It runs around 150rpm now........ HAPPY!!! :) Defor. |
