Resurecting my Webster IC project

[stevehuckss396]

Hello Chuck!

Try drill rod / silver steel for your rods. Its good and hard but still machinable. It polishes up nice so the stems can be made to a great fit.

I've made some progress on my Webster. I've made the valve blocks, the valve cages . the cam shaft (though greatly simplified) and the oiler cups for the crank bushes and cylinder.
In looking at the plans for the next part to make, I looked over the crank pin grease cup. I realize the purpose of the grease cup, and would prefer to use it instead of an oil cup so as to not fling oil everywhere when the engine runs. I don't see the grease cup on the assembly drawings. does anyone that has built the Webster have any build photos on their implementation of the grease cup? I don't think I'm at the skill level to cut a 5/16 x 40 internal thread...

You don't really need that grease cup. A squirt of oil from an oil can will give that area enough lubrication for a one hour run.

Brian is correct. A little shot of oil will buy you a while. More than likely more than an hour. If you are uncomfortable with that you can drill the cups for the crankshaft and then just use a large center drill to make a countersink in the aluminum. Couple drops of oil in the counter sink will do the same thing as the cup.
