Presume the crank journals set 90 degrees apart on this engine? Do you have a method of achieving this or just by eye?Nick
Tim,For the low block, just shim it up with layers of bacofoil, it might only need one or two. But get it before you have done the Sunday roast in it, less crinkles.If you start to try bringing the others down to match the low one, you just might make it even worse.John
Tim,Really I think you are taking things a little too literally.The oil hole is just that, a place to wack a bit of oil into. It could have been a lot larger, within reason. It was just a way of reminding people that it is a hole and it is there for a reason. When lubing up the engine, you see a hole, what is it for?, you remember that a spot of oil is needed down there occasionally, job done.It is only when you use a calibrated drip feed hole from a small reservoir that you need to worry about things like that.But coming along just fine now, you will soon be ready for the first air trials.Bogs
That sounds to me as if the journals and shafts are not precisely parallel. If you do want more clearance between the webs it might be better/easier to narrow the conrod ends.
Before re-making the spool,
That is the fastest build of one of these engines that I have ever read, and you are did a great job of it.
Those not familiar with this engine, Bogs has written a book to help beginners build an engine. It is a wealth of information. I am not sure where it is hosted now, I am sure if you ask, he will direct you to it. Download it and read it. Even if you don't plan to build it... at least read it.
Hm, sadly I don't see any of the photos in Part 10 and later, only a couple of YouTube videos, and it doesn't look like they made it through your transfer.
