Many thanks for the offer Eric, that is most kind of you.

If ever I need anything, I will let you know.

I have had massive shipments sent from the US for the bike, and they came to less than what Smallparts charged me for a little bag, and faster delivery as well.

But I have to admit, I could spend a fortune in Smallparts pages, they have almost everything I have difficulty finding anywhere else, all in one place.

Just a tiny post this time, as I have reached a stage where the job has to stop for a few hours.

I am now doing the rebuild on the top end.
Part of this requires putting the engine back to how it should have been made, that is with studs, washers and nuts instead of screws on the steam chest covers. So that is what this post is about.

Not having any correct diameter material to cut the studding myself (which I would normally do), I actually bought some steel 8BA studding ready made. I cut 8 lengths at about 25mm (1") long. The length at this time isn't critical as it will be cut to exact length after the parts are all bolted together. After chopping up, both ends of each stud was ground up so that a nut screwed nicely onto it. This studding is about 2mm (1/16"+) diameter.

Using two nuts locked onto a piece of studding, the ends were dipped in some threadlock and then screwed all the way home in the holes in the main block.
After they were all in, the steam covers were pushed most of the way to the end. But not all the way, there will be some threadlock displaced during the cure, and I don't want the plates being bonded to the block. The reason for the plate being there is to keep all the studs in line while the threadlock does it's job.
The first job to do next time will be to clean off the unwanted threadlock that has appeared on the surface.

Tomorrow, if all goes well, should see most jobs done, then I can get onto retiming the engine. Having these studs in will really help, as it is easy to assemble everything accurately without the steam covers on, that, coupled with leaving the cylinder caps off, will make the job a lot easier.

Have you got the paint yet ? Brunswick Green ( dark I think) I got some from Phoinix paints supposed to take heat.

No paint required Peter, this is just a mechanical refurb and repair.

To have me strip it down and repaint it would cost the customer a lot of readies. It is easier for him to carry out the touch ups required if he wants to.

Every time you tease us with this engine I can't help but to find it fascinating.

Thank you for all the "how to's". I look forward to every one of them :thumbup:
