So... castings are out for Vapor Blasting... Hardware is out for Cad Plating... Have a round of parts inbound... Tank and Fenders are going out for paint next week. While the plating and vapor blasting is out getting done I'm going to work on my Honda's top end and see if I can get that thing working again and sort out my oil issue (No oil getting to the left side of the motor...

Nate,

where did you find to do that vapor blasting? I have a few castings that need to go for vapor blast.

BTW This bike officially just turned 47 years old. (which i will also do in a few weeks.) Serial # puts it as a late June '69 bike which leaves only another month of manufacture before the 1970 model rolled out in August.

Hoping that with this rebuild she'll see another 47.
 
Last cover is done... Couple of gouges still by the kicker hole... But the amount of material to remove to get those out might make the cap hole shallow. So I'll leave those alone since the kicker will cover it and probably gouge it again eventually.

Connecting rods all polished up and ready to re-install on the crank. I was pleased to discover that the crank journals were 100% spec (1.624")

I got the cylinder media blasted and ready to powder coat. I used the highest strength paint remover. I could find and nothing would strip off that 47 year old factory paint... What the hell? Took forever to blast it off too... I've blasted off powder that was easier... Any hoo... I'll get it powdered up before the machinist so that it doesn't flash rust on me.

So I went through my containers of engine parts and cleaned up as much as I could the bolts and nuts and stuff that I neglected to include in my batch that went off for plating. I'll probably run out to Fastenal and see if I can get some new replacements for a few things. I don't need much, a philister screws for the Tappet retainers, and a few nuts, and some 1/4" seat pan bolts that Neglected to include. There was enough oil and grease caked on them that mostly they weren't in too bad of shape. The '69 is mostly UNF threads thankfully... I can actually get that stuff local, the CEI/Whitworth stuff is unobtainium here.

My intake valves look pretty decent, but my exhaust valves are pretty pitted. they'd probably still seal okay after a good lapping, But I may try to wee if my buddies have an extra pair... I need valve guides, I can get a whole set of valves and guides for the same money as a pair of exhaust valves and guides though.
 
New valves and guides and the remaining ignition parts arrived today. My parts came back from vapor blasting yesterday. I can finally take my head and cylinder off to the machinist for machine work on Monday.

Finished cleaning out the sludge trap today... What a shitty task... nastiest thing I've ever had to clean on a bike...

Did you pull the flywheel bolt, then pull out the tube to fully clean the trap? If you didn't, the trap is NOT fully clean.

Even worse, more debris may now be at risk of getting to the bearings (it's located BETWEEN the tube and the crank walls)

Yep, Pulled the tube and cleaned it nicely, filled the trap with some kerosene and made sure the journal holes were free and clear. 8)
 
Then by all means, proceed to assembly!

...Although, technically, the VERY FIRST STEP in assembly is slipping the sludge tube back in the crank!

Then technically I have begun assembly! Cause that is complete.
