Unobtainium
Looks like this is one of the bits made from Unobtainium, a 8 valve cylinder head for the CB450.
A decade ago I did some serious investigations, trying to get get in contact with, what I believe was, the last man standing, that was involved in making this conversion kit. I have to say I came pretty close, but...
Last year I made another attempt approaching from another angle, so to say. Seems like guys that could help are not interested in helping at all. Ignorant is the word.
Anyway, this is what I was searching for.

Cirtic acid
I think it's a very good home remedy for the average Joe's workshop. Not a very strong acid and very easy to get, just 'borrow' from the kitchen.
I have now used it for zink plating, refurbishing of Amal carbs for my Norton and lately a rusty camshaft.
I just had to try it, but because of the New Years party and other things I forgot...
Anyway after a couple of days I removed the camshaft from the acid. And this is how it looked before polishing the surfaces.
I just put one end in the acid, this is how the other end looks like.

Time Capsule
Went to my local parts dealer to buy a couple of spoke sets for my CB125 project.
The guy behind the counter told me that they had opened "the door, you know" and found a camshaft for a CB450.
"The Door" is the door to a room in the cellar that supposedly was shut in the mid 70:s when the room was flooded or at least water damaged, and never opend until late 2011.
Probably why the camshaft was rusty.
The camshaft is a bit interesting since I guess it's the same model (or similar) to those which was used in the Precision Machining 450 in the early 70:s, described in an article in Cycle World on Honda (1968-1971 edition as I remember it)

Nothing much
Mostly grinding and some latheing. Started with the CB125 brake shield, had to add some JB weld (metal glue) in the imperfections from the welding. Hopefully I can finish that tomorrow.
Also I have had a CB500T oil filter part laying in the shop, for a wery long time. Thougt the condition was so bad that I just could not lathe it down, as I usually do...
Made a new bronze bushing. Had it been a CB450 part it most centainly had gone in the trash bin, since I have got several NOS ones ...
After that I thought I could spend some elbow grease on the modified CL77 lower legs that eventually will go on the CR450 project that has been resting for some years.
The lower fork legs has been modified with new fender mounts and new brake mount for a 4ls drum brake. This is what they looked like after welding.
I also made new bushings for the CB125 rear swing. The oringinal ones were so rusted that I had major trouble dismanling the damn thing. Had to soak it in oil for a couple of weeks.
