You are doing the right thing.
Frank griffin told me many years ago: never assume anything, control everything!
He was bloody right and it cost me a lot of money until I remembered his words again.
Keep going
Cheers Bernd

Any thoughts on using a lock washer under the E80 that holds the 1/2 time pinion on?
Thinking blue loctite rather than punch locking should be sufficient provided everything is squeaky clean first. The lock washer would be in the mail for a few weeks if things went as per normal.

Starting to look like it might be a product of North Korea.

Now at 14 inch diameter this IS a timing disk! In case you wonder - its attached to the mainshaft on the ESA side and that hose fitting (in td 02) is temporary so I can set up the timed breather.

 

[Cyborg]

Yes... after trying to peer into the timing chest at the breather, it didn't take long to figure out that a hose was a good idea. Works well. Blowing into the hose probably looks a little odd to the uninitiated.

Lock washer B.S.A. (and Triumph?) part .no. 70-3975. cheaper and faster to obtain. May need a lick with a file on the i.d.

haven't tried a lock washer to retain 1/2 time pinion but used Loctite with poor result and punch locking is the way to go in my experience.

I've had reasonably good success with Loctite in most applications. I clean the parts until I'm sure they are absolutely spotless, clean them some more and then I use some plastic pipe cleaner/primer from the local hardware store. Its a mix of acetone and MEK. Takes a bit of searching to find the one with MEK, but it makes a great cleaner. Nothing beats MEK for removing varnish and crud from carbs other than maybe an ultrasonic bath and drill bits. I suppose I could just buy the Loctite primer/cleaner, but I now have a small stockpile of the MEK/acetone.
A look at post #76 in this thread probably explains why it is hit and miss using Loctite for things like spindles etc.
Being slightly paranoid, I'll probably add a punch lock.

Slowly making progress. Timing chest is done. Milling slots for drive chain clearance and making mounting bolts and spacers for the gearbox. Photography isn't my specialty!

 

[Oldhaven]

I have spent the last three days staring at the nether parts of my empty cases with a view just like that trying to decide which of the 10,000 ways to mount a Norton gearbox I will use. Nice to see all these old Comets coming back to life. You have a good attitude. Nice work. As Bill says, all in good fun!

 

[Cyborg]

Glad to hear you are making progress. My plates seem to be working out ok so far. I spent a lot of time trying to keep everything as compact as possible and not stretch out the wheelbase any more than necessary. I'll have to make up a bell rank of sorts to get the exhaust valve lifter to work.... although I think it was Bill who told me that only a pussy would need one to start a Comet.
