You are obviously using the wrong milk crate.
Or, just use some ply to get the cradle off the crate.

I used a TrailTech digital speedo/tach on a Honda FT500 and I liked it very much. It was easy to read, easy to set up and worked flawlsly. It just looked a bit funkey. It would be nice if they made something in a vintace round style since I need a whole Smiths kit for my Triumph project. I hate to shell out the money for something so prone to breakage.

Also I’m having a huge gap with my rear isolating. Anyone encounter this either??
That's an 850 Mk3 battery tray so the battery strap fastenings are different and opposite to those of a '69 central oil tank model (that has RH battery access) and there are no pins to locate the side panels (left and right-hand).

practical frame straightening
Has anyone successfully straightened the frame on their Commando ? I'm not looking for the world's straightest Commando, but I would like my bike to be a little straighter. Obviously the frames can be adjusted. I think the upset occured when I dropped the bike on the right side. Now the...

I was told that a stock brazing setup but the paint is just worn off.
I had rotated and removed and adjusted and tried everything that’s a photo of it resting because getting that to all sir just right for a photo would be super tough. Trust me I tried everything. I ended up pinning it from the front and rotating the cradle and engine together that way, but it’s really pulling hard on the front isolastics, to the point that it’s shoving on the inner rubber

We have three types of battery boxes and I was monkeying with what looked best. But I had no way to identify which was which. This helps a lot

However, it would be welded, not brazed and looks like two diameters of tubing [Edit: The step in the diameter appears to be normal.]
You need to consider the possibilty of a bent frame. There are some checking dimensions in the workshop manual, so I suggest you compare these dimensions before charging a frame repair shop.

Alright, Checked the frame and checking the transmission cradle dimensions. still in progress. i have two cradles. one of them is brazed and one is welded, they both have the "double" tube look to them. and both match each others dimensions. was it ever stock to braze the weld in Norton?
Picked up a 850 Commando Engine with the RH4 head. It's at the machine shop and head isn't cracked getting 2 thou over guides put in and helicoil the holes, new springs. cylinders being bored to 40 over. Crankcase is in good condition. picked it up from Zener. going to split them anyway and do a full inspection.
Everything is coming along nicely, but it's taking a long time due to financial constraints. still have two options for the front end. stock or a 2008 bonneville front end if the guy is willing to sell it.

RH4 is typically off of a Mk3 - are the cases mk3 then? If so they will have four primary mounting screw holes in the LH case around the crank. The primary is completely different, as it is estart and LH shift and wont bolt up to a RH shift primary.
850 pre mk3 cases only have three mounting screw holes, which should mount up to a 69 just fine.
Note that the RH4 also has 32mm intake ports vs 30mm ports on a RH10, so make sure you get the correct intake manifolds.

Not that I'm aware of especially how it looks in your picture so more likely a repair in my opinion.
850 Mk1 also had the RH4 cylinder head (RH10 on Mk2/2A).

Yes, but wasn't that only 7300 units or so?
Significantly more than that for the mk3 tho right? Hence the comment/ question.

About 10,000-or-so Mk3s but I still wouldn't want to bet my house on it being a Mk3 engine.

If all the serial numbers were used then it could have been as many as 11,500 Mk3s.
Unlikely, however, that many of the last 1,500 assembled would have gone to the USA.

I think I remember from the Ken Sprayson book that the first batch of commando frames was built at Reynolds and thus would be bronze fillet brazed then.
Caution not an expert on Norton's but i think that's what I remember from his memoirs.
Kind regards Christian
Ps: sorry just saw the pictures and that looks imho surely like a repair job and nothing like something that would have come from Reynolds that way.

Reynolds built all Commando (and Featherbed) frames until Norton began buying frames from Verlicchi so from '69 - to '72/'73.
The SIF-Bronze welded frames were the Manx Featherbeds (and P11) as they were constructed from Reynolds 531 tubing.
No mention of bronze-welded Commando frames (although it's actually the cradle) in Ken Sprayson's book.
