Frame Brace

we have a lot in common, have had 8 operations on my right foot since 1976, hit and run accident on my SF2, 6 in 76/77, next in 97 and last operation couple of years ago in 2020
and I'm just a solitary bloke in a hot garage trying to fix the odd engine or two

Ow, ow, ow.. I am just a beginner - you have my sympathies. This is turning into a body parts posting..

Are those horizontal bars for mounting or part of the bracing (two holes in each)? Seeing my welder Monday now.

Many years ago, I was coming back through France and I started to get a wobble from the front end. At Calais I took a look and both frame tubes had cracked all the way round!
Long story short, my mate who worked at British Airways took the frame into the hangers at Heathrow and got the frame welded and some subtle gussets made from aircraft steel (I can't remember the grade but it would have been a lot better than the frame!) welded in. The difference was astonishing, gone was the Laverda triple weave, the bike has always steered extremely well since then.
Moral, if you find an original that has not yet cracked, get a well fitting and subtle gusset welded in, it will make all the difference.

Fantastic story and confirms my welding plan. I think I've found a recommended (classic motorsport) welder locally, off there Monday. Templates using the Red example made up. As I said, I stopped using Autocad, the cardboard is out!
 
The triples always had the horizontal bars,early non oil cooler bikes only have the top one which anchors the steering stop to the frame,later ones had the lower bar to take the lower mount for the oil cooler. Hope that’s helpful

Oggi nobs mounting bar looks a bit high in the frame Red.

Hopefully it split apart when stationary. Can't imagine the mayhem if mobile.

Thanks Tom, I realise that having had Laverdas for 30+ years I still know nothing!

The bit I was referring to is in the pic below - if my posting works (do I need to use Flickr?). further research looks like it's a coil mount. Next job - new ignition system, think I've found an Ignatech guy locally.

Thanks again for help, and especally patience, I'm fairly useless at the best of times.

Edit: a Redax/ Ignitech/ Sachse person....

Yes coil mount positions and the 2 holes further back are for fairing mount brackets 👍
