Strange , we have never had a joint failure in 7 years . Both the original 20/20 e-trikes are still intact .

The clue is probably in the text ?Old age Paul
l can only look at pictures .
The "bent " boom l felt had some inherent problems. With the straight boom it could be easier to add a gusset either side of the top side of the main boom .
Your welds look a little on the cold side - not enough fusion going on. Maybe a few more amps, or slow wire feed down a tad?Hi All,
I spent today fabricating some gussets and mounting them. Made out of 3mm plate, I have welding then fore of the boom only. The angles are extremely difficult to get the MIG gun head in place and still be able to see what you are doing. That and it has been a while since I did and welding, so a little out of practice.
First repaired the tear.
Then added the gussets.
Welded both side of the gussets.
Do you think I need some aft of the boom or do we think this would suffice ?
The problem with doing one aft would mean it will foul the chain idler, so that would have to be moved. That and I'm sure the gun angle would mean I would only be able to weld the outside of the aft gussets.
Thanks
