So, after fixing my Trillium's sagging door it became evident that the soft metal used on the bolt for the door handle had worn to the point where the door could be opened with it locked. I read the threads about replacements being unavailable or ridiculously priced (saw a set on ebay with a buy it now of $350US). So I disassembled the lock following the detailed and entertaining instructions provided here....

I had also saw it mentioned that someone had gone to a welder who said the metal was too soft to build it up. So, I took it to a well known trials bike dealer/rider who also happens to be a very talented welder (he repaired the broken frame on my KLX250s). He suggested a different approach, that being, cut the hard steel behind the soft metal and weld a 1/4" spacer. Two hours later (1.5 hrs BS'ing and 20 mins work) it was done all for the cost of $30cdn. I did a little reshaping of the soft metal, reassembled the lockset and was a happy camper when I locked it, pulled and the door stayed closed.
The lesson......when someone says it can't be done, someone else may have ideas to accomplish the same goal.
