This post is mainly for those who have an antique or prized saw with seemingly irreparable parts which are NLA. This saw doesn't fit those categories, but is a good example to work with. This starter cover comes from a Stihl MS460 that probably had a tree fall on it.
A fragment containing the bolt hole fortunately fits at one edge of the large piece. Thus by gluing it on where it fits, we have an exact location of the bolt hole. This greatly simplifies the job. All gluing and filling is done with JB Weld.
The other bolt hole is only half there, but again gives us the location, which again is very helpful.
Next we build up a spiral cut cylinder of sheet metal. All metal used in this is galvanized stove pipe metal, with the surface ground off. It is glued to the bolt hole fragment and then built up with more glue.
Another piece of metal is glued in as scaffolding.
And then another. This is a build as you go process.
And another.
The other defect is backed by sheet metal. Fortunately the edge of the other hole is preserved.
Maximum photo limit reached. To be continued.
