Hey Joe,
mmmmm thought I might be able to help out here....
"The bar appears to be made of cheese, as is the chain, the chain got blunt so I had it professionally sharpened on a jig, it was razor sharp for about a week, now it is blunt again."
I used to have a Sthil 16" bar wood boss with a big motor on it
(i cannot remember how many cc's)
I used to cut alot of red gum and white Mallee with it, I dont think there is much wrong with the chain a good sthil one (3/8) would need a touch up after a trailer load cut into 350 400mm long bits......I digress.... I found that the best thing for bar wear and heat was to add Nulon diesel engine treatment to the Sthil bar oil,
an amazing difference!! I just had the Nulon in the shed and thought %^$*&$() why not!
Note: all chains have a long bed in period and dont foget to flip the bar over and de-bur the sides with a flat millsaw / bastard file. I was on my second chain after about 7-8 5'x7' trailer loads.
some bastard knocked over the shed so I no longer have the Sthil, but I think I still have a spare chain...
.....Keep the chain and Bar out of the dirt!!!! that also helps......
I think I need a beer....
no wonder we went to gas heating....
