kind of a cool blade when its finished but not at the price of a black eye and or cuncussion and or skull fracture
that hammer did not look like it was made of very soft steel tho :unsure:
Azur here is a video i found on youtube about making charcoal from what i have researched that to make sure to keep the hardwood seperate from the softwood when making the charcoal and using the charcoal
also check a napa parts store and or another parts store they might have what you need (I say napa because my dad owns one and has a large selection of switches)
plus most of there switches are made for the trucking and farming industries
atf or diesel fuel/ kerosene should work just fine for a flush, but ive also read of ppl useing a pressure washer to get crud and gunk out of the gearboxes
as for the preferred lube a light machine oil or motor oil is what i would use
i might have to vent one with my .223 :) but then again i would pry use the water method and cut it open while its full of water.
i also agree with glenn about having a pro do it for me better safe than sorry
i normaly use a log cabin style boyscout fire out off old shiping crates and pallets i just get a good wood fire going then dump hand fulls of coal on top has worked for me for ever
