stihl hard nose bars

[joed1694]

tell me the pros and cons against hard nose bars? I think there oughta be a sprocket on the end of that thang!

When I began cutting in the early 70's, people all used hard-nosed bars. They were considered the most durable. I used them exclusively until about mid 80's. They are very rigid and hold up well, but you must run your chain more loosely as there is considerable friction. They are hard on the drive links as the bar noses are usually welded with a hardened alloy (not being a metallurgist (sp?), I don't remember what it is exactly, but it is hard. Having a sprocket nose allows you to run your chain taut and I believe you get more chain life (at least that has been my experience). I still have some hard nosed bars for the Wiz and Super XL-925, Super XL-12, and the Super Mini VI.

Even the new sprocket nose bars still act like a hard nose, note that the sprocket turns and not the rails if you will. The old roller nose was a true roller although they were outlawed in the late 70's I believe. Just my 2 cents

Hardnos will surive in dirty, gritty cutting situations that will seize a sprocketnose. The hardened alloy at leastin modern hardnoses is stellite I think. I see quite a few of them on construction sites adn by one tree guy I know. I have a 10" for my Homie but other than that I really ahven't used one,

I think I recall a thread on this like last week. Try a search and see what comes up. Hardnose are for cutting in dirty stuff, but you usally have to run your chain looser so as to not overheat it, and I think as far as durability, a modern sprocket nose bar is just as tough, and I'd think it'd take alot of dirt to make the hardnose worth it.

I know that you probably have forgotten more than I will ever know about saws, but I don't think there is much contact between the chain and the nose radius of the bar when you have a sprocket nose...

Robert, what was the issue with roller-nose bars that brought about a ban? My probably-will-never-run-again-but-I-still-have-hope Remington has one - should I be concernd using it on this or whatever saw I may wind up putting it on?

Yes it's real dangerous, you can send it to me and I will take care of it for you.

These are in demand still, when you can find them. I would like to find some to use with my saws.

Wasn't it mentioned here awhile back that those hardnose bars were good if you did a lot of bore, plunge type cutting.
