I posted this earlier and one person even replied but the thread disappeared, trying again. I did post the images (only) through Tapatalk (in the original thread), wonder if Tapatalk is the cause of the disappearance. My brother has this old electric, corded chainsaw, Sears brand. Wanted me to sharpen it but it looks unlike anything I have ever seen. Look at the teeth... they appear to have been manufactured at a 45 degree angle. Rakers are also highly angled. Any idea what this chain was for or was it just some weird saw for cutting trees? I found an old parts diagram and it said chain no longer available and no substitution exists. But... I did find a parts number matchup but not sure if the Oregon chain fits this model. I did not see a Craftsman model number match but I forgot to look for 'Sears.' Seems to me a chain could be found but what do I know!
Speaking of disappearing threads, did you post something about a red oak log today? Where is that thread?
Something weird happened today with the FHC server (I presume), and many threads/replies from last night through early afternoon today were lost. As for the chain, the drive links look standard. I wonder if you were to measure the pitch and bar groove width if you could just run a standard type chain? Very cool roller nose bar too
Looks sorta like one of those chains that self sharpen with a stone on the nose. Thought that gimmick was newer tho.
over the years there have various types of chain designed for auto/self sharpening on the bar with some sort of attachment or built in stone system. ( latest one I know of is from Oregon) I have seen that style chain in the past, long time ago , it was a self sharpening one . Frankly I consider most of that stuff a sales gimmick. Like was mentioned above check the rivet spacing and the height of the cutters to see what might might be a decent replacement. With everything from .043 x .25 pico pico on up there is likely something that wood work.
Bingo, that sounds familiar! Now I see that you did, in fact, nail it with a post below your first! Thank you! I knew something was strange! He is kind of timid with the Stihl 290 they have, he doesn't want to use it. He wants to cut some small stuff now and then that he can drag up and cut for firewood. I note that the name of the saw is "Power Sharp!" I hope it will accept a regular chain.
I sure did! It's gone too! Back to the saw... I did notice that the nose looked different, there is a gap between the chain and the bar. Self-sharpening, I suppose, answers that. I guess the sharpening gizmo is long gone.
Here's an old Sears Powersharp. Made by Poulan or <someone else, I'm drawing a blank, name like Bolen or somesouch>
My dad has a sears saw like that one. It has a built in sharpening stone that you activate with that black knob on the sprocket cover. Never worked worth a chit. Not sure about a replacement chain, but I’m sure a saw shop could come up with the correct gauge and pitch that would work for it. Just wouldn’t be the self sharpening profile. I think next time I’m at his place I’m going to grab it and see if I can make a chain for it and possibly use it some to cut tree service wood dumped in the backyard. Been years since I ran the thing, but seems like it had a lot of torque if memory serves.
Ok, thanks for posting, now I know something about the auto-sharpener! It says "push lever to oil chain" on the placard. Anyone know how often you're supposed to do this? If that oiler doesn't work, it wouldn't be worth attempting a retro-fit chain.
Honestly don’t now I would have to say at least every 5 to 10 seconds you figure on out gas saws if the chain is spinning the oiler is oiling
interesting. So if your right and it looks as if you are the stone and mechanism would be under the chain cover. Yawner have you looked under that cover yet?
Oh, wow, now I see what you mean, lol. I am not where the saw is anymore, will have to check it whenever I am, which could be awhile. Maybe my brother will do it.
