I bought one
Priceless
Used to dread messing with recoils
Now striping down and cleaning the spring is part of servicing
my ebay decals just arrived. same guy that did the ones for my SP70. top quality work IMO.
Which seller was it?
Is that from Sugar Creek Supply I’ve used there’s good quality stuff .
Keep rolling, rolling rolling
Rawwwww hiiiiiiide!! Set em up..........rolliiiiiin
It's just a fly in the ointment Max.It's been snowing in southern N.Y.,not by me though,thank God.You'll get good weather yet.
I was pretty stoked to get the 28" bar and chain with my new to me 10-10S. as I mentioned earlier, I installed them on my SP70.
something isn't right. the chain is sloppy in the groove and doesn't ride right on the nose sprocket. on the nose the chain rides up higher on the top and rides over to one side more than the other. when I got these, I cleaned out the groove and cleaned the nose sprocket and greased the nose sprocket. the nose sprocket is tight with no play and rotates smoothly. the markings on the bar tell me it is 3/8 pitch, but I don't know how to tell what the gauge of the bar is. there is an FQ marking on the bar, but I have googled that and the other number and get nothing. maybe too old for Oregon to list.
the number 72 on the drive link of the Oregon chain tells me it is 3/8 pitch/.050 gauge.
I checked the drive link thickness on the chain with a micrometer and got .507 in. I checked the width of the bar groove with feeler gauges and got .060.
so, either the groove in the bar is worn out or the PO was running a .050 gauge chain in a .058 gauge bar.
can anyone translate the bar markings to determine gauge?

280---D176
28=28" 0=.050 as in 8=.058 , 3=.063
Oregon chain is 72=050,73=058,75=.063
Its a 050 but very worn , a pinch in the groove might be making the chain ride up.

thanks for the info. so, probably a stupid question but is it possible to run a .058 chain or is this bar kaput?
Yes, but I also like to put a rail squeezer on them worn bars also , you're likely not to be able to get it back to 050 but definitely . 058 . Ive done it before with a couple of vintage bars with very good results.
I googled that and found this. they all look like this same one except for a stainless steel one on ebay.

Yup that one looks similar to mine.
looks like it would be pretty easy to make one...
I have the Baileys unit, you have to learn to work with it as you don't simply dial in the gap you want and pull it down the bar. Lots of little adjustments, pull and check, adjust, etc....
You also have to learn to lift it as you approach the sprocket nose of the bar...unless you take the nose completely off.

that one looks more heavy duty. I looked on Bailey's website, apparently don't carry it anymore.
Near 30.00 on online stores plus shipping. Search bar rail closer. A few stores have them. Ebay does also. Ive used one with good results. It takes a little effort. It wont close a rail up in one pass. But like most things with patience they will work well.
