an old favorite?

I've gone thru all of these, and I may have missed this one, but it probably bears repeating. I'm sure many have encountered this problem.
The PO of my bike made a big deal out of changing the oil, specifically installing the new filter. My first change, I saw that the oil filter bolt had seen better days, but it was OK for one last use.
When I went for change #2, having bought a new bolt, I found that the old one didn't want to break loose, and I rounded it a tad more trying to remove it.
In the past I have used a die grinder to shave a bolt down to the next size, and gotten it out. No die grinder available now, and not much room to use a file.
Any solutions for a limited shop?

VIce grips and a hammer? Dremmel to cut a groove for a screw driver? Use a cold chisel on the edge with a hammer to break it loose.

I got mine off with an 8" pipe wrench a short piece of 3/4" diameter pipe can be used for extra leverage if needed.

Slightly small 8 point impact wrench socket tapped on with a hammer and then rip it off with the air impact. Impact wrench needed oiling anyways.

It is tight behind the filter cup, but with a strap wrench, it should turn just a little one way and then the other to try and break the thread's "stickshun". It will ony turn about an 8th to a quarter inch maximum...

Thanks Skids. That might work.
As for the vise grips, hammers, pipe wrenches and impact tools; did I run over all your collective dogs? It sounds like you guys want me snap off this puppy.
This bike isn't on a lift, so space is limited. No compressor in the garage either.
I guess I asked the wrong question, but there's a way to do anything-
I'll find one. Thanks.

No compressor would make it a problem. However, I don't have a lift either, but I do have a compressor, and it did get it off without damage other than the bolt now being stuck on the socket I used. Replaced it with a good used one and it's all good now.

I had the same problem at last oil change and I just tapped it round with a cold chisel. Not hard hits, just gentle taps till it broke loose. The I filed it to a smaller size and used a 6 point socket to put it back on. Have a new bolt now but will wait till next change to fit it. I wont ever use a 12 point socket on that bolt again, if the 12 point socket or the bolt is even slightly worn you risk slipping and stripping the head.

Once you get it apart, take the bolt to a machine shop and have then weld on a larger nut right over the rounded-off head. You'll never have another problem with rounding!
