Thanks for the link to that old AS thread. One of the best I've read and I had not found it in my searches.

i was thinking just for sh@#'s and giggles i'm gonna mount the little earthquake in the mini mill and really run it hard on a couple small logs. that will certainly be a test

Now that should be interesting. Is there a source for ripping chain in 3/8 lopro?

I tried a regular 3/8 .050 chain on the EQ bar...no joy something binds.

because the bar is for 3/8lp,, the drivers are a little shorter then on the 3/8 standard

can the tip 'teeth' be modded? the chain seems to work fine on the drive spur

See the thread I posted above. He goes into this extensively.

thanks...didn't read through the entire thread...only say mods to go from reg to LP, not the other way...looking again

Same principles apply. You can drive out the rivets, remove the sprocket, re-shape it (or install a replacement kit) and reinstall it. A lot of work for a $20 to $30 bar. I assume that there is clearance for the larger pitch sprocket. Lots of little parts (see photos below). Most people would buy a new bar. Mtngun was driven because he could not find off the shelf stuff to meet his needs as I recall.

the bar tip sprocket "teeth" are shorter on lp then on the standard so as far as modding,, waaaay to much work

 

[Philbert]

Again, I think that this is more work than it is worth, but you can buy replacement sprockets for bars with 'non-replaceable' tips. Don't know if a full 3/8 would fit in a bar designed for low pro 3/8. Here is a photo of a NOS kit from eBay just to illustrate.

I don't really understand the point of modifying the bar - the bar is easier to change than the drive sprocket. I don't think anyone makes a full 3/8 drive sprocket that fits the small chassis RedMax saws. And if you can't get a full 3/8 drive sprocket why bother with the bar?

Me neither. I usually run the chain that the manufacturer's engineers think matches the powerhead best. Just trying to help a fellow A.S. with a 'what if' question.

this is a little out there...but I have a 108 dolmar bar that seems to fit the newer saws, (poulan/echo) it has the bigger chain on it?

The Quake in its new holder.

As was said in the other thread, this thing does STINK... :sick:

Seems well made though, don't know that I'd hang the 441 off it, but the Quake should ride along just fine.

Just hope I don't forget its on there one day an end up with a bar holder.... :msp_w00t:

 

[o8f150]

i can't believe what i have started here,, everyone giving up their stihls and huskies for quakes,, thats just wrong:hmm3grin2orange::hmm3grin2orange::hmm3grin2orange:

Scott, you should have them Lock this thread, so that everyone can sober up from this madness
