Carving bar Chain lift before nose?

Recommended Posts

Never had this before, been using carving bars for getting on 10 years now, c06867fddcefd21337854f091770ddaf.jpg46a7fa4ff9b81ce33bf00d9098e4bc3c.jpg

 

Chain being a fool, sucker, just before nose, bar is dressed nice, all square rails even wear, tried with 2 chains (both new) same thing, new sprocket.

 

When you run the chain it appears to tighten, then if you pull it or put the brake on it slackens off again.

 

Def not drive links bottoming out as if you push it down it'll sit back

 

Just thought some other carver might of had same problems

 

Foolish sucker

Run a straight edge across the top of that bar, it does appear to have adopted in it, worth a try as you have done everything else ....

Looks like a couple of seized links in the chain from the pic. Dunno if this could be causing it.?.??

Groove is clean, I thought it was a siezed links until I noticed it did it on everyone all the way round the chain and the 2nd new chain didn't solve it.

 

I have used the saw again today and seems to be doing it a bit less, potentially it was some burring from when dressed the rails (burring across to inside of rails?)

You have a lot of peening on the tie straps on both chains but particualrly the chain on the right which looks to be new ish.

 

This may or may not be related to what is going on with the chain riding up but it is not normal.

 

Obvious cause is worn drive sprocket.... but may not be this but worth getting to the bottom of why that is happening.

Thanks Rob, it's a used bar I bought with 5 new chains, the one that's on was peened when I got it, the bar did need dressing so I did this, fairly sure the previous owner had a goosed sprocket.

 

Thanks
