Burying the tip will definitely increase heat, and will also increase the likelihood of wood chips getting stuck under the bar. It will also slow your cut time, the most efficient cutting part of the bar is the flat part.

Nice to see u'r losing that inbred redneck accent. Yoda wouldn't have been my first choice, but still a nice improvement!
haha. I started the reply and then was attacked by a little girl. Then finished it without proof reading the first part.

Two variables here, one, how much chain deflection if you pull on it say at mid bar at the bottom? Those have to be the same. Those results will be related to chain tightness, which impacts friction. A second way to measure that, no idea...
Maybe he was bored?. Anyway he got to run his saw and had a fun afternoon. I'm sitting here listening to my 2 kids fight.
Wow, that post got pulled? I did not agree with the negative part of it, but also did not think it was over the top!
Calm down Idaho, no point in getting banned.
Well, I'd like to keep seeing your comments, for what it is worth.
The monitors may not always be correct, but they have a tough job to do.
I'm stealing this from someone else but "Stay calm & carry a chainsaw"!!!

You're right dude.
Redbull, would you ever consider a Husqvarna bar post?

Well he likes saws? Try a 390xp just for experimentation!
Redbull, I appreciate your posts a great deal, love the bar pics on your stihls. Nice machines no doubt but would be curious to see your thoughts of a Husqvarna one day. Im on the fence between the 2 and find both have theyre place. Anyhow, there are a lot of respectable people that have been a great help. Thank You. Stay Safe!
I like this post, proves not too much gain running a short bar as some seem to think, that is cutting the same wood. Steve
Keep in mind the 20" bar may be faster in wood that does not exceed 19". When you bury a bar, it is not working as efficiently as it could. Having the 24" cut with their tips may have also slowed them a bit. His test may be reflective of the wood size.

also did this test with the 660 and 461 a while back...
http://www.arboristsite.com/community/threads/660-same-wood-w-20-24-28-32-36-also-461.264521/
----------------------------------------------------
back to this 661 test...based on the fact that times really didn't change much going from 36" down to 24" tips exposed on all of the cuts. To me it seems unlikely there would be much of a difference going down another 4" to 20" even if the wood was say 15" instead of the 19-20" that it was.
--------------------------------------------------------
oh heck here is another one! lol yeah that's right I re-did the 461 test cuz the wood shrunk or something. yeah I did it again this time with the 661 and used the thermal gun to see the temps...which I didn't have on the prior tests.

in this one the 20" is the fastest..but not by much.
In all of these tests it seems the 28" is the top dog...and I think it's IMPORTANT to note - these are NOT the same bars. I've bought and sold and re-bought several times.

The surprising anomaly seems to be that the 28" bar consistently out performs the 24" bar. Other than that, the 20" or 28" always seem to have the fastest times. I'm searching my mind for a logical explanation, and coming up empty. I know you used factory RS, but could it just be the chain?

Mike, yeah in this one the 20" and 24" tip had from what I can tell the same amount of tip exposure out of the wood and the times ended up like so...
20" 15.0 14.7
24" 15.9 15.6
28" 15.3 15.4
32" 15.8 16.4
36" 17.5 17.2
interesting the 28" beat the 24". Well there is something to be said for the 28" bar on the 461, 660, & 661.
http://www.arboristsite.com/community/threads/stihl-461-different-length-bars-in-same-wood.267226/
I dunno man. that's 4 different tests, with multiple new chains, multiple different bars, and 3 different saws. I dunno...something to be said about the 28". At least on 461 660 & 661.
