advice for a noobie chainsaw user

[NI Tree]

what type of engineering do you do

[Eddy_t]

20 micro is a bit anal, if you did that, you'd never accept any bar! On a flat table is enough

milling machine and lathe operator, tool maker, bench fitting and surface grinders

well on a flat table its about a 2mm gap at the centre of the bar, laying flat.

it is bowed slightly.

if all the wear is on one side only i would say that piece of the bar is made of paper mache, as you are a tool maker im sure you are aware of hardening and tempering.

 

so either this piece of the bar as not had it done so its nice and soft or it has not been done properly.

 

new bar if its worth it.

[chrismechanic]

yes im familliar with this, as i said in my previous post i think that is the problem here...

 

i think i will drop mcculloch uk an email. maybe they want to send me a new bar.

thanks for all your help guys ill let ya know what they said..

ask for a bar like this one:thumbup::lol:

yer i like it.. would look amazing if they all had light sabre's

 

i finnished checking tooth length's.. some are longer than others by to to .50mm, im now trying to get them all the same length..

I'm not an expert but your depth guides might need some attention as well while you are sharpening the teeth.

I'd not too fixated on cutter length - most people I know end up slightly heavy on one side when hand sharpening and it's never made a noticable difference.

 

In my experience, a curved cut is nearly always the chain rocking in the groove (so either worn drive links or worn bar rails) or the rails being uneven heights (usually a result of the first going unnoticed for a while).

 

Either way, I'd not expect to encounter any of those problems in 3 sessions of cutting a few logs.

funny you should say that... i was just looking at that and apart from the tool, how would i check that... would a straight edge from tooth to tooth and then measure the gap be ok?

 

if i do measure it that way i get around .35mm so they do need attention.

thanks..
