New 880

[Mike Black]

Fantastic benches.

[Pinkfoot]

Nothing to be coy about there ..

[Rob D]

Excellent work indeed and original designs nothing to worry about there ...

 

Great work - really good to see so many milling and making things out of timber we have in this country...

So, the 880. Wasn't bedding in. I apparently melted clutch due to running with too tight a chain.

 

Used to 15-18" bar. 44" bar a new world of tensioning!

Any thoughts?

[Mike Black]

I mean wasn't lack of bedding in!

[Rob D]

Hmmm - it is actually hard to over tension a long bar on the MS880! You must have cranked on a fair bit to burn the clutch!

 

 

Learning process as always - next time half a turn off and should be fine. That chain on a long bar should not snap back to stationary the same as it does on a smaller saw.

Guys who aren't used to long bars always try to run the chains too tight, running a long bar and chain is a different skill set to running short bars, all the tips and tricks you learn on shorties go out the window when you get on 42" plus.

[Mike Black]

I did over tighten. I overreacted to seeing chain flopping about. There was also occasional sparks - I believe the chain was catching the mill around the tip of bar.

Any advise there?

 

Thanks Rob and Peter... It really is way different from running shorter bars.

 

Was milling metre lengths of Elm. Building up to a huge burred Elm that awaits milling.

Mike, there's a guy near here who's been milling since forever.... His technique is to have the chain so loose it nearly hangs off the underneath of the bar. I know what you're saying about the chain catching the mill, the centrifugal forces forces it away from the bar. The looser it is the more it travels and trashes the teeth on the mill. Our mill has a nearly sawed-through 8mm bolt in evidence of this. Thus the overtightened chain. I have in mind to modify our mill so it doesn't do this anymore. Maybe your mill could be modified?

 

Also have you considered an auxiliary oiler on the return after the bar nose?

 

Also (am I teaching granny to suck eggs?) wedge the planks behind you as you go.

Thanks, Haironyourchest. Will certainly run chain looser in future. Yes, was wedging.

 

Modifying sounds interesting. As does the auxiliary oiler.

 

Get saw back this week. Off for week on holiday. Will return to fray soon after.

Will certainly take on board Rob's points about resting saw etc...
