Teyhan1 has already answered the question regarding the ripping chain. Once fitted to your bar, be very careful not to use your chainsaw except when fitted to the mill. The different characteristics of ripping chains means that they are susceptible to kick back, if not used in conjunction with a mill.Yep looks ace. whats the difference with a ripping chain?
What did you finish your wood with?
i was thinking a 48" mill so it give me more options for milling bigger logs.
How often does the chain need sharpening?
I finished my wood with tung oil, which gives a nice look and is food safe. Takes around 4 coats to seal and then repeat once a year to maintain protection.
The chain needs to be sharpened fairly regularly, so having spare chains can be a good idea, although it is a bit of a faff taking your saw out of the mill each time to do change them over.
Wood type dictates how often you need to sharpen your chain. If the bark is dirty, then this can dull your blade very quickly, so worth pre-cleaning as much as possible or even de-barking if desired.
