Speccing a sawblade

[fatgraderman]

A couple months ago I bought a circular sawmill setup for a 48” blade but it didn’t come with a blade. I’m trying to get my order info correct. If I go 6 gauge, will the holders still be 6 gauge? Do them make them for whatever gauge holder you want to go with? Do you guys normally go with the heavier center? Why do they list them as 6/7 or 7/8? The one guy I have had helping goes by plate thickness- .180”, .203”, .220”, etc. just trying to get this ordered up as there’s 6-8 weeks lead time but it’s a bit over my head.
