Stihl 090 Cannon 84" Bar Slab Build
« on: September 30, 2018, 04:14:33 AM »
Been building and developing my lumber business. This has been a long build that has stretched a few months and soon to go on a year of the first purchase of my 090 and bar. I have been fabricating a frame for the mill itself. Used 2" Square tube for my frame. And 1" square tube for auxiliary framing. A lot of little customized additions as well. Stay tuned for constant updates, and questions!

Very cool, that is going to be a beast! Do you have a way to dry your slabs or you sell them green?
Looking forward to a video of this when you get it together.

Looks like a nice set up. Does that bar use 2 saw heads?

No unfortunately its only 1 power head, 090 seemed like enough for now, I hope... I could probably do a dual system, just need another power head and bar. But that's a lot of cost, I should be able to get 1ft/min. I have plenty of room to store and dry out the slabs, 28 acres, and a kiln is in the making, a solar powered shipping container. Currently, I have 1 customer that wants maple slabs 2" thick as wide as possible, and doesn't mind taking them rough sawn and green. I'm also going to start putting adds up on FB and slowly move into tables and such. This saw is for slabbing, or cutting big logs in manageable cads. A lot of theories and speculations are going into this slabbing build. Thankfully everything has worked out pretty good. Gotta build the brackets for the tanks of the auxiliary oilier, fuel, power head oilier, and the systems for between, I already have most of the fittings and hoses.

Is there any problem with drilling holes in my bar then securing the bar with flat stock and all thread? I like 5/8 for the all thread. Thoughts, concerns, advice?

Make sure you can take the bar off easily. It will need to be dressed and flipped every so often so that it wears evenly

Cool build!

I drilled through a pretty tired 36" bar for 1/2-13 threaded rod on this home made alaskan.  It works fine but bars are pretty hard, youll need a good hardened drill, carbide if possible and in a pretty slow drillpress.  A bridgeport would be better, youll wanna be down around 200-300 rpm and with a good cutting fluid.  


I drilled through a 24" bar for a track and cantilever carriage sawmill i built also. Used a pair of 3/8s bolts next to the powerhead to fasten it to the steel mount on the carriage and hold everything up.  The bar floats freely so its not supported at the sprocket end.  It works fine, neither bar has had anything bad happen yet but with an 84 youll need a sprocket end support.  Just dont try clamping the bar tip.  Itll wreck the bearing.  Make sure you drill far enough away from the sprocket to miss the tang.

Where or what is the chainsaw bar tang?? Is it like a insert into the bar from the tip that is hidden?

Yeah the bar tip insert extends into the bar between the cheek plates a bit deeper than the rivet.  Just look at a pic of a new sprocket insert and youll get it.

If i was gonna do it again i would probably buy 2 good forged american made C clamps from the welding shop, and weld them to the posts.  Loosen claps, pop the saw right out.  Just need to be sure the throats are deep enough to clamp centered on the bar and still clear the cutter.  And jig it up real square for the first tack and triple check before finishing.  You cant clamp the sprocket tip anywhere near the bearing, itll pinch and cook immediately.  Its gotta be behind the rivet.
