ripping 90x90 x2.5mm rhs

G'day,



got an interesting situation where I may have to rip down a piece of rhs - 90x90x2.5 mm.



now, my first instinct is to fit an abrasive cutting disk to the circular saw on the triton and run it along the fence.





wise or not wise?





i will be nesting the halves and welding them to form a section 92.5mm x 43mm.



this is the closest I could find to an internal sleeve for a 100x50x2 mm rhs joist.





i don't want to free hand with the anglegrinder and I can't for the life of me find an off the shelf alternative from any of the main players.





all to save on the exorbitant internal rhs sleeve joiner costs which at 17$-26$ for approx 300mm is just too hard to swallow.



I need quite a few of them you see?



the other alternative is butt welding the cut joist sections to form the lengths required, but I can't decide whether this will be structurally as strong (or strong enough)?



i would simply run a single 6013 bead down the join all around. 7016 /18 probably penetrating a little too much for my liking : )





no mig available .
