Hi.
I have earlier had some issues with my Carvex when it comes to making perpendicular cuts.
It "never" cuts perpendicular.. well 2 of 20 cuts I have done has actually been perfect perpendicular, the rest has been slightly off to way off. But I have so far been thinking that this has been caused by the material or "user error" so I have been a bit forgiving with it. But the trend is always that the cut starts out straight and the blade starts to deflected away from straight along the cut more and more.
I have always paid attention to adjust the blade guide as described in the manual, which simply means: Closing the gap but leave it with a slight clearance to the blade so it can slightly wobble a bit. (Release the screw 1/4 to 1/2 turn after the blade guide touches the blade).
But my Carvex has now entered a new universe when it comes to "accuracy". it simply "destroys" both blades and the material it is put to work on. It also creates sparks from the blade guide when the blade is bent sideways sufficiently.
I can also mention that my carvex has been used very little, its total cutting length is only a few meters in soft wood since it came out of the box brand new.
I will now send my Carvex back for service/repair.
But I will like to share the following information with you.
I have done the following test:
Cutting trough a 48mm (2inch) plank of pine (cu impregnated). I attached a straight piece of panel to feed the carvex along to make the cut straight. The splinterguard was in place but "old".
Both blades was nearly new.
Pendulum action was set to "2".
I pushed the Carvex along the cut with just weak force.
Image001: The long cut is done with a S75/4 K blade, the short cut is done with a S75/4 FSG blade.
Image002: The long cut seen from the underside.
Image003: Underside of the long cut where it begins. It is aprox 21mm from the edge of the plank.
Image004: Underside of the long cut where it ends. It is aprox 37mm from the edge of the plank.
Image005: The S75/4 K blade is bendt after use.
Image006: S75/4 K blade after use.
Changed blade and adjusted the blade guide:
Image007: Underside of short cut made with S75/4 FSG blade. (Clearly drifting towards edge of plank).
Image008: The S75/4 FSG blade is not bendt, but shows signs of heat friction (blue) from the blade guide.
Image009: Other side of S75/4 FSG blade.
Conclusion: The cuts drifts to the left indenpendently of the blades used, and independent of the structure in the material. Since the cuts was done in opposite directions.
So if your Carvex has signs of not cutting perpendicular it can suddenly escalate.
This machine has been marketed as exelent in making perpendicular cuts, so than you shall expect that as well!
