    I have been toying with trying to use something like this to face the 2 x 4s once the cnc router is built. The 1/2 in collet version of these bits are not that wide, so certainly multiple passes are needed - and then the cutting is still across the grain.

    I have also seen 4 inch long router bits that in concept at least, could be set up sort of like a jointer / planer, capable of 2 x 4 use. I realize that the boards would not always end up with 4 flat / square sides, but if you saw how my hand sanding is coming out, you can imagine that anything might be better.

    Besides the obvious - a planer and jointer would be better aspect, is there anything fundametal that I am missing ?

    Thanks
    You'll find with your first method that unless you take very light passes, it's easy for one of the edges to get a lot of tearout, due to the direction of the cutter rotation.

    And when trying to use a long, straight bit as a jointer, runout becomes a problem, as well at tool flex. If you can minimize the runout, it may work, but you'll get a LOT of chatter due to lack of rigidity and tool flex. The shorter the tool, the better the results, whether handheld router or CNC router.

    I'd recommend finding a used 12" portable planer on Ebay. You can probably pick one up for around $100 if you wait long enough. They'll make short work of cleaning up 2x4's. And they usually give an exceptional finish. My old Delta does, and I've had it for 15 years. Oh, yeah. It's smaller than a chopsaw, too.

    Thank you for the reply. Space is very limited. The cnc router project is a hobby, so while its economics are important, its price viability vs a small planer is not the issue. While those bits are expensive, they replacement blades are not bad. I am not sure if they just self align when replaced or if there is more to it.

    Space - if I had space, I would (want to) buy many things. Basically, there is no space - I hang the chop saw on its side on the wall when not in use. The cnc router is being designed with a vertical Y axis and horizotal X x Z axis to reduce space consumption, if that gives you a hint. It is a small 2 car garage, with wife's car, kid's bikes and other stuff sharing it.

    GER21 - Those are good technical points about chatter. As far as smaller than a dewalt portable chop saw - maybe - certainly not when I hang it on the wall.

    Maybe I should rig a small portable belt sander up with some 40 grit on the cnc ? jk. So now the task is - can I shoe horn a small planer into the cnc frame ? Maybe.

    Thanks Gerry - but - it is only an 8 ft ceiling, and almost 1.5 ft of it is already in use. There are already cabinets built into the ceiling area, and my bike hangs down from a rope as well.

    When I get some things caught up, I will post some router pics and how it is shaped to just fit on the build thread.

    Re: Jointer question

    Hey,

    Actually I don't have much idea about the portable jointer and I want to know a-lot about it. I am a hobbyist of woodworking and doing some home projects on my own. Therefor, I read many blogs about jointer like benchtop jointer reviews and it helps me too much. Can you share with me a good tutorial regarding this?

    best benchtop jointer

    One of the best benchtop jointer options, the Porter-Cable offering, comes with a variable speed. You have access to variable speed of 6000 to 11000 rpm. You can choose the right speed based on the hardness of the material and the type of finish you are looking for. https://bestjointer.co/best-benchtop-jointer/
