    This press seems to be the overwhelming favorite on these boards. Can this drill press be used to mill pockets or is there a better tool to do both axles and pockets?

    Technically no drill press should be used as a mill. The Proxxon drill press is a petite little thing, and I don't think it would live long being used as a mill.
    I recommend a small router to cut your weight pockets, however there are several ways to skin a cat.

    One attempt at Bulldogs routing of a body and that was enough for me. Cut the pockets all the way out of the body and glue 1/64 ply down on the top. Works wonders, is clean and you don’t loose your mind.
    Don’t get me wrong, routing is wonderful if you have the right set up and skills to use it.
    But for me simply gluing the ply down was 1000% easier. Gluing ply is how we do league car ladder bodies too. Works real well.
    Just another option.
    Hope that helps.

    Use the drill press to drill pilot holes and use a scroll saw to cut the body, then use plywood to top it....

    That is the easiest way I have found

    Do what I did, use this as an excuse to buy a CNC router!

    I guess it begs the question. Do I need a drill press? What's the advantage? The sbe seems to imply that a hand drill or pin vice is preferred anyhow.
    I don't understand 1/64 ply. Are you saying cut all the way through the body and then glue a laminate over the top to cover the weights?

    What Mojo said is the easiest way in my opinion. Cut the body with a scroll saw and then hand sand the body from there.

    Yes.

    Cut all the way through the body and use a laminate. Michaels sells sheets of 1/64" birch plywood that works perfect.

    Some people cover just the weight pockets, some people cover the top of the car, and some people cover the top and the bottom from the weight pockets forward... it is your choice on how you want to build, but cutting through the body is faster and WAY easier than setting up an X-Y on your drill or mill or trying to router the body out.

    Oh, you need a drill press, simply for prep & polishing wheels & axles,, set the speed on low.
    Didn't you want one anyway, this is your reason.

    I did want one anyway. Just needed a good reason. Thanks! Is there a good all around press people like? The little ones are nice but not sure useful for other projects.

    I went the Horrible Freight route.
    All I use it for is drilling corner guide holes in blocks before I route out the weight pockets "different tool" & prepping wheels & axles.
    It was worth the $60 just to get away from holding a drill in one hand trying to stab a wheel & the kid can prep his own stuff sitting on a stool.
    It comes in handy when also used for it's intended purpose.

    Just like Mojo said...
    Table saw to cut my 1/4” blanks. Drill press for a hole in each section. Scroll saw to cut. Glued 1/64 ply over weight pocket, added balsa ribs. Sand to finish on the belt sander.
    Not as pretty and perfect as a laser cut body but it works just fine.

    I did the same, under the guise that I'd use it for other stuff. ;)
    The ladder bodies that I've cut with the CNC router are amazing. I've been able to cut the weight pockets, and ladder, leaving a top (cutting the body upside down) that's so thin that it's translucent. I got one down to 7 grams. I also drew up some full fenders, and cut them out of balsa wood.

    I bought a mini-mill from micro mark to use as a mill for cutting weight pockets and as a drill press. You can also use it to cut ladder slots. Use a dremel on a stand for axles and a small battery powered hand drill for slow speed wheel bor polishing.
