belt sander but be careful though lol, and it wont come out uniform, palm sander will knock off the strait edge a lil

its best to just invest in a router. It such a multi purpose tool theres no reason not to have one.. ;)

but otherwise, if u have a sander, thats ur best bet but it wont get as deep as a roundover bit

take a circle and cut 45's off and then sand.

file and 60grit sandpaper will do the job pretty quickly as MDF is pretty soft...

Break the edges with 40 grit on a grinding wheel and use a hand block to round the edges with 40 grit again. It takes a little more work than running a round over bit but the result is a bit nicer.

**** I thought he really wanted to round the edges if you are just trying to accomplish that then 40 grit and a palm sander will work wounders.

you have all these grinders, but did not figure out, that you can maybe use one to grind the edge of the box to be round. I mean you can do the same thing with sand paper.

sandpaper is gonna take forever, I'm gonna see if I can use a grinding wheel. I don't wanna fvck up the mdf.

Just buy a router. It's the only tool that you would need to build a box that you don't actually need if you don't have one.

If your just looking for smooth enough to take the sharp edges off, use sand paper.

Otherwise get a router

random orbit sander.. good way to round off every sharp edge on a box in 10 seconds flat :cool:

Just grab a 2" wide wood rasp, it'll shave the corners faster than a sander, and then a bit of elbow grease with some 60grit and you'll be fine. Exactly how I just did mine yesterday, and it turned out perfect.

Just rent a router. ie: buy one then return it when you are done.
I have never done this myself nor do I condone it but a friend of mine says he see's it happen all the time where he works.

It'll take the edges right off. They're quite cheap at harbor freight and such (like $5), and it'll do it just as fast as a router

it's a good cheap option, but the worst routerer on earth couldn't be beat by a rasp.

I highly doubt it will do it as fast and as clean as a router.

Well, its fast lol.... Maybe not as fast as a router.

After some 60 grit (following the rasp) you won't tell a difference from a router once painted. I did mine yesterday (and I have a router too, didn't feel like taking it out lol), and it turned out fine.

Just a cheap alternative

I wish i had about 6 routers so i didnt have to change the bits and all that. gets annoying as ****. but they are a life saver.

Thats the reason I didnt use mine lol. I got a nice carbon bit set for x-mas too (30 some bits) and haven't even used any lol. I just needed a corner rounded, and it was either take out the rasp and do it. Or pull and extension cord out, take the router case outta the cabinet, plug that all in, get bits out and put in, get glasses... just seemed like a PITA because I was in a hurry, and didn't want a mess

understandable. if it was the whole box i would say you are an idiot for not using a router. but it wasnt so your not.:D

Router is a good investment. Just go to your local pawn shop and pick up a used one, and a $50 variety bit set from ebay.

If your painting your box duraglass is your friend, use it to fill in the seems and sand it down. I recomend using a catylized primer and an automotive paint.

Except, it won't.

that looks like a hand tool, so it'll just depends on how much he loves himself to determine how fast he can go

What kind of beastly drill do you have? all a router is is a HUGE motor, one far more powerful than even the strongest drill.
