easy rounded corners

[Chris8sirhC]

I just got this new catalog in today, and i saw somethign very interesting in it. Basically it is a shaped length of MDF that allows you to attatch two 3/4'' pieces of mdf at a 90 degree angle, but you end up with a corner that has a circular radius of 3''

The picture shows plywood, I'm sure you could use most anything. Looks promising. Thanks.

No, it shows MDF. Did you punch in the right numbers?

You could also just build your box the way you usually do, and use something like this:


(Since I don't know the english word for this thingie, I use a picture... A pictures says more than a thousand words)

I don't think the wood joint with a strip like that will be as strong as a normal joint (using glue and screws).

But for building furniture (at places where no strength is necessary) it looks VERY interesting!

That’s a router, but at best you can round over to the thickness of the material you are working with.

This stuff above can do round over in the inches.

Yessss....ROUTER...that's the word I was looking for (only the word Chisel came into my mind).

the joint would be as strong as another glued joint. You are still glueing mdf to mdf. YOu just have twice as many joints to fail or leak but should be strong enough.
especially if you laminate the box. you can still use screws or staples before you laminate.

Another use, in case your still worried about a loss of strength, is to build the regular square box, then mount the mdf corners on the sides of the box, and fill in the gap with something like sand. That way you can have a box with the same strength(?) and ease of constrution, and still have the 3'' radius corners on the box. Currently i am doing something similar, the only difference is that the line arrays are only 3'' deep, so all i have to do is mount the solid half rounds to the side. It ends up looking similar to that crushed sonotube project someone created a while ago, except smaller in stature.

You could use extra shelf braces. I agree with the Timn8ter-- looks worth investigating to me.

There are several companies that sell preformed MDF rounds like these. Seems to be the way to go if you want a 3" roundover.
