radius on edge of MDF
Afternoon
I'm currently mucking around with layouts for a dashboard made from 9mm MDF
I'd like to put a 9mm radius (same as the thickness) on the top edge to blend it in to the scuttle and wondered apart from using a router which
I don't have if there is some clever technique to get a reasonably uniform radius.
Any tips or tricks appreciated.
Cheers
Nigel

a light hand and a flapper wheel, believe it or not I use one of these to carve balsa for r/c plane nosecones.

quite right and best to do it outside so the dust isn't floating around the garage.

Or if you know someone with a router and a suitable bullnose router bit you can do a really fine job!!!

Power sanders are the easiest way, if you era confident using them.
A block with some course paper will eat through MDF pretty quickly too.

Are you planning to cover it with foam and vinyl? If so then don't worry too much about getting it perfectly uniform as the padding and
covering will smooth it out quite a bit.

Wrap a piece of sandpaper around a piece of wood with the same radius as the one you want. A piece of beading/moulding should do it.
BTW MDF is now safe to eat. They don't use arsnic in the manufacture anymore. Apparently!

Tack/glue a piece of 9mm 1/4 round wooden beading to the edge. They sell it in DIY stores. It's usually in a rack of all shapes and sizes.

Use a plane to take the sharp corner off then sand it down. I wouldn't do it without a mask as they still use formaldehyde in a lot of the
manufacture of fibreboard, never heard of the arsenic problem.

I went into the RSPCA office the other day. It was so small you could hardly swing a cat in there.

MDF production.
Formaldehyde is still a problem. Here is a bit about it. I worked in a cardboard factory and it
was used in the manufacturing process, some people are more resistant to its effects, I'm not one of them it chokes me.

take it to a joiners shop and get them to whack it through their spindle moulder, if you go with a beer or two in hand you will be in luck.
