Rounding off Redwood

[chiangrai]

I have a lot of new redwood window frames and doorframes already installed but there is no glass in the windows and no doors in the frames.They were all made in the lumder yard.

So they look very angular with all sharp edges which looks wrong with my rustic house.

So I was thinking of taking off the sharp edges before I stain and varnish them.I've done this before on a small scale and it looks great to me.

I allways used a rasp before but this time I have so much to do I need to use a power tool.

But what power tool and what attatchment.

If your just trying to round down the edges then why not use a palm sander?

Otherwise you may want to use a router bit, if you're looking for fast perfection.

You can get a bit for a router that will do that. You have to finish the inside corners by hand if you want them uniform. You can also leave the corners as is. The bit won't go into the inside corners and leave them square, but you might think that looks OK too. It does round them off.

The bits come in different radii depending. This is 3/4 inch and you might want smaller for a less dramatic effect.

I"m not looking for perfection.I'm trying to make them look old and rough

hence the rasp.

I have an random orbital sander which I haven't used yet but I thought it wouldn't take enough

off.It would be great if it did.

I could buy a router and bit but it's not the effect I'm looking for.

So if you think that the random orbital sander wont wont work

is there an attatchment I can put on an angle grinder to do the job.

I see all sorts of strange attatchments on eBay.

I dunno. There's always a small block plane.

Those router bits come in very small sizes. They can also be adjusted so they just barely nick the wood. You'd get a small one and raise it up either with a plunge router or by the depth you set it. It could truly just barely touch to take off as much as you want and then you could rough it up a little with something else if you wanted.

The random orbital will be hard to control at an angle like that and you might beat the house up. I'd rather have a vibrating sander for that. This one can be raised up to take even less material off.

A router bit is really fast...

With one of these, well sharpened, you can get into the corners.

If you still insist on a power tool, you can do it with a small disc sander, you will have to change an awful lot of discs though

If you have a steady hand and a drill i find the flap wheel very useful.

Basically 20 small pieces of emery in a paddle wheel design and difference sizes.. can get right into corners and if you cant then a pink grinding bullet.....all available at diy stores

You could try a belt sander.

One of these on an angle grinder.

Wayned has the answer, but be careful if you put a 60 grit disk on it will eat the wood very quickly. You can go as high as 360 grit. They are cheep about 30 baht and under per disk depending on the grit.
