I find that, even with my 36 TPI T-blades, my GST 135 BCE still doesn't leave my sheet metal as smooth as glass.

I have used several things, including a Dremel with grinding attachments, but have not gotten the result I want.

With wood, it couldn't be easier. I use my Bosch GEX 125 with 240-grit wood sandpaper, and it couldn't be smoother.

Now I just have to find something equally good for metal.

Thank you.

hi track
i used to be a sheet metal worker and the simplist way is to use a very fine file. there aint much else. ok

Agree with Colin, a coarse file to flatten the cut, then a finer file to clean it up. Used with the handle pointing as near to the line of the sheet edge.

We used to rub the file with chalk to get a smoother finish, especially on brass or ally.

Thanks guys.

Do you know where I could find a fine metal file?

Also, a crazy idea - are there metal sanding discs for my GEX 125? I love the finish I get with it on wood.

I used an oil stone to polish the edge on a sheet I was working on.

I dont see why you couldnt use a normal disc, although it would wear out quickly using it on a sheet edge.

As for fine files, any decent toolshop should have some.
Bahco are half decent, well priced, and come with the handles fitted.
