Happy Canada Day!
I decided to use part of my holiday to play around with trying to get a shine on the aluminum window frames of our Biggar
. I experimented on the inside of the window frame that won't be visible once installed.
You can see in the attached picture that I got a bit of a shine going, but not as nice as I wanted. It also was more labour intensive than I had thought.
This is what I did:
used - sewn sisal buffing wheel on 1/2HP bench grinder with brown polishing compound
results - didn't even get through the oxidation (if that's what it is)
used - medium sanding drum on dremel then sewn sisal with brown compound
results - bumpy lumpy look, almost like hammered metal
used - 220 grit sand paper then sewn sisal wheel with brown compound followed by a loose cotton wheel with white compound
results - see attached picture
I think I need a step between the 220 grit and brown compound. Perhaps 600 grit sand paper... BUT here's the thing... I was hoping there was some way to do this all by using the buffer and not hand sanding every millimeter of the window frames.
The profile of the piece I was working on is like a simple 'S' (see other attached photo). I can't get into all these tight corners well enough with sandpaper, so that is another reason I was hoping a wheel would work. (Besides, my bad arm won't allow that much elbow grease without serious consequences!)
Does anyone have some previous experience or suggestions?
(For the record, I checked out Ian Giles' site and watched the video on polishing his aluminum hinges. He mentioned more info to come on how he polished the jalousie window, but I didn't find any.)
