DIY Replacement TLR/SLR mirrors
« on: April 30, 2011, 01:10:36 AM »
I've just replaced the mirrors on my KW Pilot Super and Pilot 6.
If anyone needs a replacement for their TLR/SLR mirror, I've posted some info on making your own over at photo.net and apug.org:

Thanks! Something I've tried a few times myself with old TLRs. Feel free to collate and add here to the Articles section as well if you like - that way people can see without having to register as well. Nice work! Skj.

Cool. Useful. Thanks.

I've tried to use the front-surface mirrors from integral polaroid cameras before but failed in the actual cutting (one nice big mirror became lots of tiny little pieces of glass). Any hints on how to cut the glass without making a pig's ear of it?

As far as I know, use a cutting wheel to score the non-mirrored surface and then putting it in a bowl and pouring some boiling water on it should cut it cleanly... just watch out for the sharp edges.

I'm not the best glass cutter in the world, and I tend to break more than I make, so I really wanted to find out the best way to cut the thin glass.
I've cut the 1mm glass before with a handtool cutter with the little wheel on the end but I started by pressing a bit hard and getting big starburst messes. I also made the mistake of going back over the line but often you get 2 lines then and the break is just wrong.

Apparently, using a scriber with a tungsten-carbide tip is the best option for thin glass. Somebody suggested dipping the tip in light oil before scoring, to get a nice clean line.
Unfortunately, the hardware guy here has never heard of a 'scriber' (I don't know what they call it in Irish!), so I've just thrown my hands in the air yet again and ordered one from ebay. I never needed to leave the house after all!

I'm going to try this on some cheap framing glass first and maybe I'll try the hot water trick, Francios.

Not being much good with the traditional glass cutter I now use a Dremel with a diamond-coated wheel. 

Dust mask obligatory, but it makes a quick, clean cut.

The dremel is definitely the only way to make complex shapes.

As for the scribe, it's simply called a glass cutting wheel...
