Look for Metal Supermarkets -

George King Metals - Tooting - corner of the High Street and Blackshaw Road. Can't find the actual address or phone number here at the moment. Hope I've got the street names right. The High Street is the one which follows the Northern Line, Blackshaw Road where St Georges Hospital is. About 1/2 mile west of Tooting Broadway. The next major intersection (traffic lights) you come to, just before the railway bridge.

It's an Aladdin's cave for all metal etc in small quantities. Park nearby but you'll have to pay - although they do have parking round the back, but often full and difficult to get to down a lane.

No parking round the back now. Street parking 1.80 per hour. Wandsworth, the 'brighter' borough. For their chancellor.

Ebay, there are people on there that sell Alluminium,just buy a piece and ask them to cut it to required dimensions

just type into search bar...Alluminium plate

I expect it would help if you spelled it correctly.

:o)

I expect it to work with two 'L's...and it does. :-P
