Acme Stainless is a "lolly shop", they produce a vast array of quality parts and fasteners for Matchless, Ariel, Triumph.
Check out the brake rods, and accessories; very tidy rear brake rod light switch sleeve for 1/4" rod (adjustable), and Amal carby parts, etc.
I don't need air conditioning in the shed "complex". All walls and the roof are lined with insulation, and there are whirly birds in the roof. Open up the roller doors on the north, south and / or eastern sides and the breeze does the rest. Cold winters or summer in the high 40's, I can still enjoy "High Church" in the shed.
Plus, 22 solar panels on part of the roof.
Cheers,
Richard
