I’ve been asked several times for details of how I constructed my hood, so here goes. Click on pictures to enlarge.
This second one made for Edith (pictured before the paint job)was nearly identical to the first for Florence.
Materials: Frame – all stainless steel, hood material – mohair.
When taken off, the entire hood goes into 2 zipped bags to stow away behind the seats.
There are 2 fixing points either side on the chassis side rails. During the bare chassis stage, I welded short tubes into the chassis rails so as not to weaken the rails.
The side piece bolted to the chassis forms a socket for the uprights, spaced away from the rails to avoid crushing the body shell. Welded up from offcuts of 12 tube and 2mm sheet
The frame is made up of 12mm x 1mm wall s/s tube:
2 short vertical side struts
2 double curved side hoop assemblies
2 nearly straight centre pieces
1 long back to front piece (10mm, also used as joiners for 12 tube)
The hoop pivot pieces were welded up from scraps of 2mm & 12mm tube. A stop prevents the front hoop drooping too low.
To bend the hoops I cut out a piece of 12mm mdf to a slightly smaller radius than required for the bend, screwed this to a base board with another capping piece 10mm bigger than the radius piece. Keep the tube longer than needed, anchor one end down then pull the tube round the radius. (Not easy!)
The flattened ends were heated up cherry red then clamped in the vice (plain jaw). Needed a couple of goes.
The centre front mount relies on a bolt through the screen mount, a gap between the glass is essential if the glass is toughened. Laminated glass could be ground out to form a hole but trying to drill is a no-no.
The side front mounts are hood studs. The ones I used were plated brass so was impossible to weld/braze/solder to the stainless bracket. Any nut on the inside would have interfered with the glass fitting. So I drilled a hole, countersunk the inside with a dremmel and then run a blob of solder on the back of the stud, cutting excess off with the angle disk cutter.
