Working on the windscreen wiper installation. The drive needs to go through the firewall from the top of the LH footbox, so need to clad that section of the firewall with insulating sheet and 1.2mm thick stainless steel sheet.
I need some (grommetted) 25mm dia. holes in the firewall for temp gauge senders (2),
oil pressure gauge tubing and also electricals.
First attempt at drilling the SS sheet didn't work, so then tried a 25mm dia ceramic tipped trepanning tool. That worked a lot better than I'd thought, so then had to fix the already botched first hole. Used my very trusty jigsaw to take the hole out to the 25mm markup. That worked better than expected as well, so now just have to tidy up that hole. Then I'm ready to do a trial install, then cut the holes in the aluminium alloy firewall and estimate where the hole for the windscreen wiper hole goes and cut that one out too. Not a lot of fun today, but should have that part of the firewall sorted soon.
Here's what the SS sheet looks like at the moment. It
will look better when finished.
Cheers,
Glen
