I blew a fuse in the Land Rover, entirely my fault. A terminal broke off the back of the voltage regulator, so I replaced the feed to the instrument cluster by running a cable from my 12V stabilised power supply to the instruments instead. Unfortunately, this was all I did. I lift the existing supply cable behind the dash, still with broken terminal protruding from the insulated crimp. I imagine that this had touched something that was grounded/earthed and shorted out, blowing the fuse. At least I hope this is why the fuse blew. Interesting how the wire has melted back where I guess it arced across the gap as the gap formed. Also interesting how it burned a line into the paper.
Finally I have all of the air duct in. I have not yet sorted the air into cabin, and I think I will likely need to get the two printed parts re-printed, I will alter the right hand part to have an angle on the cabin discharge port. The left hand one needs a lot of work..
I purchased some drill bits from Ebay, very cheap ones, but it said that they were cobalt so I thought I’d give them a try for 2 and a bit quid. In fairness the drills did have HSS stamped on them, but I suspect that stands for “Highly Soft Steel” in this instance, they’re almost certainly made from Chinesium. In future I’ll pay reasonable money to a reputable shop for decent drill bits. Lesson learned.
Today I have Sikaflex’d in the 3D printed “heart valve” component. There is a bit of a gap at the bottom and given that both the base of the print and the bulk head are a little convex the two don’t fit together very well. Luckily I have plenty of Sikaflex and no fear of using it!
I have designed and a friend is printing for me some components for the air duct work that supplies hot air to the windscreen and cabin of the Land Rover. And then inside will split up the air flow unevenly so that the driver side has far more air flow than the passenger side.
Went for a trip around the Devils Punch Bowl area last weekend. We went across Frensham Common and then through a load of other lanes around the punch bowl and lastly up Wagoners Well.
