Got what I paid for

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.

After drilling about 6 rivets each they were in this state.
The rivets could be stainless steel.

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.

Stuck the print in

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!

Air ducting behind the dash

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.

This is actually going to be 3 parts glued together to reduce the complexity of the print.
The half size test pint

And then inside will split up the air flow unevenly so that the driver side has far more air flow than the passenger side.

The small top left aperture will feed the passenger side windscreen and the small lower right aperture the passenger foot well.

Greening in Surrey

Went for a trip around the Devils Punch Bowl area last weekend.

The blue green route is roughly where Google though my phone went, the darker blue route is the fast route home.

We went across Frensham Common and then through a load of other lanes around the punch bowl and lastly up Wagoners Well.

Heater blower fitted

At long last I can have hot air in the cab again. Not that it helps anyone other than the passenger at the moment as there is no dash or duct to direct the air my way or onto the windscreen for that matter. That’s the next job.

In situ
You’d barely know that I’d done the job really.
From the outside end things, minus the grill covers the hole.

Heater blower completed

Today I assembled the bits, had to re-solder the wires to the resistor, they broke off at some point. Found some new nuts and bolts, but also used old stuff where I suspected it was imperial.

Should have hot air into the cab again soon!

Black heater blower

I have painted the heater blower now, not done a great job, but it’ll do, it’s far better than it was. At least now it’s build some pressure and move some more air. Reassembly is next, re-fix the resistor to the side of the housing and re-solder the wires to the fan motor.

Nice and black.

I phoned Flag, who’s paint I used, to find out how it was going to do covering the Sika Flex brand sealant I had used to fill some of the gaps. The nice person I spoke with didn’t seem to understand the question very well, and given that the worse case seemed to be that the paint wont take to the polyurethane, I just went ahead and gave it a coat. Whats the worst that’ll happen?

Volvo Alternator

After the voltage regulator failed I purchased second hand alternator for £30. I fitted this and it turns out that it works perfectly.

One new “old” alternator.
Looks like it’s always been there..

I also swapped out the Land Rover starter motor for a new one. It’s made a hell of a difference, I think in part because the old one was rusting from the inside out because of water ingress over 9 years.

New and Old.

Blower welded and painted

I shot blasted the inside of the housing to clean it up and tacked the thing together. Ground back the rather rough welds. Stick welding thin sheet is difficult for me. In some places the sheet is so thin the shot blaster put holes in it.

Just now needs some holes filling and painting black.

Blower housing

I cut away the rusted material today and now have two of the three patches complete and ready to weld in.

Cut away the bad..
Two patches made
Just need some careful spot welds now.
