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.
