2012 in review

The WordPress.com stats helper monkeys prepared a 2012 annual report for this blog.

Here’s an excerpt:

19,000 people fit into the new Barclays Center to see Jay-Z perform. This blog was viewed about 79,000 times in 2012. If it were a concert at the Barclays Center, it would take about 4 sold-out performances for that many people to see it.

Happy Christmas

I don’t have a suitably themed photograph, so how about this famous duet?

Vanagon – Syncro propshaft bushing – 6 month update

Today, after the latest storm blew over and rain stopped, I got under the van and pulled the propshaft. “Again?” I hear you say, yes again. This time prompted by a few things:

1. I still have the slightest bit of propshaft vibe around 55-60 kph

2: J. Slider and I have been having an email correspondence discussing measuring flange angles on shaft. I want to re-do my measurements after the exchange of ideas we had.

3. I have a jig in mind to set flange angles.

So I pulled the bugger and it will be taken to driveline guy to check balance. So seeing as I have it off, I thought I’d check how the internal Delrin bushings I made back in June are holding up (the original posts describing how I made them, part one and part two). Well, the fit of the shaft in the bushings is as tight as it was when first installed. I tried to get some pics, in one of them, you can make out the split bushing still intact at the end of the bore. I have to admit that I worried that the split bushing wouldn’t last, I’m pleased that the Delrin held up.

Vanagon – muffler update

I got the final end cap welded on today, not the neatest tig weld due to my poor cutting of that end of the can. No filler was used in the weld, just flowing the parent material. I gave the muffler a quick once over with a cup wire brush on the angle grinder. I think this is as far as I am going with the finish, I don’t see myself holding the thing up to the buffing wheel for a couple of hours.

The pics show the muffler sitting on some aluminum off cuts ( I have access to a lot of interesting shapes in various thicknesses of aluminum, remnants from water jet cutting of work parts). These scrap bits had curves to match the radius of the muffler. The scrap is clamped to a spare engine mount casting so I can see how I need to move things and what metal to remove. I’m leaning towards the aluminum supports (yes David, there will be electrolysis where the ss and Al touch:)) with some T-bolt ss straps holding the muffler tight.

Vanagon – making a muffler

As if I don’t have other things to do, I’m making a muffler for the van. I’ve had the idea for years so why not give it a go eh? Scrounged materials used:

– perforated stainless tubing for the straight through internal pipe, 2.25″ diameter, wall thickness about 3/32″

– a section of 6″ diameter stainless tubing for can, again about 3/32″ wall.

– 2″ diameter stainless tubing for in and out pipes, 3/32″ wall.

– some stainless sheet for end caps, a hair under 3/32″ thick this time.

– stainless swarf from some big ass lathe for internal packing.

I made a start yesterday, got good buddy Dave to do the TIG work, hope to have it finished in the next couple of days.
