It has been sitting for six month. The fuel pump was almost dead and I ripped out the wideband lambda to analyse the car of a friend. A storm put water through the tilted sunroof and I forgot to turn off the interior light after soaking up the water thus emptying the battery. Today I jacked it up, threw in a new fuel pump and the recharged battery. Turned on and off the ignition a couple of times to create fuel pressure in the empty lines (changing the pump got kinda messy). And what happened? The thing just started up and purred along. I LOVE these old mercs. I just had to add some fuel, air up the tires and it performed flawlessly on an extended test drive including a stretch of autobahn.
jacked up and secured with a three legged stand
Parking lot after six month. Quite grimy and some grass growing. And still leftovers from new years fireworks…
My favourite german race driver actually starts to co-host my favourite british motor television show. And she keeps on dominating the main host. Around 10 years ago jeremy clarkson (old host) did a 9:59 in an Jaguar S-Type on her home turf (Nordschleife) and she was caught on camera saying “I could do this time in a van”. Long story short: She did a 10:08 in a ford transit, no modifications and on a public driving day on the track. Look it up on youtube, fun to see a white panelvan overtaking fancy racecars and even motorcycles.
While filming the new season the new host Chris Evans jumped out of the car to vomit after a couple of minutes with her in an Audi R8 on a closed track. The new season might be fun…
I’ll still miss Clarkson, Hammond and May…
Well, my mood is still rapidly changing between happy and terrified. I a did buy a boat. The idea was to get something as small as bearable for a summer trip, slow and safe, easy to handle. Then start in a place which is great for beginners, easy waters, no tides, Kiel for example. And how did it play out? Yeah, well. I bought an 9,3 meter heavy displacement offshore racer-cruiser. The thing dominated races back in the 70s. And I bought it in Hamburg, famous for having the third largest port in whole Europe. And about 4m of tidal range. So there is all kind of weird current phenomena going on and container vessels and ferries produce large waves.
On the upside, the vessel is known for being pretty bulletproof and easy to single-hand. And she is a beauty!
Designed by famous sparkman and stephens (S&S). Build by IW-Varvet in 1970 on the island of Orust, Sweden. A modern (at the time) US Design build by shipwrights whose lineage goes back to the vikings. Literally! Technical details: http://sailboatdata.com/viewrecord.asp?class_id=5505
The last couple of days were spent mostly working on the boat or planning on what to change. She is old and battered but she wears her scars with pride.
Disclaimer: I don’t believe in the myth that all ships are female, if they have a gender at all. Her current name is Baldur but the pronoun she fells more appropriate then “he” or “it” or the singular “they”. I guess there is some nonbinary genderqueer thing going on. I’m pretty sure she’s got balls as well. And in GB she was actually marketed as the “SHE-31” (South Hants Engineering being the name of the shipyard)
Searching for some unpublished posts I found these pictures.
Old leaf springs, old shock absorbers ,hole in the front spring mount
The old leaf spring is so worn out that it bends upwards an somebody removed the wedges on the axle which adjust the castor (tilt angle of the axis which leads the steering assembly to go automatically back to “straight forward” if you loosen your grip on the wheel.
Bigger shocks, three layer spring (the hole was fixed soon after as well)
The new assembly gives a couple of centimeters more ground clearance, yay
Friends pointed out to me that they don’t understand my writings about building/optimizing speakers and don’t even know what to google for. Sorry, guys, I was just writing down what I was doing and not thinking about that.
The Variables (Fs, fb, ….) are so called Thiele-Small Parameters, named after two aussie guys doing research on the matter. Wikipedia provides links to sites explaining the stuff in both german and english.
Don’t let the math scare you away, you don’t need it. To build a woofer you just have to look up these values and put them in some online calculator which is spewing out build dimensions. Just make sure to get a second opinion on the results, be it through research, online forums or just asking folks…
