torsion bar valve springs

When I’m running, I get lots of weird ideas. Today, I thought, why not use torsion bars for valve springs in engines, instead of the usual coil spring? Benefits should include- less moving mass, adjustable pre-load, and… well that’s all.

So, this falls into the “new-old” ideas category – apparently was done as far back as the 50’s- even this clunker had them –

And some F1 cars and bikes have used them with good effect. So, good new-old idea 😉

If you can read this…

Site is moved over to new server, and running on orchard 1.0 now.

Porting was a bit painful – i used the orchard blogml module to export posts from the old server, and then import to this new one. Worked great, except that tags were mangled up. After tinkering a bit, i just dozed through and fixed the tags on all the posts. Fortunately not that many to fix.

So now to see what all orchard 1.0 can do.
