Y'know, I'm not convinced you're not serious...

Not my area of expertise, but I recall someone suggested filling a tank up with petrol first thing in the morning when it’s coolest and you’ll get more , because of the thermal expansion that occurrs by the end of the day. Obviously hydrocarbons expend with temperature. I’m not sure how significant it is. Our temperature range especially overnight in the desert can be quite significant. I done know if the method of measurement of fuel (flow, volume, whatever) has changed significantly over the years. I expect it will have To improve accuracy.

We picked up a little CNC router for $350 off of craigslist. This was a silly part to make with it except for the exercise.
Would be great to make molds with…

No wonder all my SAE to Metric conversions don't work... I've been using the wrong kind of math!

so what's the temperature range for an underground tank ?

Depends on where you live.
I will say that well water in New England is numbingly cold straight out of the tap, and that well water in North Florida is "tepid" at best.
Petroleum tanks aren't buried as deep as a well, but the general rule applies. (Somewhere I found a 6' deep ground temp. map a few years ago, but can't find it today.) Typically the soil temp below 6' is fairly constant year 'round.

This is why it's great to have a foundation below grade in the front and grade level in the back. This allows for a walk-out basement or garage under, and it's always much warmer in winter, and cooler in summer, and some of that is passed on to the living space above.

That’s a very good point, as obviously we use depth underground as a form of thermal insulation be it housing, wine, water or fuel. Does it make any difference to the petroleum? I’ve got no idea. Though I’m sure there are petroleum and fluid engineers out there that could advise. I’m only regurgitating something I heard, which could be complete bullshit. I suppose if you’ve got fuel stored in a 44gallon drum under shade in a hot climate (like here), then it might be preferable to fill up the vehicle tank in the morning when it’s cool? Might be safer.

Pattern Makers Vise, What do you think?
Ive been thinking about getting one of these for a few years but getting them to OZ may be a challenge.
Do any of you use one, what do you think. What specific work?
There appear to be modern reproduction of the Emmett style.
my current vise has served well for 30 yrs but does lack some versatility.

Emmert. They're great for shaping stuff (Hence the term "pattern maker's) like boat parts. I find them to be bulky, and mostly in the way for doing cabinet/furniture work.

Uh, Emmert?
Whoops, a bit late.

Thanks, I appreciate what you say. My thoughts were to attach at the end of the bench so that it wasn’t in the way all the time, and use the trusted old Record Vise for most other stuff. (3” thick Jarrah planks should be sufficiently strong). My problem is sourcing the Vise here. I noticed a variety of reproduction. The Tucker veritas looks good though expensive and apparently unobtainable. The Woodcraft version though cheaper also seems unobtainable at present. Then there’s bits of Emmerts about, again in North America.

From my limited experience, the modern copies are fairly good, but lighter construction, so maybe not as strong. A real Emmert in good condition can cost as much as a decent used car.
