Bowling lane wood: hoard it or pass it along?

WAY OT - sudoku
The best manual machinist I've ever met is barely fluent in number manipulation. Because he's aware of this, he checks, rechecks and never make a mistake. Me, who thinks he can fling numbers in his head, often has more trouble with a setup than he does. jack vines -

Motor rpm vs weight and size
Back in the day, when Craftsman and Delta sold motors separately from the table saw, band saw, drill press, shaper, lathe, et al, their 1725 and 3450 RPM motor of the same horsepower were the same size and weight. jack vines -

Heat treating a crossbow limb
Agree. I grew up on a farm, raised calves, pigs and chickens for dinner. If you can't look it in the eye and cut its throat, you shouldn't be eating meat. jack vines -

Getting set up for Horizontal/Line Boring
In a technical discussion, terminology is essential. Line boring Line honing Horizontal boring How are the parts being made at present? By whom? By what process? On what machines? jack vines -

tips for setting chevy head up on mill to cut guides?
Bill has been an inspiration to us all for decades, however used head shop machines, with the necessary tooling, are so thick on the ground, building one's own is not cost-effective if one could be making more money doing something else. Then, there's shop floor space. I know a Brit who builds... -

Line Boring drive
What type parts will you be line boring? If I were building one from scratch, I would go out back and drag in the Tobin Arp table sitting out in the weeds and try to buy the arms and drive mechanism. jack vines -

Maybe getting out of machining...
Yes, No, Maybe. Random thoughts for you. If you're not the lead dog, the view never changes. Beware the Jane Fonda Fallacy, just because it's bad where you are doesnt mean it's better up north. Also, the group leader over there might be as bad or worse than the one you have now. That those... -

O/T- engine guys, help me understand this leaking gasket.
As suspected, that's a big dog. They often have problems with crankcase pressure if used on road courses or sustained high RPM, such as Silver State. Most use a sealed system with a vacuum pump into a NASCAR style breather. A leakdown test is always informative. jack vines -

O/T- engine guys, help me understand this leaking gasket.
Most likely blow-by crankcase pressure. Even with good ring seal, those huge pistons moving in that confined space effectively creates internal pressure. With a rocker cover spacer, it's likely a modified engine; what is the bore/stroke/displacement? jack vines -

OT- Favorite pistols to shoot
Agree on most of the above. Just plinking on the range, it's Thompson Contender all the way. One of the things which amaze me is how much importance some here and in the general auto gun world put on it being a double stack magazine.

Tobin Arp PM 2500 rod boring machine,
For those who've never seen one, the Tobin Arp rod boring machine is maybe the most precisely, most robustly built, most versatile manual machine in the automotive shop. It bores connecting rod big ends, small ends, piston pin bores, et al, and does it to tenths. We've rebuilt a couple of... -

Why do you use cast iron vs cheap mild steel?
The Liberty's purpose was American mass production of standard units when the U.S. entered World War I. Co-designed in a week in mid-1917 by Jesse Vincent of Packard Motor Car and Elbert Hall of Hall-Scott Motor Car, with a planned series of 4-, 6-, 8-, and 12-cylinder models, Fifteen L-8... -

Why do you use cast iron vs cheap mild steel?
The eight cylinder Liberty was a failed experiment. Fewer than ten test engines were built and only a couple installed in aircraft. There was little benefit over the twelve, so the eight never went into production. jack vines -

Why do you use cast iron vs cheap mild steel?
The 300 SLR has two four-cylinder banks made of silumin with chromium-coated aluminium cylinder sleeves; the heads are cast together with the cylinder banks (i. e. block and head are a single cast piece) The production 300 SL used the same cast iron block as the 300 sedan. The Liberty V12 did... -

Why do you use cast iron vs cheap mild steel?
Wrong on all counts. I've been building engines for sixty years and had a stint in a steel foundry and have never seen a steel engine block. Bad idea for reasons of much higher cost, doesn't flow into small sections, machinability, oil retention, friction, et al. Bottom line - a finish...
