The length of the hammer handle lol

nice try moofus, but the aviation snips are still up for grabs!

[ryan]

ill guess for proper weight distribution

[waltinhawaii]

Interesting theory Ryan! Nope, c'mon you greenhorns, get in a guess. It's monday and too much work to do anyway and I hate working

[ryan]

we get one guess a day right?

[liftit]

As someone who spent three years laying rail for the Alaska Railroad, I should know this.

I'm assuming you mean rails, and the reason for that width has many myths. But the reason US rails are that far apart is because England's were. Many stories about it being the standard width of carriages and chariots and whatnot, but it's mainly an arbitrary number.

[waltinhawaii]

Liftit, that's pretty much it! The number is not exactly arbitrary, but that's close enough. England built the first rails and equipment, and the US took the market over after that so we built them same way they did so the machines could be used interchangeably. England did so because the early trams were built that way. And the trams were built that way to use the same roads that Rome had initially built. The Romans used that measurement, it was said, because they needed to fit 2 horses side by side for their chariots so if you wanted to build roads of different width, you could; but the wheels would eventually break from bucking too much crud outside of the 'normal' roman road width. So, pretty much arbitrary and just a custom that was handed to folks that had too much inertia in use to make a fuss over it. In the early days I could see people following the tradition as the wheel spacing needed to follow the road widths to prevent too much breakage, but in these days, it's just too expensive to move the width as we cannot back date the equipment that has to run on them.

PM me your address, sir! the prize is yours (no big deal, just a pair of souped up scissors).

[liftit]

Haha, I honestly just wanted to answer a question about rail.

[waltinhawaii]

well, I'm progressing into the middle part of the pipe... but it's got the mounting flange welded to it; so I had to grind down the welds and chisel off the flange:







Strangely, under the rear baffle just past the dwell section (straight middle section of the pipe where it is fattest), there appeared to be a second cone inside the first at a slightly steeper angle, and it's also perforated:


it was only tacked into place by 3 heavy tack welds though: so they required grinding down and then the inner cone could be taken out, although I had to cut mine up to get the edges narrow enough to pound out from the midsection, which is slightly narrower than the perforated cone since I cut it a small distance away from the straight mid section:



midsection sides sectioned and pounded out roughly parallel, now waiting for small V scraps to be inserted so it can be welded up into a new straight section for my pipe. The technigas has a rather short dwell.

Thats an inner sound deadner,the LeoVince pipes use a similar set up,surely it messes with the pipes tuning though!

[2strokd]

Never knew TG did this as well. Thanks for sharing this.

Also explains why they are a quieter pipe in comparison.

[jonik]

Yasuni has that also.

[2strokd]

Boooo!
What Yasuni model is that?

[jonik]

C16.

[2strokd]

What a shame..
