Re: Spring rigging question

This is great information in answer to the original question. (with a plan photo too!) This 8-10-D has the 'in frame' rear spring. Baldwin called it a "quarter elliptical leaf spring" even though it is actually a half or "semi elliptical spring'. The center and 'tail' portion can be rigidly mounted ...

Re: Could I get an idea on what different sized mills can hog?

Alright, guess I'll have to put holes in my desk. Maybe it will be more rigid to have a few sheets of plywood between the mill and table? When possible, I've always choked up the endmill right where the shank ends and cutting edges begin. But now that you've mentioned it's importance, what if I cho...

Re: Could I get an idea on what different sized mills can hog?

here's your first 2¢... Any bench sized mill should be bolted to a solid cabinet or stand - if for no other reason than safety. Stay away from round column mills for a couple of reasons: rigidity and the ability to raise Z without having to re-zero your work. The ability to efficiently 'hog' is rela...

Re: TESTING MORE SAFETY VALVES

To reiterate what Dave says: Why is My Valve Opening Early? A question we commonly receive is why a valve appears to open, or actuate, earlier than expected. Often, we find that the valve is not, in fact, opening early. Rather, the perception that it is actuating early is due to a misunderstanding o...

Re: Stainless steel boiler/exchanger?

No, there have been no explosions that have been reported that I know of, I was interested if there had been and the results of the failure. I realize it wouldn't be anywhere near a 'larger' boiler failure with much larger capacity than these small hobby boilers. I had read that a small boiler failu...

Re: Stainless steel boiler/exchanger?

What actually happens when one of these small boilers fails? Let's say it was a 516-70 steel boiler with, let's say poor welds that cracked. A poorly welded Ø8.25" steel boiler made with schedule 20 (.250 thick) for a 1/8th sized consolidation - (not a large locomotive). It cracked at a most vulnera...

Re: Stainless steel boiler/exchanger?

What stainless steel alloy would be best for piston rods? We're rebuilding a sorely abused Locomobile motor for the WAAAMuseum in Hood River, OR. ~R Pretty much any stainless alloy will serve, but the 300 series tends to be easy to gall, so I'd avoid them unless I had no alternative. Of all the sta...

Re: Two Silver Soldering Questions

Let me rephrase it so you can understand a bit better:

ISO tolerances and classes of fit can not be scaled. IT grades are as set out.... and you cannot scale an angle - that should be common sense.
