Re: Timing belts
Unfortunately, designing a reliable timing belt drive is not a simple engineering exercise. In another life, I did such design work and can attest that there are quite a few variables to be considered. Also, timing belts are best used in moderate torque, elevated RPM situations. Low RPM and high ...

Re: Drilling holes in brass, should I pilot hole?
Here is an image of a twist drill dulled for cutting brass/copper alloys. I use a diamond file to carefully dull both edges. The drill might squeal some during cutting, but I know it is drilling correctly. I don’t do much work with brass, but when I drill it, I usually use a little WD-40 to get rid...

Re: I am a human electric cell
I have never licked anything that is electrically energized. I value my taste buds. They are some of the few parts of my aged body that are still functional.

Re: Boiler welding advice.
I understand MIG is not an option. The problem is not in the process. A skilled weldor can produce sound welds on pressure vessels using almost any process. Properly-made welds using the GMAW (MIG) process are as strong as welds produced by other processes. Note that most ASME-rated air compresso...

Re: International Brotherhood of Livesteamers site - wheels and common components
I am opposed to using Github for this sort of thing. Github is a confusing mess and I can never find anything on it.

Re: Must be bad weather ouitside
The “atomic” clock in our family area says it’s -11° F right now, and it’s 11:07 PM as I write this. Supposedly, temps will go down at least another five degrees before the night is over. Cold weather didn’t used to bother me...until I got old.

Re: Sad
Not unexpected. The average American blue-collar worker has priced himself out of the market. We are seeing a sped-up version of this right now in the fast-food industry in California.

Re: Propane firing
I have a Railroad Supply 4-4-0 that’s set up for propane. I have a stock car to hold the propane tanks but it’s not tall enough to hold a 20 lb tank. I was thinking of using four 3 lb vertical tanks as they would fit and daisy chaining them together. I was wondering how much propane an engine this ...
