Model engines

That's a pretty handy material to have in the shop. I found welding rods to be the cheapest way to buy brass (or whatever the alloy is). My supply is...

'fish bellied beams'- you could emulate that with a bit of triangulation under the bottom of the beam if there's room for that. 1/4 inch deflection doesn't...

You guys have collectively answered my questions quite well, thank you. I'm glad to see there's a strong appreciation for the 'works' that people do in...

[darryl]

And you do some fine work, Sid. Art and function. The last 'engine' I built was before I left elementary school- and long lost as well. Mine was function...

[darryl]

Firstly, let me say that I appreciate all you engine builders, and the projects you come up with. My question is- and this is in no way critical of your...

[darryl]

Ha ha. Several beers in, that's how I feel- like I've had a lobotomy. Sometimes I get to the third beer, but most of the time I stop after the second...

[darryl]

I don't have much to add here, as I am not an expert on anything. But I did burn wood for heat for a lot of years, and I've had my share of 'incidents'....

[darryl]

I see that now-

Months now for it to cool down-

I have a beer in front of me as we speak- Caribou Honey. It was a cheap one, but I don't mind it. Here's to you all-...

100M40- that could be 100 amp, 400 volts rating. Or it could be 100 volts, 40 amps- which seems more reasonable. I don't see a large finned heatsink,...

I like to have some beers. Lately I've been trying out SteamWorks. One that I like is Heroica Red Ale. One of my hiking friends of the past made beer,...

[darryl]

Aostling- I did not mean to challenge your thread about this- I probably got a bit excited and forgot that you had already started a thread about JWST....

[darryl]

It will have a small elliptical orbit around L2, one of the Lagrange points about a million miles from earth. That's a point where it can set with minimal...

[darryl]

For me it probably was the replacement body for the Land Cruiser. '74 was a bad year for rust, so when the wheel wells started to rust out I took on the...

[darryl]

Deployment of the secondary mirror apparently now complete as well-...

[darryl]

I have always had considerable enthusiasm for things space- satellites, probes, etc. The recent launch of the JWST had me watching the launch before I...

[darryl]

I apologize if I sent this thread on a tangent. I am intrigued by gld's question. I was at one point going to build a 'diaphragm' engine, basically an...

[darryl]

Just to add some unwanted confusion to the mix- the act of rectifying ac and smoothing it with a filter capacitor is a mixture of high currents flowing...

[darryl]

I don't know about a model engine, but I think it was Honda that made a short stroke engine. It had oval pistons and revved like crazy. I thought that...
