The Return of No. 83, a Hot Air Engine
vtsteam:
Well it's kind of disappointing to see the very small amount of interest most visitors to the site pay to people posting here. Other than a welcome few comments from old friends, it's as if we were alone.
Yet I'm seeing 2000 views a day on the progress of this little engine. and in the forum statistics on the front page right now, 500 visitors, and only three members signed in.
This is a rather sad state of affairs, and a forum like this will not continue unless others join, sign in, comment and, one hopes, even add interesting projects of their own. Certainly, now, I'm asking myself just who is it I want to communicate projects to? If it's just lurkers, bots, spiders and AI content reapers, then no thanks, I'd rather just work on my own.
Nope I'd rather talk with real people. Are there any out there in that group of 2000 views, or those 500 visitors today? Say something. Say hello. Say anything! Let us all who post here know that we have a reason to do so. Organic Intelligence. :mmr:

I’ve been on this forum for a very long time. I remember when forums were much more active and there was a lot of discussion. I don’t post much because I am not very active in my shed while life is busy. I also think YouTube has kind of trained us to be passive consumers of content rather than participants in discussions.
This is a very interesting project both technically and the back story. I’m really enjoying watching you problem solve and tweak this little engine. It gives me something to aspire to once I have a bit more space in my life again. For the time being though I am enjoying your build.
I’m checking in regularly.

Oh, that's great Nick! That gives me a real boost. Thank you! :beer: :beer: :beer: I hope you will build an engine (if you want) that would be great to hear about. Very happy to hear this thread means something to you. :med:
I hope people do want to communicate on fora again, I also see the lapse of the last few years, and yes, probably videos have a lot to do with it. But there is no substitute for group conversation. We're humans (mostly), we talk, and we want to be heard.
I know I'm really not writing this stuff for show, I'm here to communicate, and hear from others what they are doing and are interested in. And I really don't care at what level that is, could be expanding an ant farm. Or fixing a trumpet. Great! Bring it on! :lol:
Okay so, I've been working on a side project temporarily, trying to rehabilitate some small cnc equipment I built a long time ago, and which has been attacked by time rust and mice (TRM) in my further shed. Definite hazard around here. And trying to get my head around what to do about the disappearance of the parallel port as a viable means of CNC communication, since both of the now dead old laptops I used for that did so with the contraptions I once built.
That's beside the point of this thread, and so tonight, not to seem to have become sidetracked completely, I ran No.83 on electric power for two trials, one with displacer cylinder #3, and one with displacer cylinder #4, both at 100 watts heat exactly.
The #3 cylinder (thicker aluminum base) was slower to heat and run up to speed, but ultimately edged out the #4 cylinder at top speed by about only 10 more RPM. In both cases the rod ends were annoyingly noisy, and I really want to replace the whole set ASAP with what I hope will be a big improvement all around. I think the #3 cylinder possibly peaked at RPM because of this mechanical mayhem, rather than actually reaching potential.
BTW the CNC machines are, I hope, going to give me a lost foam casting pattern for the heat exchangers cum base plates (hollow and water filled this time) for a high speed vertical shaft Rider variation on this engine -- using otherwise the same specs sizes and construction as No 83, for comparison testing.
It will be called No 84, of course.
Well okay one more thing -- I'm trying to rehabilitate my small melting furnace, too, after it got buried in snow this winter and spoiled the lining. So, that's four projects I'm doing at the same time right now. But that's a happy state of affairs for me...disorganization is life.

From what I see it really started declining after the like button failure people need feedback even just to see if someone out there is watching.

I agree the "like" button was good to show interest even if you had nothing to add to the conversation.
