I went to the MMEE in 2023.  So disappointed was I in what was in the show as a whole that I spent very little time there.  It is a long way to drive from Yeovil and back, in a day, the visit HAS to be worthwhile for me to do it again, and on last years evidence worthwhile is totally lacking

I left after about two hours, vowing never to return.  One of the (several) reasons was the lack of IC engines and their constructors standing behind them to talk to, the issue Mike (Vixen) is trying to address here. 

It was mainly just steam locos on display and fine as they are, and I do admire the workmanship that goes into them, I wanted more than just steam locos to view.

I have no engines to exhibit, but should the likes of Mike, Jo, Jason, and others of a like mind, be there exhibiting, I might well reconsider going - if only just to view their models close up and talk to them.

Good luck Mike, I hope your plan succeeds.

Great animations 

I believe that my Alibre is same vintage - but it runs on Windows 10 now. This requires you to get support from Alibre to make it work though - glad they didn't make any fuss about it.

Per   

Gerrit I know about Feature-Creep all too well 

Resonance and curing it with a change in Feed-Speed makes sence - nice to hear that it was so easy for you to fix 

Again thank you for sharing

I am using a vary old version of Alibre' 2011 with a free license for non-commercial use, running on an HP 32 bit laptop under Windows 7. I find it easy to use and extremely powerful for a 12 year old free package.  I have refused to upgrade the OS for fear of compatibility issues.  It is fun but it lacks many features of later features.  For example, it has no gear or pulley functions.  in fact, the only means to transmit movement is through cams or levers and no means to set continuous or cyclic motion.  It has no means to provide stop limits or to recognize contact nor does it have a means to define force or direction.  BUT all assembly fits are perfect, no wobbly shafts even if the bearing is oversize or missing.


Therefor, i can't simulate a release mechanism based on a knock off cam or dashpots that work. Maybe I could with a little fancy editing but...... it's what I got. It is really helpful in working out the complicated geometry of the Corliss valve linkage and testing various options. In this assembly, there are over 100 parts and about 250 positional parameters.


This post is getting too long and its getting late.  more tommorow maybe..

I am probably mixing 10:1 isoprop vs oil. To be honest the main goal is to clear chips with the air blast, esp. in aluminum.

One excellent feature of the code is that setting the flow rate pot to zero you can push one of the buttons to reverse the pump and empty the hose of fluid.
