Hi; I can’t speak for others but I’m a self-taught hoppy machinistand building these engines have taught me lot about what I can and cannot dowith different materials and my machines. Besides it is just fun to build them and see them run. Richard

John; Give ViaCAD V8 a try. I use ViaCAD V7 Pro and I like it. You can download both V8 and V7 Pro and try them both out to see which one you like. That is what I did with V6 and V6 Pro. They also have a very good support. Richard

Bill: When you got your castings you should have got a sheet with the planes for a Gas Burner Assembly, if not let me know and I can e-mail you copy of the sheet. I got myself a cheap propane torch for the shut-off valve and a way to hook the burner to a small propane tank. It seems to take a...

As the subject line implies: this is the first run for my ¼ Scale Rider-Ericsson Hot-Air Engine and pump. You can see it at: http://www.youtube.com/watch?v=m92kvTmIHV0 I got the castings in Feb. of this year. Thy are the first set of castings that I have work with so far. I found this...

Thinks Dave; I will do the cast one and if I do not like it then I will then fabricate one. Richard

Hi Orrin; First let me say you built a great looking engine. I have wanted to build an engine from castings for a long time and after seeing yours I decided to build the Rider-Ericsson. I got the same casting set that you used and have been working on it. I also got the book (Steam and...

I have the 7X12” mini-lathe and X2 mini-mill sold by Cummings. Thy are basically the same lathe and mill. It looks too me that the lathe and mill from LittleMachineShop may be much better then the ones I have. 1. Thy both have a more powerful motor. 2. The mill has a larger table (that’s about...

Try www.mcmaster.com Just type in taps, thy have a M4.5X75mm for $6.06. I buy from them all the time. Richard

What’s in a name? The engine could have been call a beam or a yoke engine. The Stirling Engine was invented around 1816 by Robert Stirling (a Scottish Minister) and the way the beam sets on the rocker support to me it represents a yoke more then just a beam hents the name Stirling Scotch Yoke...

Bogs; The one that inspired me to build this one was called a Scotch Yoke so that’s where the name came from. Richard

Just an update to let you know that I have uploaded the planes for my Stirling Scotch Yoke Engine. Hope one of you builds it. When it is done it is a very good runner. Look over the planes and let me know if you see any mistakes. Richard

Sam , Arv & Kel; Thanks for your comments. The drawings are not available at this time. I’m redoing them and will post them when I have them. It may be some time before thy are done, I’m using a new CAD program and I’m still in the learning stage. Will get them as soon as I can. The fly wheel...

Here it is finally! Some of you may recall me saying how I had lost all of my drawings that I had done on an engine that I was doing in TurboCAD. The engine is now done and here is some Pix.s of it. There is a Video of it running on you tube...

The new mill finally arrived. On July 1 the locale freight company delivered my new G0619 Mill, only five days later then thy said thy would but it finally got here. So far I’m imprested with what I see. Got 99% of the Red grease off of it (thy must get a real good deal on Red grease) thy...

This is for those interested in drawing gears in a CAD program. Check this out. www.cartertools.com/involute.html Here are two Pix. Of a gear that I did using the directions found here. Richard

Hi Bob; Just a quick note to say thank you for the information on the mill. After down loading and looking at the manual for the G0705 mill I see what you mean about the head moving off the X,Y setting when you raze and lower it (not good). Went ahead and ordered the G0619, a stand and the...

Bob, When you say moving he column up and down it disturbs the setup, do you mean it changes the X-Y position or what? Richard
