I don't have a lot of experience in compression ratios and designing engines. I did design and build a Witte hit and miss a while back and I set the compression ration at around four to one by design. The engine fired every other available available power cycle and I couldn't seem to 'fix'...

I was wondering that also Jason?

Looks really good Ken. I’m thinking you could achieve the same result using something like J B weld. It’s good to around 500 degrees F and might be easier to manage making fillets?

Great ideas and nice job Jason. I did simular to what you did on the Witte model I built a while back, except that I attached the cylinder boss (an igniter boss in my case) with small screws and sealed it with JB weld. Made the fillets with JB weld too.

Hi Ken and Jason…(Jason’s is a former acquaintance from MEM) Looks like Jason and I have your interest back. Sorry to hear about your friend; I lost one of my mentor’s last year. I have a few of his tools to remember him by so he’s still with me when I’m in the shop. Regarding age; I don’t...

Hello Ken Thanks for your timely reply. I can sympathize with having too many “irons in the fire”. I too am in the USA (Raleigh, NC) so my tooling is imperial. I spend most of my social networking time on MEM where I’ve authored several build threads, not so much time here in HMEM. I would...

Hi Ken. I haven’t seen any activity on this thread for a while; I don’t know if this project is proceeding or not. I’m also looking at the Benz motorwagen (the entire vehicle including the engine) as a possible project. I purchased the Model Engine Builder article but am disappointed in that...

Lots of good ideas,thanks. The current build is far enough along that I think I’ll “stay the course” and stick with spark ignition. I don’t know if I’ll build any more of these things or not, but if I do I may visit some of these ideas, thanks again. also, thanks for the compliments on my...

Thanks for your suggestions regarding flame ignition, but I don’t believe you comprehend the scope of the problem. At the scale I’m using, the chamber to support the flame within the valve would be about the size of a pencil eraser. I’m not saying it can’t be done, but it’s a task I just don’t...

I’ll attempt to discuss flame ignition without getting too preachy (working at a University for 25 years... I can get that way). Back before spark ignition, back before igniter ignition, back before hot-tube ignition; there was flame ignition. Flame ignition, basically, is having an open pilot...

You don’t want the piston to ‘bottom out’ on the frame during the up stroke. Several full size have been destroyed in that way. The piston upward movement is arrested by atmospheric pressure before it travels its full available distance. The combustion makes a bit of noise, but not a sharp...

Hi Richard in order not to carry this thread off track I have answered your question regarding the models in my avatar by posting a new thread in the ‘engines’ section titled ‘three Otto Langen models’.

In another thread I was asked to provide better pictures/videos of the engines in my avatar. I’ll attempt to do that with this thread. These are my three Otto Langen atmospheric Internal Combustion Engines I’ve built. The Otto Langen atmospheric engine was designed and built by Nicolaus...

I’ve had my G4003G for ten years now. It’s a good solid machine and I’ve use it a lot. I wish it had a slower low speed than 70 rpm,it can be problematic when turning large diameter (12 inch) flywheels but carbide tooling will allow it. You can even get the collet attachment for the G4003 and...
