    Wanted Bob Shores Little Angel plans

    Brian, I’ve got plans for all the smaller engines including the Kerzel and Webster. Unfortunately, I think both these engines are just too big for my Sherline equipment. I’ve ordered the metal for both the Tiny and the Little Angel from Ottawa but unfortunately it seems to be stuck somewhere in...

    Advise request for first IC engine build

    LOL, magnifying glasses and large hobby expenditures are part of my life now too. Nice to see that I’m not alone. Harry

    Advise request for first IC engine build

    Thanks for the latest comments folks! I’ll build the con rod out of 6061 since there is no way I’ll ever run the engine as much as Gail runs his. On another front, my metals order delivery has been delayed to next week by Purolator. If I didn’t have bad luck on this initiative, I’d have no luck...

    Advise request for first IC engine build

    Thanks Harvey, good to know. Gail, thanks for letting me know my materials should work. I’m just now starting to try distinguish between the various alloys and find these tips very useful. I doubt very much that I’ll put any significant hours on the engine if I do indeed get it running. I’ll...

    Advise request for first IC engine build

    My metals order shipped today so by early next week I should be the proud owner of a “Tiny” engine in the rough! There were a few items I couldn’t get but I should be able to get around most of the omissions. The 2024 aluminum for the connecting rod came in at $60Cdn for a 6” square piece so I...

    Good idea, hadn’t considered that but will consider it as a future model build. Harry

    Advise request for first IC engine build

    Thanks Gail, that information is golden! I just ordered the ball bearings and will try to source the materials you suggested. I‘ve got all the K&S music wires left over from my RC and robotics days but unfortunately the smallest is .015”. If I can’t find any locally I may take you up on your...

    Advise request for first IC engine build

    Thanks for the encouragement and advice. Gail, it was through reading many of your posts on the “Tiny” that my interest in the engine was first stoked. The crankshaft doesn’t really scare me (although perhaps it should) and I’m anxious to try to build a couple including silver soldering one...

    Advise request for first IC engine build

    I’ve completed 4 steam engines and one stirling and feel I’m ready for my first IC engine. Perhaps ready is not the quite the right word, anxious might be a better one. I own the plans, and have carefully looked them all over, the Tiny I.C. Engine by Putputman, the Upshur vertical single, the...

    Wanted Bob Shores Little Angel plans

    A member has sold me a set of plans. Looking forward to the build. Harry

    Wanted Bob Shores Little Angel plans

    I’ve built a number of steam engines on my Sherline equipment and now want to make the jump to a small IC engine. I’ve recently found out about the Little Angel plans but the folks that have taken over selling the plans don’t ship to Canada. If someone has a set they’d be willing to sell and...

    Trouble-shooting a new Stirling

    Sluggishness is not the problem; non-performance is. I had it more or less running as evidenced in the above video, when many of the parameters were less exacting than they are now. I am totally perplexed. The power piston fit seems great and if I plug the transfer hole and pull it out quickly...

    Trouble-shooting a new Stirling

    Thank-you, that’s very interesting and informative. It looks like my piston/cylinder combination is bad. I cant seem to do anything right. LOL! Right now I’m trying to understand the theory of how these engines work because my motor runs in the opposite direction that I think it should run...

    Trouble-shooting a new Stirling

    I’m giving this a rest for a while until inspiration may again strike. I can’t really imagine why it stopped running completely after I “improved” much of the engine. Here is a short video that I took when it was running for up to 30 seconds before quitting.

    Trouble-shooting a new Stirling

    I agree, compression is my nemesis. It has to be in the displacer since I also replaced the fittings that the tubing slides onto to ensure they were air tight. But O-rings are very tight and the connecting rod seats nicely in its bearing. I had taken them all apart and checked the clearance...
