    Flywheels

    Thank you, Jason. Your input is very much appreciated. You're certainly right about appearance, the bigger one would look much better and I'll certainly be trying to go with it. However, I was curious about the impact of size on flywheels. And trust me, I will certainly have more silly...

    Flywheels

    Thanks, mate. The drawings call for a 100mm diameter with a width of 20mm and a thickness of 4mm. I have to admit that I'd rather the engine run smoothly at lower speeds, but I'd be willing to try a couple of different designs to see which works best.

    Flywheels

    Sorry guys, I've not been able to get online for a couple of day. All the information is very much appreciated. I'll be building Stewart Harts horizontal engine when I get a chance. Was wondering if I could get away with a small flywheel, but looks like it's going to be the full-size...

    Flywheels

    Thanks, mate. The reason for the question was two-fold, smaller diameter material is usually cheaper and easier to source and I was thinking the flywheel may have a significant impact on the smooth running of a small engine. But I may be totally off the planet with the last point.

    Flywheels

    Hi all. I've been thinking about flywheels lately and wondering what is the more important factor. Is the diameter or the mass of more importance?

    Next build

    Hi, all. I've started my next build using these documents: Bogstandard’s “Paddleduck†Engine Plans – MachinistBlog.com So far, I've got the block plate, base plate and cylinder block started, but not finished at this stage. This is going to be a slow build, lots of small parts and and...

    Elmer's plans

    Thanks deverett. I've been on that site quite a few times, but never saw that link to the appendix. Must be going blind in my old age. But thanks again.

    Elmer's plans

    I've been looking at Elmer's plans to find another project for the future. I was, however, wondering what the letters in the plans stood for, eg., these plans: http://plans-for-everything.com/downloads/steam_engines/SE%20ElmerHorizontal.pdf have capital letters in circles. It would be nice to...

    Myford S7 saddle wheel

    Nice mod. Might try something similar on the Hercus I use. The cross slide handle is a real pain.

    A Lightweight Husky

    Lovely work. Something to aspire to.

    First engine, even if it is only a wobbler.

    Nice engines, but to be honest, I prefer the look of your father's engine. Also, it would be an easier job to fabricate the base as I don't have any casting equipment, yet. Where would be a good place to start a new thread for this? I'm seriously thinking of doing a better job on logging the...

    I'd love to see your progress, bsulli81

    GreenTwin, I take it you've seen the magnetically sprung wobbler https://www.homemodelenginemachinist.com/threads/magnetically-sprung-wobbler.28961/ I'm thinking of trying that idea out on your engine, but I think I'll build another simple wobbler with one to see if it works. If so, then I'll...

    1 board foot is 2359.7372 cubic centimetres. Not sure what the metric equivalent of a bored foot would be though :)

    I enjoy filing, but it's hard on my hands, especially needle files, so I avoid it when I can. But it might be worth a go.

    Oops, I thought I hadn't posted that previous question. Sorry about that.

    First engine, even if it is only a wobbler.

    Prefer metric to those other strange numbers, lol. I'm doing a conversion to the closest metric equivalent, hopefully they'll work. I tend to use scraps for a lot of my work, especially in wood. I can dress it to any size I want, so that's not a problem. A question though, if you don't...

    GreenTwin, may I ask why the inlet and exhaust ports on that engine are the shape they are? Would they also work if they were just round?

    Very nice engine, GreenTwin. Think I might give it a go. After I redraw it in metric ;)

    Thanks, minh-thanh. I'm pretty happy with it.
