My single cylinder engine

[borna]

Hello All,
This is a new 4 cycle 1” bore x 1.5” stroke with 5.5” cast Iron flywheel.
I'm building this engine from scratch and started this on Feb and worked on it part time from time to time. I almost done like 95% with all the parts so here is a sneak preview.

Going to be a nice looking engine. Is it based on Jan Ridder's 4 stroke design?

That is a very good question. Just searched on Jan Ridder and yes it is him .
I hope he doesn't mind
I saw an engine in youtube while back and liked the look of it a lot. So decided to make something like that. So basically it based on Jan’s engine picture but not on his specifications.

Don't think there's any harm in building an engine that looks like somebody else's. Anyway, Jan is a good natured chap and he makes his plans available at no cost, so he will probably take pleasure from the fact that somebody admires his engines enough to make one like it.

Nice work Borna, will be watching this one!

 

[borna]

Thank you all.

Ok I almost there. Good compression, no valve leak. All parts are completed. Only thing is left is the ignition stuff.
Should be able to start running it by next weekend.
Kind of big fly wheel, not sure the best way to spin it?
Does this fits the criteria for project of the month?

Hi Borna,

When you get up and going,please post video.

Well done Borna,
Beautifully made, personally I would like to have seen a cutout for the flywheel rather than overhanging the baseboard. Just my preference though.

hello Borna and congratulations on a job well done! I am wondering if the balls in the cam followers (tappets) actually rotate (like a ballpoint pen) also which method did you use to make the cams? Cheers.

Thanks all,
Graham, that is a very good idea. I think I am going to consider a cutout for the flywheel.

Stew, yes the balls are rotating freely in the tappets. For the CAM I made the blank on the lathe then finishe it on the mill with the rotary table.

That`s a very nice looking engine!

Are the cam lobes hardened? I wonder if the balls in the tappets could carve a groove in the cam... :hDe:

 

[borna]

No the cams are not harden. Do you think it needs to be?

 

[gus]

For vehicular and industrial engines ,its a must to minimise wear. For this engine which runs for short demo periods,I would imagine it does not matter. Just my "two cents worth".

 

[borna]

All done. On my way to Walmart to get Coleman fuel.

So the video should come any time soon?

Checked two walmart stores and no Coleman fuel
