Jan Ridders 2 stroke completed and running!
« on: August 02, 2017, 05:39:17 PM »
I have finally completed my latest engine project. This is a Jan Ridders "Debbie" 2 stroke (Excellent plans, by the way!)
I learned a lot about metric conversions and tank soldering. This was an interesting build. It took me almost 3 years to complete this (things have been very busy at work and home)

That's a beauty Scott, and what a nice runner it is too!!! Being a 2 stroke, does it tend to heat up faster?

Nicely done! A lot of similar elements in the glass cylinder Jan Ridders that I am building.

 I also started it 3 years ago, I expect it to be finished by year end.

Well done, it's a nice slow running engine for a 2 stroke

:ThumbsUp: :ThumbsUp: :ThumbsUp: :ThumbsUp: :ThumbsUp: :ThumbsUp:

Nice engine Scott.  Are you going to show it at Rough & Tumble in the next few weeks?

I will be at the Rough and Tumble show on the 18th and 19th with this engine and more.
Thanks, everyone for your compliments-it's always a good day when an engine finally fires up and runs!
And, yes it does get hot pretty fast. I'm trying to limit the run times, but it sounds so good........

Very nice, and agree the sound is pretty neat.  Now you just need to wrap a belt on that pulley, and tool around on an old cruiser bike... :)

Drat. I'll be out of town. Something about the loss of daylight.

Nice engine Scott!  :ThumbsUp:

is there room between the tank and the cylinder to put a fan, that may alter the time it takes to get hot, with the extra work it might get hotter sooner.

Thanks, everyone for your kind words.
I will give you an update on this engine. It has been a bit of a struggle to keep it running reliably. I had to make 4 pistons before I got a tight enough fit to keep good compression. I thought I could machine them to a less than .0005 clearance to the cylinder. I have been a machinist for a long time and I am used to tight tolerances, however my 1943 South Bend apparently wasn't up to the task. I had 3 that sealed pretty well, but they wore rapidly due to very slight tapering of the piston.
Eventually I read the instructions (!) and made a piston .001 oversize and lapped it in to the cylinder with ultra fine diamond lapping compound.
It was so tight at first that it would run for a couple of minutes and seize up. After running it for a while it has loosened up just enough to run well and reliably. I do run my engines all day long at the shows and it has performed well.
I also had to do a lot of experimentation with the fuel mixture. I found that straight Coleman (lantern) fuel would cause it to squeak and slow down due to lack of lubrication. I started adding some 2 stroke oil 1 drop at a time until I got the right ratio to keep it running well. I also added a little bit of WD-40 to keep it from sludging up from the oil. <a href="https://www.youtube.com/watch?v=0SkmM1ZrvNg" target="_blank">http://www.youtube.com/watch?v=0SkmM1ZrvNg</a>
I wanted to pass this information on to anyone else who is having trouble getting their IC engines to run well. It does take some time and patience to work through these problems, but the satisfaction of a good running miniature IC engine is worth it!
