check out this small engine im building!

[vwdmc16]

well i've been hard at work on the motor but it is still slow going, i've got less than 10 days of class day to finish it if i want to try to start it before im out of school. anywho, i've made some solid mounts for the cylinder to fix on to the case but it's still kind hacka and really poor fitting, oh well thats what liquid gasket is for!

i'd refine it more if i had time but i don't. for a flywheel i went back to an idea i had before, cut a thick disc of steel out of some 2" solid rod we have at the shop, i cut a few thicknesses to experiment with the flywheel wheigh, overal that will look good. the tricky part is getting the hole dead on the center, which it isn't, so yeah it's gonna vibrate bad. i still haven't decided on how to secure it to a 1/2" solid rod which is the crank size, a woodruff key, pins, threaded shaft and nuts? i don't know. also i found a perfectly sized pip for the intake moanifold to hold the cab and reed valve, that's another tricky part

well i've no pics today bu maybe on friday

cheers

Just a question (non related to any info on how to build/improve your design, sorry)... Getting this little engine of yours running before your time is out..., is that a personal goal or a requirement of your project to score points? Personally, if I was a teacher, I would give some serious credit for effort/thought/execution of idea etc. That is what it is all about no? Thinking out of the box etc.... Or am I missing the whole point of school/projects?

Either way, some may say that you are not doing anything special(by modeling it after an existing engine), but I say top job!! :agree: Keep up the good work, and maybe we can see it running, even if you run/ran out of time!????

Bet the metalshop has a lathe....
Thats the tool to use to get a hole dead center

sorry no we have no lathe, damn, my old highschool's shop did some 30yr old rusty ones but a lathe none the less.


so this isn't for extra credit or a grade at all, but i will be making a 100% in there so woo hoo. most kids build simple stuff like BBQs, the first semester, we learned the tools and showed our skills on various welds and fabrications. i was the first finshed by a month. and with the highest grades. but all we do the second 1/2 is build what ever we want and pay for the metal we use. it's pretty cool
