It's the amazing invisible engine!!! ;D
Works first time, every time!!! :big:

I think you forgot to post the picture/video of the engine in the excitement of getting it running!
I have done this before too....forgot to post a pic of what i was talking about!

We will wait to see your creation!!!

Congratulations by the way!!!!!!!!

I am very pleased with the way she runs,(after running her in using a belt round the chuck of the lathe) that I am willing to do plans and a build log if any one is interested?

ken
 
Very nice first engine. Any information on the build would be appreciated.
 
hi,

here is the plan of the piston, anyone who wishes to improve on it is quite OK by me (those with cad experience)

I then faced the piston head with a very sharp tool taking very fine cuts.

Next we set the calipers to 0.8125"

then mark the crank pin hole position,

set up the vee block using parallels,

then set the round stock for center drilling using the centering tool or the pointer and rule method,

using the pin method for locating the scribed line position,

the Gib strips are locked,

the hole center drilled and then drilled with a 1.7 mm drill.

that is all for today, next the input & exhaust pipes tomorrow,

Congratulations Ken! I still remember the thrill of my first engine running. What a good memory.
You picked a good design for your first one. Well done. Thm: Nothing will stop you now!

Monday tomorrow (washing day) hopfully base and upright, but we will have to see how much time there is,

see you soon,

ken
 
hi all,

a day late but here is the base and the upright, I marked the metal using a permanent marker and a scribe, I then set it up in the table drill x,y table, and used the pin method, followed by using a center drill to mark the hole positions, followed by the appropriate drill.
where the hole was to be taped, after drilling with the correct tapping drill I swapped the drill for the tap and tapped by hand using the table drill to keep it all in line.

I hope this all makes sense, if not please ask for clarification.

hopefully the flywheel tomorrow.

ken.
 
hi all,

the plan for the flywheel is not finished yet, (went shopping for bits) but I have a picture or two.

ken.

hi all,

parting off the flywheel, that will be the job for today, (notice two flywheels at once).

now to buy a power hacksaw?

ken.
 
hi all,

sorry about the delay but I had one of those days,

its called break your only 1.6 mm drill and let it be jammed below the surface in the piece you have been working on.

I managed to remove it in the end (hammer 1.6 mm drift and a 1/2 ton press).

I wonder if it would have been better to scrap the part and make a new one, but I love a challenge.

tomorrow is searching for a shop that knows what a 1.6 mm hss drill is,

see you soon,

ken.
 
I hate small drill bits, the smaller the bit the more pecking to do. At least it came out.
