Elmers #25, my first engine project
spuddevans:
Thanks Darren, I was threading, or should I say, trying to thread at a very slow speed, but I think combined with the slightly blunt Hss toolbit was the fact the 303 was only 2.9mm diameter and was deflecting away and above the cutter, and that was with only 8mm of the 303 protruding from the chuck.
I bring my Dslr out to the workshop and hide it under some clean rags and bring it out when I remember. My other hobby is photography so it's nice to combine both hobbies.
Thanks Eric, I was wondering whether when I finished the build and 1st applied the air I would only get a hissssss :bugeye: and no movement. Hopefully that won't happen.

Ha the good old pop test, thats a good sign :thumbup: I'm sure it will be fine.
The bad guy with these little engines is Mr Friction, you can have things too tight.
Nice work

Ok Tim, we got the satisfying "pop" so that means a pretty darn good fit. :thumbup:
Now, I went back and looked at your cylinder with the pivot in it. Are you going to forget to drill the entery hole for the air into the cylinder? :poke: Just wondering. :)
Nice job so far by the way. It took me several tries to get the piston right to make a good sounding "POP".

Nice looking parts collection you got going there Tim :thumbup:
As Darren said "nice clear pictures" I know you said about the DSLR, But have you got very good lighting in there too? They are very bright and unshadowed!
I like this thread..... Reminds me a bit of my first engine thread way back when (all of a year ago !! :)) it feels good to make these little things and have them run for the first time...... You wait, it's a great feeling :D
Ralph.
