Stan, I'm finding very much the same things you are but here my thoughts: I found that if I left some dead space at the top of the cylinder performance was enhanced significantly but there is the possiblity that with such low specific power any deviation in bore roundness or in the lapping of...

There are a few of us here in the same boat, it seems that once you have a little experience as a youngster this machining bug incubates and niggles away at you until you just HAVE to make some chips again. Looking forward to seeing your workshop come to life! David

Great first post Stuart!! Love the "bark" of that engine!! David

SWMBO has just signed the treaty of Leamington after long negotations and great personal cost. I'll be there most of the day, are we still meeting at 12:30? David

Join the club Stan, I'm in the same situation but there is one thing that has helped me gain some repeatability. When the hot end is heated in a lamina engine the overall pressure in the cylinder increases, sometimes to a point where the piston stops at TDC, you then need to wait until the...

No really Nick, the experimental version was almost offensive, even my 7 year old boy laughed at it, I couldn't take the shame!!! David

Excellent point Rick, My last shot must have been 18+ years ago, gonna get booked in to get one while business is slack. David

I'm just about ready now to start making a presentable vertical lamina engine, I've done all the testng I can and now have a running, if embarassingly ugly and very tempremental, test engine. No pictures, it's just too ugly :o. It will probably look quite similar to the one posted earlier in...

Ah I see last year the show was also the National hat wearers convention too :big: Seriously though, you both quite rightly look proud as peacocks of your display, great picture.. David

Reminds me of those boys in thier 1.1 litre Citroen Saxo's (compacts for our friends in the U.S) with 8" exhaust tail pipes! ;D Kind of suits this little one though, it's looking great. David

Well I'm hoping that the blades last a very long time that way it wont be such a hit when replacing them. On Ralph's recommendation I took a quick "sunday drive" to my nearest Aldi and pocketed myself one of these, I must say after the few cuts I have just done with it I'm over the moon, what a...

Much kudos Ian, I apologise for my response to your post also, we really must learn to calm down ;D It's so easy to read/see something and make an immediate and possibly ill judged response in real life not to mention here where the subtleties of a well meaning post can be easily missed.. It's...

Hi Ralph, just replied to your PM. What are the specs for the unit? Would you say it is a fair replacement for a powered hacksaw/bandsaw, it looks a bit more compact which is always nice?

Or perhaps a thread on the importance of diplomacy when trying to get your point accross? Is there an ignore button on this forum?

Hey Scott, welcome to THE best place for people of our persuasion to "chillax", don't forget to post numerous progress reports on your projects . David

The wife just suggested I make a run of these for christmas presents after seeing the vid.

Enough for 1 Aussie bbq bob? ;) David

Looks like super work to me, what was it going to be used for or was it just a "because I can" project (the best kind). David

What a great idea...will pick one of those up today. David

No input on the mount question but as an aside: This phenomena only occurs with CRT displays as the electrons that are fired at the phosphor coating on the screen are "steered" with an electrical/magnetic field, the presence of a magnet interferes with that. Modern CRTs are not damaged EASILY...
