Hi Sackett and wEc1
Also wEc1to you Rob (bladehunter).. Mate I have 2 questions to ask you after I try and cover Sacketts question first. Then will keep them as brief as possible. If you are who I think you are, you will likely find this interesting and maybe useful also.
Sackett,
As this is a 'model' engine forum I am guessing you meant 3 x 5 inches, not feet.
One good source of plans is the late, Mr Elmer Verburg who has kindly allowed his own collection of plans to be released free to the public for not for profit, personal use purposes. The plans can be downloaded for free in pdf format from John Tomlisons site. There are about 50 or so different types of engine, from quite easy and simple to more complex and challenging. Johns site has many other types of hobby interests as well so you may also find that of interest too. My suggestion is to read through a few plans that interest you and try find one you do not have to buy additional tooling or materials to complete and feel comfortable to start and confident you can build. Get stuck, then there are people and likely already threads with info, here to help.
If you were wanting to make a 3 x 5 foot engine you could always upscale the plans simply by multiplying all the dimensions by 5,6,10 or whatever, to enlarge to a scale that suits. Before committing to an up scaled plan, make sure you can fit/clamp/chuck and machine the parts. The flywheel is usually the limiting factor with up scaling and don't have a clue why I added that
Here is the link to Johns site.

3' x 5' Elmer engine
I have never seen one that big. I say go for it;D
Both you get ready for the addiction which is model engineering, while being rewarding, carries many afflictions, often to the wallet:wall:
However as you both probably know there is quite often money to be saved by simply thinking outside the box. That's where this site helps lots.
Okay Rob,
Question number 1 is are you from SA?
Question 2. Do you have quite a few videos uploaded on uTube?
If your answer is yes to both, I can then comfortably presume that we have spoken on the tube before regarding aluminium foundry work, furnace/burner design and casting moulds for slabs and slugs.
If that is you,
and its good to finally see you here and about bloody time!;D
Welcome again guys and
Cheers *beer*

*Rob, Just noticed the user location is not visible when replying via a email link and reviewing the previous posts in reply mode. Just noticed your profile says Sydney, NSW not SA.
Unless me thinking or falsely remembering SA, or Sydney is a typo or something, I may have made a mistake.
