Any idea's on how many cu. in. it will be.

Not sure if I am up to it, but this is my latest dream. Still designing but here is the "short block". Stay tuned as thing progress....

I wish it wouldn't crash.

If it's not nailed down, it's mine.
If I can pry it loose, it's not nailed down.
Keep up the good work Eric,
It has been very enjoyable watching you build upon your ideas.
Ken
7/8" bore, 7/8" stroke. Computes to just over 1 square inch...

Starting to look like something...

How about making it a Hemi.

Nice work Eric. Looks like it'll be a nice engine.
Is the camshaft to be driven by gears, chain or toothed belt?
Keep the pictures coming! How is the design progressing, when do you intend to start machining?
Nick
The cam will be gear driven. Gears will be outside the block (no room inside). I will start machining once I feel comfortable with how everything fits (maybe a week or two). I am a beginner at Solidworks so the design is a little slow to progress, also as I go I want to make changes which adds to the problem. At least I am learning.
This design will stretch my abilities in both machining and cnc programming. I hope I am not biting off more than I can chew.
I have no idea how to draw a spring in Solidworks so forgive the lack of valve springs for now.

Woops. I have a serious interference issue with the crankshaft, con-rods hitting the block.....Crap. Hang on, big changes coming...

Been following this with interest and maybe reccomend from looking at your layout. Your oil sump(pan) I presume is what the bottom part is and for clearance you probably should go straight down the side opposite the push rods. This may give you the clearance for the rods and also the crankshaft counter weights.
Just a suggestion and keep it up.

Yeah now you've mentioned it it does look a bit offset towards the camshaft side. Nevertheless, sure it won't be too hard to sort out at this stage and it's still looking great.
Is solid works a PC based CAD package? What are the tech requirements of the PC to run it?
I could really do with some sort of 3D package, I can use Unigraphics at work but I don't really want to be at work any longer than I have to!
Nick
On another note with the clearance for the bottom end you may have to go wider at the sump/block. A lot of engines are large in that area for the same reason. Just about impossible to keep it narrow using rods with capscrews to. If you look at a model rc engine or other type(weedwacker/chainsaw) they do not have bolts on the rods. They are full circle on the bottom.
