full size gas engine

[chuck foster]

i don't know if this is the right place to post this project but here it go's

i have been working on this hit and miss engine for the last few weeks and here is were i'am as of today.


this morning i started by making new cylinder head nuts
heres the old ones


and heres the new ones


the next part to fix was the cam gear shaft, it also holds the lock off arm. as you can see it was worn very badly


the cam gear shaft is finished but i didn't take a picture of it 

this next picture shows the shaft in place with the cam gear and lock off lever in place. the cam gear shaft is the unpainted piece in the middle of the picture.


the last piece to be done was the exhaust rocker arm pivot pin


i made the new one to my own design. it has a oil hole right down the center


well thats it for now, if this is not the right thing to be posting here just let me know and i will stop this thread.

Chuck,

This is the sort of thing that should be posted here.

Anything that is of general interest to the members, and your post is spot on.


Plenty of pics and a compulsary vid at the end.

I'm a sucker for stationary engines, this one's looking good

Chuck,

It's the right place. 

That con rod looks a little bent. Is it or is it my imagination? 

Bernd

[chuck foster]

bernd......................it's bent 
i think i will put it in the press at work tomorrow and see if i can't make it straight again.
it only has to be moved about 3/16" so we will see.........might have to heat it as well.

Hi Chuck     (must have missed your intro? .... I'm missing a lot recently, very busy this time of year!)

That looks like fun, heavy, but fun    (I'm figuring the scale from it's surroundings.... Flywheels about 12"ish  dia?)


I too saw the bent rod, but was much more puzzled by the way the piston seems to have dissolved through the bench? 


Am I missing something here?


Is that a fold out handle for the starting ?




Anyway.... I like it!

ralph you are right it is heavy but it is fun  .

this summer marks my 30th year of playing with full size gas engines. i have had about 80 engines ranging from 1/2 hp to 12 h.p.

the flywheels are 16" in diameter and the bore and stroke are 3 1/2" x 5" and you are right about the fold out handle.

i didn't get much done tonight as we had dinner guests and for some reason they done seem to like working and eating in the shop

I went back and had a look. It does look a bit odd doesn't. I think it's Photoshoped. Notice almost no shadows under the piston? 

Are you telling or showing us "porkies" Chuck? 

Bernd

[chuck foster]

well guys the picture is just the way i took it......................what the heck is photoshop????

there is no shadows because i'm such a good photographer

Hi gang

I believe that aermotor8 must be a good photographer like he says. When he took that picture he fired the flash in an automatic setting. His shutter speed was 1/60th of a second and his camera was a Canon Powershot SX10 IS. I don't think photoshop is quite up to those specs yet.

That piston is very decieving but if you look at it long enough it begins to make sense.

aermotor8, nice job on the engine to date. Nothing that a little TLC can't fix.

Cheers

It's a program used to enhanse pictures. You can take two pictures or parts of pictures. Then add them to another picture. Inother words a picture can tell 1000 lies.   

I'm sure you get the drift. It's just such a clear picture it makes the piston look like you added with a photo altering program.

Bernd

[chuck foster]

don you are right on about my camera.............how did you know?? 

in all honesty i'm just a point and shoot kind of photographer, and if it don't look good the first time i just shoot it again.

bernd: no fancy programs here, i'm lucky to be able to surf the net and check my emails without screwing some thing up.

Still looks like it's melted through the bench   



And..... Yeah Don!  How did you know that stuff? can you tell that about my photo's?

 I use a program called Ifranview to view all my pictures. It is a freeware program and I have found it extreemly nice. When looking at a picture you click on "information" and all of the information is available. That is how I know about the information for your picture.

I don't want to hijack your thread so I am going to start a new thread with more information on this program and photo editing. I have done a cut and paste of all the information that was in your picture here and posted it over there. Here is the link to that thread. http://madmodder.net/index.php?topic=1710.0

Chuck, as a long time acquaintance of gas engines I presume you have a lot of experience with hit-n-miss.

When I was a young lad we used to shear hundreds of sheep a day using a 'Coopers Little Wonder' sheep shearing plant which was powered by a hit-n-miss which if I am not mistaken was made by 'Glover'.  It was a very conventional engine of about 3HP.

With two people working the engine was at its limits and hardly 'missed' at all and it could boil the hopper in an hour or less.  My father, who owned the machine, claimed that the length of the exhaust pipe was critical and I am sure he was right as at some locations we needed a longer pipe to go out through the wall and there it really struggled.

[chuck foster]

my engine needed a muffler so this is how i made it.

i started off with these pieces


i welded short pieces of round stock to the plates that make the front and back of the muffler, this was done so i could machine them to size


after the plates were machined to size i had to cut the pieces off that i had welded on to the plate. it took a while to figure out how to hold the plates in the saw.
what i did was clamp the plates in another smaller vise and then clamp the smaller vise in the vice on the saw.




i then took the round piece of pipe that makes the body of the muffler and cut notches around the edge to let the exhaust gases out


the next step was to weld a short piece of pipe into one of the end plates, it is 1" water pipe (this will screw into the exhaust port on the engine)


this next picture is just a side shot of the whole bag of scrap iron


i hope to have it finished tomorrow night and then it is on to the timing advance lever.
