Nice!

Wes, how do you set up the chuck on centerline?

One method I understand is to put a dowel pin in the lathe chuck and align the chuck to that.

Cheers,

BW

Got mine today. Very professionally done!

Finished the flywheels and con rods this weekend. I need to go get some mailers, but they should go out this weekend or early next week.

Cheers,

As mentioned elsewhere, I finished the flywheels and con rods last weekend. I need to get some mailers, and then they'll go out either this weekend or early next week.

Best,

Wes:
They are turning out nice
finished cutting the slots tonight the first few are a few thousands asymmetrical and the bottoms show some milling marks the slots will not show.I will do some photos tomorrow. Still need to install he handles and make the studs. I made 16 blanks and so for only one is trashed so should not be a problem getting a dozen good ones.

I'm out drilling holes now) I wont be the guy holding everyone up) I just work better cornered like a rat.

The chips are flying now!! do not feel bad I am furiously working on the disks still need to do studs and make or scrounge springs. maybe I should look for a dozen click pens @ the dollar store and steel the springs from them.

Bah! Go into a commerce bank and grab a bunch of free pens. They have 2 different sized springs in them!

All the holes are drilled. I'll tap them this week and when the 4-40 hex screws that I just ordered get here I'll be mailing my stuff off. Tapping will be quick. Then I need to polish them to match the bearings.

I knew the deadline was coming but I ended up stalling till the end. I always do that. But it looks like things are coming together pretty nice. I can't wait till the next build)

Wes

Dude! What are we going to build for the next one? Check yer PMs... sending you one.

 

[Brass_Machine]

I have another suggestion for the next engine.

This one seems a little simpler to build then Chuck's single. I would like to do Chuck's Single, but I think we should wait a couple of builds for it.

You can find the plans for the twin HERE. It appears that this engine can be increased in size as a build log HERE States. More details of the valve for the twin HERE in the single cylinder version. The picture is of the larger version.

What does everyone think?

Hi Eric,

Don't want to be involved with the build, but can give you an insight into this little engine you are proposing.

It is not such an easy proposition as you think. A certain chappie I know has tried to build this one to double size (and it really does need to be, as it is too small in its original form). Failure ensued. So unless you have exact drawings for all the dimensions for the larger version, I think the members might struggle with it to get it to run.

The main problem is getting the ball bearing lift at the right time. A few thou out and the piston won't go over TDC or gets blown back the way it came.

It will also require a fairly high pressure to run, because it has to have the force to open the valves as it comes to TDC against the air being compressed in the cylinder. It is almost a 'set it to run at high speed and leave it'.

It is really an engine for someone who has experience in tweaking to get it to run. Mutiply that by a dozen or so, and you could find yourself in trouble.

Just a suggestion.

I likes the look of the little twin myself. It's a few less parts as well. Cylinders looks like a great job for someone with a CNC, I may have some bronze to contribute.

Just my .02

I would like to get in on the action, if that is ok.
I am still setting up my home shop but I could still crack off a few pieces.

Kevin... You have been added ;D

Anyone else?? Please check the list in the first post to make sure you are there!

BTW... PowderKeg has agreed to Co-Captain this one with me. Lets hear it for Wes!

Eric,
I agree with you that Chucks engine needs to mature a little bit more before being used for a team build.

I also agree with Bogstandard that the twin cylinder Kerzel engine in it's plan form is probably too small. Although there are team members that would not have a problem with the 0-80 tapping and the 0.020 holes, there are some that would probably struggle with small parts. I have build a couple of "Bash valve" engines and they do take a bit of playing with to make run properly. And properly does not include slow running. Even the double size engine would take some playing with.

Sign me up for this coming team build. That is if you will still have me after the above comments. If the list gets too large for the coming project, you can bump me if desired. I always have enough projects going to keep me busy and my feelings won't get hurt.

Consider yourself signed up ;D You are a welcome addition (as is everyone) ;D.

A couple of suggestions from me...

Elmer's Radial (#11)
Elmer's open column twin (#44)
Bog's open column twin
One of Jan Ridders Flame Lickers. I like the vertical!

Suggestions are wanted and needed.

Eric

 

[kustomkb]

Thanks !! ;D

I like the Poppin. I think it would be fun If built twice as big. That would make it about the size of my other fire eater.
