Team build

[Jadecy]

sounds like things are going to start moving real soon. Are there any better prints of the plans? I was looking over the pdf I got from the web and it is really hard to make out some of the dimensions.

Ob boy this is going to be fun! ;D ;D ;D

 

[zeusrekning]

I started modeling the engine last night. I have found a few questionable or missing dimensions. The first one is View "CC" of the bearing, does anyone know what the height is supposed to be? I have it in as 1-1/4". If everyone (mostly me) can be patient, I hope to have it finished this weekend. I also agree with the two threads.
Tim
P.S. I had no Idea how small this engine was till I started modeling.

I checked Elmer's book and it is indeed 1-1/4".

Thanks for the plug Tin.

Mine ended up looking like this.

The shifter knob is actually a .177 air gun BB drill to fit the shifter rod.

Marv also did an impressive build of the Open Column with Reverse.

I feel I'm safe is saying either one of us will be more than happy to answer any questions
that may arise along the way.

I think this is a good choice for the team build and look forward to following the posts and pictures. Here are a few pics of my version of it.

Two questions? I drew the cylinder up @ 1-1/16" dia. with two turned down sections at 1/2" dia. It doesn't look correct. Also, on the crankshaft, is 1/2" stroke correct? It shows 1/4" from center to the #3-48 hole but it looks closer to the edge. Thanks for the help.

The major OD of the cylinder should be 11/16" (.687")

The stroke of the crank is 1/2"

Makes since now. Thanks Rick.

 

[zeusrekning]

Got it modeled.

 

[BobWarfield]

Zuesrekning, cool!

Is that Solidworks? Can you export it to Rhino3D? I'd love to have that model.

This is a fine looking little engine. I think the group has chosen well for a first project.

I'm getting well ahead of myself, but at some point we should do a set of "steam accessories". We'll need a boiler, of course, but perhaps a few lineshaft miniature machine tools or a dynamo would be cool too.

Wouldn't that be a kick?

Cheers,

BW

 

[zeusrekning]

BW, What extensions can you open with Rhino?

 

[deere_x475guy]

Zuesrekning, nice job on the modeing. I wish I knew how to do that. I have down loaded some demo programs but I never really get time to really learn anything before it expires.

Bob... give Alibre Express a try. The basic version is free. And for basic, it does a lot. It is also very very easy to learn.

Got it. Hated it. I made myself use it for about a month before giving up on it. I found Alibre extremely cumbersome and prefer Rhino3D by far.

zuesrekning, Rhino uses 3dm. It will also do IGES. There's a bunch of others, but it's probably easier for me to just draw it myself if you don't have either of those.

Best,

Wrong Bob, that message was for deere_x475guy... I remember reading on your blog about your adventures with Alibre (I was going to send you an email about your cylinder's being faceted... 2 second fix). I have Rhino as well, I like Alibre much better. It was easier for me to learn. But, as with a lot of things in the machining world... there is more than one way to do something. What works well for one, may not work for someone else. ;D

[deere_x475guy]

Ok Eric I am downloading the express version right now and will give it a try. Plan on me bugging you if I have questions..))))) J/K.

 

[zeusrekning]

Allright guys... Where are we at? Am I supposed to be building something?

 

[joe d]

Two things.... 1. As mentioned a couple of pages ago, maybe change the 3-48 threaded bits to 4-40? (Got a fair number of 4-40 taps that I haven't broken yet) and 2, I agree with zeusrekning, shouldn't I be building something? ;D

Waiting on Tin...

But we have decided the engine, we have decided the time frame... now we need to hand out part assignments. So to give Tin a hand, I believe we should be vocal and volunteer or make a requests for the part we feel comfortable with.

So? Team... what part do you want to build?
