Australia and New Zealand team build anyone?

[tel]

Gear cutting done, just got to drill and tap them all for M3 grubs and run them in in pairs now. Probably tackle a run of spark plugs next.

 

[Herbiev]

You have been busy Tel. I got all the bases cut and squared up http://emob1237.photobucket.com/albums/ff463/Herbiev1/image-1.jpg?t=1347610735
Still waiting for response from designer re hole positions

Meanwhile I'm halfway thru the bushes and hope to do the pushrod ends Mon

 

[hi speed scrap]

great work Tel, Herbie, looks great.
While you have been working, Ive been relaxing 1000kms from home in the
Hunter valley wineries region,tasting suitable Wines for my son Lee's wedding
tomorrow
But I will be home again monday, all I have completed is the valves and retainers.
Bit unsure about heads and ports, so have not continued with them, or do you
think I should continue as per drawings?

Dave

 

[Herbiev]

Dave. Continue as per drawings and I shall give Didier Yvron another message to try and get the missing info. Good luck with the wedding

 

[tel]

Yep, good luck to all involved, and enjoy the wine. They make, from memory, a rather fine Le Gopener.

 

[Kaleb]

I've been slowly making some swarf on this project, I've got one flywheel nearly done, but ruined my first go at a fuel tank support column. Ah well, these things happen.

 

[hi speed scrap]

Back on deck again, recovered from wedding etc
Dunno about the RAAF guys tho! They found the Le Mouthopener!!
Tel, I think the Le Gopener got shelved!

Have the valve seats all but completed as I have problem finding
suitable springs or wire to make them.
I havve however assembled 1 valve set with a slightly larger ID spring
and I think it will work well. (4.7mm ID)
However this is a deviation from the original plans. Not sure we should be
doing that.
Open to suggestions here!
Will post a pic maybe tomorrow, cant get macro to focus properly on
them as they are so small.

Dave

 

[Herbiev]

I just got it. Doh! LeG Opener. Only took 2 weeks. Dave, I wouldn't worry too much about small deviations as there are quite a few measurements missing there is bound to be some deviation. As long as we communicate well there should be no drama.

At this stage I won't put my hand up to build any of the parts, but if more detailed plans or any modifications to customise for the build are required then I would like to help.
This way everyone can also have an input into the look, material selection style for the build and then see exactly what the end result should be like.
Also if people needed to be able to make parts in imperial I could convert the parts perfectly for them.

Hay guys
This plan set looks like it needs a bit of work, why dont we get Ausdier to post his detailed workshop drawings for this Engine??
Pete

 

[tel]

That gets my vote Pete - there is a lot of info not there that needs to be.

 

[hi speed scrap]

Hi all,
finaly got the bucket to work! so here's the out of focus
pics from a couple of weeks ago (if it works)

Ausdier, I wandered if you had any problems when u did your 3D
pics of this engine,
I have a few bits that dont fit, as per supplied plans,
can u help us here?

I am Sloooowly fiddling with the valving desgn here.

Dave

 

[tel]

Lookin' good Dave, and I finally got all the gear hubs drilled, tapped and grub screws fitted today - so they are right to go.

 

[ausdier]

Hi Dave,
I can't remember if I had any problems with the plans.
I would have to look back over them.
The good thing about CAD is that I simply draw what I can from the information supplied and then basically fill in the blanks when I assemble it.
Then I annimate it and if there is somthing that doesn't work the CAD program will tell me what and where the problem is.
Even holes that don't match by 0.00000001mm won't go together so unless what I draw is right I can't put it together in CAD.
If things like fillets in corners are missing I look at what size looks right to the drawing and then make them to a standard size.
If you like I can post workshop drawings of the parts that you are having problems with.
Just let me know.

 

[Herbiev]

Ausdier. I wonder if you can supply the missing info on the position of the base plate holes and the missing info on the pushrod support. Thanks in advance

 

[tel]

Embryo spark plugs

 

[Herbiev]

Looking good Tel. That coin in the centre is my fortnightly pension

Finally finished the bushes. Base plates cut to size and waiting to be drilled. Just started push rod supports. Tiny little buggers aren't they ?

Hay guys,

seems to me a very common problem in TBs that the blueprints are not complete, lack some dimensions or even contain errors.

The downloads section contains a lot of nice plans, fantastic and inspiring. The sad thing about it is when I took a closer look at several plan sets, I found a lot of these errors.
A team build might look like a good start in model engine building for someone like me new to model engines (I'm no novice to metalworking), but doing a team built with incomplete plans scares me.
Especially in a team built parts are to be made hundreds or thousands of kilometres apart and this calls for very detailed plans, as far as possible free of errors and omissions.

In commercial machinery fabrication drawings for parts that are manufactured by another company are usual very exact made, with tolerances for nearly everything. Goal is to avoid any doubts about dimensions, tolerances, geometrical tolerances and surface finishes.

If You fabricate something in Your shop, its no big deal if something is missing, but if fabrication is scattered in 10 shops specifations for every part should be clear.

This problem is one reason I'm not really willing to join a team built now. Nevertheless I hope to read about progress of Your team built.

Good luck
Mike

 

[tel]

Rof}Yeah, it's about the share I get out of my pension as well. Bushes are looking good!

Yes Mike, most ME plans have errors and omissions - just needs your 'team' to be pretty well coordinated to get around it.

 

[metalmad]

Hi Tel
I must admit one look at that plan set turned me off real quick too but im glad you fellers are making progress
What are you going to do for a fuel system?
Pete

 

[tel]

Dunno yet Pete - with a little bugger like this a fuel vapor carb might be the best way.
