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.

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

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

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.

What are you going to do for a fuel system?

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