Mendel frame is wobbly

Hey guys

I have a question about the frame.

I have just assembled the frame and frame ends, jigging the triangular sides with J1 and when putting them together J2 apart as specified here.

The frame now rocks on 2 opposing feet like a wonky table. I need to shorten one of the (not so) vertical bar distance by as much as 3mm to remove the wobble.

My question is should I remove the wobble or keep the wobble and go with the jugged distances using some padding under one of the feet to remove the wobble?

Thanks

I think you need to keep the jigged distances the same but also get the feet level. Perhaps loosen the horizontal members and twist one triangle relative to the other so the feet are all on a flat surface and then tighten them again. The y-axis will bind if the two y-bars are not parallel to each other in the vertical plane, which they won't be if the feet are at different heights.

Thanks Chris

I will give that a bash - it means that one of the feet will be standing on the edge of a vertice rather than the flat.

Been *many* months since starting on this road but now I have a stable home with a study for my repraping and a garage for my heavier tools so getting on with it in earnest now.

Cheers

Why? If the the triangle is equilateral the feet should all be flat.

erm... basically because I did not really understand what you were saying... I thought you were talking about twisting one of the vertices..

Anyway, after I figured out what you were getting at I managed to sort out the problem.

Thanks Chris

What does the phrase "give that a bash mean"? Just curious.

I guess you are in the US then?

It means "I will give that a try"
