Vertes dividing head failing ????

[ksor]

I have got one of these second hand and found out that something is wrong when tightening the lever for holding the head in a specific angel.

Did any of you have the same problem - I thing there is weak point here in the Construction.

You can see more details here:

It looks like it could be brazed without great difficulty, baring that make a new one. Can I assume that it has a slight taper and this locks the shaft, or is it something else.

No taper - just tightning a lever that the shaft Locks.

I think it's NOT a good contruction and will always break loose again - right:hDe: ?

Hi Ksor
I also bought a Vertex deviding head of this type second hand, and after several years of use am still Happy with it.
My thoughts on this are that anything can be broken if someone trys hard enough.
Either buy or make a new part and use it in peace my friend.

Now I'm back on this project !

I have made a sketch/drawing but MAYBE I have some problems with that configuration:

1) will the bushing be fastened in the long run or will it loosen ?

2) because the bushing is PRESS FITED and then sawn at point B - will the two halfs then "pop out" and ALWAYS clamp the shaft (not drawn !)

Look here: http://kelds.weebly.com/vertex-delehoved.html last pair of Pictures !!!!

As always translation to the right under the menu line !

The bushing is unnecessary. Your original failed because someone tightened the tensile stress sensitive cast iron way too much. The part will last forever if made of free machining steel with some lead content. Integrate a springloaded clutch (two brassplates and a spring) on the lever to protect it from hobby-Schwarzeneggers if it makes you feel better

I plan to make the part of steel (type UNKNOWN !) and I thought the bushing would good to prevent scratching of the shaft - but maybe it's overkilled !

What does a "springloaded clutch" look like - do you have a link ?

Now I finished the project:
