Hi Marc,

 

Thank you for the feedback, I will proceed with getting a quote together for this project.

Chris,

Our collaborator from INFN (Italy) have responded to your questions. Please let us know if you have any further questions. Additionally, please keep in mind that the components of the design can be modified to fit materials which would keep the cost low. Please let us know what changes should be made to achieve this. When quoting please itemize as much as possible and keep in mind that the hoist rings do not need to be included. We have access to 5000lb capacity, 3/4 inch thread hoist rings.

What ever the standard tolerances for manufacture should be good enough. Please let us know what "standard" would normally be.

Thanks
Marc

Hi Marc,

On following the information requested.

-          The structure to realize is a carpentry with the aim to give stiffnes to the “RICH Module” and at the same time to allow it’s lifting.

All the connections between the components of the structure will realized by screws through slots, made in cross directions (see the attached picture) in order to absorbe the dimensional and geometrical deviations.

So, not stringent tolerances have been foreseen (general class of tolerances can be intend as coarse).

In any case, the components are to be considered as "carpentry products made with care", the maximum obtainable without subsequent machining operations (with the aim to contain unnecessarily high costs).

 

       -      Attacched the requested step file.

 

Hoping to have satisfied the requested clarification …

 

Best regards

Dario Orecchini

Hi Chris,

I will pass your questions on to the collaboration. They will be able to provide an answer.

Hello Marc,

 

Ed has passed this quote on to me to work on, and I have a couple of question after reviewing the drawings.  

 

1.	Would you happen to have .step files of these components that you could share?  I need to generate some sketches of the various brackets and tubes in order to get piece part pricing quoted.
2.	Do you know what kind of tolerances are required for this assembly?  The drawings do not have a tolerance block, and they only specify a tolerance in a couple of places.  The most economical way to build this assembly would be to have all of the brackets laser / waterjet cut to size and then weld the parts together.

 

Thanks for your help,

 

Chris
