[dsg-eic_dirc] Damping system for barboxes

[Tyler Lemon]

Hi Greg,

Thank you for sending the info about the foam for the EIC DIRC shipping crates.

To avoid using spray glue, we'll use heavy-duty, double-sided tape to affix the foam to the wood. It should work just as well without as much mess.

Looking at what McMaster-Carr offers and the quantity we'd need, I think our best option would be to get 21- 48" x 54" sheets and cut them to size.
The numbers I used to calculate this are below.

Piece
Size of One Pad
# of Pads from One Sheet
Total # of Pads Needed
# of Sheets Needed
Long Bracket
3.5" x 24"
30
60
2
Short Bracket
3.5" x 6"
90
60
1
Crate Bottom
20" x 36"
2
30 (five per crate)
15
Extra Padding
N/A
N/A
N/A
3
TOTAL
21

McMaster-Carr's website estimates that everything we'd need would be delivered in about one week. (Side note to take into consideration: if we need more than 24 sheets, the lead time jumps to 4-5 weeks).

We can talk about it more Monday and verify the numbers.

-Tyler

Hi Tyler,

I got some more information from our friends in Indiana:


  1.  https://www.mcmaster.com/products/foam/laminated-super-cushioning-polyurethane-polyethylene-foam-sheets-and-strips/



-I believe this is what we used in 2018.  This is available in different thicknesses, and I do believe there are two different sizes used depending on what gap we were trying to fill.  Seems that I adhered these pieces to the crates using a spray-type contact adhesive.



  1.  Most of the gas system was built using push-to-connect fittings and tubing, right out of the McMaster-Carr catalog:

Cheers,


Greg
