Does anyone know the outside diameter of the 38mm Cesaroni spacer?
The reason I ask is I was wondering if it's possible to use spacers in a snap ring case. I need spacers with an OD of 1.30".
For EX purposes only as using a spacer decertifies a snap ring motor, a Kosdon type grain spacer is the length of 1 propellant grain.The reason I ask is I was wondering if it's possible to use spacers in a snap ring case. I need spacers with an OD of 1.30".
I don't think any of the snap ring manufacturers offer spacers.
If they did, you'd need to use spacers designed for those cases, instead of spacers for another type of case. Otherwise, it would be an uncertified combination.

so it will not buckle when loaded by the forward closure, but thin enough so it doesn't weigh a lot.
Absolutely correct.Just to nit a pick..Wouldn't the proper sequence with spacer usage be from aft to fore: nozzle,grains, forward closure, spacer, forward internal snap ring. That is the sequence when using the spacer in my CTI 6G 75mm case..Should be pretty much the same in a snap ring case, yes?
