Pressure relief holes

[Steven88]

My Loc Big Nuke currently has only one 1/8” pressure relief hole in the booster and one in the main section. I believe this should be sufficient if they are kept open. However, especially in the main compartment, my deployment bag and parachute take up almost all the space and the vent hole tends to be hard to keep open. What is the solution to this? I will be flying up to 9,300 ft with this rocket. I do have 2-56 sheer pins holding all the sections together but am wondering about maybe a second vent hole per section so that one is always for sure open? Is this not necessary or can you have too many vent holes? Need some advice... thanks

With the added shear pins, you’ll be fine.

Should be fine. Most people put vent holes towards the top of each section. Upon boost, the laundry shifts down to the bottom of it's section, keeping the vent hole clear.
