The work you guys have been doing recently in here is f**kin boss. I have been incredibly impressed with the quality of blasters being produced by some of the contributors around here.
I live in Australia, and as such I don't have access to imperial size PVC, imperial size rubber washers and 1" PETG, so I have a few questions I'd like answered so that I may search for alternatives locally.
1st, everyone mentions 1" PETG coming from petco, I assume from my searching that it is a part for an aquarium gravel filter, however I'm not sure. Does anyone have the 'pet store' name for this product so that I can search for it more efficiently? is it a replacement part? does it come from a particular company or is it 'petco' brand?
I have seen some gravel filters with tubes that look about right online, however I'm reluctant to spend $25-30 to find out, and have yet to find the tube on its own. Any help information is appreciated.
Secondly, when finding rubber washers for the creation of a plunger head what relative size is appropriate?
Every thread i see says use xxx pipe with xxx washer, however I cannot tell how the washer fits in. Should i be looking for a washer that fits perfectly inside the tube? or should it be larger so that it bends into a cup like shape? if so how much larger? should the washer be closer to the OD or ID of the pipe?
I have done a lot of modding work, made breeches, machined a lot of plastics etc etc so I hope these questions are more justified than the average noob ones - I'm looking for a push in the right direction rather than the information handed to me on a platter
