Air raid siren V1.1
Description
printable hand siren with planetary gearbox. v1.1 reinforced sound wheel frame has been added I will add to connect the gear of 12 teeth with the gear of 27 teeth, I use steel 8mm studs in size . My shaft is an 8mm stud with a length of 235-240 mm . I take bearings in size from the catalog and measure the dimensions with a caliper. this is for those who could not figure out which bearing would fit there if something doesn't work out for you or you couldn't figure it out - don't blame yourself, blame me, I'm usually guilty of everything. I will try to fix everything and help you if you like the idea, like it. I am now making a ratchet improvement. when the mechanism does not work, it is difficult to turn the handle, I lubricate it with oil. I don't have a video account to show loud and powerful now the war can start anywhere and you may need to notify your loved ones and neighbors urgently as never before, but electricity and communications will no longer work, in which case you will need this thing
