thank you for your reply i was thinking of the vacuum with a smaller tube but i was looking for even more options. the particle is a little bit larger then dust. kinda like shavings, its just large enough to make me worried. if i blow in im also thinking it might just get past the valves and into it more. but again thanks for the advice. i do like your first one with the vacuum cleaner and the smaller tube. ill try that once i get the whole thing installed again.
