Bobs Knobs for a Starmaster Dobsonian

8) Bob Morrow of Bobs Knobs really went all out fitting me up with a set of 4 secondary mirror collimation screws.He made them a small diameter so as not to intrude into the light path of my old style 14.5 inch and as my scope was the First Starmaster that he ever did he was an extra cooperative vendor.Bob has me measure the pitch of the threads and take some pictures of the existing screws he even called Rick to cooberate the sizes.I feel that for all the work he did including sending me 3 size lenghts of collimation knobs to try before he made me up 2 sets(one for my friend Bill's 14.5) to try and he is charging me a small fee for all of his extra work.It is so gratifying to get such service from anyone these days.Thanks Bob.
