    Press fit dimensions?

    Yes, in one scenario.

    Press fit dimensions?

    Thanks to everyone for sharing your knowledge and "opinions". It has finally occurred to me that I need to become more friendly with my Machinist handbook.

    Press fit dimensions?

    Amen!

    Press fit dimensions?

    For the ignorant, I would think that metals and sizes would play a part in press-fitting one metal into another but my question is, how does one determine what the dimensions should be? As an example, .500 male brass into .500 steel, should the male be .500 or .5005 or what? Thanks for your...

    Tap holders for the feeble.

    Threading is not one of my favorite things to do in the shop. I made a tap holder as Joe P. posted and it worked very well, with one exception. No matter which tap I needed for the job, the tap follower was always configured incorrectly (pointed vs crown). So I came up with this idea so no...

    Morse tape in lathe.

    I am somewhat surprised by some of your comments/tone. I have owned the lathe for 45+ years and have never had any trouble of any kind except for one item and that was the dealer's fault. I had paid extra to have it wired for 220 but when it arrived it was 110 and that was incorrectly wired with...

    Morse tape in lathe.

    Thanks for the information Norman but this seems to not provide a definitive answer, it can be either-or. I was hoping someone would have the lathe and would know from experience. Even that would not be absolute as there are different possibilities. It is not critical for me at this time, I was...

    Morse tape in lathe.

    I tried but was not successful so gave up.

    Morse tape in lathe.

    That seems to be the closest to the adapter that came with the lathe but does not match up precisely in the MH at least with my limited knowledge. Thanks for the response Chris.

    Morse tape in lathe.

    I checked these in MH but none seem to match the adapter that I have. Thanks for the suggestion.

    Morse tape in lathe.

    You may be correct Tim, I admit to being ignorant in my understanding of the data in the Machinery's handbook but I have not been able to find anything with the dimensions that I have with the adapter.

    Morse tape in lathe.

    My apologies to all who have responded to my question and I have not responded and I will not go into the "why". Your responses are appreciated.

    Morse tape in lathe.

    Thanks for the info Martin...it is not a MT 2 in the spindle as there is a sleeve that reduces to a MT 2. much larger but not a MT 3 as it is also too small. Perhaps a 4 or 5 and I have found the specs so hopefully will be able to compare.

    Morse tape in lathe.

    Does anyone know what the MT of an old Rockwell 10" lathe is? I have the manual but cannot find the info in it.

    Steel or brass?

    Thanks for the info Brian and for responding. I had the idea of the different materials in the back of my mind but thought there must be a reason that PMR would use brass. BTW, I enjoy your postings, they are quite interesting.

    Steel or brass?

    In a cast brass cylinder, should one use brass or steel for the valve? Is one better than the other? I have a PMR #3 that I have started on and since this model engine building is new to me I like to make a prototype with on-hand materials. I just made a valve from some old 3911 steel but not...

    Tap holder from years ago.

    Great idea, it certainly looks stable.
