    Default Spot On

    Well done on the repair of the"Spot On" indicator.
    What a great name.
    Hope it still gives years of service, sounds like it has some good memories for you.
    regards

    Thank you Bruce,

    Yes it has The chap, Stanley, who gave it to me was very much a mentor, not just in engineering but life in general. To a great extent he was a father figure ! He always had time for me, which very few others did.

    Well the mill is back up and running. I've not done anything more than switch it on and run the motor, and change the speed gears.
    Ok there is no real load on it but it certainly sounds different. I wouldn't say its any noisier but the rhythmic chugging has gone. I did find another problem but it was easy to solve.

    The speed change knob on the side moves the dual gear up and down to select high or low gear. In the low position it moves the gear upwards. I found that it didn't move the gear far enough to engage the teeth fully. There was always movement of the knob past the ident position, but it never stayed there. I rotated the plate with the three ident dimples in it 180 degrees. Blued it and refitted the knob moving it to each extreme took the knob off and the plate. Then drilled three more dimples. One at each end of the mark and one in the middle. It now moves the gear up enough to engage the teeth in both gears fully.

    So at the moment I'm a happy chappie.

    Thanks Guys for all the kind words and good advice.
    Best Regards:
    BaronJ.

    Well done BaronJ,
    I have enjoyed this entire thread.
    The easy part is the advice, the hard part is putting it into practise.

    Hi All,

    I used the mill today to finish off the job that started this whole thread. Anyway the slitting saw had a crack in it ! I hadn't noticed it before. Then it broke into three pieces as I tried to get it off the arbour. Not having another slitting saw I pressed an old 125 mm circular wood saw blade into service. I had to turn up a suitable arbour for it and put it in the drill chuck to use it. Job done.

    One thing that I have noticed, the mill runs on a lot longer than it did before when you cut the power. I assume that this suggests less losses in the new gears.

    Now where did I put that chunk of 80 mm cast bar...

    Good work!

    I dare say that the reason your mill runs on longer is because of the angular momentum embodied in the mass of the spinning gears as opposed to the plastic?

    Could be wrong, but it was the first thing that came into my mind.

    Cheers,

    Simon
    Girl, I don't wanna know about your mild-mannered alter ego or anything like that." I mean, you tell me you're, uh, super-mega-ultra-lightning babe? That's all right with me. I'm good. I'm good.

    Hi Simon,

    Yes you are probably right. When it had the plastic gears the spindle was always heavy to turn by hand. Now you can feel the motor being turned and its a smooth motion with no tight spots even in low gear.
