    Default Armbase restore, Counterweight sleeve, Armboard restore and mod

    Next up a range of projects for a customer in London.

    This armbase had seen some wear with the arm pillar retaining screw thread stripped.
    The original solution was not ideal.

    I made a new slightly bigger thread for a grub screw, a second one to beef it up and a third grub screw to properly retain the outer collar.

    Should be good for years to come now.





    Next a Counterweight sleeve to fit over the original and increase the mass by 118g





    Lastly, a rework of the recent armboard I made.
    The tail turned out to be too long. I shortened it to fit. No charge.
    The customer had tried to enlarge the SME slot to take a different armbase.
    I refurbed it to improve the looks and function with a slight slot for adjustment

    Restored



    With larger slot. The SME armbase will still fit of course and cover the hole nicely.
