  • Key replacement on Model BC

    A friend recently acquired a BC (estimating late 30's). While trying to perform smears, it was discovered that the waterfall keys have sharper corners than models from later years. The sharp edges make it painful to use as desired. Question: Can the BC keys be directly replaced by later generation waterfall keys (e.g. B3/A100/M series)?

    Had that issue too.
    Replaced the sharpies with later smoothies.
    Used M and M2 playing keys IIRC.
    BC playing weight can be adjusted with those spring fasteners.
    Used a stack of 13 nickels to set my weight.
    Smears sound amazing with that chorus genny added!

    Later models without the adjustable springs can't be individually 'weighted'.
    A good idea to see what they are set at before removal.
    It took 15 nickels to drop/play a natural on this BCV when placed at the front edge of the key.
    Took off a few nickels of weight to suit my taste.

    I have an early '37 BCV. Built in Montreal,third one ever made up here.
    The cabinetry and wood grain are nicer than any later models I have.
    A100/251 A100/147 A102/222 B2/142 BV/147 BCV/145 M3/145 M102/145 M111/770 L101/760 T222/HL722 M111/770 no B3/C3!

      Thank you so much for the reply. So, in your case, would any of the primary models have compatible waterfall keys?

      M/M2/M3/A100/B3/C3/RT3/D100.......RT2/B2/C2/......late 'V' and early 'RT'.
      Anything mid 1949 or newer.
      In my case?......what?

    Any "waterfall style" Hammond key will fit. But it's a lot of work since you have to re-weight the entire keybed.
