[pianotech] Double-Wides

[Farrell]

Thanks Dale. Reasonable approach on the diagonal cut. However, the straight cut gives the additional advantage of keeping the bandsaw upper guide blocks right at the top of the wood being sawed over the entire cut - just a better chance for a perfectly (or nearly so) straight cut. I was starting this with a blade that already had some miles on it - but still performed admirably.

I haven't used #2 pins in one of these blocks - only #1 pins. And I honestly don't remember what my final bit size was. I do the Ron N two pass drilling method and I simply always drill a few holes in the block in an area outside the tuning pin fields and pound in a few pins for testing - I just always feel better doing that.

    Hi Terry
    On my Last double wide block I confronted the same issues as you describe here so my solution was to just cut the delignit block at a diagonal angle & then resaw so each piece was equal & in the same shape roughly as  a single block. ie wider on one end & narrow on the other. However with a good glue joint doing it as you describe should be  of no concern.
   With what size drill bit do you recommend on this type block for no.2 pins ? 
    Well Done

  No, not those - but rather pinblocks - and more specifically, Delignit capped Multilam doublewides.

  Yup, made up my first doublewide Delignit capped Multilam pinblock this weekend. Client of mine has two large pianos to rebuild and after going back and forth on dimensions we both realized it would be a lot easier if I were to simply make him up a doublewide pinblock blank. So here it is!




  Full double-width. The Delignit blanks are an inch or so larger than the Multilam - so the final capped block is the size of the original Multilam double blank.




  Even though I have a very nice bandsaw, it can't resaw an 18-inch wide (tall) piece of laminated European Beech. So I cut the double-wide Delignit blank in half and resawed the halves. The Delignit cap on my pinblock blank ends up with a joint running down the middle - but it's a nice tight joint - one should have no concern even if a tuning pin were to bisect the joint.



  Blatant commercial ploy: operators are standing by.......  ;-)
