[CAUT] pin-block plugging?

[John Ross]

I see what you were thinking now. Yes I suppose the glue would have an effect. 
I had used the 1/2" plug, I am assuming now, you used the 3/8".
How about putting them in with epoxy?
Were they hard to put in, because you did not have a glue pressure release groove?

  Thanks John,

   

  I think the hole-boring, bit-sizing, feed-rate thing is likely okay, as it's the same regimen we use for boring new blocks and the results are what they need to be.

   

  I think I'm doubting the strength of that thin layer of wood, and the glue joint. maybe I need to let that glue cure for several days?  

   

  Anyhow, you've had good success with spot-plugging John?  No need to up-pin?

   

  Best regards, 

  Mark C.

   

  PS Hi Wim, I did try a resin repair on a pin-block back when this was being promoted (maybe in the late 80's?), but haven't since for the reasons you describe.

  The glue should have nothing to do with a hole being too large.

  Bad glue would cause the plug to become loose.

  Webb Philips has a glue he sells to put in the plugs.

  If you have to use a #2 pin in a hole you say was drilled for a #1, then either you are using the wrong size bit, or your drilling speed is wrong.

  I have found Ron Nossaman's double drilling with two different size bits to work well.

    Now and then I run into a situation where plugging a tuning-pin hole and re-drilling seems like the only option. IOW, neither an over-sized pin, CA glue nor an emery paper shim will work.

     

    I've tackled this fairly carefully, even using a small portable drill press clamped to the keybed to get a precise hole, but I never seem to get a good result:

     

    I've used plugs from both economy blocks and Bolduc blocks. The plugs are a tight fit to the wood, and really have to be driven home. I've used carpenter's glue.

     

    Nonetheless, the results always seem to end up the same. I bore for a 1/0 pin, then end up installing a 2/0, then up-sizing to a 3/0, and often a 4/0!?

     

    Anyone have success with this? 

     

    Over the years some of you must've plugged and re-bored entire pin-blocks. What's your secret?
