Drilling techniques was----: CA Glue for pin blocks

[reggaepass at aol.com]

 Hi Dale,

I didn't drill this block, but will try to find out the details about bit size and type, RPMs, rate of feed, air cooling of the bit and any other possibly relevant details.? Ditto for the 411 on the tuning pins.

Thanks for continuing to share your treasured insights with the list. 

I salute you,

Alan Eder

? Hi Alan

?? I've had similar results with Bulduc Blocks I think its a good block but I had enough discrepancies to gear up & make my own. They are way more even & I'm not suggesting any one do that, & ? Hey?Farrell makes a great Block you can buy.

?? ?That being said, out of curiosity what brand & size of tuning pins are used,Drill size, Drill press rpm, & are you using air on the bit?

?I try to keep up on what others are doing.? You know it is wood after all & it's not? perfect medium.? I drill at about 1400 rpm With a .257 bit for no twos.? I just special order a bit from Fullers that is .255 which I'm going to try. For dryer climates & my blocks & think it's a better choice. I think it may be better for The Bolduc as well.

? The other issue?may be stringing technique....??Trix wraps 3 ?the coils on the pin then drives them in close with a palm nailers & then a few whacks with a hammer.

? I'm now sure that Ca glue use in pinblocks is the all time favorite topic on this list.....grin....I've never used it......yet!






A matter related to this thread: ?I have a client with a recently rebuilt piano, including a new (Bolduc)?pinblock. ?The torque is acceptable on many/most of the tuning pins, but is too low on several. ?The low-torque pins are not so loose as to not hold (at least, not yet), but make it harder to tune accurately and, especially, to get into a good groove as one moves along from string to string. 









So the question is: Should I use CA on the looser pins, even though this is an otherwise healthy, new block (I'm guessing some drilling discrepancies are the culprit), or would CA now present problems when we restring again (on this same block) down the road? ?And, if I should NOT CA it, what then?











Thanks,











Alan Eder
