Here is a quick follow up that will be even more useful for drilling collars. I found that piano wire will work better than drill bits to drill tuning pin collars. The wire will not break. You can use size 16 or 17 with the 20 gauge needle. A piece of 23 or 24 will work for the 18 gauge needle. I cut a piece about 2 inches long, straighten it, and chuck it into a good quality pin vise that then is chucked into a regular drill chuck. The pin vise is very narrow and fits nicely next to the pin. Drill in about 3/4 inch and insert the needle and syringe. Give it about 1/2 cc or more per pin. The question about being a veterinarian- Rumor is true, I am one. I am a veterinary pathologist. As mentioned once before, I had a double major in biology and chemistry in undergrad school at U of Ill. Thus the interest in the chemistry of adhesives. I am semi-retired from research and diagnostics at Plum Island Animal Disease Center where work is done on animal diseases exotic to the US. I still teach there in four 2 week courses each year. I have been tuning pianos and pipe organs for about 10 years. I planned to do this in my retirement. I retired 3 years ago and have a full service piano business and restoration shop. I started on pipe organs with a church organist from NYC who built organs. I learned a lot. I learned the piano business from my brother-in-law who is the showroom tech for Steinway in NJ. He worked in the Steinway and Sohmer factories also. So the name Classic Piano Doc is legitimate. I have a DVM and PhD. Doug Gregg Southold, NY 11971
