LIST, I just spoke with Denair technicians with regards to the Palm Nailer tip. They are providing a blueprint drawing of the attachment made for Baldwin Co. at no charge. At one time they produced the correct head for Baldwin and eventually stopped producing the part. They basically said they have considered producing it again, especially now that their product has gotten so much attention from the rebuilders, but rather they would send out the drawing or maybe even publish it on Pianotech. For those in the same position as I ( just bought the nailer and extremely eager to use it) be patient and the drawing will be made public very shortly. They have already done all the homework making the perfect head...take advantage of their R& D department. PS...as a customer friendly company, Denair is tops on my list. Their tech staff is a joy to deal with.
