<html> <body> Hi, Yea, I think Wim's on the right track here. Newton Hunt's "Guide" lists jobs by the number of hours it takes to perform each (approximately). My standard pricing procedure is to take my cost for the parts and multiply that by 40% to the customer. I then calculate the number of hours it takes me to do a certain job (I used to use "The Guide" a lot before I had done many of the listed jobs). Multiply that by my hourly rate, add it together with the cost for parts, and send in the bid. Ain't math wonderful? Oh, I also often "pad" the estimate by 10% or so to provide for unforeseen problems. After all, an estimate is an ESTIMATE, not the bottom line.

In that case, you can probably answer your own question. If you are only replacing hammers, does it take longer to remove upright hammers than grand hammers? Is there time difference in traveling, spacing, and burning upright hammers and grand hammers? Are you including regulating the action too, and is there a difference between the two.   Wim   </blockquote></body> </html>
