Measured the pipes at the right point and used the bit closest to the needed dimension. Then with careful use of a rasp bit in a batt. powered drill made all the holes just about perfect. One trick was that after rasping to get it close, insert the pipe and you can see where the circle is out of round so you'll know where to remove a little more material to get it round and fitting.   John V

The ones sold in Home Depot type places are in = 1/8" increments but there is a professional tool mail order house that sells a set graded in 16th's from 3/8" to 2.5". With that set, you rarely, if = ever, have to ream the holes. There is also a very helpful pipe size gauge blueprint on the ATOS chapter website at http://atos.stirlingprop.com/knowbase.htm and it is available as a .gif = and also as an Autocad drawing. I used that pattern to build a rackboard gauge out of a piece of 1x12 that I ran through my plane until it was 5/8". It gives me exact hole sizes that correspond to the fostner bits.   -----Original Message----- From: DIYAPASON-L@pipechat.org [mailto:DIYAPASON-L@pipechat.org]On Behalf Of John Vanderlee Sent: Monday, September 09, 2002 9:14 AM To: Residence Organ List Subject: Re: [Residence Organs] Reaming rack boards     We made a rack board by buying one of the inexpensive "import" forstner bit sets.
