I have a regulator where some of the leaves are damaged and I need to replace them. = I will cut them out of stock lumber and plane them to the correct thickness. Can anyone tell me the best way to prepare new raw lumber for application = of hot glue?   -----Original Message----- From: DIYAPASON-L@pipechat.org [mailto:DIYAPASON-L@pipechat.org]On Behalf Of David Scribner Sent: Saturday, January 17, 2004 1:41 PM To: Residence Organ List Subject: Re: [Residence Organs] Reservoir Releathering: Choice of Leather     At 12:35 PM -0500 01/17/04, Keith Zimmerman wrote: > >I will be releathering three reservoirs.

OSI appears to have precut and skithed gusset kits for certain sizes = of >reservoirs.   Keith   1. - Looking at the OSI catalogue they list "bellows" leather and Columbia lists "rib" leather - both are one in the same - a heavy leather for the hinge strips of the reservoir.   2. You are correct - the gussets are the corners of the reservoir. - Here again both OSI and Columbia sells "gusset" leather   3 - Correct again although not all reservoirs have these - depends on who built the reservoir originally. Also, there are very light weight "patches" at the inside of the ribs between the gusset and the rib hinge usually made out of lightweight Cabretta.   Referring to your later post about preparing leather - yes, all the parts should be "skived" or thinned along the edges. This is not an easy task if you have never done it before. It can be done by hand but takes a very long time for a beginner and also you can end up with a fair amount of waste. The Cabretta patches, or "darts" as Columbia calls them, do not have to be skived.   In the long run, i would suggest that you talk to both OSI and Columbia about getting both Skived Gusset sets and Skived rib strips. Sandy at OSI and Darlene at Columbia are both very helpful people and very knowledgeable.   A couple of suggestions about Hide Glue, and these are ones that i picked up at the lecture this Fall at the AIO Convention. Adding a small amount of salt to the hide glue will help with the "open time" of the glue - regular table salt is fine for this. Also, adding 2 to 3% of Glycerin (plain Glycerin from the drug store) will add flexibility to the glue.   i have some other notes from the "Hide Glue" lecture at the Convention that i will try to type out and send to you. It gives the ratios and instructions for mixing hide glue.   Hope this helps   David DIYAPASON-L: a Discussion list for owners and builders of their own Residence Pipe Organs.

Eugene (Gene) Dunnam" <dunnam@phys.ufl.edu> Date: Mon, 19 Jan 2004 11:41:15 -0500   Greetings- I'd be leery of operating any blower on its side, by which I'm assuming you mean with the motor/blower shaft vertical. Motor [and perhaps fan, depending on design] bearings are usually designed for operation with the axis horizontal. In this configuration the weight of the blower fan plus the motor armature is distributed over the bearing surfaces [at least two, normally]. Vertical operation throws this weight onto the bottom shaft end & requires a thrust bearing, or motor/fan shaft bearings designed to take a thrust load.   Shantz can advise you on this.   Best wishes,   Gene -- _____________________________________________________ | F.
