The are sure to be guides of some type to keep the slider moving fore and aft in a straight line, but I do not remember their composite or construction. There is no wood to wood contact because the slider is suspended by the spring action of the grommets in the bottom board of the windchest and of course the felt gaskets under the toe board keep them off the wood above. The lube, which David suggested may be "Mac's Lube" is not at all sticky like Slick 50, so does not attract abrasive dirt and dust. You must remember, I am relating details I saw only briefly, and that this was the very first organ action I had ever seen. I am just with 12 months experience understanding organ construction at this point, and was only 8 months at the time I viewed this combination action. I assure you that N&S is no where near living on any edge unless it is the upper edge of "state of the art". They are a highly successful organ builder with an enviable backup list of contracts, and they have this chest building formula down pat. The design can be easily adapted to many different situations and allows them to concentrate on the more important tonal issues rather than having to come up with different chest design schemes for every new instrument. I am also sure there are many details of the design that I did not see, or am able to relate to you, yet are equally or more important to the success of the design. I was merely trying to convey what I perceive as "the way it's done" by a modern organ builder of considerable note, and not suggest it is the only way to do things. Cheers Mike   "David O.

(for the = sliders)   And, the slippery stuff is called "McLube". AFAIK, its intended as an industrial die lubricant. I've never been certain of its chemical makeup, but will see if I can find the can and look. I *do* know that it is the slipperiest substance I have ever encountered...!! (I accidentally got a little on the shop floor once...it created a hazard for weeks!) Also, = last I recall, it runs about $150/gallon.   Each hole in the chest grid is ringed with felt (the "gasket"), then the (lubed) phenolic slider, then the slider seals, which hang free-floating under the toeboard itself. (no "spring" involved)   If y'all give me a day or two, I'll try to take some pictures of a = cutaway demonstrator chest we've built. (I've been meaning to do that, anyway!) Maybe (listowner) David could put them up on a website somewhere?   Hope this helps clear it up a little anyway!   Tim   At 10:11 PM 1/16/02 -0600, you wrote: >Mike, >N&S use polycarbonate (e.g. "Lexan") for their sliders?

It does not =   stain or get abbsorbed.We shoot in the track on the mast of our sail boat ounce and a while to make pulling up the main sail easier. I worked at General Atomic some years ago and they had cans of spray on Teflon I thing but that was nasty stuff. We ended up sending parts out to = be coated with something slippery of site. Have fun Dennis

It does not stain or get abbsorbed.... Hey, Tim... How good would this stuff be for coating the groove in the console for the roll top? I have been using Teflon paste, but the McLube sounds like it might do a better job. What do you think? F. Richard Burt ..

The fact that they are installed free floating into the = counter sink below each pipe toe hole is an effective, simple arrangement. Elegantly = simple in fact.
