Maybe your LX door doesn't open as wide as it used to? Maybe a wee bit sluggish? Check out the flexible tube beside the hinge fitting. I knew I'd have to do this eventually - mine snapped in half. Electrolux engineers used clear Tygon (aka aquarium tubing), which at the time was all the Jet Age rage; they couldn't know this material hardens and breaks down into a gooey brown mass over time. Also reacts badly in contact with brass, which is what the LX nipples are. We player piano folks know Tygon and Perflex all too well. Anyway, this 'stiff & sticky' really slows down the door action sequence. Pictures show the exactly 7" long tube I replaced with thick wall grey player piano trackerbar tubing - this has the long life & flexibility to withstand the contortions the tube goes through when the door flys open, without binding. The brass nipple connector at the suction adj. dial was clogged with green/brown gum as was the nozzle inner sensing 'rivet', which has in fact a pinhole bleed on its end. I also inserted a ballpoint pen spring inside the nozzle end of the grey tubing where it takes that torsional 90 degree bend through the door frame to prevent collapse. The length of the tube is crucial as the tube must allow for folding when the door is closed. Too short and the tube stretches - too long and the tube pinches and kinks. 7". Now the door flings open, the nozzle bumper bottoms out with a satisfying thunk, and the demonstration bag I concocted filled with a shaped styrofoam block flys a good 12 feet across the room. Whee! I'll be doing this retrofit on the other LX's. Dave, a new member up here in Canada.

Thrilled to have stumbled across this group.
Thank you, Charles. I have admired your Theremin website for such a long time. Although I have always hankered for a theremin it wasn't until I happened to be in Ithaca visiting a friend at Cornell that I saw the notice that that very night Bob Moog was hosting a showing of the Leon Termen documentary, giving a demonstration of several models...and announcing the imminent availability of the Etherwave DIY kit. Whcih I promptly ordered from him and kitbashed & modified it into a wood 1930s RCA table radio shell as a self contained (power supplies/amp/speakers) portable theremin to play accompanied by any of the player pianos around here. As for uncured medical yellow latex tubing, it is too soft & spongey to do the deed and also latex breaks down within a few years, while extruded & cured natural rubber (or neoprene) specificly for automatic music instrument restoration has the ideal properties of long life, firm yet yeilding flexibility and as I said, the thickwall tracker tubing has the perfect inside and outside diameter. I have rolls of the stuff in all sorts of sizes to service the needs of pneumatic players and would be pleased to provide short lengths to anyone who asks, gratis in a snailmail enveope. I too have experience with liquid latex we use here in the prop shop. I soon intend to try the hose sealing proceedure with thinned out latex and a helper to keep the hose fully coated and clear of obstructions while draing and drying. I'll do a few test runs first with iretrievably hard cracked hose bits. I'll be reaming the hose first with alarge bottle brush on a long pole attached to a drill to avoid those trapped hairballs inside. | ||

The problem with my LX's here in hot humid NC is not only the tubing-but the ejector mechanism and spring in the body is corroded beyond recognition-the cleaner works though. | ||

Latex & hoses
Liquid latex is thinned with plain ol' tap water. I shake it up in a large lidded glass pickle jar and let it settle a while so the micro bubbles rise to the top and burst. Exposure to air causes the latex to thicken and set so keep that lid on til ready to pour. I'm going to suggest filling the hose half full, then having a buddy assist in sloshing the mixture all around like whipping a skipping rope and wrangling the hose upright to drain while connecting to a vacuum exhaust port. Gonna let gravity do its job and mount the vacuum up high in the basement rafters to let the hose dangle while being blown...and leave it hanging straight to dry a couple of days. Should be trying this this weekend...experiments on trashed hose bits bodes well in terms of concerns of the latex coating being pulled away from the surface under suction after drying thoroughly. With just the right consistancy it penetrates far enough into the interior hose layers to dry & lock the surface in place. Don't forget to shake & blow a generous heap of baby or talcum powder through the length before bending or flexing. Latex sticks to itself and you don't want to damage that brand new liner after all that irreversable toil. I'll dump in a whole package and agin use that buddy to shake it all about and blow it out... outside. Btw, many of my Electrolux hoses that came with XXXs and LXs are woven in all vinyl - spiralling parralel dashed lines of light blue & grey on a cream ground. What year would they be? | ||
