Gary75 Posted November 26, 2019 Share Posted November 26, 2019 So I started this week...... Normally it"s a case of if it ain"t broke don"t fix it, but I had to commence pre-emptive measures. [video:youtube] Quote Link to comment Share on other sites More sharing options...

Doc Tonewheel Posted November 27, 2019 Share Posted November 27, 2019 Definitely do it! I had Retrolinear remove it from my 1975 A105 manuals and they gave me the foam they removed. Fortunately, when the put it in at the factory it was a little off position, so it didn't really get on the wires, but the foam they removed was already turning into a gooey, sticky mess and the organ had spent its whole life in a living room in NJ before I bought it.

Gary75 Posted December 3, 2019 Author Share Posted December 3, 2019 Update After finishing off the 100 or so wires to be unsoldered, today with the help of my father we took the manuals out. The way we did it was take two wood batons, lifted the manuals up and slid them under the sides from the back. This then cleared the manuals from the scanner. The only other thing was to remove the centre wood block that the centre brass back panel screw goes into. Two wood screws and a tap with a small hammer. After that we placed a table at the back and made it the same height as the batons. Then the manuals slid right out without needing any lifting or risk of dropping to the generator. Rubbed some wax on the batons for ease of movement. You could remove the manuals on your own really using this method Called it a day today but I did have a nose around now they are out and touch wood, the foam that"s visible and touchable (left hand side) feels supple and springy with no sign of degradation. Hopefully it"s the same on the inside. Last picture is foam. I"m actually really enjoying it! upload image Quote Link to comment Share on other sites More sharing options...
Joe Muscara Posted December 3, 2019 Share Posted December 3, 2019 That's so clever it makes me wonder if that's similar to how they were assembled in the first place. Or, you're smarter than they were! Quote "I'm so crazy, I don't know this is impossible!

Gary75 Posted December 3, 2019 Author Share Posted December 3, 2019 I"m not sure if they"d have used batons to slide them in but it certainly works. You only have to lift the manuals up just enough to clear the scanner and pop the wood block off and they just slide right out. The height of the batons is 30mm. Width can be roughly the same. This way your not doing any lifting or any awkward holding. If only my C3 was as easy to move with the manuals in! Quote Link to comment Share on other sites More sharing options...
mate stubb Posted December 3, 2019 Share Posted December 3, 2019 I always removed my manuals from the front. Interesting idea. Quote Moe --- Link to comment Share on other sites More sharing options...
uhoh7 Posted December 4, 2019 Share Posted December 4, 2019 When I learned about the foam thing last year I panicked. But my RT3 (inherited a year ago) was made in 1960 TYG. What a relief.

Gary75 Posted December 4, 2019 Author Share Posted December 4, 2019 Partially removed lower manual cover today, seems to be tight at the end where preset board wires go into the housing where the preset keys reside. I think it"s just a bit tight and I need to be a bit more brave. It looks really clean from what I can see, none of the foam broke off or looks deteriorated [video:youtube] Quote Link to comment Share on other sites More sharing options...
mate stubb Posted December 4, 2019 Share Posted December 4, 2019 Hmmm. I wonder if the organ was rewired at some point. I've never seen the yellow/black wires attached to a manual terminal strip before. Everything I've seen has cloth insulation.

Gary75 Posted December 4, 2019 Author Share Posted December 4, 2019 I don"t know it"s history between 1973-1999 but I do know it wasn"t used for a while before I got it as someone had removed a valve from the Leslie where it was from purchase, which was a civic centre. I wonder how much of the organ(s) was in completed form when shipped from the US to be assembled in the UK. Is it possible some of the solder work such as harnesses were done solely by UK electricians/panel wireman and they used their own cable form.

bjosko Posted December 4, 2019 Share Posted December 4, 2019 Looks nice and clean there, great job so far. Will you clean the busbars also, while you have it apart ? I need to do the same job one day soon with my 67 A100. You can see some of the dentrite in the end of your last video, as also shown here : [video:youtube] Quote /Bjørn - old gearjunkie, still with lot of GAS Link to comment Share on other sites More sharing options...
Gary75 Posted December 4, 2019 Author Share Posted December 4, 2019 I"m not sure if I will yet clean the bus bars. One of the annoying things about living in the UK is their is no suppliers of Hammond maintenance parts or indeed any parts. I"d like to change the upstop felts while they"re out but your looking at $18 for a pair from Trek, then at least $50 for basic shipping to UK. Someone should get a dealership from home going and sell TWG/Trek produce. I"d do it myself if I could. The dendrites are noticeable on some areas, feels furry under the fingers! I"ll clean as much surface area as possible and then have a think about wether to apply some form of clear lacquer coating to stop it from returning. The foam isn"t sticky and still retains its springy feel so I"m really pleased I don"t have any cleaning/removal so far to do, aside from removing it from the cover itself Quote Link to comment Share on other sites More sharing options...
GRollins Posted December 5, 2019 Share Posted December 5, 2019 Okay, for those of us who spent the last umpty-years playing guitar/bass, then came late to the keyboard game, can someone give me an idea as to what's going on? I bought an early '60s A-100 a couple of years ago and I know that I need to do some maintenance on the drawbars because they glitch in and out, and the chorus rotary doo-dad rattles, so it probably needs some attention too, but what fresh hell is this? Are you guys trying to give me nightmares? Grey Quote I'm not interested in someone's ability to program. I'm interested in their ability to compose and play.

Doc Tonewheel Posted December 5, 2019 Share Posted December 5, 2019 Hammond organs used to use felt as a dust cover for the resistance wiring in the manuals. Starting mid 60's straight into the 1970's, they switched to a strip of foam (like you find on Anvil cases). This foam can break down into a sticky goo over time and corrode and eat through the very fine manual wires. Keep in mind that each resistance wire is hair thin and each key has 9 wires. Multiply 9x61 keys and you have 549 chances for the foam chew thru a resistance wire and eliminate a tone in your Hammond. See this link to determine if your organ has the foam. https://organforum.com/forums/forum/electronic-organs-midi/hammond-organs/50318-dreaded-foam-what-years Quote Link to comment Share on other sites More sharing options...
GRollins Posted December 5, 2019 Share Posted December 5, 2019 Thanks, I'll pop the back and look for rivets. I've also got a lot of the original paperwork, so I can check the dates--at one point, I had that tops in my mind, but it's evaporated. Grey Quote I'm not interested in someone's ability to program.

bjosko Posted December 5, 2019 Share Posted December 5, 2019 Gary, you might try Tonewheel General Hospital, www.tonewheelgeneral.com , still TrekII products, but perhaps cheaper shipping, or find other UK Hammond players and share the shipping costs.

WesG Posted December 5, 2019 Share Posted December 5, 2019 To be pedantic, Hammonds do not suffer from dendrite problems, they suffer from whisker problems. Whiskering occurs spontaneously on electro-plated metals, and is thought to be the result of residual stresses from the electroplating process. Our hammonds contain parts which are zinc or cadmium plated, for corrosion-resistance. https://nepp.nasa.gov/whisker/background/ Gary, if you have the manuals out already, you'd be foolish to skip cleaning the busbars at this point IMO.

Outkaster Posted December 6, 2019 Share Posted December 6, 2019 Yes buss bars are a big job but worth it. It makes a big difference. I did a job last year with a friend on a 1958 B-3 and it sounded great afterwards. Quote "Danny, ci manchi a tutti. La E-Street Band non e' la stessa senza di te.

Gary75 Posted December 6, 2019 Author Share Posted December 6, 2019 I"ve just ordered busbar lube and up/down felts from TWG. I"m not in any rush to finish the job and you guys are right, it would be daft to have it all stripped out and not do it. You have to get out of the mindset of 'well it plays and sounds fine so must be ok underneath" Certainly a good winter project when I can"t work outside in the warm!
