Hammond Organ foam job

- This is a look at the problem of deteriorating foam in the manuals of a Hammond Organ. This affects all Hammond Organs after 1963-4 and will, if left untreated, eventually get so bad as to be unrepairable. The only answer is to remove the foam before the problem gets too bad. There is a second part to this video, and I will probably post other updates later.

Excellent Video Peter.....thank you for making it available - still applies today in 2016.
Best news ever, found rivets all along the sides of both manuals, FELT, felt! :)
The Hammond A100 was produced between 1959 and 1965 . So , roughly one half of all A100's might be assumed to have the foam rubber dust excluder if that component was introduced in 1963 - 64 .
I do think that damp environments may speed up the process, but that's just my impression rather than having anything to back that up. The bottom line is that sooner or later it will start to eat through wires, and if you value Hammonds and want to preserve them for other people to enjoy in the future (they will likely outlive you and me!) then the work has to be done.
Thanks, I did remove the plates in the front and I did see two more bolts on top underneath the percussion and vibrato but didn't think those were part of it, believe me, I wish I could find a tech but for some odd reason techs who 'happen' in vegas don't 'stay' in vegas, lol!!
STOP...!!! This is absolute the wrong way to place the manuals. With the manuals up side down, the crumbled foam wil fall in to the furnarable 'ball-resistance-wires' and you aren't able to clean it up anymore. Only the normal position or back-side down is the safe position for the manuals to dismantle the back-plate.
There are two more bolts in the back and a small plate under the front rail to take out. However, I have to say that if you are struggling at this stage, that you might want to consider getting a tech to do the job for you. It is not for the faint-hearted! Getting the manuals up is the easy bit!
Sorry: Where are you...... PS this is pure genius.
I have a B3 96999 built in 1966 from what I can tell. I am the original owner and the organ has been kept in my homes ever since. I have no problems with it. I would like to know how to actually replace the resistance wires when I finally open it up. I have been trained by hammond back in the 70's. We never went that far into it, nor have I yet to run it to this problem with others that I have worked on.
Oh, I appreciate knowing the transiton years on this issue. I prob only have one more organ that would be affected by the problem. It is a beautiful A105. 1969. I suppose that if the organ has been in a good enviroment that the process would be slowed down? What do you think? I just hate to think about this whole issue although I know that it is a reality. I suppose most people would just go ahead and play the organ till there are no tones left. Very few that would know how to do this repair.
Where are based, Peter? Do you offer this service commercially?
How did you get the manuals off of the organ? I have an A-102 and I tried this past weekend, I removed the two bolt screws from the front of the organ, but there might be some more in the back? Can you give me advice on this, I understand I'm at my own risk, I just need to get rid of this terrible foam! Thank you.
I can't understand why Hammond used exotic resistance wire instead of ordinary copper wire and fixed-value wirewound resistors, unless perhaps such resistors were relatively expensive.
Finding some place to put an extra 549 wire-wound resistors in each manual would be a challenge. And then you have to consider the increase in assembly time, which would raise the cost of the instrument.
What process and products did you use to clean it up?
Wow! I really appreciated your video. I have only run into this problem once so far. It was on an A100 as well. I fixed myself with the help of a pro over the phone. I HOPE I never have to do that again. There was only one resistance wire broken at the time. Which is why I pursued the problem but I did rescue the other wise fantastic condition organ. What did you use to clean the goo off? Check out my latest videos with lots of Hammond in them. That would be "One" & Joy to the World" Also Hush!
Hi I wonder if you would know if this could effect my T202 dated April 1969? its a semi-conductor tone wheel model? I think it was assembled in Britain by Boosey & Hawks Thanks Mike Baker
Do you worry about lint?
ОК
puro pujido y no hay tal explicacion objetiva
how to destroy a beautiful instrument foam is made with allsorts of awful ingredients a friend used to make foam and spent an 8 hour shift in a mask rotten job but he was desperate.
