Regulation Capstan Wrench
« on: July 07, 2015, 04:05:30 AM »
Hi,

I just received my order from EP service in which there was the famous key to making all the settings of the action. Surprise : the key is too small  :(

I unmail to prevent shipments EP service, the answer is: "Sometimes It Does not fit, we adjust it Normally with a Dremel".

They could at least check them before sending them to clients.

Until this key, I was made a tool that worked very well with a Facom Key size 5mm and a piece of plexi for only 7 €.

I also received the mold to make the pyramids on reeds. I'll give you news when I have tried...

The larger side of that wrench fits the lost mostion and letoff CAPSTANS on almost all Wurlitzers. It is not for adjusting the dampers. It does NOT fit letoff adjustment on 112's (non A) and earlier.

That tool is awkward to use. The better tool is on ebay. It fits all 140 series, all 200 series, and the 720.

What exactly are to trying to adjust?

You are better off reselling the tool from EP service as an acoustic piano wrench. That is what it was designed for.

Steve, thank you for all these precisions.

I'm new in the world of Wurlitzer, but I am not completely stupid. I know very well to what use this tool. I put it on the arms of damper just to take the picture.

So I explained that he is too small to catch the let-off Capstans and lost-motion Capstans. Here it is clear.
it is a manufacturing defect, and so I want to prevent anyone who wishes to order this tool there is a risk that it is not adaptable.

Give me the link to buy your tool on ebay please.

No, it is not too small for those capstans. The larger end fits those. The outside rounded part is so big, that it makes it difficult to fit in between action parts. I used to use one of these until I found the other angled tool. The part of the capstan that you grab with this tool is slightly tapered, so you should find a spot that it fits.

I was not insulting you, I just didn't understand what you wanted to adjust. The outside rounded edge of this tool should be grounded down a little so that it fits inside the action better. ( between the parts) The inner part should fit the capstan just fine. ( the larger end) then bend the tool so it is easier to use without smashing your fingers against the keys.

If you take a key out, the large end of the tool should fit the capstan perfectly. I would do this before altering the tool. If you have a 200 series with an "A" the lost motion capstans are on the whips and not the backs of the keys. It still may be easier to turn them if you remove the keys.

I'm not sure how to add links here. It's the Wurlitzer letoff tool on ebay for 140/720/200 series.
You may not need it though because you made a tool.

I do not say you insult me, I'm just a little upset that you might believe that I could try to adjust the dampers with this tool  :-[

In short, I understand everything you told me, but I assure you that the key is too small, some-of the position.

I'll do a test with the mechanics dismantled. Anyway I'll take everything apart because I received the CLP Protek and I'm going to be lubricated.

But I think the best thing to do with this tool is grind the inside of the key. But before I will make a more detailed picture for you to see what I say.

Know that I appreciate very much your answers on the forums, and I hope you continue to help me ...

When you say key, you mean the wrench, correct?

I'm just having a little trouble understanding. I would be very surprised if the inner portion is too small. That looks exactly like a standard acoustic piano capstan wrench. One size is very small, and the other fits the Wurlitzer ( on the tools that I have tried)

Now, you said it's too small for SOME OF THE POSITIONS. It fits some capstans but not others? If so, that's why I think you need to grind down the OUTside part of the tool. If it fits some capstans,it should fit all- they don't vary in size. But, the outside is so large it makes it nearly impossible to grab onto some capstans depending on how they are turned, because of the tiny clearance between the capstans.

I hope my explanation is clear.
Again, I really do not think you need to buy a new tool.

Here are two pictures :

 - On the first we see that the key is not large enough to catch the screw.
 - On the second, after grinding with the dremel, everything is ok.

I've never seen anyone have to do that before, that is unfortunate. I have owned at least two of that exact tool and never had to do that. I did grind down the outside of the tool to make if fit better between the capstans.

For future reference, the angled tool sold on eBay fits perfectly with no alterations needed.
