Mounting the buttons

The Problem

We get the occasional comment that a new button is already running wild. However, this is not due to the knob, but to the screw thread on the lid. The buttons are made fully automatic and are therefore always the same. It may even be the case that the fooled button on another cover will stay in place. Changing buttons is sometimes a (temporary) solution.

Of course, we have also replaced everything, already in 2004. The strange thing is that so far nothing has been left with us, just like with most people.

What we regularly see when people come here with the pans, is that the screw thread on the lid is not quite what they should be. There are several reasons for this. Sometimes the thread is rusting, sometimes the thread is eaten away. Sometimes the lids have been without button for a long time and the thread even taps ...

If the screw thread on the lids is not 100%, the thread only 'tackles' the top tips of the triangles that thread actually is. Sometimes even on two or three of those tips. Those tips inside the button are of course also made of plastic and then break off. Result: the button can not be fastened.

That is why it does not help if you only put a new button on the lid. This one will be finished in no time. After all, it is not the button, it's the screw thread on the lid. With the solution below you can usually use 'lame' buttons again.

 

What to do?

The best solution is to fix the knob with a  (steam lid) screw. It then becomes the same construction as with the steam lid. (The lid with a total of 3 holes, two for the steam and one for the screw.) On the outside you will not see anything and on the inside of the lid you will see a screw. So what?

Use a steam lid screw P522-127; it is made of stainless steel, has the right thread, length and shape and comes with a stainless steel waved ring. It is Withworth thread and can be hardly found in Europe. (Does anyone have a tip?) The steam lid screw fit perfectly with the 'normal' ring and knob, so it does not have to be a steam lid ring.

In this way, even the crazy button will sometimes 'pick up' again!
 

How it works?

Removing the old screw thread on the lid is often the most difficult. You can try to break it off, but pay attention that the lid will not show any dent! (Put the threaded end in the vise, putting force on the lid.) Sometimes the weld is no longer good and it works quite easily. Try to bend / turn in several directions, so you weaken the weld a little further. Patience works better here than violence and gives better results !!
If this does not work, then it has to be sharpened off. A Dremel or something like that can handle it. A angle grinder is too coarse, unless you are very handy with it... The intention is that the lid is not damaged! In any case, tighten the lid firmly. And ensure good cooling!

Tip from a fellow RenaWare user: "Especially after sawing or drilling, the stainless steel is prone to corrosion, the main reason being that when sawing or drilling, the steel becomes several hundred degrees on site with the result that the carbon present in the stainless steel burns and the structure of the steel is lost, leaving room for oxygen atoms where the carbon atoms were first present.
It is therefore very important that the temperature is not too high when grinding, drilling or sawing. Always cooling with water in between or using oil is a must. This always applies: not too high in temperature. In practice you always see the most corrosion on welded joints, drilling or grinding spots."

Then make the hole. First put a nap exactly in the middle of the lid at the bottom of the lid with a center punch. Then pre-drill with a 3 mm drill and in three or four steps always take a larger drill. The lid is very hard...! Careful drilling (!) until the chest of the screw fits easily through the hole. (10mm). Remove any burrs and remnants from grinding and drilling. Clean the cover well to prevent rust. (Dissolve residues of the tool in the stainless steel.)

Put the waved ring around the screw and push the screw through the lid. Place a ring x57-47 on the lid and turn a knob on the screw until it starts running 'on'. The whole must still be able to move now. Also note the positioning of ring and knob. The steam lid ring has a 'snap-in moment' for the knob because the knob takes the ring with it when it is turned.

Then make sure the waved ring is around the chest of the screw and push the screw with the chest through the hole in the lid. Turn the button further at the same time - that must first go easy again! Check that the chest of the screw is correctly positioned: the screw must now be able to spring in and out slightly. Finally tighten the screw with a screwdriver and hold the knob.

Do not forget to use the waved ring that comes with the screw, then the knob and ring are nicely tight on the lid, but not so tight that it will break when stretched and shrink due to heat. And so you can also losen it later. If you leave the waved ring away, the button will not lock properly. If only the thread passes through the hole, you will miss the strength of 2-hole screw thread. (Knob fast losens again...) It is made so that it fits perfectly this way! The screw is exactly that long that it 'runs' up to the end of the hole in the knob and the spring washer ensures that everything at the top neatly connects.

Done. That will last for years.
