    I love being an engineer .....

    GASES CAN NEVER GET THROUGH A RUBBER SHEET HOWEVER THIN.
    I was a co-worker with an engineering laboratory for two years, and I can confidently contend that this given working scheme using the RAE detector is technically obsolete. The RAE detector will not be able to recognize volatile organics unless the rubber is separeted from the racket. The air samplings ought to be taken on the sponge side, rather than on topsheet. The obvious reason is that if some glue stuff or booster incorporates organic additives, then RAE system will be able to tell the presence of these additives by PPM scale. ITTF did passed by the common fact that rubber, however thin, is a material impenetrable for gases. Once a time I studied an army gas mask in a military camp, and rubber material did not let any gases in at all — nor mustard gas, no zaman, no sarin, neither novichok.
    Of course, I couldn't stand hand down looking at this improper actions with RAE device. Course, we shall change this irrelevant procedure in the near future. To their best credit, ITTF understand this too, they welcomed my plan and so forth. I love my being an engineer, indeed.

    I love boosting. My favorite booster is falco platinium. That smell burning my nosehairs is my ambrosia while I apply THICK layers alll over my rubbers sponge.

    I love boosters especially Seamoon! Do not let anybody discourse you from using boosters. 😂

    The title is incorrect.

    I agree. Anything good would be too expensive.

    The RAE detector will not be able to recognize volatile organics unless the rubber is separeted from the racket. The air samplings ought to be taken on the sponge side, rather than on topsheet.
    I agree.

    At least not a rate that is dangerous.

    Sampling should be done that the edge.

    However, gases will permeate through just about anything given time. My company makes controllers that are used to make 1 and 2 liter pop or soda bottle. I was given a tour on how the bottle were tested. Hydrogen is used to test the bottles because its molecule is relatively small and will permeate through the plastic pop bottles over time. This happens much faster with hydrogen than carbon dioxide. There is a ratio of how the fast the hydrogen will diffuse through material relative to how carbon dioxide diffuses. Using hydrogen for testing allows the tests to be done faster.

    Now, how big are the Seamon and other booster molecules? Chances are they are big enough were it will take a long time for the gas to diffuse even through the sponge, so the ability for the detectors to detect booster gas is probably going to be small if at all. I doubt any booster gases will be detect through the rubber in a quick test.

    Another issue is that there are closed and open cell foam sponge rubbers. It will be hard for booster to seep through the closed cell foam sponge rubbers.

    While i have the attention of all the assembled engineers and experts may you clarify please : I was under the impression that all my H3 rubbers were CLOSED FOAM..........
    but the boosters penetrate these foams real good ???????????????????????????????????????????

    I agree with lodro. about the website upgrades..
    Why not use something basic and free like PHPBBS?

They used to hang around the ceiling when you let them go and shriveled up quite quickly and ended up in a perverted little shrivel-bag on the floor. where did the gas go ?????????????????? You can experiment and seal the inlet with some silicone but the gas will still escape. Surely it does not go through the rubber, right ?? We already have established that this is impossible

    While we are complaining about the new website.
    The advertisements on the right are covering up the comments.
    I can read the the extreme right hand part of Lodro's comments if I move his comments up above the OVTCHAROV INNERFORCE ALC picture.
    I shouldn't need to do this. I haven't needed to do this in the past.
    I am viewing on my 2015 Mac Book Pro now ( Safari ). However, I have the same problem with my Fire tablet and iPad.
    When making web changes, one must have several platforms to test against. Not just Microsoft Edge, Firefox or Google Chrome.

    Helium molecules are only a little bigger than hydrogen molecules. Helium molecules are only two atoms big but helium is a bigger atoms than hydrogen. ( Am I conducting a chemistry class here? )
    The TT rubber manufacturers do not state if their foam rubber/sponge is closed cell or open cell. So how does one know if boosters will work on the rubber you have? The people selling boosters only want to sell booster so ignorances is good for them.

    i wonder if the benefit of bigger and more prominent ads is what dan and co were aiming for in order to increase revenue. Having a logically constructed and functioning forum as we had before seems to come a distant second

    I've always been very appreciative of this website / forum, but the new website has been 'live' for over a year now, yet the progress seems to have stopped long ago.. The dark mode that I along with a few others have been long waiting for in the 'bugs fix' thread feels so distant now.

    The adds are still covering up part of the responses. NOT GOOD.
    A good mechanic can assemble a car. In fact, I bet most are not engineers.
    Engineers optimize things. Find the best way given constraints.
