Paraffin tuning : MEGATHREAD

I have tuned two moon sheets with PO (only on sponge) recently.
(Again, thanks to the information in this forum and special thank to Peter79)
I used speed glue to glue the rubber onto the blade. After 1 week of play, I notice that the cut sheet on the blade has shrinked. At the moment, I can see wood at the edges of the blade. Overall, the degree of shrink is not substantial.
So, the lesson learned here is, we should wait for the sheet to completely dry. For my next tuning sheet, I will wait for atleast 1 week (7 days) before I glue and cut the sheet.

Thanks Peter. I will try that for my next moon sheet.

this is what I use:



you can buy them at any general hardware store

2 layers of parafin oil and 1 layer of baby oil is enough.
Parafin oil only without baby oil is not good enough.

What I want to do is to make a more lively H3 National. faster than untuned.
Waiting for 5 days is to make the tuning effect minimal, but better than not tuning at all.
It last forever if you put baby oil on it.

If you remove the waterbased glue from the sponge, you must retune it again. If not no need to retune.

i think paraffin opens the pores and baby oil fills them. Thats may be the reason why the sponge is more dynamic.

Baby Oil and PO is the same thing - just that Baby oil is as pure as PO can be with vapour pressure 0.0 -> undetectable. Baby oil is much thicker than lamp oil and the effect holds longer.

What has been said about lamp oil not making the sponge softer is not correct. While it doesn't soften the sponge within the first 2-3 weeks it will soften the sponge *considerably* over time eventually making it so soft that it needs to be replaced. Also: Lamp oil contains other harmful substances and the PO in lamp oil is not really pure PO i.e. *it's very dangerous* and contains illegal VOCs (this is the very reason why lamp oil tuned rubbers play great in the first week until the VOCs have fully evaporated. The spin and feeling will then be gone, but the speed stays. Tuning multiple times with lamp oil will eventually get you an completely uncontrollable rocket launcher. Baby oil has a different effect. It doesn't really soften your rubber but it increases the catapult effect noticeably and makes your rubber more bouncy, *thickens the sponge* and makes your rubber faster. Note that the effect of baby oil lasts many weeks. Consquently, if you overdo the tuning you can trash your rubber.

None of this is close to real speed glue as far as spin/speed/control goes unless you tune with lamp oil with lots of VOCs and buy new rubbers every other week.

IMO, I will not do that on a new sheet of T05.
I tuned on chinese rubbers/sponge only, because these sheets (chinese sheets) usually feel "dead" when new. For example, I felt that my moon sheet (without tuning) lacked of speed, not lively and simply "dead". After tuning with PO, it is "alive" and more bouncy/ increase in speed.
For Tenergy rubbers, you will not have this problem ("dead" when new)and the sheet can be played immediately when you glue onto your blade, so tuning is not necessary.
However, some had experimented on worn/old sheets and they claimed that the PO increases the grip and etc.

I use paraffin oil only to expand rubbers that shrink and no longer cover the blade. Too many rubbers shrink.

so i went to shoppers drug mart to buy some baby oil..... and i was looking at the different brands and seen that some are make with mineral oil and some are made with paraffinum liquidum

i ask the pharmacist what the difference was, she said two different drugs same result...... but of coarse that is if we are trying to make a babies bum softer!!

so which baby oil to use?????  mineral oil based.... or paraffin based

i'm thinking mineral oil bcuz i would already be using P.O. lamp oil

and another question.... do you mix the baby oil in with the P.O. or do you apply in separate layers to the sponge?

Johnson's baby oil small bottle, gives more spin and speed to rubber?

I have a few questions for the experts:

1) is it normal that a rubber tuned with kerosene ( = paraffin oil = lamp oil) smells of gasoline?

2) if I tune one Hurricane III with kerosene and another one with baby oil, after 3 months will the two rubbers play the same? (I mean equal to each other, not to how they were 3 months before)

3) How long will it take until the two rubbers are regular, in the sense of VOC emissions? (provided I have tuned with just one layer of PO or baby oil, avoiding to create a reverse-dome and stretch the topsheet)

Thanks

how sure are you?

where did you read it? Thanks

Dude! i mixed a bottle of RC(n-heptane) with lacquer thinner(toluene, acetone,methanol etc.) Goo off( Xylene, acetone) and Ronsonol lighter fuel(naptha) and lamp oil for tuning. I know its very ilegal and harmful but i hope it i'll be badass.
