This might appertain to railway modellers or Dihorrama modellers more than boaters in general, but thought you might like to know.
The other day I was trying to get the dregs out of two bottles of 2 part epoxy so put them into boiling water to soften the glue up.
After a few minutes I mixed it in a small margerine tub.
As soon as the mix reacted chemically,(within a minute or so of mixing.not immediatly) it ballooned up , fizzed away for a few seconds and then set in a conglomeration that looked like a mix between chalk, moonrock and pumice stone, and then went hard, retaining that shape.
I tried it again with some newer stuff and it did the same.
In the end it looked as though a large lump of rock, and I thought it could be usefull for open cargo well decks, scenery and such, as it has the consistency of rock without any weight.
Has anyone else come accross stuff that could be used for detailing by chance or mistake.

What did it smell like? Sounds to me that you may have released some noxious (if not toxic) gasses! A bit like what happens when far too much catalyst is mixed with the resin. Cheers. BY.

[nhp651]

funnily, brian, there was no smell at all.
 not like a hot mix i sometimes make in grp.
nothing, just a fizzing as it expanded greatly.

[Colin Bishop]

just a fizzing as it expanded greatly.

Lots of things do that.

Ive done this just thought it was my mind ...

I threw the remains of unhardend 2 part in the fire ..it fizzled up like the pray foam insulation ..it burned to fast to see what it was like but just kept it in the back of my head in case i find myself having to ditch a batch in lue of "honey-do's"

Is that painful, Neil?    Is it caused by something you eat?

Unintended inventions? a guy was soldering something and had a soldering iron on his bench along with a syringe full of ink... the iron came into contact with the needle and the ink squirted out... 'Eureeka' he said 'I've invented inkjets'.. and he ran off down the patent office!

Is that all it is? I really thought printers were much more complicated than that! By the way, whats the difference between an "inkjet" and a "bubble-jet"? BY.

Bubble jet uses a smalll heating element to boil a bit of the ink so it forms a bubble to force a drop of ink out of the print nozzle onto the paper. Inkjet uses the piezoelectric effect to cause the print nozzle to constrict forcing the ink out

Thank you. Wish I hadn't asked now. Too much brain overload! BY.

You don't want to know about dot matrix then....?

[catengineman]

Or lazer ?

Well, are you going to tell us?????

Bryan... Like duh! You should stick to your short stories and leave how things got invented alone.

[wombat]

Or dye sublimation....

And don't forget thermal transfer or electrostatic plotting (bl**dy messy things)

Just an earnest seeker of knowledge old son. The time may well come when you might be interested sufficiently enough to ask a question simply because you don't know the answer. I would hope your reply was meant in "fun", but it sure didn't read that way to me.

[Peter Fitness]

I'm still waiting for some explanation of all the above technical terms. Like Bryan, I'm also a seeker of knowledge, I love learning new facts, it's just that I have trouble remembering them

Accidentally catching a front bumper of a Vauxhall Astra with a heat gun and finding that if you do the resat of the bumper it comes up like new.Apparantly the plastic that they use on the vauxhalls can be revitalised and bought up to look like new saving money by not having to buy bumper dressing

It was question? I didn't realise...

Yes, inkjets are more complicated than that. They guy sitting at his workbench that day only invented the spurting inky bit, I've no doubt he had other colleagues to help the company design the printhead, the paper transport mechanism, the transformer and any curcuit boards, the on/off sitch, the waste ink pad and whatever else is in them.

But those bits are the consequence of a deliberaely thought out plan, the guy touching the syringe with his soldering iron was a pure accident.. and a 'Discovery by Mistake'.

Inkjet v Bubblejet? The first is a group name for a type of home printer that uses ink to print, the 2nd is what canon term their inkjet printers that print by heating ink... they both mean the same thing.

Piezo crystal-type printers are still 'inkjet printers':

OK boring hat on......

Dot Matrix - or impact matrix. This uses a set of seven, nine or 24 pins in a row. These are driven by solenoids that push the pins onto a ink coated fabric ribbon that presses the ribbon onot the paper. The impae is built up by scanning the head across the paper. Noisy ans slow but good for mulipart stationary

Dye Sublimation - this is a method used by Tektroinx (IIRC) Special wax ink is used - this turns from solid directly to vapour (sublimation - hence the name). The ink is flash heated to create a small puff of vapour which then condenses and solifies on the paper.

Laser - this uses a photoconductive roller - the roller is charged up to a high voltage. A laser is scanned across the drum to form the image - the light causes the bits of roller that it strikes to lose charge. The drum is coated with the toner powder (a plastic/carbon composite powder) - this sticks to the charged bits of the drum. The paper is charged with the opposite polarity of electricity - as it passes over the drum the opposite charge transfers the tomer from the drum to the paper. The paper then goes through a pair of heated rollers that melts the toner powder into the paper, solidifying it.

Electrostatic Plotters - these charge the paper with a high voltage at the points where colour is wanted - the ink is squirted or sprayed at the paper and sticks to the paper - some need to be fused to fix it , other just dry. These are fast but low quality

Thermal Transfer - this uses a solid pigment on a carrier film or ribbon. Where colour is needed on the paper, the transfer film is pressed against the paper and heated. This transfers the colour from the ribbon/film to the paper.

Wow!...ask a simple question and this forum comes back with an encyclopedia! Now all I have to do is to assimilate and store within the now limited space between my ears. Thanks. BY.
