EPOXY and POLYURETHANE, random jottings

[Paul H (admin)]

Yes tongue in cheek

A note from UniBond Exterior PVA used in the building industry and BS5270 certified.

NOTE: This product is only waterproof when mixed with cement. UniBond will not bond together two non-porous surfaces or PVC, hard plastic, rubber, polythene or nylon. It is not suitable for areas of constant immersion, such as swimming pools and water tanks, or as a waterproof coating.

Thanks Graham, I have taken all that on board, to use an apt if hackneyed phrase.
Yes, I like the experimental freshness of Duckworks, and even the preposterous comments that pop up, they often lead to something slightly less preposterous and quite useful.

Thanks Paul, any red wine involved . . . ?  :)

Re BS5270 I've checked the EN numbers and both UniBond Exterior PVA and Bostik Weatherproof Wood Adhesive are EN 204 D3. I have some of the latter here and I might do a couple of silly immersion tests with it.

Hello?

Re "Luckily all of these have mostly the same members."

Sweeping statement - do you believe that?

My impression is that there is hardly anyone on SFD, and that the cliques on Openboat, DW and HBBR are completely different.

Do you dislike this topic?

Mike

I am continuing this Epoxy and Polyurethane thread on the Duckworks Forum only. Hassling with 4 Forums is 4 times worse than hassling with just one. Life is too short.

I'm not biting.

You go off and have a good time there, rather than having a pop at those of us here who get along just fine.

This forum is a bit sporadic, but it depends on who'd building what at any one time, and whether or not any unorganised events are being disorganised.  Other than that we get along fine, and much prefer not to have "hassle".............................

Errrr? If this is "not biting", I am the Pope.

I was the poppee, not the popper.

By "hassle" I merely meant that I was spending far too much time on 4 Forums, I soon realised that being on 4 Forums was a silly idea in the first place.

Here are the scales I use - they are small electronic, taring platform scales:

 

On the left, 4" x 3", is the 50 gramme scale, 2 decimal places, 2 CR2032 flat batteries, "Truweigh On Balance TW50-A."

On the right, 4.5" x 3", is the 500 gramme scale, 1 decimal place, 2 AAA batteries, "On Balance MTT-500".

Both model no.s have probably changed by now.

I personally need a lot more tiny mixes than bigger ones, down to one gramme, but more usually 3-10 grammes, so I use the 50 gramme scale a lot, for better accuracy.

I rarely need a mix over 100 grammes.

Each person has to look at his own frequent mix sizes and select a weighing range, e.g. if I had to manage with one scale, I might have one 100 gramme scale, with one decimal place, and borrow the 3000 gramme electronic kitchen platform scale for anything over 100 grammes, which would then be accurate enough. The 3000 gramme scale was £10 from ASDA.

For the small scales, I would first search Ebay, then Amazon, and then, if no joy, the Net in general. They will be cheaper than when I bought them, but have not checked recently.

I prefer AAA or AA batteries to the flat CR2032 batteries because I always have them around.

PS: I have now found the On Balance MTT-500, 500g/0.1g resolution scale on Ebay for £12.48 delivered.
