How much flocking material?

[A McEwan]

Hi,

Just wondering how many rolls of the FLO ver dark flocking material I'll need to do my incoming 10" f5 Dobsonian. Anyone done theirs with it? It's a GSO if that makes any difference.

Thanks,

Ant

I'd say you need between 3 and 4, if you end up having too many rolls you can always re-use on another OTA .

Ooh that much? Thanks for letting me know.

If you want to flock the whole thing. I'm not 100% sure so I'd send FLO an email. Bear in mind that the tube will be 1.25m long

Without wishing to state the obvious, if that's what it is....

.....the circumference of the tube is the diameter x PI

So, an OTA of 11" or 28cm approx, will have a circumference of 28 x 3.14 = 88cm

So the total area you need is approx 88 x the tube length, say 125 cm = 11,000 square cm

You should be able to work it out to the nearest number of rolls from there if you know the roll size?

Yup I'll get the calculator to work...

Each roll has 4500 square centimetres, so if 11000 are needed, yep - that'll be three rolls with some left over. Quite a bit left over probably, but that's handy to have!

Cheers!

Just did a quick web search and that does seen to be right for a 10"
