Donations - Craft Material

[Henry Sands]

After moving up, I have some arts/craft items I think the space could use and I no longer have the room for:-

A number of A4 sheets of light sign plastic (good for laser cutting)

a litre of 2-part polyurethane resin

a light duty ultrasonic cleaner

A 1-litre tank hobby air compressor (permanent loan, low duty cycle! usable for crafts/light work only, maxes out at about 70psi with the pump constantly running, not suitable for a solder pump thing before anyone asks)

Crafting odds and ends, including many paintbrushes

3 large blocks of non-sulphurous plasticine suitable for silicone mould making

I'd like to get an artsy/crafty area set up in the space if other people want it too

[Sam Kelly]

Very very much yes. Until we have an area set up, how about storing these in the Dark Cellar where the existing paint stocks are? There's lots of unused storage there.

That's it.  We're not messing around anymore, we're buying a bigger dictionary.  -  Tibor Fischer, The Thought Gang.

Well I was thinking of setting one up near where the sewing equipment is, just by moving a few tables around temporarily 

[Henry Sands]

On an equal and somewhat related note, anyone play wargames? :D

[Martin (Crypt)]

So what exactly would an artsy/crafty area involve? how big would it be? where would it be? and will it enable any artsy/craftsy stuff to be done that can't already be done?.  Is this just a storage area for artistic related stuff or what exactly does this involve?

This might be a cool idea, but think we need a few more details

[Sam Kelly]

That also works well!

Hell yes for the wargames though :)

[Henry Sands]

2 tables? Basically like the electrics area but for crafts, a selection of small tools would be available along with cutting mats/materials ect.

Crafts is a messy business and having it in one area would keep the general mess down, preventing people setting their laptops down in pools of paint/glue and generally keeping the space usable for others.

If I'm using an airbrush, I don't accidentally want to coat the side/back of someone's laptop, obviously cardboard screens stop the worst of it, but it gets everywhere.

[Charles Yarnold]

Sounds great.

2 tables is a lot of space... what sort of demand are you expecting?

[Sam Kelly]

12 people turned up at the first artists' subgroup meeting last week.

While I was there there were people using it for painting, fabric hacking and I used it as well. One of the tables is more of a "desk near all the draft and fabric stuff"

I think looking at it as an area for one subgroup is the wrong way to go about it, its quite multipurpose by everyone.

--

[tgreer]

I have no objections to it, I just don't want space being limited to a certain subgroup...

[Henry Sands]

you mean like the electronics area or the biohackers lab?

[Charles Yarnold]

I agree :)

At the moment about 1/2 a desk is used up by equipment, much less than the electronics area. I don't think anything else needs setting up permanently there.

[tgreer]

Discussed on IRC and resolved. Thanks Henry.

[SamLR]

Is it possible to get a quick run down on what the resolution was so that those of us not on IRC know what the score with this new area is? 

Cheers

the ham radio guys use that corner because their antenna is there and their radios are stored in the safe, need to shuffle around so there is space for both groups and the safe is accessable

[Fergus]

Any idea if the polyurethane resin is still there and in good order? Would like to make some backgammon pieces and have as much experience as an armadillo has playing the piano.

its still there on the shelf, what we don't have is any rtv silicone to male a mold with.

[Fergus Macdonald]

Awesome. Do you need to use silicone? How easy is it to make a mold. Happy to buy some silicone if required.

Regards,

Fergus

Its pretty easy, I don't mind showing you, we have all the material except the silicone, its not exactly cheap though.

http://www.tomps.com/condensation-cure-rtv-silicone-c-55_1_7_5.html

This is your average RTV silicone for moulding, the higher the number the harder and strong but less flexible it is, a medium strength should be fine.

[Henry Sands]

http://www.tomps.com/value-budget-rtv-silicone-kit-5kg-to-26-5kg-soft-shore-20-p-476.html

this is a budget cheaper option, but the silicone is quite poor quality, if you get either get the slow catalyst, as we have no way to degas or pressure cast, the added time lets more air bubbles escape

[Fergus Macdonald]

Awesome - thanks for the offer. What do I need to create the mould in the first place? Presumably I'll need to make something which will act as the master and be used to create the mould to make the other pieces? If so, probably makes sense for me to make that first.

Regards,

Fergus

[Henry Sands]

you need a master, a flat surface and something to act as a wall to keep the silicone in, the last two are easy enough

[Fergus Macdonald]

OK, thanks for the tips. I'll get thinking about how to create the master. I'm guessing this guy used existing pieces since he's got a mould with 9 pieces in it: http://rolandbutter.blogspot.co.uk/2010/03/00400-casting-pieces.html

probably, easy way to go

[Fergus Macdonald]

Any idea what colour the cast pieces will be and how well they'll take paint?

Fergus

We have a degassing thing.

There's a hacked up fire extinguisher and a vacuum pump kept under the small lathe. I've used it for silicone degassing and it seems to work decently well. I'm not sure where the fire extinguisher is these days, but it's quite obvious if you find it: it has a clear plastic lid instead of the usual extinguisher parts.

pump and degassing chamber found!

Should have said this eariler...

The pink seal for the lid is quite sticky and picks up crap really easily. It's worth trying to brush off as much as possible/pick off the larger chunks otherwise it's a bit leaky. Also there's some funny small holes drilled in the lid which may leak. I plugged some of them with silicone rubber, but that may not have worked 100%.
