Hi everyone!I have created a silicone model (see attached pic) but it is in separite pieces and I was wondering if I could get some advice on the best way to attach them. The model is made from…Continue
"Ah, quite big. Which gives you more room. If you make two separate creatures, then your crossover isn't a problem, but the challenge becomes how to link them effectively. Perhaps making a small bulb on the end of the 'tube' and a…"
"Approximately 35 cm x 15cm. I have attached a sketch which is more of a likeness to the final sculpt (apologies for the crude subject matter) . Initially I thought it best for the crossover section to be joined as one but thinking on, if I do the…"
"My initial thought is that you would need a central lift-out mould section.
Can you give me a bit more information on it? How big will it be approximately? Presumably it will be animated. Will the crossover sections be separate or joined?"
"here is a pic of the underside and where ideally I would like the shim to be...hopefully this will help make sense of my explanation. For some reason I cant get my head around the implication of the shim meeting in the middle point and how that…"
Hope you don't mind but could I pick your brains on something?
Im working on aanother silicone sculpture now - (see attached photo - its a miniature rough shape of what im planning on making).
My question is how would I best…"
"Wow! It's huge and fairly disgusting (which is a compliment!) I didn't realise it was on that scale. Looks really excellent. I used to do a lot of prosthetics for Television (Casualty in particular) back in the days when we used gelatine.…"
"Thanks so much Simon - I have opted for just covering the base in several layers of appropriately coloured silicone. I had a good think and the sculpt was never sposed to stand up anyway. It was designed to be suspended - held from its top. I have…"
"Yes! Definately getting somewhere now - have managed to patch up some nasty seams and both seperate parts are now solidly attached!
Im thinking it was down to errors in measuring A & B as the amounts I was mixing up were very small - as you…"
"I don't measure it at all, just chuck in enough to thin the silicone down to what I need. It evaporates pretty quickly, so you may find you need to add a bit more to get it to flow.
I imagine the amounts will be pretty similar for the 2 types,…"
Sorry - I have one more question. I am using platsil Gel 25 to paint the sculpture (withthe lighter fluid you recommended & silicone pigments). Do you know if the ratio for silicone to lighter fluid is the same for Gel 25 as it is for…"
Have managed to get the attachment as close as possible to the original colour so i'm going to join the two pieces today and try and bridge the slight gap with colour washes.
Thanks for your help and advice on this.
"Got it. The foam colour is affecting the surface colour, so your silicone is fairly translucent. So you will have to do some clever surface colouring if they come out a bit different. It is one of those things that's just awkward. But mixing…"
"What I do is mix up some silicone with maximum retarder and then thin it with lighter fluid, then add colour to paint. You don't need to make up a big quantity, in fact it's best to keep to very small batches in case it starts to…"
"p.s: do you ave any recommendations for what to use to thin down platsil gel 25 for painting colour onto the model? Solvent thinner is the popular one as is naptha but I was wondering if there was a cheaper equivelent like lighter fluid for…"
I recast the end of the trunk today - spent a long time matching the colour of the existing torso very precisely - but came out lighter .
Now the main torso is two layers of platsil gel 25 - one painted on - the other sloshed…"
