Making a mould of a timber railing.

Question:
I am wanting to make molds of timber railings and posts to make concrete versions. Can you suggest what items are best to use? Please include items required for sealing timber if required.

Answer:
We recommend that you use Latex #72 rubber for your particular item as the detail isn't very intricate. If your item was intricately detailed we'd suggest using Latex #70. We recommend that you seal the original wooden item with Craft Seal. You will find both items on our web site but do not hesitate to contact us again if you need further information. All the best Joseph

What materials to use to make Model plane parts?

Question:
I'm interested in turning out small quantities of model plane parts ( missiles, bombs, nose spinners, wheels, pilots etc..) that will be using a sample machined/finished in pine wood ( or similar).... These items will range from very small to about 5 cm x 2 cm.
Can you advise me on what product would be best for me to have a go at it? The moulded items might be precoloured and/or hand painted afterwards.
Thank you

Answer:
Use CraftSil silicone for the mould and CraftCast polyurethane resin for casting into the mould for the finished part and you will get perfect parts that can bne painted, sanded drilled etc. We have some information in our web site Tech Tips on this subject and will be releasing a kit later this year.
Craftsil Can be found in our store by clicking here
CraftCast can be found by clicking here

My Crystal Cast Epoxy Resin Doesn't Set.

Question:

Hi,I purchased some Crystal Cast Epoxy Resin last year, Tuesday 10th April 2007 and it has worked great on two occasions.I have just opened the bottles and used the formula as always but the resin has not set?I used 50/50 mix and stirred for 2 minutes but it has stayed tacky after 2 days?Can you advise, is the product out of date?Can you supply something I can spray on the surface to harden the liquid on the surface?

Kindest regards, waiting in anticipation.

Answer:
Although the shelf life after opening is 6 months sometimes we get good results for much longer periods it all depends on how it is stored. Cool dark places are best. There is nothing you can spray on to assist hardening but you might try gentle heat. We use an oil heater and place items on top that we are having difficulty with., No guarantees but you might save it. All the best.

Release agents for use with Polypropylene Moulds.

Question:
Hello,Do you sell the mould release/condioner for use with clear casting epoxy and polypropelene moulds please? Thanks


Answer:
Silicone moulds usually do not require a release agent with epoxy resin but polypropylene moulds do. We would use a wax first then PVA release. We use J Wax aerosol but this cannot be posted only sent by courier but you can use Johnsons Paste Wax available from some hardware stores. The PVA is listed in our shopping cart.
