SEE BELOW NEW INFO FOR RAPID SETTING OF SUPERFLEX MK2 VERSION: You can now choose to allow Cold curing or speed up the operation and hot cure.


Kit Details and basic instructions: These are in the sequence to follow, Mould release, Prepare Jighooks and fit, Measure and mix, Add colour, Add catalyst and mix, Fill moulds, Scrape off, Clean up after demould 2-2.5hrs at room temperature.

Advice: Don't try too complicated colour mixes to start with for your first moulds, make your first ones until you get the basics by just using the Superflex out of the can No colours or jigheads just cast plain lures. The standard colour still take good fish so you won't be wasting the lures, once you have mastered the basics then move through to creating more advanced lures adding colours and moulding in jigheads.

Items In Kit: 6 small paper cups
6 spatulas
1/2" soft mould brush
Spatula set

Moulds: As supplied

How to workout what amount of SuperFlex you need per mould, visit the moulds page HERE find the moulds you have purchased and click the thumb to visit the mould info page. On the mould image you will see the following info : The Weight of the mould in grams and under that the weight of the lure in grams. The lure weight is the amount of Superflex liquid you need + 10% to allow for waste that is left in the mixing cup. E.G. SKINNY MINNOW MOULD  mould = 178grams the lure weight = 15grams x 10% = 16.5g so round it up to 17grams, the amount of catalyst @ 20-1 would fraction below 1ml on the syringe. This image shows were the details are available.

Jigheads: As supplied

Small container release oil 50ml size bottle: Only need small amount so squeeze enough just to load the brush supplied and sparingly coat the moulds top and in the cavities making sure ALL !! areas are covered this is important especially new moulds as the silicone will stick the lures in the moulds and will tear them trying to get them out. Best to lightly coat the moulds and look at them at various angles to see the shiny coating.

Length of wire for jig hooks: Aluminium wire to wrap around the jig hook shaft to secure it in the Superflex see this image click to enlarge.

Chunk of modelling clay: Used for securing the jigheads in the mould, push the jighead tight against the mould cavity collar and press the clay into place around it and you can adjust the Jighooks to centre them and make sure the gape isn't down in the mould. The clay is re-usable but don't heat it as it's thermo setting and goes solid, if it's stiff just roll it around in your hands body heat will soften it.

500g of Superflex with catalyst: Mix instructions are on the two bottles, using scales weigh in grams the Superflex silicone, if you go to the moulds page the weights of each lure are given. The catalyst, pour small amount into one of the plastic beakers and use syringe to apply and measure the catalyst. Example 20grams SuperFlex = 1ml on the syringe = pot life around 30minutes and de-mould at room temperature approx 2.5hours but check pot contents before pulling lures to see if they're ready to pull. Best to wear safety glasses as the catalyst can squirt back from the syringe pressure or put cloth over top of cup as you squeeze syringe.

Mixing the Superflex in paper cups make sure it's thoroughly mixed together so use spatulas to turn it over off sides and the bottom, mixing air into the silicone isn't a problem as it adds buoyancy to the lures.

Adding colour: The Superflex is pearl white in colour so it can form the basis for many combinations like pearl body and red firetails, pearl lower body blue top if you look at the moulds page you will see examples with each mould in the lures they produce. The Superflex accepts colour easily and you only need a very small amount so just try a sample and you will see. Example bubblegum pink with small amounts of Superflex use a cocktail stick or similar and just dip it into the colour tube top and add to Superflex, you can always add more for colour depth but it can't be reduced easily.

Once you have filled the moulds: use the yellow spatulas to scrape off any surplus Superflex so you have clean mould top and once set the lure will come out with no post production cleanup. Were Jighooks are in place just carefully scrape round them so you don't move them.

Hot Curing Superflex MK2: The latest revised version of Superflex MK2 can now be heat cured if you wish to speed up the curing and mould release time from the normal cold curing times. Nothing changes in preparing Superflex, filling the moulds etc. You will need an oven that ideally has a timer and can be set to 70c as the max, all my tests have found 70c to be the optimum and gives the slimmer moulds a set time of around 10 minutes and the thicker moulds average 12/15mins on the first fill until they warm up and then the set time will reduce, it's best to pre-heat the oven ideally turn the oven on just as you start to fill your moulds. You can use a domestic oven providing it can be set to 70c as Superflex produces no fumes and only has a slight odour when being heated. The oven shown is ideal and it's what we used for tests for the DIY user and can be purchased for just over 30 at at any Argos store as it's one of their CookWorks items. Adjust shelves so thinner moulds below and thicker moulds up the top of the oven, make sure the shelves/oven is level so moulds don't slop over, you can also find space in there to put the mixing cups to fast set them for re-use if you plan to turn the moulds over quicker. PLEASE NOTE SUPERFLEX IS NOT SUITABLE FOR HOT CURING IN MICROWAVE OR MICROWAVE/COMBO OVENS.

Cookworks MG18CEB Mini Oven - White. Recommended and available from Argos at low cost plus light and portable.

Cleaning Up: Let everything set and it just peels off the kit and out of the pots, if not using the moulds again for a while then wash the mould in warm soapy water to remove release oil or it will go tacky.

Syringe after use wash and flush through using warm soapy water or the catalyst will crystallise and takes extra time to clean it out before use.

How To Get That Perfect Two Tier Colour Effect.

This is now very easy to achieve with the Superflex MK2 hot or cold cure silicone, prepare your moulds as usual and pre-heat your oven so it's up to temperature 70c. Mix the lower colour and add catalyst, fill your mould cavities to the required level and pop them in the oven for around 5 minutes to allow the mix to gel. While the mould is in the oven prepare your second colour but don't add catalyst until the mould comes out of the oven. Check the base layer has gelled lightly touch the mix with a probe or have a test pot board with some of the mix on to see if it's ready, it should be quite solid if not back into the oven for a few more minutes, timing will be down to cold moulds etc so first go you may have to experiment. Now add catalyst to second layer mix, pour and scrape off for those crisp clean edges, work fast as the moulds will be warm and will set the mix off quickly. Once poured put the moulds back in the oven for final cure it's that easy !

USING SILICONE OIL: All my moulds I design to work with the Superflex Silicone to be both flexible and durable however if you want to build in more action to the lures you can thin the Superflex using my Silicone Oils. But what you must take into account More Flexible = Less Durable so lures are more likely to get their ass's bitten off or get torn off the jigheads if you go overboard in thinning the standard mix. Start with a 10% silicone oil addition and stir it in well with the superflex before adding colours and the catalyst, the maximum I have pushed a lure to is 30% silicon oil added and that produces a really soft floppy lure. Trial and error is the key until you get what you want to suit your angling needs.
