DIY SPs - Tutorial #1 Making 1 sided molds

Post by anselmo » Mon Oct 19, 2009 7:19 am

Lureandmore.com Tutorial 1
Making 1-sided molds

Pouring your own Soft Plastic fishing lures is cheap, easy and safe. It is also the perfect way to make truly custom lures for yourself and your friends (and even for sale).
01 - what you need_rs.JPG


What you need (left to right)
Back Row

1) Super glue – for attaching the bait to the mold box.
2) Room Temperature Vulcanising (RTV) Silicon – This will be the mold itself. Other options for the mold are Plaster of Paris (POP), household silicon sealant or aluminium. RTV is relatively cheap, safe to use at home, and produces molds that are ready in 3-5 hours without further steps, can be used thousands of times with a variety of products (resin, plastic, lead) without sticking, can be warmed in the microwave and don’t break if you drop them. POP is also easy, but requires sealing with epoxy and slow baking to finalise tempering. Household silicon can be used by squeezing it out and mixing it with a small amount of water and colouring (so you can see how well mixed the water is). Aluminium molds will be made to order by professionals. RTV is unique in that once cured, it ticks only to itself, meaning you can pull away lures, masters and mold boxes with minimal effort. RTV can be bought in hobby stores or on the Internet.
3) Mold box – I got mine at a hobby store.
4) Disposable cup – for mixing RTV.

Front Row

1) Masters – baits to copy. Here I’m using a Megabass Giant (French) X-Layer, but any bait with a flat side will work (slug-go etc). Remember if you’re going to sell baits, copying someone else’s design for profit breaches copyright laws. I neither advocate nor encourage this.
2) Metal skewer – for stirring the RTV.
3) Paintbrush – for initial layer of RTV on master.
4) Scales – for accurately measuring RTV by weight.

Steps

1) Test your master for size in your mold box. Note the colour variation between these 3 baits even though they were all taken from the same pack, also the flashing around the head of the middle bait.
02 - test for size_rs.JPG
2) Wash your masters in warm soapy water then dry thoroughly. This is to remove oil and salt so the maters stick to the mold box.
03 - wash_rs.JPG


3) Glue the master to the bottom of the mold box

4) After allowing the glue 10 minutes to dry, turn the box upside down to check it’s holding the lures in place

5) Weigh and mix the RTV according to the instructions. Ensure you pop any bubbles that appear.

09 - add catalyst_rs.JPG
10 - mix_rs.JPG
11 - pop bubbles_rs.JPG
6) Paint a thin layer of RTV over the masters. This is to ensure full coverage without any air bubbles.
12 - paint layer_rs.JPG
13 - painted_rs.JPG
7) Pour the rest of the RTV over the lures. I suggest pouring from one side to the other – this ensures any air bubbles are pushed away from the lures, keeping the integrity of the layer painted on.
14 - poured_rs.JPG
8) Check underneath. Some creepage under the masters is to be expected. The final mold will be trimmed with scissors anyway (another advantage of RTV).

9) Wait 24 hours. Although the RTV sets in 3-5 hours giving it a full 24 hours minimises tearing when removing from the mold box.

10) Remove the mold from the mold box.

11) Remove the masters by gently bending the mold, and trim the small overhangs with a pair of sharp scissors. You now have a mold ready to pour perfect copies of your masters.

In Tutorial 2 I will show you how to pour a replica of your master using your new mold

"anselmo" - Great 'Tutorial' and really clear pics, thanks for posting this- I do appreciate how much work you have put in here. These type of 'Tutes' are really big O/S and am surprised they (making your own) have not taken off here, especially when you look at the price of 'Starlos' and Co's offerings (& a lot of others).
Looking forward to seeing the 'Pours'.pete

Love it Nick
Couple of ???
What stops the lures sticking to the bottom of the container seen as though you super glued them down.....wouldnt they tear as you pulled it out.

Also because of the way this is done it appears you are left with a flat surface on the bottom and when you pour the goo in it will be flat also.......what can you do if you are trying to get a fully rounded lure made up.
