Hi Guys, be nice as this will be my first post on here.
I am a keen user of magnets in all my models and having just compleated my own Predator for my Dark Angels 4th Company.
I decided to try to save time and simplify construction, the quantity and size of magnets required and with a minimum skill level for the modeller.
I will try to keep in a logical sequence for the explanation but if you have any questions just ask and I will add it to the tutorial.
To begin with you will need:
1. Rare earth magnets (easily available on various websites)
10 x 2mm x 2mm
2 x 7mm x 2mm
2. Metal plates approximate sizes only (I used my old snap off hobby knife blades) about 1mm thick.
4 x 7mm x 12mm (Doors)
2 x 5mm x 10mm (main weapons)
3. Drill and 2mm drill bit. (I use an electric hobby drill with multiple speed set on slow)
4. Super glue and plastic glue
Assemble the hull sides as per the instructions and simply remove the rivet from the middle of the door to allow a flush fit for the magnet then glue it down with super glue, the polarity does not matter. I have glued the magnet to the outer side of the hull as this allows me to fully detail the vehicle interior.
I will split this down into sub assemblies.
Glue the door and the sponson attachment together and allow to dry.
Using super glue fix the larger metal plate centrally to the rear of each door. At the same time you can do the same thing to the rear of the standard doors using a piece of sprue to allow for the extra distance of the magnet. This will allow you to convert your Predator to a Rhino later if required.
Sponson Hangers (correct name anyone?)
First use a sharp model knife to trim off the lugs at the base of the hanger then drill a hole to fit the small magnet.
Super glue the magnet in. I have reversed the polarity on each side so only the correct weapon fits on the correct side but this is optional.
The Heavy bolters
You will need to increase the size of the gap at the top of the Heavy bolter slightly to allow the magnet to fit through when the two halves are together. Then glue one of the small magnets into the existing hole on the outer part of the Heavy bolter. The best way is to get the hanger and allow another magnet to attach to it as this will ensure the correct polarity. Offer the hanger up to the Bolter remembering that the cut out goes to the front. Keeping the glue away from the hanger and wait for about 10 seconds until the glue sets on the bolter and remove the hanger. You can then backfill any gaps with the super glue.
Follow the same procedure as above but you do not need to increase the size of the gap at the top. Make sure that the polarity is correct before using glue.
You should end up with this.
When you come to fit the sponson to the hanger simply slide the hanger into the slit at the top. The magnet will self-centre and make a firm lock but it will still allow the gun to pivot up and down.
Again I have split this into sub-assemblies.
First glue together the autocannon and lascannon. Then the rear turret bin and lascannon battery. While you are waiting for this to dry you can work on the two halves of the turret.
Using 2 stright sections of sprue approximately 25mm long:
The sprue is shaped like a flat topped triangle. You will need to glue one piece wide edge forward and the other reversed to allow the triangles to fit flushly when the two turret halves are brought together (see the picture). These are glued using the pivot uprights as the attachment point. Test fit the two halves together whilst the glue is drying to get the placement just right and allow to dry overnight.
Once dry you can then drill a hole for a small magnet in the centre of the sprue. Easiest is to again fit the two haves together and use clamps to hold it while you drill the hole. The hole should be mostly in one of the 2 sprue sections and you can then glue the magnet flush and again the polarity does not matter.
The turret is also drilled and fitted with a small magnet at the rear between the locating lugs for the bins.
The bin and Lascannon Battery
Drill a hole between the 2 locating lugs and glue a magnet in each hole remember to check the polarity.
Cut off the 2 studs from either side of each gun. Sand about 2mm off the rear of the gun making sure that the sanded section remains square as this will show up later as drooping or raising of the guns line of fire. Then using super glue fit 1 of the small metal plates to each gun and test to make sure of a correct fit.
You should end up with the following - a fully interchangable turret.
I have just finished a Rhino/Whirlwind model (later in this thread) and found that the various remaining hatches and the turret do not require magnetisation to the hull as they fit snuggly.

I hope this helps others, any questions just ask and I will be happy to help.
