  • Badger Air-Brush Co. website 
     This is the official Badger Air-Bursh Co. website. It provides on info on the company and its excellent products, plus a lot of extra info. The New Products section intros new products, and there is other very useful airbrush related information.
  • Modelling Glue General : Revell Contacta Professional is a liquid glue with a long needle applicator, which has served me brilliantly since I really got back into modelling in 1996-1998 period.  I have bought four of these in this time, and only recently (end of 2002) finished the first one!  You will need a thin piece of fuse wire, to help unclog blocks in the applicator otherwise you will be frustrated by the need to replace these glues constantly when you have only half finished them!.  For tube glue, I use Humbrol poly cement, which is still my actual favourite hobby glue

  • Modelling Glue Tube Variety : I find that tube glue is often best for limited run types of kits and seems to have better adhesion for these.  I have always used Humbrol Poly Cement, which is still my favourite glue overall.  I apply it with a toothpick so I don't apply too much and have also used it to fill small gaps (but remember that glue melts plastic so be careful).

  • Superglue : to attach metal and resin parts, use a fast setting and strong bonding type, I use Zap CA with a toothpick, although I find this solidifies a bit in cold weather so am having to replace annually.

    (Exacto, Excel) : cutting and trimming, very sharp - use slowly and with care

  • Tweezers : small and handy and invest in curved and straight tweezers to ease specific jobs. I have two main tweezers (a small and large one) for various uses.

  • Thinner/Brush Cleaner : Used to clean brushes after painting.  White spirits like Turpentine works the best for me, but wears out brushes.   

  • Paint : I use Humbrol super enamels and have 95% of their whole range, choose the brand that suits you, but Humbrol is one of the most accessible brands to cross reference to others.  I also find that Humbrol paints have most colours whereas others (eg: Tamiya) you may need to mix paints together to say get the right RLM mix.

  • Paintbrushes : You need a fairly good range of brushes ranging from finest to larger brush types

  • Toothpicks : See everyday usages below - as an applicator, mixing paint and so forth

  • Leftover sprues : I break up the bits of leftover sprue from the frame of a kit and keep these aside.  They are great for mixing paint, using as "stretched sprue" and so forth

  • End-nippers : Used to cleanly detach parts from the sprue, you can both blunt nose and needle nose, it is probably a good idea to have one of each.  If you can only have one, I use the blunt nose ones on a much larger scale.  

  • Masking Tape : Special low-tack type specifically for modelling like Tamiya - 6mm recommended, I also use 10 mm

  • Putty : Using a toothpick lightly fill gaps and holes on model aircraft, there are several choices, my preferences are Tamiya or Mr.Putty from Gunze Sangyo

  • Sandpaper : Wet'n'dry (so dust is not so prominent) types to smooth out join lines etc - Grits between 300 & 600

  • Flat File : a couple in different 'roughage' to enable one to file down rough features.  I use a triangular and a flat version  

  • Panel line Scriber (optional) : Rescribe panel lines and control surfaces to correct kit errors, or engrave raised lines

  • Mask-solution (optional) : a special solution to mask off canopies like Gunze's Mr Masksol, Humbrol Masksol etc

  • Clear Part adhesive (optional) : Hobby glue and super glue fogs up clear parts when you attach them to plastic, unless you are very careful.  PVA, White glue and those sorts are good alternatives for fixing clear parts, and Humbrol sell a product call "Clearfix" for this reason too.  I have always used hobby glue because it is my preference, and I manage to affix without any problems  

  • Decal Setting Solutions (optional) : There are several setting solutions on the market to help with the adhesion of decals.  Decals generally go onto a gloss surface without any real need for setting solutions, but I have found that their purchase is necessary and they do aid in the adhesion, and preventing "silvering" and other effects.  There are heaps of options available from the two application Micro Set and Micro Sol solutions, to Humbrol Decalfix which you apply under and on top of the decal.  My preference is Gunze Sangyo's Mr.Mark Softer which seems to work well.  

  • Varnishes (optional) : These are necessary nowadays to protect the finish of your model as well as other things like decals, and to get the right sheen on your model.  I use Testors Gloss Laquer, and Humbrol cotes for Satin and Matt finishes.

  • FASTENER TIPS  
    NYLON BOLT INSERTION

    If you ever have had trouble getting nylon bolts started when attaching the wing or other major subassembly, try this. Bevel the threaded end of the bolt so it will tend to be self centering when you're trying to get it started. The easiest way to bevel the bolts
  • Drill Tips
     
    SERVO HOLES
     
    When trying to install a servo in a plane, try this idea. Often, the cramped quarters doesn't leave enough room for a standard size drill. Use a standard Exacto handle with a 1/16" drill bit installed. The pilot hole can now be drilled by turning the handle and will make an acceptable hole for the servo mounting screw.

     
    XACTO HOLDER
     
    Try drilling a hole in the handle end of your small Xacto knife holder. Thread a key ring into this hole. Now you have a knife that won't roll off the work bench and has a built in hanger, as well.

     
    CASE HARDNER
     After cutting threads in wood with a tap (for wing hold down bolts, for example) saturate the hole with thin CA to "case harden" the threads. You will have to run the tap through one more time after the CA sets to clean up the threads. The threads will now last longer than the airframe.

  •   DRILLING TIPS 

    Drilling for Dowel Pins
    When drilling holes in the plywood of your plane to accommodate wing hold down dowel pins, it is sometimes difficult to get them just the right size without some slop in the hole. For example, if you were using 1/4 inch dowel pins you would need to use the next size larger drill bit which is normally 17/64. Not bad but a better way is to drill the 1/4 inch hole, harden the hole with CA and then enlarge it with a 1/4 inch prop reamer available from Tower Hobbies. This makes the hole just the right size and a snug fitting dowel pin. This prop reamer works with other sizes also.
