Hi Anthony
What sort of models are you interested in? – static models, R/C, sailing, fast electric ?
The basic tools are always the same though later as you mention you will want to diversify.
Thinking about the toolsI use the most, I’ve whittled it down to a fairly basic list .I’ve made models with ONLY these, though other listers will probably augment the list.
My most used tool: a good cutting knife – I use one that holds Stanley blades and change them often! Second a STEEL ruler and a cutting mat. This takes care of straight cuts – I’ve cut up to 4mm plywood with this method though that is rather a chore! My Stanley knife is my number one implement1
Curved cuts – fretsaw with a fretsaw stand. I used this for years, though now I’ve gotten lazy and bought an electric scroll saw.
A variety of clamps, clothespegs, plastic clamps, metal etc etc
I work mostly in wood, so use ordinary white wood glue. Plastic obviously would require different glues.
A variety of sandpaper and sandpaper blocks – I like those hard rubber blocks that one can secure the paper to.
A small rigid saw with a mitre block (optional)
A small hand drill and various small drill bits.
Later on you will need paint, varnishes etc etc.
Those to me are the implements I would have with me on a desert isle! I’m sure other listers will add to this!
Hope this helps
Pierre
