When I first began WW the coloured hard wax filler sticks and the beaumontage were used a bit to cover up my errors – a raggy join, unfortunate ding or glaring tear out hole. As I improved with the machine tools, these items went into a tin and have not been used in years.
However, now I am larnin’ hand tools so the joints and surfaces are once more in need of a little fix from time to time. I hope to get better with hand tool practice, as I did with the machine tools, so the magic error-hiding goos can be put away again. Until then…
Does anyone have extensive experience with “fillers” such as these? I would like to understand the best techniques for using them, as my previous efforts were trial & error; no book I have containing much about their use.
I always struggled with heating beaumontage up and applying it efficiently. Is there a special tool – a variable temperature soldering iron or similar – that is worth getting?
Lastly – how much waxin’ and such is allowable, do you think, before the point where one should just make another rail or whatever?

Lataxe,
If you want to stick with tradition then just light the end of the beaumontage and drip it into the place you want filled. Then you can level with a sharp chisel when hard. Of course this is traditional and not the way I do it.
I use a hot knife with different tips to heat small bits then fill the holes,cracks or whatever and level with the same tool.
I also use burn in balm around the spot to help remove excess beaumontage.
Also a small piece of cloth wrapped around a flat piece of wood and dipped into lacquer thinner helps to finish levelling smooth the repair.
Typically I wipe the burn in balm around the repair area. Then use the knife to burn in the beaumontage. Then I will use a sharp chisel to get the repair mostly level, then use the burn in knife to smooth and level the repair. Finally I use the cloth wrapped wood and lacquer thinner to smooth the area and fully blend the repair.
I am sure there are lots of other ways to do it, but this is how I am comfortable using the material and the repairs are quite satisfactory.
I have attached a couple of links to suppliers of hot knives and other materials.
Lastly you could just use a hot plate and some small metal painters spatulas. It just depends on how much you want to spend on a system. The oven and spatula ststem is nice but pricey. The electric hot knives take a little getting used to, but once mastered, they are just as efficient.

It's my understanding that beaumontage is more wax-based than the resin-based stuff we use here. Konig has a series of hard-wax fillers, though and it's starting to become more used here.
I use resin ("hard" or "traditional") sticks, newer "soft-melt" sticks, and rarely "low heat" (waxy) sticks. Traditional are shiner and harder, soft melt are softer, lower sheen, and will not shatter (so they're good for edges and feet). I use an electric burn-in knife, but tradition uses knives heated over a sootless alcohol "stove."
Here is some information on basic "burn-in" procedures:

Watch the video and do a couple hundred practice repairs and you will have it.
(Is this what you're asking about??)

Thank you both for the information and for the links.
I have learnt from you that there is something called burn-in balm, which I'll get; and at lest two ways to melt/shape the goo. Also, the use of lacquer thinners is something I was unaware of.
I found a pack of 5 small artists pallete knives in a local shop for a mere £6 ($12). I'll try these with a Trangia meths stove burner, as there is one in the loft from camping days and I think that flame is sootless. I have meths for use with french polishing.
The hot knife option looks more controllable than a flame and not too expensive. Am I right to assume that a "cool" hot knife burner is the one for beaumontage and other wax-based fillers? That is, a knife with temperature control from about 80 - 250 degrees F?
The wax-based fillers I have are Liberon - their 24 colours of bees/carnuba wax filler sticks and their beaumontage tin of ten "sealing wax" sticks. When last employed, a few years ago, I used an old cheese knife heated by a hot air gun or blow torch - not exactly an efficient way to go!
Thank you once more for the info supplied and the pointers to more.
