Ingredients
a- A bottle of trichloroethylene (it can be found at supermarkets in the stain-removers dept. or at art craft stores)
b- a candle
c- a lighter (or matches - to lit the candle)
d- liquid glue (the thin one with brush applicator)
e- a knife
f- a few pieces of scrap sprue
g- a pair of tweezers
How to
Step 1
Lit the candle and warm up the sprue and then stretch it to the desired diameter

Stretching the sprue
Step 2
Cut a piece of stretched sprue to match the length of the weld seam you have to reproduce
Step 3
Apply the liquid glue on the model where the weld seam has to be done
Step 4
With the tweezers carefully position the piece of stretched sprue where you applied the glue, press it in place and let it rest for a few minutes


The sprue has been positioned
Step 5
Dip the brush in the trichloroethylene and brush it on the piece of stretched sprue. Repeat the process until the plastic is soft enough, usually two to three passes depending on the weld seam thickness
Step 6
Tap the knife on the stretched sprue until you get the desired effect. In case you need just apply more trichloroethylene and continue tapping
If the effect is too rough, just apply some more trichloroethylene on the weld seam to smooth it down
