Every year or so someone at the local club asks how I make my "welds" and I do a little demo at the next meeting. This last time I took the camera and wonderful little assistant took the following photos. Since I did the last demo with this ARV project I'll add it to the progress.
I find this the easiest for me right now. Before I would mix up some A+B putty, roll it out and work it in with a knife, trim work it in and so on. A couple issues I had doing that way was drying time, most of the welds looked big and heavy, that more than half the putty would start to harden before I could use it all up, and most frustrating was that at times the dried putty would break loose and fall off the model. As of now I'm using strip/rod styrene and stretched sprue.
1) You need 3 things, a kit, some strip/rod styrene and/or stretched sprue, last a bottle of liquid cement. I prefer Testors for this as I feel it does not evaporate as fast.
2) Dip the end of the styrene choice into the glue and I hold it in there for approximately 30 seconds. Just enough to get the styrene good and soft. This will very the thickness of the styrene you are using.
3) Then place the softened styrene on to where you want the weld, I can't work fast enough to do more than approximately a half inch at a time.
4) Work the softened styrene with the end of a tool, I use a number 11 knife, I just press down making little indentations on the styrene rod/strip until I feel that it looks like a weld
5) Trim off the rod and then start the process over
Somethings I have found out that I really like about this is, if you do not like the weld it files/sands off easy and they stay put.
