johnyrotten Posted January 26 Posted January 26 Think I figured out a simple way to pull this off. The welds look like an old farm repair,stick welded,perfect for my build. You'll need an old Xacto blade, bent on tip and dull. This is important. I lightly ground the area to be patched with a burr. Cut the patch out of styrene, the thinner the better and use solvent glue to secure it. After it dries, reapply a swipe of solvent around the edge and use that bent blade to just knick the edge, at a 45 degree angle to the patch. Barely nip it off, it'll be soft enough to form the weld bead, don't try and finesse it, just chop along the edge. Should look like this. From here it's just a matter of washes, dry brushing ect. Here's mine, still have to go back and dry brush a bit of steel to bring out the welds. Here's what i tried to mimic with this. 7
Ace-Garageguy Posted January 26 Posted January 26 Looks really good. Just a thought...I've often seen step-plate (diamond-plate, tread-plate) that was WAY too heavy to be appropriate used to repair vehicle cockpit and bed floors too. Detail Master makes it in PE for 1/24-1/25, as do some others, and there's plastic sheet available as well. 2

This was .010, still a bit heavy, but I worked with what I've got. Thanks 1
NOBLNG Posted January 26 Posted January 26 Nice technique. What if you didn’t even use a patch? Just brush some solvent cement on the area to soften the styrene first. 1

The whole point is to represent the "technique" chimps have been using since cars and stick-welders existed...slap a way-too-thick patch over a rust hole, secured by bubblegum "welds".

I had thought about using some .020 rod and doing similar, its easy for me to get carried away doing this kinda stuff. I did notice the solvent makes the styrene sloppy very fast if you go overboard. Luckily it evaporates just as fast.
Beans Posted January 27 Posted January 27 Very nice patching. I tried to do this only once. Used a very small hole punch at an angle to make the weld lines. It worked pretty well to keep the round pattern. 1

I think a nice even bead would way more difficult to reproduce at this scale, not to mention color and shade. I'll have to give it a try

I think I actually made a long thin round strip of putty and made the weld as a totally separate piece because I was just adding a welded seam to a flat part and not adding the patch. I like the way yours came out. The patch is cool and authentic.
Ace-Garageguy Posted January 27 Posted January 27 You guys may or may not know that very nice weld-beads are available as "decals", 3D resin parts on decal film with adhesive backing. These went away for a while, but appear to be back in production...along with rivets and other stuff. https://www.archertransfers.com/collections/welds
