Unlike their HO scale cousins, O scale resin kits do not have preformed grabs included in the boxes. So we have to bend our own. The same issue can arise on cars with special grab widths or styles. The half grab comes to mind.
I have 2 super simple tools to assist me in this task. I don't take credit for them, but share them as they were shared with me.
The first was from Ted Culotta.
Drop grabs present an additional wrinkle. Need to have all those bends the same.
2 down, 34 to go. Slightly tedious but the end results are worth it.
