The boiler hand holes in the kit for the J15 are a bit of a work of fiction and so I spent a couple of hours doing these last night with some wire and small bore tube. In the cold light of day they were okay but really didn't pass for me. Then remembered I had some of LG's NE cast offerings. A bit of time cleaning up, changing the shape and trying to get the flat section as thin as possible got to this stage. A lot better... Still not quite right as they should be flush with the boiler cladding but... JB.
