HI
about the cab builing there is a lot to be told, but actually it's easy when you know your way around is.
ther is just one thing most modelbuilders hate to do. ant that's to throw away the thing they put so many ours in.
but if you want to have a perfect mold. there is a risk that the cab you made is coming out the mold in small peices. I don't use babypowder of siliconspray to have an easy release. everything on the surface of the cab (prototype) will eventually end up in the mold. and the resin cab.
painting over babypowder of siliconenspray isn't easy.
a truck I made for the DAF museum in eindhoven. for kids to experiense airflow on a scale truck is shown here, is't in dutch. but the pictures will tell it all I hope.
