Tips & Tricks 3: Filling Ejector Pin marks easy
I like many have groaned when on the inside of every hatch , specially it seems with Tamiya , there is a filthy great series of ejector pin marks !
Well the tool makers add these to the mould to help extract the plastic from the mould in the manufacturing process . Key words ?????? tool makers The pin marks are a regular sizing that the tool maker added , how does this help us ?
The Historex Punch & Die set

The pins are the same size as the dies in a punch and die set sooo just add discs to the pin marks
, carry different thicknesses (or multi ply) for different circumstances , as most modellers know , it is easier to sand an "outy" pin mark than fill an "inny" pin mark .
I hope this helps !

I just want a decent punch and die set. I've attempted to make one with the help of some of our friends here but failed. Drilling the hole is no problem the punch has alluded me.
