Hi Tin,
I scored some brownie points with R a couple of weeks ago. We've been in our house for 4 years & the builder didn't finish the door jam lock pockets ( hope that make sense, the hole that the latch goes into) he drilled the holes & put the plate on, job done....yeah right! So after spending 1/2 a day caving out a rectangular hole in a bit of 10 mm plate for the die, cutting bits off the sides of some 19 mm square putting some bolts thru so it all stayed lined up, adjusting things to allow for material thickness it was done. Found a bit of 0.9mm stainless marked it up, cut on the bandsaw, carefully lined up in the die & squashed up in the vice, remove the press bit file to size, push out. Looks a million buck, only took an hour to make the 15 I needed! Tried to buy plastic ones but nobody had our size, the lady in the shop commented "oh they come with the door locks, the builders don't bother putting them in"
Cheers Kerrin
