If you have over sized pictures or paintings and you don't want to spend a million to have them professionally framed, this instructable is for you.
It would save you quite a bit even if your pictures aren't that much oddly sized or you have some 4mm masonite boards to recycle...
Step 1: Marking
Measure 2.5 cm from the margin (distance depends on the clip model you have at disposal), where you wish to have your framing clips.
Step 2: Get Your "Dremel Work Station" or Anything Else Similar
Set the inclination on 45°
Step 3: Grooving
Get your silicon carbide or diamond blade bit and set the machine on about 3/4 maximum speed,
Lowering the shaft through the lever, and sliding slowly the board, make a straight groove into the masonite backing panel; don't cut too deep....
Step 4: Groved
It could look even better than this...it depends on your handy skills.
Step 5: Clip!
Cut either glass or perspex to the sizes you need and...clip everything together!
Should the clip result a bit loose, bend it a bit by hand and re clip it.
Step 6: Enjoy
