The 2 in 1 fat boy scriber is a tool for fitting doors as well as a general scribing tool.
It is exactly the same size as the standard fat boy but with the ability to hold the body higher in the cradle.
In door fitting mode a 0.5mm stainless steel plate is bolted to the front of the scriber.
Once the door is reduced in size so that it fits in the frame and there is at least a 0.5mm gap, the plate fits between the door frame and the door and slides along the door frame marking a line on the door at a given distance away from the frame.
Plane down to the line and the door should fit with an even gap on all 4 sides.
When in scriber mode the plate is removed. You can use the marking wheel holder to score a line to work to. Work accurately to the line and your scribe should be just about perfect!
Go to the marking wheel holder page to see the holder in scribing action in a big boy scriber and how using masking tape gives you a clear line to cut to.
Great on cross grain work but it works equally well on mdf and along the grain on solid.
The 2 in 1 fat boy scriber holds the 12mm Quangsheng cutter which fits the Quangsheng marking gauge.
Replacement cutters are available at www.workshopheaven.com and other online tool stores.
