INTRODUCTION Tool Features: • FasGroov Tool identification incorporates both the numbering system of fabrication machines and the traditional hand tool color coding system. FasGroov Tools are available for both shiplap and vee-groove fabrication methods. • Easy, turn-the-knob, blade height adjustment. Scrap lifts cleanly out of groove. Blades are also easily removed without removing screws.
Easy one-piece layout: • Use #6 Tool to shorten length of duct section, by measuring from outside edge of material to be scrapped. FasGroov Square permits fast and accurate layout without marking cuts or calculating add-on dimensions. Lay out ductboard as you cut. Simply align dimension on FasGroov Square with edge of previous cut and move across the board. Square is also easily adjustable for angled cuts.
For right or left hand use: • Right hand orientation of 1” kits is easily changed by converting #5 Tool and FasGroov Square for left hand fabrication. Tool handles may also be turned around to provide left hand grip angle. SETTING UP TOOL Adjusting Fasgroov Square PREDETERMINED SETTINGS Place adjustment knob into hole corresponding to most used angles. OTHER ANGLES Right hand operation. Left hand operation. Place adjustment screw into protractor adjustment slot and tighten at desired angle.
Hand Tool blade height adjustment: #1 TOOL FASGROOV #1 TOOL 1/2” Push the FasGroov #1 Tool along the left edge of a test piece of ductboard. Measure the depth of cut of the female shiplap groove, it should be half the thickness of the ductboard (see illustration). If adjustment is needed: (1) Turn the blade adjustment knob counterclockwise to lower the blade for a deeper cut or (2) Turn the blade adjustment knob clockwise to raise the blade for a shallower cut.
#5 VEE VEE VEE #5 FASGROOV-VEE TOOL FASGROOV #5 TOOL Push the FasGroov-Vee Tool through a test piece of ductboard. Push the FasGroov #Tool through a test piece of ductboard. Measure the amount of fiberglass remaining between the foil backing and the deepest part of the vee-groove cut. There should be 1/8” of fiberglass remaining (see illustration for width of cut.) The blade should cut deep enough to skin all of the fiberglass off the foil backing.
Blade removal, replacement: Since the blade adjustment mechanism is the same for all FasGroov Tools, this procedure applies to any tool requiring blade removal/ replacement. BLACK PLASTIC SUPPORT Blades remove without removing screws. BLADE ASSEMBLY SCREWS Loosen Screws Slide and remove worn blade assembly. Place new blade into the black plastic support and retighten screws. Note: Initial cutting friction may be realized due to rust prevention factory finish on the blade. 8 w w w .
SHIPLAP FABRICATION W1 H1 #1 GRAY #2/4 DARK ORANGE W2 #3 ORANGE H2 #2/4 DARK ORANGE #5 BLUE CUT FLAP Face the factory made female shiplap edge of a ductboard section. Place the FasGroov #1 Tool against the left edge of the ductboard. Push the FasGroov #1 Tool closely along the left edge to produce a female shiplap groove. #1 TOOL #2/4 TOOL Set the FasGroov Square on top of the ductboard. Place the ruled edge along the factory made female shiplap edge.
Place the FasGroov #3 Tool against the slide edge and push along to produce a left hand shiplap groove. Move the FasGroov Square to the right and measure the desired inside duct width dimension (W2). Align with the right edge of cut previously made by the FasGroov #3 Tool. Place the FasGroov #2/4 Tool against the slide edge and push along to produce a second right hand shiplap groove. Place the FasGroov Duct Knife on the right edge of cut previously made by the FasGroov #5 Tool.
VEE-GROOV FABRICATION W1 H1 #1 GRAY #2/4 DARK ORANGE W2 #3 ORANGE H2 #2/4 DARK ORANGE #5 BLUE CUT FLAP Face the factory made female shiplap edge of a standard four foot ductboard section. Place the FasGroov #1 Tool against the left edge of the ductboard. Push the FasGroov #1 Tool closely along the left edge to produce a female shiplap groove. #1 TOOL VEE TOOL Set the FasGroov Square on top of the ductboard. Place the ruled edge along the factory made female shiplap edge.
Place the FasGroov-Vee Tool against the slide edge and push along to produce another vee groove. Move the FasGroov Square to the right and measure the desired inside duct width dimension (W2). Align dimension with the right edge of vee groove made in the previous step. Place the FasGroov-Vee Tool against the slide edge and push along to produce a third vee groove. Move the FasGroov Square to the right ,one last time and measure the desired inside duct height dimension (H2).
