Simple Scraper IV - Hollowing, Shaping and Finishing Tool (12" length)

With four cutter choices (2 oval and 2 rectangle) suitable for nearly any project or material!

What are the benefits of this tool?

  • The widest and most unique carbide scraper on the market is now available in a longer length for reaching inside hollow forms!
  • When combined with the 17" long foam grip handle, this becomes a beefy 26.5" long tool ideal for great leverage and control.
  • Recommended to use with the flat scraper rest to minimize tool overhang and improve surface finishing.
  • This tool works in the Simple Hollowing System for extended reach vs Simple Scraper I.
  • Beneficial on every project from small pens to large bowls and everything in between because you can shape and finish with a single tool.
  • Quickly remove tool marks and create silky smooth profile transitions between inside and outside curves, as well as straight wave free lines.
  • Makes a perfectly flat bottom with a smooth transition to the inner wall using the oval cutter, or a square inside box corner using the rectangular cutter.
  • Creates a smooth finish with much less tearout and minimal sanding.

Why are there different cutters?

Oval Cutters:

The oval cutter is great for shaping and finishing, combining the usefulness of a square AND round cutter into a single tool. 

  • Oval cutter (for wood): The oval cutters are perfect for virtually any curved shape imaginable especially on the outside of your project.
  • Oval negative rake cutter (for epoxy/resin, hybrid and wood): Like the oval cutter but the negative rake grind also makes this cutter less aggressive. This reduces chipping in very hard materials (epoxy/resin), can reduce tear out in softer materials and provides a great finish in both man-made materials and harder woods. Because the negative rake grind is less aggressive, many people find it easier to use.

Rectangular Cutters:

The rectangular cutters make it simple to create square inside corners, beads and straight lines. Perfect for the inside and outside base of any project. 

  1. Rectangle cutter (for wood)- This cutter shines on the outside of bowls, hollow forms, vases, platers, and wooden pen blanks. You'll also love it for simple spindle work too. Another place you’ll love this cutter is on the inside of a box.

  2. Rectangle negative rake cutter (for epoxy/resin, hybrid and wood)- Like the rectangle insert but the negative rake grind makes this cutter less aggressive. This reduces chipping in very hard materials, can reduce tear out in softer materials and provides a great finish in both man-made materials and harder woods. Because the negative rake grind is less aggressive, many people find it easier to use.

  3. Replacement carbide cutters can be found here

How Do I Use the Simple Scraper?

  • Position the tool rest as close to the work as possible so the carbide cutter is at the lathe center line.
  • Place the tool on the tool rest with the tool shaft parallel with the floor.
  • While securely holding the tool slowly move the carbide cutter into the work.

What are the Details of the Tool?

  • Carbide cutter size: 1.18" x .50" x .10" thick
  • Tool measures 1" wide x 3/8" thick x 12" long. Handle tang is 3/8" square (fits in 1/2" hole) x 2.5" long, so tool length once it's in the handle is 9.5".
  • Handle Options:
    • Best used with INCLUDED Simple Hollowing System & flat scraper rest (sold separately)
    • Fits 1/2" diameter standard tool holder.
    • Tool length when held in tool holder is 9.5"
    • If used with Full Size 17" Handle with Foam Grip - Tool and handle length is 26.5".
    • Tool can be removed from the handle (or hollowing system) by loosening the 2 stainless set screws (wrench included)
    • Does not fit mid size handle. Requires handle with 1/2" dia hole.

Simple Hollowing System

This Hollowing System is especially great for those who want extra help holding tools firmly or need to turn while sitting. Don't let weak or arthritic hands keep you from turning!

  • Stabilize tools while using the laser beam to get precise wall thickness.
  • Fully articulating to get your tool exactly where you want.
  • Use with "Extended Base Plate" for more movement - even the outside of your bowls (sold separately)
  • Combine with the included Simple Scraper IV for deeper scraper hollowing and flat bottom boxes and bowls.
  • We recommend using with the flat box tool rest for additional tool support (sold separately)

Which tools fit the Hollowing System?

  • All full size Simple Woodturning Tools fit the Hollowing System. (Full size tools are identified with tool engraving of SR, STH, SSNH, S90D, S55D or SSCF)
  • The new longer Simple Scraper IV!! (best used with this new flat tool rest!)
  • Use any tool with a 1/2" round handle tang in this system.
  • Mid size tools can be used with the available additional bushing (WATCH VIDEO HERE)
  • 5/8" round tools can be used with the available 5/8" holder

This system comes with the articulating arm, the laser assembly and all the mounting hardware. This bundle comes only with the 12" long Simple Scraper IV carbide tool. You can also use any of our Full Size Tools, or any tool with a 1/2" round handle tang in this system.

What does the laser do?

The laser guides you to precise wall thickness at all times, eliminating the worry of cutting through the wall just as your bowl is complete.

The commercial quality laser is set so the laser light is offset from the cutting tip by the desired wall thickness of the vessel. When you begin hollowing the laser points mostly to the middle of the vessel. As the vessel is hollowed and the cutting tip moves outward the laser light follows. Once the cutter reaches the desired thickness, the laser light falls off the vessel.

What tools work with the SHS?

All full-size Simple Woodturning Tools (see them all here) and any turning tool with a 1/2" round handle tang.
The new longer Simple Scraper IV will work in this Simple Hollowing System with the standard 1/2" tool holder.
Tools with a 3/8" round handle tang (mid-size tools identified by tool engraving starting with M) can be used with the addition of the SHS 1/2” to 3/8” bushing.
Tools with a 5/8" round handle tang can be used by replacing the standard 1/2” tool holder with the optional 5/8" tool holder.

The entire Simple Hollowing System is made by Harrison Specialties in the Land of 10,000 lakes, Minnesota. All components are precision machined on an American made Haas CNC milling machine.

With the laser always showing exactly where the cutter is inside your hollow form or bowl, all the stress and fear of catches is eliminated. Now precise wall thickness is simple to achieve. For example if you what a 1/4" wall thickness simply set the laser light to shine 1/4" away from the cutter. Then hollow out your vessel until the laser light just falls off the outside of the vessel and you will have a 1/4" wall thickness. 

  • This fully articulating hollowing system will fit virtually any lathe with split ways, even mini lathes. 
  • Note: If you own a Nova DVR be sure to let us know and we will ship a mounting base clamp specifically for that lathe. 
  • This system can be used to turn both the inside and outside of a project. That makes it ideal for turners who must turn while seated or who may have other physical limitations making it difficult to hold tools.
  • All Full Size Simple Woodturning Tools®, or the Simple Scraper IV, can be used in the system or any other tool with a half inch round tang.
  • This system will also accept 3/8" (mid size) tools with the addition of the SHS Bushing found here: SHS BUSHING
