Cutting Frames

Here is our listing of accessories made to fit and work with your Rose Engine.

Many of these accessories will also work with other models of rose engines.

Large Eccentric Cutter (ECF)

ER 16 Drilling Frame with ECF

Eccentric Cutter Head (ECF)

Universal Cutting Frame (overhead)


This is a larger version of the ECF of Fred Armbruster's design that we have produced for years.  It can reach to 3" in diameter and employ cutters of 1/8", 3/16", and 1/4". 

It comes standard with a short and long tool holding block in each of these sizes.  The larger tool has the advantage of mass and produces less tool chatter; however, it does not replace the smaller tool for smaller work.  While larger and more stable the tool must be well balanced. This can be quickly obtained with some practice.  The extra tool holders are used to accomplish balance.  It's also not recommended to run this tool at speeds over 1500 RPM's.  It comes standard with an 8MM collet compatible shank but other sizes can be made upon request for a nominal cost.

This drilling frame uses ER 16 collets, five of which are included which will accommodate 1/8", 3/16", ¼", 5/16", and 3/8".  The spindle can be shortened or extended in the bearings by loosening the shaft collars and sliding it to a new position in order to allow for reaching into tighter spots.  The aluminum bearing block mounts into a typical tool quick change tool holder and features non-contact, sealed bearings that deliver a freer running and cooler operation.   Also included is an eccentric cutter of Fred Armbruster's design with a 60 degree carbide cutter (other angles available).  The cutting frame accepts 1/8" diameter cutters.  The set also has one 3/16" fly cutter that is useful as an internal cutting frame and for thread cutting. 

The individual components are also available and priced upon application.

Horizontal Cutting Frame with carbide cutters

Note: Guarding removed for demonstration purposes only.

Eccentric Cutter Head with 3/8" shank - The eccentric cutter head is considered by many to be the most versatile tool in ornamental turning, and this one, which was designed by Fred Armbruster, is a proven design. It is a compact and well balanced tool that can handle recommended speeds up to 6000 RPM's. Its design keeps the cutter head close to the frame body to reduce vibration and give better results. The clamping bolt is offset from the center allowing for circles to be cut from about 1/8" diameter to just over 1 1/8".  The cutter head incorporates a 1/8" round tool bit holder and comes with a 60-degree carbide bit.  As tools are often specially ground by the user of the eccentric cutter the tools are made to be changed quickly and easily with a socket head set screw. The tool block is held in by the clamping screw for safety in such a way that it cannot come away from the cutter head. The major diameter of the cutter head is 1 1/8", and the shanks come in either 3/8", 8MM (WW) collet style, or a 1/2" shank meant to be turned to the desired size for special applications.

This is the tool used to make the famous "fish" as well as the more standard barleycorn pattern. Half squares can easily be made with it as well as the pineapple style decorations so often associated with ornamental turning. One can also create convex shaped rings around the edges of projects. The uses are too numerous to mention, but are fully described in Holtzappfel No. 5, Evans, and Walshaw books.

There are two 1/8" studs in the face of the tool to allow one to measure the diameter being cut by simply placing their calipers across the two studs on one end and the cutter on the other. The offset is easily measured and is repeatable.

Universal Cutting Frame

Note: Guarding removed for demonstration purposes only.

Universal Cutting Frame (UCF) -The Universal Cutting Frame is a versatile tool because it can be used at any angle from vertical to horizontal.  This tool requires the use of an overhead drive which gives smooth and quiet operation. 

It is available with either one of the two above cutting heads; carbide cutters or 3/16" round cutters, please specify when ordering.  The pulleys are made from steel and ride on high grade Japanese shielded bearings. 

The UCF can be driven by belts from 1/8" to 3/16"; the small belt that drives the head is 1/8" and is included. 

The shank is 9/16" square making it usable in older style slide rests.
