Updates Available to Opus1 Owners

interested in any of the following Updates:
The CANTILEVER CENTER WHEEL design has now been paired with a new CLIP-LESS BED. The clips are now replaced with two grippers and hold the cane securely in the bed. Since the cane is help in this fashion, there is no more migration of the cane in the bed while it is being gouged. With clips, the position of the cane in the bed is a balance of the PULLING of the BLADE and the PUSHING of the GUIDE. If these forces balance, the cane does not move. If the forces are not balanced, the is a net force on the cane that causes it to move slightly in the bed either towards you or towards the main rod of the machine. If the blade is misaligned, this same effect cane be present. With the cane being "gripped" in the bed, this movement is totally eliminated. This guarantees that a particular point on the blade is always going over the same point in the cane. It helps to produce symmetry in the curve.
The current Blade and Guide combination is 1436. This combination is a result of scaling the contours to compensate for errors in the Starrett Radius Gauges used for the initial dimensions. These gauges are STAMPED and not machined to their final shape. They are fairly accurate but, most importantly, very consistent between different gauges. Since the guides and blades are digitized to specifications resulting from measurements with this type of gauge, it became necessary to determine the scale factor that corrected for the slight error inherent in them. It turns out that the gauges measure slightly undersized. A "true" 12mm guide would measure to be slightly bigger than 12mm on a Starrett Radius Gauge. 1436 takes into account the scaling needed to correct this problem. There is also a feathering of the contour with this guide.
The 1420 contour is still available and many people have found it to work well for them.
There have been continuous modifications to the production techniques used to make the carriage of the Opus1 gouger. The carriage has now been modified to allow the carriage to be disassembled WITHOUT removing the blade. This is the first step in having multiple guides available for one machine. Since the blade and guide work as a team, it only makes sense to have the blade, and its alignment with the guide, fixed with the guide.
There is a new Guide Contour available now. The "M2 Contour" is a continuation of the incorporation of "Hand Modifications" into the toolpaths used to cut the guide contour. There are areas in the ribs of the guide that are "Lapped" into shape with files and sand paper. These areas are determined by rub marks on the guide from the cane being cut. These locations are analyzed and their geometry is used to modify the computer model of the guide. New surfaces are created and toolpaths regenerated. This is an ongoing process, but this current version looks and feels very good. If your machine has a serial number less than 20, contact me and we can arrange to have this modification performed on your machine.
A digital copy of a blade made by John Mack has been digitized and transformed into tool paths that are now ground onto the Opus1 blade. The current blade contour is MO.
The guide is now a CONTOURED SURFACE that has been created from this blade to give optimum edge exposure. The current guide contour being cut is MO14.
The cane stop pins have been replaced with a cane stop bar. This solves the problem of cane jumping out of the bed if the guillotine does not cut a clean surface on the ends of the cane. There have only been 2 incidences of this occurring, but to prevent any further problems, I have redesigned this component from the ground up.
The clips have been modified so that the part holding the spring is thicker. This prevents any problems of the spring pulling through the material after long use.
