Re: DRO on a shaper fence?
¿ªÔÆÌåÓýHi David,Yes the micro-adjust is tightened and so are the fence plates. The hood is machined perfectly, allowing no perceptible movement. Thanks to this discussion, I measured the play in the micro-adjust and it is ~0.005¡± (video attached). This multiplies over 26 inches, the way I have the fence plates right now, for a router bit. This will get worse with a larger shaper cutter. This has been my concern over the utility of adding a DRO. Because of this, I always check squareness, using Lamb Tool¡¯s big triangle, if using the xcut fence. Imran Malik IAM Wood Creations On Mar 23, 2025, at 12:01?PM, David P.

?Imran, some amount of sloppy hood registration as shown in your video is normal for that Shaper Fence 230. The alignment plate that registers the fence to the cast iron top has two pins that mate with holes in the top (p 117 is Survival Guide), and that interface is non-precision and has play in it. ?The mounting plate to hood connection is also non-precision. ?Have you checked to ensure the mounting plate to shaper hood attachment is solid and that the micro-adjust is locked and secured with the Kipp lever? ? Adding a DRO to the shaper hood is not going to improve repeatability and eliminate the need to take test cuts unless the sloppiness of the mounting platform is resolved as part of the DRO mechanical structure. ?
