Take The Guesswork out of Height Adjustment
Routing can bring high-level machining accuracy to any woodworking project. Even the slightest unsightly gap can create a lot more hard work fixing the problem, or end up wasting valuable material. The Sherwood Router Lift fixes one axis of adjustment by bringing perfect accuracy to bit height adjustment.
The top mounting plate is identical to the standard aluminium router mounting plates - milled and CNC-machined from 6mm-thick aluminium plate. Over and above the standard mounting plate, a few extra holes are machined to mount the lift assembly underneath. The aluminium is anodized and then checked for flatness after this important step. Where necessary, each plate is checked and adjusted for flatness for a perfect smooth surface closest to the bit - where it matters most.
There are six grub screws installed along the edges of the mount plate to ensure a perfectly level fit on the lip of the router table underneath it. The radius on the corner of the mounting plate is 16mm, so using a standard 5/8in or 16mm straight bit will provide a perfectly match radius in the corner if you are making your own table.
The centre hole is 92.2mm diameter and includes one phenolic twist-lock insert ring that has a 38.1mm aperture. The insert ring spanner comes standard with the mount plate as well as a starter pin and two holes to mount it either to the left or the right of the bit.
Four Pillar Design.
This lift has four pillars at each extremity of the lift - all threaded so that when the cradle is adjusted - they all act in unison to keep the cradle perfectly parallel to the top plate. The threaded rod is dead-straight, heavy-duty hardened black steel that will last a lifetime.
The pitch of the thread has been set so that a full revoluation of the winder handle results in exactly 2.00mm of height adjustment - a quarter turn is exactly 0.5mm and even the positive action of one graduation is as fine as 0.1mm. There is minimal backlash so you have certainty that you can make these fine adjustments and rely on their accuracy.
Each post has sealed long-life bearings along with automotive-grade sprockets and drive chains. Two extra floating sprockets allows for smooth chain adjustment that virtually eliminates the backlash, providing those most accurate of height adjustments.
The cradle is a huge piece of cast aluminium. Vibration is the enemy of routing - it can cause chattering on the work piece and even worse - ruin router bits and router shafts and bearings. Vibration is absorbed through this massive reinforced cradle. All the important parts are machined multiple times so that the mounting system mates perfectly square with the mounting plate above it.
The swiss-cheese mounting plate is held in place with four clamps. Remove the mount plate - find the holes that line up with your plunge routers base plate holes, mount the lift plate to it and place the router back in the lift. The clamps click in place in the lip between the mount plate and the main router base. Tighten the clamps and the plunge router becomes one with the lift.

Please note that many plunge routers available have quite a wide footprint and this can make it difficult to keep them within the overall dimension of the aperture on router tables. For this reason we recommend the Hitach M12VE router where the handles can be removed for the easiest mounting in the router table. All other routers will fit but due to the limitations of the design, you may need to "hook" the router handles into the table before lowering the lift and router completely.
We've Got a Lock.
Built into the table top is a locking mechanism that engages a brake on one of the four posts to prevent any further movement once the height has been set. The positive locking action is guaranteed to prevent any unwanted movement. Once you've got it set, get routing.
The new Sherwood Router Table range has moved to the North American industry-standard size 298 x 235mm, so this lift now has the same size top mounting plate. This lift can also be used in other brands of tables such as Kreg, Incra, JessEm etc.
