ABSTRACT:
A router lift adjustment mechanism for an inverted router (50, 52) mounted to a router table (92) comprising an assortment of attachments, FIG.9(98a,98b,98c,98d) that engage the height adjustment mechanism of various types of routers. The routers height adjustment mechanism, the attachment's (98a,98b,98c,98d), a flexible attachment holder (100), a driving shaft (104), and a rotatable adjustment mechanism, typically a hand wheel (122) are contiguously coupled respectively. The driving shaft is retained by a rocker drive guide (112) providing the driving shaft (104) the ability to rotate and slide to and fro within the bore of a bushing (114) lined within the rocker drive guide (112). Additionally, the rocker drive guide (112) hinges pivotably on the base mount (128) which is typically mounted to a stable surface. The rotatability, pivotability and slidability of the driving shaft (104) and rocker drive guide (112) assembly prevent any binding of the driving shaft (104) upon movement of the router adjustment mechanism; thus providing a quick, safe and stable method for adjusting the depth of a router bit (90). The present embodiment can be retrofitted to a wide variety of existing routers and adjustment apparatuses that rotate; including those that rotate and move spirally or provided as a feature of a newly manufactured router.
