as it is not easy to find in the market plunge holders for 43mm euro neck routers, i decided to build my own. it is designed for using with routers up to 80mm diameter for bigger routers, you will need to modify the plans as always i started cutting all the parts using the cutting list
woodworking router hand, next, glue two blocks of plywood to get depth enough to build the neck. stick the template and make the 43mm drill using an adjustable drill bit. as we are using a wide drill bit, we must slow down the speed and due to we are cutting hard material, we'll try to don't press so hard to keep it cold
it must fit kind of tight to avoid the router from loosening i am gonna use here threaded insert so we can adjust the height of milling ...and another one here for holding the router. mechanize now the height adjustment system. i have to make a long drill to build the parallel guide, and as i don't have a drill bit long enough, i have welded a steel rod to one of my drill bits. once we have all the parts ready, we can start assembly. as we are using reduce size pieces, we'll better go with 3mm screws.
insert the screws to mark their final positions and remove them before applying the glue. this way we will avoid the parts from moving. sand this part until it we can easily slide it in its place effortlessly. let's continue with the assembly. mechanized the base and put in place now i'm going to make the knobs glue both parts together and make a drill for the threaded insert. apply the varnish to get a better finish and durability. next i am gonna make the base using acrylic to improve the sliding and transparency.
but this is not strictly necessary. put it in place using a few small screws. insert the router with an 8mm steel rod to use as central axis of rotation to give the base a perfect circular shape. now the milling depth adjustment system and finally let's try it!
