Ok, so far I have sourced the V-Groove bearings and rails, and the Ball Screws!
This design is going to be built around a 24" x24" T-Slot plate. (The biggest I can make in my little shop)
Here are some snapshots of the basic CAD design I have chosen for the base slide assembly.
The T-slot plate will be 1/2" thick MIC-6 with 1/4" T-Slots spaced every 3".
The V-Rails will be supported by the "L" shaped tracks which will be machined from solid 6061 aluminum.
The L-track will also be used as the machines mounting feet.
The base slide will also be 6061, and have 4 V-Groove bearings on each end.
This Router will have mounting holes for NEMA-34 motors too!
The metal materials will be purchased from Speedy Metals in Wisconsin, the V-Tracks and bearings will come from McMaster Carr, and the Ball Screw will come from HOMESHOPCNC
Cost per one MIC-6 plate: $171.80
Cost per one Ball Nut: $95.00
Cost per one Ball Screw: $49.14
Cost per two V-Roller assemblies: $102.98 ea
Cost per two Double-V rails: $45.04 ea
The pre assembled V-Track units will be dismantled from the little rectangular plate, and custom fitted to the ends of the slide block. These units use a Double-V rail & .593" OD bearings, which allows me to make things a little more compact, thus reducing material costs.
I plan on building only one of these as a prototype, and will most likely make many changes along the way! One of the features I likes about the Ball Screw Nut was that it has an OIL hole! So this router will have small tubing and oil passages throughout! The other features is the 4-ball tracks and has rubber seals on the screws to keep oil in and dirt out, plus its preloaded!
This is looking like a fun (and expensive) project! Better mortgage your house ClaudioG
To be continued!
