    Default A Router Table Using Linear Rails For a Lift

    My other thread has not had anything added to it because I have been helping Stuart from Illawarra Wood Working School build a new router table. It uses a CNC spindle and two linear rails for the lift using a lead screw operated from the top of the table to change the height. The top is two sheets of 12mm phenolic board because it came from another table. One sheet would have done because there is nothing hanging from underneath the table but the top was already built. A VFD controls the spindle operation and a DRO measures the height neither of which have been finally installed. We will get a 3D printed mount for the DRO head and the VFD panel with the VFD itself remotely mounted. It could have been a lot more complicated but simple in a multi user environment is much better because some people will push any button they see to find out what happens.



    The first picture shows the lead screw and rails installed with the RT laying horizontally on the floor. The height adjuster goes into the silver coupling sitting on top of the black bearing block. It will be a hex drive from an allen key or long screw driver drive and will go through the top. It will be locked via a screw which will be in a steel sleeve and by engaging with the flats it will only require finger pressure to engage it. If we had used a round shaft a lot of locking force would have been needed.

    How much did this cost? The spindle kit with VFD included cost $496 and the rails and screw drive cost just on a $100. I snagged the spindle kit at a great price because normally they are around $550. The DRO cost $35 so all up we have a RT with above the table lift control, digital measurement a CNC spindle for about $650 which kills buying a router and lift by hundreds of dollars. The VFD gives way better speed control with a lot less motor noise. The spindle kit came with a full set of ER20 collets which will allow any size shaft cutter such as end mills etc to be used and I think it will go slow enough to be used as a spindle sander but the jury is still out on that one at the moment. The top can be a single sheet of whatever you choose as it will not have to support 10 kilos of lift and router weight and can be installed to lift off if needed. This means special purpose tops could be utilised for special jobs like pin starts etc.

    Great idea. Would you be able to post a parts list and sources? I know Google Is My Friend, but it would save a lot of time...

    All the parts came from Ebay.....

    DRO: https://www.ebay.com.au/itm/150-200-...72.m2749.l2649


    Spindle Kit: https://www.ebay.com.au/itm/CNC-2-2K...72.m2749.l2649


    Linear Bearing Rails: https://www.ebay.com.au/itm/AU-2PCS-...72.m2749.l2649


    Lead Screw: https://www.ebay.com.au/itm/SFU1204-...72.m2749.l2649

    We used MDF because it is cheap and stable and can also be replaced quickly if damaged. A lot of stuff can flow from this, one thought I had during the build was put the slide assembly on bearings so it can be tilted towards or away from the fence to give the same cutter different results, this has been done by others but using expensive lifts. The idea of different tops is an area I have never seen explored as well. I never understood the noise difference between a router motor and a spindle until I saw this video. keep in mind that it is the cutter that makes a lot of noise on top of the motor. It also shows information about hooking up the VFD to the spindle.
