New Build, Aluminium Frame Router/Mill

Better over than under ;)

Day off today so hit the project...

X / Z axis finshed...


Rear face of the tool mount plate with the linear rails...


Front of the Z axis with some linear rail carriages in place...


Back of the Z axis with the X axis carriages in place...


Rear frame support plate fitted to the main beams...


Next up is the front frame plate and mount for the Y axis motor. :)

Bit more today...

The bare frame - extremely rigid, surprised me!


Inside of the front plate (maybe the back, not sure yet) idler bearings to shift the belt path...


The Y axis screws temporarily fitted...


The gantry being built up...


The Z axis in place...


Z axis lifter screw and motor fitted...


So far, my CAD efforts have been 100% perfect, every single part drawn has fitted just where it should be Torsionally, the gantry is very stiff - pushing on one side brings an immediate response from the other which is good, the Z axis looks like it will be just as tight.

Now i need to fabricate an idea for a method of joining the Y axis nuts to the gantry cross-beam.

Tuff littel Bird ain't she.. .

Certainly is Jazz, this thing is probably more rigid then 'Mr Flexy' the Bridgeport ;)

Small progress today, mostly tidying up loose ends and fitting parts...

Looking a nice little build, still lots of fun stuff to do yet!

Is that a belt sander in the background? Warco!!

Is that a belt sander in the background? Warco!!

Yes it is, 4" belt vert/horiz, it's one of the most used tools and one of the most gutless i'm afraid, I really need to build or buy a decent unit with a Hp or two behind it. You have to take your time on it - press on a bit and it just stalls out.

Cheap though and has done a lot of work.

Slight boo-boo uncovered tonight, the belts arrived and the teeth were bigger than i allowed for in my serpentine arrangement, this caused the opposing sides of the belt to rub against each other at the idlers...



First option for fixing it was to order up some smaller diameter bearings, should work ok.
