1.7*0.74*0.4m Mill / Router building...

looks well tidy to me:) i could live in that workshop

It's much tidier than it was yesterday! There was a layer of swarf on the floor.

I want to get a metal bandsaw, but I'm rapidly running out of space.

What's the diameter of the shank of those 5mm cutters you pointed me to? Also flute length?

What is your real age? far too clean for 18

18 is my real age :lol: What do you mean by far 'too clean'?

im not at home at the mo dude,,, ill let you know... they are long enough for my er11 with the tread clear of the collet

What do you mean by far 'too clean'?

hahaha! your 18... its ment to look like you dropped a box of grenades in there :)

thats some work shop at your disposal lad.

indeed ! im exspecting you and your old man to build a flux capacitor to go in the delorean when your done :)

shank=5mm
the blade is about 10mm with about 5mm clearance above that (15mm cut depth)
theres aprox 20mm of clean shank to grip onto
13mm of coarse (1.3mm pitch) thread 5.7mm diameter

check your er16 5mm collet to see how much shaft you need

shank=5mm
the blade is about 10mm with about 5mm clearance above that (15mm cut depth)....

Thanks for the info. I'll probably buy some.

Action shot, suspicious lack of swarf :confused::

View of gantry:

Z axis, extended to about 390mm:

Whole router, Dad snuck in on this photo (everyone suddenly appears in the workshop when it starts working!):

Christ if i could keep my workshop as clean as yours is dirty i would be heaven................Where do you keep the tesla coil?

[Jonathan]

It works!!!

I'll add photos/vid shortly.

I did a relief thing, 200x200mm ... 1mm stepover with a 6mm cutter. Varied the feedrate and seemed ok at 3000mm/min. One of the X motors stalled, twice, so that needs looking into. The result doesn't look very good, but that's due to using a flat not rounded cutter since I didn't have one.

looking good jonathan (the router that is, you need a hair cut :)
hows it getting on with thet much Z ?
have you made a provision to drop the whole gantry down for your smaller /finer jobs ?
it is a good feeling when the thing springs into life :)

iv was having trouble with one of my X motors stalling, i had to back off on the speed, i swapped channels and the same motor stalled, im thinking there is slightly more drag on that side
i might swap the bearings for double row A/C bearings to make sure the drag is identical

It seems fine. There's a bit of wobble visible on the latest part (see below), but I think other factors are contributing such as the whole router wobbling madly due to the floor not being strong enough...

I have measured the Z deflection parallel to X. I can bend the Z axis by about 0.06mm if I push as hard as I can with little finger, so a reasonable force but not huge. It takes a lot of force to bend it more than that which makes me think it's the linear bearings that are a bit sloppy. Not much I can do about that.

I've not made it so I can lower the gantry, it's far to heavy to be doing that sort of thing. I think I'll make a raised bed and machine aluminium stuff on that. It's a compromise, but the gantry sides are very strong.

Yes one X motor is much stiffer than the other. It's limiting my feedrate...

Anyway, at last here's a video of it running:



(I'll post the first test video tomorrow when I've edited it)
