Thank you very much for the pictures and the explanation Andre!
I surelly learned a lot by looking how a real professional tackles the problem.
After seeing the beaver mill in real yesterday I surely didn't wanted to miss anything of the build!
For those who are waiting for more pictures, "The best has yet to come"!
Thanks again for the great coverage of the mill conversion.
Kind regars,
Julien
Hello everyone,
I've been busy lately but here are some more pictures of the build.
First I made some adjustments to the motor support
so I have enough room for the motor for the Z axis.Attachment 2964
After making the assembly for the Z axis painting it was a pleasure.
I've chosen a black paint to get a two-tone effect.
On the picture we can also see the clamp that will be used for clamping the counterweight cable .
Attachment 2965
Now I have some more to assemble.
I builded together the knee.
Attachment 2966Attachment 2967Attachment 2968
Then I thought having not enough height in the Z so I started making a extension piece
that was faster said than done because I had a metal ring that was to smale on the outside and inside .
On te picture you see the ring when finished.
Here are some pictures of work on the extension piece

have fun
Kind regards Andre
To assemble the extension piece on the turret I had to make bolts myself because I could not buy these bolts in a store.
A simple task if there is no hexagon slot in it.

Probably too late now but just spent ages looking for a picture of a Bridgy owned by a guy in Canada ? who had built a horizontal drive into the riser
Hello John,
and did you found the photos you where looking for?
Kind regards,
Andre
No I am still looking.
It was a tiny picture as it came off Craigs list when the machine was up for sale after the owners death.
It looked like a casting as the lower bolts were short ones and sunk into cast pockets at the side.
The head was part of a J head in that it used the spindle and quill and had the varispeed motor arrangement at the rear.
Still looking.
John with the riser you mean the Z axis i supposed ?
Because I did a complete redesign of it on my machine and if you want some more pictures I can provide.
It was a conventional manual bridgy with nod and tilt head but it had a horizontal spindle thru the riser, front to back.
After the bolts were finished we put on the turret.
The next thing I wanted to do was rebuilding the spindle.
But first we had it disassembled.
And some more of the same.
And more pictures
This was part of the dismantling .
Now we going to modify it some and put it back together.
First measure the part and make some notes and later I made some extra holes in it to be used in a later stage for mounting a ring to get cooling on to the workpiece.
We have to make a new motor support because it is having a special flange
First we put the flange on the machine and made holes in it so we can use them later as a center for alignment for milling the arcs of the part.
And start with roughing .
After making sure the workpiece is in the center of the machine I started with
roughing the outer arc.
After that we are roughing the cylindrical section and then turn over the workpiece and cut away the biggest arc.
But first we made the small arc .
After finishing the outer arc the arc shaped slots ware made.
In a later stage the piece is taken in the chuck of my lathe.
The first operations are facing of and drilling .
With a other tool we made the chamber for the motor.
After turning over the workpiece the other side is machined .
Now the workpiece is going back to the milling machine and it is centered and holes ware made in to it so the motor can be attached .
In to the side of the flange a tapped hole is made to attach a handle for tightening the belt of the motor.
now the motor flange is ready for paint.
After painting this is the result.
Here are all the motors and the finished flange
Now the spindle is assembled with new bearings and new paint.
The motor is put on.
And this is the result of all this work.
Okay I hoop you can find something useful in it .
Until the next set of foto's are ready.
Kind regards ,
Andre.
That looks terrific Andre :)
(now you've finished using that old Maho, could you just pop it in jiffy bag and post it to me?:joker: )
Amazing piece of work Andre.:tup:
as a beginner I can only watch on in awe and try and learn something from your build log.
keep up the great work,can't wait to see the finished result....
more videos please:naughty:
:beer: Tom...
I cant wait to see the result myself.
Super work there Andre. What control board are you using from your PC to the servo drives? i see you are using a pokeys for plenty of IO.
They told me it was an standard breakout board but I now not much of electronic and I have a friend who does that for me.
Hello guys (girls),
Here we are again.
It's been a while and in the meanwhile I got for my birthday an upgrade for my OneCNC cam module and got the Expert license now.
So now I can do everything in 3d ,designing and machining.
I'm so full of joy .
Andre.
Experience is the sum of stupidities you have done.
