Wtf CM you got yourself a Milling Machine, you're above amazing and perhaps a bit insane.
Buckling up for the next phase.

CM: "Hey hon, gonna run out and pick up something for the garage ... back in a bit..."

~ four hours later comes home with a mill the size of a Transformer ...

We bow down.

Well - as you can imagine - my wife is....
Ecstatic...

A few mill facts for you:
- Bridgeport's are the Vespa's of the milling world - and of course there are clones.
- The Chinese ones are good - but the Taiwanese ones are the real deal - and some of them have some unique features.
- The heavier a machine is - the less it can chatter. Weight is desirable.
- The best castings from Asia are done in Taiwan using a process called Meehanite. All those castings have a letter "M" molded in on the base.

Mine is a Webb - and it is Taiwanese.
It has Meehanite castings.
It weighs 4000 lbs
...but the table is kinda the perfect garage size of 42"
If you look from the front - half the size of the machine is the electronics.

My plan is:
1. Rip off the David Hasselhof 1980's electronic boxes. These are what failed about a decade ago that caused it to get moth balled.
2. Make some handles for it and get it working as a manual machine (now cleaned and polished, all the mechanisms operate crazy smooth).
3. Upgrade it to a CNC using the existing DC brushed servo motors - combined with modern electronics. These will allow me to keep using it manually too.

Now - I just have to figure out how to get it off the trailer without becoming a YouTube Darwin Award winner.

Off to the garage.


All that stuff on the right that looks like a second machine is going to come off.

pretty fancy!


I wanted a better look at it, you lucky dog! How about a few close up shots for us machinery geeks?

Does it kick over, can you get spark? Looks like somebody will be shopping for some tooling soon...


I have a smaller model...

Voodoo - she is a Webb 5BVK - the big sister to yours.
It was Webb's most powerful machine - but had a reasonable size table.

I was looking for something smaller of course - but as I researched it - I kinda fell in love.
She is stout. 4200 lbs. But all curves - and as I noted - the 1980s electrics double her size.
Table actual dimensions are 42x9 - which seams perfect to me.
5HP 3 phase motor - the Bridgeport I was looking at had a 1HP.
Cant imagine having extra HP will be a bad thing...

All the servos spin nicely - as does the motor. Haven't put them under power yet to see tho.
Owner told me - it "lost its parameters" which the mill cognoscenti tell me is like loosing your mind - but that it was fully functional when that happened - so I am hopeful.

Servos are DC - German ones.
No handles of any kind - as it was all automated - but under the covers are gear drives and it looks pretty easy to add some nice handles for the axis.
I imagine I can MILL the covers to have some nice fit up.

My first move is to rip off the old electronics.
They are huge and dated.
I will add a DRO (digital read out) and readers.
The DC motors will not cause resistance to me turning by hand - so I will keep them.
Phase II will be to make it CNC with modern (smaller) controls.
I've been using my power drill with an 18MM socket to move the drives around.
They just zip up and down and left right.

Safis - hahaha. True.

Swiss - it was a bear. Everyone told me to get help - but I just didnt feel right asking someone to give an entire Memorial Day up - and I was worried about their safety. So - I went it alone. What a day.

Few pics below - and a tiny video for a laugh of the actual moment I got it to roll off (after hours of struggles and hang ups of various kinds).

https://youtu.be/qt2lLSe-_38


Table all cleaned and pretty


Leveled - note the meehanite casting M (gave that a little polish while I was at it). 🙂


Tucked away. I have too much crap in my garage again... So I will have to get rid of some more stuff. Don't think I will need my little drill press any more.

That or Fussion 360 - though I'm not really sure yet.
The machine was abandon when the computer "lost its parameters".
Still trying to figure out what that even means - and if I can help find them.
🙂

But yes - very psyched to have gotten this beast.
Think she would look good in an early 60's Vespa green with polished chrome and aluminum components.
Guys on the machining forum can't understand why I keep talking about what color I want to paint it.

"Son - this is a precision machine! The color is inconsequential!"
Me: "Yeah- ik, ik, but what would I need to do to paint it Verde 399 or 394?"

Don't quote me on this, but there's a long-term battery in CNC machine controllers that keeps track of where it is, what its limits are, etc. Lasts a long time, even when the machine is left unused.
When it dies it doesn't know where it is. Lost its parameters.

Yup - I think that's the battery that died.
Now it needs new controls as best I can tell.'
Hey - it was free!
(not counting the many, many hours of hard labor to make the frame and move it).

I am missing he unicorn something fierce.
Need to sort out a plan that puts it back on the road.

Hahaha. Indeed.
(On phone so pics will go up one at a time)

Preamble:
Jack's rules on cylinder studs:
- what ever u do. Don't remove them
- see previous rule.
- if u do remove them, and they strip, use helicoil
- if the helicoil wears out, use time-cert
- when the time sett fails - u need reconstructive surgery.


So I fit my malossi cylinder on to see how things lined up.
I have a 5mm lift to offset my longer rod.
At issue: the stud that fits the time-cert is a conversion stud. 8mm one end. 7mm shank.
Unfortunately - it's way to short - and no one makes an extended one.
So I took a deep breath - and did what I had to do.

It was like a double mastectomy, with angioplasty rebuild.
All the bad is gone and all the good has been put back.
Supple, pert but with some weight behind it.
Final sculpting still to come.

The. Of course - it will need to be bored.
Some of my finer work.
The patient is resting and happy.

Ray,
Any half wit Australian can buy a bunch of go fast parts and lump them together.
Two birds, one stone.
(Oh, I am gonna pay for that).

As I am passing you - at some rally - in a corner - with a sidecar hanging off the side - with my rejuvenated bodge cases - breathing through their oversized airways - snorting away, I will think of your friend, and shift into 3rd.
🙂

It's a labor of love.

Dr Frankenstein never did anything this scary. There are so many what if's, the chances of overtaking anything on these casings is slim. But if anyone can, I'm sure you can.
To make that weld hard enough to hold a thread, does it need to be heat treated or something? Getting the stud straight will be the pivotal part of the plot. Best hide behind the sofa until then.

Lol. This is all sheer entertainment.

It reminds me of words of wisdom from a smart man...
If you ain't first, you're last.

Well done CM , there was a guy in our town that was an amazing welder and good friend. I called him one night and said I got an emergency, met me at his shop in his slippers and bathrobe, I had a stripped out exhaust stud hole, he automatically ground out the area, welded it back over full , ground the base flat , centre punched and drilled and tapped for a new stud. What you just did brought back a great memory, he's passed now, was a Hells Angel and got himself shot.

I've used timeserts for old non Vespa casings and it's the same idea for lining up. I would make up a plate with all four holes and bam got your jig , well a bit more work than that but I know you can pull it off.

Golly. CM2's let the welding fumes go to his head.

Hmm, how to react. Normally when solving a puzzle on MV I try to "show my workings" with pictures, but any picture taken inside my head would surely not be suitable for a PG rated site like this. So, here instead is a quick run through some possible retorts:

1. (Deflection) It's not fair to pick on Ginch like that. Anyway, I don't think he's actually building an engine at the moment... Rejected Due to Ginch's current "in the love bubble" status it would be unfair to darg him into this.

2. (Subtle insult) No worries Training Wheels Rejected: Due to likelihood of insult sailing over hack rider's head..

3. (Less subtle Insult) Hows that Allstate going. Ready to ride a 2 wheeler yet? Corners can be tricky. Perhaps one of these first?


Rejected: Due (again) to complexity of understanding required.

4. (Immaturity) Asshole Rejected: Saved for future use.

5. (Acquiescence) Awwww! Rejected: 'cos Hell No!

So I'll go with #6. See below.

Meanwhile, couple things about the cases.

If you TIG'd them, the welds shouldn't be a problem to mill, and should be about the same hardness as the original casting. The challenge will be porosity and possible voids in the welds, but you can cross that bridge later. Welding cast sucks - the impurities bubble out and cause all sorts of trouble. If you're planning to mill it, I'd suggest doing what I did for Ginch's smallie motor and weld up a jig to bolt it into. Much easier than trying to clamp it down otherwise.



Also, when you're putting that much heat into the cases, it's worth putting an old bearing in beforehand. I warped one and learnt that the hard way.

Anyway...

6. (Candour) The real challenge for the half wit Australian isn't so much lumping the cases together. It's doing slowly it enough, and with enough simple pictures, that a full strength Californian will be able to understand and follow along when he eventually comes to his senses. Approved

Over to you Training Wheels

Good chuckles to wake up to.
Had to brew a coffee before I opened - and braced.
Yes - that was totally uncalled for.
Craig's response was only restrained, 'cause he knows I'm just jealous.
(though I did appreciate the subtle backhand re-aiming at Ginch he crossed through).
🙂
I will be over at Boss Hogg salivating as soon as I am done typing here.

As penance - I am posting my secrets below.
- Im using 5356. It is stronger than the 4000 series aluminums. Both tough and good tensile. Should be better than parent material.
- I grind everything back first. This gives me fresher metal to work with.
- The first pass is the toughest - I use a lot of "cleaning action" - about 45%
- I "wash" over the surface with my welder - this raises impurities to the surface
- Then I start adding a layer of new aluminum on as I "wash" - this layer of fresh aluminum floats the impurities to its surface.
- Then - I grind that surface with the impurities off - leaving a fresh new metal as my base.
And here is the fancy part that changes the game. (Italian guy does this who I follow)
- I use a ball peen hammer and peen the crap out of the weld. Yup. It compacts the aluminum and makes it super dense - nicer to machine - removing any air bubbles.
- After that - every few passes - I peen it again to keep it super compacted.
I am always stunned by how much the metal moves when I peen it.

This section should be stronger than the casting - and have less impurities and bubbles. If I can bore a straight hole - it should be better than new.

Craig's head's up on the bearing - DOH! - I forgot to do that!!!
Will put a bearing in for the next welds.
I'll also shoot a pic of the peening.

. Gracious.


This is what it looked like after I cut off the time-cert


Same after grinding - it is nerve racking - but often it is better to build up new rather than try to weld on a broken part - so you just have to grind back


This was a mid point. I meant to shoot the picture after I peened. I'll add that to my next post - but this is where it's done

Are these even Vespa cases anymore? Ha! By the time you're done with them, you'll have your own custom molds and be doing castings of vespa engine cases!

As long as he provides the cnc plots open source, I'm cool with that!


What's the going rate of big aluminum blocks big enough to cnc case halves out of?
