Graziano SAG 12 Restoration

[jeffrey jekran]

Hi all,
I Just started a fully restoration on the Graziano sag12
This was the first lathe that i been learning from school so it will be a bit nostalgic for me and about a year ago i been very lucky to find one from an university that has been very little use as of now we strip the machine and when we inspect all of it i can say that it is almost perfect no wear at all the only things that have been wear out are rubber parts and wires that feed the gearbox in the meantime i designed a new splash back to have also the safety door included and DRO

This is the Cad design of the splash back

And this is the build

By the way we also have a Graziano SAG 22 But it is already restored about 4years ago

Hey Jeffrey,
Nice backsplash. That’s going to be a great lathe. Keep posting!

Looking at your photos and trying to understaand that shield along the front way.
I now see that there is a third
Way under there that I suppose helps support the weight of the apron and the extra pressure cutting tools put on the front of the carriage.

I always thought better supporting of some of the extra weight of the apron and tool pressure put on the front Way would help from wearing the backside of the front Way.
Adjusting that would be critical balance.
It may even help reduce wear on the feed rod and leadscrew and their apron drive parts.

Often apron Carriage and Way wear is accelerated by the Carriage hold down adjustments being loose.
Lack of keeping things adjusted.

Jeffery
Thats a nice looking and well-built lathe. I like lathes witth the gearbox driven down on the motor and the spindle being belt driven.
I'm enjoying watching your restoration.
Your gears condition looks great.

Mike,
Here are some photos showing the covered ways. Note also how the raised tailstock ways stop short near the spindle, creating a built-in "gap".
There are several other lathes which use a similar design of raised tailstock ways, covered main ways.

Thanks Peter
I see now tthat the lower ways are the Carriage Ways. The Ways also look nice and wide.
The covers are a nice feature. There still appears to be enough room in between to wipe the ways off although almost all thhe chips will be deflected.

Stopping the tailstock Ways where they aren't needed and lowering the Carriage Ways gives a lot more swing room for the chuck jaws. Nice

These were very expencive lathes at the time
More expensive as a Weiler for example
BTW Do you make the electrical all new ??
Did you figure out the wire diagram that comes with the machine?
I am under the impression the voltage on the clutches drops after innitianal engaging (Not sure as I still cannot find out that wire diagram)
It does not have the break option it seems
I think that can be done with the excisting clutches Not sure though

Hi Guys
Bad news when we apply the primer did not match the Graziano some how so we had to remove all the original paint and start from scratch

 

[jeffrey jekran]

Hi all,
After long hard work finally we are assembling again

 

[macchi7]

Looks like you've done a nice job.

OK, Jeffrey, you win. I was going to fix up my lathe, but I think I’d rather have you do it ;-)
Nice work!

Almost done
