Right after spending a few months filing and making all sort of tools that will be used during the second year I was introduced to bench turning with the 8 mm lathe.
I started turning first brass and then in steel with a 45° tips cone carefully checked by my instructor and and practicing with the...
The Pivto Gauges was the next chapter after the Winding Stem sobject as more exercize for learning how to turn blue steel and improving our skills.
During this perod of time we improved our precision skills as the tollerances went smaller ( from hundreds of mm to microns) also in this part of the...
The Hour Wheel was another piece of the winding and setting mechanism that I had to remake as this original component was too quite worn out.
So here once more sitting in front of the lathe and making another wheel.
This wheel hasn't been very difficult to make, unfortunately I lost all the...
Continuing with my restoration project I moved on to the balance staff, when I checked the balance staff in the movement I found out that both pivots were bent, I tried to straighten them but I broke one.
I knew that the only solution was to make a brand new one from scratches rather then search...
The Sliding Pinion has been a real challange to make and the most difficult and important component I made for my school watch.
The major problem I faced was to make the square hole in such a long piece through brass first during prototipe making and then after through steel, for the ratchet and...
After I made the Winding Stem I went on to make a Winding Pinion prototipe in brass, I took all the mesurements from the old worn out winding pinion, planned a strategy of action and then I set up all the gear, lathe (shaublin 70) microscope, milling attachment and cutter.
Chucked a big piece of...
As my instructor and I were quite happy about the result of the prototipe we thought it was time to make the real thing in steel.
So I set up everything once again, sharpened the gravers, chucked a steel rod in the shaublin 70 and off I went to make it.
Followed exactly the same procedures for the...
Restoration is an endless work, one of the original dial screws was broken and both were pretty in a bad condition so I decided once again to remake both of them after as usual discussing it with my instructor, at least there would be both equal and rather then have one new and one old, also more...
Another job that had to be done was the polishing of all the movement screws as they all were in a pretty bad condition, full of burrs and a some were a bit rusty so I decided to refresh them and flat polish all of them.
I took my tripod a steel plate and some diamond paste and off I started...
When I was making the sliding pinion in the beginning I didn't have the right cutter with the right module and I tried different methods but none had worked.
I made a flying cutter in the end I obtained results with the prototipe in brass but when I used it on steel didn't work and I never...
The Click screw is a continuing chapter of the flat polishing, I realized that the thread on the mainplate for the click screw were very worn out and discussing with my instructor we decided that rather then making a new bushing it was better to rethread it and make a new screw as the...
For the making of the prototipe cannon pinion I started by making the cutter post that the school kindly bought for me, I chucked a brass rod and I turned it down, made the shoulder to accomodate the blade, threaded it, bavelled the back, placed a washer, tightened with a bolt and secured with...
During the making of the sliding pinion I made so many punches that I lost count, I think if I rememeber right I made around 10 overall all different sizes, lenght and different tempering
Below a sequence of pictures while I am making one
