this SV102 lathe in a very poor condition from Gawler, South Australia
restored it over several years.
It may be the only flat belt Schaublin 102 lathe of this model and age still running in Australia.
Information regarding early 102 models is quite limited and not totally accurate. One point not identified on other sites concerns the provision of a thrust race on the spindle. This appears to be a later addition and the first 102's did not have it.
The headstock spindle of the lathe shown incorporates a large ball bearing thrust race at the rear end. Interestingly, a second mint condition headstock I have does not include or make provision for this race. This suggests it is an even earlier production model and that they first came without this feature. The thrust race was obviously added to overcome the common issue of the front tapered spindle bush binding from end load, during operations such as centre drilling.
It is also worth noting that only the rear plain/parallel spindle bush is bronze, the front tapered bush being steel on steel. This is the case with both first generation 102 headstocks in my possession.
I resprayed it in the original satin black enamel colour as delivered, directly onto the metal casting, as was the practice of the day.
Interestingly, both my early 102 head and tail stocks were originally painted black.
In the photo it's fitted with an ER32 collet mount, and used mainly for this type of work.
It came with the original draw tube and a set of Imperial W20 collets, plus items including a face plate, rest, badly worn English BSA scroll chuck, and an excellent four jaw Pratt Bernurd chuck.
The wire wick oilers were fabricated during restoration to replace grease nipples that had been fitted (LOL). Original oilers are all brass, and of a similar size - seen below from the earlier headstock.
These can't be fitted to the current headstock as the thread has been opened out/altered to a larger size.
The wire wicks are a "J" shaped single steel wire of 0.04" diameter. I used 0.06" diameter initially, but this over oiled the spindle, so I went to a smaller size.
I use SAE 30 car engine oil in the pots. I was using Dexron 3 ATF fluid, but it was too thin and sprayed about making a mess.
Spindle speeds are configured at 405, 665 and 1050 RPM.
The lathe is driven by a half horse power, single phase, dual capacitor start, heavy cast iron framed, squirrel cage, Australian McColl Electric Works induction motor of similar vintage. Type J045 seen below.
This also acts as the counter balance weight for the pivoting drive belt arm and intermediate pulleys.
The face plate is very well used, with lots of mounting holes drilled and tapped into it.
The original W20 collet draw tube has a massive solid copper end on it.
The compound mount dovetails all had to be re-worked to restore accuracy.
The cross slide screw thread is unusual in that it is turned counter clockwise to advance the slide. The reference scale is graduated clockwise. The thread may have been replaced during the lathes history.
The tailstock has the usual camlock. The original 2 degree quill taper has been replaced with a standard Morse No. 1. This was a common modification in later years.
I also have a heavy duty Morse No. 2 tailstock in mint condition, which like the cross slide, turns anti clockwise to extend/advance the quill. Seen below.
You can see from the colour of the drive belts that this lathe is not an ornament. It is regularly used and still earning it's keep 80 years on.
Here's a few videos of the lathe.
A beautiful old lathe that now runs perfectly, and is a pleasure to use.
I trust you enjoyed the photos.
