Hi Deckeleers,
This purchase of an FP2 high speed head may throw some light on some of the details of Kevin`s high speed head.
The part number stamped on the body casting is 2020/1907. Here i`m presuming that 2020 is the model No. and 1907 the sequence number of the head which means that as Kevin`s head is numbered 2066, so my head is 159 earlier.
The spindle taper is N40 and has the slots for holding the spindle.
In this photo you can see that this head has the top cover missing and that there are ball bearings within.
This head is not for sale and if I can`t find a spare top cover then I will have to make one but am not sure what material is required to make it. This material could be Aluminium or steel, i`ve looked at the cross section drawings in the spare parts manuals but these do not state what materials the parts are made from!
There is an interesting story behind this Ebay UK purchase made several years ago. I tried to research the purchase details on my ebay purchase history but this only goes back to 2016 so the purchase was probably made in 2015.
If my memory is correct, he seller listed an FP2 dividing head which was missing some small parts but came with the overarm and Imperial arbors, which I won for £300. Then he listed the casting of the body of the high speed head separately from the head itself and then after a few days the head. I bid on the body which I thought could be used to mount a Bridgeport "M" type head on by making a suitable adapter. Then I bid on the head itself and won it for £320.
As I had bought two items the seller then threw in the body casting for free.
The Casing, motor and pulley were missing but Eric from Denmark was able to organize the sale of these items to me from a friend of his that had converted his high speed head to electronic control and did not need them.
The motor is the standard dual voltage Siemens item as Kevin`s and this has a keyed shaft but the pulley, which is used and looks correct, does not have a keyway in the bore! I`m not complaining about this, just curious. Perhaps it`s from an FP1 High speed head. The paint on the motor and cover matches the body and head.
The seller, a very nice gentleman told me when I went to pick up the items in Wolverhampton, that these parts were all that remained from two FP2`s that had been scrapped by the company that he works for. On inspection I can see that these items have had very little use and have just been badly stored for many years.
