Glad to see the threading chart pullout in the latest ME workshop. The one on my workshop wall (which came from a long ago MEW) has become yellowed and a bit coolant spattered so is getting rather hard for me to read!
Keep up the good work!
|Thread: What did you do today (2015)|
Today I machined a 1929 Ford model A cylinder head for a mate.
It was bought to me because it was warped, I could easily get an .008" feeler under the centre of the head when it was on my surface plate. But it needed .050" off to clean up the corrosion around the waterways on the head face -these motors must have seen years of no or at best minimal maintenance, so antifreeze not being changed (or even used) is bound to have left its mark.
An unlooked for minor drama whilst machining the head was one of the contactors burning out. I had noticed a slight burning Shellac aroma whilst working earlier and had checked that the spindle motor, coolant pump and table power feed motor weren't overheating. A while later a plume of smoke came out of the mill's electrics box, and this was the item responsible for the burnt Shellac smell.
A quick hunt through my "it'll come in useful one day box" turned up a contactor with a 415V coil which had came out of a old Schaublin lathe. Wrestled it into place on the Bridgeport and finished the cylinder head off rather later in the day than planned.
Still, all's well that ends well eh?

|Thread: Bridgeport Contactor Problem|
Have you checked that the aux contact is making OK when the contactor is operated? Would have thought it has to be either a problem with the aux contact not making or the stop button (which usually just breaks the aux circuit when pressed) being permanently open circuit.

Just got this finished today -it's a complete "spare" 4W toolpost for my S & B lathe -it's a complete unit that will just slide into the visible tee slot in the topslide.
I made the original (on the left in the photos) about 35 years ago just after I bought the lathe -the machine had come with an incomplete single way toolpost. The minimum order of this size of steel from the stockholder's turned out to be big enough to make three toolposts. Of course, once one was made, the other two pieces that I had cut with my donkey saw languished in the "short ends" box. Over the years, one of them has been lost in the couple of house/workshop moves since.
It wasn't any attack of engineering zeal that caused me to finally get round to making a second toolpost (which is now loaded with four different tools to create an alternative quick change tool setup). Two months ago I had an accident at home and had a short stay hospital stay where they kindly added some Titanium into my leg and put a plaster cast round it. I have discovered that being on crutches or in a wheelchair means that machining is still acheivable from a seated position, the only downside is being positioned at exactly the right level to get a facefull of hot swarf or coolant.
Not sure if this is the usage that the NHS had in mind when they issued my new workshop stool!
The plaster cast is off now, so looking forward to spending more "upright" time in the workshop once I get some more movement back in my foot.
