Hi,
V5
Here is the item I wish to make and have machined so as to fit into the threaded holes that exist for it.
Jeremy has shown here
link is:-
that the thread doesnt need to move inwards within one rotation of itself as the cone end takes care of the thread appearing, this ties in with comment on the lathe just makes a constant diameter thread.
Note the tapered end and that this appears to fizzle out on the slope.
lower pic is a quarter turn more CW as I held it to the upper pic.
Images mobile phone SE2020 so not as nice as my Canon 60mm macro !
thread is OD 1.055 inch, shaft is 0.981 inch dia pitch 20 tpi
I dont see any charts with this diameter, as this is a thread made into an item the charts never were aware of and is not a standard item but somewhat specialist. Its BSC cycle thread it seems, made by the same company that did cycles.
A video on using a chart and making a bolt as on the chart would be meaningful to folk.
Following Jeremys cone end. Here the cone isnt 45deg but if 45 deg is a known angle then follow 45 deg.
