I have a 1954 model Myford 7 ''table model''
Recently re-aligned the spindle bearings and slides, so it should be good for another 50 years.
Every one can make own treading tap with a lathe as i did, see the pic...
Use drill rod as material, it is strong enough to treading in soft material such as in aluminium, brass..
Do not hardening the homemade treading tap or you will distort the tap for all perfect treading measure.
Gents,
I am an instrumentation engineer.
For my 30 years old second hand ENYA 60 4C I did need new thread for the glow plug.
For that I do make the "helicoil" myself, it's the only and better solution in such a little 4 stroke.
My lathe? for 40 years my little EMCO Unimat "table model"!
This is a time consuming activity only to use for unique engines and without you have the possibility to buy a new "head".
Remember, there is no Glow-plug tap on the world that brings you the metal back that's gone!!
"Dutch modelers do it on the table" (LOL)
