Keep teaching us. Good to learn the tricks.

all right then
single fucking point thread generating in the lathe
i was doing a pair of FOX FACTORY shocks had fabbed up the rods a few weeks ago along with 4 otheres better in numbers ya know
but i had left them unfinished for to cut to lentgh when needed anyway itsa 7/16-20 unf thread RH v60 degree std shit on the end of 1/2 round rod
i copied exactly the fox factory, goddam that types easy ,i copied there exact design ,you will notice a nice little radius relief up at shoulder very impoortant that this be there and nicely rounded so as not to fucus stress
when s-p threading you dont plunge the cuts ,that is not straight in with the cross slide it will hunt wander and chatter like a fucker
do not try to use a carbide theading cutter in your home lathe i wont say it again thjerte lots of reasons why not the main one being is you will never learn to sp thread
i use an old school high speed threading scroll dealy high speed is plenty fine it wont carry the heat lode of coba;lt but it is much easier to hone an edge on
get in the habbit of honing the edges specially in aluminum and esp the chip mpath the top face that the chip is sliding on
more latter notice ;; the crosslide at 0 ,handle at 6 on clocking the 29 degree setting on the compound, at zero, clocking position not a matter

dont worry about it looking ruff ,and on this turn i had extra stock in length so i left it to be cut off later,.bonus it gives you room to breath ,the little stub gets cut of and when threads are finishing the top layer is filed-in anyway

 

[xb33bsa]

so the crosslide always return it to zero before starting next cut
the compound is what you talker cuts with .010" at a pass is fine band 3-4 passes take a pass with just tool pressure
there are several mways tyo measure threads 3 wire method is va good one fior a really precise size
i just go by the fact that if you start out like on this thread right on or a few thou under .4375" diameter well the threads are very near to depth when they come up sharp a few strokes of a smooth file and you get nice looking threads test them with a nut it ie easy to go too far i cheat many times and final size the thread with a die at least a die is good for something that way

Is this a good learner lathe or is the mini grizly better

the atlas is a good little lathe but you want to get a lathe with quick change lead screw gearbox and if i was buying a lathe today i woulkd also get one that will cut metric or imperial threads
dont buy a chinese lathe they have a long ways to go till they reach a higher level of quality ,that or we just join them
if we dont stop obama and his black lives matter, racists now , we will be there sooner than you know

I don't want to buy something for dust to settle on, if I do this i want to learn to make a few basic things and be able to make bot sae and metric threads for sure, then teach the boy so when all this shit goes to him he will be able to make use of it.
