Longitudinal and Cross Power Feeds for G0602 Type Lathe / Job completed

Hi guys,

I finally completed this job. Planned to do it by the end of May,
but thanks to COVID19, I stayed 2 months longer on board and
arrived home one month ago.

As you can see from the video, it works. And it works flawlessly.

I believe that all details except automatic threading stop can
be seen and understood from the video clip.

Automatic stop for longitudinal feed works perfect when turning to a shoulder.
Repeatability / accuracy 0.05mm (0.002").

Automatic stop for threading will be described in another post / video.

Cheers
LMMasterMariner

thats awesome work!!! thats about the size lathe I wanted but couldent afford, so my wimpy 9x20 will have to do. you now have my mind trying to get in gear....Im not sure I can do this kind of thinking and work any more....those days may be past. I still havent made a feed reverser yet...

Masterful work indeed look forward to your next video.

UPDATE
======

I originally planned to install tumbler for connecting gears on lead screw and feed shaft. These 2 gears were supposed to be 18 and 22 teeth gears. But never made it and found that it wasn't necessary at all. That's why I used 20 and 22 teeth gears without tumbler. Today I found another gears; 18 and 24 and installed them.
Also prepared new Thread and Feed Chart, which still needs to be printed and laminated. But anyhow this chart will be posted once I complete my next project: Additional Screw Cutting Gearbox (Norton type).

Few pictures attached.

Cheers

Im now looking to either make a R8 collet block so i can use R8 collets in my lathe or....I was thinking about the 5c collet that axcepts er32. witch should work fine for the r8 collets/r8 tool holders that I need/ may need too put in my lathe. I have 5c&r8&er32,er11&er16 already along with all kinds of stuff. but it sure would be nice to be able to put my r8 tooling in my lathe sometimes.especialy if I need to make some "adjustments" to it. I may need to install a bushing Z& size to the end of the r8 collet for end support..but the er stuff dont have it, so...Im still thinking. $35 for a hard pressission c5~ER32 COLLET SURE IS A LOT EASIER THAN MAKING ONE.!! i DO REALIZE i WILL HAVE TO WORK ON THE NUT AND GET RID OF THE"CAMLOCK" THEY HAVE TO RETAIN THE ER COLLET AND POSSIABLY ILL ADD A HARDENED WASHER IN THERE TOO.ILL WAITE TILL I DECIDE JUST WHAT I WILL DO TO SEE IF I NEED THAT WASHER. ANY IDEAS OR THOUGHTS ON THIS?

I almost bought ER40-125 (95) Collet Chuck. That one would fit my back plate. It was quite cheap in China, but heavy and I already had more than enough steel in my suitcases. In the meantime I installed motorcycle brake at my chuck, actually to back plate and then it wasn't an option at all. Here are couple of pictures of this collect chuck. But if I have to install it, I will only buy ER40 - A clamping nut and ER40 collets. Would fabricate collet holder in situ, so TIR (total indicated run out) would be almost zero.

Cheers

I was thinking about er40, but I already have all the other stuff and trying to wind down on this stuff,I almost bought er40 last year.my brother has a lot of it, I may go over there to have at weather the R8 will fall through the re 40 or not and go from there. that er40 chuck plate is cheep on ebay now.

Excuse this short OT detour:
Guess LMMasterMariner lives some 155 mi from Pristina - but some 265 miles and 7 hrs by road...

https://en.wikipedia.org/wiki/COVID-...mic_in_Kosovo:
from where one can find:
"On 6 August, sixteen new death cases with coronavirus were confirmed, bringing the total to 300. 196 new positive cases were confirmed, bringing the total to 9,688. 134 recoveries were confirmed, bringing the total to 5,480."

Given these figures and the 1.81 M population, that equals 5353 confirmed cases/ million, and 165 deaths/million.
(Kosovo thus equals Wyoming when it comes to confirmed cases [9th lowest case state in the US],
and compares to Kentucky or Wisconsin [16th & 15th state from the bottom] in mortality as of Aug 6th.)
So depending where in the US your daughter has been living 'til now - she might (statistically) even be better off over there?

I'd say that's pretty low compared to what we have here in Sweden [#23 among all nations, comparable to Washington]
with 8111 confirmed cases/ million, and 570 deaths/ million [#8 in the World, equalling Pennsylvania] as of today...

But then, tomorrow's another day just about anywhere...
