Those little flaws will never harm it; Great work as usual!!

DC, in response to 'how often do u use a parting tool/cutoff tool'

More than any operation (maybe cept threading) do I curse my lathe. Mounting it upside down does help on the big lathe, the southbend does not have the correct T-slot top to do that. Anyway, I don’t use it much for 'parting' but it is great for making interrupted cuts, say in the middle of an object where u need to square the shoulders/ring groove etc. I probably use the parting tool almost as much as my typical cutting tool

[SWIGIN]

I agree, I use my parting tool a good bit....or would like to. I hope this makes things easier.

I HATE having to make a part, then sawzall it off then face it. I too use mine to mark shoulders or as a grooving tool.

A member over at practicalmachinists.com held a little get together today for some of the members on that site. I had no idea he was a dealer in lathe parts or I would have gone with a fatter wallet but I made out OK.

I really wanted new jaws for my 5'' 3jaw chuck since it only has the ''backwards'' set. But he could not find any that fit my old chuck so he sold me a nice used 5'' with both sets of jaws and a set of soft jaws. Then I spied a tail stock crotch tool so he sold me that and the 5'' chuck for $40! I have seen the crotch tool go for that or more on ebay. Then after a few laps around his place I spotted a new looking 4 jaw chuck. Mine is shot and the jaws are very sloppy on the chuck body and it's almost unusable. I ask about it, he looks it over and says he'll take $75....so I jumped on it...lol



Practically new 6'' 4jaw, still had cosmoline (spelling?)on it. USA made Union chuck.


crotch tool....I forget the real name...lol


This is the 3 jaw chuck and the other jaws...1 set has never been used!

[Dirtcrasher]

NICE!! 4 jaws do anything! Great find Wayne, this lathe has blown me away from day 1 till now..... You've really done a fantastic job!!

You've really done some great updates on it also!

I want and need a heavy 10 and need to sell my lathe minus the DC leadscrew drive, it's worth about 700$ just for the vari speed drive. All the old stuff is good, I just need a couple critical gears........... I have the complete set of thread gears with no damage, no teeth replaced either........

[SWIGIN]

Thank you sir

I made 2 chuck keys for my new chucks tonight after work. This was the first time I used a dividing head on a milling machine....HOLY CRAP THEY ARE SLICK!

[SWIGIN]

Since I'm bored and my electric just came back on after 10 hours or so I got some pics of the keys I made.



Since this 5'' 3 jaw chuck has suck a fine scroll it takes forever to move the jaws very far I milled 3 flats on the handle end so I can use my drill to speed things up.

Made a thumb screw the other day for my rear tool post holder. The ajustment wedge seems to like to work it's way back till the tool falls out. This will hold it from backing up and let me adjust it in much better.


1'' head with 3/8'' x 24tpi made 100% only using my 89 year old lathe...lol

As of today, I have the ability to cut metric threads on my lathe! I found a few different gear setups that will give me 3 key metric thread pitches, 1.00, 1.25 and 1.50.

I am more then excited about this and can now easily make swing arm bolts or whatever I need to! I just need to make a keyed bushing for my compound gear so I can slide on my own gears to make my old lathe cut a metric thread.

[SWIGIN]

Today I started making the bushings needed for me to cut metric threads. I made 2 since I had 2 different designs in mind but I think I'm going with the one with the smaller hole in it. I just need to cut a 3/16'' wide key way into it and I'm ready to start cutting threads.


I finally threw some paint on that rear tool post I made, and I made a new decal for it. The blue really looks bad in the pic but it's the same blue as everything else.



In this pic you can see that knurled thumb screw I made earlier sticking out of the back of the tool post.

[SWIGIN]

Today I finished my metric threading setup. Every thing works as it should and this will greatly open up what I can make for ATVs.

I had HRE weld me up a T nut while I was there milling my key way, this gets lightly snugged to the bushing. then the whole works gets bolted onto the lathe.

Everything laid out.


Everything installed.

Here are the first metric threads my 89 year old lathe has ever cut. This was a scrap piece of 15mm round stock left over from making front axles for a member on this site. These lathe cut threads look MUCH better then the die cut threads I was doing for him. The nut spins right on like it would on a factory bolt...maybe better!



I guess it is time for me to throw my hat into the ring and offer up my services to guys needing swingarm bolts and front axles.

So if anyone wants or needs things like swingarm bolts or front axles made just send me a PM.

cool , I got ideas,lol

I whipped up a flood coolant system this weekend. I used a $9 fountain/aquarium pump that has 5 flow speeds. This made it nice to dial in the flow I wanted. the pump is powered through a foot pedal switch which I like since I get to have my hands free.





This is an aluminum cap I mad to keep chips and bugs out of my coolant.


This bracket was once on my quad racer back in the 90s. It was a rear brake caliper strut/bracket.


So far I really like it and it works well.

[SWIGIN]

Since I added the coolant system I found out I needed a splash guard. I made this at work today out of 1/8'' plexi and sandwiched it between 2 pieces of aluminum angle. Both angle pieces have a hole in them so I can move it front or back in each T slot.



I might not be done with it, I wont know till I get to turn something but I might lower it.


Here is the main reason for the coolant system and splash guard.



Thats a 4'' low carbon tube with 1/4'' wall. I need to turn 7 of these down to roughly 1/8'' wall for a job at work. So I get to play machinist on the clock...lol

The right end of that tube has an aluminum bushing in it that I made so my bull nose would work.

This pic shows the aluminum bushing I made so my bull nose live center would work.
