What lathe?

[LegDeLimber]

I think on the grinder idea, you'd need to be darn careful to not nick the walls
and the variations from hand cutting would make figuring out your cut more complicated.

But I did use to sometimes grab a side grinder and knock off the mill scale on hot rolled steel
to reduce tool dulling and make layout/marking easier.

I had an import wedge type and I hated it. It would take 3/4 of a turn before it felt like it locked down. I picked that Dorian Super toolpost of the bay about a month ago. It was all rusty so no one was bidding on it. Turns out it was just shelf rust and it was brand new, still had the plastic on the nameplate. I got it for $150. I'm yet to use it with my boring bar but I hope it fixes the chattering problem I had.

I bought a 14x40 lathe that was built in Brazil. I paid 500.00 for the lathe,all I had to do to the lathe was cut a few new change gears for it. It came with an Aloris post and about 12 holders and all had carbide tools in the. Darn crack heads stole that set up before I ever got to use it. I had planed on selling the lathe and keeping the post and holders for myself.

My Dorian is the Super. I picked it up used with 10 holders for 550 but it was mint. The holders are Dorian and Aloris with one odd import. The import hold works fine but it had soft screws in it.

Your 1/2 bar should work well in your holder. I use a 5/8 left hand bar for the chambers.

That is a 13x40" older Jet lathe (made in Taiwan, not China). It came with the Bison 6.25" 3 jaw, 4 jaw, 5C collet closer, import wedge toolpost, some import holders, a few import indexable turning tools and two solid carbide indexable kentametal boring bars (3/8", and 1/2") . All for $1400. The lathe had a 5hp 3 phase motor in it but I put a 3hp single phase for my shop power. I don't have the two change gears to cover all metric thread but I can do most metric and all standard.

I've bought a hodge-podge of import holders since and I recently found a import BXA #2 XL holder so it can hold 3/4" tooling. Yes I've found the screws to be the down fall of some of the imports. The good one's have 5mm instead of 4mm hex heads in the set screws.

Now that I've got the collet closer working well I'll probably by an import set of collets and a nice larger boring bar and then I think I'm done on lathe tooling for a while. I got my eye on a 2 axis CNC mill I just have to borrow a trailer and get there. What is your opinion of the Universal Kwik-Switch 200 tooling beside darn expensive since there is no import? It's on a 5hp Tree mill, big American iron.

You and I both need DRO for our lathes. LOL

I have a Clausing Kondia mill with DRO that had the Kwik-Switch spindle in it and some tooling. It also came with the R8 spindle. I used it for a while that way then later on I installed the R8 in it. If I made my living running the mill every day I would use the Kwik-Switch. I use it about once a week. For all the more I use it I couldn't justify the added cost of tooling. You can pick up R8 stuff used everywhere.

I made the collet close for my lathe but it is the old hand wheel type. I don't use the close that often.

I am still old school and I have never used a CNC machine. I am not sure how they would work in a small shop when no two small jobs are the same.

I don't need a DRO for mine but I wouldn't mind one. The cross slide is true and I took the time to properly align the head stock so it cuts very true. I always use a dial indicator on the carriage because the markings on that wheel are always useless, if I need to be within 1/2 thou I'll put one on the cross slide as well. I have a few products out there that require for me to make many parts on the lathe so the collet closer is going to cut the run time in half.

I've always run manual machines but the 2 axis CNC is the minimum for some of the work I want to do in the future.

The clearance angle is pretty tight since I cut the squish at 2deg and I'm using a triangular insert bar.

Good idea about flipping the bar over and running it on the backside. I wouldn't have to reverse the rotation though.

Don't cut in reverse if you have a threaded on chuck. You run a risk of having it unscrew while you cut.

D1-4 mount.

Camlock chuck mounts for the win. Some of the later 10" SB lathes had camlock mounts, not sure about the 9" models. It's the one thing I really dislike about mine.

My new South Bend just made it home and in the shop.

 

[w8ye]

Very nice

 

[procarbine2k1]

That one has the "back gear" gear reduction setup accessory that a lot of them did not have.


There was also a cast aluminum cover for the pulleys in the headstock

I am going to Ashland in a minute.. but I am going to make tracks back home and hopefully have some free time today. I would like you to check it out, and I have a real sweet looking AS shirt from the gtg too waiting on you. I will give you a buzz in a few.

 

[srcarr52]

It's not a lathe but I came home with this guy yesterday.

That's a big one like a #5?

Partner 03 Milltronics Centurion 1 controls, I think it weighs 4700lbs.

Very nice looking mill, its been a while since Ive spent some time with one of those.

What are you guys thinking for a tool post? What supply shop have you had good luck with? I am out of the loop, but I have purchased from Shars before, but again its been a while. I found a wedge post with a few holders on Ebay new, but have seen mixed reviews. It has a lantern post on it now, which is alright but will be going a different direction for boring. Pardon my off and on absence with AS, I will be spending some minutes, hours, days, possibly weeks on practical machinist, excellent site!

What size lathe. I have an import wedge style BXA size tool post I'd sell ya cheap. Check eBay for cheap tool holders.

I'm using a Shars QC on my 9 X 20.......

He needs an AXA, he has a 9" South Bend.
