The new lathe

[Johno1958]

It arrived.
I got my lathe mill setup now (finally) .Not bolted down yet as I may want to move it a little. Now to make some stuff. First of some spacers for adjustable tangs on the live center and drill chuck tapers . Found that out the hard way .
Cheers

Top slide backlash was bad at about 3mm but turns out bolt was loose .

John,

Like your loose bolt, it would pay you to go over the whole of both machines with a few spanners and hex keys, it seems the Chinese haven't learned how to use torque wrenches or white knuckles. Plus make sure you get plenty of lubrication into them, looking pretty doesn't stop the machine wearing out, lubrication does.

For a general rule, ISO 68 for slideways and ISO 32 for everything else, including gearboxes, unless your manual tells you otherwise.

Just enjoy your new found pastime.

Checked and oiled. I used some iso 68 hydraulic oil with a little stp in it which I read about . I can't seem to buy way oil here in Bendigo in small quantities . Did some practice cuts and it seems to cut very nicely . I'll find some easy projects to do and then try a wobbler.

Cheers
John

From the photos,it looks like you have the sieg sc4 lathe and sx2.3/2.7 mill
is that correct.Keep posting.I did a thread on the lathe and I very happy with it
I thought the power cross feed would be the bees knees but I hardly use it
I did make a carriage lock (very necessary) and a carriage stop (helpful)
If you have any ideas for improvement then let me know and any questions
just ask. Regards barry

Thanks guys.
Yes I will have to make a carriage lock Barry .Did you document how you done this on one of your threads. I have the cheaper mill an x2.7 .Not as powerful but seems to cut well. I have fitted a magnetic dro from assee.com using touch dro from Yuri's toys and it works very well.I do have to make a better tablet holder .I'm using an elcheapo of ebay which I plan to modify .
Cheers

Barry
A loose tee handle for the carriage lock. When you removed the bolt does the assembly underneath stay in place ?
Thanks John

Hi John,

There is a carriage lock on the SC4. It's the 3rd capscrew from the right on the right hand side of the carriage in front of the v-way. It's awkard to get at and use and needs to be well tightened down to be effective.

Hi John,
I see you have an X2.7 mill. I have an SX2.7 and it has a peculiarity which I'm not sure is a fault or a misguided design feature.
When I use the handwheel on the side to lower the quill (without it rotating) the handwheel rotates a few degrees after the quill hits the baseplate. This means that the drill bursts through at the end of a hole. It can also cause chatter as the quill can bounce up and down.
Does your machine do this?
Alan C.

 

[Johno1958]

No Alan I have not had anything like that happen at all.I haven't used it much for drilling as I have a small pedestal drill and I haven't need that much precision yet.
As for milling, it quite happily chews through stainless (unknown grade) but for the food industry . key steel . aluminum 6061 .7045 without chattering. I don't take very deep cuts though .
Cheers

Hi John!
I bought exactly the same lathe, a month ago. It seems very accurate and steady for its price, so I am very happy with it!
The first thing I changed was the toolpost, to a Soba Small quick change, with 8 adjustable toolholders (can´t have too many of them..). I,ve first have to make a new centerbolt and a nut for it. Now, it feels like the lathes at work(but smaller)!
Next project is installing a cooling attachment, save HSS tools and drills a lot, and a must when cutting deep grooves and parting off with HSS parting off blades.
A 4 jaw independent chuck is ordered, and definitely very useful.
Regards Pontus

John,

I just noticed your post re not being able to buy Way Oil. Minitech in Canberra have Mobil Vactra ISO 68 Way Oil in half litre bottles, and they can post it to you.

Hope that helps,

Cheers
