Wow thanks jack, I think I saw something like that in the paint section.
As the silicon is for lubrication right? I mean most silicon based lubricants will work right? Because I found like 3 brands of silicon oil.

I like how this guy thinks. Notice how he leaves the work in the chuck to keep the accuracy.

One thing I like about Sherline is they have a relatively long bed, the power isn't plenty through, I have a 500w brush-less motor on my SC2
Looks like I'll have to pay that 90 euro dial if I don't want to wait

OH MY GOD THE LITTLE WHEELS ARE MOVING OF THEIR OWN VOLITION!



... must be because he is listening to Queen.

the power isn't plenty through

You can see the rpm visibly slow down as he starts drilling the steel...

Is that the CNC attachment for the Sherline products? Very nice actually...
(If I saw them earlier it would be a little harder to choose from Sherline and Sieg)

I'm sure there are plenty of kits available for the sieg too... but unless you are going to be mass producing, or making extremely complex parts, I don't think CNC is worth the trouble.

There are plans, I know. But complex because the lathe it self wasn't designed to have a CNC mod (Sieg doesn't has a CNC kit for it's lathes or mills), the Sherline in the other hand looks like the CNC mod was thought during the design, therefor easier to convert to a CNC lathe later (I think )

[jackssmirkingrevenge]

I don't think CNC compatibility was planned when the Sherline was originally designed either. It's just that they went ahead and made a decent kit for it, taking advantage of the fact that it's so modular to begin with.

I had contemplated CNC converstion but found I couldn't really justify the effort or expense. Plus there's something therapeutic about turning the little wheels, I don't want to give that privilege to a computer!

[wyz2285]

Can anybody tell me the name of each of these blades? And witch should be used for witch cutting? I googled lathe cutting tool types but didn't found much, only the name and function of 2 or 3.

[dart guy]

i wish but im not sure i got a wood lathe that works woth almost anything but i only know how to use certain tools

[jackssmirkingrevenge]

Here's my amateur perspective:

1 is a boring bar - not because it's not exciting, but because you use it to bore holes (parallell to the lathe axis)

8, 9, and 10 are the ones you're most commonly use for normal cutting from right to left.

2 you're use if you're cutting from left to right.

5 is for cutting threads.

[wyz2285]

Well Thanks jack
Found a page with some tools with diagram and description, 4 and 6 are for cutting grooves, 3 and 7 are for edges.
11 should be some short of boring bar too it has a round body as 1

[jackssmirkingrevenge]

3 and 7 are for edges.

I just swing the regular tool around

These days this is the tool I use the most, with replacable carbide inserts:

[wyz2285]

Yeah I thought these ones too, but aren't sold here, I have to order them and things gets expensive from there...
Edit:
First time turning used a 70mm long 75mm dia aluminium to do some experiments with the tools and to see what's the best cutting speed and stuff it looks so much better than what the drill press did (witch it should, considering the it's 10 times more expensive )
