I think that the abrasive drop saw will cut quicker through a 25x25 2mm square tube quicker than a bandsaw but the bandsaw will win if cutting larger solid material.
Aside from the speed issue is...

I am always interested in new ideas and to see what other people are making. Just post it and see how you go.

Hi, Trev, Acording to my books you need a Titanium Carbonitride coated cutter and buy comercially pure titanium with a hardness of 140 to 200 BHN.
This is about the hardness of D2 tool steel. ...

Did not appreciate the moving around of other peoples posts.
Thread was screwed up as a result.
If a poster wants two threads running at the same time then that is his buisness and choice .

Have seen a good wood lathe on Evil bay. A solid Hyco cast iron gap bed model , with big disk sander & table 240v motor , starting price $800. buy this and do it up a bit.
Would be miles better than...

OK fellars I'll be the first one to , hot insert into the kill zone.
Pun very much intended!
Looked at your spindle drawing and I dont think many will have a lathe big enough for the job . ...

Sounds like the price quoted is more about making you pay for the time lost on thier normal production contracts than the actual cost of the custom job.
Polishing stainless is not a great deal...

If the problem is infact the lathes small size then there is one other thing you can try. Purchase a " knife edge syle insert " Its an insert with a very sharp edge raked back into a deep chip...

It is common how many tradesman don't know how to sharpen a drill even roughfly.
I was watching an aleged roof plumber erecting an awning at my house when I saw him trying all these different drills...

It is more about the angle of the tool holder in the tool post than the insert itself.
If you angle the insert too much to the left the tip starts to bury itself under the cut if you angle it too...

Yes Pipeclay I am taking a guess at what I think he is doing wrong.
I dont want to pressure anybody for answers they may not have and make anybody selfconsious or anything like that.
Most people...

Its not a clamp perse , its a panel lifting rack.
It is used with an overhead hoist to lift heavy panels on and off wood working machines / manufacturing lines etc.

1/ Coated Carbide inserts can machine at many times faster spindle speeds than HSS so I think you should increase spindle speed a bit at a time to find a good speed .
2/ You are most likely running...

That is real good , .001mm is nothing . The .001 inch (.025mm) that I get on my lathe has a component of flex in it because of the smaller weaker headstock arangement . Your lathe is much stronger...

Thats good to hear. Just make sure you dont have the power feed shaft turning even though you are not using it as it is dangerous . Clothing can get caught up in it. Always select neutral position on...

Dear GJR, First I need to know which feed you are talking about.
1/ Are you trying to engauge the half nuts to start cutting a thread ( lever to very left of apron ).
2/ Trying to engauge the...

Dear Ashore, My lathe is too small to use negative rake inserts well but I have heard from other people that soft materials buildup less on a negative rake insert than a positive one . So that may be...

Thanks Trevor, Glad to help if I can. At 3 HP 3phase unit your lathe could handle negative rake tooling and inserts. However if it is an old lathe then I would test for any movement in the spindle...

Selection of inserts is a complicated issue and takes a bit of time to work it out. A Sandvic Coromant Turning
tools catalogue helps a lot in making the right choice.
First off if your lathe is a...

Ken, Mild steel is also not the best as it is too sticky to machine smoothly and will build up on your tooling cutting edge. Also its soft and will distort under pressure more than better steels. You...

Its a bit more complicated than just the thread selection.
If you buy a lathe with an Imperial lead screw then you will only have ( or be able to fit ) an Imperial thread chasing dial and the same...

Jim, You can rotate the head 90 degrees and reduce the height by about 400 mm .
Also you could unbolt it and lay it on the table for more head room, strap it down though as you dont want it falling...

If the new motor also produced unacceptable vibration then I would say that the manufacture has not ballanced thier armatures after they have been wired.
There is a lot of lacquer , copper wire and...

Graham, It is not as big a problem as it first appears. There is lots of room for swarfe to settle down away from the gears. Lathes dont move around and jump up and down like cars. So the swarf will...

The reason you use a hydraulic oil in the enclosed head /gearbox is that it will not " suspend " fine metal fragments as the gears turn and cause extra wear. It lets them fall to the bottom straight...

Thanks also, very helpfull post.

Thanks for the help, Newcastle saw works got two for me a 18 tpi and a 5/8 tpi Bahco cost was $42 each, pick up. Does this price sound right?
Does anybody get them cheaper and if so, Where?

Most smiths use a hot caustic bluing solution.
Caustic soda.
Sodium Nitrate.
Sodium Nitrite.
Disstilled water.

Use in an enameled or black steel vat.
Heat up with LPG ring under vat....

George, you will not get , precision and rigidity for $3000 in a Chinese made lathe. They work OK but usually need some work to fix things that are not right. The stands on the cheap lathes are...

Hafco dont supply a Bi-Metal blade for this saw only the bigger saws.
They did tell me that some companies do make bi-Metal blades for it but could not say who.

Could anyone please advise me where I can buy Bi-Metal bandsaw blades for a Hafco BS-5S in Sydney/ Newcastle area.
Which kind and TPI would be best to cut 303 stainless from 25mm upto 75mm round...
