basic lathe tooling questions for new lathe

[EdK]

I have the same lathe as Bob but I made my own stand. The lathe weighs about 1100lbs according to MSCs specs on it. I have not bolted my lathe to the floor. I used these leveling pads to level it and haven't had any problems with it.

My answer to Q1. I doubt if any noticeable difference in the home workshop.

My answer to Q2 & Q3. Again probably no noticeable difference, go with the most cost effective.

Questions 4 & 5 I will have to think about them

Hang about Bob, others may have a different opinion

Hi
Bob
Unless you are pushing things to the limit you will not notice any differance with the smaller tool size
I use a piston type tool holder and i am very happy with it
As far as parting tools go this is what i use

I use the cheapest tips i can find
Mu previous lathe was fairly large (colchester Bantam).
My current lathe is much smaller so i modified my large tooling to fit , by milling a dove tail in them .
They go directly on to the tool post without a holder.



As far as tips go i would just use the most economical
There are loads of speed & feed charts on the net.
But for home work i would just experiment.
Dont forget carbide inserts like to be worked hard

John, I love the idea of dovetailing toolholders to fit a QCTP, but, one question, Is that a high speed steel dovetail cutter dovetailing your toolholder?
If yes, then let's revisit the newbie's (OP's) immediate (apparently) leaning toward carbide.
Properly ground HSS does a better job in many cases. it's part of the learning curve.

It is a high speed steel cutter (the tool holders have been annealed) but are still tough

Thanks John, I have a HSS dovetail cutter so now all I need to do is learn how to anneal the insert holders.

Here a one way Steve,

You need to get them up to orange heat and hold them there for 30 minutes then let them cool in the fire.
A domestic coke fire would do the job
The longer they "soak for the better"

I cut mine without annealing with a 1 inch cobalt roughing endmill then used a single flute carbide dovetail cutter boh of which I bought for a reasonable price off e-bay. My RF45 Clone didn't even complain while doing it. Some were 1.5 inch Kennametal some were Sandvic 1.25 inch. I plan to drill + tap them for studs + knurled nuts for adjustment. tom

Pictures will be forthcoming, I assume?

Steve, get your shaper working, it will cut dovetails in just about anything.

Ya, Greg, someday. When I get a chance I'll take some pics of what I broke on it with the help of gravity, inertia and stupidity.

Sorry ED I didn't take any pics but check the post for an update the endmill was cobalt and the tools were kennametal and the new ones I did were SANDVIC. TOM
