My First Lathe!

I have the same set ...
Don't over tighten or you will destroy them, they don't need to be armstrong torqued!
Down till the screw stops, then a snug. If you're destroying the Torx, you're over tightening them!
Light cuts and the bars will last you a lifetime, Inserts not so, you'll want to get a better grade.
Of course, as with any cutting tool, always use them as short as possible. (close to holder)
Holden202T, I don't want to be critical, but it looks like you're getting your tool high ... Top of cutting edge should be dead center.
Some people like to use the Ruler method for tip height, I personally hate that technique, I've seen to many chipped tool tips with that method.
I also recommend Aluminum cutting fluid <- Cutting fluid! NEVER use oil for cutting fluid, NEVER!
Oil makes a cutter ride not cut ... Soapy Water is better then oil! (That means NO WD40 or the like)
Turpentine is actually a good cutting fluid, especially for Stainless Steel. You can cut stainless with HSS and Turpentine.
Once a cutter rides, it's junk!
Magnify the cutter edge to see the glare ... Reflection of a dull cutter.
I personally use nothing but Tap Magic ... Love the stuff! If working by hand (ie Taping) you can physically feel the difference!

Re: My First Lathe!
i had to set the boring bar high so it would fit in the hole because its too big, but with these smaller ones that wont be an issue.

Re: My First Lathe!
bit of a side project, never the less, good excuse to part off and bore out some alloy rod!

Re: My First Lathe!
So the boring bars arrived just in time to get the part sorted thursday night so i could have today to put it together and you'll all be pleased to know i finally washed the base part
The welding isn't the best, but i wasn't expecting the cast part to be nice to weld, it worked but its not pretty so i machined it smooth
With all that completed i was finally able to work out where to cut the chopper down to. you will notice there is a fair bit inside the housing still, this will allow me to adjust things later if i decide to go for a different sensor or chopper width. currently its the LS1 configuration which is 50/50 on/off
i need to get some longer screws to attach the sensor for good, but thats about all that is left to do now!
This is a quick scope of the signal from it in the drill!
