Stuart........ who really doesnt need another level................ or does he?

course you do!

I will go and have another look. I have 2 different levels so I don't need one, but I have been chasing something else for a long time and it's always on there the cheapest.

We can tell Eskimo is not level headed, or is he,now with 3 levels

HI,
Yep You can put the Cover back on and then You can come and do Mine LOL. Seriously Well Done thats Good. So not to Time consuming then ?. Yes the day Temperature will certainly change it. I have two Fibreglass Corrugated Sheets in My Shed on Sunday the one above the Lathe and Mill got covered it Chrome Paint the other will get done this Weekend when I get some more Chrome Paint. have You considered Whirly Vents on Your Shed Roof ?, I put two on My Shed Roof and it has certainly made the Shed a lot Cooler on Hot Days.

Out of Interest what Chuck were You using to do this 3 or 4 jaw ?. In Regards to Mail Forwarding Greg Q pointed this one out to Me fairly recently USA Address & Mail Forwarding I haven't used them as Yet. I gonna Buy another Level Myself, I have two already a Digipas Electronic one it works well. The other I got from Shars it will equalise (isn't their another word ? for that I can't think of it though.) to the Temp in the House but I haven't yet been able to get it to equalise to the temp in the Shed, perhaps it needs more Time than what I have given it.

Did You see these Levels eskimo ?[ame="http://www.amazon.com/TTC-Precision-Machinist-Spirit-Level/dp/B0057PP7YC/ref=sr_1_8?s=industrial&ie=UTF8&qid=1328000207&sr=1-8"]Amazon.com: TTC Precision Machinist Spirit Level - Model: SL-279 SENSITIVITY PER 10": 0.0005" (10 seconds): Industrial & Scientific[/ame] ,they come from France according to the Travers Website they also have a 20 second to the foot one. I am Tempted, but the Starret levels look to be better made.

P.S. I meant to Say if Your Shed is getting quite Hot on Hot days perhaps the Whirly Vents might be a cheaper option than an Air Conditioner. Although than Air Con will give You a much stabler Temperature. My Shed was getting to far to Hot on Hot Days. Thats why I went to the Whirly Vents which made a big improvement. Now I am in the Process of Painting out the Skylights until I get a chance to change them to Corrugated Iron.

Out of Interest what Chuck were You using to do this 3 or 4 jaw ?.

Due to lack of knowledge,would it be of any importance if a 3 or 4 jaw chuck was used for alignment?

HI,
In My Opinion Yes and No. A Cylindrical Workpiece in a 4 Jaw Chuck can be set to Zero TIR. With a 3 Jaw Chuck the Work Piece generally can't be set to Zero TIR. The reason being is that 3 Jaw Chucks aren't as accurate a 4 Jaw, because a 4 Jaw allows you to Adjust each of the Jaws independently it is a far more accurate Chuck.

In answer to Your Question You could use either after all both Chucks are going to be used on the Lathe over time. Using the 4 Jaw though should enable You to set the Alignment up more accurately though than the 3 Jaw providing the Workpiece is the 4 jaw is set to Zero to begin with. Perhaps someone else can explain it better than Me.

I was asking the Question about which Chuck He used just out of interest. All eskimo can do is Align his Headstock as close as possible. Once He has done that He just has to put up with Temperature changes the small variation in TIR when changing Chucks just like the rest of us.

I am glad He didn't have to much Trouble going about the Process.

Once he's taken a cut it doesn't matter how it's held. I think that's what PC is driving at.

Hi Steran

I was going to install plastic roof sheets to save on power..might not now
never thought of whirly vents...I might give one or two a try.

I was using a the standard 3 jaw feurda chuck that came with the lathe

No I didnt see them...but they are dearer than that Starret

The level has been shipped direct to me so Amazon says..at AU$92.26
No need to use the US address. But I have used it for telescope stuff from US as the dealers wont ship Celstron, meade and some other stuff direct...so I use the us address and all works out about the same as if the stuff was shipped straight to me...but its still a whole lot cheaper than what they want here for the same stuff

Hi Graham

At first I started out going round in circles as every time I made an adjustment to the set screws to swivel the headstock it didnt seem to want to go where I thought it should have.

I then deliberately put it out in one direction..this way I knew that I needed to keep moving the headstock in only one direction...this removed a tendency to ask myself..which way do I now need turn that set-screw...kept moving it bit by bit using RDM until it got close ...then watched for movement in the head stock when tightened it all down..made allowances for this and tightened it all up when I thought it was close to the mark.....

did a test cut and still half thou smaller dia at far end...closer than what it was

put bar back in exactly same spot ( bar was indexed to chuck) and did another small adjustment...pulled down head and noted how far head altered DTI...made allowance and did test cut...still 0.00025" (I reckon) out...still could be better I thought

Repeated previous step and a few more times making ever increasing smaller adjustments ....creeping up to its final resting place so to speak

The DTI was only moving at 0.001" at the far end of the test bar which was about 18 inches from the chuck in these final adjustments

when it hit 0.0001" on a test cut I thought that was reasonable.
