Can you post a picture of your metric chart as well please

I'm not sure how I worked out where the Z goes. But on my lathe the Z gear goes on the input of the QCGB. Of course now you have me wondering lol. I don't recall cutting any imp threads so I can't really say.
Only M feed is used for thread cutting(S engages the power feed shaft and disengages the leadscrew). I/II are different gears. So if you wanted 19 threads per inch. Find 19 on the chart to the right of either MI or MII in the top or bottom of the chart(in this case MII on the top chart), then go up and get your other two gear settings(in this case C3) and your Z gear number (in this case 38), then set up the gear train with either the 48 or 24(in this case 48) and the Z gear
Make sense?
(oh great you can do 19tpi in MI C3 with a driver of 24 and a Z of 48)
Still making sense?


That's a great looking bottom on the oil pump on your mill lol

The picture on the side of the chart shows where the Z gear goes and also the others.

Yes but do we just assume that its drawn the right way up?

Yours has a imp leadsrcew right Dave? Do you have change gears for the bottom of the thread chaser?

Stuart

I really am thick sometimes... Just excuse me while I go get the hammer and readjust my brain

Thanks gents, makes perfect sense now!

My metric chart looks much like Daves, except I don't have any empty spaces in mine. And yes, its a 127/120 compound gear, the gear from the spindle drives the 127, the 120 drives the input to the change box.

I know, fantastic craftsmanship on that one. The guy who made that must be some kind of genius

Back to oils for a moment, ISO68 oil - is that in all 3 spots? Or do you run something lighter in the headstock itself?

Oops sorry forgot to check, its been a busy day.
I do run the same oil in all three. (but thats not much help)
Off to the shed brb

Well that was a piece of luck, I had left the roller door open!!

LOL, you could be right there and won't know until you try them.

I have cut a lot of metric and imperial threads with mine and the diagrams and threads have turned out right.

As for the thread chaser, the imperial version only has one gear and metric you don't use it. I think this is simpler than the metric lead screw where you have to change them and if I bought a bigger lathe I would want imperial lead screw.
Did I give you the link to the guy that modified the metric thread dial to take all 3 gears and was adjustable up and down to suit any of them?
If not here it is.

I sure do know the place! Thank you kindly sir....

Now that I think about it the metric thread would be wrong with the 24/48 gears in the wrong place as well. So we must be right

You have a chart for the different pick up numbers for the different tpi?

I've seen that link, its on the list lol I have to mod mine as the other gears lock the shaft when fitted.

Ben,
I think they sell way oil in 5l containers now.(although you would have some already for you mill?)

Stuart

Hi Stuart,
There is a chart for drop in numbers, but I haven't got one on the computer to show you.
The chart was originally mounted on the left side of the carriage? Why I don't know, as it would be easily scratched by swarf on that side and I needed to bend down and look around the corner to see it on the opposite side to the dial?

Dave

Dave,
I was just making sure you needed the drop in numbers(which of course after thinking about it a little more, of course you would), its be more than a few years since I used a lathe with a imp leadscrew and I don't believe I cut anything threads on it.
On my lathe the drop in numbers are on the change gear cover on the same plate as the other feed info.

Yep, they do sell it in 5 litre containers (Tonna S 68 at least). Still got a bit left, although between flushing the mill oil passages, a bit of a leak in the oil pump reservoir (fixed now!), and donations to a mate, not as much I should have after less than a year!

New guy here with an AL320 H&F.

Building a cnc AL320, which now runs.


Seems like the attachment isn't working.

How do I attach a picture of the lathe?

Any suppliers in Perth for way oil?

Mark

Welcome Mark. I thought we had a sticky about posting pictures, but apparently stickies have been confiscated. Maybe we were bad .

Anyway, there are three ways to do it.
1. Use the 'manage attachments' button. It's below the box where you type your text. The image will appear as a clickable thumbnail below your post. This is the simplest method.

2. Upload them to your album on this forum and link to there. Yes you have an album. Click 'User CP', top left of screen, then in the left hand menu look for 'Pictures & Albums'. Follow the prompts then paste the image code from below the pic into your post. The image will appear full size in your post. The forum software will automatically resize large images.

3. Upload them to a hosting site like photobucket and insert links in your post, much like method 2, but without auto resizing.

I prefer method 2 because it's much less likely that a future traveller, who has done a search for your particular model of lathe, say, will be frustrated by the 'this image has been moved or deleted' icon. We've all been there.

The other thing I don't like about photobucket is images can appear too large for my screen. That means that whole page of posts adjusts to the width of the photo so you have to scroll left and right to read the text. Very annoying. (Dave, are you listening?)

2nd try for the picture.

Thanks Bryan

Mark

That picture came through fine. Welcome to the forum.
It looks like a good project you should start a thread about it as a lot of us here would be interested in watching you progress..
