|Thread: Super Mini Lathe belt problem|
Well as you have mentioned it, yes it is where we are at, however all is not lost in fact it's better than it ever was. Many, many years ago I wanted to own my own lathe, an engineering company were selling a couple of old Herbert's, even though they were well worn and very basic they wanted almost a years salary for them, (I was in my last year of apprenticeship so my salary wasn't great). Move on to where we are now and I can engage a few places who can discuss my needs (wants more than need) and then sell me a new lathe suitable to my requirements. It might not be up there with the best available, but look at the cost of a British lathe similar in function, (say a new Myford) I couldn't justify such a purchase even if I could afford it.
Hopefully the OP will get many years of use and enjoyment from his lathe and he knows that Warco are there to help if needed.

Great work Craig, sounds lovely, hope you get many happy hours flying it.
|Thread: Oh bugger, I told you I was ill|
Love the banter. Hope your better soon mate.
|Thread: HSS or CS taps and dies|
Having read through this thread I will admit that I mostly have and use HSS, I am sure at some point I have broken both CS and HSS through my own fault. I might just give the spiral flute taps a go in the future, I hadn't realised that they would work as a hand tapping tool.
I had a quick look at Presto web site and they are asking to log in before seeing prices or buying taps or drills, do they only deal with companies or bulk orders?
|Thread: indexible internal thread cutting tool|
Yeah I think the tube is made of some well treated steel, the cutter does cut it ok, just that the finish is awful.
I will give it a go over the next few evenings and let you all know how I get on.
Thanks Emgee, I will bare that in mind, it does look a bit on the small side for the job I am doing.
I will have a look at that, currently I have set it the conventional way so that the tip is at the centre of the tube which could well be part of the problem. Sadly the tool holder and insert came with no technical data.
I think your right, the crest does look and feel sharp. I might have to look at the same supplier that Andrew uses. What is that saying about buying cheap
I am afraid that the information is not available for that insert from that supplier. I suspect that the optimal cutting speed for the insert would make internal threading very interesting, although I will see what other suppliers are stating as the best range of cutting speeds for such a tool and give it a go
I am going to see if I have a piece of HSS tool lying around, just in case
Thanks for the quick response Andrew and Mark. The tool and insert was from RDG, in the photograph of the tool used on the suppliers web site it looks the same as yours Andrew, however when mounted it is angled (rotated) so that the head of the tool is about 30 degrees lower than a horizontal position (difficult to describe). The tool is in a fair sized bore and does not apear to be rubbing or fouling anywhere. A good suggestion to try a different material, I will give that go. I will also check if it is full form (I think so).
Mark I thought clearance might be the reason for it but I also thought the insert would have been formed so that the tip geometry had positive (conventional rake).
Indexable inserts were not around when I learned to do this type of thing so I wouldn't be surprised if the poor result is down to poor technique with the tool, I will try small adjustments to tool height to see if that helps.
Once again many thanks to both of you.

I have a query about an indexable internal threading tool which uses either a 55 degree or 60 degree insert as required.
The tool is one of these
The query is this, when mounted in the tool post the tool and insert sits at an angle of tip down giving a very negative rake angle. I could just live with this if I got a good result using it, but I don't.
I recently cut a 1.25 metric pitch thread using a new 60 degree insert, material was a steel hydraulic tube which already had one end threaded with the thread I wished to cut. The finish on the one I cut was pretty awful feeling very rough and having burrs on every crest. Spindle speed was 240 rpm and results was the same with or without suds. I checked that the tool was at 90 degrees to the work piece and tried various speeds, all giving the same result, am I right to suspect the tool?
|Thread: Chester DB10 thread cutting ???|
Without the help from yourself and a few others I would have failed to get a satisfactory result. Of course I will still find a few more stumbling blocks with future projects I'm sure.
Thanks Mick. Hopefully it will get lots of use as I still have a few AA's with regs that do not perform well.
Nice mill well done, I hope it serves you well.
|Thread: Chester DB10 thread cutting ???|
I apologise for taking so long to show the components I needed to cut 14 tpi for. Below is the collection of parts the small item was bought in, the other two made by myself. The solid bar still needs to be parted and faced then drilled and tapped to take the guage assembly but it is very nearly done now as you can see in the photo above.
My sincere gratitude to everyone that helped me to get this done.

|Thread: 2 1/2" Gauge Society Event at South Cheshire MES|
I will try to pop in and say hello if time permits, I only live a few miles away. Hopefully the weather will be kind for you all.

Welcome to the forum Dave Corkish, ignore the Comments from Brian he is in a small minority, the larger group of forum users are often friendly and helpful. I can't help with your enquiry but I hope that you do eventually find the information you are looking for.
|Thread: Help on a Matador four stroke engine build please.|
I have never built my own aero model engine but I have owned a few Laser engines (and still do), British 4 stroke engines, very reliable and fairly powerful.
I can't say for sure, but maybe you could contact them and buy gears from them? Link below
