Thread: TTFN
18/07/2019 20:01:49

I am extremely sad to hear of your decision Andrew, you have been one of the very helpful people that I referred to in the very same thread, your knowledge and willingness to help will be greatly missed by those genuine forum members, hopefully your absence will be short lived. So until your return I wish you well and hope the building of those traction engines continues so that you might share a video of them running.

Best regards,

Ian

I have encountered the odd unhelpful response on this forum but I have received far more genuine replies and offers of help from quite a few members on this forum. Long may the helpful and friendly members continue to out post the not so helpful.

Thread: Different ways of boring a hole
14/07/2019 21:51:48

So Jason, if I understand correctly, the work piece is fastened onto the saddle with a special clamp arrangement, and travels along the bed with your home made tool mounted in the chuck and supported by the tail stock centre. Bore size increased by adjusting the tool. That's very clever, I would never have thought of doing that myself, thanks for sharing.

Thread: Warco Mini Lathe

I would be inclined to try and get it working better before buying anything else. You could buy something bigger and dearer only to find that it too has problems, the experience in fixing it or at least improving the problem will be a skill you have acquired to take with you when you buy other machinery. I have had to make several modifications and adjustments to my Chester DB10 to get it to turn truly parallel and give a good finish. Even now I am thinking of buying or making a better tool post mounting arrangement as this is now the weakest link in it. Once that's done I will look at upgrading the motor.

Good luck.

I don't know a great deal about guitars but that bass looks great now you have cleaned it up Neil.

Thanks, it sounds good too. Very much a 'precision bass' sound If this works!):

Yep sounds very good, nice to have the skill to re-build it and play it.

Thread: Chinese tacho - beware
21/06/2019 21:04:52

Duncan (or anyone else) do you have a link to the project that uses the ardunio to make an accurate tacho such as the one you have made? I was thinking of getting one of the ones on ebay for my Myford mill but after reading your post I guess it was too good to be true to expect a tacho that would work and continue to work for that price.

Does anyone know if there is a tacho that you can buy where all that is needed is placing of the magnet and some simple wiring?

TIA ,

Ian

I'm going to cop some flak for this, but buying a reasonably 'big ticket' item like a Chinese lathe, smacks to me of another example of the 'baby boomers' and yes, successive generations too, selling the world down the river for their own brief amusement (again).

I've been on the Warco site, The Axminster site, and so on, and my finger has hovered over the 'buy' button many times, but I just can't bring myself to do it.

...Ducking and covering.

So don't press the buy button, nobody really gives a damn what you buy, it's your hard earned money, go out and get the best British lathe you can afford if that's what your personal choice is. I hope your driving around in a British made car, hopefully with enough space for you and that chip your carrying around.

Perhaps what they say is true, a Chinese lathe at this price is a kit of parts. Sad though. 1000? years of development of this tool and this is where we're at? Really?

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.

I even won an Ebay auction while I was under lol.

Good job you are OK, might have had a negative effect on your feedback otherwise!

All the best for speedy recovery now.

Love the banter. Hope your better soon mate.

Thread: HSS or CS taps and dies
22/05/2019 11:01:07

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
20/05/2019 21:55:45
Posted by Roderick Jenkins on 19/05/2019 23:52:53:

I use exactly the same tool from RDG. Generally I get good results, usually winding the spindle by hand. Tougher materials like silver steel do tend to have a burred up finish which needs a bit of work afterwards to clear up the crests with a file. I suspect it is your hydraulic tube that is causing the problem. As has been suggested, you may need a rather more frightening speed to get a good finish straight from the tool. Perhaps the in to out reverse method as advocated by Jason may be the answer.

Rod

Hi Rod,

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.

Posted by Emgee on 19/05/2019 23:11:00:

Ian, be aware that you need the designated thread size for each insert as the crest form varies from the small to larger sizes, best to just buy the sizes as needed and you soon build up a number of common sizes, same info goes for different TPI inserts.

Emgee

Thanks Emgee, I will bare that in mind, it does look a bit on the small side for the job I am doing.

19/05/2019 22:30:54

Hi John,

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.

19/05/2019 22:27:50

Hi Emgee,

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 sad

19/05/2019 22:24:05

Hi Nick,

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 wink

19/05/2019 22:06:09

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?

Hello Ian,

That looks like a nice piece of work, thank you for showing us what the collective prodding of grey matter helped you produce as a result.

Regards

Brian

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. wink
