Thread: indexible internal thread cutting tool
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

Nice compact reg tester Ian thumbs up

Edited By Mick Berrisford on 03/05/2019 09:04:40

Thanks Mick. Hopefully it will get lots of use as I still have a few AA's with regs that do not perform well.

img_20190502_180345.jpgI 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.

Ian

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.
26/04/2019 21:24:40

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

Duncan Thanks for the tip, will give that a go.

Jason I love that engine, just to give an idea of the size, what diameter is the fly wheel?

Do WM have a website? I have googled and come up with only one address that is actually Walker Midgely and that returns a bad page??

Thread: Soba rotary table
13/03/2019 20:04:58

I have seen lots of the things you have made, so in the right hands they're very useable.

Thanks Jason

13/03/2019 18:29:17

Does anyone here use a Soba roary table without any issues? As already covered it depends on the level of accuracy the user is trying to achieve but it would be interesting to hear from owners of such tooling.

12/03/2019 20:14:12

I don't think I will ever have to worry that a shaft or bearing face is one hundredth of a millimeter out, and if I did I am really sure I don't have the time, equipment or skill to improve it, so maybe that vertex would be a good item for me to buy.

Ketan, do you sell Vertex?
