Is your concern about backlash, or just taking some weight off the drive system?

Arrange for the weight to run along a roller-track of some sort to keep it from swinging, but still free moving?

Thanks, Martin … I will have a look

My own ‘familiarity’ with Autocad goes way back to the early DOS versions; and I still struggle with most of the modern GUIs

I like the ability to do 2D CAD with just the drawing on-screen and all the ‘buttons’ on the edge of a digitising tablet,.

… it’s probably just nostalgia



Ref. **LINK** :


If you do take a look at MoI and you're not sure how to use a particular tool, simply select that tool and then click the '? Help' key on the lower/right area of the screen and MoI will display specific information about it along with examples of use.

Here's the second part of me constructing a bevel gear.

Hi, Michael.

MoI doesn't 'clone' Autocad commands, or even look similar, but it would compete very favourably in functionality. It is much more powerful than a first glance might lead you to believe.

I'll include a (slightly rambling) video of me constructing a bevel gear. I don't suppose I do it in a very efficient way, way, but it shows a few of the tools in use.

MoI will import these file types:

OpenNURBS 3DM, IGES, SAT, STEP, Illustrator (.ai & .eps), PDF and DXF.

MoI exports all of the above, as well as:

I often mention MoI when these questions arise, but seldom get any feedback. Maybe the reason is that MoI looks a little simple at first sight. However it is a powerful package and isn't too bad to learn. Many of the other CAD systems can be hard work and unintuitive in how their toolset works, so that's why I don't use them, even though ultimately, they may have more features.

I'd say, give MoI a try.

I use MoI. Here's a video I made a while ago that shows some of its features.

It can export to DXF, PDF, IGES, STEP, STL and quite a few other formats, it also has dimensioning now.

Looking at this video, it seems to be quite easy to do. smiley

It sounds good to go to me.


Thread: CNC Lathe Scratch Build

Wouldn't a detent arrangement be easier to make?

What would make me think twice about using a Hirth coupling is how many faces need to be in simultaneous contact when indexed and how feasible it would be to machine the coupling to the required accuracy.

Because of its design it seems to me that the Hirth coupling is self-centring, so if used with a close fitting bearing there could also be issues with binding whereby the coupling can not fully seat because it's restrained radially by the bearing.

Still struggling to know whether you actually read the link that I posted, Ady

... I think we’re probably ‘on the same side

... but perhaps not ‘on the same page


Classic! As Ady knows exactly what he means by 'it', he hasn't realised his post can be read in entirely opposite senses. I do this too, often finding people responding to what I said rather than what I meant, oh dear! It's hard to be clear. However, judging by Ady's 09:17 post, Michael is probably right about being on the same side but not on the same page!

It hadn't occurred to me before reading Michael's link that decision makers would be stupid enough to delay climate change counter-measures as a result of assuming net-zero will achieved by applying technology that doesn't exist. Yet it seems to be true! Was it Saint Aquinas who prayed for the gift of celibacy, but not yet?

I'm optimistic energy needs can be met with a combination of Green technology and relatively painless societal change. But that's of little value unless global warming is also controlled. I'm reminded of the boiling frog experiment: when frogs are gradually warmed up in water, they cheerfully stay put until cooked. So it is with people: we aren't good at managing risk and particularly bad unless problems are bleeding obvious. Very inclined to believe slow change isn't happening.

Many examples from history. Although medical research clearly indicated by 1930 that smoking is a major killer, tobacco companies successfully delayed reform by arguing inadequate proof, paying for confusing counter-opinion, fudging statistics, claiming freedom of trade, bribery, lobbying, and banging the personal freedom drum. We're all guilty, and maybe it was for the best anyway. I see advantage in a product that collects a huge amount of tax from working age people and then dramatically reduces the pension bill by bumping them off! Can't see any value in long-term global warming though - only chaotic change.





Are you serious?

Looking at Peter Greene's graph I must be particularly dense this morning, it is peaking around the 6000 mark, I don't know what the UK figure were on the first day or so of roll out but for some time now we have been in the hundreds of thousands per day, over half a million at times, someone put me out of my misery please and explain where I am going wrong in my interpretation, surprised no one else has not commented which makes me think it is me.

Bill D.

Yes, now you point it out, at around 6000 jabs per day, it would take over 3300 days (9 years) to administer the 20,000,000 the government says it has already given.

There must be a simple explanation to it. rainbow

The rumour is that furlough will be extended until the end of June - Hopefully then, the war will be over by Christmas!

Thread: A milling anomaly
25/02/2021 11:59:26

I've had this problem with smaller diameter screwed-shank cutters too.

I think that due to the small diameter, there is simply not enough torque generated during a milling cut to keep the collet screwed tight to the cutter and this is exacerbated by the vibration of the cutting action. The problem is far worse if the cutter shank is below size or the collet is a loose fit.

My solution is to leave the collet carrier slightly loose, screw the cutter in hand tight, and then nip-up the carrier until it simultaneously clamps the cutter and fully seats on its registers.

My wife and I were contacted by our respective surgeries by phone for our jabs and had them last Friday and the Friday before, we're 69 & 70. Missus had quite bad reactions, myself not so bad, to the Tizer vaccine.



That's got to be the best typo/joke in the history of the internet.

Can't stop Lol-ing yes smiley

Did it affect your appetite as in 'Tizer the ..... '


Certainly increased my hunger to find out more about it!...wink

..and it seems to be as good as anything else out there. gift


Live long & prosper. rainbow
