What Did You Do Today (2016)

[Anthony KnightsParticipant @anthonyknights16741]

Carried on with cleaning up the workshop and came across this behind some cable reels. My first lathe????.

The picture shows it after I cleaned it up. Also stripped and cleaned the drill. New grease in the geabox.

Reassemble and test. Working fine.

Need to find the tool rest or make a new one.

Hi John,

I have got a tripod but it isn't always easy to use in the confines of my cramped workshop. You should have seen it before I used Youtubesshake reduction facility.

I think the unatural movement the Youtube thingy produces can make the queasiness worse.

The answer for you may be a monopod?

[Ian S CParticipant @iansc]

Was there not an article in MEW about a camera support, don't remember much abutit, I think it either mounted on the wall or ceiling, so it could be swung out of he way.

Ian S C – not sure about an article in MEW but John 'Doubleboost' built one which he shared on MadModder and probably in his videos (regret I can't quickly find that thread on MM though).

Perhaps you are thinking of Ouballie's 'SkyHook' posts on the forum

Well the refurbished Super 7 arrived from Myfords yesterday and I am very pleased, both with the lathe and with the service. The Lads loaded my exchange machine, carried the new one in, refitted my old motor and bolted and levelled everything up. All I had to do was make the coffee. I know Myfords are not everyone bag but if like me you have had one for ages and you feel it's time to upgrade it is cheaper than you think. I got a reasonable price for my old lathe and as I had an inverter drive and motor which I retained along with the existing stand and chucks all this gets set against the list price of the package which makes it a lot more do-able. Considering I now have a fully reconditioned version of my original lathe with the addition of power cross feed and quick change gearbox at a manageable price I feel it was a good decision.

regards Martin

[NJHParticipant @njh]

Good oh Martin

Nice to hear your satisfaction with the brand and service. I have vaguely considered an inverter drive for mine – one day maybe!

I really did feel slightly sick after watching the first one, so I won't be watching this one.

[JohnFParticipant @johnf59703]

Hi Norman, glad your pleased with the new lathe, I recon they are one of the best small machines available, only crib is the headstock bore, now addressed on the late machines and apity they can't be retrofitted.

Andrew I just fitted an inverter drive to mine after 40 years- wonderful should have done to years ago !

Teaching children – When I was at school everybody learnt by repeating stuff, tables , spelling, etc. The commonest question was " what use is this to me ?" I think this is the teachers and parents job, explaining what use and interest the subject has. As an example " what use is knowing about triangles going to be ?" Mention 3,4 ,5 triangle will be useful if you are going to build a shed.

You are so right. If a teacher cannot explain what he/she is teaching ……….. I met this with maths throughout my education. However some teachers were quite interesting, I was taught calculus very rigorously by a history teacher who treated the subject as a philosophical exercise. Thinking back I realise he knew the subject very well and was a very good teacher (probably wasted on us, particularly me who spent a lot of time looking out of the window).

Sorry I have been mugged by the dating system again (twice now). This was a thread belonging to January. Is it possible for me to delete this post?

Not really, only if what was written was truly objectionable, otherwise it's written on stone.

Not actually coming from anyone official on the subject but that's how I understand it.

…'If a teacher cannot explain what he/she is teaching' ……….. I met this with maths throughout my education.

​Same here; Maths was the bain of my education, yet I ended up in Engineering in one form or another all my working life.
​I can remember to this day my secondary Tech. school maths teacher, more than likely long gone now, he used to write the maths equations / algebra on the board, write one example out then set a series of questions for homework… no explanation as to what the process / methodology was… & when I raised the question 'sir, I don't understand how you did that?… was promptly answered with an accurately thrown blackboard eraser, accompanied with the comment… I've just shown you!, it's easy!… for him maybe… Ahhh the good old days.

I put the 3" Abwood vice back together today, and am very pleased with it. Here's a photo showing it in its new forest green attire.

Very Classy, what kind of paint did you use, if you don't mind?

Michael W

[Mike E.Participant @mikee-85511]

Hi Michael,

The paint is called "One Shot ", its a sign painters paint. You brush it on, "and let it self level". Don't go back over it with the brush once you've applied it to an area. Attempting to brush after the paint has started to skin over will result in a poor finish. Two coats are rarely needed. I have used this brand of paint for all my small tool restorations, and it is quite durable.

[Bob RodgersonParticipant @bobrodgerson97362]

Here is the last part of the video on fork restoration. Get the sea sick pills out.

Was highly gratified to see my Arduino driven rotary table article appear in the new MEW.

[MuzzerParticipant @muzzer]

For those who are interested in using Fusion 360 for CNC turning (including the Tormach Rapidturn presumably), there are some rather helpful videos from Mike Mattera that he's just posted. I really like his teaching style. Previous videos cover probing and 5-axis toolpaths.

[Andy HoldawayParticipant @andyholdaway]

Carl, really enjoyed your article on the rotary table, and am considering doing the same. The number of stepper motors, however, appears to be a minefield. I have been unable to find a motor that exactly meets the specs of the one stated in the article.

Could you advise where you obtained yours, with a full description of the motor if possible?

Many thanks,

Andy

[Carl Wilson 4Participant @carlwilson4]

Thank you Andy, really pleased you enjoyed it.

I got my motor from Zapp Automation. No links to them apart from liking their products.

Of course it depends on the size of table you want to drive but this is what I used:-
http://www.zappautomation.co.uk/electrical-products/stepper-systems/stepper-motors/nema-23-stepper-motors/sy57sth56-2004a-nema-23-stepper-motor.html

You could use a motor removed from an old piece of equipment.If you know the number of degrees per step, you can modify the software to suit, as I explain.

The motor I used is the double ended version of the one above. I intended to fit a handle for manual operation to this, but I need a hard to source special tool called a round tuit.

The motor is 2A 12volt 1.8 Nm holding torque Nema 23 frame.

Thanks again for the kind comments. You should definitely convert. It knocks counting handle turns and missing the right hole into a cocked hat.

[Andy HoldawayParticipant @andyholdaway]

Thanks for the info Carl, I'll let you know how I get on.

I'd better get my finger out and stop messing about to get my dreams finished.

After a not that good year health wise was at the Hospital and was told I had Lymphoma but is treatable there are possible complications caused by other things.

I have nothing but praise for all the staff at York Hospital they have been angels in my time with them despite what certain moaners and groaners say

A few patients and family want 5 star service if they require that go private they will be surprised at what they get.

I'm more upset as haven't to drink beer now.

That's my Victor Meldrew bit done.
