By far the best policy. If it 'feels' right it usually is.

The graving tool 'trick' is somewhat counter-intuitive until you've actually tried (and mastered) it. I don't get quite down to watch pivots though I do build clocks. Even so I do have solid carbide drills down to 0.3mm Ø. The last 'collet' I made was to hold a 12T MOD 0.5 brass gear - 7mm OD...

That could be a useful ploy and I have done something similar - not with tubes made from sheet, but by making 'collets' from Brass, Alum or even steel - particularly useful when needing to hold very small dia. components.

Ah... One of the problems of trying to give advice without really considering the basic knowledge of those asking for it ! I'd assumed that you were already using (at least) BDMS. 'Black Bar' is a different animal altogether, I would expect to take off at least 3mm before I got to a finished...

Not always an easy option. The only steel that is usually supplied 'ground' - and therefore accurately 'round' - is Silver Steel which may not be suitable as stock where En1a, En8 or some other specific steel is specified, though, to be honest, the amount of out-of-round of any Bright Drawn...

Astute of you to appreciate that there could be an issue :) Generally I grip a small pre-machined billet at the back of the jaw carriers but it would depend on the job in hand. If the intention were to hold the work by expansion then I would use a larger 'Ring' on the outside.

For me that's a given 😆 If you don't aim for it you'll never achieve it.

That's precisely the reason that I use soft jaws and machine them concentric with the lathe centre-line each time I mount the chuck. This is even better than using a collet chuck (I do also have an ER32 Collet set). 'Clocking' work in an independent chuck is an art and, unless you have had...

Store it upside down ??

Absolutely!! That's one of the few things that Maggie got wrong :( It's not that councils didn't re-build - they were not allowed to use the funds created to do so !

It's a moot point Phil. As I'm sure you'll appreciate (knowing my previous posts), I could go into great detail with drawings but I'll not bother :cautious:

If your stock is out of round, rotating it in a four jaw SC chuck will have little effect since you will still be holding on only 3 of the jaws. It might be a different one that doesn't actually make contact. It would be possible (though you may have to be very precise with your positioning)...

I'm tempted to respond 'Schnapp' 😌 - since I did the same, but not in fastenings (Toolmaker) but I did work for E.O.French, a fastenings distributor for a while and clearly remember using the 'Blue Book' to determine prices. This was a publication produced by GKN to provide a 'base' price...

Hardly 'recently' -- the one child policy ended in 2013 - 8 years ago - being replaced with a 2 child policy 'if one parent was an only child' but in May this year they went to an 'up to 3 child' policy with no caveat.

That depends ! I have had something similar but it was a packet of 'Haribo' gums - but I'm diabetic ! I would have preferred Pastills :)

I've stopped watching 'The Repair Shop' :mad: The number of times I've screamed at the screen "Stop doing that!!!" - using a one-hand held power drill to put a hole in an item held in the other hand! rather than clamping the work in a vice and using a pillar drill :( Some of the...

Ah - that's where I have the advantage, I had an extra 3 hours sleep last night -- I got close to 8 hours - didn't know it was another day until 10:15 😆

@accipiter : It seems you've missed some of the posts (or mis-interpreted the detail) - the skirting in question is 290-319mm high !! - non-standard in anyone's eyes - and the 'topping' is pre-painted MDF Architrave from Travis Perkins, already purchased.

I've had three blades break over the past four years - I always buy 'Tuff' - and Ian has repaired two of them FOC as is his way. One broke at the weld and the other was elsewhere. The third blade (not broken at the weld) wasn't repaired due to technical issues probably caused by...

That seems very high (to me). The skirting in the photo you posted I estimate to be 135/140mm ~5.½" which is also on the high side but the additional 69mm (I'm assuming Travis-Perkins 19x69 MDF painted Truprofile Architrave) will make your skirting 319mm - over 12½" - as a comparison, the top...
