Dave,

I think you've cracked it.

I never considered that it might be stainless, but the symptoms were as you describe.

But why would the choose stainless with all the added cost, special welding, etc. And then powder coat it.

I suppose it helps justify the price!

This is a modern bed costing thousands.

The trunnion I was drilling is 13mm thick and I can't see any good reason for it to be anything other than bog standard MS.

I am told that the steel is manufactured in Poland, as is the bed.

Maybe there is a "special recipe" for bed steel but why go to what must be additional cost?

I volunteer with REMAP and was recently modifying a fully-adjustable bariatric bed.

The modification required drilling a couple of clearance holes for 10mm bolts in the 13mm trunnions for the bed actuators.

The holes had to be drilled with hand held tools as the bed is large and unwieldy.

The pilot holes at 5mm and 7mm went well using HSS bits.

When the 10.5 mm HSS drill was tried in the first hole it smeared and raised a large burr on the surface, as well as wandering off centre by a good 3mm.

A cobalt bit was tried next with no more success.

An end mill did not succeed.

I finally touched up a carbide tipped masonry drill on the green wheel and got through. Luckily the job did not require precision!

I talked to the bed manufacturers' representative who told me that the steel is notorious for unpredictable properties in his industry.

Must have been slag or stainless inclusions or what?

Couldn't give a tinker's curse about minor infractions of issue numbers, infinitives, typos and other non-damaging errors.

I await the home made nuclear reactor articles with interest.

Now there's potential for errors that matter!

But orphan apostrophes are beyond my personal pale.

Which model do you have?

About deal, that I first became interested in about 60 years back when I read "Bevis: the story of a boy" by Richard Jeffries.

My search came up with this:

It is still my favourite book.

matt sw - here you go.

Malaysia, not China. My duff memory!

Mine arrived from China well-packaged and in 12 days.

£26 all in as I recall. Couldn't buy the materials for that.

Runs perfectly.

Well, I did ask!

What a range of opinion, expertise and discussion.

Thank you to the forum.

These any good?

Bristol Steam Packet boat trips round the harbour and up the River Avon.

The Nova Scotia pub on Spike Island - a traditional watering hole with great beers and ciders.

The Corn Market.

It is a great town for a short break and as you won't be tied down by a car, you will enjoy it all the more.

I've found pub beer mats ideal. And I enjoy collecting them!

Gents, Ladies,

I am not a political person - I despise the lot of them - and yet recognise the harm that they do.

Tonight I have seen this: http://www.telegraph.co.uk/news/2017/05/02/diesel-drivers-will-paid-scrap-cars-improve-air-quality/

And this:

One seems directly to contradict the other.

How does one proceed?

Ah, but there is the absolute delight of hitting the "BUY" button still to come.

Good luck with whatever you decide.

Michael has jogged my memory.

The instructor was Bert Abigail who taught Workshop Practise in Building 66 at Middle Wallop.

The mnemonic was to help us remember the range of GS fixings we could expect to find in general stores.

For some reason I emphasised BA threads - don't know why.

Michael (Gilligan) - Thank you. You have nailed it.
