Seeking someone to make a component (spacer)

That's like leaving your nails in seawater for a month, so they don't rust…

well make them for him or shut up, simples

I offered to do that at 10.30 this morning but the OP hasn't worked out that there is a messaging system on this forum because, despite being logged in, he has not yet read it.

Oh, just now seen my inbox. Forgot about that. Will action after I've voted.

[Richard RogalewskiParticipant @richardrogalewski21509]

One point. These spacers are normally porcelain. I assumed that a product I can buy (but not suitable – shape wise) was nylon. But it's probably porcelain or ceramic. I suppose I'm okay with nylon. I know there is a meter board specification. Don't know if there is a spacer specification for meter boards. Quite obscure specification.

Certainly, I belive the spacers were meant to prevent damp affecting the meter board.

"Nylon absorbing moisture" – Really? It is that Mission Critical we are even going to consider this? Give me a break. It isn't worth considering and if we are going to consider electrocution, again, really? We have an earth I take it?

Thanks Graham – I read the original request, saw porcelain and electric and thought automatically it must be insulating for some reason, perhaps high voltage.

I also use Direct Plastics and would recommend them, and off topic, I've bookmarked these **LINK** for a potential order of some 3 to 5 mm steel plate for a project.

Here's the deal £10 each that takes into account the cost of my time plus cost of machines and tooling ,why have a workshop just get someone to do the work for you. A few plastic or fibre washers will do this little job .

[Richard RogalewskiParticipant @richardrogalewski21509]

I should have stated PVC then, rather than nylon. Don't know why I assumed nylon. Actually, practically, the main requirement is that the spacer looks a bit like porcelain in appearance. Trying to get a sort of visual match with the meter board spacers.

Just going to see what PVC round bar is on sale.  To get an understanding of what's available.

Didn't one of the Sieg lathes offered by Arc have a larger than standard bore?

If you want it to look like porc then maybe white corian would be a better bet, polishes up to a reasonable shine.

[Richard RogalewskiParticipant @richardrogalewski21509]

Just to keep people informed: I contacted the first chap who offered to make the spacers. I'll probably end up sending him the required round bar. Corian as a material – noted.

"That's like leaving your nails in seawater for a month, so they don't rust.2

Another silly analogy .. Ffor moulded nylon parts to reach their optimum physical properties they need to be immersed on water – often boiling water to "normalise" them. This is standard practice in the plastic moulding industry See **LINK**

[VicParticipant @vic]

If PVC is the reccomended stuff use that, it's cheap enough.

[Bunny CrabbParticipant @bunnycrabb20762]

I would pass on the same suggestion that was made to me. It was to contact someone with a 3-D printer that could print your spacers so they look original and even use an off white so they look aged, or buy one to use. I bought one new for $265 US dollars, as it was cheaper to buy than make for me with the price of my time spent.I have been printing items on a daily basis. I added a 3-D scanner to it mold or carve the part the duplicate it as many times as needed. I am currently booked up for the next 19 weeks. I would offer my services to you, if you couldn't solve it yourself, but I am overloaded machining and casting or printing parts. It is a money maker and If you want plans I have some for a 3d printer. working in this craft, it would be simple to accomplish.

That's what I like;
wake up in the morning, and before I've finished my first coffee I've learned something new 😀

I looked at the spec for various different plastics for a particular project years ago and found that most of them absorb water to some degree.

Needing slippy stuff I went with Ertalyte TX in the end.

[paul 1950Participant @paul1950]

save me lighting up my forge anyone want to make me a bench hold fast, i will give you a couple quid!

[Brian WoodParticipant @brianwood45127]

All this talk of water absorbtion is really just plain nonsense, my board is timber sheet, possibly plywood, mounted flat on the external wall and screwed to it with wood screws through porcelain collars under the screw heads, looking very much like those drawn by the OP.

There is no apparent protection at all such as a moisture barrier to the timber sheet, the collars are there purely as insulators to isolate the board from the screws. Clearly a damp board, which mine isn't, doesn't matter at all !!
