These are just drilled blocks of wood so still suffer from being ugly as hell out of scale and tend to snag the lines just at the wrong time. Only to release them again when you think it's all done

While there look out for me and "Nannie" and her tail....😜👍

They don't have to work but from rigging a 1/350 scale Cutty Sark. I realise that they still do the same job and as such all have to be adjusted until everything's just right. While this is possible with plastic or solid wood blocks there is a tendency for the lines to snag on the uneven surface. So creating tight spots which suddenly slip meaning all the other lines are out of whack. And the plastic blocks tend to snap at the becket causing even more headaches. So apart from the greater authenticity, it's a big help rigging the standing lines.

Also last time I tried working with pignut vitea I spent more time sharpening the tools than working with them as its nearly like planning steel. And that's what was in the original blocks so no thanks.

The only problem is inside the wooden blocks needs round wheels. And at this size wood just crumbles it's all about scale. While accuracy would be great I can't make wood molecules any smaller. So I've got to choose another product. Enter the next thing they used brass. And as its self lubricating if it's cheap enough because of the lead content which because of the structure of brass sits on the surface so giving it that smoot slimy feel. Wait that's an engineering fact. Oh my word your rubbing of on me quick pass me a lump of wood and perhaps it'll wear off...

Sounds worth a try thanks.

Thanks for that. Not too sure about the first as it sounds way too safe . But the third is doable even if I used wooden dowel on marbles to create the bearings. And I'll definitely look into the third as its a route I haven't realised existed. That's why I'm here if in doubt ask the best. And I'm the biggest doubt...

Too late on the sanity side I'm glad. But my engineering contacts stop at the number zero so looney tunes here I come sorry already am :-P

Hi folks,

Not only is it that time again but it's double as its bank holiday. So for those who don't know me don't worry you'll soon recover. For those who do. When you've stopped groaning. IM BACK...

Right down to business. I've got some basic brass tube 2mm OD and 0.3mm wall thickness. Now please remember apart from a lot of sharp knives and a junior hacksaw. I'm a wood top so have less than nothing in the line of engineering skills.

What I need to do is repeatedly, about 700 times, cut slices of said tube 0.5-1mm long. Now I know I can cut said tube with a sharp knife. So it's not too hard it's the accuracy I'm struggling with and I'm sure there is a safer way than a big swing with a meat cleaver. especially when I'm holding the tube. I still want to be able to count to ten without rummaging around in the sawdust.

So how can I cut this tube please?

In case your wondering what I'm up to now. I've given up on the distilling. It was all just hot air. And I'm now all at sea. I'm trying to make some pulley blocks. Enough to to rig the HMS Victory and about 8 other ships including three Cutty Sarks. And as the Victory requires around 700. Never mind the rest. I'd like a nice simple way of making them. Emphasis on SIMPLE please.

Hope you are all well since my last visit no lost limbs or nervous breakdowns. That's my job, to give them and have them...

" But as soon as you add ice and lemon... BIG no no."

If you wish to make your self a methanol suicide cocktail be my guest. And as sloe gin is made by adding sloe berrys to ready made gin. Also even if a mate came around to mine for a drink, if that was what I was making, as soon as the ice hit the glass of ethanol its big fines and probably prison time without a distillers licence. And plant approval.

Most modern engines since about 2008 ish have been built to run on either ethanol or petrol without the need for alterations it is also used in bio-diesel to boost the energy output.

Sadly even at 40% ABV it's very illegal to so much as taste it. Even if it's for your own consumption. So long as it's for a provable use such as powering a vehicle 95%. But that has duty on it and has to be under 2500 litres per year. Or bio-ethanol 99%. For home heating still under 2500 litres per year. And no waste handling problems. It's leagal. But as soon as you add ice and lemon... BIG no no.

Hi,

I've no intention of breaking any laws. As I said I've checked out through HRMC and as far as I've been informed by the government I'm not actually creating anything alcoholic or changing anything. Just turning it from a saturated liquid. Into steam and back into an unsaturated liquid and back again. I'm not rectifying the ethanol just sepperating it from the dissoosolids which are what I'm after. But thanks for the link I'll check it out and act appropriately to stay within the law.

A very valid point which I endorce and take on board. While my approach to getting answers to my question were flippant all seriousness is undertaken.

Thanks Neil

That's one of the reasons I chose that size as all the sites mentioned normal fittings. Just not the o ring bit. Thanks as that makes lots of sense as there is no pressure other than the volume of water because the top of the pipe is vented. Also there's a place on eBay does any size glass for just under £5 including P&P and cutting off a 15mm OD x 300mm glass tube. So I should be ok, perhaps loosen the opening a little with a dremell type sander. If there the same size. As Im also thinking different materials different expansion rates. 

Thanks

First of all I ac do have a chemist advising. Second acrylic should only be affected by acetone based solvent which wouldn't even need heating. Thirdly distilleries have been doing the very same thing for several hundred years. Fourthly so long as any production produces no was problems, is for specific use such as heating, and is under 2500 litre a year, and never leaves the premises, then it's fully leagal. According to HMRC. You don't even need a licence to distill vehicle grade fule. But I'm actually recapturing used ethanol that has a dissolved solid in it then I can reuse the same solvent again and again..

But thanks for the concern.

I've been looking all over but I'm struggling to find actual plans just people on forums talking about it. I'm probably not using the right search criteria. Could you suggest a particular link please

Thanks Chris

I had similar concerns over the melting, but keep reading on different websites how people have used acrylic in models.

My only issue now is how do I attach it?

Any polite suggestions gratefully received.

Hi,

Another weekend, another daft question.

I'm wanting to put a sight glass on a small open flame heated. Small spirit lamp. The bottom of the "boiler" is flat and about 300mm diameter. The glass would probably be another 50mm further out from the side. The internal temp shouldn't get higher than 100c, probably not that. As there will be volatile fluids in there. Ethanol to be precise. Which boils at 70c ish, also it a low to no pressure system. Just trying to boil of the unwanted fluids from the wanted, and be able to collect the condensed evaporated liquids. If you know what I mean. Purely for the purpose of refining certain liquids. That would never come in contact with a glass of tonic water and some ice.

So here goes. And please be aware I'm just a thick wooden top. So simple is best.

Glass is nice doesn't stain and can cope with none direct heat. But Perspex is cheaper.

Can I get away with 15mm OD Perspex pipe?

How do I stop it deforming?

If so how? And how do I attach plastic pipe to copper/brass fittings?

And finally. If I've got to go with glass. Same question. How on earth do you get a water tight seal with glass on brass/copper?

So picture are very helpful as are names of parts and possible suppliers

So why do new toolboxes have mirrors then. And are you just saying in a round about way people with diagonally placed mirrors in their toolbox are big heads...

Any try typing wooden toolbox with drawers then you'll see more
