Wow, Aroy, you can handle bolts and nuts up to 46mm! Did you ever need to? That's huge!

Actually, speaking of huge, I do need a pipe wrench (Stilson type) and a chain wrench that can cope with 2-inch steel pipes and fittings. I knew that post-flood, back in December. It is April, and rains have come again to remind me that I never bought.

Even I was puzzled over the difference between imperial and US, and this doubt was confirmed after I saw a measuring jar. The Litres and UK-oz was ok, but there was another marking for Us-oz slightly different than the British one. The US gallon is also different than imperial gallon.

My dad, once in a factory visit to USA, confirmed that US spanners and imperial ones will get the job done, but there is slight variation in them. He recommends using the system where the machine specification was built. Thankfully except for old machines, most of the ones he works on are metric, so not ambiguity, but once in a while some machine needs a particular US spanner.

Here's a wiki article on the same.

The imperial system has a hundredweight, defined as eight stone or 112 lb (50.80234544 kg), whereas a US hundredweight is 100 lb (45.359237 kg). In both systems, 20 hundredweights make a ton. In the US, the terms long ton (2240 lb, 1016.0469088 kg) and short ton (2000 lb; 907.18474 kg) are used to distinguish them. The term metric ton is also used to denote a tonne (1000 kg, 2204.622 lb), which is about 2% less than the long ton.

Yes I'm aware of volume and weight units, but tool sizes?

[Thad E Ginathom]

Brits use mm these days, but look back in the past, and you can see that they had an assortment of standards. Just see how many "half-inch" spanners there are in this chart

My socket set, which dates back to before UK became metric, has AF and BA sockets as well as mm.

Wot, no Whitworth?

Lots of different threads around. Even Whiteorth comes in variants!

Metric and US sizes are simple - the distance across the bolt flats. British are a bit more complicated as the sizes are for the bolt diameter and not across flats - a few examples from my spanners
3/16 W, 1/4 BS
1/4 W(hitworth) and 5/15 BS
5/16 W, 3/8 BS

A simple example at 11mm there are three sizes needed for the 12 point socket.
Metric - 11mm
US - 11.1mm
British - 11.3mm

The following links have details on history of spanner sizing and tables of various sizes

In most cases there is very little need for British Sizes, except at the smaller sizes.

Where can I find a glass fibre kit in india?
Like this:
http://www.halfords.com/motoring/pai...ibre-kit-small

Or even individual items if something like this is not available?
Or are there some generic indian terms and I am asking/searching for the wrong names?

Yes I bought it to open the Nut holding my motorcycle fork. Once the bike was disposed ~ 1975, I never needed this size, but a few DIY enthusiasts have borrowed it.

My 18" Stillson has graduations from 1/2" to 2", so that may suffice, else you can get a 24"

Mayank, these stuff and may other DIY / Hobby materials are available in India but in bulk, reason there is little hobby use. The resin and hardner can be easily bought from industrial chemical supplier. It's available in 1kg packs. Even smaller would be there. Araldite is a similar epoxy can be substituted for small work. For the Fiber glass unfortunately I have only used the complete roll (comes just like cloth roll). This is also used in waterproofing. So checking with specialised shops may help.

Also check mold & sculpture making suppliers on eBay or Amazon.

Complete roll? Its meshed together? So, you impregnate it with the resin? That ought to work. When you say industrial chemical supplier, do you mean going through places like indiamart, or the neighborhood building material etc guy?? Is there any colloquial term for this stuff? And costs?


Need further inputs in using these M8 hex anchors.
What is the proper way to plant these? What I read was drill a hole longer than the bolt, insert the bolt inside at fully tightened, and then turn it out till tight and till the required length. Is that right?

That is right. Just be sure that
1. The material you are drilling into is firm and does not crumble
2. The hole should be of exact diameter, that is the anchor bolt should be a snug fit

The casing expands when tighten the bold and that is what holds it in. Do not exceed the recommended load of each bolt, as beyond that, it may slip out.

I've got the shopping itch again!

I've got this today, and I've got some other stuff of a similar nature on the way.

Strap Wrench. [Amazon]

More than solves the problem of the 2-inch coupling on my waste/flood-water pump, which would require an enormous pipe wrench or adjustable spanner.

The strap looks like a kind of canvas. It is actually rubberised, so it has some grip. It is described as an oil-filter wrench, but, although it is probably not that strong, it seems much tougher than that suggests. The oil-filter wrench that I have in my toolkit, although of the chain-wrench kind, is quite a flimsy thing: the handle will bend under much pressure!

Yes complete roll all meshed together, and we impregnate with resin. Please indiamart mart sucks, but can give it a try. This stuff is widely used in Industries for waterproofing. So Industrial suppliers should have it. Also mould making material supply guys should have that as well.

By the way mould makers actually use CSM (chopped strand mat) to do the casting. Patch work is usually done with this cloth.

Back in the days FGP was a company making different types / grades of Fiber glass material.

Fiber glass cloth would be right name to ask.

All the ingredients are available at industrial supply shops - FG cloth (matted or woven), resin and hardener.

In Delhi, the likely places are Kashmere Gate, Bhogal, Okhla etc. Do a search on Justdial or Sulekha - you will find plenty of dealers.

More than solves the problem of the 2-inch coupling on my waste/flood-water pump, which would require an enormous pipe wrench or adjustable spanner.

The strap wrench absolutely does the job, and it would have been fine if I had stopped right there, but, I had the itch, I was in buying mood, and there's no stopping a shopaholic in a toolshop. (and the internet is one hell of a big toolshop!)

Inspired by some video I'd seen whilst searching out info on strap and chain wrenches,

I bought this...

Boa Constrictor Wrench Set of Two (Amazon UK)

and, just to be certain I'll always be able to turn a round (or not) thing...

Huge Boa Constrictor with Aluminium Handle (Amazon UK)

I got them today, which is not bad for all-the-way-from-UK, with no customs delay, charge or hassle.

It turns out that even the baby boa would just-about handle my pipe fittings, and that the standard (red) boa now comes with the same length strap as the Aluminium model. But hey, suppose I want to hold one large thing while turning something attached to it? One can never have too many tools

Or so I'm telling myself!
