Just a small question, what should be the price of Stanley spanner with ratchet on one end and a open C on the other side? I got 2-3 of various dimensions for around Rs. 350-450 each. The quality is top notch and definitely been put to use many times (by my dad mostly when he works on machines with tight spaces ). But similarly priced local/Chinese were dirt cheap but looked flimsy.

My father, with his long time working with printing press/binders/book trimmers etc has amassed quite a nice collection. The star of those are a bunch of Swiss tools in their leather pouch that I'm not allowed to use. :P

That's quite a lot. If it is aluminium, then it would be like cutting butter, but steel, even of that thickness would take some elbow grease.

If you decide to file, then go out and buy the right files. I suggest that you use half-round rather than round (round is called rat-tail, I think) and you need a course-cut file to remove most of the metal before finishing with a finer cut. The half-round has a much bigger diameter which will suit your hole shape better than the small rat-tail.

It is a long, long time since I bought such tools, but I think that the coursest-cut files are called "*******" ()*, and then there is first-cut and second cut. Single-cut and double-cut refers to whether the teeth are made by one or two sets of diagonal lines on the surface. This is the language of files, but I may have forgotten, and look forward to correction.

Please remember that a file cuts on the push stroke. Do not apply pressure when pulling the file back, as it only blunts the file. Even professionals are often lazy about this, even though, if you ask them, they know!

But a grind or cut tool on a dremel is cetainly going to be the labour-saving device here!

The usual compulsory warning applies...

do not forget to use eye, or even full-face, protection. never do any grinding work without it.

Not even for one minute. Just one speck can blind a person, and entire grinding tools can break up.



*haha, the system edits it. b---ard, literal meaning, outside of engineering, an illegitimate child, but generally used as a term of abuse. Within engineering, it is a kind of file. Or the boss

Draw the larger circle on it. Put it on something flat with a hole in it and use a round metal file to increase the diameter. Its only sheet metal, will go very easily.
Good luck.

Thanks a lot for the suggestions. Looks like filing is the way to go. Its going to be tedious.

BTW, while googling, I came across step bit/pagoda bit. Anyone tried this? Seems a bit expensive though. Not sure if it is available in local stores. Need to check it out.

With enough protection, I would have tried a drill with a grinding cone.

That's a good idea.using a die grinder bit in a drill.it should work.just the rpms will be low but its better than doing it by hand.

[Thad E Ginathom]

Yes, that sounds like the best idea so far. You may need a half-round file for finishing.

For practicality and safety, make sure that the panel is very firmly secured in a vice or clamp, and cannot rotate if you are using a power tool and it snags. Also, when filing by hand even, without good support/grip, a lot of your energy gets wasted just making the metal vibrate, which is very frustrating.

Even I think that a conical grinder bit will be the best bet.

So got a new set of trim removal tools.

My earlier set only had the two plastic parts- the spatula and the forked crowbar type of tools.

Can anyone help me with the names and indications of the other tools? Have numbered them for ease.

Thanks in anticipation.

[Thad E Ginathom]

Well, I suggest names like spidger, sprangler, and whatsit.

And I suspect that I'm probably not far off!

[Aroy]

Bough a few tools in the past two months, got excellent deals on the net


Combination spanners


Screw Drivers. I had bough similar sizes about 45 years ago, but storage with some chemicals ruined the handles - they just disintegrated over the years


Circlip pliers

Hi,

Where will we get crimp terminals like this on SP Road Bangalore.



Any pointers regarding shop and price would help.

Firstly, I am not a DIYer. But thought of posting my query here to understand if what I am trying to achieve is actually achievable and how.

I recently bought a stainless steel kitchen sink of 1 mm thickness (link: http://www.futurasink.com/index.php?...&product_id=88). I also want to fit a filter faucet (the one for under the sink water purifier) beside the normal faucet and hence, have to drill a half inch hole in the sink.

My questions are:
1. Who can do the job? Can it be done by person who do iron works (grills, gates, etc.)? Or do I need to take it somewhere else (lathe shop, etc.)?
2. What kind of drill bit is necessary to drill this hole?

Thanks in advance.

Take it to a machine shop. Grille people won't have the necessary skill and equipment. Ideally you would need slow speed lubricant cooled drilling with a cobalt drill bit.
