Finally managed to find some compressors for < 10k. |
Check with any compressor rent outs (painters or paint shops will help you in finding one). They will have different types of compressors, heard a new one (not professional grade) costs around 4-5K desi ones
I have never bought a compressor, but I'd be wary of buying unbranded as safety may be an issue.

Usually safety is not an issue even with the unbranded ones. The motor drives the air compressor via v-belt, and there is steel mesh protection around the motor-compressor assembly. Electrically, using an MCB on the line feeding the motor is a good policy.
How about the pressure tank? Or are the pressures not high enough to merit worry?
Finally got Woodpecker 25l direct drive compressor for 8.5k. Went for this model as they had a local dealer and provided a 1 year warranty. Besides this I have ordered an 18 Guage brad nailer from Tolexo (brand Wudtul). Here are some pics of the compressor.
Thanks,
Venki
Guys need help to figure out how to fix a circuit that is draining batteries. I purchased a weighing scale from the US and it drains the battery in a couple of days. Any battery that I put in - Duracell too. That's really expensive to maintain and I would like to see if I can check if there is a short in the internal pcb. Has anyone done this before? I have the same issue with a motion sensor spot light that runs on batteries. Would like to fix both if possible!

Connect a DMM in ammeter mode between the positive pole of the battery and the socket on the device, connect negative in a normal fashion or via a piece of wire. you should see a positive value when the device is on, check if the DMM picks up any reading when device is off - that tells you if there is any leakage.
Hmmm not exactly under the tools heading, but I am looking for some pulleys of three to four inch diameter. Where can I pick them up?
Also on the tools front, I bought a cordless Dremel from Flipkart a few months back. Have found it useful for odd jobs like shaving the sharp corners of cabinet doors and drawers.

As SunnyBoi says you can hook up a DMM in less than 1 A range to check for current consumption which is the easy part. The hard part comes when you need to figure out which part consumes the current. Normal quiescent current ( when the equipment is not doing any work) should be less than a mA. If it takes more or stays put in the work mode where it can consume a few mA, you need to isolate the component. Usually for such gadgets, it is COB type where most of the electronics is etched into a small blob of silicon with very few peripheral components.
But if you do spot an electrolytic capacitor, chances are it could be the culprit.
If it is the COB, it may well end up in the dustbin.

What sort of belt type and size are you looking at? And what is the OD of the shaft where the pulley sits. Here in MIDC Pune a shop by name Divil Engineering specialize on gears. I guess you can find their contact in Indiamart or so.
Virtually getting a pulley turned out from a lathe is possible and not as difficult as getting a sprocket made.
Oh, I needed them for a household project. Found them in a local hardware shop. They are small and not very strong but fit my purpose.
