Yes, centrifugal separators are nothing new, devil is the details.
So it would be great (OT for this thread, so maybe a new thread on aircleaners in the technical section) on different designs, with their pros and cons? And why.

Was in Mumbai on Saturday and had time to visit Crawford Market area.

While searching for Stanley shop in that area, I discovered a 'Stanley exclusive' shop - perhaps a distributor near Nagdevi Street.

Purchased several tools with 30-40% discount.
One of them was this one and it cost me around Rs. 1350 (MRP was around 2200).

All those streets are filled with hardware and tools shops. It is a bit over-whelming to see the size of the market on your first visit. :)

Amen! I just needed one bit to put holes on the Alu. angle bracket to route the clothes line and to fix them on the wall.

This wasn’t a precision hole so just the hole and some filing to get rid of the sharp edges worked well. :)

Safety glasses are always on when drilling holes on the wall (fine dust!) so this wasn’t any different. Gloves - not sure. Haven’t done any hard core machining work at home so never used them. Will order a pair for safety sakes.

Got an HSS drill from the local hardware shop for Rs. 30. Set the drill at a low rpm (500’ish I think) and it drilled through the 4thk Alu. angle like a hot knife through butter! Absolutely smooth. I didn’t have a cutting fluid readily available (where do we get kerosene nowadays? Ration shop?) so skipped that. The angle was barely warm after the job.

I held it with a piece of duct tape on 40 thk wooden board:



Very bad I know but I didn’t have a choice at that time. Neither did I want my wife to hold the angle for me since she has never held a tool with her hand before. Next thing on the to-buy list - couple of C clamps. I missed them during this job.

Yep. Used a punch and hammer to locate the hole on the piece and then drilled through it.

Thank you for the responses guys. Appreciate it.

Thanks! Good idea. OTOH isn't there a vacuum cleaners thread somewhere?

Grinding Aluminium?
Positional accuracy of hole centre?

Somehow I thought you were embarking on a much bigger job!

Searching for Dyson here does not throw up anything relevant.

Not synonymous in India, no?

Here is photo of the recent purchase.

Here is an offer on Dremel for Bosch employees. Posting here so that if anyone in need can get it through their friends/ acquaintances working there.



Please note that to avail the EMI facility, the person buying should be a member in the society run by the employees.

Please call Mr. Rajkumar in case you wish to talk. He is the owner of the DIY square where this product is being sold. The other gentleman is from the Bosch and may not take up outside orders.

Mods please note that I have no interest in the above and posting for the benefit of fellow bhpians. You are free to delete this, if found otherwise.

Quoting this post since this is the only mention of toledo in this thread.

Buyers just be aware. These guys are a bunch of incompetent buggers. Avoid dealing with them. I've had some issues with them and on searching the net found a host of complaints against them.

I had the same dilemma and luckily didnt use them to buy any items.

Hope this query satisfies this thread.

We have bunch of RC cars, the toy ones. Some RC joystick are broken and nowhere to be found. Does the available joystick be used to control any RC cars. I just see 27Mhz sticker on available cars and RC, but not sure whether it can be worked.

In some RC cars, the channel is selectable (this changes the frequency a bit, e.g. 27.35MHz or 27.82MHz). If it is, then another similar remote (with selectable channels) can be set to the same channel to control it. The alternative is to change the crystal used in the car to make it suitable for another remote.

Open one of the RC cars (whose remote is broken) and check if it has a switch mechanism to set channel. If not, you have to keep trying with the other remotes to see which one is suitable.

As of now none of the remotes work. I will open some and see both. What is that crystal change thing? Could you elaborate?

'Crystal' refers to the quartz crystal oscillator that sets the base frequency of the transmitter / receiver pair. The transmitter encodes the position of the speed or steering control and sends it to the receiver, which uses the value to set the speed and direction of the main and steering motors. Both the transmitter and the receiver must have the same crystal frequency for the pair to work together properly.

The crystal should look like one of these (pics from internet):

I am unable to find any thing of this sort in the car internals. And there is no option to change the frequency too. Is there a universal remote or anything which can come to my rescue?

I doubt any manufacturer will have support for universal remote. Business considerations aside, imagine the catasrophy of a moron taking control of your RC vehicle using his universal remote.
