The 2.2Kw Chinese Spindles - Info, Setup and Advice + More

[paulus.v]

Now the uk shipping spindle prices are lower than the Chinese ones (solar.jean). Is it possible that the quality of the spindles sold by solar.jean is better than the new batch of the Portsmouth ones?

I need to buy the spindle and am confused now.

The spindles from Portsmouth are the 3 pin type, I don't know if that means anything.I have to say delivery was fast and it was well packaged,I paid £218.00 from lovehappyshopping.

I received mine a few weeks ago from industry-village and it has a silver end cap where the connector goes and its got 4 pins.

Some have 3 some have 4 but only 3 of the 4 pins are used the 4th pin is unconnected to anything. Some use it for an earth.!

I have been running my spindle on and off all day, got it connected to the garden tap and outlet into the kitchen sink,. problem is I keep getting air bubbles, I used PTFE tape but got loads of air then I noticed a leak at the tap so sorted that but I'm still getting tiny bubbles, hope the spindle isn't porous, it has had water running through it most of the day so I would of thought it would of tripped the RCD if it had a internal leak but it hasn't. any ideas. Thanks

Don't worry about it will be fine so long as water is going thru it.

I use a cheap 12V water pump as sold for use in caravans. I start it on 12V and always get some bubbles coming out of the spindle - useful to see that the flow has started! Then I switch to 5V for normal running. You don't need very high flow rates, at least not for modest cuts.

You won't need much coolant I have a small pump a radiator and 12 metres of pipe work. In all it runs on just over half a litre....even after 2 hours of running the water temp is only 18c. After the install i had small bubbles for 1 hour max since then i have had no bubbles or lost fluid in 7 months. You will be fine. I bet most if not all of your bubbles are coming from the mains tap water. When you do get it all sorted out use pc cooling fluid as tap water in parts of our country can be very hard. You don't want your spindle to scale up. Maybe the water is soft where you are. Cheers Andrew

In my Belden wire it has 3 insulated cores, an. Outer foil shield and a non insulated wire together with the shield. So are you saying connect the shield and non insulated wire to the spindle body at one end and to ground at the vfd end?
