Chinese Spindles

Unrelated i Know but look at what ive got... another toy (this was the picture from the auction)

Have you still got my mobile number, i have an idea for a cheap and sturdy router

I've had a thought. We discounted making these spindles as it would be too much hassle making a one off. But i want two, and overall we're looking at five so maybe we can get this sorted and get 5 universal bt30 spindle sections made, and configure the case and bearings to suit our own requirements. This way we all get what we want and the expensive ground spindle can be made for us.

Well I'm willing to explore that avenue, whatever gets me the ATC spindle i require..

I'm all for that, but things like this gentlemen's experience worry me:

The other problem is the cost of the super-precision bearings which are a necessity for the sorts of speeds we're after. The place I posted in post #101 may help there.

I bought plenty of 35mm EN19 steel for precisely this project...

As i stated earlier in the thread i want as much flexability as possible which meant buying a seperate motor, 9k is to high for the lower limit.

9k is almost certainly not the lower limit, I bet it is 9k upper limit with 'standard' bearings and 12k upper limit with the better ones.
I was going by what you said here with regards to including a motor:

I bet once you pass 10k the price goes up as much as the rpm..... lol but it would be nice if it had a motor on from where i sit, as i will have to buy one anyhow and im sure that wont be cheap.

But if you're prepared to do the extra work to attach your own motor then that is definitely the best solution since, as you said, you require useful power at 1000rpm.

anybody else want to jump on

i'm going to have 2 pole 1.5hp 3 phase motors on mine, and i fancy drilling through the motor spindle and attaching the atc actuator on the top of the motor so everything is in line

I will have to stick with pulleys

well i've spent a few hours today pulling apart the J head on the first quatro, and it looks like i'll probably be stripping the quill and putting a new bt30 atc spindle into it to replace the R8 spindle. It would be a shame not to utilise the existing head and quill with it's bearings.
The design of this spindle will probably be longer that the design on other ones, so mine may well be a special.

Back to the trawling then.... HELLLLPPPP Im going round in circles here...lol
