The design of this spindle will probably be longer that the design on other ones, so mine may well be a special.
:dejection:Back to the trawling then....:sorrow::sorrow::sorrow: HELLLLPPPP Im going round in circles here...lol
no reason why we can't keep going down this line, it just means my ones will be slightly different
im sure we will get there, as i said i can wait for the best solution anyhow..Quote:

Did you get anywhere with this?Quote:

'Fast delivery and nice spindle, but not the dimensions shown on the drawing on the listing. Diameter is 80mm above the flange and 85mm below it. It is in fact a SIPU model SPP8030-060-10F But still a BT30 ATC and 6000rpm so I am happy. :) FYI the timing pulley is a 45 tooth HTD5M and is 35mm wide Thanks'
Still too much to spend for me to only get 6000rpm...
got the spindles back from the grinder and a bt30 hoder rings quite well into them. I'm in two minds now whether to leave the motor/pulley arrangement as is (bridgeport), or remove the pulley section and mount the motor directly on top of the spindle with a drawbar through the motor.
Well I got there in the end but via a different route. I ended up buying two HSD router spindles which have a 30 taper and air powered atc. They are 6.8kw and 24000 rpm, and should have a fair bit of power run at slower speeds.
Both of these I presume?
