Chester used 1 1/2 pony motors on these for years, current spec 1hp same as my Zay 7045 bought from Chester in 2004 new £930 when they were £1500.
Warco uses 2hp spindle motor.
Used to keep looking at the 626 but such a short X axis travel around 14". Don't look at parts up to 14" long the cutters ideally need to clear so your 2 1/2" cutter will take 5" of max length obtainable bringing it more like 9". Lux without power feed will get 23 3/4" X axis travel, with power feed 21 1/2".
Far quicker and easier to change speeds on Lux's, 626 have to faff about with belts.
626 have to compare with the Lux not Super Lux which has power head elevation, my gearbox packed up 7 yrs ago and not prepared to pay £240 when whole machine cost £930.
Limiting factor on Lux's is the slow spindle speed, doable but takes an eternity having to slow feeds down.
The head is real heavy full of gears and oil.
Second Clives findings buy a decent torch or send X axis 11" down, I do it regular.
May need that height of the Lux's with normal tooling, regularly run within 1 1/2" of maxing out on height with a low vice.
If have the option choose R8, though MT3 never been a problem – ever with finger collets.
Have the Bridgy style power feed on as well on the right, meant for the job ones will interfere with some jobs and on wrong side to see dro.
Have had the Super Lux since June 2004 used daily for small scale production mainly aluminiums. A Bridgeport I could do jobs 3 to 4 times quicker and leave a better finish and have to go that route if I can spare two months downtime.
Have a mate who has two Lux's, a 626 and Model T Super. He has had a Bridgeport, his words will cut with blunt cutters and is more robust but virtually no other gain over the Lux's.
Wouldn't say its about looking after the tools its about using them whether or when the will break or wear out, all imports will.
