Joe you differently have a flair with your equipment, Nicely done, Please give us all the details on how it works out for you. C.A.G.
----- Original Message ----- ok, some negatives and positives...the unit takes away 14" from my length between centers...but in my case, that is not a problem...but it can be removed in less than 5 minutes to get back the 14", should i ever need it on a very long piece...thus the reason i wanted something im place that would stay set up, ready to use...to do spiral work, simply turn the hex nut pictured at the top of the motor base and the belt will loosen, thus not turning the motor pulley and putting unnecessary strain on the gear train...to use the motor spindle, simply loosen the screws on the shaft collars, slide the collars out of the way, and remove the 1" rod connecting the two headstocks...you are now ready for the higher speed spindle work...the entire assembly moves with the legacy bed in regards to going up or down and it was worked out so that a maximum turning diameter of 11+" can still be achieved...if i should ever need more in regards to the diameter, i can modify the wood base a bit to allow the motor more downward adjustment...still need to mount the DC controller, probably on the z-axis carriage, but did a quick-hook-up test and all is good...the legacy headstock is not bolted or welded to the motor set up, so it locks to the rails with the legacy hardware, as originally intended...will also be making a cover for the pulley projecting up out of the headstock cross bar...will continue this description as things come to me...joe On Monday, June 30, 2014 4:01:00 PM UTC-4, joe biunno wrote: ok, start from the beginning...thought turning a workpiece faster than the legacy would normally allow, would have benefits doing certain jobs...and after a group search, seems a good amount feel the same...so i set out to do this mod...but also wanted to do it on the cheap so i remembered i had picked up a never used/new, baldor, 1/2 hp, 1725 rpm, 90 volt DC motor...now before anyone starts saying that this is overkill for what it is expected to do, i will agree that it is a bit more than what is needed...but it is also a $500.00-plus motor that i picked up years ago for $10!...so i was determined to use it...and perhaps that extra torque could come in handy one day...i also wanted the set up to be on the machine at all times, with little to no machine-mod time to to use it, not interfere with using the gears when necessary, not increase the foot print of the legacy itself, etc., etc...so i decided to incorporate the second head stock i had...and before mac chimes in, the only work done to that headstock was the slot cut into the top...otherwise no drilling, welding, etc. done to the headstock...so it still can be used as intended, if necessary...i also decided that there was no way i was going to spin anything 1725 rpm on the legacy, so i decided to use a 6" pulley on the headstock spindle and a 2" pulley on the motor...this knocked thing down a bit to 575 RPM...a DC controller gotten on ebay will take over from there to give me a nice range from 0 to 575 and if i ever get stupid enough to try it, i can play with the pulleys to increase the speed...but this set up will give me plenty of torque, if i should ever need it...the motor is mounted on an adjustable motor base that was modified a bit to shrink it's height down...this was just some cut-and weld work, no big deal...the motor base is welded to the two cross bars that can slide on the legacy rails, and the unit is locked down with legacy inserts that slide into the rails and some allen head bolts...it can come off easily by simply removing the four bolts and sliding the belt off the motor pulley...will continue this mod in a reply message -- You received this message because you are subscribed to the Google Groups "Legacy Ornamental Mills" group.
