26A Red Wing Lathe Instruction
CHUCK REMOVAL INSTRUCTIONS
Remove the lathe from the carton and place it in a suitable location on a sturdy horizontal surface.
The unit must be bolted to the table top. Bolting the unit securely to a solid table top will prevent
possible lathe movement during operation and possible operator injury.
Plug the lathe’s cord set into a grounded 115 Volt/60 Hz electrical socket only. Do not utilize a
3-2 prong adapter. Failure to plug the lathe into a properly grounded receptacle may result in
operator injury. Your lathe is now ready for operation with the aid of chucks placed on the shaft (see
instructions).
The No. 26, 26A, 26L, and 28H lathes are constructed to function on two speeds. Low speed is
1725 RPM and high speed is 3450 RPM. The lathe shaft is provided with special dental tapered
shafts which will accept chucks which fit onto a tapered shaft only. The models 27, 29, & 29A are
built to function at 3450 RPM. NOTE: if you have specified that your lathe should contain 1/2” straight
shafts, only chucks which contain a 1/2” arbor hole will adapt to these shafts.
The polishing motor with a tapered shaft is provided with a left and right chuck remover (see figure
No. 1). By pulling upward toward the front of the lathe, the chuck remover will unscrew outward to
“push” the chuck from the tapered shaft. Various types of chucks and chuck accessories are utilized to
perform different types of grinding and polishing operations with your lathe. These are attached to your
lathe’s shaft via a friction fit.
TO PLACE A CHUCk ONTO THE SHAFT OF YOUR LATHE, PLEASE FOLLOW THESE INSTRUCTIONS:
1. Make certain both the lathe’s shaft and the arbor hole of the chuck to be placed onto the shaft are
clean of any dust and debris. Be certain the chuck remover on each side is in place.
2. With the lathe turned “OFF”, place the chuck onto the right or left shaft of your lathe. DO NOT
place a chuck labeled “R” or “L” on the opposite shaft. (See Instructions on following page.)
3. Push the chuck onto the shaft as far as it will go. Since the chucks fit onto tapered shafts via
friction fit, make certain the chuck is placed securely on the lathe shaft. It may be necessary to
tap the end of the chuck onto the lathe shaft with the aid of a soft rubber, plastic or leather
mallet. Do not use a metal hammer or mallet as this will damage the chuck.
4. After the chuck has been placed securely on the lathe shaft, place the buff, brush, abrasive
wheel, bur or mandrel onto the chuck. Secure this in place as per the manufacturers suggestions.
5. Turn the lathe on and make certain the accessory which has been placed on the lathe chuck is
securely in position. If either the chuck or accessory have not been secured to the lathe shaft,
secure it now.
NOTE: Many Red Wing polishing motors are shipped with 1/2” straight shafts. Chucks used on Red
Wing Polishing motors equipped with a 1/2” straight shaft utilize a set screw to hold the chuck in
position. Make certain to tighten this securely.
