ANOTHER PM-833T UPGRADE

[RIMSPOKE]

ASIAN TABLE MILLS USUALLY HAVE A THREE ARM QUILL LEVER .

I GUESS THE THINKING IS THERE WILL ALWAYS BE ONE NEARBY WHEN YOU NEED IT .
TROUBLE IS , THE OTHER TWO OFTEN GET IN THE WAY !

THIS LEFT ME LONGING FOR A SINGLE INDEXABLE ARM AND I MADE ONE FOR THE 833 .

THE PARTS ARE MOSTLY MADE FROM STAINLESS .
IT IS QUICK , STRONG AND OPERATES SMOOTHLY WITH ONE HAND .

MY DESIGN USES TWO LEVERS . A LONG MAIN ONE FOR PULLING DOWN ON THE QUILL
AND A SMALLER SHORT ONE TO DISENGAGE THE ASSEMBLY
FOR INDEXING .

IT WORKS WITH A SLOTTED RING THAT PROTRUDES INTO THE TURNING MAIN BODY .
A SPRING LOADED TRIGGER ATTACHED TO THE SMALL LEVER PULLS A 3/16" DOWELL PIN
OUT OF THE SLOTS AND SNAPS IT BACK INTO THE DESIRED POSITION .

I WILL PROBABLY HANG THE THREE ARM BANDIT ON THE WALL
IN CASE I EVER HAVE A USE FOR IT AGAIN .

Very nice work and very inventive. It seems like we were on the same path, just headed in opposite directions:

New Quill Feed Handle for PM935

Using my new PM935, and coming from a Rong Fu 45 (the real one, not a clone), it seemed to me that every time I reached for the single quill feed handle, it was indexed to the wrong position. So I decided to make a new 3-spoke handle out of stainless. The quill feed handle interface to the...

Impressive work as usual, very well done and clean approach. I use a single handle engagement lever on my knee, works similar except the handle is spring loaded so you can quickly chance the position with the same lever. It uses two rods which lock in a series of holes when the arm lateral movement is released. The 833T is one sweet mill, that you have done some very nice mods too.
