I need some basic dimension for Vicmarc chucks. I don't seem to find these from the web searches I've made.
Please, what (Vicmarc) chuck do you have?
What is the diameter of the chuck body, please?
What is the distance from the spindle shoulder to the jaw side of the chuck body, please? We're working from a base assumption of a 1-1/4X8 spindle so please include any adapters.
This is for a student project.
Thank you for your help.
Vicmarc 120
dia 125mm
depth 100mm
vicmarc 100
dia 96mm
depth 78.35mm
depth is with adapter
My 120 is 4.92" / 125mm in diameter and measuring from the back of the adapter (1 1/4x8) to the face of the chuck without jaws attached is 3.13"/ 79.62mm. My chuck came from Craft Supply so the adapter may or may not be made by VicMarc (didn't ask).

Dwight,
Thank you
Alex,
Thank you

I didn't see dimensions for the inserts once threaded into the chuck using the length. The students need the depth of the mounted chuck body against the spindle shoulder.
Thank you
My VM100 chuck with my 1¼" x 8 TPI adapter is 69.1mm to the face of the chuck. Bear in mind, that the jaw holders are proud of the chuck face.
My VM100 chuck with my M30 x 3.5 adapter, is 69.3mm, so there seems to be either a plus minus factor, or my measuring technique is not the best. I placed my chuck with adapter on my bench and used my 45 year old Mitutoyo vernier in depth measuring mode.
Both of those adapters are Vicmarc supplied.
The nominal distance is probably 69mm.
The diameter of my VM100 is 96.1mm on the actual body. The diameter measured on the scroll key points is 97.3mm
My VM120 chuck does not need an adapter, it is a direct screw in job so I cannot help you there.
Mick.
thanks, Mick.
