Hi guys,
18 months ago I bought the 70mm Viper 2 chuck and several sets of jaws for it. I have had no problems whatsoever so far as it's done everything I asked of it, till today........
I needed to drill a hole in the center of a 1" Delrin disc I had, 1/4" thick, no problem I thought so I removed the chucks standard jaws and replaced them with the set of V2PJ Pin Jaws which according to the blurb open up to 32mm and go down to 8mm.
Upon opening them up, the most they'll go to is about 23mm, not 32mm. I'm sure that in the past I've used these jaws for 1" stuff (25mm) so cannot for the life of me see why they hit the stop before they're open wide??? I took the back plate off to see if there was anything obvious, but there isn't, everything is clean as a whistle inside.......any ideas anyone please?
