Morse taper problem

G'day all

I thought would share this in case other MCxxxx owners are having the same problem. Mine cant possibly be the only one with this fault.

I had been having a problem with spindle turning on the MC1100. Whenever I finish a spindle using bevel edge rubbing with either a gouge or skew I was getting terrible vibration at the tailstock end. In the centre I can understand that, but why at the tailstock end? It was so bad I was getting a mild barley twist

I spent a lot of time a while ago fine tuning the alignment of head and tail so I knew that was not the problem. (See this thread https://www.woodworkforums.com/showth...ight=tailstock) Tailstock was clamped down tightly and shaft was locked in position, so what could it be? I frustratingly asked myself. Maybe it's the live centre. So off to Carbatec and get a new heavy duty live centre. That didn't fix it either. Then I noticed that even when the live centre was driven firmly home into the morse taper I could move it up and down very very slightly. Close inspection of said live centre showed a pronounced contact point halfway down the taper.(See arrow A ) This means that the the two tapers were not a perfect fit and the live centre was vibrating at the business end. Thinking, thinking, thinking. Got it

I asked the purchasing blokes at work if they could find a supplier where I could purchase a #2 morse reamer. Well, they went and purchased one through the company account

Pic 1. It worked a treat. You can now see that contact is being made properly through the full length of the taper. (See arrow B ) I'll get this bloody lathe perfect if kills me

. Anyway I threw a piece of 1inch square redgum between centres, turned it round and bevel edged the the final few cuts.Eureka !! Another engineering flaw fixed on the MC1100. I hope this long winded story is of some benefit to other MCxxxx users and there are a lot of us out there.

Cheers
Shorty

You can get them from McJing in Yagoona - mail order (or personal visit, a bit hard from FNQ!) Good people to deal with. They come as a set, roughing and finishing, or if you only need to clean up an existing taper, the finishing one should be OK. I was having problems with my drill press chuck falling onto the workpiece, a few twists of the finishing reamer fixed the problem.
