Unwanted taper
1st a thanks to those who suggested my Speedway 7x12 speed control issue was most likely a bad pot.? I replaced it with some major surgery and it¡¯s fully recovered and working like new.
Next problem is the unwanted taper I get machining stock longer than a few inches.? This happens whether I¡¯m turning between tailstock and 3 jaw chuck or between centers.? I¡¯m not a machinist an have no idea how to solve this issue. For measurement I have a magnetic stand and plunger dial indicator.? But how to use them to solve my taper issue is a mystery. Is the an easy way to achieve?this? Tom P.S.? I use my lathe in building bamboo fly fishing rod hardware. |
Re: A Great Bit of Craftsman Machining
What I'm trying to visualize is where on the lathe you installed the oilers.? On the ways - like drilling through the ways?

Dave,
Have you ever thought about proof reading your messages before sending, instead of sending us your first draft, then an edited one?

It need a oil film so have not metal to metal. This also turn on all screws and nuts. A haft nut will last for ever if has oil. No oil very short life. Installing simple 4mm size use a 4mm drill.

Re: A Great Bit of Craftsman Machining
I think I have some of these lying around that I never put in. Is there a recommendation on the appropriate hole size to get a good fit?

Re: A Great Bit of Craftsman Machining
OldToolmaker 4:40pm? ? Dave, While I agree taper roller bearings are not expressly needed on the minilathe they do fit and work well in this application. I have used both in my minilathes. The ball bearings are quieter. I don¡¯t agree that a zirk is required The Zirk in the correct location will push out the old grease.? But flip side almost no one use the zirk after first week.? I have install thousands of zerks knowing the odds of them use was low. But there are seal not {shield or open} and pack with grease before shipping.?? I like seal ball bearings just install and no worries for 30 or 40 years.? Dave |
Re: A Great Bit of Craftsman Machining
Dave,
While I agree taper roller bearings are not expressly needed on the minilathe they do fit and work well in this application. I have used both in my minilathes. The ball bearings are quieter. I don¡¯t agree that a zirk is required. The taper roller bears will run for years with just a pack. Occasionally I would open the headstock and give the taper roller bearings a shot of spray grease with a straw tube. Easy to maintain and not messy. Dick |
Re: A Great Bit of Craftsman Machining
The tapered roller bearings have great load capability at lower speeds.? It is over kill for this size lathe . There are down side from a tapered roller bearings over a seal ball bearing. Lubrication most just just pack . It need a zerk? for grease? Installing needs in very clean room and may need more parts to seal the tapered roller bearings most skep this part.? Other than that is great bear for a oil bath head stock.? The capacity of a 6206 is 2,500 pounds? https://www.mcmaster.com/5972K342/ Dave? |
Re: Morse tapper in tail stock
¿ªÔÆÌåÓýI got a MT2- JT2 adapter like this (might have even been this one from Grizzly )?I had to cut off the tang and enough of the shaft to get it to fit the tailstock; it wasn¡¯t hardened so it was easy. I even have a genuine Jacobs chuck, but it¡¯s one of their low end cheap ones made for the big box stores.
