Tays Doubleboost project

[taycat]

watching Doubleboost with my little brother other day when he trued something up using bearing on shaft.
Tay liked idea and wanted to make one so we did.
This is his 2nd go as made shaft bit under first time and bearing was sloppy fit.

Trueing up something circular to be turned in the lathe chuck ---Chuck

 

[DanielW]

I'm still none the wiser...chuck.

Hello Daniel,

if you chuck a relatively large diameter short job in the chuck the chances are the front face will not run true. Press the outer race of the bearing gently into the job will bring that face true. I use it for edge finding in my miller.

Well you put summat in the chuck and spin it, it may wobble so one way to true it is to use the flat back of a cutting tool to push up against it and force it straight,doing it DB way using a bearing puts less strain on the lathe

Watch Doubleboost's most recent night cap video, he shows it there.

Ah its about the wobble on short stock pieces and getting it straight think my method I use is better.

I have turned a bar of Aluminum so that its the length of my spindle shaft and the diameter is a snug inside diameter fit,feed the bar up the spindle from the back of the headstock,put the short stock piece in the jaws,push the piece against the bar and tighten the jaws.

Usually it works out nine times out of ten that its centered due to the bar being a snug fit to inside diameter of the spindle.

I had to read this a few times before I understood it.

Its fine with large stuff but a mod bar for small stuff has to be made,ie two collars of internal diameter of spindle with holes bored through collars and a 20 or 25mm rod going through the collars to which the collars are kept in place with allen screws.

How many Tays are there? Is it a first name or nick name? I seen your late father had the name and yourself but seem to also refer to your younger brother(s) also with it.

 

[MattF]

I believe, (or assume), his username is a combo of his younger brother and sisters names.

Once again brilliant John

There ya go, easier to show you, but dont ask me what he is saying though coz i work off the pictures, apart from the numbers, because he doesnt seem to have a code for them !!

Mattf is right name was born one night when dad and uncle sean had had a few homemade brews and were planning something.
dad missed letter out of sis's name, although mum was impressed he managed to write anything down.

I'd always assumed it was a colloquialism from Yorkshire, like how people in Newcastle call each other "pet".
