Re this digger machine track roller

[solarman216]

So here we are waiting for a new billet of steel to make a new track roller for this obsolete digger, Rick

I was going to ask you if it wouldn’t be quicker and better to make a new one. As the old one didn’t look too well.

The first time I saw it I thought I could get a couple of bits of thick wall tube and make one up but stock tube is not available in the sizes I needed so started hunting billets, and struck lucky, I needed 100mm round by 100mm long and this firm had just the one piece for £20 quite looking forward to some nice heavy turning, bought a couple of tungsten tipped boring bars as well for total £9 I have loads of other tool stock but always been short on boring tools so this was a good excuse to get some more, Rick

Looking forward to some pictures of the turning process Rick :thumbs

 

[solarman216]

Yes start to finish, Rick

Billet turned up today, first job was to centre drill it

 

[solarman216]

Then feed in a 25mm drill right through

 

[solarman216]

This gives a bore big enough to get the boring bar in later but for now I can use a live centre to stabilise the job in the chuck while I turn down the outside

 

[solarman216]

Trueing up the outside

 

[solarman216]

Facing off the end ready for when this end goes in the chuck

 

[solarman216]

Turning down to the 80mm ish needed

 

[solarman216]

Just got to sort the corner out and remove the 5mm on the end as it is too long

 

[solarman216]

One end sorted more tomorrow, Rick

 

[Flying Torquewrench]

Nice work. That will be a lot better then the old roller.

 

[panelbeater]

nice but why you doing it dry?

 

[solarman216]

nice but why you doing it dry?

Because I do not have a tray and other stuff for soluble oil turning and most of my other turning is much smaller and brass or Ali so not worth the trouble, Rick

 

[panelbeater]

ok.

 

[solarman216]

2nd half turned to size

 

[solarman216]

Now to start boring, I have a much bigger twist bit some place but cannot find it

 

[solarman216]

New boring bars are not a patch on my old one, probably as old as me
