What are you machining?

[The_Yellow_Ardvark]

Fish?

No Thomas the Tank.

 

[Woody.v8]

No Thomas the Tank.

Is that a euphemism?

 

[Barking Mat]

Been milling wood, yes wood.

Wifie wants me to build kitchen cabinets.

Well, an entire fitted kitchen.

My issue is wood bothering, I'm crap at it.

Then I remembered I'd bought a mill.

Might improve my tolerances...

I chucked some bits in the mill and had a play, looks promising...

We'll see.

It was just an experiment...

 

[Barking Mat]

Ooh, that's a crap photo.

Looked ok on my phone, but No.

 

[Hood]

Not going to like that, have bad flashbacks to turning wood on a metal lathe, took me years to get the sawdust out of it.

 

[Hood]

What's that, about 340/350mm?
Must be a bit taller than the Computurn on centre height I think as it has 435mm or so across the bed which should allow for more swing than a narrower bed.

Don't feel beaten @Hood .
It's not the size, it's what you do with it.

Ha ha I am not worried, just trying to get a handle on the relative size of the two lathes. The Mastiff looks a bigger lathe but in reality it is not that much bigger just the Computurn is like me, dumpy

Nothing I guess, though I don't know if the access would allow it. I just found a picture of the BMW tool and made something similar.

Nice job for a 3D printed part.

 

[Kram]

Finished off the pressure turning. Wanted to put a radiused edge but I dont have a tool for it, I do have a wood 3mm radius cutter. Setup was a pain, had to run in reverse.

Delrin stringers are everywhere, like it has been snowing!

Made a propshaft adapter out of 150mm en19t for a mates overlander.

That is cool, would have never thought about doing it like that but seems so obvious now.

 

[Pete.]

Made a couple of steering rod adapter bushes for fitting a different model's steering rack to a drift car. M16x1.5 male thread and M14x1.5 female.

First time cutting a taper quite happy with this 30° cut

 

[Kram]

Thats an unusually clean lathe what is it?

I spent too long looking through Zoro and Amazon, decided to make it, 1/4" bspp thread turned for a 90 degree hose tail. Should measure 13.51mm, got 13.48mm.

Not mine unfortunately

One of the new Colchester students , don't make em like they used to but still alot better than messing about with my Chinese mini lathe at home.

Even more tempting to try and cram a big lathe into my garage after getting to use this for a while , carbide quick change tooling is also a difference and nice to use

Very nice. What rpm and can you take a close up of the tool tip please?

 

[Lewis_RX8]

Thanks

1700rpm and what I would to refer to as a finishing tip I'll get a pic of the box next time for the exact number , very nice to use and easy to get a good finish in my experience if I'm at a higher rpm and decent feed rate.

This is the tool here as I said not certain on exact tip but will find out

No that's great thanks.
I also use these pointy tools for light cuts and finishing. They give a much better finish especially on my old Triumph lathe which only goes to 1000rpm.

Agreed far nicer finish every time changing rpm depth of cut etc can change it so just about playing about with feeds and speeds etc and when I get a good finish then taking a note so you don't have to repeat that process again and can go straight to the best finish parameters.
