Hello..

I watched all the vids on the ball turner.. I like your idea and thought you made a very rigid unit I like it and strangely enough I have all the material to make one myself.

Could you explain a little more why you were acorning, and was the mandrel sticking out of the chuck too far causing it to lift and chatter.

All the best..

Anthony.
If you cant fix it, get another hobby.

Nice video Skyrocket but I have to ask. When you reach to turn the camera off between shot you let out a deep sigh or you might even call it a groan, made me smile and I found myself waiting for them.

Cheers

Skyrocket great ideas however I am baffled as to why you didn't make your own spring??? for the tapper following steady??

I have not done it myself but seen a mate make one for me prior getting a lathe.

I know we all think of these things after the fact, still now you have a wide selection of springs to make more stuff with.

Hello Anthony ,  the acorning was caused by me not setting up the device in the correct position , luckily there was lots of help on the comments section below the video on YouTube with people with more experience of these matters putting me in the right direction,check them out
Re the chattering I didn't get to the bottom of it, I couldn't get it to cut brass on the rear cut, but it was fine on steel,
I made the device for a sculpture I'm making at the mo, overall I'm happy with it but it's limited to balls 30mm max lol which was fine for the project

Like your version of the ball turner   :thumbup:  . Going back to your vee block; I noticed that you were using a MMA welder, I assume it was one that you plugged into a 13 amp socket; what amps were you pulling & what size rod used, did you have a separate circuit installed?.  last time I did a bit of welding I used a 1.6 rod & was set at approx 95-100 amps, but that was a long time ago & I'm concerned about using the house mains through a 13 amp plug (it must be my age making me a bit over cautious now   :palm:  )

Get an inverter mma welder if you are concerned re: current draw. Their inrush current is far less than a buzz box transformer type.

I have one that you can pick up with one finger, but also run a 3.2 mm electrode on the end on a long 13a extension lead. Excellent for things I cannot drag into the workshop. It also starts rods such as 7018's so much more easily.

Mine is a Cebora, and I got it at my usual tool shop - ebay  :ddb:

Not sure if this is the exact model but very similar:

Thanks Andrew

Hmmmm, nice, but for what I do, & on my pensioners income I can't justify the cost...  :jaw:

Yes expensive new, hence getting mine s/h on ebay - I think I paid about £60, certainly less than £100

  Hi Sky, like your knurler, seems to work very well, and designed around bits and bobs you had available. Nice video.

                                          Well done  David
