Metal Spinning
« on: July 21, 2008, 10:10:23 PM »
I am starting this topic to continue the discussion started on the "Little Bit Of Everything" thread.   

Since the discussion was turning more to spinning I thought it might be better to start a new topic.

This is funny. I have alwayse wated to try this and I just rented the two part video on spinning. It looks like lot's of fun. There are a few videos on Youtube also.

Wes
Wesley P
A Gismo ??? If it has a flywheel or spins and is made with small parts. I'll take one! If it makes noise, moves, or requires frequent oiling and dusting it's a better deal yet. It's especially right if its shiny and bright; but if it's dirty and dull it wont mater at all...

I like the first link with the guys home made spinning lathe. Gives me inspiration.

I've got all three of Terry Tynan's dvd's... I just haven't watched and absorbed them all yet!  ::)

I am going to give it serious studdy.... I want my spherical boilers!! (And other shapes too!  ;D  )

Yes Eric.... you know what I am aiming to build!!  ;)  Wind ball  ;D

Try buying a circle cutter on impulse off Flea Bay....(bout 8 months ago) 260.00 ($520.00 ish) ... I thought it would help me in the start of my spinning endevours!!! It only cuts 4" - 36" circles!!!!!!!!!!!!!!!!!!!!!!!! I didn't realise it's size  :o !! (It's damn heavy too!)

Still a reliable source told me it is worth about 600.00!!


I'd better get some tooling made and some spinning done!

I just need to figure out what I need for tooling. Gotta get the videos.

I have a few other things I want to make with spinning in addition to the windball...

BTW... I listened to CD#6. Music is cool but WTH is he singing??

Hey Roger,

You won't regret asking that question. The windball is actually a aeolipile. Otherwise known as the grandfather of all steam engines. Here is a fantastic reproduction:



Check out this Guys Site. Amazing stuff!

Still haven't figured out what kind of lube they are using during the spinning?

Wes

Wes:

The lubes seem to be pretty much an experiment in alchemy.  The local spinner here uses a concoction of wheel bearing grease (ball bearing), shaved soap chips (Ivory soap), and enough linseed oil to thin it to the desired consistency.

Terry Tynan sells a wax based lube that he prefers at the Metal Spinning Workshop Forum:  Scroll down the page to find the lube.
http://www.metalspinningworkshop.com/Other_Items.html

I have heard and read where old time spinners used sheep tallow for lube, but that is impossible to find anymore.  Whatever lube you end up with it should be used sparingly as it will sling off and since you are working in close proximity to the work, you will end up wearing it.

The one constant I have found in metal spinning is that there are no constants.  What works for one shop, may not work at all in another shop.  Since the trade seems to have been passed from generation to generation, techniques and materials seem to be as much a matter of personal preference as anything.

OK!  As you all know you find information in the most obscure places and at the oddest of times.  While searching for an owners manual for my latest band saw acquisition, I came across this posting in the Old Wood Working Machines forum.  The post details how a very talented wood craftsman went about making an ELABORATE spinning chuck for a pewter tea pot being reproduced by an equally talented metal spinner. 

This gentleman documents his posting well both in text and photos so enjoy.  Also included in the first post are some photos taken at the spin shop.  The spinner has some of the nicest equipment I have ever seen.  The Prybil is a thing of beauty!

http://owwm.org/viewtopic.php?t=32108

In a follow up post Mr. Thomas shows the tools and methods he used to make and fit the handles for the tea pots.  Included in that post is a photo of the finished project and it is worth registering just to see it.

http://owwm.org/viewtopic.php?t=39251&sid=791d8f2611ca2ef3a64af421bf4a5a58

Also Wes in the photos taken in the spin shop one picture shows a rolled up towell tied up with string.  That is a cloth soaked in lube and then rolled and tied for use as an applicator.  The spinner touches the end of the roll to the spinning disc to apply a small amount of lube.

I'm currently waiting to get onto the forum to find these links you gave.... I have to be cleared by the admin!
I'm also currently thinking about a design for a tool rest/fulcrum point that will mount firmly on my 9x20 lathe... when I have one that I am confident of I will post my scribbles!
For some unknown reason I can't seem to find much time for the shop at the min? We (the Brits) are having our half ass attempt at a summer so I seem to be trying to enjoy it.... Don't know what that's all about!!?!?  ;D

Thank you for your postings Roger, I really need to get this one sorted.... Got to make a windball!!  ;)

If your interested in pewter here is a site for casting and spinning pewter.
http://www.aslpewter.com/.
they have at least one DVD out on spinning and working pewter. and For the US members you could rent it at Smartflix http://smartflix.com/
It is a very well done video on the basics of working with pewter including torch soldering.

I've got to get my tool rest and tools made... I need to try the spinning out.


Glad other people want to do it too... This means that I can learn from others trials too  ;D

Interesting to see that nail in the centre of the form. never seen that before... could stop a super fast spinning circular razor blade from launching across the shop!!

Ralph.

Center pins are not uncommon for exactly that reason.  The downside is that they do leave a small imperfection that will need to be repaired on the finished shape.  Even with the center pin it is probably still not a good idea to stand in line with the spinning disc.  Also it is a good idea to recheck the tailstock center for clamping pressure after the first pass or two DAMHIKT.  If the tailstock should loosen up the metal can chatter and destroy itself by tearing.

On the other hand the center mark on the windball halves will be desirable as it will mark the concentric center of the hemisphere.

Yes I was thinking that the one part would need a hole so it could be a hole from the start, it would also make it easier to hold when soldering if the hole is there.



Some projects still to move and then I will have space to start the afore mentioned tooling  ;D

Actually the problem this weekend is the model show I'm going to in 5 huors time... leaving approx 5:30 am and driving for 4 hours to get there..... Thats a long way on our little winding roads!!

If there are any things deemed appropriate for this site I will photograph and post them..... Mainly going for the model engines etc though   :thumbup:
