Curved segments

Thanks fellas, just thought I'd show you that I'm still spinning over here.

Making curved segments ? easy really once you've found a method of keeping adjoining faces square to each other.

Most of the process is shown on our UKWorkshop forum,

There are a couple of images missing, don't know what happend to them.:dunno:












:rofl:

Either you are magic with wood or you have a magic wood scrap box.
.
I'm afraid you must do your scrap shopping at a different store than I do!
Well having friends who burn the scraps from a funiture manufacturer for winter heating tends to mean you end up with more bags of the stuff than you know what to do with.

Thank you Chas, for taking all that time and effort to document the process so well. Managed to follow each step and understand how it was made. I think its time i got myself some Cole jaws.
I have made a longworth chuck but either i did something wrong but it does not seem to apply the pressure or resultant fit such that the item being turned is clamped central. I can see where cole jaws will do a much better job. Any other alternatives that you could suggest?

In all honesty Rob, I think forking out the hard earned on a set of Cole Jaws is the best solution in the long term.

I have made longworth chucks, home made cole jaws etc. in the past and all had their limitations.

As you say getting a longworth chuck to clamp with sufficient pressure to turn something like the segment ring is neigh impossible, fine for cleaning a bowl base up with tail stock support but that's about it.
Home made Cole Jaws, unless you have the means of drilling the fixing holes with the accuracy of a dividing head etc. much the same limitations on run out but with better griping power.

Cole jaws can also provide a good (adjustable face plate) clamping base for odd shaped pieces with the use of some threaded rod, long bolts etc.
