Titanium...nothing new, it's been around since the 1790's when it was first discovered in Cornwall, England of all places, most probably in the tin mines there!
It's found in all living things but principally rocks, water bodies and soils.....titanium can be alloyed with iron, aluminium and other metals to produce strong lightweight alloys for aerospace, the motor industry, orthopedic implants, dental instruments....the list is endless!
The two most useful properties of the metal are corrosion resistance and the highest strength-to-weight ratio of any metal.......
Why am I interested in titanium????
Well, I wasn't!
I found a supplier in the UK for longarm needles...just like the ones I always use.....that's what I thought....until they arrived......then I realised that these were not my usual needles but titanium coated needles.......after a discussion on one of the forums I frequent I realised that lots of people were very happy with titanium needles....they keep their sharpness longer, they are stronger, so don't break as often.... so that makes them cheaper right?
Sounds great doesn't it....until you break one!
This is the first and last titanium needle I will ever use.....That was friday evening 1st April....some April fools day huh!
Can you see it.....look in close....that needle snapped on the intersection of a quilt block....this is a beautifully pieced quilt...it's not an exceptionally thick corner but maybe 6 thicknesses of fabric....that needle was jammed in there and not going to budge.....it blew the fuse on my machine, it blew two fuses......which probably saved anymore damage as it took a while to really realise what had happened!
I eventually realised that I had to do major surgery on my longarm and remove the hook/bobbin assembly.....I was supported through this by some wonderful assistants on the APQS forum...lol.....
I couldn't remove that needle, my DH couldn't remove the needle, I tried again but had to admit defeat and ask my DS who put the hook in a vice and with one sharp tap released the needle!
Did you ever wonder what your hook/bobbin assembly looks like totally dismantled.....
Now, all joking aside....the hook/bobbin assembly is now put back together and in my machine.....I had to re-time my longarm!!!!
I can't test it out just yet as my good friend Linzi has posted me some new fuses which I expect to arrive tomorow.
Although everything looks and feels OK, I do not anticipate that the following days will go smoothly......I do expect problems and will be ordering a new hook/bobbin assembly which will probably take a week or so to arrive!
If you are thinking about the merits of using titanium needles, think very carefully....a pack of ordianary needles is quite cheap...a new hook/bobbin assembly is not so cheap!
So why did I bother going through this proceedure...when I intend to buy a new hook/bobbin assembly????
Well, there is an up side to this.....I learned sew much about my machine this weekend....I am now not quite so anxious about having to do service on her...we have become better acquainted with each other.....that can only be a good thing!
My longarm is very precious to me!
