Leather Lifts Up With Needle - Need Help - At Wits End!

I am running a 441 clone with an oil pot and using silicone oil in the pot, yet the same type of issues still occur, and If my recollection serves me right I did a search for titanium needles sometime in the past when the same issue presented itself.  Wiz if you know of a dealer who has the needles in 25 for 277 thread please let us know so that they can be look at for price comparisons.  I have a recent post up that is asking the same type of question with a little different twist to it.  In fact one the most interesting things that I have happening is that when I am sewing 2 layers of 9 oz wicket and craig leather I will actually have some squeaking going on as the needle is going through the leather, this is after it has been glued together using Barges glue after it has dried for at least a day in warm to hot days or put on a forced air boot drier when the ambient temps are low.  It is the weirdest thing to hear and watch.  I have gone in and made sure that everything is clean, well oiled and running like it should be a far as I can tell.   

Can you look at you needle package and tell me what point it shows? It could be P, S, D, etc. Also, are you already using a #25/200 needle?

Wiz I am running a 25/200 S Schmetz needle.

Thanks

I encountered a job where the S point gave me fits. I switched to a diamond/triangle point and it did the job without any more issues. The diamond point lets the thread sit on top, rather than getting drawn in on the ends. It gives a more pronounced effect. Bob sells them.

I think that Wiz's original guess that the smaller needle is the culprit is correct. The larger needle has more space to "hide" the thread in, and overall creates a larger hole, so trying a larger needle may actually work.

[OLDNSLOW]

I might be wrong but I think the 25 is the correct size if not a little big for 277 thread,  I was doing a job just a few days before this last job to discover that I had a 24 needle in the machine and you talk about a real nightmare.  I thought it fixed  all my problems when I went to the 25, but it didn't so I am not sure if the type needle that wiz recommends will cure it but I am going to try it.  Thanks for the input wiz I will give a Bob a call as I have a few extra bucks to spare and give those whirl, not a curly wurly, just a whirl.

Wiz I made a call and need a little more clarification from you, is the diamond point or the triangle point that you used to cure the problem?  Thanks for the help!!

The package I got from Bob says "Dia" - which means diamond. The actual geometry is triangular. It has three sides that converge to a sharp point.

Thank You

Part of the squeak and needle sticking problem is Wickett and Craig's leather.  I use both Wickett & Craig and Hermann Oak in the shop, and time and time again, I've had this happen with the W & C when I haven't changed a thing on the machine.

I keep a small piece of bee's wax on the machine and rub it on the needle shaft when things start lifting (usually glue not completely cured) This helps and also seems to polish the needle so it slides out easier.
