Machine Tool Arbor Spacers

Anybody out there inventory arbor spacers in wacky thicknesses? I need four different spacers for a .875" shaft, ranging in thickness from under an inch to right around 1.250". But the exact widths aren't "nice" numbers (for example, 1.013).

I realize I have the following options, as well:
1) Make them myself (which I might end up doing)
2) Assemble a "set" of off-the-shelf spacers to equal the desired amount (however this is a production environment where changeover is key, so reducing parts helps maintain friendliness between us engineers and the tool crib guys).

Social Security Question

So, as I approach full retirement age, I'm thinking my health is good, my job secure, why not keep working, draw Social Security and put the SS away for a year or 2 and let it build up. Will the Social Security be tax free or will that be considered taxable income ? I plan to talk to my accountant when I have my taxes done but that's not til next month. I figure some one here is already in this boat so what's the bottom line?
Thanks,

New to machining: how to use pressure knurlers

Hey everybody,
I'm relatively new to machining. I've taken a mill class and a lathe class at the local community college to learn the basics and I will figure the rest out with a little experience. I've got a question pertaining to pressure knurlers. I know these are inferior to the saddle knurlers, but those are pricey and I'd rather make due with my pressure knurlers for the time being. Is there a way to get a nice looking knurl from this type or should I expect a mediocre finish from these? When I knurl, I am always getting a double knurl pattern, I don't know how to correct this, is it just a matter of raising or lowering the knurl wheels? When I set the wheels up, I give them a slight offset to the right or left, I read to do this somewhere. I'm sure people are very good at this type of setup but I can't get good results thus far. Also, I am using a phase II setup so my toolholder has the knurls built into it. Thanks for the help.
Andy

Bending 3/8 diameter titanium

Anything special needed to bend up some handles? They are a U shape roughly 8" by 5 inches with a 3/4 radius on the 2 inside corners (90 degrees). I have never bent any of this, will I need heat? Cracking or breaking an issue? I can make any kind of bending blocks I need, just wondering if there is more to it because of the material?

how thin can you dress a grinding wheel down to

Want to sharpen the annular cutters today, some need gashing first, if thats the correct term...cutting away some material between teeth (all done on a T&CG).

Not sure what to get in there with.

How thin can I dress the last 1/2" of grinding wheel and still be safe?

How to package VERY small parts for shipping

I have to ship some very small parts I'm making and just about anything I come up with seems hokey. I need them to be kept from being lost. A small 2" x 2" re-sealable bag is cavernous for the parts, and my thought is that it would cause more grief than relief when customer tries to remove the parts. Right now I am leaning toward sticking them on a small piece of Scotch Tape and then sticking that to a small piece of clear Mylar. But while that seems best for logistics, it seems really hokey to me. Parts are for all intents and purposes .100" Long x .002" Diameter. Figure 100 pieces, approximately. NDAs prohibit me describing them much beyond that. Anyone have any nifty ideas that will at least look professional arriving? Thanks
