Belleville washers (springs)

[dlane]

Anybody know a good source for 4-40 (.200od, .118id ) Belleville spring washers,
The places I've checked want over a dollar a piece with a minimum of $50.00
McMaster didn't seem to have them that small.
Thought about getting flat washers making a die that would fourm them then temper them
Thanks

Fastenal showed on #4, is that too big?

A 6" vise is overkill for a RF45 style mill. A 4" is more appropiate for that size mill & IMO 5" max. I have a 5" GMT vise on my PM45 & it's slightly too big. Not enough Y axis travel to make use of the 5" full capacity. Better to save your money rather than getting something too big & most importantly the weight. I take my vise of the table quite often, a 6" is still light enough for me to be carried by hand but I'm glad I have a 5". I also have a 4" vise as well. I prefer the 5" though.

But those GMT 6" Premium vises are pretty nice. I'd love to have one but don't need one on my current mill. But if you plan on upgrading to a full size knee mill in the future than the 6" will be perfect.


Here's what the 5" looks like on my mill.



I couldn't even complete this cut without my bellows & DRO scale getting in the way. Not enough Y travel & the 5" vise is not even maxed out.



Here's what a 6" vise looks like on another PM45 (gt40's)

Thanks Roy, ya I checked with them and .250od is to big for this application .
Advanced spring has them but they want too much for them and couldn't tell me what shipping would be?

Derrick---sorry---so far I have not found any tiny ones yet---after my move 6 years ago I have not got all my supplies organized ---I'll continue looking----I thought I had them with my tiny snap rings and e-clips, and tension washers---Dave
