Tips/Techniques For Chawbeef -- feed screw shield

[Ironman]

My lung clots are doing better and I finally got the pictures you PM'd me about.
When installing these covers, the nylon end must be free to allow the feed screw to rotate while the shield is stationary.
The tricky part is to get the diameter right on the big end so as the shield shortens up, and the big end expands, there is room to do so. My first attempt was a fail as I measured the collapsed diameter as it was shipped....and it needs to be about 3/8" bigger than that.

Is there a source and right and proper name for the coily stretchy bit here ?

I'm trying to understand the Ali ordering description. For example, 25-400-40-38:

The following guesses may be incorrect......

A) 25mm is the small end diameter, needs to be slightly larger then your leadscrew?
B) 400mm length when extended, needs to be long enough.
C) 40mm is the minimum compressed length
D) 38mm is the large end diameter and your cup to hold that end needs to be slightly larger than 38mm to accommodate it when the spring is compressed?

Please correct if my guesses are incorrect.

Of course, you can't really ever trust Ali even when it's their own description...... LMFAO!

I think you are correct, but you can verify with them on their "chat" thing.

And If you or they are wrong, are you going to bust a gut over a 6 dollar item? when this country wastes a hundred times that, every second?

Sure "Sweetheart", their chat is the most reassuring verification imaginable! (He says dripping with sarcasm).

Good point. In fact, that's really the whole point. Their low prices do vindicate the low level of certainty. At least from my point of view it does.

would you be happier if you paid 10x from Centry Covers for the exact same item from the same factory? I can't see anywhere on Centry site where it says Made in USA, which generally means it isn't.
