[Emc-users] Spiral spring covers

[andy pugh]

Does anyone know a cost-effective source of spiral spring covers?

I have just been quoted £125 each for a pair of spiral spring
leadscrew covers for my lathe (£318 delivered in VAT) by Beakbane. DQR
didn't even bother to reply.
Given that the ballscrew + double ballnut came in at £170 this seems
somewhat excessive. Does anyone know where I can find some that I am
prepared to afford?

These are not much more than a version of a plain clock spring. I
imagine a bit of modification to a large clock spring or get a spring
from one of the pull out barriers used in public areas trade name was
tensator iirc

Hi Andy, I have some of those you can have, I will measure them up. I can 
probably get them as far as the uk as my aunty is going home tomorrow. 
Good Karma for answering all my questions!

Hello Andy.

May be this site could help you, they manufacture covers and I think they
can do what you need. I don't know about the cost but you can ask for
quotation. The only detail is their site doesn't seem to support english
although there's the EN button there. They are in Spain.

Here is the web:

I hope you can find a reasonable price.

Leonardo.

I am rather committed to one that is 50mm wide, which would be quite a
big clock spring.

I imagine that those are quite small, seat-belt sized at a guess.

I rang DQR who import theirs from Germany, and the price came in as
£41 each. Quite a difference.

the tensator style are also used as constant force for tool balance
purposes and can be almost any size to suit.

I think the only one with ballscrews that fat is probably Sam

I went out to measure what I have - One is 50mm wide, and 2 more at 75mm wide. 
id of the coil is about 80mm i guess. 
They are new, but have sitting around and there is some light rust in a few 
spots.

I ran into that same problem Andy, and at one point considered to the 
point of tearing a cheap tape measure down to get its rewind spring, but 
could not figure out a way to rivet a piece of it so it would 
automaticly and evenly expand and contract.  Every way I came up with to 
fasten it, also restricted the ability to assume a suitably relaxed end 
to end tension.  That, combined with losing an inch on the right end 
travel, turned it into a "let the felts in ends of the nut" handle/wipe 
the debris from the screw.  Thats worked surprisingly well so far.

I can't say the same for my efforts to put felt seals on the rear of the 
X carriage, I keep running into the brass plate I extended forward from 
the motor mount to cover the rear of the x slider, and my motor folds it 
up like so much TP. So there is a sound of a bit of stuff in the x nut. 
But the motor has the power to mash it into the screw so its still 
working well enough.  That was an 8mm screw I got some of from one of 
our PMDX people, and the nuts, while flangeless, also did not have any 
felt wipers.  Hence I tried to seal the top of that gap at the rear. My 
x motor is on the rear of the carriage, which adds zero weight to the 
front V-way, demanding a tight gib strip.
 
I should someday, (when I find my missing round tuit) fabricate another 
nut holder with some old felt hat for wipers, like I did on the toy 
mill, but thats also a source of some give in the mill, requiring a huge 
preload tension to crush the felt, and the lathe is a lot more crowded 
than the toy mill is at its worst.  So the nut in the lathe was smashed 
into a cage, that is pulled  back closed over it by the cages mounting 
screws. The cage was made about a thou short of the nuts length & 
chamfered & stretched that much to get it trapped length ways.

Cheers, Gene Heskett

Too late, I have already placed my order with DQR.

I am rather committed by other parts of the design to the 30-650-50 size too.

It seems that some places are much more reasonably priced than others.

http://www.aliexpress.com/item/telescopic-spiral-spring-cover/32305550135.html?spm=2114.01020208.3.210.U3jqAs_ab_test=searchweb201556_2_71_72_73_74_75,searchweb201527_2,searchweb201560_9

Looks a bit vague on sizes but presumably that $20 is for the smallest
size listed.

I imagine that they are made with a simple set of three rollers and an
angled entry guide.
