I just bought a 25lb CQR off ebay. It is to be a replacement for the fairly useless Britany which came with the boat. I didn't expect pristine but I'm worried that the pivot hole in the shank seems badly worn. It is slighly oval and at worst (when you tilt the shank) has about a 9mm gap between the pin and the hole. It doesn't look like it could come apart, put can someone tell me how much play they usually have?
 
As long as you are absolutely sure that it can't come apart it'll be fine. They do normally have a good working clearance to avoid jamming, so unless it looks dangerous it will be fine. Fair wear and tear.
 
Does the worn joint allow the plough to move away a lot from the proper angle of attack ?

If there has been a lot of wear, or distortion of the hinge due to overload, then the integrity of the hinge joint might be at risk. Can you see any evidence of metalurgical damage in that area ?

BTW - is it a genuine beduine CQR or one of Al Fiz Weekend Special ex-Landrover chassis ones ?
 
There is no evidence of any damage as such (I guess you would have to crack test to know properly) it just looks like a lot of wear. This must mean that the shank can move a few more degrees 'up and down' than otherwise.

Actually I'm curious as to how an anchor gets this worn in normal usage. Looking at the feedback for the guy who sold it me, he seems to have lots of used anchors for sale. I wonder where he gets them from. . . ?
 
On a genuine CQR that joint is quite sloppy, so I think you are alright. The joint is forged in one peice, hence its integrity.
On CQR clones they often use a steel nut and bolt for the joint which provides a weak link, and usually rusts in the first year of use.
 
Many Plough copies develop that oval hole due to the cast metal being less resistant to wear. As others have said - as long metal is substantial around then it rarely a problem, as it helps the plough set.

My clone is the standard Plough and has not suffered rust of pin unduly. It has same appearance of similar CQR genuine after 30 odd years.

and believe it or not - it hasn't been painted !
 
Can you post a photo for us to see.

Genuine CQR's you should be OK.

There are two other types of CQR copies I've seen on the market at boat jumbles etc.

The first has a decent finishing at the articulating joint i.e. no chance of it coming apart.

The second type I've seen has a washer and a large split pin holding then together at the articulating joint. I wouldn't trust that type.

If it is a genuine CQR, and the seller said he has loads of them then I expect he buys them at MOD auctions ex Royal Navy Anchors, and selling them on.
 
How opinions vary, my mate with a van de stat 35 steel yacht (in Brittany actually) swears by the Brittany that he carries, and I prefer the CQR yet have never used a Brittany /forums/images/graemlins/confused.gif
 
I have a genuine 25lb cqr which came with the boat, and which I have subsequently upgraded to a more suitable size. The original also has the oval wear at the pin holes, which I attributed to the plow not being tied fast when underway, and being allowed to swing - constant small movements over time presumably caused the wear.

Weather today is -3C, freezing sleet / snow blizzard ... boat is on hard next to my cut of the river ... I may delay taking a photo for a while !!

You must be getting soft in your old age /forums/images/graemlins/laugh.gif

It's a calm "cold" 10C here. /forums/images/graemlins/smirk.gif
 
Thanks for the advice. Hole is 30mm in diameter (35mm at the oval) and the pin 22mm. The shank can tilt about 15 degrees because of the play.

It has "CQR pat pending" cast into the shank. I'm guessing its a genuine early model.

I like the idea of teh wear being caused by it being left swinging. That seems to stack up.

On the basis of this advice I reckon I'm Ok, so thanks again.
