24-90 lens hood repair

I wonder if anyone else has broken or (more interestingly) repaired the hood for the 24-90 lens. I broke mine putting my bag down heavily. I must remember not to get tired in the future. I bought another hood (abt £150!) but I'd like to repair the damaged one and go out and about with it, reserving the new one for the studio. What I'm really wondering is what glue others have chosen and was it successful. I can repair the outer shell of the hood with gaffer tape but I really need a strong glue to re-attach the hood to the ring element - if you own one you'll know what I mean here. Thanks in advance for any suggestions

 

ps or if any materials experts can divine what the hood is made from, I can probably find an appropriate glue by searching on that.

I cracked the area around a couple of the tiny screws (visible deep inside from the front of the hood) where the bayonet fitting is fastened to the body of the hood. 

I took out the 4 screws and removed the bayonet ring. I then carefully applied Araldite (epoxy resin glue) to the broken surfaces of the main body of the hood, pushed them together and left it until almost set. Then I refitted the bayonet ring and gently tightened, but not over tightened, the screws.  The joined surfaces are almost invisible from outside and the repairs can just be seen when looking inside at the damaged area near the screw heads.

I'm delighted that has done the trick and I hope this helps you...

Best wishes,

Graeme

Thanks Graeme,

Yes, I think I'm going to take the same approach with a small change - I'll put some black powder in the epoxy. I think my broken hood parts are probably going to be a bit more obvious than yours. But it's helpful to know epoxy glue works.

Thanks

 Yes, mine was cracked at 2 of the 4 small screws.  I used a needle to apply only a small amount of epoxy. Good idea about the black pigment too.

One tactic that may help is to use epoxy soaked gauze over a big crack to strengthen the structure at the fracture line.  (I used a piece of bandage).  Inside the hood it will not be visible!  I've tried it on other things - mainly children's favourite toys in the past, and though it doesn't look good it works and keeps the item functioning.  

Always worth a try for the price of a tube of glue and a bit of time before laying out cash for the cost of a new one!

I trust it works for you.

Best wishes,

Graeme
