Cracked lens shade repair


Harbor Freight sells two plastic welding kits and Amazon has several. Just search "plastic welding kit"

I have used metal tape that is like thin foil with a glue back, used for refrigeration ducting and other applications. It is amazingly strong, flexible and permanent. Pick it up at any hardware store. You can use a black felt pin to color it black. Its not pretty but it works. Knowing what kind of plastic the hood is, helps to identify proper glue product i.e. ABS vs. poly vinyl etc.

$$$? I'll admit that I enjoy fixing and salvaging old and broken stuff- SOMETIMES! I keep a lot of adhesives, tapes, and other such materials in stock because I frequently use them for repairs and maintenance of my building, building sets for commercial jobs in the studio, and doing custom picture framing.

Sometimes it just doesn't pay off. Some of these super glues are expensive and do not have long shelf lives. As others have mentioned, thermoset plastic does not respond well to solvent-based adhesives. The application of heat may or may not work. If the repair to a lens shade finally comes apart again- many of these glues will not hold indefinitely, It's not a matter of life and death, but in my experience, things come apart at the most inopportune times in the midst of a shoot.

If a part or accessory is no longer obtainable or I can't do a workaround replacement, then I will try extra-hard to fix it. I once fixed a plastic processor part by taping it together and then dipping it in a marine epoxy resin- a two-part viscous paint with a separate catalyst- $75. a gallon. I had some on hand because, at the time, I was building a darkroom sink. That part outlasted the entire machine!

At 40 bucks, I'd be tempted to order a new shade! Maybe I'm gettin' lazy in my old age!

PS- Here's a neat workaround for $20

Go Steampunk!

Wrap a length of metal pipe hanger around the outside circumference and rivet it on!

(Paint the inside black, of course.)

2 inch gaffers tape and then cover it with your camo wrap. External compression applied to a cylinder, bombproof. 👍😀

Try one of these, they are real handy to have around.
Mine has certainly paid for itself.

Another thought - aluminum duct tape. Very heavy duty, never tried to paint it, but very sticky & strong.

E 6000 glue. Sold at the big box stores and other stores. Works great for joining plastics.

Check out Gorilla Glue tape. As others have mentioned the wall thickness of lenshood is too thin to provide enough surface for effective glue job.

I have used that to repair old garden hoses. It does work, it is ugly.

It's ugly alright but it will save you $53 !!
