Question about adhesives

[matty d]

Hi DIY Novice here.....here is something work related.

I work in rehab on a behavioral health unit. Everything is safety oriented. We have patients use wheelchairs with anti-tipper (wheelie bars).

The wheelie bars are steel and insert into another steel tubing on the frame and have a button lock (like the ones you see when adjusting a metal cane or crutches).

I would like to weld the wheelie bars onto the wheelchair frame. The supervisors say NO because it would void the warranty B.S.

Any suggestions for glue/adhesives or other techniques that will secure the wheelie bars so that patients will not take them off to use as weapons?

THANKS GUYS

JB Weld or 3M epoxy is pretty strong.

replace the button with a steel rivet

 

[Meursault74]

clamp (with a hose clamp) a cap over the button so that the bars cannot be easily removed.

You might want to have the option to remove the bars for transport or storage in the future.

I work in the institutional environment as well. So anything that can be used as a weapon is greatly frowned upon and mitigated. I like the rivet idea but would also suggest in addition too using green loctite 638

I don't think this will work in your "tube inside a tube" scenario but 3M makes VHB tapes that are strong enough to replace welding.

What about removing the button, drill thru everything and just bolt it together?

 

[Sevenhills1952]

Anything you do would or could void the warranty so (to me) your supervisor can't be right...(right?).
It seems to me contacting the manufacturer is the best bet explaining the situation. I'd tell them they have to be modified to avoid being used as a weapon and what's their suggestion?
Your weld or simply braze idea is best, drilling would probably weaken it.

If you want to glue it, 3M panel bonding adhesive should do it.
They glue car bodies together with it.

Acra glass epoxy..........
Put some on the inner tube, slide it into the outer tube.

It will be there long after all of us are gone.

I agree with this, but the cost of the application gun is high.

What about drilling a small hole & installing a sheet metal screw?

Or some epoxy soaked foam behind the button. Once it sets, can't be depressed without tools, meanwhile it appears unmolested.

Loctite Fuze It

 

[rustyjames]

Locktite PL Premium. Cheap and tenacious.

 

[Neggy]

3M or other quality panel bonding materials should do it, but it isn't cheap, the last time go wrote it on an appraisal it was about $70 dollars for a tube.... but when it is applied properly it is stronger than a weld.

Tube inside tube = sheer load.
Use Bostik ISR 70-03 . It stays rubbery but grips like hell.

Tether the two pieces so they can’t be taken apart, but can still be adjusted. You could simply use the existing holes and a small chain that would be held to each side, by a bolt and nut set.

So…..I tried to draw a picture. If it’s clear as mud, let me know. The top part is supposed to be a side view of the bottom picture.
