i broke the plastic leg off my swivel office chair, the legs go out from the base horizontally, and are weight bearing, and blance the chair,
anyway, i went into the cupboard and found some testors cement for plastic models, would that work? and hold it together without making it flex? im close to panicking now,
and i cant replace it.

if i were you I would go to a second hand store and get another base off of another chair and attach it, my husband did this for his Leather chair he loves so much. and he is happy, it didnt seem to take much to do either. good luck!

This is not an easy one to answer. Plastic is a general term.
Most plastic models are made of polystyrene and the glues for them contain styrene monomer which partly dissolves the polystyrene when applied to the polystyrene. The partially dissolved polystyrene then runs together and the styrene evaporates making the bond. It is a strong bond for models.
Your office chair has to be a different polymer. It may contain styrene but I suspect it is a rubbermodified copolymer or perhaps an acrylonitrile / styrene or similar product if styrene base. These do not readilly dissolve with styrene epxosure and do not weld properly or strongly with the model glue.
A solvent weld technique may work well but you need something that will dissolve the polymer. If you can get tetrahydrofuran (THF) and use this to coat both parts and push them together you may be in luck. Be careful with THF. Use it outdoors and note that it forms explosive perioxdes when exposed to air so only buy a small amount and discard the remains per local disposal laws. THF smells very much like diethyl ether (common ether) that used to be used as an anesthetic.
You may never be able to bond this and get the desired strength.

try it. I'm not sure you will be successful. I keep knocking the plastic piece that holds the wheels on my vacuum. I've tried plastic cement, expoxy and Gorilla glue. None has worked perfectly.
As far has hold together, perhaps hard straps (wood, metal, ?) on either side and then wrap with a heavy duty tape until cured? Don't get the glue, straps or tape mixed together or your chair will have new glued-on pieces.
Plastic gets old and brittle, it is not a long lived product.

Most glues dont glue plastic well to start with. Plastic welding is a professional technique in which very hot air is used to melt identical plastic into a crack/break. This would be the strongest & even this may fail under this type of load.
Its prob time to go shopping.

Your not going to be able to fix a plastic weight supporting chair leg...unless there is metal in the center,if there is then weld the metal...otherwise get a new chair...i wuld get a new one anyways, because even w/ welding the chair will never be the same

The truth is Once anything is broken, it is BROKEN and cannot be repaired. Most of the time. Chairs are the worst . That is why there are so many furniture stores. They don't make anything last for too long as they want them to be replaced often so all will have jobs.
If your product is too good then your company could go Bankrupt. That is reality.

No, I dont think model cement will work. I do not think any qlue will hold unless you can put some kind of splint across the crack ( prefferable on both sides) and bolt through it.
I would check a site like www.freecycle.org and see if someone is giving one away. (Freecycle is a place where you can give away items in good working order in stead of sending them to the landfill. It is a great source to find items with a lot of life left in them.)
Have fun

No glue that I know of will hold the weight of a person I'm afraid the chair is done sorry.
