Cheap chair repair

[OldWood]

My son has just got his first house and has got a re-cycled set of cheap pine Windsor (?) style side chairs. These will do him fine as a starter but some of the joints are a bit slack.

I don't really want to go to the extent of dismantling and re-gluing, and wondered if the injectable Gorilla PU glue from Axminster is a good repair option.

Thanks

Had as similar problem and used some titebond in a syringe. Worked well.

Probably better not to be tempted to use a low viscosity super glue OW. It'd wick into the joints very nicely, but won't cure if there are gaps of over a small fraction of a mm.

The cured polymer is very brittle too, not really the deal for that kind of joint unless the fit is so tight that there's no possibility of movement....

Superglue would be unsuitable - it's PU glue that I'm thinking of and Axi do this

I've edited this to ask Hamburglar what Titebond he used.

Or maybe this, which is designed specifically for the task and comes complete with a needle applicator.

I bought some of this a while back for a repair, but never used it, so sadly can't comment on effectiveness.

A few well placed screws with plugs to conceal can make quite a difference.Some of the screw pilot holes can also be injected with glue

 

[OldWood]

That thought had crossed my mind too.

These are cheap pine chairs so a line of brass, or brass looking, screw heads along the back of the seat to tightening up the back rest are unlikely to be of any significance visually; plus as you say piloting and injecting glue before the screw, can only improve things further.

Have used "Chair Doctor" many times in the past with great success. Drill a small hole, the size of the syringe, into the mortice and squirt the glue in. It will swell the tenon and tighten the joint.

Does anybody know what type the chair doctor glue might be? If it foams it may be a low viscosity polyurethane.

I guess you could probably do something similar with a low viscosity epoxy resin, although i'd be cautious about using a laminating resin (it might be OK) as if my memory isn't shot they may exude a thin layer of wax to the outer surface to stop the air from inhibiting curing of the surface layer and leaving it tacky.

There's quite a bit of information on the Lee Valley site http://www.leevalley.com/wood/page.aspx ... 10&p=30261

Cheers :wink:

Chair Doctor has the consistency of milk. Avoid using a polyuethane glue as I found through experience, when it "foams" it expands and pushes the joint apart.

Took a look. There's nothing where they advertise the product, but one or two antique repair sites (who seem to reckon it's not suitable for antiques on grounds that you can't disassemble it) seem to think it's some sort of PVA based stuff...
