Glyn44 Posted January 3, 2018 Share Posted January 3, 2018 i have decided to try Robart pin hinges for the first time. I have reached the point of glueing them in. Just wondering if anyone has a trick for getting the rather viscous epoxy well down into the holes, especially the small 1/8” sizes, without making a mess all over my new shiny covering? I will already be masking around the hole, but am unsure how to get deep penetration down rather than just the top couple of mm. Or should I use a thinner adhesive? Thanks as always Glyn.

Jon H Posted January 3, 2018 Share Posted January 3, 2018 i use a small stick to help get it in the hole, then coat the hinge about half way up its length and then pop it in. Dont forget to add a dob of oil or grease to the hinge to prevent epoxy getting in there. Any sticky finger prints can be cleaned off with meths on a rag before the epoxy dries Quote Link to comment Share on other sites More sharing options...

Peter Miller Posted January 3, 2018 Share Posted January 3, 2018 I just use aliphatic wood glue. Never had one pull ou and it give you time toget things right Quote Link to comment Share on other sites More sharing options...
Nigel R Posted January 3, 2018 Share Posted January 3, 2018 I like alliphatic glue for hinges, too. It cleans up easily with damp kitchen roll. Never had a failure yet. Caveat is, I've never used Robart style, always flat polyprops or flat pinned types. Edited By Nigel R on 03/01/2018 09:43:05 Quote Link to comment Share on other sites More sharing options...
Bob Cotsford Posted January 3, 2018 Share Posted January 3, 2018 I keep offcuts from pushrods for this sort of job, they're 2mm so it's easy to poke the glue down into the hole. I'd be lost without a few 3-4" pushrod lengths floating around the bench. Once the hinges are in clean up with some methylated spirit on kitchen towel before removing the tape..

Engine Doctor Posted January 3, 2018 Share Posted January 3, 2018 plus 1 for Gorilla glue for hinges. A tiny drop squeezed into the hole expands and grips the pin very well. If you use epoxy make sure its 30 min or longer to give you time to clean up any excess. Quote Link to comment Share on other sites More sharing options...
Robert Welford Posted January 3, 2018 Share Posted January 3, 2018 To reduce the viscosity of the epoxy so it penetrates the hole more easily heat it with a heat gun. Note: it will reduce the working time by doing this - whether it is 5 minute, or a longer setting epoxy.

Glyn44 Posted January 3, 2018 Author Share Posted January 3, 2018 Ok thanks for all the info. Going to try epoxy poking, and aliphatic, see which I get on with. I haven’t got any gorilla, had some but it went hard in the bottle after a couple of years! I don’t want to buy more as I wouldn’t use it very often. Thanks again.

Ron Gray Posted January 3, 2018 Share Posted January 3, 2018 You could always thin the epoxy with denatured alcohol. Quote Link to comment Share on other sites More sharing options...
Merco 61 Posted January 7, 2018 Share Posted January 7, 2018 Another way: find a piece of tubing to fit the hole(or slot) Then suck sufficient adhesive up into the tube,insert and blow.Flatten tube if for a slot. Quote Link to comment Share on other sites More sharing options...

I like that. You could probably use a lightly oiled piece of piano wire to make a simple syringe. For barbed 'hinge point' type hinges, PVA/Titebond is perfectly fine. Easy clean-up means you can ensure the glue comes right up to the hinge's knuckle, without danger of it locking up the hinge. Quote Link to comment Share on other sites More sharing options...
cymaz Posted January 7, 2018 Share Posted January 7, 2018 If you haven't drilled the holes yet, and you will use the Robart pin hinges again, invest in the drill jig. Its a great way of getting the holes right in the middle of the work piece. (I have drill bits that I keep only for the jig in a little box along with the tool) I also bevel the hole edges ever so slightly so as to ease the knuckle further into the holes for a tighter fit and less of a hinge gap. I coat the knuckle with petroleum jelly and zap it with hot air. This will stop any glue gumming up the hinge. I put both sides in at once...not one side at a time after the epoxy has gone off. Doing the latter makes adjusting a pin that is out of square impossible Quote Link to comment Share on other sites More sharing options...

Glyn44 Posted January 7, 2018 Author Share Posted January 7, 2018 Funny that you have fired up this thread now, as only today have started glueing tin pin hinges. From your advice I decided to use titebond. I used a very small aperture squeezy bottle, plus a smearing onto the hinge, stopping well short of the hinge joint. This I had also greased, as advised. Against Cymaz’s advice I did one side at a time, but will heed that tip tomorrow when I continue. As far as I can tell, it’s been a success, won’t know til morning when I can give them a good tug. Thanks again all, appreciated. Quote Link to comment Share on other sites More sharing options...
