Going to be working on a cherry library, and doing everything possible to keep nail holes to a minimum.

Looking into hot melt guns. Any suggestions?

What are you wanting to use the glue gun for? I would not recommend hot glue for structural joints. If you are wanting to use hot glue to fill nail holes than there are other methods that will work better.

I will probably get slammed by the hot melt glue lovers, but my advice is to avoid using hot melt glue for any permanent project. It has its place in arts and crafts projects and for temporarily fastening pieces together, but the structural strength is very poor.

How about standard Titebond and using a pin nailer, if you must,to hold things in place while the glue cures. Pin nailer holes are almost invisible.

Hah! One minute slower on the draw than WoodNSawdust’s comment. We now have two no votes for hot melt glue.

I had another thought on your question that might be more helpful than the two “don’t” responses you have so far.

Can you show us the plans or an example of your project? You might get better ideas on how to design the joinery and assembly to avoid any sort of mechanical fasteners.

I’m guessing that you are looking at a method for attaching trim pieces without having to deal with nail holes? As long as the piece will not see overly hot temperatures (above 250F), and you aren’t using it for a structural application, there isn’t any reason not to use it. However, all glue sticks are not the same – some have a low bond strength, some are considered permanent – so choose the correct one for your application. You can visit some of the glue stick manufacturer sites to get a list of advantages/disadvantages and what specific glue is applicable for what you are trying to do.

Cheers,
Brad

PS: According to Gluefast: ”hot glue is as permanent as epoxy glue and it is suitable in applications where epoxy is not. Consequently, it is important to note that hot melt adhesives should not be used to glue something that you may want to remove later on. ”.

You have no clamp time with hot melt glues unless it is a hide glue.

While conducting some research I found an article from Glue Machinery – that the standard diameter of most glue sticks is 7/16’’, do most guns support this?

I would hate to purchase a gun that needs customized size sticks that I can only buy from limited stores.

For the people who are opposed to this idea, one of my colleagues suggested a micro-pinner. Thoughts?

I’ve used hot melt on trim before and it worked just fine. If you don’t want to buy a headless pin gun then go for it. You could buy an expensive DeWalt or just go to Michaels or A.C. Moore or another craft store and get one for a couple of bucks. Doesn’t make you any less of a woodworker in my opinion.

For what part of your “cherry library” are you thinking of using the hot glue?

Hot melt will probably fail eventually.
Use regular wood glue and headless pinner.

Hot melt is great as a temporary bond while regular wood glues or epoxies cure. CA can also be useful. Think of both as clamps, not an end game.

My glue guns are cheapies that take standard sticks. If they fail, I’ll just buy another. This is not a tool where paralysis by analysis is warranted…

Nice phrasing. Might have to borrow that one.

I use my glue gun once in a while; mostly for crafty stuff or temporary solutions.

If you do get one, please look for a cordless model. Mine heats up on a charging stand. You then remove it from the stand and it stays hot for quite a while. Very convenient.

Have your say...
