Epoxy glue review.

Review on: Advanced Adhesives 3290 and the Loctite EA 9483 heat resistant epoxy .

You (all my thousands of followers:) probably remember my last week post about how to built a glue gun.

Today is a follow up post to review the two different glue that I used.

As I mention in the last post. I needed a high heat resistant epoxy glue to help me fixing  the wooden handle to the tang of my knife, using brass pin that run from side to side on the handle through the blade tang.

I started with the: Advanced Adhesives 3290. It offer heat resistance up to 200 degrees Celsius and a great deal of strength.

It is a two component glue, and I used the factory recommended mixing standard (Green) nozzle to mix it. Since it was my first time working with that glue, I first squeezed 4cm length of mixed glue  on peace of scrap wood. I let it cure as in the instruction and the glue set dry properly.

When dry and cure it is rather of-white in colour but, I was happy with that.

Next I was using it to fix my brass pin (see my last post for more details on that). I waited the recommended curing time, than I checked the result. the first thing I notice was that oxidization started on the brass pin. The glue wasn’t fully cure and was still wet. I left it for another two days  but it didn’t cure.

I scrap the pin that I been trying to glue into the knife handle, and start over with new brass taking great care to clean it properly before applying the glue (I used acetone). It didn’t work. the glue shows the same symptom as before.

I contact the manufacturer to see if my method of applying the glue was wrong. They suggest that the gun the I used didn’t dispense the glue’s two component exactly at 1:1 ratio, although they said that the glue will cure even if the ratio is not 1:1 and there is a degree of tolerant in the quantity of the two components.

In the photo below, the nails are levelled to each other, indicating that the dispensing rate was correct.

Epoxy glue review

I sent them the original brass pins and the wood that I been using. They say that they tried  gluing the pins to the wood and succeed with it.

I did try to be more scientific about it. I did mini experiment.

I used another glue, Loctite EA 9483.

Here some technical info about it:

Working time: 25 – 60 min.

Fixture time: 210 min.

Viscosity in Pa-s: 7

Tensile strength: 47 N/mm²

Peel strength: 1.5 N/mm

Service temperature range: -50°C – +150°C

Colour mix: ultra clear

The experiment

I use the two glues to glue the exact brass pin that I use on my knife. I spread four blobs of the glue (two for each glue) on piece of wood from the same wood I used for the knife handle. I then stick the pins, one on each type of glue. I use my wooden glue gun to apply the glue and in both cases I use a proprietary mixing nozzle. I left it for the recommended curing time and checked.

Epoxy glue review

 

The glue on the right is the Advanced Adhesives 3290 and the Loctite EA 9483 is on the left side.

On the right end side of the wood, you can see the greenish oxidization residue formed on the pin brass,  Also notice that the glue is crumbling where it touched the brass. The glue on the left seems to cure properly. The surface of the brass pin is very smooth, so it was easy to detached it from the glue, but you can see that the glue on the left is clear and nicely cure and the one on the right is not.

As you can see both glue work good in the blobs without the brass.

Conclusion:

In spit of the manufacturer’s comment, I still think the Advanced Adhesives 3290 didn’t’ do a good job and I will not use it again for that proposes. The Loctite EA 9483 did what I wonted it to do and although it less heat resistant, it still held its integrity after  the sanding process.

Skandika shower and toilet utility tent review

Two month ago my wife bought a tipi tent. We put down by the end of the field near the crick where we live. Now and then we spend the night in it. It got nice little wood burning stove, and very good mattresses, so it’s all very comfortable.

Problem is, one need to go to the toilet last thing before go to sleep. The obvious solution is good but only for man. So we bought from Amazon what look like very nice Skandika shower and toilet utility tent – Green/Grey, 1 Persons’. Its measures: 130x130x210cm, and weight 1.1kg.

The first problem with it was the flimsy short and literally useless pegs it came with.  The pegs barely stay in the ground and we had to replace them immediately. Also, the short metal inserts between two poles, wasn’t attached properly to the poles, and tends to part away from them.

We manage to put it right and equipped it with portable toilet seat. The women were very happy about it, but after the first night one of the tent pole snaps and the tent collapse.

We order new set of replacement poles from Amazon. They looked more reassuring this time, more robust built and heavier, and It did the trick. However, the next night another pole snap, and we replace it too. Third night the same but now two poles snap.

So it is not good product. I am bit surprise, because Skandika seems to be big tents manufacturer, and one is expecting it to be of a minimal standard.

Maybe the curve of the poles is too tight? And if that is the case they need to pre bend some of the metal inserts to help to take the tightness of the pole’s curve.

Adonit JOT script stylus review

Today review is about the Adonit JOT script pen stylus.

I have that pen for about one year now. I bought it for using as a pen for sketching and writing text in my iPad mini. I use various sketching Apps, but mainly with app name Noteshelf.

The stylus is one slick and cool looking pen. I read a lot of reviews about it, and largely it got good reviews.

It is: Fine point active stylus for iPad and iPhone, with 1.9mm tip. It made of aluminium, compatible with iOS devices with Bluetooth capability. It runs by one AAA battery.

My problem with it is:

It is not very accurate; it always starts the mark on the pad with offset, i.e. If you start a line or text, the actual mark will be at least 1.5 – 2mm off the intended spot, and it is near impossible to stop tracing line and continuo to do it, from the exact end of the line point.

As I mention, its slick and cool looking pen but because of it, you can barely see the on / off batten, and you can barely fill it. I understand the desire of the designer to keep it round and uncluttered device, but lack of clip handle or any other mean of prevent it from rolling over, made it ho so irritating.

Hope it help.

Dualit Coffee Grinder

My first review is going to be on the Dualit Coffee Grinder.

I bought it some three months ago, on-line from John Lewis. Prior to purchasing I did some research and decided to go for the Dualit machine. It was well recommended by other user it’s not looking that ugly and it wasn’t ridiculous expensive.

I will say from the start it does work well. Haaaaa, here come the but, there are few problem with it.

It seems as if only the young ones drinking freshly ground coffee. You can barely see the marking on the Dosing Control knob and because of that you can never be sure for the amount of coffee you are going to grind. Is it on the marking three or ten? Well you need to fetch your glasses but this is a deferent story.

The other problem which is more disturbing is that after two and a half month of grinding coffee, probably once every other day, a hairline crack appears on the Ground Container Lid.

I did contact John Lewis and they asked me to bring or to send the machine to the nearest JL branch. As it is the nearest branch to my place is two and a half hours by car or good few pounds to send by post. So we settle to send only the lid, so I guess I will grind one kilo of the good stuff and will send the lid.

And lastly, some friend of mine left in my house bag of coarsely ground coffee. It was to coarse for using in my espresso making machine so tried to give it a further grind in the Dualit, but the coarse coffee powder didn’t free fell in to the grinding burr and i ad to shake the machine to help it flow.

I wander what will happen with the broken lid? But I keep you up dated.
