A matter off what glue to use ?

[monica]

hi guys call on your expertise on what glue should i be using as up to date , have been using the revell blue/yellow glue, and some times super glue, which takes time to cure,

and on the bigger kits , is there a better type that set a bit quieter, as i have herd about plastic cement and all other types of glues , ?

any help always appreciated

Morning Monica it is here any way.

I use both Mr Cement S and Tamiya Thin Cement.

They are rapid glues perhaps a better description is a solvent. They soften the plastic allowing the two sides to weld together without a glue in the joint.

They have the advantage over Revell and Humbrol poly cement as they work so quickly. The great advantage is that they are so thin.

Place say the two wing halves together in dry form taping or clamping as necessary.Then using the Tamiya or Mr Cement with the brush in the solvent brush around the joint carefully. The solvent being thin will wick into the joint.

I mostly tack at various points. Wait a minute or two then tack between continuing until the whole thing is welded together. I use fingers to hold the pieces at each tack and wait only seconds before it has enough hold on the joint.

Some pressure the joint to squeeze out a little of the plastic and trim after the joint has fully cured. Not my way but we all have our techniques learnt or by accident.

Make sure at the tacks you do not flood the joint it will quickly wick along the joint

and glue the holding tape to the plastic. Likewise make sure fingers are well away from the solvent as finger prints etched into a model are not pretty and cause additional work.

If after joining there is a joint mark or a little filling is required I use Mr Surfacer 500. This is brushed on to the joint. This dries rapidly. File or abrade down and reapply until the joint is perfect. The great advantage is that Mr Śurfacer filler is about the same hardness as the plastic which enables the edges to be feathered into the plastic at the edges without crumbling away.

personally i never ever use the stuff that comes in a tube, just cant get on with it, too thick and stringy

if i use a poly glue i use a liquid one but probably 95% of my glueing is with cryo 'super glue' but always the thick not the thin which is too runny

if it dosnt set quick enough for you, you can get an accelerant like Zap Kicker, goes off in seconds

a lot of people dont like superglue cos they say its too brittle, etc but ive never had a problem

One thing I should have mentioned. if a really strong joint is required where perhaps the model rests on a near pin point joint Humbrol or Revell poly will provide a better joint.

With all these solvents the joint is fusing the plastic not glueing as such. Although the joint is not as strong as the surrounding plastic providing the joint has been well executed it will be as strong as you will get. It is a weld in the same way that steel is welded together.

I would second the use of Mr S Cement brilliant stuff which I use 95% of the time.

Hi Barry,

You might find it useful to read through this thread:

http://www.scale-models.co.uk/threads/back-to-basics.2298/

Laurie has put the glue issue together concisely and I think the thing to remember at the end of the day is that different glues have different properties, which makes them suitable for different applications. I always have tube, liquid poly and the Revel squeeze bottle available on the desk.

I use mostly the liquid type that you apply with a fine paint brush. Tamiya extra thin is good, Mr Cement is good. Even the one from Humbrol is good. The thing is practice the technique of using it with out finger printing the plastic at the same time! The link that Richard posted is well worth a read.

hi guys thank you all very much for the help,yes did read Richard post as well as what Laurie said i can see the use in both types and you can use one with the other if needed as do spot holds

and then if it needs to be filled use the other one, over the top to fill or use just a filler,as with the Revel squeeze bottle found i had to tape or peg and leave sit for a long time, but with fiddly things

that need to be moved about ,well the revel would be better to give more time, just with 1.35 over 1.72 can really see the need to hold it in place quickly , so the down side is to really have some

off both or all 3 on your work bench,ta again all
