I'll Just Be 5 Minutes

That phrase has got to be one of the biggest fibs in the English language, now that we no longer send cheques to each other in the post!

In this case the 5 minutes in question is the time it is alleged that a popular brand of rapid-set 2-part epoxy resin glue takes to set.

Not in my experience this week it doesn't. More like 5 hours, if at all!

Allow me to explain.

I usually fix resin parts together using a slow-set 'super glue' which gives you quite a few seconds adjustment time, but I have run out of that at the moment and I only have the standard stuff in the house.

The Super Barn castings are quite tricky to join together and you've got to position them very carefully so I thought it would be best to allow myself a little wriggle room and I elected to use epoxy resin instead.

Perhaps it is because the tubes are quite old - maybe as much as two years old - but it has been very slow to cure. In fact 24 hours on from being mixed the stuff left over on the pallet remains soft and tacky.

I wanted a glue that allowed me some adjustment time but what I definitely didn't need was one that allowed the parts to adjust themselves by the force of gravity whilst they set!

I had to leave it a whole day between gluing the doors on either end of the main body sides for them to be fixed firmly enough to be handled without moving - and during that time I had to return to them every so often to check they hadn't slipped out of place. (And they had.)

Trying to put the ends on was even worse!

Six hours after I'd joined them together, and with countless visits back to the workbench to fiddle with them, there was no sign of the joints curing into a firm hold, so I pulled them apart, cleaned up the parts and resorted to Super Glue.

Within minutes the basic carriage body was formed and I could cut out a basic floor to slip inside to help keep it in shape.

Epoxy resin?

Poxy resin more like...
