Although I had fitted the handrail knobs to the boiler and smokebox earlier last week, I hadn’t added those on the resin firebox. This was for no other reason than the superglue was upstairs in the fridge and I thought it easier to crack on with something else and bring the superglue down later.<\/p>\n\n\n\n

When I did subsequently fit the remaining knobs in place, those on one side were fine but for some reason both on the other side didn’t seat properly and the glue set as I was trying to push them home. I tried pushing them in with pliers and gently tapping them but I was very concerned that the resin firebox might crack if I was too vigorous. They didn’t stick out by much but I wasn’t happy having put so much effort in with re-seating the chimney etc. It was during commode time (a term picked up from an american machinist who I watch on Youtube) that an idea came to me.<\/p>\n\n\n\n

This morning in between making the end caps for the handrails I plucked up the courage to give it a go. I got a short offcut of the 0.8mm piano wire that I have made the handrails from and put a small bend on one end gripping the wire in a pin vice just in front of the bend.<\/p>\n\n\n\n

I popped the bent end through the hole in the first offending handrail knob. I chose the one that was furthest in, to try the proposed solution on. Then I connected the negative terminal of my RSU to the piano wire which protruded from the handle end of the pin vice. A quick touch with the probe and a slight twist and the knob thankfully popped free without issue. Buoyed by this success, I repeated the same on the second offending knob and I had barely touched it before it popped out.<\/p>\n\n\n\n

As a precaution because I was heating superglue\/resin I had the extractor fan running at the side of my bench just in case any fumes were created. I was probably being over cautious as the glue just seemed to slightly soften rather than melt.<\/p>\n\n\n\n

Then it was a simple job to re-drill the holes making sure that the knobs were a loose sliding fit before attempting to apply more glue. It was at this point that I found out why one of them wouldn’t seat properly. There was a slight rim around the shank on one which prevented it from seating flush. It wasn’t really visible but when I ran my nail across it I could feel the ridge. To save time I swapped it for another one from the stores and both were fitted properly.<\/p>\n","protected":false},"excerpt":{"rendered":"
