I’m mak­ing my own loads for a rake of Hornby OTA tim­ber wag­ons from dried twigs. How do I dis­guise the glossy de­posits left by the PVA glue? Brian Warburton, by e-mail

Ge­orge says: A few years back, I treated half a dozen Hornby and Bachmann OTAS to log loads us­ing Hawthorn twigs that had been left in a warm room for a few months to dry out. I’d ini­tially thought of us­ing PVA to bond the twigs to­gether but, be­ing im­pa­tient, I plumped for cyanoacry­late glue in­stead. An odour­less for­mula was em­ployed, to avoid any stain­ing of the wagon’s paint­work and al­low a lit­tle time for ad­just­ments to be made be­fore the glue cured (about 30 sec­onds). The glue was ap­plied with a pin­point ap­pli­ca­tor tip and, as much as pos­si­ble, the glue was ap­plied to ar­eas that would not be vis­i­ble from the out­side. Some blobs of dried glue did show through, how­ever. Like PVA, the glue dries to a slightly glossy sheen that con­trasts with the nat­u­ral wood bark. A quick rem­edy was an all-over coat­ing with clear matt var­nish, which ren­dered the glue stains in­vis­i­ble.

Cyano glue of­fers a faster op­tion to bond­ing logs than PVA. A liq­uid ac­cel­er­ant speeds up the bond fur­ther, which is help­ful when us­ing slower dry­ing cyano, and al­lows for ad­just­ment.

Matt or satin var­nish will re­solve any prob­lems of shiny glue stains on the logs or wagon paint­work. Res­train­ing straps can be cut from elec­tri­cal in­su­la­tion tape.
