AAR B Truck Wiper Blocks: O Scale


These wiper blocks were designed for the Central Locomotive Workshop AAR B truck but will find many other uses. Ships with 4 blocks made from a nylon resin. This resin taps and drills, sands, cuts and glues like a dream.
Wipers are not included but we used .003 Hard Phosphor Bronze from Clover House. You can check their full Website here.


  • Many of our parts come with supports still attached, and will need to be carefully cut. We always recommend a good sprue cutter for this. Some minor sanding may be required. Parts that have had their supports removed may have some small bumps where the supports were removed that will need to be sanded/filed off for a better fit.
    ACC glue works well for all our resin parts.
    Parts take paint well after priming. We recommend Mr. Primer Surfacer 1000, but any good thin primer will work.
    All parts come unpainted.
