Repairing cracked Bakelite.
The black Bakelite component in the photos is the base of Philips 930a 1931 radio. It had an open crack from one side across a corner over to an adjacent side without actually separating it into two parts. I thoroughly washed and rinsed the base to ensure that there was no contamination or dust within the crack, applied thin superglue to the inside of the crack and clamped it up. After an hour or so I used lengths of threaded rod (bolts with heads cut off) and Araldite to reinforce across the cracks in selected corners of the base having first keyed and degreased the areas. This was done in three places, each being done separately time-wise to enable the base to be appropriately tilted such that the reinforcing rod and Araldite lay tight in the corners during the curing process. Whenever I effect a repair using Araldite I use this metal reinforcement procedure if the application allows it. I recently repaired some freezer draws using it.
