So I have seen several examples of cabs in a bezel set onto textured plate. I assume at some point the bezel was soldered to the textured plate. So everything I have seen and been told is solder does not fill gaps and the joint has to be tight (light tight) to get a good solder joint. With the examples I have seen here it seems the texture was applied first then bezel soldered on and not textured after soldering.
So how do you deal with the gaps where there are indentations into the plate from the texturing? Am I taking the solder joint instructions to literally?
thanks, Steven

Based on his creations, brotherbill frequently solders bezels down on textured backplate. Do you have any suggestions, Bill? |

I dislike textured backplates for just this reason. I hope brotherbill will divulge some of his secrets! |

From my experience, solder will fill the gaps created by texturing of the backplate. Occasionally I discover spots where the solder did not fill the gap and I re-solder a second time.
Texturing will distort the sheet and the real challenge is to get the backplate flat after texturing and before soldering. A rolling mill texture will only mildly warp the sheet but a hammered texture makes it really difficult to flatten your sheet. Multiple anneals may be required. You can only hammer on one side, the textured side (with a rawhide hammer). Never put the textured side face down on your bench block while hammering or you will lose the texture.
So to sum it up, the gaps caused by the indentations are not an issue. Returning the sheet to a flat state after texturing can be the headache.

Hmmm... I’ve done it. Not a problem. Just go ahead.
A friend was trying to solder several pieces together. There was a triangular gap. I think we used about 25 solder chips to mostly close that gap. The two piece bezel-to-backplate has never been a problem. I suppose a heavily textured backplate might give trouble. Good luck.

An easier alternative for texturing the backplate is to roughen the surface with a 1mm(.040") diamond ball burr after soldering the bezel to the backplate. Example  |

This is what I do for texture on occasion, being rolling mill-less.  |

you can also sand down the area where your bezel will be

Not a great picture but you may be able to see the gaps on the lower edge of the bezel. These are totally acceptable in my book and the flowing solder will easily fill them.  |

Good to know. I have been avoiding textured surface for that reason. Now I will give it a go. Thanks again, Steven

It does not always turn out perfect the first time, like below. But it is nothing that a small piece of solder won't fix the second time.  |
