I've got an old TEK LV transformer that I'd like to use as a power transformer for a project. It's large and heavy, so in an effort to lower the center of gravity of the finished unit, can I cut a square hole into the top plate and secure the transformer to the aluminum chassis with laminations resting against the top plate or is this a bad idea?
That's what I did with my PT. Cut a hole and let it drop through. It's not sitting exactly on the laminations, though. There is a nut on the end of the bolt that goes through the lams. I did not remove that nut before I mounted the transformer.
Aluminum chassis might be a good idea - easier to cut, and no magnetic interaction with the transformer.

If you bolt the transformer top and bottom you are creating a single shorted turn through the bolt and the chassis !
There was a warning against doing this when I recieved my transformer......
Re: Re: can trafo laminations rest on chassis?
Many transformers have a insulating shoulder washer on one end of the long bolt to prevent that when necessary. But I have also seen original transformers that do not. So I guess it depends on how the transformer is constructed.
edit: This may also depend on the material used for the bolt. Whether it is steel or non-magnetic (300 series) stainless steel.
