Using toroid mounting bolt to secure PSU board?

mymindinside · 21st February 2010, 01:41 PM

Hi everyone,
im putting together an F2 clone and have a question about using the toroidal transformer's mounting bolt. The capacitor bank of my PSU is mounted to a metal sheet with clamps. this sheet has a hole in the centre. can i use the top part of the transformer's mounting bolt to hold this sheet in place? i will add an additional nut to the bolt to give some extra clearance between the top of the transformer and the bottom of the sheet. i am using a 1/2 in. bolt that is 5 in. long.
one problem i can think of is that there is a greater chance of causing a shorted turn. Assuming that there is enough clearance around the sheet to avoid this, is there any other reason not to do it?

cheers,

I followed up with deep searching and have abandoned this idea.
i will hold the plate down with bolts on the four corners.
this builder did something very similar, and people have advised him not to do it.

cheers,

You can securely stick a lot of components with contact adhesive, even transformers. I know it sounds nutty but it works fine. You just need the right glue and give it a couple of days to dry. Its a very handy technique for capacitor banks, as long as you aren't going to want to swap caps.
