Re: Current DIY projects you are working on ... or planning on.

I have a little tech question in my day today.

I'm trying to fix a big window fan.
The shaft for the switch (the part inside the knob) broke. I couldn't just replace that part so I had to buy a whole new motor assembly. Annoying.

Then I went to remove the fan blades, in order to replace the motor assembly, and the set screw that holds the fan blade on is rusted and will not budge.
I tried Liquid Wrench. And I tapped it. Any other tips?

It's not easy to apply a ton of pressure on this little hex key. And I'm not sure brute force is the best way to go here.

I guess next time I purchase a replacement part I better first check that the old one can be removed. Argh.

T.P.
yes you can generally replace switches


letting a penetrating oil soak and applying light †orque for prolonged duration is better than †oo much all at once

strategic application of heat can loosen many things but also cause great damage

careful; it is not difficult to unbalance a fan by distorting a blade

a jewelers oxy acetylene torch can localize head and make small metal parts expand

I should have taken more pictures, but as soon as the back panel was wired up it went into the rack for testing and hasn't come out.
Looks awesome! Where did you get the enclosure? I'm looking for something to rack some McCurdy preamps in.

Thanks!
Got this enclosure from Penn-Elcom. Great quality, and prices are reasonable for low quantity orders.
Shipping was a little rough, but I'm in Canada. If you are in/near England or New Jersey, shouldn't be an issue.

May be easier to deal with them as a business, but I think Penn-Elcom US have an eBay store as well.

I'm also racking up some funky LOMO mic pres which should be interesting!

DIY and die anyway.

Awesome - I am in Nova Scotia - I will check them out though. Those LOMO's look wild - are those transistors just glued onto the PCB upside down? Also are those Beyer input transformers on the LPBs?

There is a company near where I live called Protocase that does custom enclosures, but they seem to be prohibitively expensive for this kind of thing.

Right on! I'm in Ottawa right now.

They are just upside down germanium NPNs. Right now I have some Tamura iron on the input and some Hawk made iron (essentially J123s replacement) on the output.

Good eye with the LPB cards! They are Beyers in the preamp cards(surprisingly, they are original), not sure what the line output transformers are.
I'm a big fan of the Beyers from having used them in another 4 channel preamp build.

I had never heard of Protocase! Hammond have also been easy enough to deal with and they are here in Ontario, but for some reason don't do rack enclosures.
Who knows why...
