The Latest from The Skunk Works

June5

I’ve recently found myself in need of an air compressor larger than the one I currently use. After a bit of poking around on my favorite marketplace (eBay), I ran across a manufacturer of compressors within easy driving distance (Dayton, OH). I had a 5HP engine sitting around and decided to put together a compressor.

Delta 1010 Repair

February19
delta1010-tI love my Delta 1010. It has given me several years of reliable service. One morning several years ago, I noticed the the VU meter on my Alesis 12R was staying partially lit. Turns out that all of the outputs on the Delta 1010 had noise in them and the audio that did come out was distorted. I thought it might be the end of the road for my 1010, but after a little looking I found that there had been problems with the capacitors on some models. I cracked the case on mine and much to my relief, I spied that one of the caps in the power supply line had swelled and was leaking some electrolyte. How can that be relief? It meant that the problem was probably right there and should be quite easy to fix. Read the rest of this entry »

February13

E2M1.5 ThumbnailIn the interest of full disclosure, it has been months since I got the E2M-1.5 running. The first thing I did was hook it up to the SMC Digital Pressure Switch to see how much vacuum I had.

One Behringer B2031, Fried

June15

B2031One of my B2031 studio monitors crapped out in spectacular fashion last night. In a pyrotechnic display reminiscent of an arc welder, an apparent failure of the power supply treated me to flashes of light, copious amounts of acrid smoke, tiny drippy bits of melted metal and an aural experience only available when large alternating currents pass through components undergoing transition from solid to gas.

Downside: It’s broke.

Upside: I get to take it apart, see what broke and fix it.

Brook Crompton Motor Repair

R8ZZ BearingThe bearing for the motor on the E2M1.5 vacuum pump came recently and I took a few minutes to put it on. Since it was missing when I bought the pump, I also fabricated a new cover for the cooling fan.

SMC ZSE40-T1-22L Digital Pressure Switch

February27

ZSE40eBay is my vice. At some point I knew I was going to need some sort of vacuum gauge better than the tiny scale on the bottom end of my suction-side HVAC gauge. I’d looked at your standard bourdon type gauge, but to get accuracy beyond 3% put me in the $50 price range. Then I came across a ZSE4 on eBay.

E2M1.5 Disassembly

February27

E2M1.5 - 01Out of the box, this pump gets the same treatment. With fingers crossed, I’m hoping to have better luck with this one. Good working order would be nice, but a complete complement of parts would do.
