E2M1.5 Rebuild
February29
I ordered a rebuild kit a few days ago from Capitol Vacuum and forthwith it appeared on my doorstep. I also ordered a gallon of grade 19 vacuum pump oil – it is a must-have.

In the mailbag today from LDS Vacuum, we have parts to connect the wayward vacuum pump to the real world. On the left we have a stainless NW16 to 1/4″ NPT adaptor. On the right we have a NW10/NW16 centering ring. Read on for more info.

eBay 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.

Out 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.

My last foray into eBay-acquired vacuum technology yielded disappointment. I decided to try again with a model still in production – the Edwards E2M1.5.

I picked this up from eBay. She’s short on the motor starting capacitor. Hopefully after finding a suitable replacement, she’ll clean up and be ready to suck. This model is supposed to do 45L/min and pull an ultimate vacuum of 0.09 Torr.
It is of British design powered by a motor of the same origin carrying the suitably British name of “Brook Crompton.” I’ll post pictures of disassembly and cleaning as soon as I get around to it.

I had intended this blog to be just about badly designed items, but I’d also like to share the odd projects I get into whether they be repairs, refurbs, or just plain neat stuff.
