Finally finished an HCCT meter that I have been working on for quite some time - converting a 0-50 Amp Weston 156 to a 0-2 Amp Meter.
Thank you Bob Cascisa and John Regan for all of your help. With the posted instructions and parts support it was very easy to do. It works well and itís very accurate.
Now I just need to mount it on the HCCT and build a box to hold the coil. I'm looking at incorporating Model T engine straps to mount it to using the twist of the straps to form a carrying handle. I will post the completed HCCT soon as soon as its done.
That's one beautiful Weston. The original HCCT meters were not nickel plated like yours is. That will make a HCCT that's almost too beautiful to use. Great job !!!
Do you have to use a 156 or can a 151 like this one be converted to use as well?
Thanks Bob. Unfortunately as you know, I dropped the face plate when I was putting the data plate back on. You can just barely see the crack in the narrow area just right of the glass. I ground the back side and repaired with JB weld. The crack is still noticeable but I liked the nickel plated face and wanted to save it.
Ed, Bob will have to answer your question as I'm not sure. I would think that the inside would be similar. I this correct Bob?
Ed, Keep an eye out on ebay. I was able to find this one for $41.00 and the inside was still like new. The outside was in good enough shape to lightly sand and repaint. It had a broken stud in the rear but they get shortened to use on a HCCT anyway.
The Weston Model 151 is a slightly larger version of the Model 156. It can be converted. The 151 is about 8.75" in diameter and the 156 is about 6.25" in diameter. Most any brand (GE, Westinghouse, Weston, etc.) of iron vane type AC meter can be converted to a HCCT meter. If you are not sure about the meter you have, send me some photos of the inside and back of the meter and I will let you know if it is a good candidate for conversion.
