The roof looks absolutely great and it matches the main building as already guessed. Even though not looking like from that angle, it levels up with the other part?

Doing some insulation work at my home currently. The first floor is larger than the ground floor, giving the porch some roof. But the first floor had some feet cold portions. This should be removed by installing insulation underneath. Of course this is to be plastered afterwards. I basically...

The internet being mostly *********** and a retired craftsman rejecting additional payment. Ist this the past better times, people are talking about?

But even the dark side of the Sun will still be pretty hot.

Hej bctexas, as mentioned, no offense. Am really glad you started looking at these speciallity in those serial numbers. Coz without that inspiration I would not have gotten curious or started my research. Unfortunately everything Sun did, seems being a secret. Usually there would be a printing...

Wow! Never seen such a tester before. Great thing, perfekt condition. This is a wonderful example for an unit, manufactured prior they started with that code in the serial numbers. The round gauge indicates, it being older than the sixties testers with the rectangle gauges, to be seen in...

Inspired by this post, I started checking my own units, as well as taking dataplate screenshots of units being for sale in eBay and other platforms. Neither attempting to proove anybody wrong, nor having decoded the data plate. Made The following observation: The serial number prefix of a two...

Funny enough. I travelled the world, but did not manage heading sixty K southbound. But still having in mind...

Impressive, which stories returning to light during rebuilding that barn. Beside, my understanding of past times was, a) a person older than sixty years was considered really old and b) enterprises were managed by the older generation as long as they could handle it. So I feel surprised...

These blocks are typical for construction in Europe. At least in the northern part. Insulation properties were already mentioned. The classic red brick, we all know, is 240mm by 115mm and 71mm high. It weights about 3,9kg. So it will be three layers of four red bricks replacing one of these...

Great job! Looks like you'll be moving in in autumn. The window will fit perfectly. Will it be with dual layer glass?

Inductive pick up # 617-96363 is currently on auction at eBay. Not being interested in buying this, but I have exactly the same in my garage. Aquired in bulk with other stuff. Can anybody tell which machine this originates from? Thanks! Click for pic

Within the optical unit, between the tubes, there is a white phenolic block. On top it shows a screw and a small tube or some round metal thing. That's the IR-source. It will be heated up to a certain temperature, start glowing in result and therefore emitting IR in a certain frequency. Have...

Since it is only the trusses, there should not be too much force impacting. Regardless if it is wind, rain or snow.

The IR chip has two channels. Does it stupid things for HC and CO or ist only one side affected? The EPA 70 uses the same patent number. It basically has the same optical unit installed, but since solely going for CO, the second, reference, tube ist just a tube. Completely empty, without any...

EPA70, inside the optical unit. But there is a sticker on the outside as well. Stating patent number and a serial number. Sun aquired the right to manufacture a certain quantity of units, using this patent. Or they were supplied with a certain number of pre-manufactured optical units. How ever...
