New toys have arrived!

My order from Harbor Freight just arrived: digital calipers, a digital scale, and a digital angle gauge.

I did a quick check on a couple of bikes here with the scale and angle gauge and got some surprising results. My '73 Bottecchia Gran Turismo came in a bit lighter than I thought: 24.6-lbs with pedals and pump. But what really surpirsed me are the frame angles: seat tube 73.5 degrees, head tube 74 degrees. Those are slightly steeper than I expected (I would have though 73/73 parallel) My Bottecchia is as yet incomplete so I can't get a weight but it has the following: seat tube 72.5 degrees, head tube 71.5 degrees. Those numbers are in line with what I would expect for a Special.

I need to practice a bit with the angle gauge now to make sure I'm getting good measurements and get all the bikes weighed.

New toys are always fun. Have you had a chance to utilize the calipers or are you just anticipating a time when you'll have to identify some mystery tubing?

Both Bott's that I measured are 23". I also have a 25" Special frame that I'll be measuring and a 22" Professional. I don't have a headset in the Professional right now though so I can't do that one yet.

No, I had calipers already but they are the kind that you have to line up the little hash marks and my old eyes just can't handle that anymore so I got the digital model with the Readers' Digest style large type display. Haven't used them yet.
