Has anyone used electronic pocket scales for VTF?

I like to retract my statement about the VFT at various heights. I use a homemade 14 inch carbon fiber tonearm (measuring from pivot to stylus tip) with Shure type III cartridge. My scale didn't detect the VTF changes when I varied the scale's altitude due to my tonearm high compliancy. The Shure cartridge is relatively forgiving on VTF. I use the scale to ensure the VTF within manufacture's limits then fine tune with listening test. I enjoy inexpesive vintage sound.

14" DIY carbon fiber tonearm? Sounds very cool. Have you posted any pics?

I substituted the steel arm tube from an Audio Technica broadcast tonearm with a graphite golf driver shaft. Note the lead strip covering the vertical movement pivot bearings, it acts as a damping device. The anti skating string device works well also.

Wow, very resourceful. I'm not sure I understand the bearing concept of the new arm. Is it suspended? Resting on the lead(?) button beneath the arm tube? Or...?

It is suspended by the fishing string which stablelizes the azimuth like in the Well Tempered arm. The ball bearing is glued to the armtube and fitted into the hole of the cylinder (button). This arm employes the same principle as the Shroder Reference tonearm. At first I was impressed with the smooth sound of the "new" arm. When I modified the gimball bearing arm with the graphite arm tube, I really enjoy the sharper image/focus of the gimaball bearing arm design. I also loaded the arm tube with wood chips and silicone jell to damp the long arm tube similar to the fine sands in the Well Temper arm or silicone fluid in other arms.
