Father, you’re already missed. He passed away when my daughter is only months old. He used to work as a welder when he was still with us. Now, that he passed away, his job is transferred to my brother. I wonder if they are using bar clamps with that kind of job. I believe this tool could help them make their work more easily and accurate. Anyhow, sorry for being emotional, I just missed my father and wish he is still with us but this is impossible already. So just allow me for being sentimental, heheh.
