I was doing a favour project for a neighbor on his car. More specifically, my boss told me to do it. Looking for some help on a better clamping setup for this.
A .75" shaft is machined on both sides to be .55". It seems very simple except for the clamping.
First I wanted to hold it in the T-slot grooves but the cutter doesn't reach that low. I then used a pair of V blocks and tightened it down as hard as I could with toe clamps where the shaft on the toe was right near the bar. I had the two V blocks about 18" apart and would shuffle the clamps along the bar to reduce chatter. Seems like the V blocks shifted and the bar got mangled. It was working for a bit, but not very long.
Any suggestions on better setups or what I could do? I am thinking getting some keystock and fastening a key to the bottom of the V blocks. My boss suggests to see if there is a V block with a hole through the middle to fasten it to the T slots but I have not heard of such a thing.
We have only one big machining vice. I would use a pair if I could.
