I understand it, I just can't lift it any more nor can most part time smiths. If your going to need another piece of equipment from HF to move it how handy is it? I have a 300# anvil, love working on it, but I can't move it from one new studio to another anymore. I need to hire rigger to do that and they charge a minimum $500 fee just to show up but I can get a day laborer for $50 and he can move everything I got except the 25# LG. So yes I understand mass but I also understand having to work out of a situation where you need to have lighter, more manageable equipment then a 300# anvil, 307# swage block, a 900# LG and Philip's question was not about "large" castings but "small" castings. Having used a nice light 75# malleable iron swage block that I could move and flip over on my own was nice just to bad I didn't own it. No pry bars, chain hoist, jacks or small boys needed.
