drill bit responses / plate lifters

[Graeme Harvey]

Hello Greg,

I use an "I" beam slung across part of my workspace with support from 4" x
4" posts and part of the wall framing. An engineer friend calculated the
required dimensions etc. I hang an endless chain hoist from it and can
easily lift up to a ton. The endless chain system allows very fine control
by just one operator.

In fact I lifted a frame out of a  7' grand yesterday on my own, wheeled the
case away then lowered it onto a work trolley to prep for refinishing.
I usually like some one else to assist in replacement as it is a little
easier to guide it in, though I put guide dowells in to help.
The beam is 200 mm though I could have used a 150 mm but the guy who cut it
for me let me have the heavier one cheap to avoid buying in extra 150 mm
stock.

I couldn't operate without it and wonder how I used to get on before I had
it.

Hope this helps,
 Graeme Harvey
