Good idea or nuts?

FWIW, I keep a few Thermalite blocks around to build small hearths with as
required. Since Thermalite is soft, it is easy to cut holes and slots in to
hold work in place.

I have a few insulating firebricks - the type used to make lightweight
kilns - these are similarly easy to stack together and cut to shape if
need be and are good for 1400 degrees C.

What sort of temperature will Thermalite whithstand?
A few blocks came floating down the canal recently, I've just used
them as blocks to sit steel plates on for cutting, that sort of use
hadn't occured to me.

I doubt if they are going to withstand prolonged high temp - if I'm
not mistaken, they are a cement-based material rather than a ceramic,
and so are likely to de-nature somewhat if you heat them up too
much/too often.

I've used a cast iron BBQ stand for years. Take the top stuff off and use
good old-fashioned fireplace fire bricks. They come in useful sizes of 1' x
1' and 2' x 2' and form the sides, back and base.

The smaller ones are also very useful on the bench when silver soldering
smaller jobs as being about 1" or more thick little or no heat goes through
them.

Hi Roy

I'm definitely going on the Sunday to Guildford, let me know if you ar
too.

After my traumas with Centecs I managed to add a self-induced one wit
the nicest TS E-type I've ever seen. Gorgeous one on ebay this week.
was going to bid 1400, but a crisis at work meant I missed it. It wen
for 1220.00 :-(

One ray of sunshine: I picked up a clean base for my Amolco head, so
now have a simple, but pretty sturdy bench mill - anyone got any advic
for using these?

Cheers

Mat
