Hi All

I am selling Brass heater blocks (as pioneered by Nophead).

The brass is 18mm x 18mm by approx 9mm.

Threaded for M6 barrels
With a 5mm diameter hole for the resistor
With a 2.5mm recess (approx 4mm deep) for the standard thermistor

Block only is £6 + postage (58p for 2'nd class)

Block + resistor + 2 bootlace ferrules to connect the resistor to your wires £8 + postage (58p for 2'nd class) - I only have 4 of these currently available.

I can do a different hole for the thermistor on request (or even leave it out completely). You can also request a different diameter hole for your resistor if you already have one.

photo to follow shortly.

Please PM me if you wish to order one.

Cheers

Except I use aluminium because it is cheaper, lighter, more conductive and warms up faster (lower heat capacity). I don't know why everybody else uses brass, but you are in good company: Adrian, Brian, Wolfgang, et al.

I appreciate Aluminium is cheaper, but I have brass in stock from when I tooled up to make my own heater block.

Perhaps if there is a sustainable market for me to produce heater blocks then I may source some aluminium and give people a choice... but for now I need to recover my equipment and materials costs.

Also - brass looks niiice

What is the expansion difference between aluminium and brass? This may (or may not) be relevant if using a brass barrel and an aluminium block. Maybe the expansion is so small that the difference does not matter. In which case it would be better if brass expands more than aluminium - giving you a tighter fit = better heat transfer as the aluminium block heats up.

I was feeling somewhat uncomfortable with the pricepoint I chose, so I have changed my non-ebay prices to £6 for just the block and £8 for block+extras.

(as apposed to the original £8 and £10 I posted yesterday)

When I place it on ebay I may increase the price sligthly to make up for the listing charges and 10% sales price charges....

I'm sorry. I thought this was on another forum. I didn't realize that this is the For Sale forum.
