Ok. I found the way to do this:) So here are some photos with a little bit of explanation. 1. 3 pieces that will form a riser. Joris is making a hole for a port  2. Cutting the port  3. Glueing two pieces with the specil ceramic fibre glue.  4. Riser  5. Piece of ceramic blanket glued with vermiculite glue, will be placed beetween riser and port.  6. Here it is.    Riser is wrapped with ceramic blanket for stability.   And the space around the riser is filled with clay/vermiculite/fire cement mix.  |

morticcio: Can you please let me know who this supplier is? I'm interested in using them (reinforced) for a 5" system. Thanks.
Gavin, apologies for not responding sooner. The company is Ingram Industries, Dudley, West Midlands. Where in the UK are you?

Guys, if you can't find this stuff cheap, making one heat riser out of superwool and binder around a PVC tube shouldn't be too hard. Even if you want to vacuum form it, a little fridge pump, and tapped plastic should do the trick. Myself, i think i'll stay in the refractory tubing surounded by rockwool or vermiculite. May be not as lightweight, nor as fancy. It has thermal inertia, while superwool risers have less. But it's cheap! satamax, where do you get refractory tubing cheap? I must be looking using the wrong words because everything i find is really expensive! |

Hey guys and Satamax. You told you use this system: www.landinispa.com/landini/user.php?nid=138but as far as i know those tubes are max 500C resistant... if we want to use them for risers than the high temp will kill them... they will crack and the rest of the clay tubes i have seen here... do you do something like precut? i think they will not las long... whta do you say guys? |

Robert,
It's worth to try those clay tubes. When you want to avoid cracks precut the tube lengthwise, one side only. The cut could be filled with superwool or you can rely on the insulation around the tube to make it airtight.

Hi Robert. In their old catalog, they had the same inner tubes, rated for more than 500C°. At least the landini tubes i have used had "chamotte" in them. Anyway, as Peter explained, i tightly pack vermiculite around and i don't worry about cracking. They do crack, but who cares  |

They do crack, but who cares I do  Since i will be building some setups for clients than i want to be sure that it will last long:) |

Once theses have cracked, they won't move anymore.

Robert, How about a 'double skinned' riser like the one Bernard is making?  |
