interesting David. Tamboura is my all time fav and I have tons of it, never had a problem. Could it be a bad batch?

I love the color! I always rout in 2 passes with any of the Volcanics and the Staron Tempest I usually go 3 passes.
Do you have problems with anything else? Is your bearing tight on your router?? I could see where a bad bearing, plus a not so sharp bit could pull chunks.
As for the deck particulate... are you saying you can feel all the chunks as a texture?
I would bet, if you make 2-3 passes.. you will get a better outcome??? If not... call your REP... |

Tambora also one of my favorites. Haven't noticed any of the problems you discribe.

If he's having the issue on the deck and in the cove then it's probably not a router issue unless I'm reading it incorrectly. Sounds like the binding agent isn't sticking to the particulates for some reason? |

Do you have any photos?
With out seeing it sounds like dull bits and over heating when polishing. |

This sounds like a real problem. Before installing, I would contact HI-MACS cause this could be a warranty issue.
Would it be possible to post some pictures of the problem areas? |

There is something seriously wrong here. You should NOT be hasving issues with particulates coming out of the material because of routing. Definately check with the manufacturer. IMO, a dull router bit should not even pull a particulate. Burn it or try to melt the entire material, but not pull particulates. |

Bill.... guess you didn't work with the first runs of Samsung Tempest CoffeeBean. Pits. holes, chunks, sanding the edge profile just produced gummed up paper... real fun stuff it was!!! |

Kelsey,
That's my point. LG realised there was a problem with the material and changed. It is not like that anymore, correct?
I believe there is a matrix problem when the particulates are not married into the carrier matrix. |

Exact same thing is happening to me with LG Sugar Maple (see Layout help thread)! Brand new cove bit, 2 passes. Same with the edge- small partial ogee with three passes=same results. Will post pics today |

Will post pics today Darren, I did a sugar maple job as soon as the sheets came out. No problem at all, just the smell was a little bad. The only way I know to tear chunks out, too fast and too much removal, dull bit, or bad vibration problem caused by a bad router bearing . |

Here are the pictures. I could not get the tearout on the cove to show on camera, but if anything it is even more pitted than the edge. Speaking of the edge, I didnt go too crazy with the sanding, as I am thinking I will skim coat it with adhesive to fill in the pits, but will wait untill I get some ideas why this happened first     Every edge and cove has pits and the ocasional big chunk (particulate?)missing. Even the edges where I did not router has pits, the surface only has a couple. (I'm a countertop fabricator, not a cleaner-no coments on the dust reidue on the island!) |

I ran into something like that with Horse Chestnut, there was pits.. not that bad. However, I always router in 2 passes... my 2nd pass taking a very small amount, which takes away any pits, tear out ect. After the 2nd pass eliminated any voids, I discovered my 1st cut tore material out creating voids. I have learned a 2nd pass eliminates 50%+ of sanding whether it is on wood or SS. I really think this 40%+ recycled material needs special attention!
My guess is your machining is pulling material out, instaed of voids being in the material. I bet you might have the same issue with Staron Tempest , I had unavoidable voids in CoffeeBean and Milestone.
Sometimes you have to fill with a little adhesive.
My question is, I'm not sure why this is installed in a house, when the edges look like that?
Darren, David, what part of the country you guys in? I'm in Kentucky and get my sheets from Columbia, Tn warehouse |

Not that it should matter, but that doesn't look like Hi Macs Tambora. Too bad it is installed in the house already. I would have siggested running your router backward to take off just a smidge.

I'm in eastern Canada and the sheets either come from in stock Toronto or Chicago.
The reason I installed with the edges like that is because the homeowner removed his own counter and upper cabinets on Friday, the new island cabinet was installed on Saturday and I installed the countertop on Monday -two weeks late after waiting for the material to arrive "in stock" from Toronto (of course via Chicago), and delayed in shipping by the frieght company. I worked a 45 hour week this past weekend, getting this job ready. If I could have delayed the install, believe me I would have. To make a long story short, it had to be installed and the customer was made aware of the edges not being fully sanded before the install.
I do appreciate any tips to fix this and prevent it from happening again
Anyways, would a skim coat of adhesive work? I have set it up with the customer to go back and they will not be home, so I could possibly re-router with a vac attachment |

Yes a skim coat will work, you just have a lot of holes to fill. Only thing about routering in a house, is the dust and walls where your router will not reach. You might try it on a accessible edge though... just remove a hair, and then go back with your ogee??
Back in the shop, try what I said with the scrap. I really think for some reason it is the nature of the recycled, however not sure why David posted about the Tambora.

Darren:
Most adhesives are too thick to make a good fill for holes this small; you'll get too many air bubbles. I would get some thick super glue and right after application, hit it with some accellerator. It will be ready for sanding almost immediately.
Have some thin super glue on hand too.
It is counterintutive, but it may be easier to take a diamond-tipped Dremel and make the small pits larger than struggling to fill the small ones.
