I just need to find a good epoxy to attach the gate to the base. Adrian recommended Bison epoxy. It is said to be good on metal and stone - which are the two things being attached. But I can't seem to find a US supplier. I also was thinking of the Gorilla super glue. www.homedepot.com/h_d1/N-5yc1v/R-100661959/h_d2/ProductDisplay?langId=-1&storeId=10051&catalogId=10053What do you all think. If it helps, here are a few more details on what is being attached. The stainless steel posts from the gate are going directly into the holes Adrian drilled into the obsidian. There is significant play for the posts in the holes, so whatever adhesive I use will need to fill well without shrinkage. The bottom of the posts are threaded, so that should help with the adhesive getting a firm grip. The gate is top-heavy, so the adhesive will need to be strong. Any suggestions on what should be used?? Thanks all. Really looking forward to getting this completed... |

Gorllia glue expands and makes a horrible mess when dry. I wouldn't use it on this project.

Would you be needing a glue with a high viscosity? I have been using Hot Stuff green does a good job filling. That is what I used to repair Teddy the broken Cab from Mary Ann. I got mine from Kingsley North www.kingsleynorth.com/skshop/product.php?id=97590&catID=594I am also in the process of doing a field test for an epoxy putty. I will be posting a review of this product on this forum as well as some others. This stuff is remarkable. I will be doing a repire of a broken vera cruz amethyst crystal point that became detached from it's matrix. A very challenging repaire that only a putty type consistancy can handle. There is another product used by many museums for resteration work called hxtal. It is a bit pricey but you have a lot of control over viscosity and other variables. Good luck Stu |

I use the Devcon 5 minute (clear)epoxy a lot. When set it's much like the 330 (I use it too) But sets much faster. It does come in black too I believe. If you wanted it to blend in more with the base.

I recently got some glue called Zap a Gap at the rock shop. It is recommended for filling divots and gaps in stones. It is a type of CA or a real super glue. It bonds in seconds and is waterproof after curing. It can also be polished with no problem. I just repaired a crazy lace agate paper weight I am making for my wife`s desk top. An unseen fracture dropped out of a corner of it when I made my final cut on the saw. This glue is for use on glass, ceramics, metal, rubber, plastic or any nonporous materials.

Gorilla glue is really bad, it expands sooooooo much! I've been in tears before because I tried it on furniture......
On the other hand... DANG I have been waiting soooooooo long to see this project complete. I can barely wait!!!!!!

For ease of application the putty epoxy would be the way to go. Just mix the putty together and drop it in the hole and insert your rods. Other than that, I would use the 330.
Whatever you use you will get a better and more permanent bond if you wash out the holes and rods with acetone.

Yung uses a glue called E-6000 on her Gem Trees. It is available at most craft outlets. She used to use one called 427. She now panics when she is getting low on E-6000. It bonds her wire onto a rock base very well and drys to clear. She has had zero failure with this glue and once in awhile I see her removing the tree from the rock so it can be redone if needed.

Hey Todd, I think any epoxy brand would work, if you don't find Bison. I would choose slow hardening one rather than "5 mins", to avoid the hurry. I'd avoid super glue, if the super glue you're talking about is the one shat stucks to the fingers way better than to anything else. Oh, and another hint: for placing that gate vertically do the following: 1. Before you insert the gate into the holes, draw a line with a marker on the obsidian base (from one center-hole to the other); 2. Attach a chain from one of those wire links you find on the lower beam (the chain should be long enough to be close to the obsidian base, but not touching it). 3. Fill the holes with epoxy. Add some epoxy on the threaded ends of the uprights, as epoxy would not penetrate very well by itself in those narrow grooves. 4. Insert the gate in the base. Do the duct tape thing, as I told you in the PM, and for the gate to be in vertical position look at the chain to be above the line you drew between the two holes. 5. Clean the excess epoxy on the base as soon as you can (another reason not to use 5 mins epoxy). After removing most of it with some tool and paper, clean the base with acethone (but be careful around the gate's posts, not to add acethone under them). 6. Remove the duct tape only after 24 hrs. 7. The small traces of epoxy can now be cleaned with a knife blade or a cutter. Do not use the cutter to remove the epoxy traces from the stainless steel parts, as they could be scratched. After this, clean again with acethone. Oh, and take pictures and post, of course  Good luck. Adrian |
