Joint Repair

[flatiron113]

Have an item that has an 18 mm female joint that snapped off. To repair what are the steps to follow? Heat up in kiln, heat up in torch and snip off to make clean attachment point. Then heat both the new joint and working piece to even temps and then stick together? I'm new at this and just wanting to repair a broken piece. Li realize that it can crack the glass when repair. What are tips to afford this?

I'd like to see where this thread goes, You have the basic concept down... but do you have the practice to pull it off? Not saying you dont asking a real question since you only Joined this month and Have 3 posts, I totally understand some people join after working for years and explains their new date but wondering hoe "new" you actually are.

If thats the case, might be better to practice a bit and put this on the shelf til you are ready

If its a clean snap and you have both pieces just set it in the cold kiln all together assembled, let kiln heat up and just do the repair inside the kiln with a hand torch.

The "suck seals" shown below are a quick way to make a "T" seal on a piece of apparatus. Properly made, this seal is strong and durable. However, if you have the choice, the
traditional way of making a "T"seal
is the preferred method.

Step 1

Thicken the wall on tube b - maintaining or slightly increasing the ID.
Heat an area of tube a about the same diameter as the ID of tube b.
Remove some of the heated glass - leaving a very thin wall section.
Step 2

While heating the end of tube b and a, quickly bring tube b down onto tube a making full contact. Then suck in quickly, causing the glass bubble to burst, and pull up on tube b.
This step has to be done quickly! The bubble does not burst if allowed to cool or if the glass wall is too thick.
Be sure to pull up on tube b while the glass is still soft to create a smooth even seal.

As stated this is not the best way to do a seal but if it is a repair this method is probably the fastest and with the least heating/reheating to "work out" a seal.

Defiantly don't have the practice to pull it off. I have the other half and it was a pretty clean snap. Maybe I'll put that piece back. I may take a few cheap joints and snap them off and practice re attaching to them.
