I have been watching a lot of youtube videos on turning techniques since i do not know anybody in this area that turns...i have seen several guys useing hot glue to hold the scrap stock to bowl instead of wood glue. Sets up faster and easier to remove..but my question is how safe is that? doing outside of bowl with the live center up i dont see a problem...but when you are hollowing the bowl..i am not so sure.
hot glue holding bowls in place?

When I do Hollow forums I like to glue a waste block to my wood before I start, I tried the hot glue once an as I was hollowing it came apart so I had to clean off the hot glue an used Titebond an never looked at the Hot glue again. So I don't recommend it for Hollow Vessels at all
That is what i was figuring. Thoughti would ask before i send a piece of maple through my garage wall nd into neigbors garage. Thank you.
There are different types of hot glue. Most are familiar with craft type glue guns which don't provide much holding power and could be dangerous on a lathe. There are also commercial glue guns that are entirely different. You have to be very careful watching Youtube. There are some real crazy techniques being shown by idiots. Work coming off a lathe is going toward the operator, be careful.

I did use hot glue when I 1st started doing small bowls a couple years ago. And it did work. I hated the cleanup. After I bought a G3 chuck I never used hot glue again.

The paper joint is strong. I do not use hot glue though, I just use normal Titebond on both sides of the paper. Takes a little longer to set up but stronger and I feel safer than hot glue.
The paper doesnt ripout? wouldnt think that it would hold..hmmm..

No, quick sharp tap with a mallet and the paper gives way. End up with a portion on the scrap piece and a portion on the work piece.
Ok...so i dont have a chuck....so super glue paper to scrap and to bowl blank...screw my scrap to faceplate and that will hold without tailstock in place? (just making sure) if so..that is a sweet trick. And up to what size would you say that is safe?

Be careful with Super glue or CA glue as we call it. That glue is brittle and good catch will snap the joint. I use it constantly for my hand mirrors but I seldom get a catch and they are small in weight. I've had platters break free just from aggressive turning.
Paper joints work great, I've used them for years. They can be brittle if you have a small area but on large areas they are very strong. I don't use them on bowls. Most of the time I just glue a blank to the bowl blank if the wood is too small. When I'm done I just part it off using a parting tool.
Hot melt glue can be finicky. If you just put a big plop down and stick the bowl on the glue can easily start to cure before you get the blank down and it might not be as strong. I used to heat up my faceplates before using the hot melt glue. When I used waste blocks screwed to the faceplate I would turn a rebate for the bowl tenon. I would start the bowl between centers and turn a tenon. Then I would use a wasteblock larger than the tenon. I would turn a very shallow rebate the same size as the bowl tenon. Then put glue down in the rebate and stick the bowl in. The I would apply glue to the outside of the tenon. This is very secure.
