Temporary Face Plate Block?

>Hey Tommy,

The paper that turners used to use for glue blocks was a brown kraft paper, just like an old paper grocery bag. But, nowadays, I don't know of any turners that even use paper, just glue the block directly to the blank.

I'm sure others will chime in here.

>A few turners still use the paper insert between the glue block and the turning blank. Most use old paper grocery bags as the insert. This was a method used when the blank was mounted on the waste block and then fully turned and finished while mounted on the waste block. A thin chisel was then used to separate the paper and remove the bowl from the waste block. Finally, the base of the bowl was sanded and finished.

Today, most turners reverse the bowl to turn the foot after the rest of the bowl has been turned and finished; therefore, there is no need for the paper insert. Simply glue directly to the waste block and then when the bowl in finished, part off the waste block, reverse the bowl and turn the foot.

Since I use chucks, I mount each bowl three times. First between centers to form the outside and to form a tenon on the foot to fit my chuck. I then reverse the bowl and grip it in my chuck. At this point, a light scrape cut may be taken on the outside to make sure it is true to the mounting. I then hollow the bowl, sand and finish. Finally, I reverse it onto a jam chuck or a vacuum chuck and final turn the foot.

I believe that a great many turners use this latter method. Some start out on a screw chuck rather than between centers, but otherwise the process is the same.

>Thanks guys,

This particular turning cannot be reversed so I will not be able to turn off the block. So I'll give the brown paper a try. I appreciate the info!

>Thomas, the process I use is slightly different as I do not use a chuck. I use a faceplate instead. If making a bowl or vessel with a larger than 3" opening, I start by attaching the faceplate directly to the "open" side of the blank to shape the bowl and create a flat on the bottom of the blank to attach my glue block to.

Then I mount the glue block to the bottom of the blank and attach the faceplate. I use CA to glue the block directly on to the blank, then hollow the inside and finish turn the entire piece. I use a 1" chisel to remove the bowl after finishing. I find that the CA releases very easily and the bowl just pops off the glue block. I then reverse the bowl in a jamb chuck to finish the bottom.

This process works for me.

>When doing deep hollow forms, I use a glue block rather than using the chuck. I've always glued directly to the piece rather than putting paper in between. Turning off the bottom of these deep pieces can sometimes be a pain. I'm wondering bow much strenght you loose putting kraft paper in the joint, versus no paper?

>I'm one of those "old" guys who still keeps a few brown grocery-bags around because it is the better way to hold some things.

The thick brown grocery bag is the better paper because the glue does not pepetrate all the way to the center of the sheet from both sides. Since there is no glue in the center of the sheet thickness, it can be separated.

The glue will penetrate all the way through typing paper, tablet paper, and news paper (the worst). The result is a paper reinforced glueline that is only slightly weaker than a good wood-to-wood glue joint, and it can be very difficult to pull apart.

Yes, either white or yellow glue works.

I did a test one day on glue joints for a demo I was doing. I found very little difference in any paper that I used. I use newspaper myself and have done a tone of split turning especially my inside-out pieces.

The trick is not to use too much glue so that it soaks through the paper. This isn't very tricky I still spread the glue about the same way as usual I'm just not as picky about getting glue on every square inch. I use titebond ll for paper joints and have never had one fail.

I discussed this with a turner on the other side of Atlanta. His company does hundreds of split turnings every year and he said they use newspaper as well.

I tried black constructin paper once because the project called for cleaning all the paper off which was a real hassle. I thought I could leave the black paper on the back and it would look good without cleaning it off. Not so. It looked like cheap torn paper.

I like to use hot glue without any paper. Take a look at the link.
