Topic tags/keywords: turning bowl lathe

I’ve done a few simple, shallow bowls before and would now like to try a square edged bowl and found plans for a small one with instructions..

Some questions:
1) I don’t have access to stock thick enough (1 3/4”). Can I glue up 2 1” pieces and use instead? I guess this wouldn’t really be any different than glued up segmented turnings?

2) As you can see in the pic, the turner starts turning on the faceplate side of the bowl, which I’ve never seen before. Is this safe? Any guidance here appreciated..

Cheers

Watch 10 turners and see 10 ways to do something.
I’m big into using the tail stock as well as glue blocks. Just makes me feel safer.
Remember that you’re turning air on square bowls. Watch out for catches.

I have turned several shallow less than 1” thick square or less bowls as well as deep 3” square bowls. Do use chuck or faceplate with waste block & paper glue joints on supper thin square bowls.

If were you would do to Google or Bing image search for some design ideas and throw your plans away. Just have fun with wood you do have on hand.

Good luck with it!

You should be able to glue it up.
I think of a square edge bowl as one in these videos, not as the one you show in your post.

i neglected to mention this bowl is square after its turned and then 4 sides sliced off with bandsaw or tablesaw, so it is supposed to be safer than turning air.

I’ll answer question #2 with a question. How else would you turn both sides of a bowl if it’s mounted to a face plate? ........ Jerry (in Tucson)

Good question! The article shows this, then removing the bowl, turning a “spigot” on the faceplate and turning the bowl around with a friction fit on the spigot to finish turning the under side. So my question is, if they were going to do this anyway, why bother with turning on the faceplate side?

Because gives you the opportunity of turning both side of the bowl before reverse turning. Majority of the bowl completed (turning, sanding, & finishing) before reverse turning and complete bottom.

Before had a chuck and used nothing but faceplate, waste blocks, and paper glue joints would turn the bottom of any style bowl before reversing turning. Then glue bottom to waste block wait for glue to cure before turning inside of the bowl. Would turn, sand, & finishing 99% of the bowl before reverse turning and finishing bottom of the bowl (remove paper & glue residue, sand & finish). Back then would mount my bowls in homemade donut chuck to complete bottoms.

Today seldom use any of my donut chuck various chuck components on bowls and use jam chuck. Start turning bowls/hollow forms between centers using spur drive & live center before mounting in scroll chuck or on a faceplate.

Like Bill White said above many ways to accomplish the same task. Also we are not seeing complete plan & safety notes you have.
