Wonder Window blank?

[qquake2k]

Has anyone turned a Wonder Window blank? How exactly did you do it? The instructions say to turn it "roundish" so you can see where to cut and drill it. But it's rectangular, not square, so it won't center in a chuck. Maybe a spur drive with a spring loaded point?

Hi Jim
I always turn any square blank round, the easiest way I find to do it is mark off the centre off both ends of the blank then centre drill the ends then I mount it between a spur drive centre and a revolving centre on the lathe and turn it round.

I thought about using my chuck, but the problem with that is the round blue portion of the blank isn't centered in the rectangular red portion. But I'm not sure a spur drive would "bite" an acrylic blank enough. I don't know what to do.

I sanded both ends of the blank, and now you can clearly see both centers. They're definitely not centered.

I would use the above in the head stock and this in the tail stock.

Take the advice Ed Street gave you Jim.

I use a spur drive on acrylic blanks Jim some bite in better than others but I only take light cuts on the harder ones, also I use a small metal turning lathe on automatic feed if they are really hard.

If your drive centre is a 2 pronged one (like this 2 Prong Drive Centre 25mm(1") - Drive Centres - Woodturning Fitments - Lathe Accessories - Machinery Accessories - Accessories | Axminster Tools & Machinery ) then mark the centre of that circle and make a 1 mm depth cut in the end with a band saw (or fine hand saw) and then place the prongs into the cut, if its 4 prong then make 2 cuts at 90 degrees.

That's what I do. Drilling the blank first is daft IMO, not sure who came up with that idea but suspect it was the tool sellers.

I use small and medium Steb drives would do the trick as well.

I've decided to cut the blank in half before I initially turn it round. I sanded the side a little so I could see the center of the pattern.

An independant four jaw chuck would hold it ready to drill.

Maybe, but it would be difficult to get it centered.

I cut it in half.

Looking forward to seeing the final results with this blank Jim .. :wink:

I think I would have gone with the way Pierre suggested.

Talking time is over mate lets see the pen. At that price the hopes are high.
