Well the day with a nice conkerberry blank and as I got into it I found cracks hairline,so out with the super glue the outer surface was perfect but when I started inside a couple of pieces let go so that was the end of the conkerbrry blank I had cut up a log 600 long x 150 diam penblanks and intarsia wood, yes Ken a good piece would be good for the project. No 7 a tallowood burl blank turned beautifly achieved a result my challange complete I have photos of the progress but from different blanks so when i coordinate them I will put them on.
These look great! They are on my list of things to try, but I have a feeling (from the one failure that I have) that my skills aren't on this level yet.
I started one today - or rather, a lattice insert for a pot-pourri box in the box challenge - and had finished cutting all the rings, when I noticed a slight chip out on the outermost edge while it was offset chucked.
So I thought "a quick touch of the scraper will fix that..."
I think it did. I don't really know... 'cos it did a Robbo and took off down the drive, disappearing into several square metres of undergrowth.
Bugger.
Somehow I don't think my WIP will make it online... yours will have to stand by itself.
Hi Dave
Yes the grouves are square although Hans takes a small chamfer off the topedges of his. The tool is basicly a square scraper about 1mm wide and to get round the radias of the first rings its tapered away at the botton see photo.
This is the lattice box made from boxwood by Hans Weisfogg at Turnfest 2006 and again at Turnfest 2008 that inspired me to take up the challange to make these boxes number 8 attempt today, yes I had a blow out today one grouve not quite deep enough on the top then when I tried to open up the underside I went too far and lost the first five rings on the middle but it is a way of learning the importance of accuracy.
Ken I didnt have any olive wood but have some native olive from Tasmania it worked well.
1 Blank 60mm in diameter x about 50 mm high rounded and parting off aprox 15mm for lid.
2 Ditto
3 underside of lid mark centre with point of skew and 20mm radius
4 drill 2 x 6 mm holed about 8 mm deep to allow for mounting an chuck on right.
5 mount on chuck and true face dead flat this will become the top of lid , cut 1x1mm rebate on edge of face this will act as depth mark for grouves.
6 Remount lid offset on chuck and mark centre when spinning with point of skew
7 Drill 1mm hole imm deep
8Proceed to cut grouves with scraper to the depth of 1mm the first three you will have to guess as they wont reach the edge with the depth mark on it. Stop the lathe and check after each cut too shallow and the cut from back wont come through and too deep and you willbreak out on the otherside.
9 With all the grouves cut light sand and brusk out grouves.
10 Change to soft jaws or jamb chuck cut recess for fitting to base and hollow to 2mm thickness must be wery flat and sand.
Lattice Lidded Box part 2
10 continued after sanding mark centre with point of skew and drill 1mm hole 1mm deep care must be taken in next few moves as this is the crisis point in other works success or start again.
11 proceed to cut the grouves imm deep stopping to see wheather you have reached depth or not if deep enough you will see small diamond shaped holes where you have broken through the bottoms of the grouves on the top. As tis is an opperation that needs the finest of control after a few cuts you can hear and fel the point of break through but you need to check sometimes two or more times on each grouve to steady myself for this delicate move I found leaning tight against the lathe with my armpit resting on the tailstock so that the forward movement of the chisel was restricted and guided by my left handfixed on the rest and the thrust forward by thumb and fore finger the over cut of the most minor measurement here is critical.
when all the grouves are completed remove from chuck and clean debree from grouves some may not holes may not be clean these can be pushed out with a pin the wipe a wire brush in direction of grouves for final clean.
12 Now mount the base in the chuck and finish the base and sand.
13 turn dase around and remount with top facing out and cut recess for lid jamb fit lid and clean up sides and sand.
14Hollow out base and sand.

The finished box was given a coat of wood oil and wiped dry.
The timber used in this box is native olive from Tasmania.
I hope I have explained the process clear enough for you to understand. however if something is not clear please ask and I will doo my best to help.
