Waterjetting

Ahhh .. Waterjetting .... Another highpoint in technological innovation for me .... Heres a short excerpt below from the fascinating Wikipedia entry describing their history and applications ... Cutting food? Hmmm... wonder what thats about ... Click the pictures to enlarge them.

Materials commonly cut with a water jet include rubber, foam, plastics, composites, stone, tile, metals, food, paper and much more. Materials that cannot be cut with a water jet are tempered glass, diamonds and certain ceramics.[4]

Water jet cuts are not typically limited by the thickness of the material, and are capable of cutting materials over eighteen inches (45 cm) thick. The penetrating power of these tools has led to the exploration of their use as anti-tank weapons but, due to their short range and the advent of composite armour, research was discontinued. Anti tank weapon ... Whod a thunk it?Matt Santwire of A L Melanson in Rutland at the controls. Importing the files that we created in Dorset, emailed to him, which he then toolpathed at the computer in his office and then sent to the computer you see here that controls the cutting ... Thats a lot of computing, trust me ... The machines surface is actually flooded and the material is under water when it is cut. Since there is no force the material is held in place usually just by gravity on the supporting bars you see in the top photo.Findng home, the starting point for the computer file ...

These are the parts of the ducks which will be inlaid in the finished kingsize bed we are working on a couple posts below. Looks like it was easy when its done ... Wasnt ... All the little bridges were drilled out and the tabs sanded or filed off on the edge sander...
Other products we have made with the waterjet ... our aluminum windsors ... the back is springy like an old lawn chair ...
The base for the claro walnut table we just finished ...
1.5" thick cold rolled plate steel ... Tough stuff ... Took an incredibly long time to polish it ... cant imagine cutting it any other choice ...
This is the first sample center inlay we made on our first trip to Maelansons. We discovered that the cuts are ever so slightly tapered as the jet spreads out slightly once it penetrates the surface, so we cut all the inlays upside down. That was a handy feature when we fitted them into the routed pockets on the headboard as they tightened up as they went in.
First sample of the center ducks in aluminum, back side ... You can see from the cad drawing that the image has been flipped ... good trick ...
Into the finished headboard sometime next week .... The polishing and fitting of the individual inlays and metal parts was done by Trevor, Will and Sam, coloring of the finished inlays was by Sam. Jim lent a hand in the early stages ... A total team effort for sure ...
Trevor cut the pockets for the inlays using our cnc, using a 1/16th" bit and a 1/32nd" bit for the final pass on the outline ... Amazing .... Stain color looks a little funky here because of the light .. Its going to be real nice I think when its all done ...

Literally Working On A Table

Yesterday, Trevor gave us a new meaning to the phrase working on a table ... Here he is, literally, working ON THE TABLE ! And, theres plenty of room if more of us wanted to get up there and work on it with him. ... And, this is less than half of it ... 3/7ths of it to be exact. Anychoice, its coming along. Today Jim set up a temporary frame for the whole table in my garage and it looks like I will just be able to close the overhead door once the top is all in place. We feel we have to have the top with the center sections and granite templates all together at least once before we call the gentleman who is going to pick up the templates and cut the granite. Cant be too careful on this one, and it wont fit in the shop. Click the pictures to enlarge them ... Plenty more on this project later ... Its a big one ...
The far end ... The first four sections not shown here have already been fitted and edged. Here, we are cutting the templates and the preparing the center sections for veneer ..
With the end section removed and the center section of the table now in its place ...
The temporary base in my garage with the steel tubing in place and the end caps welded on. Next, as each section is finished and the steel is primed, well put everything in place and bolt the table sections to the steel and they will be finished like that.
