now you get to feel what i have been feeling the last month or two. it's been -5 C at night here and about 1 or 2 C during the day :) your weather is what i see in the summer time most of the time.

sounds like an adventure and something to cross off the bucket list to me :)

The first time I saw snow was in New Zealand when I turned 50 but we did get up on top of a glacier while we were there after driving through 600 km of rain, hail, sleet and snow to get there.



But it was the welcome the Kiwi's gave me which included waving a spear up my left nostril on my actual birthday that was the most terrifying part.....


Clive has no idea how lucky he was to get out of the country unscathed!

Re the bucket list.
The Automechanika trade show in Shanghai is arguably the largest in the world now, just eclipsing Automechanika Frankfurt and SEMA running third. We are heading over with the AAAA, our industry association (like SEMA). I near sh!t myself when I found out there were over 6000 exhibitors! We have 28 rooms booked in the motel so its a sizeable group, big enough to get to meet the organisers.

My mechanic is coming with me. He's a lot younger than me and I'm sure he suffers from ADHD so it will be a funny trip for sure!

And one of my suppliers is travelling 4 hours to meet me and show us Shanghai one evening so that will be a bit of fun!

Anyway, we rummaged around this arvo and found my lambskin gloves I used to wear when I actually lived in a colder climate where at least we had frosts! No matter how good the car heater was, my hands just froze on the wheel without those gloves!

well cold weather or not you must be doing something right. to have the chance to experience an event like that and travel for work related stuff i would consider a blessing. what ever your doing keep at it it seems to be working well for you :)

i would probably pass on the spear in the nose deal though and be happy at home :)

i hope you enjoy the trip and gain some good stories to tell later :)

Well today was the first time I cut a full 2400 x 1200 sheet since I added a water table.
First observation is that Tommy was right . We made quite a splash around the machine because we don't have sides much higher than the slats. But becasue its only a half sheet table, we need to be able to index the sheet so this is kinda needed. I might look at working out how to add higher sides and keep the ends low for indexing sheets.

Second observation is how much nicer cut quality is. This really surprised me. What little dross that was on the sheet just knocked off to reveal a perfect finish with little effort and no grinding. Much better than cutting over air. Very happy about that.

Third observation is that I really need to add a parking position in Sheetcam to move to the centre of the table after cutting until the air flow finishes.

So a question. What do people use to knock dross off the sheet? Has anyone made a tool? If so what did you come up with?

PS. Plasmac's sheet sever features works really well!

I just throw the parts on the concrete, that usually gets rid of 95 % of the dross.

We have so little dross now with a water table, we were even wondering if the sandblasting as the part gets powder coated would be enough. I think it probably would be...

Today we stopped spotting holes and just cut them and even 6mm holes came out perfect for M5 clearance holes. The 9mm holes for nutserts are also perfect!
