Incredible!!! Things have come a long way since I spent 6 months learning to hover with 4 channels and no gyro back in the 80's! David

I echo all the sentiments above with the science museum a definite "must do", I take my kids there for a day at least once a year and they love it ALMOST as much as I do ;D , pretty much next door is the natural history museum which is just huge and awe inspiring. The great thing about most...

Hey all, Well it's been so long since I visited last that I thought I ought to say hello again. It certainly looks like you've been busy here, can there really be so many more members since October last year? Things have been pretty hectic here with a nasty monster around every corner so I...

Hey Ralph, Those Sortimo units are awesome and VERY expensive, when the salesman was selling me mine for the vans he made great effort to show me pictures of their crash resistance even when loaded with heavy tools... If you find any more going spare give me a shout!!!!! David

Hi RBS, you are right, those water trap filters are worse than useless IMHO, I use my compressors at least 6hrs everyday in all conditions for paint spraying and powering air tools: DA's, die grinders, air ratchets etc so use a lot of air in all weathers.... The problem is that there is no real...

I'm saying nothing Ringo,CC and I are all on the witness protection program.. David

Hi Eric, The test tube is 4"/100mm long with a id of .63"(16mm), the choke is a bit different from most lamina's in that it is a stainless or brass tube (I haven't decided yet) with an id of .12"(3mm) but it is 3"(75mm) long to bring the business end to the bottom of the tube. The bore of the...

Hi all, Bob Warfield posted this in Brian's super-duper horizontal double acting thread but I didn't want hijack it.... I was just wondering whether the same technique could be used but utilising soft solder instead, the only reason I ask is because I haven't tackled anything with silver...

Welcome Gearsguy, Pictures man!!! I'd love to have a go at casting and always find it interesting to read about the many different approaches but we love to see pictures here, I guess we are just nosey ;D ;D ;D David

Hey Spud... welcome

I was great to hook up with you guys, it may have been that the company was good but I felt that this show was in a different league to the Ascot farce... David

No input as usual from my end but the image I have in my head of it is bl**dy gorgeous!!

Well I don't usually have any trouble with parting off with my 7x as long as the machine is properly adjusted although that usually means doing it every 2 sessions and I haven't been working with particularly hard materials...... But I have been struggling turning 4.5" ring of Phosphor Bronze...

ah yes, I was kind of hoping you had all forgotten about that :big: :big: :big: :big: :-[ :-[ :-[

how did I miss this one??? Very nice build

Not sure what to make of that comment :big: :big: No, this is an all new pretty-as-I-can-manage design using the dimensions from the experimental rig. What are you making your "hot" end and your regenerator from, 5 minutes doesn't sound too bad. I'm coming to the conclusion that there needs to...

Hey Al, I get a cookie error when I click on your link, is this the tool you mean? If you need to find the listing at chrono the tools reference number is xc10 David

Had a reasonable day in the workshop yesterday, between worrying about why the phone hasn't rung for nearly a week :( :( I have the upright, base+brackets, cylinder assembly and test tube steady roughed out. I have to admit this is one of those projects where I have been so focused on the why...

ooh, I'm loving these kitchen science threads, it's a good job there is some distance between most of us, if we were all in the same zip code we could really do some damage (insert maniacal laugh here).... You got some good results there Kludge, definitely worth doing. David

I dunno how micro switches would last with all that arcing I suppose the capacitor would limit that to some extent but I wouldn't like to contradict Mr. Ridders. Keep going I think we are all with you at every step on this one, definitely EOM material IMHO. David
