Thread: Hot air and stirling engines
23/11/2009 11:43:34
Having a "Home Tigger" is CHEATING ( Lucky S*d), No Ian the project was shelved due to the Banana. Pulse jets are red hot within seconds of starting and having a localised hot spot due to the shape of the tailpipe (Aforesaid Banana) would have been pushing safety a bit TOO far, b*gger off  Stan 'n' Ollie.
 
  Besides, Pulse jets were Illegal over here at the time

You've mentioned the originators Peter, the HobbyMat was a later product of EMCO the company that made my MaxiMat. so if it worked before for them??

Aw Ian,don't be a spoilsport, the heavy solvents and cleaning fluids you mention were commonplace when we were kids and most of us have managed to survive  with one or two brain cells intact.
 
  We can't uninvent things, (Sadly in the case of mobile phones) but given a common sense approach to their use and KNOWING the hazards involved, why treat them any differently. Water is a dangerous liquid, you can drown in it and if you pour it into a strong acid??????
 
  I would be the last to scoff at Safety issues, why would I have started this thread, the only problem is the younger generations ignorance to what WE learned in normal day to day usage. I only needed to be informed that smoking over a trike tank (Trichlorethylene, later changed to "Safer" trichlorethane????) formed Phosgene in the smokers lungs. I already KNEW what Phosgene was.
 
  Banning or shying away doesn't solve the problem, but education allows us to use things safely.
 
   Remember, only some of a "Certain" age know how to fix a plug onto a cable correctly?? Thanks Lyyne Fawls-Wood, thanks a bundle.
 
  Regards Ian.

Try a centre drilled "Punch" a sliding diameter in the valve body (The Dia. ABOVE the ball hole). If you've tapped the ball and it doesn't seat first time, you have to square off again and try again. Re-read Rob's "Tap", VERY light.

Nurture the Tig specialist Ian.
 
  When trying to make another type of hot air "Engine" (a "Brauner design pulse-jet) I got my most experianced tigger to weld the longitudinal seam on a rolled up piece of 321 sheet. It still came out with a banana bend in it that no amount of planishing would remove.
 
  Stainless garden light stems? almost makes me think of having another go, flamin Chinese.
 
  And as a noted "Recycler" you know that Tig electrodes make super scribers and bits fastened into an appropriate holder are good for  groove turning and slotting tools??
 
  Regards  Ian.

Hi Peter, NOT a reccomendation but an observation of how the problem of locking the cross slide was solved by the illustrious designers of my own rotary scrap generator.
 
  The Gib strips on my own machine  are trapezoidal in cross section and are tensioned by cross slotted pointy screws with locknuts on them. It would still apply to one with a single angled face.
 
  The slide lock in my case is a Cap screw with a dimple in the end which locates a single ball bearing the diameter of which is slightly less than the root diameter of screw.
 
  What the manufacturers have then done is cut a square sided channel about 1mm deep ACROSS the face of the strip, which if the adjusting screws were removed, would still be retained longitudinally when screwing the cross slide in and out.
 
  The point about the ball being in a slot means that the strip is free to slide into the top corner of the vee when wearing.
 
  The problem with the dimple, and please DON'T take this as a personal criticism Meyrik, is that it holds the strip on a point contact against the tapered face, same applies to the soft rod with an angled face "Slug" sometimes used.
 
  You got three options Peter, choose whichever (Or your own concoction) you feel happy with.
 
  Regards Ian.

Sorry Chris, I've separated it to make the point I was trying to make more understandable, :-   "and Steel doesn't burn? A dry cell and wire wool disprove THAT misnomer."
 
  Just to give the correct name for the Alum. / Iron "mixture Martin it's called Thermite, and NO referance to Steel should be inferred on that sentance.
 
  Oh dear, Robert/Buster, Firstly, as a "Boatie" I'm sure that you have been classed as a "Boy with a Toy boat"???  ALL strands of the modelling hobbies wether boats planes or trains attract dispariging remarks by the uniformed observers, so in bringing our hobbies descriptions down to terms THEY can comprehend, it saves people like yourself ( NO insult intended) getting uptight due to THEIR ignorance of whats involved in generating/making a miniature replica for them to tut.
 
   You obviously haven't come across some of the bloated beachmaster /pondside Admirals in your chosen other interest???

"Doublecad" is a freebie by the makers of Turbocad, it's supposed to be a challenger to A/Cad Lite. After three weeks of head banging it's getting through, 18 years since I last played with Full A/Cad but there are similarities. Onward and Upward.

Firstly let me apologise to the other fori members for likening two to Laurel and Hardy, it was an insult to them (L & H) and at least THEY were funny.
 
  OK, how magnanimous of you Mr Griffith-Jones to draw a line under something YOU deem to be missinformed and a personal opinion. Thankfully free speech and opinions are not restricted or the patent of your goodself.
 
  As we've all had your carreer and qualifications stuffed down our throats, I'm surprised you have the time to waste on us lesser mortals, especially the F***wits you obviously abhor. One of the ways to communicate the safe operation of, as I mentioned in another post, this HOBBY, is for those without a lifetime in the trade to ask what some may class as stupid questions, so when you try to quote the periodic table to show the distance or not of various elements to each other perhaps you would like to consider Alumin. and Iron?
 
  Now ANY F/wit knows not to grind Aluminium? or perhaps NOT if you have just entered the hobby. Same with Iron.  Perhaps you could enlighten the assembled throng on how Railway lines were welded or even cut?? and Steel doesn't burn? A dry cell and wire wool disprove THAT misnomer. I can only repeat, tell those that have had Titanium fires that it doesn't burn, and as far as its use in muddle ingineering wasn't a series of pikkies at the top of the page showing clock wheel cutting using Ti.? More and more "Exotic" materials are being used daily by amateurs whose mates have given them a piece of metal cos they use it. IIRC some of the lowly Beetle castings were Magnesium?
 
  One or two safety prickorshuns save a lot of tears before bedtime so either think about some wise words or pre warnings to help the lesser knowledgible or in THIS topic, you don't have to reply.
 
  As far as the minimal use of Ti. in the UK aerospace industry, Lockheed pioneered many of the usages and manufacturing techniques in the production of the SR71 very many years ago. Seem to remember the Russians made a submarine out of it too.

Just as a heads up for Alibre users, it would appear that the 11.2 cheaper package is NOT compatible with Windoze 7 so it may be advantageous to keep a second computer containing XP or (UGH) Vista.

Thread: Auto Cad

If it's a genuine "AutoCad", you're drawing everything at full size anyway? However, a separate dimensioned copy is a good "Discussion" point with out having to look at a screen and do a load of enquiry dimensions.

As an alternative to the "Normal" paint finishes John, cos you're using materials capable of showing it off to advantage, have you thought about Chemical finishes??

"Measure twice and cut once" old adage from my mentors Tony and yes, we ALWAYS remember after the event, what a wonderful teacher hindsight is.
 
  Just ensure you restrict your "Occurances" to materials and not Soft tissue. No matter how annoying, it's a HOBBY.

Another thread in danger of being hijacked by the intrusion of Stan and Ollie, however, good points by Paul H and Chris H so what about it D C??? and just to clarify for those who are able to listen and note, the guys who HAVE had Ti. fires will tell you that it DOES burn as fierce as Magnesium.
 
  Cautionary regards  Ian.
