    Optimal number of boiler tubes.

    Useful for straight forward type substances. Now what about for bio-mass - - - and that would likely also depend upon the type of (I would bet!)? TIA

    Optimal number of boiler tubes.

    Grin - - - of course I have a real application - - - but its not in the 3" copper tubing size category. At least a couple steps larger. I'm looking for independence from the powers that be - - - they seem to think that they can legislate mass stupidity and I'm still in the resisting stage...

    A Micro Drill Press

    Thank you for the information! I had hoped that you had a wider range of rpm than that. (drilling holes at 0.020" (0.5 mm) you need some 15k rpm with HSS bits - - - 5k rpm puts a limit at somewhere around 0.050" (1.5 mm) - - - bummer!) (am looking at some nozzles with an orifice size of...

    Optimal number of boiler tubes.

    Hmmmmmmmm - - - have been following this thread - - - - fascinating AND interesting. The base equipment is a 'fire-tube' system. Wondering if there are any links to similar 'conversations' re: 'water-tube' systems? TIA

    Nice!!! Especially appreciate the plan source! Please - - - - what's the available rpm range? What are you using to power this lady (she's not just a girl - - - grin)? TIA

    Electric Starter System for Model Engines

    Hmmmm - - - -Shipsy only works if you're in Ontario, BC or Quebec - - - so not of much use except if you live in those areas. (There's plenty of canuckistan that isn't in those 3 provinces.) Thanks for the info - - - maybe they will expand their services - - - dunno.

    Electric Starter System for Model Engines

    Y You might want to check your exchange rate mr Brian - - - - I think you'll find it between 0.72 and 0.73 about now. I don't mind paying the exchange but the added fees because its crossed a border are outrageous and then shipping cross border isn't even that good. For example - - abebooks...

    Monotube Flash Boiler Design

    Corliss Steam Engine (Coles Power Models)

    Yippee yippee - - - - is the chez Zapjack also open (giggling)? So what did you do re: your power requirements? (Curious to know.) I'd bet its a great feeling - - - finally done with the moving (and 1/2 done with unpacking and organizing all the stuff I'd bet!).

    Question about putting VFD on a step pulley mill.

    More useful information - - - thanks!

    Looking for cast iron bars

    One of the biggest problems you'll run into if you're not in a seriously major urban area, or right close to it, is the ability to find much of anything less than a tiny list of things. Because you are not in said area you will also find your pricing reflecting this - - - often to the point of...

    Looking for cast iron bars

    Dunno as to your location but Metal Supermarkets is a goto for small quantities of a lot of stuff. They don't have everything and their pricing is stupidly high but what they have or decide to get for you is available in smaller quantities. Just checked and they don't seem to handle Durabar...

    Interesting - - - thanks!

    Question about putting VFD on a step pulley mill.

    I have need of some vfds but have hesitating in buying. A large part of the hesitation is due to the enormous difference in pricing that I can find. I can buy from NA name brand distribution and its XX$. Or dig around and find the non name brand NA distribution (there are a few) and its 65%...

    I would be willing to bet that for non big dollar purposes the short from ASME would work quite well. Do you have such info?

    Questions regarding drilling small holes, and runout.

    OK - - - - I'll ask the almost stupid question. I'd love to buy top quality tools - - - that would mean that I just wouldn't be buying. Just don't have the funds to buy things at that level. So how about recommendations of collets that are reasonable AND don't break the bank. There's got to...

    Removing pulley from a motor spindle

    A tapered gib key is a great holding tool - - its also a tough thing to remove. You have a bit of room as I can see (photo isn't quite sharp when magnified) between the pulley and the body of the motor. What I'm going to suggest is counter intuitive but I've had it work a few times (but no...
