Nope, it was maintaining all fluid levels, charging and the battery was charged. Before I sprayed the cylinders with CRC I probed with a piece of cotton twine to see if anything had leaked in, checked out dry. Frosty The Lucky.

Frosty Posted June 30, 2019 Share Posted June 30, 2019 I did it because I wanted a hot car but couldn't afford much so I bought what I could afford and built what I could. It's a Southern California thing maybe. I was just never very good at it, I could get by just not very good. Frosty The Lucky. Quote Link to comment Share on other sites More sharing options...
Mikey98118 Posted June 30, 2019 Author Share Posted June 30, 2019 What I wanted with a car makes every father of daughters grind teeth; fortunately for all concerned, my old junker took up all my money and time for two years. By the time I traded it away, "getting ahead" had become my goal Quote Link to comment Share on other sites More sharing options...
Frosty Posted June 30, 2019 Share Posted June 30, 2019 My parents made us work if we wanted spending money so Shannon and I had jobs since we were 8 for me, I think 9 or so for Shannon. By time I was old enough to buy a car I had money in the bank and only needed to get old enough for a good job. Boy was my first car a education, like any kid I had zero idea how expensive a car really is. Buying it is the easy part, I had to cover how much me driving drove up the folk's insurance, fuel maintenance, etc. Ain't cheap I scraped to own my first couple. I couldn't afford to date, I had a car. <sigh> Frosty The Lucky. Quote Link to comment Share on other sites More sharing options...

I don't have any fancy words for this and you and Jerry have gone over this in depth. However could this be similar to how a backdraft in a house fire acts to draw in oxygen? once the fire has consumed all the oxygen the fire stops but the heating continues and will either burn out or suck in more oxygen. (at this point if you open a source of oxygen you get a boom) If the heat in our forge fully consumes the air induced through the burner then in those split seconds it needs a gasp of air to keep the flame itself going would that not cause the forge itself to draw air through the burner mount? I could be way off or just repeating what you guys have said. I have only spent moments trying to understand this small portion but it intrigued me. I just watched a documentary on blackholes and they were talking math way beyond my scope but I couldn't help thinking that there were similarities with how forges and burners move particles around. Now if only I could figure out how a black hole works I'm sure I can get this burner dun up good If this adds nothing to what has already been said there is no need to repeat what has already been said it is just how my brain wants to invision the mechanics of it.

Frosty Posted July 10, 2019 Share Posted July 10, 2019 NO, not if the burner's tuned. The propane primary pressure driving down the center of the mixing tube creates low pressure that induces combustion air in the ports. While a low pressure zone IS drawing combustion air it's not really the same thing. Back draft is more about what and how the vacuum is made to draw conbustion air, it's not the same cause. Same effect though. . . sort of. Some types of sputtering is a back draft effect but Ive never seen it happen to the forge itself. Good question, it's not going to be long and you'll be explaining how burners whrk and answering questions for us. Frosty The Lucky. Quote Link to comment Share on other sites More sharing options...
Mikey98118 Posted July 10, 2019 Author Share Posted July 10, 2019 It is important to remember that the burner, and its flame, are located near the entrance to a hole in the forge body; this gives access to outside air. The flame makes a reasonably strong force blowing gases into the burner--near this hole; this induces plenty secondary air through the hole, and into the forge; enough to seriously lower forge temperatures, if the amount of secondary air isn't limited. This is done by induction, in a similar manner to air induction within the burner, but is a separate process. Quote Link to comment Share on other sites More sharing options...

I think I am starting to be able to get a good visual in my head with this stuff. Reading and following instructions is great but I like to understand first so if I run into a hiccup I can work around it. Both your points of view in this really compliment one another and make it easier to form an image even during the times you disagree. Two more questions both of which I have not seen a "measurement" for here. 1: After insulation, ridgidizer and KOL how much wiggle room should there be between my burner nozzle and the insulation/KOL. 1/16"-1/8" creating another "step" and then stuff the mounting tube from the outside with scraps as needed? 2: A nozzle is used to reduce pressure so that the gasses can slow down enough to not blow off the end of the burner when lit. This would cause the flame to burn inside the nozzle a bit "holding" the flame.... I believe I read that the flame starts inside the nozzle (somewhere here can't remember the page) but how far in should that be or should it be hanging off the end of the nozzle? Does the flame still technically start at the end of the mixing tube and the nozzle literally "hold" the flame in place and that's why nozzles become consumables?

Frosty Posted July 10, 2019 Share Posted July 10, 2019 You are making a common beginner's mistake and seriously overthinking this stuff. The difference between 1/16" and 1/8" annulus (gap) between the burner and shell is insignificant. Moving the burner 1/8" - 1/4" more or less deep in the liner will adjust inducing extra combustion air more than that difference in annulus. JUST like moving the nozzle (Mikes method) or the jet (My method) of adjusting the induction ratio hence fuel air ratio. I do NONE of that with: calculations, psi gauges, flow meters, thermocouples . . . anything but eye and ear. Frosty The Lucky. Quote Link to comment Share on other sites More sharing options...
Trevor84 Posted July 11, 2019 Share Posted July 11, 2019 I guess to simplify the question regarding gap between the burner and shell would be "how big of a hole do I make/leave" Once I have the insulation in, hole cut, ridgidized, coated with castable should my step nozzle JUST slip inside the hole or have decent wiggle room? I guess I over technicalified my question, I just don't want to line the forge and cast it just to find out I made the opening too small. Too large and I can always add a little more refractory I guess. The second question would simplify to "does the flame start inside the step nozzle or hang off the end" mine looked as though it started inside a bit, the depth changed depending on the mixing tube length and psi. FWIW I don't have a fancy calculator nor would I know how to use it yet. I've just been trying to ask my questions more technical so you guys don't have to try and guess at what my idea of "wiggle room" equates to that's all.

Frosty Posted July 11, 2019 Share Posted July 11, 2019 Don't worry, Mike and I speak "wiggle room" and don't take it as a mistake, you're just doing what most of us did when we started out. Editing your profile is as easy as scrolling to the top of the page and selecting your log in name next to the Avatar. Select "profile" from the menu that opens, select "Edit" make any changes or just add your name so those of us with tree dented brains can look when we forget and save. Frosty The Lucky.

Trevor84 Posted July 11, 2019 Share Posted July 11, 2019 Ok name changed , check. I`ll leave my burner entry with a little wiggle room and add more refractory later if it's too loose, check.

Mikey98118 Posted July 17, 2019 Author Share Posted July 17, 2019 That is not a perfect flame, but is a mighty hot flame, and it is a large flame, which isn't an easy trick with this small a burner size. Could the flame be improved? Maybe, but the question to ask is do you need some thing more than you have? Only running it in a forge can tell you that. Sometimes, the search for perfection is the enemy of all that is practical. Frosty taught me that lesson. While you think it over, lets discuss your burner's flame retention nozzle, 'cause I suspect a lot of the burners performance is do to it. The taper is larger than standard; did you make it yourself? How much larger is it's inside diameter to the inside diameter to the tube? How did you form it? All the others will want to know too Ups! I misread your description of its size, but it is still a very hot flame. It would also be helpful for your imitators to see the rest of the burner Quote Link to comment Share on other sites More sharing options...
Swadly Posted July 17, 2019 Share Posted July 17, 2019 I ordered it from the place you referenced in a earlier thread id at flare is opening is 1 1/4" id at start is 1 1/8". OD of burner tube is 1" burner tube id 3/4" Quote Link to comment Share on other sites More sharing options...
Mikey98118 Posted July 17, 2019 Author Share Posted July 17, 2019 Thanks for the update. I have the nozzle sitting by my computer, and haven't tried it myself yet.

Mikey98118 Posted July 17, 2019 Author Share Posted July 17, 2019 The forgotten burner The Riel burner, shown on his burner pages ( freely available online), is one of the easiest and cheapest design to build. When the MIG tip modification shown on his pages is added, it remains one of the hottest burner designs around too I hope that people who follow my advise on burner designs don't confuse them for the only good path to burner construction. There are several ways to build a very fine burner; my druthers may not be yours. Quote Link to comment Share on other sites More sharing options...
Mikey98118 Posted July 19, 2019 Author Share Posted July 19, 2019 https://ronreil.abana.org/Forge1.shtml Over twenty years ago Ron Reil set up a website showing people how to build gas burners and forges; His version of the popular Australian linear gas burners became hugely popular for the very good reason that his designs and construction methods were simple and easily followed without much in the way of tools. I added an update to his burner, which is still shown on his site, and it became super hot; all very good so far... While his web pages have been preserved by ABANA, and can be freely consulted on the web, most people have no clue about any of this; they have just heard the label "Reil burners" and follow every Tom, Dick, and Harry's version of what they THINK is a Reil burner. The problem is that Tom just looked at the pictures and didn't know how to read very well. Dick got a look at his forge, and, and told Harry about it down at the bar. Harry thinks he's "smarter than the average bear," and made his own 'better' version, and that is what people are trying to build!!! Quote Link to comment Share on other sites More sharing options...
