Something about embrittlement. Back when the Piet was designed, the steel used was not 4130 so brazed joints were shown in many places in the plans. Now that 4130 is the material of choice for aircraft structural components, folks think they can just continue to mix methods and there are issues with this. If you're thinking of doing it, at least check it out before you jump into it. For starters, go to the Matronics site, go into the Pietenpol list, and use the search engine on the word "braze" or "brazing". I'm no expert on welding or brazing, but I can tell you that as a result of that discussion one brazin' Piet builder is not a happy camper (sorry 'bout the pun but it's Friday).

"This steel has a definite grain structure that actualy opens up at medium-red brazing tempuratures. When brazing alloy is melted onto the steel surface, it flows easily into the many small cracks and crevasses in the chromemoly steel. Then, as the braze joint cools, the brass will not compress and it forces major cracks to form in the 4130 steel. Often, a brazed 4130 steel part will crack completely in two before your eyes as it cools. ================================= Dana- move over... I'm diving for your foxhole!

Message-ID: Jim, You aught to be flamed after jumping on Virg like that. I think that he might just be trying to encourage those who haven't bought the plans to do so, and if they have them, maybe they should take a look at them. I have seen many questions on the net that are clearly answered in the plans. Granted, with these plans you should use good sense and if something doesn't look right, ask the question. Maybe like, it says in the plans, to lay the cloth on the BID, why is that? Or, it says in the plans to use 1 layer, have you found that to be sufficient? Daniel R.

It is always nice to have someone share expert knowledge. What worked one time, one place is not necessarily the correct answer. Besides, I have not done extensive brazing of 4130 and claim no expertise in the area. I saw the practice used extensively in the Formula Ford community for safty cages. In the testing I did the 4130 tore somewhere between 1/2" and 2 1/2" back from the braze. I never experienced the cracks developing as Oscar reported. Maybe I wasn't putting enough heat into the brazed joint or maybe I was making some other silly mistake and was not following the proper brazing technic and just ended up lucky with strong brazed joints. I have never tried to repeat the experiment.

I strongly agree that tailwheel springs should be heat treated, but 4130 is not the ideal material to make them out of. Tailwheel leaf springs should ideally be made of 1095 spring steel. After they are bent and drilled they should be spring tempered. 1095 and a few other materials in the 1090 series are the only types of steel that can be spring tempered. This results in a bouncy tail spring that will absorb impact and still return to its original shape without permanently deforming or snapping like other steels will. I have two 1/8" X 1 1/2" leafs on a Matco tailwheel and they work great. Cost of the material was about $60.00 and heat treating was $55.00. My high costs were due to a minimum order for the material and a minimum batch size for heat treating. I still have a bunch of the steel left and would be interrested in selling a batch of heat treated leaf springs if there is enough interrest from all of you. For all of you that want to do your own you can get the material from Admiral Steel or McMaster Carr and find a local heat treatment shop or send it to a shop. If you do not need to bend it, you can buy 1095 blue tempered strips that are already spring tempered. If you need to bend it you will need 1095-O annealed steel and temper it after it is bent. It does not get too hard to drill after heat treatment, but it is easier to drill it beforehand.

I have no room on the top of the engine because of the AN fittings on the oil cooler. I can hang the cooler under the oil pan and still fit it in the cowl. The carb is an updraft Zenith and it will sit behind and under the oil cooler. I will be able to route cool air to the inlet of the carb. Is there any problem with mounting the oil cooler in that location? The warm air that comes off of the back of the oil cooler will flow around the carburetor unless I put the cooler in a box and route the air around it(doable), but I don't know if that will make much difference. I have also thought that if I put a box around the oil cooler that I can use the warm air off of it for carb heat instead of the heat muff on the exhaust. Any thoughts on that? ------------------------------ Date: Sat, 27 Jul 2002 15:28:30 -0500 To: From: "Mark Langford" Subject: Re: KR> Oil cooler location Message-ID: <010501c235ac$2c01d5c0$0100a8c0@TD310> Brian Kraut wrote: > Is there any problem with mounting the oil cooler in that location?

I don't see any problem locating the cooler down low, other than the fact that there will be that much oil that won't get drained at oil change time. I've seen several planes that way. > I have also thought that if I put a box around the oil cooler that I can > use the warm air off of it for carb heat instead of the heat muff on > the exhaust. Any thoughts on that? I definitely wouldn't do that. The cooler doesn't put out nearly as much heat as the exhaust stack, especially in the winter. My Karmann Ghia's oil temp never gets over 180F in the winter time, and it takes a long time to get there. Compare that to a 1100F exhaust pipe that warms up within a minute of starting the airplane. Carb ice is something that you want gone NOW, rather than in ten minutes or so...

Message-ID: I seems like every week, someone is talking about doing something else to this little airplane. This is a "sport" plane, much like a sport car. I liken it much to an MGB or a Spitfire. Fast, quick, and noisy. This is what it is. I think that changes, additions, and subtractions, are good, but everyone should really weigh... pun... their decision to add anything to this airplane. It is going to be overweight anyway, just cause, and every little thing you add to it increases the weight and decreases the usable load along with speed, rate of climb, increased landing speed, and everything that goes with it. You need to really think, really hard, before adding anything. Be sure you really need it for safety or a personal need that you cannot do without. This plane is so much FUN to fly that you will not even hear a sound that you don't absolutely love. Daniel R.
