If you like this, check out what else this kid has built.  I like the  one 
where he took 4 single cylinder Briggs engines and put them all together to  
form one 4 cylinder engine.  A bit crude, but still neat!

Melting lead 
You are allowed to expose yourself to lead if you choose.  I think most of us 
have, including me on numerous occasions.  But after watching a friend's 
illness with lead poisoning from bead blasting aircraft cylinders IN a bead 
blasting cabinet, I don't work with lead anymore without adequate precautions.  
I would suggest you describe your operation to an Industrial Hygienist and ask 
for an opinion.  You might be surprised at what they say.

I can tell you from work that I am required to take about the same precautions 
when casting, melting or forming Lead as when doing equivalent work with 
Uranium.  Once you get a dose of lead poisoning, you end up doing Chelation 
Therapy for years to reduce the amount of the heavy metals in your system and 
get your head on straight again.  The point of the post isn't that you can't 
melt lead and get away with it.  The point is that lead is highly toxic and 
there are other ways to form your counterweights without exposing yourself to 
the potential of lead poisoning.  Lead poisoning sneaks up on you first as 
memory loss or lack of ability to concentrate.  It can be confused with 
symptoms of aging, so Drs don't typically test for lead poisoning unless you 
tell them you have had exposure.  Chelation therapy can help you to slowly 
recover.  But it's best not to put yourself into the position to need it.

If one feels that they must melt lead, try to do so with good ventilation and 
take precautions to minimize exposure.  What was an acceptable practice in the 
plans from 45 years ago has been demonstrated to be unnecessary, highly toxic, 
and a risk to your health.  So why do so if you don't need to?

Jeff Scott's suggestion of lead shot in epoxy flox / or equivalent 
eliminates all the "CAUTIONS" expressed on "melting lead".  It 
works.  I did my elevator counterbalance  using that method.


I'm not sure if small shot with tighter spacing or larger shot is 
best for a smaller over all weight of the same size.  My guess is 
smaller shot.

Re: KR> Melting lead

Date: Saturday, Jan.28,2017
Subject: Melting lead and safety precautions

When making my counter weights, I built some molds out of plaster of Paris to 
shape  then used the female mold to pour melted lead into.  

ONE VERY IMPORTANT POINT HERE; that is heat the mold (plaster) in the oven to a 
high temperature to ensure there is NO water left in the plaster PRIOR to 
pouring molten lead in it.  FAILURE to do this will result in an explosion of 
molten lead that will cover everything with in a 10 ft radius INCLUDING the 
person pouring the lead!  ALWAYS WEAR PROTECTIVE CLOTHING, GLOVES, EYE, FACE, 
ARM, AND BODY PROTECTION.

Molds can also be made from cardboard and masking tape, yes some of the tape 
and cardboard will burn but will not leak before the lead solidifies and is 
easily removed.

I gave up trying to find an exhaust system that even vaguely resembles what I 
have on N891JF.  I'm going to have to build another one that replicates it, 
unless I want to remove the engine, completely reconfigure the firewall and 
intake system, etc.  Building a new system, as painful as that sounds, is 
easier than the alternative.

I was going to build it out of 321 stainless until I checked the prices. 
  A 321 U-bend is $94, a 304 U-bend is $40, and a mild steel U-bend is $10.  I 
need 8 U-bends (four are actually J-bends, but same price), just to think about 
getting started, we're talking $800, not to mention collector, tailpipe, 
flanges, etc, if built from 321 stainless.  The existing one made it to 600 
hours and was mild steel.  I'll have N56ML back in the air before I put another 
600 hours on this one!

By contrast, my Corvair system was almost reasonable built from 321, because it 
is built so simply using only three U-bends for six cylinders.  But it's not a 
complex 6-into-1 system either, just a pair of simple 3-into-1 pipes.

I have everything I need to start on it, and that's what I'm doing all weekend, 
and probably next weekend as well.  I built two mockup engines, one with the 
old exhaust to measure distances and angles from, and the other as the fixture 
to build the new system onto. We'll see how it goes.

One thing I learned along the way is that Great Plains has no exhaust systems 
built, but they do have fixtures, so they are "to order" with a
30 day lead time.  The configurations are shown on their website at 
http://greatplainsas.com/scexhaust.html , none of which are similar to mine.  
Also, gauge size is not mentioned on their website, but they are 18g (.049"), 
rather than the 16g (.065")like the original exhaust system, so I had to get 
all materials elsewhere.  I did buy flanges from them, but am not enamored with 
them as the mounting holes are huge compared to the 8mm studs, so I'll have to 
carefully center the flanges to the ports before I start welding tubes to them.

I used an electric melting pot when I was doing a bunch of reloading.  If you 
want to keep the lead "clean", drop some parafin on top the hot lead and stir 
it and it make the junk float off.  WATCH OUT.  Sometimes it will FLASH OFF.  
Face shield and gloves should be mandatory for protection.

Re: KR> 4-into-1 exhaust system help?

2017-01-28 Thread Randy Smith via KRnet
When it was time for my exhaust on the KR I Talked to a local muffler shop and 
then loaded it up on a trailer and took it to them.  He said he would be glade 
to do it because it was something different. It only cost me $350 and 
everything fit. It was not stainless and I did have it wrapped and it lasted 
quit a long time.

I was going to build it out of 321 stainless until I checked the prices. 
  A 321 U-bend is $94, a 304 U-bend is $40, and a mild steel U-bend is 
$10.  I need 8 U-bends (four are actually J-bends, but same price), just 
to think about getting started, we're talking $800, not to mention 
collector, tailpipe, flanges, etc, if built from 321 stainless.  The 
existing one made it to 600 hours and was mild steel.  I'll have N56ML 
back in the air before I put another 600 hours on this one!

By contrast, my Corvair system was almost reasonable built from 321, 
because it is built so simply using only three U-bends for six 
cylinders.  But it's not a complex 6-into-1 system either, just a pair 
of simple 3-into-1 pipes.

I have everything I need to start on it, and that's what I'm doing all 
weekend, and probably next weekend as well.  I built two mockup engines, 
one with the old exhaust to measure distances and angles from, and the 
other as the fixture to build the new system onto. We'll see how it goes.

One thing I learned along the way is that Great Plains has no exhaust 
systems built, but they do have fixtures, so they are "to order" with a 
30 day lead time.  The configurations are shown on their website at
http://greatplainsas.com/scexhaust.html , none of which are similar to 
mine.  Also, gauge size is not mentioned on their website, but they are 
18g (.049"), rather than the 16g (.065")like the original exhaust 
system, so I had to get all materials elsewhere.  I did buy flanges from 
them, but am not enamored with them as the mounting holes are huge 
compared to the 8mm studs, so I'll have to carefully center the flanges 
to the ports before I start welding tubes to them.

Re: KR> Melting lead

2017-01-28 Thread Lawrence Bell via KRnet
Tin can, fishing weights, wheel weights, propane stove, torch, it's all
good. I found the led does not stick to aluminum so I took a u channel to
form the sides and a thin piece of aluminum that I shaped to form the front
and back and fit it in the u channel. I taped the outside which will burn
but it hold the led long enough to form a nice weight.

Re: KR> Melting lead

 I feel like I cheated... I borrowed a lead melting kit from one of my plumbing 
contractors. If i remember correctly it was a small cast iron laddle with a 
pour lip on top of a stand of some sort with a propane torch with a larger 
flame head underneath. It only took several minutes to get it melted and ready 
to pour. FYI- I built the molds out of wood for my counter weights but with the 
burning you are only going to get 2 uses out of the mold which should be enough 
as I only used 2 counter weights for the alirons and  pieces for the counter 
balance of the elevator.

I melted mine on a small standalone hot plate (so I could do it 
outside).  The pot was a thin one with a lid, and it did take a long 
time, but it worked.  This hot pad is a cheapo thing that's probably 50 
years old, with a simple coil of nichrome wire in a spiral shape down in 
a piece of ceramic plate.  I would think a gas stove should do the job...

》what your wife considers an old pot is. 》Be forewarned.
When it comes to the pan I learned the hard way.  I was interrogated after the 
led melting operation had begun.  We needed a new pan anyway.  
My fishing weights melted just fine on the stove but I haven't been fishing 
since.  I also used the led weights for pinewood derby racing that can be 
purchased online or at the boy scout store.
