Can a panhead be a reliable motor?
a stock pan can be pretty reliable, but if they over heat because of running lean from an unnoticed intake leak or anything else that makes them run hot. they can crack a head. that's why you see so many pans running around with shovel heads on them. if your looking at original pans make sure the hydraulic PUSH RODS have been replaced with hydraulic LIFTERS or solids.not much chance any hydraulic push rods are still around but you never know. shovel heads seldom crack but they usually weep a little oil here & there. an evo would probably be your most trouble free bet, but they dont have as much soul as pans, if that matters to ya. if your buying a new earlier style engine a 93 inch S&S shovel would be hard to beat if you can stand the price of admission..
Approximately how many bags of cement are required for a 1500 square foot house?
Here’s a quick thumb rule for calculating concrete slabs by the square foot.Most all slabs around residences are 4″ thick. Driveways sidewalks, patios and garage floors and other interior slabs are all 4 inches thick.When you buy concrete delivered in a truck to your site you’ll be charged for the volume. They sell it by the cubic yard. One cubic yard will cover 80 square feet of 4” floor.To find out how many cubic yards you need, divide 1500 sqft by 80 sqft (81 to be exact). The answer 18.5 cubic yards for just the 4″ slab floor, the support footings have to be calculated too.If your house is a slab-on-grade design then the slab will need footings under the floor. The building slab needs additional support under all the exterior walls and load supporting walls. Without support the 4″ slab will break because the house weighs so much and those loads get concentrated into small areas, hence the footings under the slab floor.Sometimes there’s almost as much concrete within the footings as in the 4” floor. But you’ll need to calculate the size of the footings to see how many cubic yards for those in addition to the floor volume to get a total.A house this size will need about 3 to 4 cubic yards of concrete for footings but without a set of plans this is just SWAG engineering. You’ll need a few hundred feet of reinforcing bars too.Some standard sizes for footings are 8″hgt x 16″ wide, and 10″x20″ or 12″hgt x 24″ wide″. Just multiply the hgt by width by the length to find out the volume of the support footings. Remember there are 27 cu ft in one cubic yard, and inches will have to be converted to feet. The building plans will call out the sizes and placement of all the footings and you can use those as a guide for your calculations.I really can’t answer your cement bag question because I’m not sure if you are asking about the specific amount of cement used in a Concrete mix or you want to know how many bags of redi mix concrete it would take to do your house. But if you are going to Home Depot for the redi mix stuff you’ll need about 960 bags, the 80 lb bags.
How can I tell if my solder is acid or rosin core?
I have a little Radio Shack soldering set, and it comes with a small spiral of solder. However, it doesn't specify if the solder is acid or rosin. From what I've read about soldering, it seems acid core is something you'd use for soldering dirty metals, which makes me think it's something you'd buy separately, rather than it be included in a tool kit. Am I correct?
Where do you check the oil on a S&S 96 motorcyle engine? Also what should the normal oil pressure be?
You don't check the ENGINE for oil......you check the oil tank. And HOW you check it depends on the bike itself, different tanks have different levels and procedures for checking the oil level. The 20psi.....is that at idle or higher rpms? If the 20psi is at idle, it's fine, very good in fact. You should read anywhere between 40-60 at higher rpms. Add and edit to your question giving more details on the bike and what rpms you see the 20 psi. I can help you more from there. S&S certified tech. EDIT: Don't discredit Choppy and Polarbear...they know a good deal about these bikes as well, we are all kinda old school here, sometimes it bugs us a little when people don't know the basics....lol. I've gone off on people myself. Describe your oil tank, or even better, if you have a pic of the bike that you can upload and send a link for it or email it to me, I can tell you how to properly check the oil level. At normal operating temp, (about a 5mile ride), 10psi oil pressure sounds normal, check your pressure while riding at about 60mph, anything 40-60 is great.
Is there any benefit to having a higher hemoglobin level, within normal limits?
Thanks for the A2A, Karen.Short answer: yes, but it’s minor.The more haemoglobin you have, the better your blood carries oxygen. So far, it’s a win. But too much haemoglobin makes blood too viscous: it’s harder for the heart to pump, and it doesn’t perfuse well through capillaries. It’s also prone to pathological clotting, causing venous thrombosis and the like.But this wasn’t your question: you specified “within normal limits”.The only evidence I have for a higher haemoglobin level comes from patients who undergo surgery. We have rock solid evidence that the better your haemoglobin level before surgery (within normal limits), the better you do afterward. Your recovery is quicker and you have fewer complications.Some of this is due to the fact that people tend to bleed during surgery. If you start off with a full tank, and you lose a bit, you’re still ok. If your tank is half empty, you can’t afford to lose any at all.Some of this is due to the realisation that blood transfusion is not harmless but causes problems (such as immunosuppression). So just transfusing blood into people isn’t the answer.Some of this is due to the fact that a robust haemoglobin level isn’t an end in itself but is an indicator of a subject who is healthy and well-nourished and takes exercise, and is therefore likely to handle surgical stress better.For people not having surgery, I think it’s this last thing that matters. A high-normal haemoglobin is an indicator that the person has good general health, and a good diet. A healthy bone marrow implies a healthy immune system. And since exercise boosts haemoglobin production, it’s also a sign of good physical fitness.Such a person is likely to be less susceptible to illness and have good reserves to fight it off.However, I don’t know if actual studies have shown this. There are, however, a multitude of studies which show the other way: anaemic people do worse in illness, cancer, surgery and so on.
