    sacrificial anodes

    Zinc anodes are used to protect alu., iron, copper, & brass on boats in salt water. They come in MANY shapes & sizes. Many with threads for mounting. Everything needs to be grounded/bonded for proper protection. Good Luck!

    Refueling fires Why?

    One thing that you don't need to be stupid to do is to fill a plastic fuel can that has been sliding around in a bed liner, without removing it from the truck. Bed liners now come with a warning, but what about when someone purchases a used truck?

    Cracked weld puzzler

    I agree with pre-heating and full welding as posted above, but it sounds as if these teeth may need to be replaced periodicly? One solution may be to roll mild steel to form a collar of sufficient width (say 7"), weld it to the pipe, then weld your 2.5" wide collars to it. You may need...

    how to convert rotary motion to lin

    Any crank, cam, or ellipse will not yeild a consistent linear movement per. degree of rotation. A screw for this application would need a pitch of 51.42857142875... mm., an infinitive number.

    how to convert rotary motion to lin

    Could you use a rack & pinion setup? If so then the pinion needs to have a pitch dia. of 8.1900mm.

    350smbk th400

    The cross member, drive shaft, & rear gears need to be changed. The shifter cable & kickdown cables need to be slightly modified. The exaust hanger @ the cat will not fit but can be fudged. You'll need to find a vacuum sorce for the modulator. You may need to drill to mount the cross member...

    Cold Start problems - Very odd!

    It could likely be the fuel pump relay if the pump only runs after cranking. 'Sounds like when you get oil presure you get fuel.

    Practical determination of machinability

    viktor, There are hardness testing files or portable hardness testers which will tell you the hardness of a material & therefore it's machinability.

    Magnetization

    In order to magnetize screw drivers I simply coil 12 gage wire down the length, then momentarily short the ends of the wire across a 12v automotive battery. You need DC to do this & the wire WILL get hot & melt if connected for too long. I mearly scratch it on the battery terminals.

    Mechanical advantage from pulleys

    With gears or sprockets, simply count the teeth of each gear, then devide. A 10 tooth gear driving a 60 tooth gear wil have a ratio of 6:1. With pullys the pitch diameter must be found & used. If your assembly is not accessible, you can rotate the assy. and count the # of turns of the input...

    Offset synchronisation

    I think that the term you are looking for is helix, ie. helical gear. The helical gear operates more quietly than a straight cut gear, but produces lateral forces or 'thrust'.

    Hybrid Battery Life

    Anyone know what the life expectancy of the batterys in the new hybrid cars is? What kind of enviromental disaster will their disposal cause?

    Crankshaft scrapers

    Womble, rod is correct, get the scrapers as close to the rotating assy. as you can. Slice, fit & form to diameter of the counter weights & throws. The edges should be intrude about 15% into the dia of the rods throw, 20% on the counter weights, & 50% to the main caps. Bolt it to the mains if you...

    Gapless Rings-Opinions

    I've tried gapless rings too, with the same results as posted here. Great cranking pressure & great on a leak down test, but more blowby under operation. I believe this is because air behind the ring needs to breathe, especialy with tight groove clearances. I've stoped gaping rings to the...

    Galvanic corrosion in a fuel tank using stainless to connect aluminum

    In the marine trades we commonly use stainless to fasten alu. The grade of stainless is most important. NICU is the way to go. Alu. by itself will show electrolsis because of impurities, and bonding only helps. Any coatings which don't conduct may lessen the bonding action of the joint. The...
