Lou Schneider Posted January 20 Report Share Posted January 20 (edited) Once I bought new tires for my Ford F-350 and the shop inflated them to the full sidewall pressure which was 50% above the pressure on the truck's placard. It was a 60 mile drive home (unloaded) and the truck felt very unstable, like it was sliding and fishtailing. I almost brought them back the next day but I caught the error and setting them to the correct pressures solved the problem.

rickeieio Posted January 29 Author Report Share Posted January 29 Yep. Take the sidewall pressure and the door jamb sticker both as guidelines, but not an absolute. In the case of my f-150, I need to run 48 psi for the load per tire as shown on a scale and the tire manufacturers chart. Door sticker calls for 36 psi. That may work for an empty truck, but I have a bed mat, optional big fuel tank, cross box, and several hundred pounds of tools and "stuff". Next "myth".... never drag a file or hacksaw backwards across the work material?

Danfreda1 Posted January 29 Report Share Posted January 29 True but you don’t need to completely lift it off the material being filed or cut. Easy with a file to lift but on the backstroke just lift up on the pressure Quote Link to comment Share on other sites More sharing options...
Deezl Smoke Posted January 30 Report Share Posted January 30 (edited) Fireball tool made a video about 2 years ago using an old shaper to test the old file backwards myth. Normally I'd post a link, but I can't seem to get the video to play on youtube. It just opens then goes white screen. But if you search youtube for fireball tool file, it should come up. It was a very interesting video. I'll not spoil the results, you'll have to watch it.😉 Ok, it was my computer. I got it to play. So here's the link.

rickeieio Posted January 30 Author Report Share Posted January 30 Back in the day, we had a power hacksaw in the shop. Like a chop saw, but with a big reciprocating blade, oiler dripping on it. Those blades lasted forever, even though they were dragged back every cycle with the full weight of that support arm. Oil made the difference. Also, if you look up filing machines, there's a lot of different variations, some quite large. None reduce pressure on the return stroke.

Danfreda1 Posted January 30 Report Share Posted January 30 Not all Rick, we had some in different shops (hacksaw type saw) that lifted a very small amount. Maybe not enough to see but it you put a trained finger on it you could feel. Most of our saws were the horizontal bandsaws with at least a 1 inch blade Quote Link to comment Share on other sites More sharing options...

Our jack-xxx saw in the shop had a cam that slightly lifted the blade for the return stroke. Our blades didn't last long sawing the brake-die steel to length. It arrived already heat-treated to RC20. But with mild steel you're right the blades lasted a long time. Edited February 1 by Ray,IN Quote 2000 Winnebago Ultimate Freedom USQ40JD, ISC 8.3 Cummins 350, Spartan MM Chassis.

Sorta....I've tried it, and it helps. Not like new, but much better than they were. But, I'll say, I was trying to revive files that had been wet, and rusted. The vinegar took off most of the rust, so the file seemed better. There are better ways to remove rust.

The vinegar method is very old, long before Naval Jelly and like chemicals were invented. Left exposed to vinegar "fumes' long enough, it does actually erode the teeth enough on the tips to sharpen them.

So I was told, the teeth are eaten away by vinegar, since the teeth tips are the thinnest part, they are "sharpened". I have no empirical evidence to support that though. Georgiahybrid, I'd forgotten about that technique to reduce clogging with soft metal.

rickeieio Posted February 1 Author Report Share Posted February 1 Naval Jelly is phosphoric acid in a jell form. Same acid as in Coke. You can buy it dry too. Works great to remove rust. Ever heard about dropping a nail in a can of Coke, and the next day it's dissolved?

Ray,IN Posted February 3 Report Share Posted February 3 The nail, no, but I have heard of placing a 1" cube of meat in a coke and a few days later there is a greasy film on top of the coke, but no meat left. The original Coke/Coca Cola contained cocaine, I've seen a gallon jug of coke from perhaps a century ago and the label listed the ingredients.

rickeieio Posted February 17 Author Report Share Posted February 17 Right...... Our old ISX made 480 ponies at the ground. Our new-to-us PACCAR is rated 455 at the crank, but more torque at 1,100-1450 rpm. I like this kinda torque.

I haven't driven enough new stuff to be sure, but it seems the newer motors are making more torque, but keeping the rpm lower, thus the great pulling power with low hp figures.

Been there, done that, got the tee shirt. The rig in my avitar was a 6.2L that I later swapped out for a 454cid. Easiest swap ever. 3 line fuel pump, ignition power to the coil, and homemade radiator hoses. Throttle cable, just a simple part swap. The torque converter on the 6.2 has different perimeters, but still works. The 6.2 has a vacuum pump to operate the trans and hvac, so simple to plumb that hose in the manifold on the 454.
