Having worked on plating lines the two pictures show a before and after use, and illustrates how It corrodes. So salt on a car will fair just as badly, it looks really good when done but seems brittle and allows water to get in
Worse thing I have found is that I worked in engineering 47 years first 5 years as a machinist then a fitter, rest of time as Design Draughtsman. Problem came when I retired, then firm went bust and management changed, all my life Turning or milling I could get done for nothing (was called...
Think you will find its 70 for a car on a dual carriage way without trailer, Speed awareness course victim plus 3 points from last year, but hey I am an old reckless driver.
Yes that's correct they fit in the parallel bore of the turret of a Capstan Lathe cut miles of thread using those, a hell of a lot quick than single point threading. Interesting picture of the large tapping version never seen one of those in the flesh.
Like you only longer had used a Buzz box AC, then more recently bought an Inverter DC stick welder with hot start, so much easier. All that hard work with the buzz box made it easier for you , try going the other way round ie DC inverter to buzz box.
I use Screwfix a lot and order on line (Click & Collect) you always have to have your card that you paid with, put in the machine and verify pin to confirm its you. Most of the time its quite quick, the bit I don't like is you have to join the queue and wait for some so called tradesmen who get...
I got 8/10 its 45year since I worked a machine tool in anger, the same things hold true today as then, Negative rake carbide tip need rigid machine loads of HP/KW. High speed steel tools half decent sharpened and away you go.
Parting off I thought was a black art until they put me on a Ward...
I worked a Denhome Centre Lathe in the 60's and it had a rear attachment that took a morse taper drill, you just wound cross slide back out of the way, and then pulled attachment up to fixed stop. You used power feed when drilling, always remember coming home and telling my dad I had been...
Spent my whole life design around those type of bearings, the standard type is fitted with two allen grub screws. If you intend to use on a plain shaft then remove allen screw and dimple shaft with drill point, and then
refit allen screw one at a time with Loctite.
The expensive way is to have...
Yes agreed it was usually the two holes in the top that block with underseal when left a while. Always cleaned holes with welding wire every time before spraying. Also used to dip pick up tube in jar of thinners and pull trigger to clean nozzle out, as that could block also. If you didn't do...
We used to use one of those things to drill 3/4" diameter holes in machine frames at work in the 1960's . We had a sold bar slid in the handle about 2 foot long, with an instruction if you let got then you were sacked. Of course in those days men were men and woman were glad of that fact. Those...
