"My wife's lawnmower" she mows the lawn, how lucky some guys get !!

About thirty years ago the late Basil Palmer gave me a litre of what was marked as "Duraphos" when metals is cleaned and a thin layer is applied with a rag it leaves a dull surface that does not rust. I treat everything prone to rust with it and is also a good primer for painting. I have no idea where this stuff came from or what it is, other that it works

My SPONG & CO works well still probably 80 plus years old!!

You might have problems with difference of expansion steel vs copper. What problem are you experiencing? Leaking and or corrosion?

Try teflon for filing rollers

Could be that the regulator was left shut when last used, try filling boiler with boiling water and that the expansion might free it. Worked once for me. I always make sure that the reg and all valves are open when cooling.Good luck.

I automated my band saw about a year ago for cutting short pieces from bar stock, it was necessary to stop when things go wrong so i installed a system to stop the motor if the driven wheel does not complete a revolution in a preset time (blade brake. slip off or jamming) This work great and i can do other work while the saw carries on.

I revers my lathe by throwing the switch at full speed all the time without any problems. The Herbert preopt turret lathes has a "plugging" switch mounted at the rear of the motor (many people confuses it with a tacho for speed control). This device is driven by the shaft and is arranged so that the motor when running sets up a opposite direction as soon as the motor is stopped through a set of "plugging relays" enabling a quick stop of the motor.This work in both directions. Check schematic drawing for no. 5 and 7 preoptive lathes. The big Herbert drilling machines has a manual reversing switch along with a 4 speed switch and is reversed at any speed without any ill effects. i shall not attempt this with screw on chucks on a lathe, I will post part of the wiring diagram later

Hi Mike as Howard says age, is no barrier I am in my mid 70's as well and as long as one remember what you went to the bathroom for you'r ok still, misplacing (or rather tools going missing while it is in your hand) or don't remember your wife's birthday one can live with that i think.

Another mike

A wonderful achievement, some adventure too well done

I like Macolm's explanation (3)

Where am I (or us)?. slip guages, dro's, sine bars, cnc, qtp's etc etc will take me a lifetime making on of those as someone said in a James Watt like workshop. Good video though

Wanted to build a Derby 4f myself experience difficulties with the drawing some 25 years ago, gave it away and did a Simplex instead. I suspect Don Young's drawings had some incorrect measurements

Commonly called a universal motor, not to be run without load

Hi Matt Stevens, check out my photo album for pics of a round gas burner that i made long ago. i'm using it on my vertical boiler also 6 inch in dia. It is quite easy to make in any size and performs well. pm me if more info needed Regards Mike

Correct. the smaller drills and angle grinders became a consumable item i go through 3 each annually and

bin them, not worth even opening them.

J Bay regretfully is no longer in business as Mr Heydenrych retired about three years ago. Made wonderful stuff for the ME enthusiasts.

Check the function and condition of the centrifugal switch if fitted
