Thread: Stirling regulator stuck
16/02/2022 20:07:52

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.

Thread: Motor protection
03/02/2022 17:14:41

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.

Thread: Three phase reversing
15/01/2022 22:06:27

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

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

Thread: joy valve gear (Derby 4f)
10/09/2021 20:19:45

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

Thread: Electric motor speed

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

Thread: Gas Burners for boiler
31/08/2021 20:58:33

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

Thread: Overheated Drill

Builders I have spoken to don't expect even quite expensive drills to last much more than a year or two.

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.

Thread: Injector LBSC type
26/05/2021 18:10:19
Posted by Speedy Builder5 on 26/05/2021 12:50:26:

I am under way in making one of LBSC's injectors for a 5" SPEEDY loco.

It seemed a simpler idea once the body was made to make what was described as a "Slotted Cone" for the combining cone. as detailed in the attached drawing.

Can someone explain what the slots in the sides of the cone do and should those slots pierce the Venturi which passes through the cone?

injectordetails.jpgDAG Brown's book on injectors explains it all very well

Check the function and condition of the centrifugal switch if fitted

If that was down my way, I think most of those poles would be long gone by now, and the cable with them.

You see, we have what are called "Travellers" over here, who can and do remove anything which is not nailed down, and even then ! Helps to tidy up the place, sort of !

Larry it sounds if you in South Africa somewhere.

Leave well enough alone, if there is a nylon or bronze wad between the locking screw/s and inner surface i think that will suffice.

Thread: Safety Switch Wiring

Check if the coil voltage is for 380 or 220 volt, that may be your problem.

While you are about it, why not make an extra shaft, then you can be sure that the first one you fitted will last forever.

Such cynicism I expect from the young, not someone signing themselves as OLD Mart! 😂😂

The "OLD" in Old Mart means he spoke of a lifetime experience wink

Very nice and enjoyable machine but you will be buying tooling and things ..but wait until you see what comes with it.

Thread: What to do when you lose something

What is ones chance of finding a way to stop small items falling on your foot and always find itself under a machine or table ? I decided one day to remove the work bench and clean the workshop, the list of long gone things will be several pages!
