Thread: Why is my silver steel undersize
18/01/2020 18:33:25

Have you measured the finished size of your reamed hole, or are you assuming it's 5.00mm?

Thread: Watch servicing
05/01/2020 13:09:15

You may not know that there is an ongoing court case between Swiss watch manufactures who are restricting the supply of spare watch parts and Cousins Material House who supply watch parts to repairers in this and other countries.

This is making it much more difficult, if not impossible for the lone repairer, to carry on business and hence the "big boys" can increase their prices.

Thread: Bulking problem?

How about trying a number of ratchet straps.

Thread: Learning CAD with Alibre Atom3D

Thank you for your prompt replies gents. Problem solved, as Jason suggested by setting the "sketches toggle"

Now on to the next part with renewed vigour!

I am just starting the base component of the Mini Gauge.When clicking on the blue part icon the work space opens but the three planes do not appear.

The XY plane was selected using the design explorer.

2D sketch was selected and the circle drawn and sized.

2D sketch was deactivated and the circle just drawn disappeared.

It would appear that maybe a global setting is incorrect.

Can you help please?

Thanks

Alan

Doubleboost has recently had a series of videos on his website of different dti's being dismantled and serviced.

Thread: ASEA Motor Wiring

The following link is primarily for refrigerators, but does indicate the the circle symbol is an overload protector.

Careful inspection of diagram 14-43 indicates motor terminals as P R and S.

The start relay coil appears to be in parallel with the motor starting winding, rather than in series as suggested earlier.

Just a thought, are you sure the thread on the screw being tried in the hole is true?

Thread: Alternative source of industrial drawer cabinets?
25/11/2017 22:19:02

Have a look on the IKEA site and search for HELMER. 6 drawer self assembly painted steel cabinet. I've got one and it's handy for small tools. £30.

Thread: My first foray into clock repair
22/11/2017 15:09:32

Russell mentioned above that the pallets need oiling. However, the wheel and pinion teeth are intended to run without oil.

When you get the movement to run you will find, in all probability, that the strike will not be correct. that is, the number of strikes will not agree with the hour hand. This is because this movement has a locking plate striking system. Correction is easily carried out by moving the minute hand until the striking has taken place and then operating the strike manually, generally by depressing a lever on the side, until the correct hour has stuck. Hope this helps.

Thread: Contrate wheel

Cheryl,

Could try J Malcolm Wild for the replacement contrate wheel.

A search will find his website.

Thread: What would you ban and why? (Definitely tearoom!)
22/08/2016 07:42:12

Random amounts of extra time in football matches. Stopping the clock during breaks in play would be fairer.

I hasten to add that I am not a football follower.

Thread: Three cornered Philips type screwdriver
21/12/2015 23:16:04

Brian,

I have made one which is perfectly satisfactory for the odd screw which needs to be shifted.

Nothing more than a piece of silver steel filed with a triangular taper at the end to fit the recess in the screw. If it is the sort with a security pin in the centre then drill a small clearance hole in the end.

Harden and temper if you need to use it several times.

Thread: Drawing Projections
11/05/2015 14:50:28

One of the reasons that CM are more popular than MM is because in school maths lessons CM are almost always used in examples and questions about measuring. Check out any primary or junior maths book for examples.

CM are also more understandable for youngsters in that they can easily see that 3cm is longer than 2cm, whereas if mm were used the difference is less obvious when drawn.

Thread: Sandown photos and thoughts on the show

Hi Neil,

I was there on Friday and just about heard the announcement about your meeting. The instructions were to take the lift to the second floor at 2.30pm. I did just this, but no one was able to tell me if the meeting had taken place or was even going to take place.

Thinking back, the announcement may have said 12.30, because it did seem sometime ahead of when the meeting should have taken place.

Thread: Screwdriver Magnetiser/Demagnetiser
01/11/2014 22:41:20

My demagnetiser is the stator from a domestic washing machine pump. The impeller had failed and the pump was replaced.

In use the coil is energised by the mains supply with the item to be demagnetised held in the magnetic field; the item is then slowly withdrawn from the field before the electricity supply is switched off.

Of course precautions must be taken to prevent contact with the live coil windings whilst carrying out this operation. Enclosing the stator in a nonconductive box with a hole to allow the item to be operated on would seem sensible.

Thread: Did you make one of these at school or as an apprentice?
01/11/2014 21:08:09

I have just completed a version of this engine which was published in Engineering in Miniature Nov 2011 - Feb 2012. It was my first and only hot air engine and I'm pleased to report that it ran at the first firing with a spirit lamp.

I wonder, do those who do some of the grinding on the side of the wheel also dress it on the side?
