Thread: a rat in the house!
25/09/2017 11:56:09

Went to our local Brewers Fayre for lunch one day and as I parked the car saw something quite large ( first impression was a cat) walking across the car park towards the kitchen area of the building, second take and it was a very large rat totally oblivious of everything going on around him. Problem is that rats are everywhere nowadays, worst source of problems is if anyone keeps chickens, they are a rat magnet.

Thread: Design conundrum - fitting a new workshop into a space
25/09/2017 11:44:42

Tony, when I built my workshop it is in the corner of the garden with two fences adjacent, one along the back wall which is 17 feet long and the other along the side about 7 feet long, the walls against the fences are built from concrete block, the two walls not adjacent to fences are concrete block for the 7 feet one and the front which has the door and window and is 17 feet long, is constructed of wooden ship lap on the outside with 100 mm of celotex and the inner layer is OSB, (oriented strand board). The front wall which is wood framed with the ship lap cladding stands on one row of concrete blocks, this is to keep it above any water and damp which prevents or at least dramatically slows any rotting of the base timbers. The interior floor is concrete which has been painted with polyurethane floor paint. The roof is a flat construction of OSB laid on suitable joists and finished with two layers of " torch on" felt. Inside the roof is insulated with 50 mm of celotex fitted between the joists. During the winter I run a built in dehumidifier which runs at night on off peak electric, there is also a small oil filled radiator running on low setting throughout the winter months and ensures that the temperature remains at a constant 10 degrees C. The insulation in the roof and front wall means that temperatures with the heating remain fairly constant and therefore the variations which can cause condensation are avoided and the equipment remains rust free ( well has been to date). The window fitted in the front wall is a large double glazed unit which was diverted on it's way to the dump so cost nothing, well worth searching out double glazed Windows to fit as they will enhance any insulation measures taken. You can't insulate enough, it will all contribute to eradicating any rust problems from condensation. Three of my walls are concrete block which some people advise will promote condensation, I have no problems with them but then the area the building is located in is relatively sheltered from extreme weather and in another location may behave completely differently. Build as big and as substantially as you can afford you will not regret it.

Charadam I think I still have a packet in my workshop from 50 years ago, how time flies.

Dave

Charadam you are right purple used to denote hiduminium, but I am going back 50 years when I first joined the airforce and was repairing aircraft, it is more than likely that identification standards have changed with the passing of time.

Thread: Bench Vice
11/09/2017 19:38:02

I was lucky enough to inherit my fathers four inch Record vice when he passed away, it doesn't have quick release but was in as new condition because during his latter years he fitted it on his workbench but never used it. My advice is go for a Record if you can afford it, new or good secondhand, you won't regret it.

Thread: Help me choose a lathe to suit my hobby
11/09/2017 19:29:19

About ten years ago I bought a Warco lathe, the BV20 which has a geared headstock, I chose this model because I was wary of an electronic speed control having heard some horror stories about the fragility of speed control boards, fortunately these components appear to be much more robust nowadays. The BV20 has six speeds through the integral geared headstock, the only drawback was the noise from the gears, I mentioned this on a visit to Warco when the twelve month warranty was nearly expired and without question they arranged to exchange the lathe at no cost. Unfortunately the noise level on the exchange machine was only marginally better, ear defenders do help to attenuate it. I checked the gears in the headstock and it would appear the noise comes from excess backlash between the meshing gears, it would appear that if the shaft centre distances are correct then there are problems with PCD of the gears as produced. The lathe is a Chinese machine built to a budget and consequently you don't get hardened ground gears within that budget so I live with it. In the ten years that I have owned it I have only replaced a faulty NVR switch which failed after about seven years, during this time the lathe has done everything asked of it, albeit a bit noisily. I cannot fault Warco for their service and wouldn't hesitate to recommend them, you have to remember though that Chinese machines are built to budget and are not Myfords or Rolls Royces but they enable a lot of us to pursue our chosen hobbies for a very modest outlay.

Thread: Twisting brass wire
07/09/2017 17:17:34

No Gordon your right never did.

Dave

06/09/2017 18:51:54

Gordon are you sure it was brass wire that you used for wire locking the aircraft components as the standard for aircraft work was non corodible steel wire (I.e. Stainless) and it was very tough but easy to twist when using locking wire pliers, 22 years in Aircraft work equals an awful lot of wire locking.

Thread: New Moore & Wright any good?
28/08/2017 19:59:18

I have a budget line M&W metal calliper, can't fault it, very smooth action. Are some members experiencing M&W clones, could that be the problem.

With four blokes on bicycles cycling to work I would be more worried about their output of methane on the environment.

Thread: Metric vs Imperial - Practical or Traditional?
26/08/2017 14:26:01

I think I remember reading somewhere that America (I.e. USA) was the first country to officially adopt the metre standard and that was in the 1870's or 1880's; suffice to say their progress towards full metrification has been a little slow!!!

Brian, a firm called Walker Midgely provide workshop insurance specifically for model engineers, you can select various options to build the schedule that fits your circumstances.

Thread: Motorising the Z axis on a Chester Champion 20V Mill
20/08/2017 15:24:26

Geoff, many thanks for the photo of your conversion, your mill does look identical to mine, the stepper motor looks very sturdily mounted and could be a way forward.

Ian, your conversion looks very practical and simple, again another avenue to explore.

Many thanks to you both. Dave

20/08/2017 11:08:19

Thanks Ian your posting came in while replying to George, will research "power feed" and see what surfaces.

Dave

20/08/2017 11:05:54

Thanks George , my sympathies I know how you feel. A gas strut would certainly help with my problems, or perhaps a pulley system, hopefully someone in our engineering fraternity will have some proven ideas to share with us.

Dave

19/08/2017 22:20:30

Due to progressive spinal problems and paralysis developing on my right side I am finding it more and more difficult to raise and lower the head on my Chester Champion 20 V Mill, I wonder has anyone motorised this function and if so would they be able to share their experience and detail the method and components used. Thankful for any help and information.

Thread: What Did You Do Today (2017)
19/08/2017 18:17:57

John you certainly won't regret it if and when you commit to a Mac, I did so in 2011 because of frustration with Microsoft, like Norman I use Word for Mac which means I keep connectivity with all my old documents. Same experience as Norman, crisp and speedy setup and no problems since I converted, expensive to change to Mac but well worth it.

Clive if I lived closer to you I would be in your customer base for honey. Can't beat proper English honey as against some of the Rubbish that they label as honey in the supermarkets. I am sure that you will have no trouble finding customers.

Condolences Neil, we have always had cats, five at the moment, hurts terribly when we lose one, they are truly members of our family. Three grown up daughters, left home long time ago, they all maintain that the wife and I think more of the cats than them, not true we love them all equally.
