Spent this morning changing out shorted oven element ...

Oven element.jpg

Damage at top left don't ask what caused it... no power cut, it didn't trip any breakers, just stopped working, Oven not heating, but fan still worked & thermostat light on so that's working, I deduced that the element had gone, ordered new one from espares ( Usual disclaimer ) yesterday, arrived today... Fitted working fine, job done. the only downer was I now have an aching back, set off my spinal arthritis, bummer!.

Thread: Barrier Creams

Try..

Deb Stokoderm Protect Pure Barrier Cream 100ml - Machine Mart - Machine Mart

I use this every time I'm in the man cave. I use a 100 ml squirty bottle to dispense a small amount onto the palm of my hand & rub it in fairly vigorously, it dries quite quickly leaving no sticky residue & is easily washed off with soapy water, & economical. Usual disclaimer applies.

Thread: Domestic water hammer
24/03/2021 13:28:54

FWIW; It is possible that the ball valve float in the tank was 'bobbing up & down ' due to water rippling/splashing as it refilled causing the plunger to quickly push/pull the valve itself to open & close rapidly causing the banging.. sharp on/off of water flow which obviously disappeared as it levelled off & settled down.

Denture tablets work well for me; boil some water, pour into container, add spoons + one tablet, & leave until fizzing stops + 10 mins or so then wash /rinse. Works well on stained plastic too.

Thread: Mail Scam

I got one yesterday from the president of the USA advising me that the FBI had discovered a scam had been perpetrated against me & that I was entitled to a refund of 5.5 million dollars for pushing a few buttons, I thought that sounded a bit suspicious.

BobH

I've had this one too last month. I've also had various mails stating I have an inheritance from a long lost family member from dept in a co.in Singapore, I did a bit of research on this co.& it was a genuine co. so I emailed a copy of the mail to their customer contact mail naming the sender with a request to check their staff listing, Never heard from either again.

Also had mails from agencies / lotteries in Europe, where they asked for all the usual details to pay the winnings into, needless to say no details were/are passed on. I know who I deal with via mails etc, which is only a short list so anything else that arrives gets checked via my Internet security programme which displays a ' possible scam' notification on my screen.

I've also had the usual Royal Mail / Parcel force, et al, scam to pay for a redeliveries.

Thread: Finish for wooden base
23/03/2021 11:11:41

I tend to keep finishes as simple as possible; I sand down the wood, wipe off, apply dark oak stain in a couple of coats to achieve the depth I like, with a rub down using fine grade emery foam pads in between each coat, once I achieve a decent look I then use a couple of coats of clear lacquer spray ( car body lacquer ) for final coating.

Continued on with pieces for my Scotch yoke engine; did the piston rod & piston. A note to others FWIW, after careful reading of the dwg I decided to make the piston in two peices, why you ask?.. well the piston OD is 26mm, the undercut for the pistonring is 19 mm, the ring is to be made from Nylon or PTFE , now tell me how to fit a 19 mm ID over a 26 mm OD without splitting the ring, with the correct gap, to ensure a seal.

I decided to machine the piston as per dwg but machining the outer/top part as a seperate flat plate. As the piston assembly is tapped M5 it all screws together to become one unit with the ring captive. Will take pics later.

The button oiler makes me think it may not be for the food industry. Just a thought.

I believe there is a silicon food grade lubricant on the market ?

Would the continually changing surface speed when facing have any influence?

More than likely; as I understand it is to do with surface speed, the nearer to the center of the work you get you have to increase the RPM to keep the surface speed constant.

Thread: That little elf under the workbench again
18/03/2021 12:43:48

... 'However, for small parts (that I can't immediately see) I now use a magnetic 'tool holder'

Same here; I have one of those magnetic trays that have two large ferrite magnets bonded to the underside, iirc I got it from a trader at one of those country house steam rallies a couple of years ago. I use it as IanT does, for any small disassembly screws that are too big for my stubby fingers to grip.

John Stevenson sharpened some end mills, at a show, for me, in a matter of minutes.

Didn't stop me being careless.

Just wish that I could justify the cost of such a useful machine!
