Thread: Vice - again
05/04/2022 14:07:16
Posted by John Hinkley on 05/04/2022 11:28:30:

I don't know what mill you have but unless it's a Bridgeport-size one, a 6" vice is going to be too big. When I bought my Warco VMC mill, I ordered the large SG versatile vice from ArcEuroTrade. The courier warned me it was heavy when he delivered it. He wasn't wrong - I had difficulty lifting it onto the table. A quick 'phone call and a half-day trip to Leicestershire later and I had the 100mm mounted. Much better.

Googling the Accu vice throws up one from Axminster Tools, but that one has a rotating base. I suggest that this will rarely, if ever, be used and will seriously decrease headroom above the vice. I'd advise a purchase from Arc - you won't be disappointed.

John

It is indeed Bridgeport size, check Colin's albums

Thread: Dulling the shine on a stainless steel ball

I dripped a spot of Harpic 100% Limescale remover on a stainless steel knife. Next day there was a neat matt finished mark. It even says on the container not to use it on stainless steel.

Try dropping your balls in some of that.

This might sting a little.

It would be worth removing the display box circuit board to check for any cracks in the track around the base of the components. Pay close attention to the larger items and also the flexible ribbon to the display if there is one.

Free machining steel comes with free electricity vouchers.

Given the cost of power these days the lantern tool post or better still an original Victorian candle tool post if you can find one could save you a great deal of money.

Thread: Repairing a Myford 4 jaw chuck.

Interesting. How else should one unscrew a M-B 4 jaw chuck other than using the chuck key in the screw sockets ? I bougtht mine in 1966 second hand with the lathe and have always used this method without apparent detriment. Screws show all the signs of being steel, sockets are hex. though.

The issues start when someone belts the chuck key with a hammer.

Have you tried RDG ?

Thread: Pressurised vs loft tank CH systems?
20/03/2022 14:27:20
Posted by SillyOldDuffer on 20/03/2022 14:16:53:

I asked this very question before my son's house was fitted last year. No mention of building regs, but pressurised boilers can be installed anywhere in the house because there's no need for a header tank high enough to provide hot water pressure, and hot water runs quickly because it's pretty close to mains pressure.

Couple of painful incidents in my parents house put me off loft tanks : first a dead pigeon, and then a major leak about ten years later which started while they were asleep!

Dave

UG! Tanks are plastic and have lids now for both those reasons. My father had Bees block the overflow on the hot tank back in 1960, then the washer went.

You get more choice of mixer taps that work.

You only heat what water you need

You, um, er, give me time now ........

You need a bigger gas feed right back to the meter

You get enough hot to feed one tap only.

You get a condensate drain that freezes if the outside temp is lower than -8C for more than a day and stops the boiler. Particular fun when the boiler is in the roof space so that freezes as well

You need one of these fairly greedy with thin air tool oil, but much better with thicker car engine oil. Or you could make a proper oil pump such as the on on Minnie.

Thread: Damp shed: what’s the best way to add ventilation?

What did you 'seal' the roof with? It should have been heavy duty felt, the expensive stuff. 6x4 sheds tend to be made cheap with the thin felt and thin walls made from fencing panel timber.

Without gutters rain will run off the roof hit the patio and bounce up wetting the walls.

It’s tongue and groove panels but the felt is thin and poor and nailed on which I’ve had to paint tar over.

I think my big mistake was painting the inside of the shed in white emulsion because the moisture can’t absorb into the wood and evaporate to the outside due to the paint layer and so it just condenses. The outside is also painted but with Cuprinol.

Simon,

There's nothing wrong with nailed on felt

Spend the £42 at B&Q and get some decent 15year felt, rip the old felt off, I think you will find a wet roof under it which will need to dry in the sun for several days. There's so much movement in a wooden building + the thin felt moves as well, it's impossible for that felt paint to work for more than a week.

You'll find the brackets can deform enough to take out any slop when you tighten the bolts.

Having watched the RedBull soapbox races the major flaws are wheels collapsing under side load and nor enough steering and or brakes.

Oh and doing a rubbish dance at the start.

Better, surely, for us to decide for ourselves what we consider tasteful or otherwise, and to act accordingly, than to have others decide for us and legislate, or apply mob rule.

Edited By Kiwi Bloke on 14/03/2022 07:41:25

But 'us' left alone are the mob as we had on here last week.

Thread: Pacemakers

Blimey, I hope they made the pacemakers better than some of the 60's motorcycle electrics!

( light hearted comment not intended to start a huge thread about motorcycle electrics, after all Joe Lucas was known as the prince of darkness!)

Dave

Pacemakers never went anywhere near a Lucas factory, they came out of a proper lab and the only thing that Lucas were allowed to manufacture on the site

I always thought that was when the battery fell out (after the headlight flashed very bright for 1/2 second)

10/03/2022 16:20:19

Talking of pacemakers, the originals were made in the 60's at Joseph Lucas Research in Shirley, they tore the building down this week I believe to add more capacity to the local care home ghetto

Calor gas cylinders can be found quite cheaply at car boot sales and the like, don’t worry about size or condition once you have the cylinder you just swap it with the size you prefer at your local calor dealer.

Those were the days, now you need to check the Calor web site.

Some torches need a particular size of bottle to work properly.
