Thread: Magnetism in Stainless steel
01/04/2020 09:08:03

I want to make a set of gimbals for my Sestral compass.The original ones were made in brass, but the main ring is a thin "Z" shaped ( approx 6,15,6 ) I do not know how to form a ring that section. Plus the second part is a semicircular cast piece as a "T", tipped on its side, with a bracket all cast in at mid point, for mounting on a dovetail to the bulkhead.

So I intend to make the first full ring in 304 stainless steel strip rolled into a circle. The second part will be similar but heavier gauge with a 50 *30 *8 mm brass piece either riveted, or silver soldered, to it to form the bracket. Brass as easier to machine a tapered dovetail.

I know that SS304 is supposed to have minimal magnetism, and I expect that on its own I might be OK. However, has anyone actually checked the magnetism of 304 AFTER it has been worked. It seems from tech data that the magnetism can increase. If so that would make the whole exercise pointless.

So does the magnetism increase noticeably or not?

I do not really want to buy heavy brass sections as this is only a spare compass & really a project for the layoff. Anyway, I do not know how to form a ring in thin brass as a "Z" section for stiffness or how to form the heavier "T" section so both pieces would have to be flat strip on edge but bigger than SS & prohibitively expensive

Thanks

Thread: Chinese DRO opinions
15/01/2020 16:18:33

I already have a EMS 200 XY DRO on my mill. I would like one on my lathe but do not feel justified in spending too much as It is not my main hobby & I probably only use the lathe a couple of hours a month.

So as i am going to Ally Pallyexhibition on Friday 19 Jan I thought a cheaper option might be to go to the supplier of my DRO & buy 2 readers & then - as suggested in another post on this forum- buy a couple of switch boxes & use the same display

I am not worried about needing a set up on the mill whilst using the lathe

However, for less money & hassle I see that there are cheap complete systems on the market & I wondered what forumites experience of these are. Have they generally found them to be a waste of time & is it money down the drain

For instance I have found this **LINK**

Circa £168

I know I may have to pay VAT, but it is a lot cheaper than the one I have at present. Experiences please

Thanks

Proposed new ISO Standards for 2020 are now out for consultation:

ISO 100-5E47 - Protocols for the placement of toilet seats and their covers.

I generally place these above the toilet. I did try putting one 5 feet to the left of the toilet but this led to a pretty awful smell and it had to be moved to the correct position.

Regards.

Hi David, they need to be a precision fit, i.e. they need to go onto the top of the bowl rim with the hinged part at the back. The accuracy of the x & y about the central position can be plus or minus a tad each way. Fitting it in this way, I find them to be extremely efficient and avoids much of the smell and stops you getting a bogy surface below when in use. It does help though, for the rim to be in a reasonable horizontal plain. wink 2 Hope this helps.

Regards Nick.

In the days of wooden seats my grandfather (a carpenter) would have said that it all depended on the size of his bowler hat

I run Win 10 and have no problems. However, I also have the free "Oracle Virtual Box" loaded with all the old XP programs , data etc transferred from an older computer. I prefer some of my older software - Lotus, autocad sketch, etc because I am comfortable with it & cannot be bothered to upgrade.It also means that I can still access old data easily

Thread: Warco WM 16 VS woes
14/11/2019 16:56:54

Today I ordered the new gear at the cost of an arm, a leg & a bowl of blood.

Because my mill is bolted to some steel to raise the standard cupboard 9 inches higher, I cannot easily move it to get round the back. Therefore, I have removed the head & put it on a bench.

Looking at the gear it seems to me that it should be possibly to make a new pair of wheels in brass & silver solder them together as a pair. Alternatively make a set in plastic from some tufnol whale or Oilon (I actually have that). Fairly cheap in plastic, so can make some mistakes first, without too much expense.

Has anyone tried that? What gear cutter do I need? I have a friend with several milling machines to make them on & he has all the other bits I would need. Never tried it before but seems to me to be worth a go.

14/11/2019 07:47:31

Thanks for the help everyone. The information about the match to the Grizzly was useful as that took me to the videos. The higher gear does work still, but, presumably, that is putting greater load on the motor, which is showing signs of early departure from this world. Cannot tell why though, as it has done very little work.

I think that the gear failed because it seems that it was not engaging fully when in the locked position

Now I know how to strip the machine I will take a look inside. There is obviously something very wrong with this mill as I have not been able to do much milling with it. It vibrates so badly that just drilling holes is difficult, as it flexes like a lump of jelly.

Not one of my better purchases

Thanks again

Unfortunately I have a Warco WM 16 VS item No. 3217 year of manufacture 2015.

I appear to have stripped a gear on the low speed option, although I cannot see it very well. Probably the famous plastic one that I have heard about.

I have removed the motor cover & the front cover, but cannot work out how one gets to the gears to remove them & replace. Assuming they can be replaced. (Otherwise it will be the skip & a proper mill!!)

Can anyone who has solved this, give me some guidance on how one should approach the problem (not the skip solution, although I am sorely temptedangry 2)

Many thanks in advance

Hello Clive

Like the NHS, many do not value what is free.

The NHS is not free. I worked years paying for it, within my taxes.crying

That does not mean that I use it as though I am entitled to it though.

In fact the less I have to use it the better.

Thread: Warco WM18 milling head shake ( technically spindle is precessing) when plunge milling a blind slot.
08/10/2019 18:14:14

My WM16 shakes all over the place even when drilling a simple hole. It vibrates so much that I have elastic bands on the control box to try & stop it shaking itself to bits. The head flexes from side to side visibly.

The unit can be clamped as tight as possible & it just flexes.The whole column seems to bend. Not much use as a mill, unless machining plastics etc.

Mostly I use it as a pillar drill.

Very disappointed with it.

Thread: Stuck oil filter
12/09/2019 14:19:07

Get some strong cord about 4-5 mm diameter. Double it over in half so one end has a loop. Wind the cord round the filter so each wind covers tightly over the last. When at the end of the cord put a stick through the loop & position the stick so it also sits on end of the cord windings to jam the cord. .The action of the stick in the loop tightens the cord round the filter

Slide the cord & stick to a convenient position.You may have to re wind starting at a different point once you know where the loop finishes up.

Jiggle it all tight then lever the stick to undo the filter.

You can do it with the cord singly & a loop tied in the end & keep winding the turns over themselves.Pull the end of the cord to get the loop in the right place then tighten up & turn with the stick.

I also have a length of webbing that fits in a half inch extension bar. I wind that round & then turn the extension bar with a ratchet handle so it tightens the webbing then turns the filter

Back to the IMP- BMW made an equivalent to the Imp about the same time. I seem to recall that it had an odd crankshaft which may have had roller bearing big ends

Re. the Imp, wasn't one of the major problems the pneumatic throttle operation? Never had one but heard tales of the throttle tube coming adrift. Seem to remember they were much favoured for racing.

Yes ! used to watch them at Brands Hatch coming out of Druids , down the hill & round the South Bank with the inside wheel off the ground racing the minis. Finally lost out to the Anglias.

I think the conversion to an electric motor is easy, the hard bit is getting the batteries.

The energy density of batteries is very low compared to fuel and to have a decent run time you need huge batteries. Which if are lead acid are also very heavy.

Your 12HP engine would need to be replaced with a motor would draw 11KW assuming 80% efficiency of the controllers etc. At 48V that would be 229A, so for 1hr at full power you would need about 500AH of battery (lead acid max discharge 50%).

If you want to be green, buy biofuel.

Look at golf cart batteries. Designed for a bit more than 50% drop . Come as 6V I believe but H duty
