The table unbolts from the carriage, the vertical head comes off and you can remove the large motor. I don't think you can break it down any smaller.

There two meanings to the term wrought iron. One refers to the material and one refers to the method of construction.

Posted by Mark C on 29/09/2015 18:18:39:

Michael, interesting to see that wrought is available (albeit from a single source). I have often wondered if I could go buy a gate at a big store and then take them to trading standards for contravening goods description? I was told that they last produced wrought iron in the late 60's but that could just be anecdotal, it is obviously still available to date.

I had it pointed out to me by a site engineer when we looked at a fire escape in need of repairs (it was on an old mill). I assumed we could just weld some patches in which caused him much amusement!

Mark

PS. For interest, if you see iron work that is riveted together (like a fire escape for example) on something old it is probably wrought!

Thread: EN1A or EN8 which is best for hot bending?
24/05/2020 18:26:23

Either will be suitable. I would thread them first. And like Thor said just leave them to cool slowly so as not to induce any hardness.

Thread: Mild steel wheel blanks
24/05/2020 10:31:46

Depending on whether it was made from new mild steel or it was recycled mild steel will affect it's composition. Recycled mild steel can contain all sorts of unwanted crap including boron.

The only mild steel that I know that is made from raw iron ore is structural steel as this has to have a certificate of conformity. Where as run of the mill mild steel doesn't.

We haven't got any down on the south coast anymore!

Thread: Hammer Forging Firearms Barrels
28/04/2020 09:30:52

By forging the barrels, the steel becomes much stronger and denser. Also by forging there is no chance of any drill wander.

Thread: Painting cast iron - What have I done wrong?

New Hammerite is crap as the EU banned the use of chlorinated hydrocarbons which was the solvent used in the original mix.

If it's too cheap, there is normally reason!

Thread: Gearwheel key
16/04/2020 11:03:21

The key should only be used for location. The drive should be taken by the clamping forces of the bolt.

Thread: Correct boring with a steady - advice please :-)
13/04/2020 12:34:25

On large hydraulic cylinders you will often see steady tracks machined on the outside.

13/04/2020 11:35:39

Depends how you set the steady up as this can cause a taper. I normally set the job up using the tailstock to centre the job then set the steady up. Try running a clock gauge down the outside to make sure it is running parallel.

Thread: Essential and non-essential workers lockdown rules
10/04/2020 10:40:28

There is NO restrictions on who can work and the Police are ignorant of the guidelines if they think only essential workers are allowed to work.

The guidelines clearly state:- work from home if possible. If this is not possible you may travel to work but must observe the two metre rule.

I am still working as I am a lone worker, I have my own workshops and no one else is near me.

If the Police try to stop me from working I will be seeing them in court seeking compensation as I am not entitled to any help from the government!

I work in the vintage car world and we deal a lot in cash especially with French and German customers!

Thread: New storage space

In my workshop I used council slabs on top of slammed mot. They have moved in 10 years of driving cars on them.

Thread: Wow, what a battery
04/04/2020 10:41:46

27 PP3 batteries will give you 243 volts dc!

Posted by Nigel Graham 2 on 04/04/2020 00:07:20:

I once worked for a small electronics company that made a lot of equipment for Government labs, the Royal Navy etc. One year it gained a couple of contracts for making some special test-equipment for the old Central Electricity Generating Board's R&D lab, and our designer visited the customer to discuss what was needed.

he returned very impressed with two things he saw on a tour he was given. One was a flash-over test on a 132kV transmission-tower ("pylon" insulator. The other was a battery made to give a high direct voltage at very low current and even less noise to drive for some particular experiment. It consisted of a great stack of PP9 cells all linked in series!

Does anyone have plans or drawings for making a riser block for the vertical head?
