Just get a 125mm discs angle grinder, which cuts everything

I use blue spot 1mm stainless discs

Aldi may still have a few left in their stores, their online stock sold out fast

Not so good on Ally

Second what Frances said, also bloody noisy, so earmuffs a faceshield, hat and scarf necessary in a confined space.

Got one here you can have for nothing if you can pick it up or arrange collection

Just one point-- They are not normally circular holes but hexagonal. That gives flat surfaces for the weld at the new meeting point.

.

I suppose that would depend upon one’s definitions of ‘they’ and ‘normally’

The example you refer to with circular holes is not what I was referring to. If one wants to put a cut along the web of a beam then separate the 2 halves & offset & then re weld to form a deeper castellated beam one needs an edge to weld to. If the line was a wavey one the meeting points would not meet in a way which could be suitably welded & the holes would NOT be circular. Standard castellated beams cut from a simple I beam would be cut such that the line has flat edges for the weld. The hexagonal hole thus remaining would still leave room for services & I do not recall having difficulty installing them. I did fit quite a few tonnes of the stuff in a number of new schools halls etc But I do confess, that was 40 years ago & things move on, so If I am wrong then I stand corrected

The example in the one in the link would , presumably, be cut from an I beam with considerable waste.

Less waste than you might think when you look at the cunning way they are made with modern CNC cutting gear.

I think castellated beams traditionally had hexagonal holes, because they were hand burned using an oxy acetylene torch. Straight lines are easier to burn by hand than circles. They bend like bananas when cut, we used to tack them together in a jig using metal wedges to straighten the halves back up.

No issues whatsoever in the workshop except welding with a head shield, and if you need to get really close to something in an awkward spot, like working on a car.

Not usually, suppose it depends on what vehicle it is and where the tank is located etc.

Bit of a thing of the past now welding sills on, but did loads in days gone by, never took tank out and lived to tell the tale.

Harrison did a slotted table for the L5, so could be to compliment that. Colour looks about right.

Snap on, buy secondhand, they’re good quality and always be worth good money if you sell them on.

Costco used to do a decent stainless range at reasonable money.

Look for an insulated fridge container. No need to mess about lining it then.

You can get a 40 footer with a roller door for around a grand plus vat and delivery.

Hi All,

Well, guess what - I think I have it sorted. It was something a couple of you said about swapping the phases over. Not being confident with 3 phase wiring I was a bit loath to start playing around with it. But I thought I would give it a go and - hey presto! it worked. And as a bonus, the motor is running in the right direction and I haven't killed myself.

Thanks to all who have offered advice. I really appreciate it.

Cheers, Tony

Haha, post ran to three pages and the solution was nailed in the first reply, don’t you love internet forums laugh

Thread: Concrete Garages, Shelving and Catastrophe
16/06/2020 23:10:00

I use my mothers prefab concrete garage as an extra store.

Made some racking from hollow section

legs sit on floor, tops are bolted to roof joists

Reckon there must be going on for 1/2 tonne of steel sat on them with no issues.

Could easily be adapted for sheves, just by adding wood

Hi Tony

Guessing the primary coil on the motor contactor is 240v ? if so, make sure it is hooked up to the genuine 240v output leg of the converter rather than a false leg.

Also might be beneficial to start the lathe up first, leave it running and then try to start the mill.

Regards

Alan

Nothing on my lathe that i can’t physically manage at the present time. But that would be a useful addition to the mill.

last time i used the dividing head it was touch and go if i could lift the bugger on to the table, took 3 attempts and nearly did myself a mischief.

Felt stupidly dangerous and reckon it won’t be long before i simply can’t do it.

Thread: Arc welding rods
28/05/2020 18:14:38

Depends on the rods, we used to bake Low Hydrogen rods in a rod oven for a certain period of time, can’t remember the temp, but once lost my eybrows and fringe by opening the door with my face too close. May have been 300 deg C

We used to cook pies, pasties and baked potatoes in it during cold winter shifs.

Rods would then ge transfered to heated quivers on the job.

Thread: New Steel Boiler for under 200
18/05/2020 09:11:01

Things have probably changed in the 30 years since i was a boiler maker / coded welder but MIG was not accepted for pressure work.

Most of the 4ft diameter and upwards shells and dished ends were done automatically with submerged arc, and all the bosses etc stick welded with low hydrogen rods.

Smaller vessels especially stainless would be TIG root and capped with stick.

Mig was only ever used for non pressure stuff.

Way before my time there, a very small upright vessel approx 18” diameter failed under pressure test. The fella doing the testing failed to get all the air out. The door which would have been probably 4” thick blew off and bent one of the angle iron rafters in the roof, that would have been around 30ft above. Luckily no one was around when it took off for space.

Thread: Tooling for a spline

Might be cheaper and easier to just farm the job out.

i had a pair of custom shafts made for a bike engined lotus 7 clone, good few years back and i cant recall the company name, something like GB Engineering.  Think i paid in the region of £160 each

However a quick google brought a few companies up who specialize in such work.

Maybe worth a few phone calls.

You see a lot of industrial lathes with them mounted stuck out the back, but you do need plenty of room behind the lathe.

Mounted mine where you are planning to, and it can be a pest at times, just had to remove it for a one off boring job set up as it was in the way.

Looks pretty much like mine, similar vintage i would guess.

yes table is easy to get off, unbolt ram and it lifts staight off.

did mine without help, but would be much easier with two people.
