Thread: I wish mine was like that!

This guys a trader looking at the feedback, his maths should be better, I make 6+ riser 4=10 not 11.

I've seen Centec 2's listed as 2A's and 2B's listed as 2A's over the years, I blame cutting and pasting + it'll do or Juggard.

There are no bronze bushes in the Centec smiley

I can't remember about the main column gear box , but the MK3 vertical head certainly has bronze parts and the VH requires the same type of thick oil as the column gear box , so it would make sense to have one oil to use on both !

This Centec is horizontal only and I don't have a Mk3

Thread: Buying metal - caveat emptor.

Lets face it companies pay for C of C's because their quality controls system demands it. that's leaves suppliers with dodgy metal nowhere to sell the known / suspect stuff to except model engineers who won't set the lawyers on you when they find out it's rubbish.

Have you changed the gearbox oil?

I wouldn't subject rotary table gears to that sort of treatment especially with the extra leverage that the height of a three jaw chuck gives. If the table has 4 tee slots bolt the flywheel direct to it using the 1/2 BSF holes, if it's a 3 slot table that leaves you your faceplate idea as the best bet.

Are the bars stock?

If so try a CB175 cable, alleged to be 53"

Usual issue with cheap welders - a high-ish minimum current so it might be a hole blower on thin or rusty stuff.

Gasless wire is nearly as messy as stick welding.

Just to add, I believe the 1mm to 2mm capability, the reference to 4mm and 6mm is nonsense.

The duty cycle of 60% and 10% for low to high says 6 minutes welding 2mm needs a 54 minute cool down for summer use.

That seller is in China and he has dreadful feedback.

Unless the Chinese have renamed a town Dunstable, the items are shown as shipping from the UK - the quoted delivery date would suggest that is the case.

Nigel B

What you have to remember is all the above may be true, but that does not mean that there really is stock in the UK.

I bought a cheap as chips CCMT carbide set alleged in stock from Leicester with 5 days delivery it finally came nearly 3 weeks late duly shipped by Post Office 48hr from the UK. By all means buy direct but don't miss the Ebay deadline for reporting missing items and don't forget your guarantee might not exist as Chinese law applies.

Back up your files on a stick/external drive and keep them separate to the PC then if you get hit by ransom ware all you need to do is reload everything.

A bit of trivia:

" Bruce is a good Aussie name and well suited to a Wallaby", Back in the 1960's, Bruce was the name of a wombat in a childrens story book.

Young Aussie males travelling in the UK were all calleld "Bruce" (around the time of the baudy movie character, Barry McKenzie) because of their reputation with the ladies. Wombats are fat, lazy animals that eats roots and leaves.

Barry Humphries has a lot to answer for smiley

Slightly off the original topic, but are their welding helmets any good?

I bought one a year ago and am very pleased with it.

I think this is the same one I bought from ebay badged up as Van Haus. Went duff recently as the batteries eventually die. The way through that is to open it up & resolder 2 new button batteries in. The solar bit is only for the switching. They seem to work well though. I use mine for TIG welding

Steve.

If the darkness is adjustable and it has a grinding setting then that is also the 'off'' position for the battery.

SIP do a £40 one with these features + a normal replaceable button cell

Thread: Welder Inrush Current

Bill,

It's possible your 16A D type is a bit quick off the mark if it's a budget brand. Get a Schneider

A 20A type D will give you the discrimination you need with the house, I wouldn't drop to a C you still need the high inrush protection the C can't supply. Don't forget a D is just slower to operate so the inrush is in effect ignored the figures you are worried about are instantaneous values

Thread: Electric motor ratings
08/01/2020 21:07:35

I thought the 750w related to the HP output so 0.75KW or 1hp of work, nothing to do with electrical power.

1 HP = 550lbs x 1 ft / 1 s, which after conversion to SI unit gives you 745,6998 Watts.

There actually is a British Standard (yes British, nothing to do with EU or ISO) for making a cup of tea

And got taught at school where you had to write an essay on it , but then it was the 60's

Thread: Stuck Chuck

I would still like to know why a headless screw can jam in the parallel (through?) thread of the chuck.

Ian P

Indeed, Loctite? Or a tapering thread which would make the direction of insertion rather important.

As the OP has done this before without issue it can only be some swarf has got in the threads during tightening and locked them up.

I would try high strength Loctite in a nut assuming it went in from the rear of the chuck then blowlamp the nut off after it comes out.

If you're a gambling man it doesn't hurt to try them, just check the photos for edge quality. I've seen some that look distinctly lumpy
