maybe a ring shaped burner?

Are you permitted to make a heat retaining cowl around the hot tube? Just a bit of sheet to guide the flame so that all of the tube is heated and less heat is radiated away from the tube?

Thread: Clean hands?

I use original green Swarfega. I did discover a decade ago that I'm allergic to D-limonene, the substance used in the citrus based cleaners.

As discovered by my late father in law and verified by me:- Making a batch of pastry in the kitchen is a remarkably good way of cleaning out dirty fingernailswink.

Thread: Multi page threads.

I, like many others in the Western Hemisphere, was taught at school to read from the top of the page to the bottom. I really can't stand top posting or anything that emulates it.

Bah Humbug!

Thread: What's the best alternative to 'loctited'
24/05/2018 03:26:31

I'm quite happy with the vernacular term 'loctited'. I'm far happier with an indication of which particular adhesive was used, and why. I quite often use Permabond 1046 for poor fits. Why? because I've got a couple of large bottles of the stuff and it's thicker than Loctite 603 or 648 smiley.

I'm using ClamWin for two reasons.

1) I use it on the linux web/mail/ftp/firewall servers

2) The main two machines I use are running winders server (2008 R2 and 2012) and the likes of Avast, AVG etc. are expensive for the winders server platform.

Used to use Avast after the company stopped allowing employees to legally use the corporate Sophos license* and never had problems at the time. Clam hasn't caused problems either.

 

*I was in the IT dept. We had a policy, before we were taken over by another company, that we'd rather our users were protected against viruses than have them bring infected floppies into work or dial in with an infected machine.

Thread: Discount codes and email harvesting

So when are you going to offer a discount code that works, Ketan? cheeky

Thread: Brass bar , 55 mm - ?supplier

Replied the same way

Thread: EDGWICK 20" SHAPER
20/05/2018 16:31:23

Much more of a machine than my 10" Royal. Mine's got vertical feed to the table, but power feed when cutting dovetails etc. is a nice touch.

If it's not too late, one word of warning that I gained from my Edgwick rotary table:- that lovely translucent green paint on the name plate is soluble in aggressive thinners, it's probably cellulose. If you want to keep it, be gentle when cleaning.

Thread: Brass bar , 55 mm - ?supplier
20/05/2018 16:19:11

If it's of any help, I've got some 3" CZ121 bar you could use How about £25 for 6" and £6.50 for Myhermes shipping?

Only because I had a B25 as a student laugh.

It's a pity Rugely power station and its ME club are both history. We might have been able to wangle a tour aloing with the meet up/show and tell.

Thread: Bent leadscrew?

<snip>

When half nuts are engaged they move the leadscrew towards the lathe bed by enough for Stevie Wonder to see it.

That definitely implies that either the saddle gib is loose or there is enough wear in the bed near the headstock that it can't be adjusted sufficiently to get free movement at the tailstock without slop at the headstock end.

Please ignore this post. I was reading it as the apron moving, not the leadscrew moving. Stupid boy!

Or they missed it crying.

I think I'm in the Midlands, specify a where and when and I'll get off my backside and come.

Thread: Dead centre temper.
16/05/2018 21:55:04

Hard as you can get it for the dead centre. Either soft or about 30HRc for the live (headstock) centre, so you can turn it concentric when needed.

Mark do you have any manual etc?

I've only got some 'recent' advertising stuff that relates to the BCA MkIII. But Tony's website has some more information, plus manuals.

Thread: Weldon Shank Tool Holding

David, that sounds an interesting tool holding system, how do you remove the tool once it,s in place?

Ian S C

Unless the coefficient of expansion is much greater for the holder, it won’t loosen on heating. Cryogenic cooling might help, if appropriate. Otherwise the holder would need to be removed from the tool - in chips - I would imagine.

It does work smiley. With the induction heater, you can put 10-20kW of heat into the outer 1/8" of a 1.5" diameter toolholder. The expansion of the outer layers opens the bore before the heat can transfer to the tool shank.

Marvelous things for the production shop.

Thread: sherry shelf life.
06/05/2018 23:49:08

The 2012 LBV port I've been testing tonight seems a bit young, compared with the real stuff. But I don't think it's going to be getting a lot older (long day, injured wrist, yada yada)
