Today I acquired...........

[TEO]

And these turned up earlier this week. Powder for the rototec and eutalloy torches.

First time I've come across either of these processes, looks fantastic. Can you shed some light please as a quick Google didn't show the difference between the two?

I think @bR39Da has a thread on them somewhere

Thanks I'll go find that, sorry Brad.

Droopsnoot, what size beam compass are you looking for? I've got one hanging around doing nothing, made in Germany, 2 feet long with an extra 1 foot extension piece so you could do circles up to 6 foot diameter.

Ah, that's a little bigger than I was looking for - mine was for doing stuff like brake disc backing shields, maybe around 9" diameter. I don't do it very often, and there's ways around it, it's just something I'd like if it was cheap. Thanks for the thought though.

More space and access in the shed, which is always good. There's a rich seam of treasure to be mined.

Replacing my Benzomatic torch with a Rothenberger SuperFire 2 as recommended on here. Only connected it to a bottle to check over but makes a change to instant lighting and having an adjustable flame. Extension Hose and Bag only added an extra £28 to purchase.

Some heavy duty castor wheels, cast wheels, greasable, 4 fixed and 4 locking swivel, unfortunately the swivel doesn't lock just the wheel, but for £20 I'm not complaining!

Also a load of carbide milling cutters, all new thechnicut, all sorts of profiles and sizes, I'll be adding the guys Facebook post to the for sale section as he's not wanting stupid money for them, these 33 cost me less than 5 quid each!

 

[TEO]

The rototec is for building up rotating components like shafts or wheels etc in a lathe. You spin the part at a given rpm/diameter. Spray the powder on at a 100° preheat. You then have a choice, some powders you leave in a cold state and some powders you can spray then fuse to the shaft making a metallurgical bond, much like brazing.

The cold powders ensure no shaft distortion or warping. Adhesion obviously isn't as strong as it relies on a micro bond between each droplet of powder and the part.
When you fuse them the powder the boron and silicon form a fluxing agent and you get a proper bond to the part.

The eutalloy process is primarily for hardfacing. But you can basically puddle weld with nickel powder. That is good for cast iron, tool steels, anything crack sensitive.

That's really impressive, thanks for the explanation

A timing light to play about with but it must be faulty as it keeps flashing when the engine is running

 

[Cuthy246]

Not today but yesterday had my graduation. I am no longer in the further education system . Now a fully qualified civil engineer

 

[Onoff]

6 croissants and 4 of these from The Middle:

A bit of a steal imo at £9.99 ea. Might buy another 6. That'd sort my small storage requirements.

If you get your blink rate at the correct frequencies, the light stays on
