That's quite remarkable that bike shops can afford to stock them. With only two each per emperor, harvesting imperial balls must be a very expensive operation.  :)

I'll get my coat....
Anybody got a syringe I can use to squeeze the magic smoke back into this?

I don't know if bike shops are open, but if you look on ePay, be careful not to buy the pre-rusted steel balls.  :-DD

Bearing balls always amaze me. The nature of them should make them hard to manufacture yet some clever gits managed to develop a process to make them well, cheap and in droves. Us considering them mundane is an industrial marvel.

Closing out the right OT Rovatti PTO pump rebuild.....finished !

The more I've worked on this thing the more I'm impressed with its design features.



Back when we were at this stage ^ the worry was how to get the impeller off the keyed taper without breaking it when in fact it's piss simple due to using Timken bearings on the pump shaft and having a grubscrew on one end to preload the bearings.
With one stuffed bearing there was just enough end float on the shaft to get a couple of screwdrivers behind the impeller however with new bearings there certainly is not.  :-//
Had me wondering for a bit after partial reassembly how one might get the impeller off as there are no threaded puller holes in it and then it dawned on me.
Clearances behind the impeller are miniscule therefore when the bearing preload screw is wound back to allow shaft end play the impeller can be pressed back against the housing where just undoing the nut some and using a drift on the pump shaft pops it cleanly off the taper. Shit simple and clever design. Color me impressed.  ;D

Anyways all completed now after a real last 2hr battle with getting the 2 halves of the driveshaft to slide completely together.
Some monkey had previously decided to grind a small taper on the end of the 3 side lemon tube inner driveshaft which inhibits it scraping the rust, dirt and gunge from inside of the outer however after cutting it square again so a nice sharp edge could do it thing and then some time with hammers and in the washbath it's like a new'un again.  :phew:

Completed project minus a fitting to allow connection to our pipe work.

Yeah, lots of HP rack gear have very deep cases. I'm on the verge of putting some bookshelves behind my desk to extend the surface area. TEA-world problem. :-DD

Solved by purpose made and matched to available space shelves:


Show off! :-DD

That looks great, capt. There's certainly no substitute for a custom solution.

There's a shortcoming with that solution: Some of my TEA has short cases, that would leave a lot of space behind. Somehow that feels inefficient to leave a hole behind an instrument.
With all that boat anchor stuff on those shelves  "...... but Captn,..... she canna take any more......"   😁 apologies to the Trekkies.
Whoah! Watch where that landed we might need it later.

Another heads for the UK Philips fanboys, there is this PM3365/50 scope, it is part of her late husbands collection so there are other items and electronic books / magazines etc, well worth a look.

Well, the good old Royal Mail must really be backlogged, as we've just had that unheard of thing, a Sunday delivery. Sent on the 5th, by the Royal Mail 48hr service it's only ten days overdue.

Just to annoy the Dragon - thinking back to his travails to get the same, what it was is a 1 litre bottle of fully synthetic ISO 32 sewing machine oil which came to the princely sum of £7.30 ($12.61 Canukistan Kopeks) including snail like delivery.

My local RM office do Sunday deliveries. It’s usually whatever they found left under something at the end of the week that is chucked in a van and delivered by some dude who drew the short straw that week or at least comes across as apologetic enough not to get stabbed by customers.

Yes they are backlogged in some areas. Parts of Essex have allegedly not had a post delivery since 14th December  :palm:

TEA Pump?
in a odd coincidence, some TEA arrived on Friday and was accompanied by some pump impellors  :-//

So what is the TEA? Bonus if any one knows what the pump belongs too, From the NSN linked part number (FV668861) its off a bit of  British Army kit. BTW I'd call it an impeller, but the box and NSN listing calls it an impellor.

I bought one of these:
www.ebay.co.uk/itm/HYDRAULIC-OIL-FUCHS-LUBRICANTS-MIL-SPEC-PREMIUM-QUALITY-HYDRAULIC-OIL-5L-CAN/143226367787
for the Myford over a year ago. OM33 is a high quality ISO 32 oil with no additives that corrode yellow metal bearings. 5 litres for £16.49 delivered (I know the seller, he dropped it off for a cup of coffee on his way home from Tesco  :-+ )
£3.30 a liter. Similar oil sold for Myford lathes goes for about £20 a litre  :-//

If anyone in the UK need a small qty let me know.

It's a shame most is collection only and so far away. The Phillips is a re-list, probably non pick up. Some of his kit is making good money, if she could sort out shipping it would probably get a lot more.

I've bought a few items from that seller last year including the HP 5325B counter, I'm surprised as they hadn't listed anything for a few months and now they have found more interesting stuff.
The Philips scope was sold last week, so I guess the original buyer didn't read about collection only or isn't from the UK.  :palm:
BD, some of the collection has made quite a lot, but there will always be stuff that isn't worth much.

Robert, they were shipping when they started, but I guess they got fed up with boxing it up, quite understandable given the amount of stuff they have had to sell.
