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

[Turbo]

Took a while to get around to it, had some free time today.

Looks pretty simple in principle to me. Water intake on bottom, four pistons of some kind that build pressure, the high pressure output is on the top. It doesn't seem to be going from one piston to another for sequentially higher pressures, but to all four at once and then to a combined high pressure side.

Brass construction, can't see no cracks.

Things I don't get about this construction:

-The two adjustable knobs, they are not connected to anything, it's just two old hoses that go around the frame and end up a the back connected to nothing. Behind the control panel in between the two knobs there is a T-fitting that goes downwards to a hose, which is connected to nothing. I think maybe it's some kind of system for taking detergent and mixing it into the output. But it's probably missing some parts. I also don't understand why that needs two valves like that.

-The oil knob, what the heck does it do? I know the housing is likely oiled for obvious reasons, but I dunno what this thing is for.

That is an unusual washer indeed! With 18l/m at 120 bar output it will have quite a kick, I'm guessing that it is 3 phase? Norcar are still in business, e-mail them a few of these photos & they will likely send you some info about it including a pts list, if you ask nicely.

Looks like you have 2 pairs of horizontally opposed pistons, possibly cam driven off a common crank though could be conrod driven too. Kew had a similar setup on one of their early pumps though theirs was horizontally opposed like a beetle engine.

The oil 'knob' could be a dipstick into the crankcase.

Of the 2 adjusters, one is likely for adding detergent, either by a venturi system on the output or into the inlet. The other adjuster might be a pressure control, maybe bleeding some of the hp output back into the inlet side.

Its entirely possible that Norcar don't make the washer at all, just re-badge it. They seem to build construction machinery, not washers!

Maybe @carbon has seen one those pumps before?

I have ordered a fistful of 1gb USB sticks, I will try and download the info onto them or get @sako243 to do it. I will get a stick to @25.4_mechanic so he can launch it into space and send the rest to @James1979 ,@roofman . @drjim and yourself. Whoever else wants the info in the future can drain it out of Carsten's cloud..

That's fantastic Bob, again pm me with your details so that I can cover your costs & postage.

I got a new charger for my 18650 cells today, Amazon got I here in less than 24 hours on a free Prime deal!
I managed to break to old 2 cell one and couldn't sensibly fix it so got this.

I bought an opus BT-C3100, a similar charger to yours & it has been a godsend to process & sort some old 18650's plus nimh cells.

I made up a false battery from wooden dowel, added a pair of jumper cables so I can use it to test & recharge individual battery cells without having to strip the battery apart. Useful for diagnosing a faulty battery which can be often down to 1 weak cell.

 

[carbon]

The fitting circled won’t be an original as it looks like a low pressure galvanised one. This could have originally been a low pressure detergent injector with the rate controlled by the two controls on the panel. If the pipes connected to these are loose in the rear it may be that they have fitted two controls to allow quickly changing from one detergent to another without swapping barrels or changing pipes. Turn one off and turn the other one on when different detergent is required. The oil fitting on the front may be a vent if the fill plug isn’t vented

 

[DennisCA]

Turbo, yes it's a 3-phase machine. It supposedly leaks near the pistons, I am hoping it's just a gasket or o-ring that can be replaced. Haven't yet opened it up.

I read up on how injectors for pressure washers worked and it's based on the venturi effect, but robs some power. At any rate I don't think I will be bothering to put it back. Seems easier to get a foam spraying gun attachment. It makes sense if that part isn't factory I guess, since the inlet and outlet should be hooked up to the two holes in the frame, guess with the modification that was no longer possible.

I assume pressure washer hoses and "guns" are built around some standards.

 

[Brad93]

How funny you should ask that ...



Yep,

and here's why:

I actually found a small surface grinder a while back, just like I was looking for.


Here at a use last night with my big son to flatten two thrust bearing races by 0.375mm each.

(The flash rust, which had overtaken you before us with the sudden rise in temperature, has also fully caught our cold workshop, here only the most necessary cleaned).

View attachment 378165


The sheet metal strip is only there to reinforce the magnetic holding force,
the races with their small bearing surface could otherwise be displaced during grinding.

Here is the purpose of the exercise:
Since I had already purchased a new top slide casting for the ML7 a long time ago and had the height reduced by 2.5mm in order to be able to use the turning steels and insert holders at least up to 12mm / 1/2" without milling off the shank, the hand lever of the Multifix basic holder was protruding into the working area, I had to change that.


View attachment 378166


The lever was exactly on the opposite side, the central retaining bolt has M10x1.5, so 0.75mm had to go down, makes 0.375mm per race - I would not have known how without a surface grinder to manage - even SWMBO had to concede (if anyone still needs arguments ... ).


I notice that I have hardly made any pictures of the machine, here are the offer pictures:

The home transport of the machine also took place in low light:

Now, of course, comes the usual: Get practice, increase precision, build suction, ....

I can say that I am pretty happy

similar to Stefan Gotteswinters BEMA grinder it seems

 

[carbon]

I assume pressure washer hoses and "guns" are built around some standards.

A single wire hose should be rated to at least 210bar for use with this. Don’t use anything smaller than 5/16” dn8 hose. Make sure any trigger/handgun is rated above 230bar as well

This is the closest I got till now, Brad, thank you,

because I still don't know who made it - mine seems to be the granddad of that BEMA and they are about 20min from here and mine was significantly cheaper ...

There I should find out more ...

Fantastic book, great illustrations

Think it's thanks to @Tinbasherdan for the recommendation.

My son bought me that last Christmas, very interesting read, but I had to skip some of the more technical bits

 

[Tinbasherdan]

To be fair I’ve worked on a fair amount of the engines in that book and I can only manage a chapter at a time before my head melts!

about £25-30k those bema grinders here. very expensive. maybe cheaper in europe?

about £25-30k those bema grinders here. very expensive. maybe cheaper in europe?

I just saw Stefan Gotteswinter's machine presentation and I'm still electrified:

I was alone very happy to have a
a) small,
b) affordable machine
c) very close to me and
d) from someone I know
e) found and even
f) got it.

And now I learn only through Brad's hint, what a hot piece this is .... the seller had definately no idea and he is a pro.

About the price:

Stefan tells in the video that the base price of the machine is just under € 30,000.00 plus tax.

In a German forum he also presents the machine, does not mention a price (envy is a devil!) but mentions that he ordered the following basic and optional equipment:

- The surface grinder
- Underframe (The machine can also be used as a table machine)
- Heidenhain ND7013 digital display with glass scales
- 5 wheel flanges for 20mm hole
- SAV magnet 200x100

... and he says: "all quite expensive extras, but fortunately only a few" - all in all he will probably have put down about 50k€ with tax ...


I still can not believe that I have such a close ancestor of it.

Granted: I still have a V-guide next to a flat guide for the table movement, not these fabulous linear ball guides (No talk of moving the table with one finger like Stefan, I stand in front of the machine, both hands on the table handwheel and have to move slightly around the bellows to feed or, like the day before yesterday, do the job together with one of my sons - it's fun and fast), no swiveling head, no thought of digitization and at least one working life the machine has already covered .... but it is at home with me.

A bunch of bits of propshaft

 

[dobbslc]

Looks a bit dry in there.

Non greasable and normally inaccessible

Still it managed 145k with no maintenance. Last 20k in my ownership towing a lot.

Went to Lidl, planned to grab a second dehumidifier but they were all gone.

Acquired this instead. I have a lot of items that need repair or modifying and I cant be arsed doing it with a needle and thread, so it seems I need to learn this.. cant be that difficult!?!

That sums up Lidl in one post.

Go in for a dehumidifier, walk out with a sewing machine

My other half can’t use one, she always gets me to sew anything that needs doing on MY sewing machine as well as needle and thread. Learnt to sew and knit before senior school as my mum made me do my own repairs. The knitting has fallen by the wayside though
