You guys are all aware that laminated brushes are used to reduce sparking because of their resistance, yes? The different grade of carbon in the middle dissipates the inductive flash between adjacent segments on the commutator, so that rather than having a short accross two segs, you’ve got a number of ohms…
Ta, but the punter did call them and he didn’t like the idea of a £75 callout for a £20 (or whatever…) element…
Well to get a controller with *outside* temp input wil be serious money- this kind of optimisation system is generally used only in industrial setups- unless that is you just mean it’s got a frost-stat?
there are plenty of time-programmable ‘stats available these days; I can heartily recommend the Digistat 3 from Drayton. Different temps for different times of day, a night-time setback, and (IIRC) in-house frost protection even if you switch the system down say, for a vacation…
It’s my experience that it’s well worth paying for better quality Torx bits, as some of the cheaper ones are more brittle. That’s the only downside of Torx; damn all chance of cam-out means it IS easier to overtorque them. Might be worth looking at the torsionzone style bits from Wera and the like.
Also well worth hitting the bit as sharp a tap as you can without damaging anything, with the intention of breaking the rust-hold.
(Apologies if you already do this, but I’m sure there are plenty out there who haven’t had experience in the motor trade…)True enough. looked like a big plastic bin sliding out of the cupboard. I recall them being around when I was doing my kitchen up so thats ? six or more years back…
Depending on how ones’ business operates, you might look at the accounting package “Cashbook Complete” from Acclaim software in NZ. It’ll do all the cash/ contact/ stock control that the average small business might require. As I’m on my own ( not needing on-line call scheduling or anything like that) I run happily with Cashbook, and schedule jobs on a freeware reminder system “Quick to-do light”
Flyman, don’t you really mean AC? Inverter drive from rectified mains?
Are the motors single phase or three phase, and does anyone know how similar the latest Zanussis with induction drive are?Egads, the Penguin speaks the truth. I take it all back, evidently my partno. crossreference is in error…
You’ll not get a manual. An interlock isn’t too dear, but if you’re tight (like me), have a go at fixing your old one. Now this procedure applies to my old 918T, but I believe it’s the same (or at least a very similar) interlock. Pull it out (after first removing the mains plug; standard warning…) and check for wear on it’s slide-plate where the latch engages with it. Release the outer ring of the doorseal then the two screws at the latch to free it.
A bit of judicious tweaking with a pair of pliers (to overcome the wear) should get you latching neatly again. You’ll see how the plate must be in exactly the right place for the little plastic interlock to pop out through the hole, and so which way to adjust the tabs that the latch slides into.
If not, well, at least you know how to fit the new one!/standard disclaimer again. It worked for me, can’t guarantee it’ll work for you, but for gawds sake pull the mains plug out before starting…
