Qualcast electric hedge trimmer clutch

[Harry Bloomfield]

I asked some while ago if these things might include a clutch to
prevent overload, because the drive was frequently slipping and
received no answer. It is the 600w model, with a blade able to be
rotated from H to V cut.

I have been inside and no, there is no clutch at all. The slippage was
due to a worn drive system.. The end of the motor shaft has a pinion,
which drives crown wheel, which was partially supported on one side by
a casting. The quite soft metal crown wheel had worn in one spot, which
was where it was causing slipping. The crown wheel was on a spindle,
with a small roller bearing top and bottom, bottom in rigid casting,
top bearing supported by the plastic housing. Absolutely no adjustment
anywhere at all and a very poor design.

I fitted a small washer under the bottom bearing, to push the crown
wheel a tad further out of the casting, making the crown wheel a
tighter fit against the motor pinion. It will not likely last long.

I have had it around three years, during which time have have probably
cut our bit of hedge around nine times in total, so rather disappointed
that it survived such a short time.

Ihave found that sort of behaviors in many later electric triummers.
They are built to a price and a quality that just takes them through
warranty.

A cast mezak crown wheel is pence. To machine a decent one out of hard
steel is pounds.

Go figure.

I inherited a B & D electric drill from my father - he got it around
1960. It lasted until 1995

I have had three sinec then, all scrapped.

and/or military consequences of the lie. It thus becomes vitally
important for the State to use all of its powers to repress dissent, for
the truth is the mortal enemy of the lie, and thus by extension, the
truth is the greatest enemy of the State.

Me too, it was still in GWO when I took it to the dump.

Hmm, Funny that somebody told me that the same company, probably badge
engineers a petrol Strimmer but that has drive and feed problems where it
gets stuck with no drive due to plastic engineering. Maybe they need a
better buyer or designer over there. Do Qualcast still really exist, or are
they just a badge used by somebody for el cheapo imported crap?

I still have my old 1970s b/d mains drill as good as the day it was made.
Over engineered but then if everyone made things this way they would never
get another sale would they? grin.

They are just badge engineered, cheap imports.

Such a shame as they used to make great lawn mowers at one time.

That is what the purchasers of the brand name rely upon..

Unless they made a range of products, or thought people would give
recommendations ...

Unlikely that many would buy too many and the same
consideration would apply with those, and their kids
would get the long lived product when they die too.

It has always been one real problem that prevents the best
designs from being what is sold, particularly when the stuff
that lasts forever will be more expensive to make.

The other weird thing is that cars now last much longer,
but you don’t see too many keep them much longer.

I wonder why that is?

They are relatively much cheaper to buy, people have more more and less
inclination to get involved, less of the needed skills for repairing
them themselves. Labour costs and parts to repair them are relatively
so much more expensive. Then the MOT filters many out now.

I don’t believe that any of those are the reason
most people get a brand new car now.

Well, go on, explain what you think the reasons are..

Basically they can afford to do it now with cars relatively so cheap now.

Rod Speed brought next idea :

Er, was that not well covered when I wrote - 'They are relatively much
