Well maybe it does have some form of soft start to not load the motor too
much at start which is when it will draw most current. No idea how they
might do this unless its some kind of centrifugal clutch.

Some questions.

I was happily grinding my angles when the bearings began to go. The gearbox
was hot though the motor was cool, and it felt like an engine that kept
missing. It made unwelcome bearing noises as it spun down. Also the metal
was bouncing about a bit on the disc surface, which the new machine doesn't
do. So the bearings somewhere in there are almost toast. Is it worth
unscrewing the gearbox & lubing or anything? It's a cheap Ferm I got 15
years ago for £15 or 16, I certainly can't complain.

Got a new grinder from Aldi. Was going to get a Mak but Aldi had them in
stock, Screwfix didn't so changed my mind, needed to get on with it. It runs
smoothly. It has a huge long tail, perhaps for better stability I don't
know. Holding the trigger on is a bit of a pain, the old Ferm just locked
on. It has a more effective guard - 2 in fact. But I think it's faulty as
the disc spins up much slower than the motor does. Just wanted a quick
sanity check that this isn't some weird sort of mechanical soft start
mechanism. It did the job no problem though. It has variable speed too, not
often useful but will be for paint stripping.

Aldi also have 4 diamond discs for 3.99, & 10 cutting discs + 1 grind disc
for 3.99.
