What a silly billy!
I've been using a hole saw to make holes for my bike carb manifold, and it was a struggle from the beginning...
The pillar drill was set up for exactly the right speed, but the saw kept stalling unless I put on tons of cutting fluid. The saw was brand new, so it
wasn't due to bluntness.
The first hole took nearly an hour... drilled a bit, cleared the teeth, squirted some cutting fluid, carried on...
The second and third hole took just as long, but I persevered...
On the last hole, the saw kept stalling ALL the time, so I lifted the pulley cover and over-rode the safety switch, just to see which belt was
slipping... and it wasn't a belt, it was the pulley on the drill spindle! I tightened up 1 nut... and after that the last hole took barely 10
minutes to cut!
Oh, how I laughed...

I remember at Uni in the engineering workshop, Ompracash Sharma was drilling a 3mm mild steel plate for about 15 minutes with a hand drill. Loads of
cutting fluid, then a squirt of coolant, smoke, lots of smoke! Then somebody walked up and switched the drill to clockwise and it went through in
about 10 seconds!

One of my mates was a technician in a Southend secondary school. A stroppy kid was giving him grief, then tried to cut some metal with a woodworking
tenon saw. My mate gave him a b*ll*cking, then gave him a proper hacksaw - with the blade in backwards. The kid was knackered after 30 minutes of
metal cutting!
Running the drill backwards is in the same league as my loose pulley...

Cut my manifold holes with a wood working coping saw and plenty of cutting fluid, took about 10 mins for each port including matching them to the head
after cutting (Easier to do with just the plate )

my pillar drill started doing the same..
pulley slipping on the drive shaft.. the big grub screw has made a nice big groove on the shaft, not sure how long it will still keep going..
Its only a cheapy, I think it was £50 years and years ago..the thing has done well in its time of lots of use..
the on/off push buttons have dis-intergrated, its now held 'on' permanently with a plastic G-clamp and switched by the mains..
mmmmm.... health and safety...
RobinHood 2B 2.0i pinto, Keihin 38mm Carbs, lightened flywheel, O'Mori remote filter kit, 10 row oil cooler. Modified head, 10.2cr, special
valves FR22 cam, 4- 1 header.

I wired the switch out on mine as it did not latch. I was going to put a flick switch in but never got round to it.

I went into the RSPCA office the other day. It was so small you could hardly swing a cat in there.
