There are different versions, 1 hole, 2 holes a slit. It was difficult enough to drill a single #80 hole. I am sure glad the drills came in packs of 12!
Yes, using small tooling on large machinery can be challenging. I once had to mill a .010" square hole in a piece of brass with a .003" diameter end mill. I did it on a CNC mill using a microscope so I could see what the heck was going on. You could actually see the individual steps (.0001") in the movement of the table along the cutter path.

That would have been very interesting to watch Tom.
It was interesting, but there is something conceptually wrong with using a 4HP spindle running flat out to drive a .003" diameter end mill.
Tom
I agree - totally underpowered
And of course you'd have to square those corners up with a file too.
Best Regards
Rick

As it turns out, it was for an optical aperture and fortunately the corners were square enough.
I see that there are now end mills available down to .001" diameter which is downright scary.
Tom
I hope they come in packs of ten,

On the weekend I managed to get the burner assembly and the motor mounted into an old roll cage.
Yesterday, I decided to run it up and it was all going well until the hose came off of the pump outlet

Paper on the floor and a couple of drip trays now
Yuk, there's nothing worse than cleaning up used motor oil. You should make one of those wire clamp tools.

I'm going to use proper hose clamps (jubilee clip), not the spring loaded ones I thought would hold it. At the time, I didn't have any hose clamps in the correct size. It was lucky that it went when it did and not on the previous occasions I had it running with my head in close looking for leaks!
Also, ignore the fact the the flame tube is off kilter, as I have changed the design and haven't realigned it yet.
I'm hoping to fire it up on the weekend.
