What did you do today?

Yup.  You need  1/16 or 1/8 per side on the larger bits to prevent snagging the bit.

 

So 1/8th pilot, then 3/8ths, then 5/8ths?

It would be worth a try.  What kind of drill are you using?  Trick is to keep all of the drills purpundicular to the surface.

 

If you are drilling steel, oil while drilling helps reduce chatter.  I had Marvel  Mystery  Oil  handy, so that is what I used with the 3/4" holes saw today.

I did bend a pilot drill in the hole saw.  The pilot drill broke through the material suddenly, then one side of the hole saw caught, pushing everything sideways.

I drill a 1/4" hole first then go to the hole saw now. I bent/broke a few pilot bits before I figured that out.

I didn’t have my hole saws with me or I would for sure have gone with one of those instead.

I did have, and always use, cutting fluid or oil for lubrication, cooling, and to contain the metal cuttings. Keeping the heat down, iMHO, helps extend the life of the drill bits. (Always the tradeoff between drill speed and feed pressure, of course!)

the movie "Bridge over the River Kwai"

I first saw that movie as a pre-teen. It was the beginning of my realization that not all choices of actions in life would be simple. 

A phrase my Dad often used was “Any child can distinguish black and white. Adults have to discern among shades of gray."

When I use a hole saw, I drill a 1/4” hole first and have a piece of 1/4” plain rod in the hole saw arbour in place of the drill bit. I’ve found that using the hole saw with the drill bit in the arbour, the flutes of the drill bit can cause the saw to chatter and wander until the cut has started. Using a plain rod instead of the bit prevents this from occurring

I have never seen a set of blades like that!  I saw and learned something new today.

Thanks, Ranger, this is a trick I’ll try to remember!

This is the first time i ever saw or came across this bar with two holes that is used on the lift hitch.   No drawing in the RJ manuals or part number!

Certainly not an RJ expert, but I’m looking at how it’s not snug in the slot hitch and thinking “nice bit of fabrication by a PO"

You can, at a pinch, reverse the drill bit in the arbour after drilling the hole, if you don’t have any 1/4” rod? 
Iv’e found that this “trick” goes a long way in preventing oversized and out of round holes, especially in thin steel sheet.

That tow bar is probably original too. They did fit in there pretty loose and the original pin was an eye bolt like that. Most of the time that eye bolt has been long gone and replaced by a standard bolt. Even the eye bolt looks old. Of coarse a piece of bar and an eye bolt can always be replaced pretty easily.

Probably find it in a drawing for a trailer or towed attachment
