I am building a marble run with my son. For some of the connector pieces, I am borrowing (ie: hijacking) some ideas from a popular brand of mass produced marble runs.
I am trying to figure out the best bit for drilling the hole out of the blocks I made. The blocks are made of scrap hard maple. I need to use a bit at least 9/16” and no larger than 5/8”. I have a Shop Fox radial drill press, 1/2 HP. The holes will be between 1 and 2” deep.
So, auger bit? Spiral bit? A bit I have never heard of? Thoughts…? Thanks!!!

A Forstner bit is probably the best solution. I’d hold the parts at an angle, with a clamp flat on the table, rather than changing the angle of the drill.

John, I give up what is that in the photo?

Ditto on the forstner bit, with a 9/16 bit you’ll likely have a few thousandths over bore, more so if you sand the bore with rolled up paper.

I hate it when a post starts to drift, but since oldnovice asked …
It’s the layer in my XyloSpider where the cam-actuated pushrod comes through the body to make the top hat go up and down.
I thought that was obvious. :)
It’s much easier to drill two short holes rather than one long hole.

Well John I really don’t consider my question as a drift based on the context of the opening question!

I believe it was more of a perfect segue into your project!

XyloSpider is RAD! I love drift…I always have more to learn, so drift into amazing projects like XyloSpider never bugs me (pun intended) :) I want to add musical bars to the marble run at some point, too.
Forstner bit, eh? Well, that is great news since I already have that size in a forstner. I thought it would be too much work for the drill to bore that deep with a forstner, but I am happy to save myself the money in more bits and just try that out!

John the Xylospider is way cool!!!

second the forstner bit -
the auger and spade bit tend to have not real clean entry holes.
The Forstner makes a nice clean bottom to the hole.

oldnovice: Sorry, man. I wasn’t implying that you’re a troublemaker. :) Jenine: Glad to hear that you like the XyloSpider. Here’s a link to the video … https://vimeo.com/78777697 Jenine (again): Matthias Wandel is probably the master of the marble machine. Here’s one link, but there are a lot more videos and articles on his website. http://woodgears.ca/marbles/run.html

Love the video! So cool! My son would love one of those! Kid you not, he plays with ANYTHING made out of wood for so much longer compared to all of the modern toys he has. It is awesome, mom’s little boy :).

I have seen MANY of Matthias’ videos. Most kids like watching cartoons…mine LOVES watching wood videos with me, and lately, all we watch is Matthias around here :) that guy is as big a celebrity in my house as Mickey Mouse in other houses with 4 year old kids :)

John, I’m with oldnovice. Kinda sneaky. Market your gadgets and oh, by the way here’s a link to your marbles…

Jenine: Glad you liked the XyloSpider video, and I forwarded your kind words regarding Matthias on to him. You can contact him directly at mwandel@sentex.ca
I’m sure he’d love to hear from you and your son.

And for those who thought I was indulging in shameless self-promotion … some things are better left unsaid.

Didn’t seem like a plug to me – I honestly would not have understood exactly what you meant from the statement alone. I guess I am just a visual person :) Nice pattern you glued to the wood, very precise!

Jenine: Just went back and read … “I thought it would be too much work for the drill to bore that deep with a forstner”.
Don’t try to make the hole in one pass. Drill down about the height of the bit head, and then ALMOST pull it out to remove the waste. Then drill down the depth of another bit head, etc. This will help the bit do its work and keep things from overheating.

BTW, for anyone else doing anything similar with marbles (way off topic), Matthias Wendel provides lots of great instructions for building one at his site – including this wonderful step by step: http://woodgears.ca/mm2/distributor/index.html

Hey John I was not offended being called a forum drifter, at my age that comes it comes naturally!
