I have never seen a drill bit used in that way. Every time I think I might be pretty handy in the shop, I watch POC video and bring myself back to reality. Please don't ever stop making these videos, they are highly enjoyable.
That's ruddy brilliant! I watched a fellow who makes giant swords use his drill press in a similar manner, but he used an angle grinder on the job in the press to polish it. I think I'll have to buy a hand reamer now, could do with one of those.
Nicely done! I've used a similar technique, at larger scale, in woodworking. Router bits are made with both top and bottom-mounted pilot bearings for following patterns. I've not seen any small enough to do work like that though! I'll have to remember that drill bit trick! Another trick you can do with pattern following router bits is to combine them with a rabbet bit (I believe over there you use the term "rebate") to make larger holes than you have bits or hole saws for. I once needed a 2.5" hole in 3/4" MDF for a shop vac hose, but my biggest hole saw was only 1.5". I used the hole saw to get started, then used the rabbet bit in the router to cut a relief part way through and 1/4 wide. Then the pattern bit to follow the relief around and trim off the "shelf" of the rabbet. That made my hole 2". Repeat and you get a 2.5" hole. Keep repeating until the hole is the size you need. Use other rabbet sizes for other increments. I hope I've explained that clearly enough....it's very simple once you see it done, but perhaps not as easy to visualize from text. Thanks for the ideas! -- Mike
I always thought that the red ones were faster! I found a flexible cutting board plastic thing of the right thickness Bends but wont break and keep a spare in the on board tool box. Loved your drill press idea. Now you can go ahead and mass produce them for everyone.
I used a dremel tool, & instead of plastic I used nylon from a old cutting board. That stuff wont ever break.. So it was very fitting to become a part of a Seagull outboard.
great video mate, got loads of seagulls myself plus lots of part motors where animals have buggered them, oldest one I have still in use is a pre war 102!!
Necessity is the mother of all creation (or something like that) or put another way, designed in the pub and built in the shed. great workmanship and design ;-)
If you were to drill both holes in a simple drilling jig, add a locating pin in the block for the small hole then put your steel template in place of the washer under the plastic then use a router bit with guide bearing you could cut several at once, more efficiently too. I used to do this all the time when pattern making in all sorts of materials, you just need to get your brain thinking in a different direction. Do bear in mind drill press bearings aren't designed for side thrust and the Morse taper can let go! So maybe a router table would be a better bet?
Good grief, poc. You used a drill bit as an end mill! In a drill press! I admit I have used broken drill bits as end mills, grind them flat. But the combination of the steel template, the drill bit endmill, and the block... yes, for many many things you don't need CNC. Bravissimo!
Muy buena idea para hacer, la tarjeta del aire del carburador AMAL. Yo tengo en Málaga España un British Seagull de 5 HP Silver Century ESC 1421-JJ9 Regards
Your dedication to the preservation of this small engine is inspiring... cheers POC!

thank you :-)
Excellent video as usual. I could have thought of a dozen ways to do that and none as good as the way you did it. Thanks for the video.
Nicely done! I'd have never thought of that.

Great video
Very watchable and I don't even own a seagull!
Fantastic way to replicate.
Nicely done

red ones ?
@@poroldchap Yes, the red plastic ones [lol]
nice work skipper

thank you you have showed me a lot of how to work my 40 plus
good job mate.
well done that man, magic
great video mate, got loads of seagulls myself plus lots of part motors where animals have buggered them, oldest one I have still in use is a pre war 102!!
Guess you know there is a good site "save old seagulls" SOS

Very clever!
nice one saliler
Slick set up for a minor job.
Brilliant.
most excellent fabrication
Excellent engineering.

you are genius :)
How about HDPE cutting boards from the dollar store?
outstanding
