Matthias Wandel has made a few videos on band saw blade guide design. This one discussing the orientation of the back ball bearing: kzbin.info/www/bejne/jJDFhnaKeLOIo9E This one comparing four different designs: kzbin.info/www/bejne/eoK9imOYe6mcrZo

He uses wood blocks on the sides instead of bearings. I designed and printed blade guide for my saw that used bearings, and later ended up switching to hardwood side blocks. I now agree with him they are better.

Robert: goes and gets a full imperial drill bit set Me, who often has bad ideas: why not just wiggle the 10mm around until it bores it out enough to fit?

[@AM-os4ty]

Honestly that was my first thought. 🙂

[@AlexSwavely]

or, wrap sandpaper around the slightly smaller 3/8" bit

Yeah it looked like about 1.2 imperial wallers to me

Because wiggling the drill around gives you two back to back cone shapes rather than a cylinder.

[@woodworkerroyer8497]

Well, only if he is dumber than he seems. I have had a few of those "enlightening" moments myself, and I can tell you that almost losing a piece of your body to a machine is one of the things that makes most people want to NOT do that same thing again! Also, Robert, if you see this comment, look at Fastcap's Million Dollar Hand (something like that). It lets you hold small parts like those, but keeps you hand far away from the blade.

if you need to tap threads into a softer wood, try drilling and tapping as normal but then saturate the newly cut threads with super glue. Once the glue is cured run the tap through the threads again and Robert is your fathers brother.

[@darkwood777]

There are actually several ways to do it, but usually you screw metal inserts into the wood which are pre-tapped. High speed drilling of the wood with a metal tap is not tapping wood. Yeesh.

[@AgentTasmania]

Robert is him

[@scholztec]

@@AgentTasmania *woosh* 😛

[@frankfreeman1444]

Sir: Two suggestions. 1. Buy a fairly cheap set of center-cutting end mills for your slotting and carving operations if you are going to use a drill press to accomplish them. 2. If you MUST put screw threads directly into wood, use Helicoils or similar thread repair inserts. They will last much longer and be stronger as well. By the way, 2 flute cutters, like drill bits, cut triangular holes. 4 flutes cut rectangular holes, etc. The number of flutes in the cutter, plus one, is the number of "corners" in the resulting hole. A framed with 6 or 8 flutes cuts a founder hole with smoother walls and more accurate and consistent diameter. I know you didn't ask, but I am an old fart, I envy your having that workshop and I just love to poke the bear. 🙏

[@robbin763]

keep the blade just off the bearings, its ok if they touch when your cutting but not when its jus running. great job I need this for my vintage Delta 785

[@RonLeedy]

I inherited an imperial drill set from my grandfather. Haven’t used half of them but it’s amazing when I’ve needed that one size it’s there.

[@Pauken11]

Nice job! One reason for the thrust bearing to be 90 degrees to the blade is more surface area contacting the back of the blade, rather than a single point with a parallel bearing. I’d fix the upper blade guard sooner rather than later. Keeping your hands away from the exposed part of the blade isn’t enough. If and when the blade breaks, the loose blade can nastily cut you. I’d make this my very next project.

[@raimundoferreira7626]

And that's the problem , the thrust bearing is the one that does most of the work to keep the blade in place , more contact area will only increase the friction between the blade and the bearing , therefore creating / generation more HEAT when the saw in at work , thats the last thing you want to do That heat will damage the blade and it loose it's sharp edge quicker than you expected

[@mtyquinn6]

I agree with you @jim Gott. to spread the load of the contact of the back of the blade helps prevent it from buckling and binding on the side guide rollers (or blocks).

[@ssskids123]

Very cool project! Fwiw, clamping a board across my drill press table (and later building at t-slot base with a fence) transformed my drill press for me. I now had a way to support what I was drilling and haven’t had any more cases where the item I was drilling got bound to the bit. Plus it is now very easy to clamp items to a stable surface (the fence) and keep my hands well away.

Great work! Thanks for sharing your adventure!

[@adventuresinnorfolk4756]

Love this project, definitely want to improve my bandsaw guides like this.

[@CsongorHalmai]

The answer for the question related to the orientation of the ball bearing is simple. If the spinning plane of the ball bearing would be parallel to the plane of the blade then the blade would run on the same perimeter every time and would cut a trench into the surface of the ball bearing very quickly. By contrast, if it is perpendicular then the blade continuously turns the ball bearing and it always scratches a new part of the surface of the ball bearing. Therefore it wears out more slowly. This is what I think the correct answer is. :)

[@muneer24]

When you sneezed and said unrelated....I actually laughed out loud. I am totally using this

[@leesportster]

[@Jeff1Jeff2Jeff3Jeff]

Your enthusiasm is unlimited, and infectious. Keep it going!

[@rivernet62]

In my experience, the reason for the bearing being 90 degrees in the wrong direction is so that once sawdust slows it down it will get a groove worn in it which will trap the blade and guarantee that it (the blade) *always* points in any direction but the one you want.

[@slawnski]

[@patrickkrenz515]

Before using helicoils on a cylinder head I actually practiced installing them in a 2x4 and it worked great.

[@radiohirsch]

Guess it really needs to be hard wood to have a chance of holding any force. Also UNC probably works better than metric or UNF due to the coarser thread pitch

[@akbychoice]

Purple Heart wood is extremely hard and hard on the cutting tools as well.

[@alandesgrange9703]

Hitting it with thin super glue, will also harden the threads up.

That black piece you removed is where I squeezed my dust extraction brush in its purpose was to remove the dust before it got onto the rubber Tyre on the lower wheel, secondly it also sucked the dust through the blade insert which I drill 3/16 holes in to assist with downward dust removal.

[@ProjectsandThings]

I’ve been fiddling with alignment and bearigns on my old Bandsaw as well, I think you have me given me some good ideas. Thanks dude!

[@martykorn9266]

2 reasons. 1. Using the side of the outer race is quieter than the OD in this application. 2. When pushing a narrow blade against the outside of a round bearing you end up with the absolute minimum contact patch as well as a tendency to encourage the blade to lean over.

[@MikeGusFifteen]

bearings are faced sideways on guides because facing them towards the blade leads to a terrible noise and will also rub a groove into the bearing over time

[@camillosteuss]

That is why you are supposed to have earplugs to avoid hearing unwanted noise, tho i despise the thought as hearing shit is what gives you an idea of something not working properly, and secondly, the bearing is a disposable tool in this case, just like a tire on a car, which is supposed to be changed when worn out, and with it backing the blade up, despite it making noise and being worn, it prevents the blade from snapping when you shove a chunk of something that would force the blade back and put too much tension on it...

[@akbychoice]

If the bearing is spinning and the saw is adjusted properly, very little grooving. Those standard side mounted bearings wear terribly as the blade is being rubbed sideways wearing out both blade a bearing side face.

[@Beverlys-Hillbilly]

I need to try this on my old Delta!

[@paulheitkemper1559]

it's oriented to the side because the pin in the center of it is an eccentric, allowing a bit of left-right adjustment. Also, being oriented side-to-side allows for a more compact guide assembly with fewer moment arm forces. which I fear you will come to experience in time due to those tiny wood pieces.

[@treymoore6901]

Nice build, Robert! I wanted to caution you on how you held the piece at 10:15. The direction of force of your appendages should never be towards the blade, within maybe 8 inches or so. The workpiece can always unexpectedly kick out, and reaction times are far too slow. Always factor in the slim possibility because it just takes once. I speak from experience, but thankfully my accident didn’t cut through bone and is mostly healed.

[@borjesvensson8661]

A sideways bearing or spinning disk means the entire surface is in contact with the spine of the sawblade so it does not develop a grove unless the bearing seizes up.

[@richardhenry5961]

I got to say this, that is impressive in what you did... I have a Band Saw CARTER Guide System. 3-bearing wheels top & bottom. I had blocks, yet gave me a lot of issues. It was an investment $150.00 for the new Carter Guides. The funny part is that my BAND-SAW was $189.00 Penn State Industries 1992. Did the Carter Guides in 2010. I changed the tires on the wheels, better quality for blade control and the Carter Guides made it a completely different & a better band-saw. Blades last for yrs instead months. It was worth the investment just in saving blades.
