I just got done doing this very same thing but it was a repair on a back gear they lost 2 teeth in a row. I actually did it twice I filled one with brazing rod and cut teeth then on my other spirits embley I carved out a notch and put a tiny block of cast iron in it and cut the teeth with a fly cutter. Worked amazingly well I was very surprised. Of course all I did was shape the cutter so it fit by eye. Those back gears are more forgiving they're kind of a loose sloppy fit anyway. The brass ones working like a champ so I have a backup. I found an amazing way to sections cast iron I take my brazing rod brass rod heated up and pounded into a foil a heavy foil I should say cut it out and press it into the slot with the cast iron replacement piece of course you have to clean it very well and sprinkle a little bit of flux in it I just use borax. Works good

Hi. I recently had to make a similar toothed belt drive but in my case the driven gear was a lot larger than the driving gear. Also it was a short belt with the gears close together. I realised that I didn't need to cut teeth on my driven gear so I didn't need to size it exactly either. I just made it as large as possible (plain pulley wheel). It works great and the belt doesn't slip. I reckon it's better than if I had cut the teeth and also the belt will last longer. Worth considering in some applications.

I made it from regular steel from a scrap cut out piece from a cnc gastorch. When i tested it in my lathe i heard a ringing sound exactly the same frequens as if i tap it with something. Very anoying sound. The gear have a great profile. So there is nothing wrong there thats causing the sound. The original gear are made of cast iron and have four spokes. I think the diffrence lays there. Never expected that. Do you have any idea how to fix this problem?

I don't believe you mentioned it in this video but I recall in another video you demonstrated how you center the cutter for cutting a keyway in the shaper. The process I recall seeing was simply dragging the cutter in and out of the bore until it scored a very light line and eyeballing it center. While I'm sure this is fine for 90% of jobs, there must be some jobs where this isn't good enough. For those jobs how would you do it?

Stefan, You seem to use loctite to permanently hold round things together such as sleeves and shafts. I understand that in low torque applications that this method is a quick way. But with this timing gear, you have 4 "keyways" which I would consider a setup for higher torque drives. Wouldn't a "Dutch Key" be preferred (2 opposing set screws threaded axially on split line)? I just don't have much experience and therefore confidence in the loctite adhesive method to permanently bond. I have seen where heat is used to remove the parts with loctite bonds.
@JaakkoF
7 жыл бұрын
If you use Loctite meant for glueing cylindrical parts and the parts are a sliding fit, you can pretty much assume they behave like a solid workpiece, granted that both parts were clean and you have 100 % coverage of the areas touching. I remember when someone with a bit of Loctite on their hands put a Morse taper 4 tool in the lathes tailstock and it had to be disassembled and brought to the hydraulic press, where it took roughly 40 tons to get the parts separated. In the case Stefan here had, where he had steel hub and aluminum ring, a shrink fit would have been a very easy to do due to the different metals. Rule of thumb would be 0.001 mm per mm of size difference, so with a 20 mm hub your hole would be 19.98 or even 19.95 as the ring is aluminum and expands way more than steel. Shrink fits usually are disassembled by torching in half or just turning it to chips, pretty much permanent.

If you have a tool &die grinder (as you do) then for a one-off, single-point is the way to go. If you don't, then you have to hand-file the fly cutter. This is a pain and you are certain to get the radii unsymmetrical unless you have an optical comparator :(. Or a steadier hand than mine. If you have a many-off, as in a clock, then a multipoint relieved cutter is better and the basic process is home shoppable and described in www.deansphotograpica.com/projects/multipoint/multipoint.html. I am currently doing this, but using the "button method" due to Don Unwin, described in Ivan Law's book on gear cutting. It involves nothing worse than an eccentric arbor and a set of turned buttons.
