planeur Posted March 1, 2020 Report Share Posted March 1, 2020 (edited) Being my first project of that kind , I have to improvise some technique, so here it is ! What do you think of my technique to cut the wheel? I begin by cutting all the round top of each tooth , then I cut all the left side of each tooth, then the right side to the bottom. I try other manners and I found that I was doing a better job like that . What is your technique to do that ? I will be posting the beginning of it very soon!

kmmcrafts Posted March 1, 2020 Report Share Posted March 1, 2020 Everyone has their different style that works for them.. To me (being I'm a production minded cutter ) seems like a lot of extra cutting and blades to go through to get to a finished piece.. I'd have just started at one point and cut it out all in one shot.. Looks like you might have quite a project started.. be interested to see the process and the finished piece.

planeur Posted March 1, 2020 Author Report Share Posted March 1, 2020 I agree with you Kevin but I am not yet sure enough of my means to make the small curves, but it's coming ! And I will try to use smaller blade , I had used the Pegas #5 (12X). And the piece is quite thick .500" ! Have a good day, I am going skiing , skating cross country planeur OCtoolguy and kmmcrafts 2 Quote Link to comment Share on other sites More sharing options...

Have a good day, I am going skiing , skating cross country planeur My wife like the cross country skiing.. I've never really tried it.. More of a bicyclist myself.. riding is quite interesting in the snow though.. when i was younger it didn't stop me much... neither did the cold.. but now.. I just ride on nicer days.. In my younger days it was almost a daily thing to get up early and ride all day.. not come home until dark.. and do nothing but ride all day long.. Dad put a odometer / speedometer on my bike because he always thought I was just hanging out at friends houses.. when he seen it was nothing for me to be doing 100 - 150 miles a day on my bike.. nobody could believe it.. Then when I got a drivers licence I still rode my bike to work (8 miles ) at the lumber mill work 8-10 hours stacking lumber coming off the mill or making pallets and then ride home.. These days.. I could do it still.. but I might not do it again for several days.. back then it was every day, LOL Enjoy you skiing. scrollingforsanity, OCtoolguy and RabidAlien 3 Quote Link to comment Share on other sites More sharing options...
Scrappile Posted March 1, 2020 Report Share Posted March 1, 2020 I cut gears similar to what you describe. Only I cut each notch both directions before moving to the next. stoney, scrollingforsanity, OCtoolguy and 1 other 3 1 Quote Link to comment Share on other sites More sharing options...
OCtoolguy Posted March 1, 2020 Report Share Posted March 1, 2020 Matthias Wandel has some interesting videos on his website woodgears.ca. He has a great program for estimating gear sizes etc but I recall watching him cut gears. Very interesting guy. He has made a ton of neat shop tools out of wood. planeur 1 Quote Link to comment Share on other sites More sharing options...
planeur Posted March 2, 2020 Author Report Share Posted March 2, 2020 Thanks a lot Ray, this man is a genius, I had seen a couple of his video and gabarit. I am already on his site! Thanks planeur OCtoolguy 1 Quote Link to comment Share on other sites More sharing options...
Rolf Posted March 2, 2020 Report Share Posted March 2, 2020 (edited) I built my first clock back in 2013 It was a Brian Law clock that SSWWC magazine asked me to make. Most important is of course the precise location of the center hole. I drew a circle about 1/8 outside the top of the teeth. I then cut the teeth gullets. I found this process eliminated the chipping of the plywood tooth ends. I made a Jig for my disk sander. Tips were all precisely centered on the center of the gear. the article was in the Summer issue of SSWWC.

planeur Posted March 3, 2020 Author Report Share Posted March 3, 2020 (edited) Thanks Rolf, they are good tips and tricks, I will make also a jig for sanding the wheel. I had saw that jig before. Good idea also for the ext. cercle. In fact you cut to the ext. cercle without much precision, then sand at the right dimension. What kind of blade are you using ? planeur Edited March 3, 2020 by planeur OCtoolguy 1 Quote Link to comment Share on other sites More sharing options...
OCtoolguy Posted March 3, 2020 Report Share Posted March 3, 2020 I watched Matthias Wandel's video again today and he cuts his gears using an inverted jig saw. What we cut on our scroll saws come out much better and far smoother. Quote Link to comment Share on other sites More sharing options...

His creativity is very impressive. I use the Olson 2/0 reverse 28 TPI for all of my precise cuts. It is a slow cutting blade making it very controllable. I have also recently used the Pegas 28 TPI blade with no reverse teeth. it cuts faster bout leaves a bit of fuzz on the bottom side that I gently take off with a mop.

Big difference between what he cuts and precision clock gears. I am really looking forward to making a clock. I might cut some practice gears just to get the hang of it. Do you have any suggestions as to what clock would be a good choice for a novice clock builder? We have no wall space so I guess I'm limited in that respect. But, if I do an exceptional job, I might get a spot somewhere in the house. Quote Link to comment Share on other sites More sharing options...
planeur Posted March 4, 2020 Author Report Share Posted March 4, 2020 I just found the web site of the sanding jig of Ronald Walters, for the wheels, and that I will put on my Ridgid sander. Thanks a lot Ronald planeur Rolf and OCtoolguy 1 1 Quote Link to comment Share on other sites More sharing options...
Rolf Posted March 4, 2020 Report Share Posted March 4, 2020 planeur, I like his sanding jig design. The one I made was a quick "down and dirty" as I didn't have a lot of time to build the clock for the article. If I do another I will certainly build something like this jig. Ray, all clocks have their challenges, I have built three. The first was a weight and pendulum driven, I hung it on the dining room wall, the other side of it is our bedroom. My wife came in and said to come listen to the clock. the wall was acting like an amplifier. The clock went to Fox Chapels office. The Second clock was the "Flying Pendulum" clock, it is spring powered. A fascinating clock to watch but a challenge to build. The third was the "Electromagnetic clock. it is battery powered. and the easiest to build in my opinion as the gears don't mesh. But it also has some challenging bits. They all require patience and precision. But having said that, the first time you see one you built running is incredibly satisfying.

I spent one winter cutting and assembling the Ascent clock. Unfortunately, it doesn't work, but still was/is an awesome project. However, I have every intention of re-making it. Also, Jeff is really good to work with. OCtoolguy 1 Quote Link to comment Share on other sites More sharing options...

Question: how do you make the hour numbers on your clocks ? Have a good day! planeur On my first clock I just cut out the numbers on the scroll saw. On the flying pendulum clock I did a beveled inlay. My mistake was using aspen for the numbers, which was way too soft. Holly would have been a much better choice. For me to say that was a challenging inlay is a bit of an understatement. Edited March 5, 2020 by Rolf OCtoolguy and planeur 2 Quote Link to comment Share on other sites More sharing options...
