« Part 6: Slow Progress ......but progress none the less Part 7 of Building Some Chevalets, a Class Action series Part 8: More To It Than Just Pretty Chevalets »

Just a bunch of photos from the last few days to bring the project up to date. When I left off I was about to make the saw frames and the clamp springs. That went quickly.

Then I got a little sidetracked on adjustability of height for students of different statures. All of the chevys I have built have adjustable arm height by re-arrangement of graduated thickness shims, tightened by matched wedges …....

.....but in the past adjustment was infrequent and the re-drilling or replacing of the sacrificial clamp jaws was no big deal. I wanted these to be easy and accurate to adjust so that when the arm was raised or lowered, whether by an inch or just an eighth, the jaws could be matched exactly and quickly. This was my solution.

The last one shows the range of adjustment, about two inches per chevy. With one tall, two mediums and a short I can cover 20” (~21cm) to 25 1/2” (~65 cm). Then there is my existing 65 cm one as well.

I’m not quite there yet but I’m definitely getting closer.

Thanks for looking in.

Great work, Paul. Innovative brain work on the adjustability issue. But, Couldn’t just have made the seat adjustable? Or stock up on some phone books? I’m a simple man.

You are a master tweaker Paul. I love your clamp jaw solution. Good progress, soon you will need only students sitting on those beautiful new Chevys to complete the project.

Your solution for height adjustment looks real nice. Thanks for keeping us updated on your project. They are looking more like Caddy’s to me, not Chevy’s.

Paul, I’ve been following along quietly, but feel compelled to chime in – - : ) You are undertaking a great project, and all of it “the journey” The class is going to be the frosting. I just finished gearing up to teach my first box making class, so I can relate——somewhat : ) Anyway, keep up the good work, and thank you so much for the posts, it is interesting to follow along.

Thanks everyone.

Mark, if the seat height changes the tallest person will have the shortest seat to foot position distance and the shortest person will have the longest seat to foot position distance. This seemed to be a better way to go …...... to me anyway.

Mike, I haven’t any students for the August course (not a surprise – short notice) but I have two already for the Sept. one. ............ Have you ever visited Victoria in the fall? ........ It is lovely.

Charles, I may sell the odd one to a student but it isn’t really the plan to keep building them.

Another innovation on the height adjustability! Well done Paul. They are looking great.
