Welcome to Jon’s Machine Shop!

April 3, 2022:  I’ve made a relatively large re-arrangement of the site. Over the last few weeks, I’ve changed some of the menu items. Antique power has been removed from the menu. It is now at the top of the metal projects page. I’ve added a McCulloch chainsaw page to antique power. I’ve also added video of the Poulan chainsaw running with its shop-made connecting rod.

The resin casting tab has been changed to 3D Design. That more completely encompasses the whole process and includes not only design, but also 3D printing and casting. I’ve also added a Graphic Design tab to display projects done in Inkscape.

I’ve added three new pages to the projects page. I’ve recently gotten interested in repairing Starrett Last Word indicators. I may have gotten carried away. I’ve also gotten into oil burners. That’s what heats the house and HVAC companies in this area no longer have any idea how to work on them. It’s clear that people don’t repair things anymore, they just replace. To that end, I acquired a used Beckett burner to play around with. Turns out, they’re pretty simple and fun to work on. The last project added was new clamps for V-blocks. The last time I went to use them, I pulled the original clamp apart by just hand tightening it. I modeled it in Fusion and had it 3D printed in steel by Shapeways. I’m really happy with the way they came out.

Over the last few months, I’ve added new materials to my 3D printing capabilities. In addition to PLA, I now also print in ABS, PETG, TPU, and Nylon. ABS and PETG are similar to PLA, but more durable. TPU is very flexible and tough. Nylon (actually using string trimmer line right now) is somewhere in between. More rigid than TPU but flexible enough to bend somewhat instead of being brittle. The picture above shows the Upshur connecting rod printed in the different materials.

I’ve got a lot of glass projects in the works. Pics will be up after Christmas as some of them may be presents.

The Upshur engine is still in process. No progress has been made since the last update though. Machine work has slowed while I worked on glass projects.

Another project still in the works is a lawnmower lift. Essentially a long set of ramps that once the mower is driven on, will be jacked up in the back. The whole mower will fit on them and when lifted, will be about a foot higher. Basically, a scaled down kwik-lift made out of a 2 by 8 and a piece of pipe. I’d like to gain enough room to be able to use an impact to change blades. We’ll see how this works out.

I’d highly recommend Carbide Tool Source for carbide end mills under 1/2 inch. Fast shipping and really good prices. Not to mention they’re made in the U.S. I’ve added them to the links page.

More to come.

As always, check back often for updates.
