I have used the miniature plugs with propane and they seem to work fine. I also had a problem getting it running after the first time. I found the cams had slipped on the camshaft. I ended up putting larger set screws in the cams. #3-48 instead of #2-56 and the larger hex allowed more torque on...

Are you testing it in the fuel you will use? Might float differently than it you test in water. Just a thought. Doug

I find it difficult sometimes to switch from "metal tolerances" and a caliper or micrometer to "wood tolerances" and a tape measure. Doug

They are predicting up to 160,000 people coming to Northern VT for Monday. Total population is less than 650,000. I'll be on top of Sterling Mt. "working". Prediction is for decent weather. Doug

Lloyd, Sunsets may be even better. They are over Lake Champlain with the Adirondacks in the background. It’s a fine state we’re in. Doug

On my way to “work “. I Ski Patrol a couple of days a week, l guess we’re going to get some snow later today . At least this time of year it doesn’t last long. Doug

Loyd, Snakes don't seem to be a problem here, and the only one we've put a "cat baffle" on was at my daughter's. She has a large, active cat who thinks he's a dog, but still chases birds occasionally. We put that one up a little late last spring, and the Tree Swallows appropriated it in less...

"Oakenstrong" sounds like a character out of Tolkien

I finished up a few Bluebird nest boxes this week. Two went to neighbors, one still looking for a spot. We’d been seeing Bluebirds checking out the box in our yard, now we’re having what looks to be the biggest snow of the season. Always hard to change from metal tolerances to wood tolerances...

Minh Thanh, That's about how I did it. I shortened up on the drill to make it stiffer, and I think that helped. Doug

Alan, Thanks for the pictures. I really like the riveted assemblies, both here and in the traction engine (wheels particularly). The track pads had to be a chore, but it all came out well. Do you make your hardware? Doug

When I'm done with plans (I work from a copy of course) the back of each page is filled with notes, and other things explaining to myself how I'm going to make those parts. Some is steps, some is DRO spacings/placement. They aren't quite as step by step as your photo above, but why not if it...

I'd like to see the CAT models. Your Fowler BB is beautiful! Doug

Andy; Thanks for changing back.... it was all Greek to me ;). Doug

You could fit a restrictor if the 6mm carb turns out to be too big. I did that to make my carb work with propane.https://cdn.imagearchive.com/homemodelenginemachinist/data/attachments/93/93629-f5afb0331e659ac29e151098d797e8fc.jpg Doug

Back in my winter “office” a couple of days a week Doug

Goniometers are also used for measuring joint angles and range of motion on people.

Ouch! Glad you weren’t hurt any worse! Doug

Almega, I tried exactly that. I carefully centered in a 4 jaw chuck, supported the end with a pad on a live center and tried to turn away the excess. I don’t know if the tube wasn’t round or if it was flexible enough to deform in the chuck, but it cut some parts and missed others. It did reduce...

I have used white-out and it worked ok. I didn't think this would be a problem and didn't consider using it. While something as a mask would have been a good idea, it cleaned up well but was more work than it had to be. Doug
