Great article Glen. I have seen some of your work first hand and it was first class 15 years ago on a SAW boat I purchased. You’ve been continuously honing your skills since. Awesome 👏 I think you’ll appreciate my new shop toy. Still setting it up👍

Following from the UK. Definitely want to run at Valdosta in the future. Keep it coming please. 👍

Not much in the way of good boating lakes here anymore :( so spending my time machining little engines. Honda GX 160 1/3 scale.

Eagletree has closed its doors. No longer in business.

Happy Birthday Henry. It was great meeting up with you again. All the best wishes 🍻

Interesting project Dan. I'm sure the guys building are well up on this but just in case don't forget to bring up battery temperature and its effect on getting the best performance out of these batteries. It was somewhat of a pain having so many separate batteries in our boat but it was good to...

I remember backing away and hiding behind the aluminum plate at 25K +. I think we were both very careful!

Amazing improvements in chart plotters. The new one just purchased weighs in at about a tenth of the old unit with many more features. Simrad! Of course I had to build a model. My Covid project. Built as a one off but someone's talked me into taking a mould. Original scaled to 1/8. I'm sure it...

For anyone into Big offshore this was us racing in Poole, (Uk's Southcoast) a few weeks ago. Also GoPro 360 footage. . After 10 years I think we are finally getting the hang of it. Still hurts though! I'm sure Lohring remembers. 👍 Each engine burn 325lbs of fuel per hour wide open x 2. At...

. Sounds good in theory. Thanks

That sure is looking sexy!

Just for reference and maybe to get the creative juices flowing here is a one way bearing off a Honda 750 motorcycle electric start. It never gets disengaged so is in overdrive mode whenever the engine is running. From the design it looks like (maybe) it could throw the rollers out of contact...

I did find a video of one of our Zenoah engine dyno runs. Too large to upload though. Will see what I can do to correct that. I did time the run and from 8K TO 19K it was 11.7 seconds. That was with a 19lb wheel I seem to remember. Here's a screen shot of the graph.

The Dolphin glaze is never far away. Good stuff!

The pre speeding of the inertia wheel could be made into an automatic feature that always keeps the wheel above a preset RPM. This being a fix for the particular problem of matching inertia wheel mass for on and off pipe situations. The reason we were burning pistons in my opinion is the engine...

Yes come to think of it I have seen keys on the outside of the bearings used on multi speed RC car transmissions. It looks like on those (taking into account the gear ratio) get overdriven at about 10 TO 12k.

That V8 is awesome! Always been a dream of mine to build one. A massive undertaking though! Maybe the next engine! Interesting on the race slipping. Don't shoot me down in flames! lol. Bearing mount Loctite? Lots of surface area!

Beautiful job Rudy has done! The engine I am building is similar but simpler in design. . As you probably noticed the crank is only supported at the ends, its a pretty stout piece though and compression is low. I purchased the Myford a few weeks into Covid. The Seal Major castings were purchased...

Everything looks good up to about 13500. and you are nowhere near the torque limit on the clutch bearing. Does the clutch bearing have any kind of rpm mechanical limitation? The kart dyno has a one way bearing but the most it ever see's is about 3000rpm. One of the reasons we did not include a...

. 8 to 12 years old and looking to Formula one.
