Gentlemen, I made this fixture years ago and have had to use it to make an elbow fitting for the radial engine I'm building. I thought it might be of interest to some of the scratch builders. It just a mounting plate 1/4x2-1/2x2-1/2 (6x63x63 mm) I then made 2 tiny V-blocks with clamps. One is...

Years ago I built a 5 cylinder radial engine somewhat loosely based on the Morton M-5. When I was honored with receiving the Craftsman of the Year award from Sherline they asked if I might loan of donate something to the Craftsmanship Museum. My donation was my radial engine. In the years since...

I read Terry Mayhugh's post about making the crankshaft for his 289 v-8 engine. While I think it would be more than strong enough given the testing he performed on it I wanted to present my way of making one piece, multi-cylinder crankshafts. Over the years I have made many crankshafts for...

I am a U.S. veteran. That being said I get Solidworks student/veterans version (full) for $20.00 U.S. It is a yearly subscription. Last year everything went fine but this year I submitted the paper work and in a short time got the 2023 CD's. I loaded the program on to my dedicated computer (i...

A good friend who's into rare and unusual engines came up with this. It known as a toroidal swinging piston engine. He asked me if I could make a printed model of it for him. I made all the CAD models and printed them on my printer. The engineering behind it is it has a disc connected to the...

Gentlemen, It was brought to my attention that there is a clearance issue between the connecting rod and the bottom of the cylinder liner. I did a layout and adjusted the cylinder liner drawing by putting a chamfer on the bottom edge. I have tried to send the corrected drawings to everyone who...

Gentlemen, It was brought to my attention that I forgot to put the spring in the governor drawing. I made the correction so for anyone who purchased the drawings please contact me and I will send you the corrected sheet. gbritnell

Gentlemen, When Terry Mayhugh finished his version of the 300 inline six from my drawings and his modifications he was looking for a new project. Many of the fellows on the forum came up with ideas. He kind of settled on making a Ford 289/302 high performance engine. When I built my engine many...

Not wanting to hijack the Black Hills thread I thought I would ask the question here. What's with the Zanesville show? I've been going to the Debolt site for months but there's never an update. It just says email for information. A simple photo of the current show flyer posted on the website...

Gentlemen, I fellow on one of the other model engineering forums built a small ratchet wrench. I liked the idea so I took my 1/4 inch Craftsman ratchet and scaled it by 1/2. The ratchet and the sockets have been living in a ZipLoc bag so I thought it was about time I gave them a better place to...

Here are my drawings for a version of Tiny I made. This is a vertical, water cooled (although it never got hit enough to need water cooling) The main dimensions are the ones from the original Tiny but with my design changes.

These drawings are in the files somewhere but I am reposting them under the 'Tiny' heading so they can easily be found.

Attached are the files for the 'Tiny' hit and miss engine that I made into an air cooled version. The main dimensions are still taken from the original 'Tiny' drawings. gbritnell

Ladies and Gentlemen, I purchased a copy of the book, Build the Snow, from Village Press. In going through the drawings it requires 4 lip seals with a part number of NOK AC8054 -EOS. It also gives references to several companies that apparently handle these seals. I have spent the greater part...

I spoke with Karl Gross at the Zanesville show and he informed me that the NAMES show for 2022 has already been canceled. Bummer! I was really looking forward to going next year. Karl used to be on the board of directors for the show. gbritnell

Gentlemen, I have been following the O ring discussion in another thread and have read several others in the past. Most of the builders on this forum have been machining and making engines for quite some time. That being said I have trouble understanding why there is such an aversion to making...

This thread is to answer a question about split bearing inserts for connecting rods but will cover the making of the rods and inserts. These rods were made for my flathead V-8 engine. They were made from 4140 steel. I could have made them from 1144 but would have had to cut round stock into a...
