Posting on my twin build about finishing with sandpaper got me to thinking about when I was an apprentice. We apprentices got to spend a few months in the metalurgy dept where I worked. We were a bearing manufacturer that used many types of steels in our bearings. We did our own heat treating...

I see Bob's wife Margaret has the castings on sale until 5/31/12. Bobshores.com

This followed me home today. Looks to be a keyway milling machine. After taking pics I gave it a good dose of kroil oil as most parts are froze up. I'll leave it set a few days and when I have time I'll try to get it apart. It may actually be worth fixing up and putting a motor to it and see if...

Seeing that my twin project is coming along well so far I would like to approach the forum for advise or help in the next design. I have been working on a design for a twin cylinder IC engine that is gearless in nature and it uses a cantilever connecting rod. The crankshaft will run in either...

I have recently purchased some tools that I think the forum may like. I received a phone call back in the fall from one of my former co-workers wife. Her husband is in the advanced stages of Alzhiemers and is in a nursing home now. She asked me if I would help her liquidate his tools. He is one...

I know this a bit off topic but I hope you will find it of interest. I had to make some Christmas presents lately and upon completing one of them I was told that it needed a star placed on it. Here is how I went about making a 5 pointed star on the mill. First the rotary table was set on the...

Well, I have finally found some time to start another engine. This will be my first attempt at posting a build here so please keep this in mind as we go. Any helpful suggestions on my posting will be gratefully accepted. I like to build my own designs and I have been thinking about this one for...

Since the subject of building Bob Shores Silver Bullet has come up I was thinking of something that may be of interest. If this has been brought up before, forgive me. I don't remember if I got this from Bob himself, I did get to meet him and talk to him on a few occations or if I read it...

My wife, daughter, son-in-law and myself took a train ride this past weekend. I have always wanted to ride in a train powered by a Shay locomotive and this past weekend I got my wish. This is one of the Shays used on the Cass Scenic Railway in Cass, West Virginia. This is an old logging...

Jeroen's build of the Stuart toolroom lathe has reminded me of some of the retirement gifts that were built where I once worked. One of the fellows that ran a turret lathe, who was very well liked by all, was given a model of his turret lathe upon retirement. The making of the lathe was a...

I happen to have an automatic transmission rebuild going on this week. This is for a car I'm putting together this spring to go racing. The output shaft has a helical gear hobbed onto it for the speedometer drive gear to mesh with. I counted the number of teeth on the gear and came up with 13. I...

Recently I posted a couple pictures of one of my scratchbuilt engines titled Gearless hit-miss. The engine uses a crossover cam to actuate the exhaust valve. I thought I would post how I made this cam. First I should explain its operation. The crossover cam has a groove cut into the OD that...

Last winter I broke the handle of my shop broom in two pieces trying to sweep the snow off of my snowplow. Well now I needed a new shop broom, so while at the store I figured I'd pick one up. They wanted a whole 15 bucks for just a broom so I figured i"d just do without, I'm kinda frugal as you...

I built this scratchbuilt sideshaft hit-miss engine a couple of years ago. It has a 1.25" bore by 2" stroke. The flywheels are castings I picked up at a show and the rest of the engine is from barstock. I bought the helical gears from Paul Diebold (they are from his Vaughn). The frame was made...

Help! I draw all my drawings on a PC thats not connected to the internet. The drawing program I use is TurboCad. What I wanted to do was to download some drawings to a CD, then upload to my laptop which is connected to the internet. I would like to share some drawings by e-mail with another...

Hello again, I thought I'd should post a photo of one of my scratch built engines. I wouldn't want everyone to think I'm a smoke blower. I came accross this idea at the Portland In. gas engine show. There was an engine on display that used a crossover cam design to actuate the exhaust valve. I...

Hi folks, Just me again. While I was on the subject of getting valves to seal properly I though you might like to see how I finish my valve faces. After turning the valve stem and finishing to size, diameter, then I cut the 45 degree valve face with a form tool I ground on a 45 degree angle...

Hi folks, I thought you might like to see how I overcame the dreaded leaky valve seat problem. It always seemed like I was struggling with getting my valves to seal on my IC engines. I decided to make a valve seat cutter by using a piloted counterbore, the kind with removable pilots. The...

Hello, My name is Dave Gibbs. I've been lurking here for a few months now, so I figured I should join. I'm a retired tool and die maker with over thirty years of experience. I worked for a leading bearing manufacturer for 30 years. For my last 10 years of employment I worked in what we called...
