I made a cylinder liner and pressed it into the cylinder using Loctite #638. There are holes through the cylinder and through the liner. Before drilling through the liner I tested it and there is free air flow so the liner is not sealed in the cylinder. My question is what temperature must I...

I have an Excello 602 mill which I am happy with but I keep having a problem with the hand wheel feed on the spindle. There is a tapered brass clutch with a tension adjustment knob which works fine for a couple of months and then gets to the point that it will not feed without adjusting the...

I have tried the Jan Ridder vapor carburetor in the past and have never had any success. I just made a jam jar model and have not been too successful. To be fair I have not been successful with the venturi carburetor on this engine either because of flooding therefore the vapor carburetor. If I...

What should be used to seal a cylinder liner in a cylinder? I have a liner made from DOM tubing in a steel cylinder. It has holes in the side for intake/exhaust/plug. I put it in using JB Weld and it is leaking around the spark plug hole. I am sure that when it is inserted it scrapes off most of...

Has anyone here built an Atkinson Differential using the design by Brooks Pendergrast? I built one using the Gingery plans a few years ago and was never able to get it to run so I decided to try the Pendergrast design. So far it I am having better luck on this design but I am having a problem...

I am confused about the connectors used for the CDI ignition modules for the Hall sensor and the battery connector. They say that they are FATUBA connectors and I have purchased premade cables from Amazon and I am not getting the correct connectors. Apparently there are JR, JST, SYP connectors...

Saw this at the Indiana show last week.

I am confused. Not exactly unknow territory. I have a 13" south bend lathe and I am thinking about making a taper attachment for it. There is a standard feed screw and a telescoping feed screw. Mine has the standard screw. The SB instructions say remove bolt A which disconnects the feed screw...

I just had some gears laser cut from 1/8" brass and they came out very nice. The price was also very good at about $8 each for a 2" dia. gear. There does seem to be a $40 minimum so I have four spares. No connection to them but others may find it useful. sendcutsent.com

I have this ball bearing center which got too close the the tool bit. I would like to regrind the point but I cannot figure out how to get it apart. There is no hole through from the back and the front seal or shield does not appear to be easily removed. Some centers appear to have a front...

I have been thinking about making some tangential tool holders for the lathe. I found this which shows one design. There are many other similar designs. http://theamateurmachineshop.com/index.php/projects/13-tangential-lathe-tooling Has anyone used this type of tooling and if so there must be...

Have any of you 3D printed a steam engine. This came to mind when I was working on the internal gear for Elmer's Geared Steam Engine and it was suggested that the entire engine could be 3D printed. Is this possible to make a working model of this engine? I would assume that some things like the...

I built Elmer's geared steam engine several years ago and have since sold it. It is a neat engine but it has an internal gear which he specifies a 72 tooth Boston Gear. It is super expensive. Is there some way to make this gear? The only thing I can think of is to make some kind of a broach and...

I have built a Comber Rotary Engine and I am having a problem getting it to run. It seems to hang up when the cylinder is about 30° past vertical. This happens on both ends of the cylinder. The piston/rod does not seem to be binding up in the cylinder and the rod forks do not seem to be binding...

Recently I began having a problem with my "Y" axis slipping during printing. I have an ANET A8 printer and I am using Cura 5.6.0 slicer. I recently changed to a newer computer and the problem seems to have started about that time. The old computer was using Cura 5.3.0 and I found a discussion on...

I have a 1:12 scale lathe and drill press. I am thinking about making a diorama running these and possible others run from one of my steam engines. My question is what have folks used for the belting to run the machines and the line shafts? PM research offers belt per foot but I am wondering if...

I am trying to run a Corliss engine on compressed air using an airbrush compressor. My question is what am I missing in my calculations? The engine has 1.125 bore x 1.5 stroke. This calculates to 1.49 ci/stroke. Since it is powered both directions it should use 2.9 ci per revolution of the...

Has anyone used an aquarium pump to run a small steam engine? I am talking about something with 3/4" to 1" bore. My daughter teaches middle school and one of the sections that she teaches is the industrial revolution. She wants to show them a couple of examples of running engines and she would...

I have just completed the building of the Duclos Odds & Ends engine. I have it running making it pretty much per the original plan including the carburetor. I had trouble getting it to run unless I partially closed the carburetor intake. I ended up putting a restricting tube in the end of the...

Does anyone have experience with the import milling machine vises? There are pretty impressive looking 6" vises available in the $100 to $150 range. I realize that they do not compare favorably with the $600 Kurt vise but most of us home shop hobbyist have a hard time justifying the price...
