Hi, I need to modify the dwell on a cam on my Scuderi cycle engine that I built. I need to have the intake valve stay open for about 10 degrees longer so I would like to build up the lobe a bit. I no longer have access to a milling machine or lathe so making a new cam is not an option. I was...

Can any one recommend a finished carburetor that will work on my 1/4 scale Galloway engine? The mixer that I made for it is very unreliable and I am thinking of replacing it. Thanks, John.

Hi, I have completed Jan Ridder's scuderi cycle engine. As of yet it will not run except for a few "pops" here and there. I am fairly sure that the problem is low compression. This engine uses no rings and relies on a very close and smooth fit between the piston and cylinder. He suggests no...

Hi, I'm just taking a long shot here, but I am looking for a set of outside jaws for my Buck chuck. It is a 6" adjus-tru, 3 jaw chuck model 3634. Nothing on E-Bay and I really don't expect to find them. You never know. Thanks, John.

Hi, I was looking at the replacement ball bearing, reverse tumbler gears that they sell on E-Bay. They claim to make the gear train a lot quieter. My South Bend 10L is pretty noisy, and I was wondering if any one has installed these and if they work as claimed? Thanks, John.

Hi, I have a mint South Bend 9A with loads of tooling for sale. I am asking 4,800 for it, but will consider a reasonable offer. Photos and a list of the tooling can be seen at the Hudson Valley,NY Craigslist / tools. I apologize, but I don't know how to create a link for this posting. Thanks, John.

Hi, I am looking for a set of used 5c collets that are American made. Idealy, 1/32 to 1 1/8 by 32's would be be best. Thanks, John.

Hi, I built a small check valve as part of a Jan Ridders designed engine. The valve seat was cut with a small boring bar at 45 degrees. It then uses a 3/16" steel ball to make the seal. There is no spring pressure on the ball. In any event, the valve leaks. I noticed that there are tiny...

Hi, I am attempting to fit a 5/32 1018 valve stem into a 5/32 reamed hole in a bronze valve cage. No go, so I have to adjust some thing. I would like a tight sliding fit for the engine that I am building (Jan Ridders Scuderi cycle engine). It is important that this fit is tight as this...

HI, I assembled some small fittings using 50/50 soft solder. This turned out to be not strong enough and the parts failed (came apart). I plan to use silver solder next, but these small parts are still tinned from the lead solder. It is not possible to remove this tinning without making new...

I bought this piece of 1/2" aluminum plate on eBay. It has this pattern on one side, and the other side seems to be just a mill finish. Does anyone know what this pattern means? Thanks, John.

Hi, I am putting together a brass gas tank that is 1 1/2 inches in diameter. I would like to make one end out of glass. I am wondering what would be the best way to glue the glass to a brass ring that would be soldered to the tank end. I was thinking of silicone, but I don't know if it would...

Hi, Is it possible to substitute non detergent motor oil of the proper weight for the oils that come with the kits from eBay? I was thinking of 10W non detergent for the type "B" oil. Thanks, John.

Hi, I have been interested in learning something about 3-d modeling. The software is expensive but I was able to buy Solidworks 2019/2020, student edition for $20.00 as a veteran. Not being very computer savvy I didn't realize it will not work with Mac OS. Do I have any options other than...

Hi, I have a Vertex rotary table with an MT3 bore. I would like to use my ER40 collets to hold work on this table. I saw on E-bay a Shars CNC milling holder that took ER-40 collets, and had an MT3 taper on the other side. Do you think that this would work on my table without using a drawbar to...

Hi, I have a Vertex 8" rotary table with a MT3 center hole. I also have a South Bend 9 inch lathe. I would like to use my 3 and 4 jaw chucks, which have 1 1/2 8 backplates, on the table. I also have a very used South Bend 9" spindle. Do you think it is possible to cut and turn a mt3 taper on the...

Hi, I am attempting to turn a flywheel from 1018 hot rolled steel. The finished dimensions are 4.25" diameter by .750" thick. I bought this grade of steel because it was half the price of cold rolled. I have never tried turning hot rolled before, and it has been a nightmare. It is chipping the...

Hi, does any one know where I can find the plans for the original Chuck Fellows carburator? I heard it was in the downloads section, but I can't find it. Thanks, John

Hi, I am trying to lap a 12L14 valve into a cast bronze seat. The valve is 5/16 inch in diameter, and both the valve and the seat are cut at a 45 degree angle. I am spinning the valve with an electric drill, varying the speed and using an 800 grit lapping compound. The valve has seated very...
