This is looking very intressting, keep on good work :clap:

Very nice looking build you got going there, Al. I, too, have a keen interest in solenoid engines of the hit n miss variety. One of the issues I've noticed with all solenoid hit n miss engines is that they don't make very many revolutions between "hits". I think the secret to making a good running hit and miss solenoid engine is to drive the solenoid at maybe double or even 4 times it's rated amperage. Since it is only operating maybe 20% of the time, it shouldn't overheat. However, yours may run perfect right out of the box so would only try overdriving the solenoid if you're disatisfied with the way it runs.

Stilldrillin: Wreckage is correct. Some times you just get lucky

Rob: You are correct, I learn something every time I pour and sometimes I relearn what I did wrong the last time!

Chuck: Yes I hope the heavy fly wheel I intend to use will let it coast awhile before it "hits" again. This whole thing is just an experiment so I have no idea if it will work like I want it to or not.

Now that I have a bed casting - time to move on:

When I built the building my shop is in I never intended it to house a rather tall mill, so I put a simple shed type roof on it. When I bought the mill and moved it in, it was a tight fit, in fact after I insulated the roof the motor was trapped.

It didn't really bother me till I need to move the ram on the mill for this project. So I had to take the time to build a tunnel to traverse the head out.

The reason was to get some head room for some operations and boring on the engine base. I wanted it to hang off the edge of the table on an angle plate.

First drill and ream for the cylinder guide rods:

Drill and bore the cylinder mounting hole:

Fly cut for the solenoid tube mounting flange:

Drill and tap the tube mounting flange screws and cut the guide rails to length. The guide rails are held in place the tube flange.

The solenoid coil sides on the tube and is held on by it's original nut. I also drill some holes for the wiring connections which will have to be insulated. I'm hoping to have no exposed wires:

The results so far:

Calipers for scale:

That's it for now - more fun to come..

Thanks fro viewing.

Da_Kengineer_Meister: Hey, I was up in your area last week - Kent, WA. for a business meeting. Yes, I was worried about the bit wandering off. I even bought a extra long centering bit, but it really flexed when I tried to start the second hole because if the angle. I ended up using the next smaller bit I had than the hole size I needed and slowly let it rub in. Worked out just fine.
