Yea, me too. My next project from his plans is the gyroscope. I'm trying to get my gran daughter (15 yr. old) something of interest to do as she has shown some interest in what I do in the shop/shed.

I love it. That one is in the stack as well. I'm sure there's as much dust as there is paper on the clipboard by now.

I have this idea to make one using an automotive disc brake as the main ring, and use serious compressed air to spin it up, but I haven't found one small enough for my 10" lathe yet...

I've got a couple of old brass bearings from a rotary airlock valve housing. I thought I would try to use those. Smaller than a disc brake but the size I was thinking. About 3" diameter.

That's cool. I love the idea of making one with repurposed parts that you can still tell what they originally were. That and I want to experience the resistance of that much rotational inertia.

I also want to do the finger plate in one of Clicksprings videos. No matter how many hold downs and fixtures I have I always don't have the correct one. Also want to do the rope knurls and the tool for shaping the knobs for the rope knurl. Just have to get off my keester and buy the tool steel.

I want to make his filing machine. I know there's a kit out there (just the castings? I forget), but if I remember correctly it didn't seem like a good value if you have the ability to do your own casting and machining, as I now do. Skills are another matter, but I've never let that stop me from trying.

The apron on the Summit leaks somewhere, (trying to find where AGAIN). Tried to remove the sight glass to see where the oil level was, it crumbled, (may have been the leak but think I would have seen the oil streak). Made one and had Julia cut me a glass disk. Sealed the disk to the tube with a bit of RTV.


Installed

Removed the guards to check the back of the apron for the source of the leak. Guess I'd never bothered to check the lead screw. Quite a chunk of steel. 50 mm dia and 2 tpi. Guess it needs to be pretty stought to cut 1/4 tpi, the coarsest setting on the quick change.
Of course I've never had a need to cut anything that course. Would you cut that with a conventional form tool or set up a milling device of some sort?

I made about 20 fire pistons close to 30 years ago, made them out of brazilian rosewood and 1.250 OD, makes it easier on the hand when you smack it, remember the compression ratio must be 18-1 for best results. I made my char cloth out of old american made flannel shirts wrapped in Al foil and set in the wood stove close to the door. I made the bottom threaded with a cap to hold the char cloth with a wick on the one side for a wetted wick for some kerosene and would touch the char cloth against the wick in the middle before installing on the piston, worked every time.

looks right to me...
