Comment on LED Caving Lamp – Adapting an “Oldham” Caplamp by John Riley

John Riley — Sun, 18 Mar 2012 01:52:32 +0000

I thought you might be interested, I bought one of the first Apex 2 caving lamps that come on the market, the reason I went for the Apex and not the FX 2 was the Apex used the Oldem cap lamps and I felt they were more robust then the FX 2, after all these years I am still getting in excess of 8 hours light from it.

I thought I would share that with you.

Regards.
John Riley.

Very nice, well done. Was contemplating between using word or powerpoint when i came across this on the web. Saved me loads of time. Thanks

Comment on How to Make and Use a Split Bush (Chucking Piece) for Concentric Turning by Adam

@michael – yes, I would always bore a larger chucking piece as you say.
The case in point is a bit on the small side, though (1/8″)…

I think an important parameter is the eventual tailstock excentricity versus headstock when drilling /reaming the bush. So a better practice is to BORE it (single point boring) to guarantee the concentricity with the outer diameter.

Comment on Death of a Corsa (1.0 Twinport) by Adam

The corsa is finally back on the road with a recon engine bought on ebay from Charlie Smith. I can fully recommend him – very helpful and accommodating throught the whole transaction and he went out of his way to resolve a problem with ancillary part tolerances. It runs as sweet as…

Comment on Building an Orrery #1: Looking for Plans by Joe

Yes, I have seen that link and it is interesting. I’m leaning more to something like his Copernican planetary orrery plan. However, the moon does not rotate around the earth in that particular build. You have perhaps seen this http://www.grand-illusions.com/acatalog/Orrery_Kit.html. This is pretty close to what I’m wanting to do, but with gears and/or a chain drive. You are correct in that wooden gears allow leeway and “tweaking” with sandpaper and files to get everything running smoothly. I ran the whole thing by my brother (a retired aerospace engineer) on the phone this evening and he said “you usually just look it up in tables”. But that takes me back to my earlier post (read “dumb” musician) and difficulty understanding the mathematics.

(with some hesitation since I am still to start actually making one)
I would have a look at the Ferguson Orrery.
It seems someone agrees – http://lisaboyer.com/Claytonsite/mechanicalparadoxpage.htm
The Ferguson sun/earth/moon is irritating to an engineer since the tooth shapes cannot all be “proper” but with a bandsaw you should be in a better position than with standard cutters.

Cheers, Adam

Hello Adam,

I too am trying to gather info to build an orrery. I’m a woodworker so I’ll be using bandsaw cut wooden gears. Alas, as a music teacher (we only generally have to count to four; well sometimes 5, or 7 for Stravinsky and the like) the mathematical calculations are beyond me. I want to build just a Sun, Earth, Moon model showing the correct rotation of the earth and the moon around the earth. What possible compound gear ratios could I use (trying to avoid tooth counts over 60 or so, and less than 9). I did try to download your calculator, but this failed. Any help would be appreciated.

Hi Catherine – thanks for your comment. I made another batch this week with this season’s chillies and it came out good again.
Hope it works for you.
Cheers, Adam
