I'm playing around with one of them to see if I can replace the knob with a wooden disc ground into a cam to push one end up the proper right-of-decimal degrees, if it works, I'll do the other timer similarly for below.<br /><br />Same method should work for the other axis, just changing the configuration of the cam.<br /><br />I'm just playing with it out of curiosity. Thanks for sharing your info and experience on it.

That could make keeping anything not solid in the cooking area tough. Matter of fact it would make it hard to keep anything in the cooking area period unless it were actually stuck to the cooking area. You'll probably see that once you start on yours. For now from about 11:30 AM to maybe 1:00 PM is cooking time and any earlier or lated puts the beam out of the target area.

For this wooden monstrosity there isn't much hope as far as automating it. If I were going to go to the trouble of building some sort of tracker then I'd want a much larger lens and would build a completely new cooker on a metal swivel mount and also add the ability to change the lens angle to. Problem is that with the burn ban here I'd have to get a welding permit (Which I need to do anyway), but then I'd also need to move the shower pump to the water tank so I'd have pressurized water to spray down any fires that might start. I'd also need a spotter which I don't have most of the time when I'd need one.tffnguyhttps://www.blogger.com/profile/01830558433596399955noreply@blogger.comtag:blogger.com,1999:blog-8051650307488354823.post-25039498567227251572011-09-09T15:26:12.423-05:002011-09-09T15:26:12.423-05:00tffnguy: I'm probably wrong about this, but a...tffnguy: I'm probably wrong about this, but a simple sun tracker for such a short duration shouldn't be all that difficult and not at all expensive. Just knowing the azimuths of sunrise and sunset would give you the track to line it up, then using a spring loaded cooking timer with the set-knob drilled through for a clamp to attach to the lens and move it should give you enough accuracy for that length of time.<br /><br />But I'm probably missing something. Enjoyed the post. Thanks for elaborating. I'm trying out a different type of lens shooting for more heat.

I just kept trying to improve on it for my use. I'm sure there are a lot of other ways to improve on it, but the main problem is the sun's position in the sky. It changes the focus point in the lens and the position of the light on the grill constantly so the cooker and angle of the lens has to constantly be adjusted. Just during the 20 minutes it takes to cook the dogs I'm sure I have to make adjustments at least 5 times. Leaving it unattended is not wise at all and will probably result in a fire. To really do any good with one as far as cooking goes you'd about need a two axis sun tracking device hooked up to it. I'd suspect that could get pretty expensive, but figure JW will likely do something like that with his new 49 inch lens.tffnguyhttps://www.blogger.com/profile/01830558433596399955noreply@blogger.comtag:blogger.com,1999:blog-8051650307488354823.post-26561664579552019812011-09-09T12:31:13.361-05:002011-09-09T12:31:13.361-05:00Hi tffnguy: Thanks for all this.

A little fiber optics connected to a laser shotgun and I can shoot down turkey buzzards and have an instantly cooked turkey dinner. I like most old cars, but have a fondness for falcons.<br /><br />Dave, it actually works pretty well as is. One this small would never be a party cooker. Now if you want to heat up metal to cook dogs with then that will take a pretty good amount of time so its just as easy to zap the dogs as is and be done with it.

Tomorrow I'll redo it once more to make the platform and sliders hold the grill at the position I want it. I cooked two more dogs with it for lunch (at one time), but it was two dogs cut in half again. Works for me though.<br /><br />It took about 20 minutes to cook them both at the same time and they came out about perfect because it took long enough for them to be heated all the way through. I like it like that so once I modify it tomorrow that will be it.<br /><br />I may see if I can find a small clear Pyrex dish big enough to fit over the cooking area (Inverted) and possibly cut a piece out of the bottom of an old cast iron skillet just big enough to fit inside the inverted dish. Maybe insulate the bottom of the cast iron and see how that works. I also have another idea and that is to put a foil covered bowl under the grill so that the high intensity light that isn't shining on the dogs will reflect back to the bottom of them. That should speed up the cooking time to and do away with having to keep turning the dogs. Just something to play with for now. ;)tffnguyhttps://www.blogger.com/profile/01830558433596399955noreply@blogger.comtag:blogger.com,1999:blog-8051650307488354823.post-2466719697312765162011-09-07T13:44:35.091-05:002011-09-07T13:44:35.091-05:00I think trying to cook the dogs by directly shinin...I think trying to cook the dogs by directly shining it on them is not going to produce the best dog. if you focus the light, the outside will burn before the inside cooks, back the lens off and it is just a slow bright light.
