Heres something I came upon.
Ultraviolet A (UVA 315-400nm) is used for low energy UV polymerization reactions in the bonding and curing of various materials, and is also used in non-destructive fluorescent inspection methods. Photons in the UVA (315-400 nm) promote through cure, especially with thicker film layers.
Ultraviolet B (UVB 280-315nm) is used along with UVA for polymerization and since it is the most energetic region of natural sunlight, for accelerated light aging of materials Photons in the UVB (280 - 315 nm) contribute to bulk cure.
Ultraviolet C (UVC 100-280nm) is used for rapid surface cure of UV inks and lacquers, and is also used in the sterilization and germicidal processes and applications, the most energetic of the wavelengths used in UV curing. Photons in the UVC are important for surface cure and promote surface properties such as hardness, stain resistance, and abrasion resistance.

Also checkout Ravenlures link for the safety issues. While UV spectrum is all around us I wondered if looking at the light or building a light box using tanning lights might be a problem if UV lights are used extensively. Tanning salons have eye protection as some exposures are more lengthy than suggested to cure baits. Its probably more hazardous to ones health with using other chemicals (solvents, gasoline,etc.) than UV lights but its probably worth thinking about how you plan to use UV lights and decide if your eyes need protection. I use to work in the chemical industry and safety was always promoted at my company. Your free to do as you wish.

Ravenlures and EdL,
Thanks for the clarification, and for the heads up.
I wound up with pterygium growths in both eyes from working and playing outside for too many years without UV protecting sun glasses. I had one removed, and it was so painful I have resisted doing the other eye for 20 years. Now, with lasers, I'm thinking about getting the other one done, but I'm not very enthusiastic about the prospect at this point.
I definitely don't want any more UV exposure than is unavoidable, and this sounds avoidable to me.
If I wind up trying Solarez, a strong possibility, I'll be sure to wear my UV protecting Costa Del Mar sun glasses when I use the UV light.

I wonder if these light bulbs made for aquariums ( suppose to be good for plant growth etc. because they mimic sun light) would work..I was looking at some at Wally World ...Nathan

I looked at some of the plant lights at Home Depot, but the ones they had there somehow filtered out most of the UV only allowing the range necessary for the plants. However, I did see some at WallyWorld too that said full-spectrum, which should cover the range. I know that a reptile bulb I tried from petsmart (which said it was intended to emit UVA), didn't work to well.

This is for you trig people.
I have two dia. one is 18" and the other is 14" all boards are 1/2" thick how many boards needed, what size and what angle cut at to make each dia.
I put this in homebrew also but this is needed for a light box for curing the lures.

Not quite sure what your trying to achieve. Are you trying to figure out the degree of cut to make a circle out of pie shaped sections? If that's what your wanting to know then we need to know how many sections you want. The diameter of the circle doesn't matter as the degree of cut will be the same on both sizes.

Posted 12 November 2012 - 12:22 PM
Two different sizes one would be outside and the other inside dias.. The number of boards will be determand by dia. and angle.
or am I wrong. I want to make two sizes one fits into the other. Not pie shape.14" and 18" round.
I see your point just wrote it up wrong.
Posted 12 November 2012 - 01:45 PM
I think I stated this wrong each dia. will be with 1/2 inch boards one 14" cylinder and one 18" cylinder dia. it looked like I was saying 4" thick boards. Also the angle needed to cut the boards and how many boards needed to make those cylinders.
Ill get this right yet

The more sections you build it from the closer to a true circle it will be. How close to being round does it need to be? Keep in mind that building it this way it will never be perfectly round unless you chuck it up in a lathe and turn down the corners. Will an 8 sided shape work or is that not round enough?
Not sure what your building, but would it be easier to cut circles out of a piece of wood and then wrap it with something? Think of something like one of the Ferris wheel lure turners with a wooden circle at each end of a axle rod and wrapped with material.

8 sided would work. I may be getting caried away here but when I get stuck on something I keep going till I fall off a cliff. HARD HEADED as my wife says.

What does this have to do with Solarez??????? Sounds like a new topic needs to be started....

@ Brent R
I'm guessing it has something to do with a UV curing box for baits that will interrupt the beam of UV light for short periods of time to give a glossier top coat.
Let me do some figuring and I'll get back to you. It's been a while since I've used these formulas. The angles are no problem. What I'll have to do is break the circles up into sections and figure the chord lengths. Might have to open a book for those equations. Will get back to you.

Yes it has to do with a curing box. And thanks Ben. When I get it done I will post a picture plus the plans.

Wayne you could ask ...Bass100 for some help....he has already built one.......Sorry for being a dumb azzz... sounded like you were building a space ship......

Have you ever seen the really heavy round cardboard concrete forms that they sell in home improvement centers? I don't know what they cost, but they come in the diameters you want and might save you a lot of carpentry work. http://hatchbuilding...ncreteForms.pdf
Posted 13 November 2012 - 12:32 AM
Wayne if I've calculated this right the chord length on the 14" circle will be 5.3576" and on the 18" circle it will be 14.137". The degree of cut for each side of the board will be 22 1/2 degrees. This will give you an 8 sided shape that will be the given diameters where the boards meet.
Maybe one of our resident engineers can check my figures to make sure they're right. I used to do this sort of thing regularly, but it's been quite some time since I've been down that road and a lot of brain cells have died along the way.
p.s. The chord length will be the width of the boards.

Thanks alot Ben. There are many round objects that I could have used. I just wanted to work with wood which I have growen fond of doing since retirement. Time does not matter anymore with me. And if I could build a space ship I would have done that along time ago with the help of my wife who would like to put me in it, I do drive her crazy with the things I come up with.
Posted 13 November 2012 - 12:20 PM
No problem Wayne. Let us know what you come up with and how it works. That is if your wife hasn't blasted you into space yet.
Posted 13 November 2012 - 01:54 PM
Since it sounds like shorter, repeated exposures help retain gloss, why not hit one side of the bait for a minute, rotate to the other side for a minute, and just repeat until the resin is hard?
I know I'm probably missing something here. That sounds too easy.
