New oven ideas

[Appalachian Hillbilly]

Ok, after being out of the shop for over a month, it is time to get back at it.

One piece longbows are on the menu so that means a new oven. Batting around several ideas. Incorporate it into a new workbench with an under the bench design. Over the workbench  and use the bottom of the oven to have brackets and hangers for my common used tools and a work light  or an upright oven to put in the corner.

Either design will be well insulated and designed to make use as easy as possible.  Drawer slides and racks if needed etc.

Looking for alternative heat sources such as base board heater etc to make space more usable.

Mine is mounted on the wall with storage above and below the oven.

Door drops down easy to load. I like it!!

Make it so you can load it easy. Mine is on the floor and it is a pain to put the bow in.  But it slides under a bench when not in use.

I'm thinking a folding foam box and just leave the form on the bench and set the foam box over it. Maybe a center divider for TD limbs. Just need to figure out a heat source.

The floor models are a pain to get the form in and out of.

Mine is on the wall and opens up, with that stick holding it up I can use it like a table or I can open it all the way up with a hook on the wall and its easy to load. My shop is very small so it works good for me.


Here it is with it open and I do all my glue up's here, plenty of room to lay out all the lams.

Those front loading wall mount boxes are nice

If I were to build another, I would laminate rigid foil faced rock wool panels onto 1/8" plywood and make it  knockdown unit. A modified baseboard heat element or circulating hot air blower for heat.

[Appalachian Hillbilly]

Great ideas guys. Right now I am leaning towards an above the bench, front  loading, gas shocks or springs on door to hold open, and maybe a baseboard strip heater with an Inkbird controller.  Well insulate it and make the underneath  to hang tools on.

Got a little money from another job to spend on this, so I want to do it nice.

[Kirkll]

I like the looks of those inkbird controllers  

If i had to do it again i think i'd just use a couple 500 watt halogen light fixtures and possibly a small squirrel cage fan for heat circulation.   cost effective me thinks....    Kirk

I used a 250 W red brooder/heat lamp when i raised my chicks this spring. Almost bought this instead

Pros,cons what do you all think?

[Buggs]

The nice thing about using a heat source other than incandescents(UGH) is, anything is more efficient and you can shrink the size of your oven substantially. Between the fixture and the bulb you need 6" or more of head/side room.
Thats a lot of wasted shop space, space to heat and materials. For a bow sized box, 100watts of halogen puck lights is enough, or 300watts of baseboard element. They are both low profile options.
A fan is a very efficient addition. Anybody who has cooked in a convection oven, knows how hot and fast they work compared to a standard oven. A little 4" fan will supercharge your box.

That heater is probably not the best choice. It's radiant, which is not for space heating and its got a big footprint for only 140watts.

[Stagmitis]

Makes sense Buggs! Electrical is one thing in life thats beyond my understanding 

[Kirkll]

You've mentioned these 100 watt halogen puck lights a couple times Buggs. I'm curious what they look like, and type of fixture used to plug em in , or are they screw in bulbs?   Got a link to something? 

I'd like to build a small box with a couple 100 watt bulbs to heat my boat in winter storage when it gets real cold.

[Appalachian Hillbilly]

Here you go Kirk. You can get them up to 200 watts.

Those emitters are great! I've got one in my pump house to keep things from freezing. But actually I was referring to these;

The great thing about these lights is that they, like incandescents are also very inefficient and put out a lot of heat.
And they are cheap! And they come with little parabolic dishes! Four 25watt pucks easily match 300-400watts of space hog bulbs. Just make sure to get ones with metal housings, I melted some plastic ones. They run on DC and have a mini inline transformer, so they are typically plug and play.

Hillbilly, something to consider if you are upgrading to an Inkbird controller. The PID will cycle on and off hundreds of times , maybe more, during a multi hour cure. Thats a lot of stress on a light emitting filament. Baseboard element would hold up better in that environment.

[Kirkll]

So the bulbs are replaced like this fixture and can accommodate from 18 watt to 135 watt bulbs?

I’ve seen them with dimmer switches too.

So are you saying that the off/on cycling used in a hot box with a temp controller is hard on these halogen bulbs? How is it any different than an incandescent bulb?

[Buggs]

It would be hard on any "light" bulb that has a filament. Not sure about using one of those ceramic emitters with a controller, but an electric baseboard type element holds up to the prolonged on/off cycling.

[Kirkll]

I was thinking those base board heaters would be much more expensive to run. I know trying to heat a house with them will run you into the poor house.

I'm going to order a couple of these halogen pucks and try them out in my spray booth and see how they compare to the 150 watt incandescent bulbs. I really like the low profile fixtures.

Bugs, I already use an Inkbird controller in my current oven that uses incandescent lights.

It does not rapidly cycle them at all. You can program the delta T and how much you want it to swing. You can even program it to do it in steps. I have it paired with a timer as well.

I also use heat 300 water heat lamps and not lights. You get more heat than light.

A baseboard would be compact but may not be as responsive as pucks or lamps.

It has a timer function but I do not want it to repeat every day . They are worth every dime.

If there is no hysteresis in the circuit , you can get the rapid cycling. I also have mine insulated pretty good.
