Well usually you seal the ends and put the wood in a cardboard box lined with foil and a light bulb inside. Make sure the box holds the heat but vents out the moisture. But you can't really seal the end of a burl, its all end. But I would seal the area that was cut. The drying time depends...

Well it certainly can be done but I would not call it easy. You have to put in a switch that by passes the rectifier and filter section. But depending how the potentiometer is wired in you may need to add a second one to control the AC. In theory you could just use the transformer output with...

You guys sound more like electricians than knife makers, LOL, but the above post is right on. It does not matter what voltage you run it will cost the same, and the difference in current that was measured was probably due to some unknown variable, not the voltage. When you start using motors...

When ever you are cutting scales from blocks of wood you should get them close and then let it rest for a few days before attempting to get it completely flat because wood will almost always move a little after being cut and the internal tension takes time to release. Moisture also plays a part.

I think you should reconsider the purple heart. You can burn it with a heat gun and it will darken and deepen the color of the purple. You can control the depth all the way to an almost black color.

I'm in thanks for the oportunity

Your paperweights will sell just fine I happened to get a five gallon bucket of HC labeled spikes. I made 2 dozen knives had no problem selling them to history buffs and rail road enthusiasts as novelty items. They love em! I have had several people buy them and use them for camp knives. I...

How goes your kiln has the temps stabilized?

Sorry but you still need 220V for this controller to run your motor at full speed. You can run it with 120V but your motor will run at half speed. Or if 220V is absolutely not an option then you could use a 2:1 transformer to step up the voltage. The switch is a great way to control the...

No it does not reverse on its own. But you can wire in a 2 pole 3 position toggle switch in the armature circuit to reverse the polarity. Just don't throw the switch wile the motor is moving or you will blow fuses.

I speak motor:D This is a 180 volt DC motor, the 200/100f are the field voltages and depends on whether you wire the field windings in series or parallel. When wiring most controllers at 110V you will get 90VDC at 220V you get 180VDC. Some thing similar to this WU-70100-10 from...

very nice set up very well laid out. I love the controllers and enclosure. This is really how things should be done. I hope some of the other guys take notes for safety sake.

:confused: Wow a DC 1.5 HP motor should be any thing but easy to bog even with a big flat wheel. I am curious about your controller. Does it have IR compensation adjustment? If so you might try tweaking it a bit. It might be worth wile for you to upgrade your controller. A DC motor with...

Just wanted to add some of what I know about motors, I would like to clarify a few things. Horse power is a measure of work not torque! and torque is what keeps you from bogging a motor. Horse power is a calculation of how much work can be done in a given amount of time. This means that a...

Try checking the set up on the controller, some have adjustable tolerances or ranges. You may need to do some tuning. Another thing to check is your insulation, if it has any cracks or the door does not seal properly you will lose heat very fast. You could also try adding some mass to kiln...

The circuit breaker will protect the heating element and the SSR but a 20 amp fuse wouldn't hurt between the line and the output side of the SSR. I would highly recommend putting a small fuse between the line and the PID. Maybe 1 amp just to make sure that a short or a wiring mistake doesn't...

Ya that reminds me, I should give one more word of advice. FUSES!!! You don't want to buy those parts again.:confused:

Tutorial Sounds like great material for a tutorial! I know its not knife making but others might be interested in building a similar controller for their own home made ovens. Make a parts list and take few pictures to post in the tutorials forum.2thumbs I am exited already and its not even my...

You are right on a 3 phase motor and VFD will cost about the same as a comparable single phase unit. You also get the benefit of variable speed quieter operation and a smoother running longer lasting machine, all in a more compact unit. I go with a 3 phase motor every time good find on the...
