Experiments on plaster

My first goal when experimenting with the plaster was to find out how well it retains the shape of the mold it was in. I used an old half gallon milk carton, and surprisingly the plaster picked up the majority of the details, down to the little bumps in the plastic. There were no bubbles in the mold either, because while the plaster sets you have to tap the sides of the mold to help release any trapped air.
My second experiment with plaster dealt with using carving tools to forge a shape out of a small block of plaster, and seeing what kind of detail i could get and keep on the surface of the plaster. This worked out really well and was actually surprisingly easy. The plaster is alot easier to shape when there is still moisture left from the mold, as time goes on and the moisture dries out, the plaster is more likely to crumble. I would say if you wanted to carve something, do it sooner than later after it comes out of the mold, as the moisture definitely makes it easier.My final experiment with plaster was trying to get 2 separate pieces of plaster to attach together, using some kind of adhesive or the plaster itself. Adhesives failed, i tried hot glue, elmers, even apoxy, and all just flaked off after drying. The plaster also didnt work, it just didnt have the strength to hold the two pieces together. So ive concluded from this that if you want 2 pieces attached youre better off making a mold with the two pieces already combined.

Carolyn's First Final Model Attempt
Here is my first attempt of my stained glass candle holder and the drawings that I based it on. I have very mixed feelings about it. The corners are still not right and therefore it is not something I can hand it. I am still pretty proud of it for my first attempt at making a stained glass object. I hoping that when I figure out how to do the corners right I can try to salvage this model, but I am not sure that’s going to be possible.
Mike Hummel's Progress
So today I started making the rack with making some cuts on the chop saw and doing some welding and grinding to make the joints. Here is my rack so far:It's a little hard to see but bsically it has 1" square tubing in the shape of 'C's on both sides and two .5" tubing running the length of the rack where the instrument will sit. I also made two little stoppers by bending sheet metal and welding it to the rack. These will hold the instrument in place since my rack is angled downwards. It is hemmed at the top so it doesn't cut my wrist when playing:
Weds. I will be bringing in my digital piano stand to do some drilling for bolts that will attach the rack to the stand.

Experiment
The first experiment I did was with the vacuum form. I took one 12"x12" sheet of 1/8" acrylic and attempted to form it over a piece of yellow foam. With 3 trials the heated to the point where it sags down in the middle, when I release the pressure and let up the form the acrylic didn't get sucked down around the yellow foam. Although I was unsuccessful I found the acrylic to be easily molded (and very hot).

Final Project: Fiber Glass
I plan on making an enclosure for my speakers in my car for my final project. Many people use fiber glass for this because it is very strong and can form to almost any shape. I have two 6x9 that will be installed into it and once this project is done i plan on installing it in my car. I will take the current cover out of my car to get he measurements and then create a form out of blue foam. Once i have the form, i will sand it and find the exact location of the speakers. Once i know that the speakers will fit, i will test it in my car to make sure it fits there. After everything is fine tuned and everything fits i will start the lay up. I plan on vacuum bagging this because i want it to be as strong as possible. I will be laying the 12 layers because that gave me a very strong form in my experiments. Also, i will create a form that doesn't have many complex sharp edges because they were tough to work with during my experiments.

Final Project Proposal :Wood Veneer
Wood Veneer Experimentation
For my first experiment, I tried something that I really did not expect would work. I wanted to see if the veneer would be flexible enough to wrap smoothly around a dome shape. I purposely picked a very warped, flawed piece of walnut burl to see what the limits were. Cutting veneer in anything but a straight line is very tricky, you have to be really careful and give yourself an allowance. First I hacked at it with a cheap circle cutter and you can see, it wasn't too successful:
The glue gets liberally on both the veneer and the substrate, then dries (it takes a while, at least 30 minutes to an hour), and works best with two coats. It is water soluble, and looks like really thick chocolate milk. I ironed the veneer to the dome with a paper towel between the iron and the veneer. It was necessary to give the piece a lot of steam to make it flex, but the steam worked much better than plain water. Its still pretty bumpy, but once it is sanded down it looks good considering how it started out:
For the second experiment I decided to see how well a piece of straight grain veneer can be wrapped around different angles and curves. I heard that straight grain is easier than burl if you bend parallel to the grain, but because the glue I used was waterbased, it did not work at all with the first type I tried. The veneers were not labeled, but I think it may be ash. Apparently this wood is very porous and the glue I used was absorbed into one side of the veneer and not the other, causing it to curl and crack beyond repair regardless of whether it was taped or not. If I were to use it in the future I would use hide glue or contact glue.
The veneer cracked even more when I ironed it to the shaped piece.
Next I tried adding a color with clear varnish, and just clear varnish to the different woods.
The veneers were really fun and versatile, and I hope to work with them a lot more in the future.
