Waterproof MDF Radius Dishes

We now offer UKULELE sized dishes!(click here)

New revolutionary material for radius dishes...Waterproof EXTIRA MDF. This is a new material that we found to be excellent for radius dishes. This material is virtually waterproof, termite proof, and bacteria proof. This is a huge improvement in material, since radius dishes tend to want to curl and warp with any humidity. We have developed the new STAY-FLAT method for producing our dishes that virtually eliminates the possibility of warping. Because of this method of removing the case hardening of the dish, it reduces the final thickness to .80" thick. See for yourself what the best dishes on the market can do for you!

We sent a set of these dishes to Mark Blanchard of Blanchard Guitars ( http://www.blanchardguitars.com ) for review, and here is what he had to say:

"These new dishes are great! The curves are smooth and accurate and they are flat on the back, not warped like some other mdf dishes I have seen. I recommend these to anyone wanting high quality radius forms." --Mark Blanchard

1. We only use the highest quality materials to build our dishes. There is no one out there selling waterproof EXTIRA MDF radius dishes, so you can only get these dishes through Luthier Suppliers. We no longer apply Shellac to these dishes because it no longer needed since these are waterproof. So why take your chances with plain MDF when you can have the best material and the most stable dish available for the best price.

2. There is no one out there that can beat our price for this quality!

Radius Dishes are used to shape the top and back braces to the radius of your top or back and are also used to glue the top and back on to the sides of a guitar. One of the most useful applications of a radius dish is to create the radius of the top and back on to the sides so that the top and back will fit perfectly with the radius of the top and back, and therefore creating a less stressful joint.

How to Use This Product
These radius dishes are used for glueing the top and back braces on to the top or back using a go-bar deck. You place the dish on the bottom of the go-bar deck, then place the top or back on top of it, then place your braces in the correct locations and use the go-bar sticks to apply pressure for gluing. Please check back in the near future for detailed pictures on the use of this product. We will also have video clips on how to use it. For care and maintenance we suggest that you keep it clamped to a table when not in use, or glue to heavy backing material to be sure it does not warp over time.

How to Use This Product

The radius dishes with sandpaper are also used for glueing the top and back braces on to the top or back using a go-bar deck. With the addition of sandpaper, you are able to sand the bottom of your braces to the exact radius of the top or back. You can also sand the sides of the guitar with the lined kerfing installed to get the exact radius of the top or back. This produces a much less stressful joint as the sides will accept the top or back much more easily because it will have the same radius as the top or back.

For radiusing the braces, just place the brace on top of the dish, then use a pencil to roll it on the bottom of the dish while at the same time drawing a line across the bottom of your brace. You then use a hand plane to plane down to the line, then use the dish to finish it off. They should fit in the bottom of the dish with slight downward hand pressure.

These dishes can be used to radius the sides to the exact radius of the top or back. Make sure you use the correct radius for the top of the sides to match the radius of the top, and the correct radius when sanding the back/bottom of the sides for the back.

These dishes can also be used for glueing the top or back in a go-bar deck. You just need to place 3 sheets of newspaper down on top of them to protect the top or back from getting scratches. Please check back in the near future for detailed pictures on the use of this product. We will also have video clips on how to use it.

Ukulele Dish

 

1 EXTIRA MDF Ukulele Sized Radius Dishes(Does not come with Sandpaper)
We now offer Radius dishes for Ukulele building. Because most Ukuleles have a radiused back and flat top, we only offer one dish. Use these dishes to radius your rims and back braces, and glueing your top/backs on in the correct radius dish. These dishes will work with Ukulele sizes of Soprano, Concert, and Tenor. They do not come with sandpaper because they are so small and it is hard to find the correct sized piece of sandpaper. The 3M Gold Stickit sandpaper will work great on this dish. This dish is made with the highest quality waterproof EXTIRA MDF available. They are 12" wide by 16" long and .80" thick. These come in any radii of 15' or greater. For a radius less than 15', please add $20 per dish.
