Hello everyone,

Aside from the *Grainfraim*, does anyone know of *other* methods of creating a woodgrain look in HDU.

A couple of local shops this way do it with excellent results and here's what I know about the process: (Add to it what you will...)

1- Sandblast a *general* flat background about 1/4" to 3/8" deep.

2- Change nozzle to a smaller orafice and reduce CFM (so as not to blow thru the HDU), cutting ( up close) random horizontal lines into the existing background.

Here are a couple of examples, but I/we welcome elaboration on the technique by those who may know better, especially by those who have methods for routing wood grain akin to the pictures you see here too (maybe even a combo method SB and routing:

Note: the grain is *beafier or chunkier* which allows for good visibility of the *effect* from a distance.

Hope I did that right, if not go to:

Thanks,

I like the signs. The grain is a nice effect and it looks easy to paint.

The freehand blasting looks good to me. I bet you have to concentrate on uniformity. Just don't sneeze while blasting [Wink]

I have done similar things by hand with chisels or a dremel tool with a sander drum. Your method looks like a winner to me.

I thought from what I saw of the grain fraim that it was too sterile/uniform, and also quite expensive.

We made our own and feel that the surface looks abit more alive, so much today looks so "perfect".

Nice work though always interesting to see how others achieve a good finish

Thanks for the responses thusfar, however, I was looking for more input about the method described.

Henry, I thought your grain was more wood realistic, but chunky...no offense, it looks good.

I like the regular pattern of the examples I provide but need to know more about the method if anyone has more specific info. My (described) method is about the fastest....no grain fraim, no chisels, dremels, etc. Two blasts and wahla!
