View Full Version : Recent Projects (or how to not paint cedar)

Thought I would post a few pictures of things I've been working on recently. I made up a set of Route 66 patterns for (kind of big in this area :) ), took some searching to find the authentic font (had to buy it), most of the memorabilia sold today actually uses the incorrect font. The letters have a slight dome to the top and the whole pattern has a slight draft. I was astounded by the results of the added draft. My test carving was done in MDF about .25" deep, 9.5" across. There was no chip-out on the lettering even though it was only about 1/10" thick. The finished one was done in cedar and is about 12" square. I tried to do the white as semi-translucent (after sealing it with clear cedar sealant) and it looked horrible (my wife was wondering why I was covering up all the beautiful wood :p ). So I spray painted it white with black lettering. From now on I will only paint the lettering the rest will stay natural. The patterns are here (http://allcw.com/JeffBirt-MiscPatterns.html) if anyone is interested (one for each state the 66 ran through and one generic 'Route 66')

The other sign was also carved in cedar. I actually designed it several months ago but never carved it. It was all done in Designer so I was not able to add a draft to it and got some chip out on the letters. I just included it as a reference of how well cedar carves. I sealed it with clear and will do a bit more clean up with 3M bristle discs before painting the lettering. I am hoping that sealing it first will make the surface a bit harder and easier to clean up with the bristle discs without doing damage.

The other item is a 3 layer petal box shaped like a forget-me-not. The layers of the box pivot open. I tried to an irresdescent look to the paint which came out so-so. My daughter is wanting to redecorate her bedroom in a flower motive, so I thought this would fit right in. The pattern and project are available here (http://allcw.com/Projects.html).

Jeff,

Your signs look really great. http://www.carvewright.com/forum/images/smilies/icon_biggrin.gif

But I have to ask and reveal my ignorance. -- quote -I was astounded by the results of the added draft.

Draft used in this context eludes me, hmmmm Let me see
I remember being drafted
A current of air in a closed-in space
And enjoy a draft beer now and then
The use of drafting behind a race car the save fuel
A bank draft
I've heard of draft horses too
The depth of water a ship draws
Even did some drafting some years back.

Draft you got me ? http://www.carvewright.com/forum/images/icons/icon11.gif -- angle, taper; specifically : the taper given to a pattern
Did I come up with the right one?

Jeff, How did you get the machine to cut a draft ? In the foundry draft is the dgree of angle on a pattern to allow it to release from the sand. I have to make { or have made } 3 press no. plates , If i can make them instead of paying a pattern maker $1000.00 each i am all over that one. Thanks Michael

Yep, you got it :)

The pattern was created in ArtCAM ( I have limited access to it ). It has a neat feature that allows you to create a draft on the whole relief. It's really a great program, just more $$ than I can afford.

Al, sleep is for whimps;)

You could also create draft on a project by outlining pattern and using the tapered carving bit , right? A nd also cutting the project from the wood with the tapered carving bit.

Is this right ,or am I missing something here?

The carving bit does have a taper so everything you carve will have at least that same taper (draft). The problem is that as you carve deeper and deeper the whole bit is still contacting the wood and as you pass an sharp edge, like a letter, all that contact between the bit and wood causes chip-out. If you can design the piece with just a bit more draft then only the portion of the bit that is cutting new material is in contact with the stock and your chance of chip-out is greatly reduced.

One thing I have done is after the carving I had it outline the pattern ,which routs around the letters with the same carving bit cleaning up the letters from what the carving bit leaves.

Just thought I would post a photo of the finished cedar sign. It was just done to test working with cedar. I have found that cedar carves and paints well.

The sign was carved, quickly sanded with a 3M bristle disc (if you don't have bristle discs you need them), sealed with a Cabot clear cedar siding sealer and then painted with latex paint. The finish technique was recommended by http://www.wrcla.org/pdf/WRCLA_Guide_to_Finishing.pdf

Jeff,

The Custom Wooden Signs looks great, and the Finishing.pdf
is a good source of info on staining or painting the Western Cedar
I've just started using some. It's a pleasure to work with.

Thanks for Sharing
