Did some experimenting this afternoon. I always suggest. like many others, to use tape to help with eliminating burnig. The reason for that is, that the tape has a chemical on top, like a silicone to release friction.
I found a can of silicone in the shop and started to cut in 3/4" Oak till it started to burn the wood. I clued a piece of paper on the wood and sprayed a light coat of silicone on the paper.
The burning stopped. It also seemed that the paper came off a lot easier but that can have some to do how much glue was used.
I would like to hear from others if they would have the same experience and let me and others know.
Would make it a lot easier than to use tape.

I personally would be afraid the silicone would leach into the wood and cause problems with the finishing process but it could be open to experimentation.

I have been woodworking for twenty years and have been told many, many times to never use silicone spray in a wood shop as the silicone will interfere with some finishes. I have seen pictures of what it will do, so I never use spray silicone in my shop! I prefer to use clear packing tape on top of the pattern. If it is thicker wood like 3/4" Oak or maple, I will also apply clear packing tape to the bottom. If I do that, I will apply a blank sheet of paper first then the clear tape. The tape and the pattern will come off easily with a heat gun or a spray of mineral spirits. Using this method, I never have any burning.
A lot of folks use blue painters tape on top of the wood instead of the clear tape on the pattern. I have a hard time removing the remnants of the blue tape around very small cut outs, so I prefer not to use it.

GB,
There was nothing on the wood. The glue might have prefended that.
Dogman, I never heard of that before. Used slicone for a long time in the shop and never had a problem with the finish.
I posted the tread just to find out if others would try it.

i would say it depends on the type of silicone that is used, but a interesting subject

I used a very, very light spray.
Next time I will use a small paper towel, spray it and than wipe it on the pattern.

I also have been told that silicone can cause orange peel and fish-eye problems with a lot of clear finishes. Many won't even use it on table saw tops and fences for rust prevention for the same reason.

Hi guys, Go in to a paint shop with a can of silicon you will get lynched immediately. It is carried all over the place by the slightest airflow. I've still got the bruises on my butt to prove it and that was a number of years ago LOL.

Why go in a paint shop and start spraying around.
Never heard about that. ;D Does not make sence.
FD Mike

I would also never use silicon oil with the wood - also I'm using some kind of to lube here and there (e.g. the blade clamps) once in a while.
-
I did not know that silicone was an oil.
Are you sure Thorsten?
FD Mike
-
the silicon spray? I don't know exactly, but I'm pretty sure that it's a silicon oil (http://en.wikipedia.org/wiki/Silicone_oil) in the spray can.
-
Thorsten,
You better check with a company who makes it before suggesting some what you are not sure about.

In some oils they put silicon.
Simple example, the oil of your car.
It's because of the silicon in the oil that you need to change oil after a lot of miles (kilometers) instead of every 10000 miles as it was about 25 years ago.
So why shouldn't they put silicon in other oils?
-
Let us forget about oil.
Just try it and you will find out how nice it works.
This afternoon, I put it on a paper towel and wiped it on the pattern. Put glue on the back and put it on oak. No sign of anything after I removed the pattern.
It is the way for me from now on.

In my summer job I work with plastics and we use a silicone based mold release spray on several of the molds we use. The silicone transfers from the mold to the part in the vacuum forming process and sticks through the cutting and trimming processes and can mess with the sonic welding done later. It is tough to remove from plastic, and a bear to get off of hands. (Don't even get me started about what it does to my clothes)
I have heard the warning about not mixing silicone and wood, but I am interested to see if your process has any contamination issues.
-
Like I said yesterday. Put some on a paper towel and got some of my hands. Did not have a problem at all. Did not even know that it was on my hands.
I worked great. Try it once Dogman and tell us how it works for you.

Like I said Mike, I know better than to use silione spray or waxes that contain silicone. once it gets on saw tables it will remain and contaminate your workpiece. This will cause problems with finishes. Have you put on a finish on your projects that you are using the silicone yet? Tell us what happens when you do!

This is what I use:
http://www.simsupply.com/p-61204-7-12oz-hv-duty-silicone.aspx?CAWELAID=1303391886.
This what I found:
"CRC" HEAVY DUTY SILICONE MULTI-USELUBRICANT *7.5 oz net *Lubricates and protects most metal and non metal surfaces *Dry film eliminates binding and sticking *Colorless, odorless, non staining *VOC compliant *Can *Discovery CON, NBR, SUP
"CRC" HEAVY DUTY SILICONE
Dogman, are you talking about the same product?

I can't say what effect silicone has on wood, but I can testify to what it can do in a shop.
When the guys in our shop were using silicone instead of Top-cote on the table saw and other tables, there were times when the floor around these places were like ice! Very dangerous! They have since gone back to Top-cote.

Hi Karl,
There is no way to spray a very light code on the pattern; than spraying a big amount on tables. There is no way you can get anything on the floor.
Why so negative, Try it and if it does not work for you, so be it.
FD Mike
-
I'm sorry Mike you feel I am being negative. As I stated I cannot say what effect silicone has on wood.
What I said regarding how dangerous silicone can be on a woodworking shop floor is fact! I have seen it and felt it.
I would encourage any new technique, but I also encourage people to pay attention to advise given by knowledgeable and professional people of which many have posted above.
I'm glad it works and I think I'll try it when I get the silicone from work this week.
Thanks for the tip.
Karl

I am sorry Karl,
However you need very little silicone on the pattern. A very small mist is enough.

Thorsten,

FD Mike
I guess they are a bit picky on telling anyone what's inside - don't ya think?
But I know that fluid silicone is very thin. To get it sprayed with a can one needs a certain consistency of the fluid - so I guess they don't use it pure. Would also be too expensive.
-
Thorsten,
I was not talking about liquid silicone. It is a spray.
Wonder how all the companies making tape; put it on the tape, so that you can un-roll the tape.
I love to hear from folks who tried it.

Mike. I use silicone spray on my tables, saws, joiner, planer, ect, and I never had a prob. Maybe where I'm using a oil base stain too why it dont show up. LOL!.
-
Just to fan the flames a bit here. I use silicone spray to lube and prevent rust on my saw table, after spraying it on I let it set a minute then polish it dry with paper towels. So far no problems with the finishes on my projects. I normally cover both sides with blue tape anyway because I have a hell of a time getting clear packing tape off. I do use the clear tape over the pattern and spray adhesive on the blue tape to attach the pattern. Works for me!
Sign me slippery table Gabby ;D
