Packing Tape

[Rockytime]

Today I covered a blank with painters tape, applied the pattern with spray adhesive and covered the pattern with packing tape. This happened. Why and how?

[trackman]

Looks like the tape didn't stick to the pattern. Did you smooth the tape with hand or some other type of rower?

[Rockytime]

I burnished it down with another small piece of wood. That also made sure the pattern was firmly secured to the wood. I can use it OK but it is irritating when I start a cut.

You really do not need the packing tape. The blue tape will do what the packing tape will do. Every roll of tape has an coating on top so that each layer is easily pulled off and that is the basic reason the theory of packing tape came about. It is the coating on the tape that is suppose to lubricate the blade. I do not believe anyone has really proved or disproved this but  it is what it is. When I first started I used packing tape and have since gone away from it all together. I do use colored painters tape under the pattern. Blue if I am going to peel away in a day or two. Purple or green if I am leaving on longer. The latter two have less tack. We all know the longer we leave tape on a wood it will be harder and harder to get off.

I'm thinking Les when withdrawing the drill bit adhesive from the packing tape and painters tape is adhering to the bit. My suggestion would be to lightly rub bit with wax such as a bees wax or try a finer bit.

[dgman]

You don't need both. Use one or the other. But it really looks like your drill bit is dull and maybe not fast enough.

[Lucky2]

I agree, dull drill bit, and slow speed is more than likely your problem. When you drill the hole, do you just drill the hole, or, do you pump the drill bit up and down a couple of times to clean the hole out?

Thanks for the ideas. I do believe the packing tape was a bit much. The drill bit is sharp but I like the idea of putting a little wax on it to lubricate it. It only did this when I used the packing tape. This was a first time. I usually only use the blue painters tape.

The very reason I stayed away from the packing tape after the first time i tried it. No tape at all.. I can see no reason to use it any longer.

a quick vibrating saner should clean it up for you.i do this sometimes when it looks like yours .I've noticed high speed drilling does a nice clean cut job

Karl Taylor addressed this, He used a credit card or like to smooth it out. I haven't tried this but sounds like you get a better bond in the substrates.

To much tape as said before only one layer required I use re-positional spray glue on wood place pattern and two inch sellotape works perfect every time. Roly

Looks like you have your answers above.  I'm anxious to see you cutting when you complete it.

I used to use just the packing tape but I was getting a glare from the lights that made it difficult to see the line I was cutting. I just use the blue tape on all projects except portrait style with lots of small fine cuts. I just spray the back of the pattern and apply to the bb ply and use mineral sprits to remove the pattern. When I was using packing tape I had the problem with the sawdust getting under the tape while cutting and making it even worse to follow the line.

I have stopped using packing tape. More work than necessary to clean it up and not sure of the lubrication benefit. I have printed patterns on photo paper in the past but it is expensive and it can smudge . I have also used a thicker card stock paper that works great. After drilling the holes, I will either hand sand the back or touch it on my (cheap HF) belt sander to smooth the back. You may also want to consider trying a brad point drill bit for larger holes. It leaves a much cleaner hole. I have also invested in a good hard wood wallpaper seam roller. It takes out all the wrinkles or bubbles that can trap saw dust under the pattern and lifting of edges or corners on very small cutouts.

[JustLarry]

That is the reason I stopped using packing tape.  To much time to get it down right and the time to stick it down good cuts into my cutting time.  Just painter's tape or no tape at all.

I dont use either one.

 

i use a super thin coat of spray glue, super thin so its basically hardly attached.

 

i do super fine work as well with tons of tiny pieces and thin lines and never have an issue.  The pattern doesnt need to be on there for life.  just long enough to cut the piece.

 

less is more sometimes.
