Holding down smaller pieces
Up until now, every piece I've carved, I've been able to hold down with clamps. A friend asked me to carve some lettering on the top of a ring case he is making. The piece is approx. 3/4" thick and 4 1/2" in diameter. The material is Oak.
I've thought of 2 sided carpet tape or some type of glue. Does anyone have any good suggestions? I don't want to screw this up.
On a side note, does anyone recognize the font?

Re: Holding down smaller pieces
I assume that you put masking tape on your spoilerboard and the underside of the piece to be carved and super glue between them. Is regular blue masking tape OK?
Thanks Randall, for the font.

Re: Holding down smaller pieces
I use CA glue and blue painters tape. It took some time for me to try it because I just didn't think it could possibly work, but it does...
I also like it better than edge claps because it holds down the material over the entire bottom surface and not just around the edges.

Re: Holding down smaller pieces
Carpet works fine, just not if you're doing through cuts. Then it gums up your bit and makes a mess. Also, the CA glue and masking tape doesn't work if you're using a HDPE spoilboard like me lol.potzmannwoodshop wrote:redwood wrote:2 sided carpet tape

Why would you use such an expensive material for a consumable material?

Why do you recommend not using 2 sided tape? I have used it before with no problems.potzmannwoodshop wrote:redwood wrote:2 sided carpet tape

Re: Holding down smaller pieces
Well, it is not entirely HDPE. I have a sheet of 1/4" aluminum as the base, with strips of 1/4" HDPE as the spoilboard material stuck to it using....... carpet tape.potzmannwoodshop wrote:Mobius wrote:using a HDPE spoilboard like me lol.

We were using MDF, but it is just such a.... unpleasant material. We'd surface it, and come back the next day and have to surface it again because the humidity changed.
And then we started doing a lot of aluminum cutting, which required some coolant mist. Which absolutely ruins MDF.
So far the HDPE has been great. As long as the temperature remains constant, we rarely have to resurface unless it gets chewed up. And we rarely cut into the spoilboard (other than user error), as it remains consistent enough that we can zero off of the table instead of the stock. Biggest downside is that it can be slippery, so double checking the hold-downs is key. That and normal painter's tape won't stick to it, so no CA trick.

Re: Holding down smaller pieces
Darn. After thousands hours of successful machining with this method, I discover I shouldn't have used double sided tape.potzmannwoodshop wrote:Super glue and masking tape, look it up online for the method, dont ever use 2 sided tape
When you are using masking tape or blue tape and super glue, what are you doing but making your own double sided tape?
I agree than carpet tape is generally not a good solution and that finding the good double sided tape is not that easy. It must hold down firmly the material and be easy to remove. The one I found looks more or less like a carpet tape, but the fabric base is more loose and it seems less gummy then carpet tape. Unfortunately, is is not branded, so I can't be of more help.
Double-sided tape is not always a good solution for wood. Works fine on some hard woods. Despite a strong holding, it can be insufficient if wood twists while cutting.

Re: Holding down smaller pieces
I would use 2 clamps on the side areas. There should be plenty of room on the sides.

Re: Holding down smaller pieces
Another choice would be to screw a piece plywood to the underside of the wood. Place the screws strategically to avoid being hit by the bit, then attach the plywood to the spoil board.

Re: Holding down smaller pieces
I hold down 3/4" wood all the time and use Shop Fox clamps. Sometimes have to get creative with some odd shaped pieces but haven't had any issues...yet.

Re: Holding down smaller pieces
You could use hot glue on the bottom and hot glue blocks around it to prevent movement. Then use denatured alcohol to release the hot glue when done.
