Cutting 1/4" round masks out of Tamiya tape ?
Posted by Wilbur Wright on Thursday, March 1, 2018 8:59 AM

Does anyone know a way to cut round masks from the larger Tamiya yellow masking tape? 

 

I am dullcoating the 1/35th Italeri MTB 74 and need to mask portholes that are about 1/4" inch in diameter.   I need to cut about 20 of them.

I've already used up all my excess leftover Eduard round tire/wheel masks.

 

Thanks for any ideas.

I usually reach for my punch and die set to kick out round masks. The Waldron set falls short of 1/4", so I use a set designed for leather work - around $5 at the art supply store.

Yes, put the tape on a thin sheet of plastic. After you've punched the disks, peel the tape off the little plastic disks. They come in handy so keep them.

 In fact, I just noticed in the photo that I used them for the refuel covers. One's visible in the background.

You can use a simple circle template found at most craft stores in the drafting section.  Use a new blade and be sure to cut on glass.  A cutting mat does not work to keep the blade tight up against the edge of the template.

I do this all the time and can cut perfect circles down to 1/8 dia before I have to move to a punch set.

I've used the round templates but I've had problems cutting the template with my knife. One thing that I have done is to put tamiya tape on a metal plate. (mine is a back of a outlet box) I pick a circle size just slightly larger than what I want and I use a fine ballpoint pen and go round and around several times.  This seems to cut a nice circle and it worked well for masking tire hubs for me.  Funny thing is that I've tried pens that are out of ink but they don't seem to work

Another thing you can use for a backing is the backing sheet that address labels come on.  I usually get a ton of those address labels around x-mas time.

That’s a good idea.

Off the original question, I’ve done the same with white glue.

Tease a dot on. It usually can be popped off with a needle.
