Array of small holes
Posted by Don Stauffer on Thursday, November 28, 2013 9:52 AM

Going to be starting a Link Trainer model soon.  One problem I foresee is that the base unit is a box, with each side having two hundred tiny holes (in 1:24 scale they will be about thirty mil on about forty mil centers.  That is a total of 800 holes!  I can't see drilling that many!  I have made other arrays by laying out the holes in CAD and making black spots for an inkjet decal.  But the base is black, so I don't think that will work well here.  Seems to me I remember a K&S PE grating at the LHS.  Don't remember hole size or spacing, though. I will be going to LHS tomorrow, but anyone got an idea if that doesn't work out?  The holes are in two arrays on each side, a square array of one hundred in each lower corner.

Don, I wonder if the carbon fiber simulated decals, that auto modelers use, would be helpful here?

Other than that, do an image search on metal screens and you might find a graphic to create your own decals from.

If you are looking for something more 3D, I think some of the PE brands, like Eduard, do make a generic mesh, but is the pattern and scale fine enough?

This site has a circle mesh pattern, not sure if size fits your requirement:

Hello Don!

Recently I had a similar problem - I wanted to make 16 road wheels each with 6 1mm holes, close to the border. I made a CAD drawing and took it to a nearby company that had a laser cutter. They needed like 15 minutes to do it - so I guess you can find a similar company in your area and let them do the holes for you? Good luck with your project, have a nice day

That PE item looks like it might work.

I have been looking for a local company that will do laser cutting.  That would be a good application- I'll look harder.

What material will you be using for the base?

I will be using wood, but probably sheathed in thin styrene sheet for ease painting and four detaling such as the cooling holes and latches.  I am contemplating using brass or copper for the sheathing, however, and trying to etch the holes. I do have the Micro Mark etching kit, but the full-blown photo etching process is a LOT of work.  I have had some success with toner-transfer etching, but it is limited in the fineness of detail, and I doubt its ability to make 030 holes. I'll give it a try, though.  There are a couple of other parts with coarser detail that lend themselves well to etching, so I guess I'll try one of the base sides with the cooling holes in the layout for the etching resist pattern.

I was at LHS yesterday, and asked one of our club members who works at the store about the K&S etched gratings- he said they were discontinued and none to be had anymore.

Yes, a pic would be nice, and particularly give me the brand from the label, and any stock number or other info.
