Still Not Getting the Results I Want From the Cricut

When I bought the Cricut and Sure Cuts a Lot, I was hoping that I'd be able to do work similar to what I'd seen in laser-cut model railroad building kits. My best hope was that I'd be able to cut out a full structure kit out of thin basswood and cardboard. My narrower hopes were to be able to make some of the detailed bits that cut really well in laser-cutting - really fine HO scale windows (with each sash cut out of thin 0.020 cardboard) and strips of cardboard notched to resemble shingles with double-stick tape on the back for adhesion.

The Art Deco building for Campbell showed I could cut a full building, but most of the success there was in cutting the big wall pieces. These aren't particularly hard by hand; it can require a lot of tedious measuring, but cutting out large pieces is pretty easy. I did make the large storefront window from multiple Cricut-cut pieces, and so does count as a success for the cutter. However, I used commercial plastic window castings for the more traditional door and window.

I've tried to make double-hung windows as nice as the laser-cut kits, but the Cricut can't cut them nicely even after I've massaged the SVG line drawings to cut better. I can get paper to cut cleanly with 0.050 inches between cuts, but the 0.020 inch boundaries at sash lines usually tear even with good Strathmore board cardboard. I also still have problems keeping the openings both square and fully cut through. Cutting the entire window opening in a single cut means that the waste piece usually falls out easily, but the corners aren't always square. If I cut the window openings with multiple straight line cuts (cut in both directions), the Cricut still has problems fully cutting through.

Today, I decided to try making shingles. If you haven't seen laser-cut shingles, the shingles are 1/10" wide strips with thin notches cut along one end. To apply these, you glue them to a roof surface, overlapping each row, and with the notches exposed. It makes a neat, realistic roof.

I'd been able to cut small batches of 5" long strips of shingles, but this time I tried to cut a full 6x12 inch sheet of brown construction paper into shingles. I found the cutter does really bad if I'm constantly cutting along the 11" direction because moving the whole carrier sheet back and forth eventually causes the carrier sheet/cutting mat to skew, throw off the cuts, and jam the cutter. I tried reordering the cuts so I did a row of narrow slits across the paper, then moved the paper a bit and cut the next row, and finally cut all the shingles off in one step. I found that even with small movements of the carrier sheet, I still ended up with a 1/16" error from one end of the sheet to the other. Maybe there's some ways to arrange the cuts to avoid the error.

There might be manual workarounds; while cutting all the individual notches for shingles would drive me crazy, cutting the long strips would be a few minutes work with a straightedge. Maybe I could do the slits with the Cricut, and then cut each row of shingles off by hand with a straightedge, or try to cut smaller batches so that there was less chance of accumulating error between cutting the slits and cutting the strips of shingles out. I wouldn't want to do that if I was making shingles to sell, but it'll be easier for the small amounts I need for personal use.

Ugh. I see promise with the Cricut. Watching it cut the slits for the shingles was a nice reminder of the fun of automation - the Circut was cutting several hundred little slits pretty precisely, and doing it all over twenty minutes while I could sit outside and enjoy some nice weather. Unfortunately, I don't feel like I can actually make anything at the level of accuracy for the models. It could do great at curved shapes,so if I wanted to model Gaudi's Casa Badillo in Barcelona (picture borrowed from here, I'd be doing great.

Sigh. Maybe I do just need to bite the bullet and start spending time up at TechShop borrowing time on their laser cutter.
