Mike. this is the first project I have taken on and have only done a little wood work with my father as a boy.
To make the interior I measured up the interior of the Boler
, sketched up what I wanted, then purchased the wood. Almost everything was build on a table saw, it cuts straight so I do not have to. The cupboard doors where made by coping a youtube video.
I built it in the trailer to fit (always checking to make sure it would still fit out the door). I used cardboard to get the curves, then transfer jig saw. I then sanded it to fit perfect. I quickly learned doing it right is the easiest way, but sand paper can fix a lot.
For filler if needed I used wood glue mixed with saw dust and to finish I used bondo if needed.
To stain I jest read the stain can and followed the directions. Sanded well, use a wood treatment, then stain, then a few layers of the clear finish. Once done I sanded it with a 2000 grit from the body work section of a store.
I glued and screwed everything together. I found the hardest part of any new challenge with this project is starting, a few dumb questions at the hardware store and lots of internet searches got me here.
I would make sure you have a good table saw, mine was too small, making things more challenging. I would also get a good sander, as you will be using it a lot. I also found a small rotary tool did anything I didn't have a tool for and quickly shaped the wood when needed.
The design, measurements are all detailed I think earlier in this post and for sure on my blog, ourboler.com.
For wood I used pine boards, 15" by 96" and pine plywood. If I was to do it again I would use more of the full pine boards.
Any questions let me know, I have asked my share to get this project this far
Good luck with your trailer!
