…..............................--- Sawmill Design/Build – Part 12 ---

=========================================

If you have a sawmill and a mill pond you probably need a boom boat to sort and move the logs to the log lift that will start them on their journey into the mill. If the boat is broke down or the mill doesn't have one then men have to get on the logs with long poles and push them where they need to go (the boat is faster and easier).

Above is one of the boats I've seen in action in videos of Hull-Oakes' boom boat in action. Lots of really good videos of Hull-Oakes' boom boat in action and also the mill in operation ( HERE ) down the menu a fair ways (9 years ago as I write this).

Of note is the fact that these boats look like they are about to sink since they sit so low in the water. They are designed like that and it is amazing how maneuverable they are (check out the videos above).

I didn't need to design the boat as deep as I have but did so for a couple reasons. I'll probably add another print option with some of the detail that is shown below the bottom of the boat in the bottom left corner of the image above. I'd put that boat up on stands in the scene and it is being worked on. I'll probably have another tied to the dock at the debarker building and maybe a third in action pushing a log and heeled over like what is shown above down at the lower right. For the boats in the water I'll dig the foam out and set them down into the water either straight up or heeled over.

After about 5 hours of design work with Fusion I had the above finished. The cab was fairly usable but the rest of the boat wasn't right the more I looked at images of the boat shown in the images further above. With no measurements to work of it was a lot of looking a the photos and guessing what they probably are.

Two more days got me to where I'm 90% happy with the boat above and ….

….. the same boat but with a cab for more weather protection. I moved the files into Chitubox and let it add the supports. Normally I'd tilt the object and looked at that but more or less flat worked out really well with the stock supports Chitubox add.

There is some really small detail on the boat that I didn't know how well it would print and/or if some of it would break off removing the supports so printed three of each version.

They all printed great and I'm continually impressed with how versatile the Siraya Tech 'Build' Sonic Grey resin is both in detail, strength and not real brittle.

I keep reading about all the new printers and what great detail they can print but what this $200 printer and resin can do I'd only probably buy one if I wanted a larger build area. This one with a little over 6 inch build plate has done about all I need. Still use the Ender 3 Pro filament printer for a lot of larger prints.

This boat isn't very big as shown by the measurements above.

The steering wheel is about a scale 16 inches in diameter. The two parts of the post cleat at the stern that project out from it are a scale 3 inches in diameter (.020”/.5 mm) and printed and didn't break off. There is some detail on surfaces shown that is down to 1 N scale inch (.006”/.15 mm) that prints but I don't think would print up in free air like the parts of the post cleat.

.

I have about 4 small additions/changes I want to make and then I'll post the print files up on my thingiverse.com account and the links to there here when I do.
