............................--- Roundhouse Roof Supports ---
There are a couple different options for the roof supports. One is posts with no bases and the other has what appears as concrete or stone bases.
The length of the post/beam support assembly is a little short to ease in the assembly in case things are off a little. I'll leave it up to you to fill in the end gap if that becomes a problem for you.
You probably will want a post/beam assembly on the sides of each bay but might want to leave out the first one on both ends by the half bay that is at the end walls. I'll probably put them in there also.
If you print posts without bases and want to add them you can print out a sheet of 12 and use those. I use about a .039 drill bit to drill out the corner of each one and then an Exacto knife to cut the rest out and clean the hole up with the knife. This isn't too difficult if you leave them attached to the bottom sheet piece while doing that.
If you use a different thickness floor than what I've designed you have the option to print the post/beam assemblies with different length posts. If you do that and want bases you are going to have to print the bases separately and add them to the posts.
If you end up with the three floor thicknesses of .040, 060 and .060 ( .160” ) or any other combination that ends up .160” thick you can print out post/beam assemblies with most of the base printed with the post. You will end up with posts that have the base on three sides. They will also have a cross-beam support up at the top of the post for cross-beams. I don't have print files for the cross-beams. I'll probably use scale timbers for that (16” x 24”).
There is a print file for the cross-beam supports that can be printed separately for use on the other side of the post or for prints where the posts don't have any cross-beam supports.
.
You can print the partial post bottoms above to glue to the bottom of the posts that don't have them printed on one side.
There are a couple different options for different length posts if you go with different floor thicknesses than what I am using. If you don't find the right length shim one or cut a post to the right length for your situation.
.
16 post/beam assemblies for the roundhouse which will have 15 bays. I've got about 2/3's of the prints done. Depending on how many bays you are going to have there can be a lot of printing. Once you have the end walls printed and the four corners printed count on an additional couple hours of printing at least for each bay (back wall, front wall and roof detail).
This about concludes the files for the roundhouse. I am working on a higher roof section that could be used over two adjoining bays. The purpose would be to give addition height to the inner roof over a loco for a gantry type crane. The crane could move back and forth over a loco to lift heavy parts of the loco used in repairs. If I like it I'll add it at a later date.
You can find the print files for these roof supports ( HERE ).

NOTE: This concludes the files for now (01-25-21). I'll probably work next on roof supports.
