…...................…………........--- High Bridge Part 3 ---

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

Continuing on with getting what I call the ‘High Bridge’ designed, printed and put in place along with the foam work in the area. I had worked on this some back in November of ‘23 (High Bridge Part 1) and done a little more work on preparation for it in December of ‘23 (High Bridge Part 2). Now hoping over the next week or two to have it maybe 90% finished…....

I have cereal every morning and save the boxes (not all of them) as they make for great patterns. The top of the pattern is the end view of the bridge section shown that the upright supports will attach to.

The far one above is a single upright to the end of the first span and will sit next to a road there and a bridge that spans the tracks in front of the tunnel (print files are up for it).

The next one’s main members go all the way to the ground in the same area. The one on the left is more complicated as …..

….. two members will go all the way to the ground but the other two will be further up the hill. I decided to stop foam at this level and move to the computer to design the uprights with the hope of then putting the foam in to pretty much work with them.

Before starting the CAD work I thought I should get the trestle in place temporarily. I taped the walkways as the grating there is really fine and didn’t want to clog it with any more paint than necessary.

I hadn’t painted with the air brush for probably about a year and not much with it before but do have experience with a large gun. I paint a lot with a brush and forgot how easy and fast it is to use the gun vs. the brush for painting something like the interior of these bridge members. Also you don’t loose as much detail buried under paint.

I researched guns quite a bit before buying the iwata and haven’t been disappointed at all in spending the money on it. I also bought a nice gun (good reviews) on Amazon for around $50 and was going to use it when possible. I don’t use it much at all as this gun is so easy to spray with.

I was using the black ModelFlex to the right but was going to run out so thought I’d give the cheap DecoArt acrylic a try. Put some in small cup, added some water to thin it a bit and it sprayed as well as the ModelFlex. I use the DecoArt with a brush as it is cheap and I can get it at the local hardware store. I’ll try more in the gun also now after using it here.

I made the paint booth above a while back ( HERE ). Used a duct fan I already had and it works great. Filters are ones I can buy at the local Ace Hardware. I have a long plywood panel that the hose goes through that I can stick under the garage door to the right. With the acrylic and all the air in the shop I hardly use it like that. The hose gets what little fumes there are away from me far enough I don’t even smell them.

.

Went back to my non-air-brush to add a little weathering.

I put the bridge/trestle up on the abutments to see how it looked and was surprised at how strong it is. After the picture I did put in a piece of foam for support in the middle while I work on getting the supports designed and in.

Now on to a lot of CAD work…....
