Progress thus far looks great!

I am watching with interest. Love The Glen, and I always like watching scale models of real tracks being built.
Great job so far. Don't be afraid of mistakes, bondo fixes anything. ;)

I hope your right, I feel I'm going to need plenty. Any thoughts/recommendations between using Bondo or Durham's Rock Putty for repairs?

Personal preference really. I still like Bondo if it's feasible. It dries in minutes and you can sand it away. It also sands easier in my opinion. The only real drawback is the smell. If your track is in the house, it's going to make it smell like a body shop. Durhams has no odor at all. But you have to mix it with water and it takes a lot longer to dry. And just like the name implies, it's rock hard.

Durham's for simplicity, cost, VOC, smell, and though it takes longer to dry; once it dries it is solid. Bondo dries, but then there is (for want of a better term) a curing period before it is 'workable'.

Have used both, over the years in cabinet and display construction; but Durham's gets my vote.

P.S. LOVE your project and the way you are going about it. As has been said, The Glen RULES!

Yup, what Dave said.
I do my routing outside, so I prefer bondo for the speed of rework. However Durhams is absolutely rock hard when dried and I have repaired router wobbles with both materials.

Most tracks have some things like that but they disappear when the surface track is painted and finished.

I found a problem in my Excel worksheet used to calculate the scaled down turn radius from the original track survey. Had to recut some of the MDF and then Summer projects and life got in the way of track progress. I'm finally ready to start routing the lanes after re-locating some of the racing lines this week. Will be posting some new pictures soon.

Finally back to working on the track after a long delay. I had to re-cut some of the MDF after finding an error in the Excel worksheet used to scale down the actual turn radius and dimensions from the original track survey. This problem affected all compound radius turns. Before starting again I wanted to make sure the inner and outer lanes would have enough pavement through the racing lines which was a problem during the first attempt. I located the desired racing line, which is always a compromise trying to fit 3 lanes into the track width. I had already decided not to use squeeze sections which would have helped but I opted not to use them. Using the flexible fence and a round pencil turned down to fit in the router collet I marked all lanes before routing. This allowed me to see the location of all 3 lanes and make any adjustments before routing.

Adjusting locations

Once I was satisfied with the slot locations I had to reposition some of the joint screws

Setting up the flexible fence on the outer lane position so I can rout the center lane slot. This slot will be used to rout the outer and inner lanes using a 1/8" flexible fence in the center slot.

The dust port on the router which is attached to my shop vacuum does a good job of keeping the MDF dust to a minimum.

I will continuing routing the center slot around the entire track 8 feet at a time (length of the flexible fence) then go back and rout the inner and outer slots.

Could you please share a picture of how you did the joints from underneath
Thank you

Here are some pics of the joint. I used a template and spring loaded center punch to locate the holes for drilling. The extra holes in center is to allow offsetting the screws when trying to anticipate were the center lane slot would be located.

This a picture from underneath the joint. It's just some scrap MDF cut a little shorter then the track width, I used fender washers and nuts to secure the joint.

Really nice work. I love the detail on the table.

Mine? I figure I'll be tearing it up in a few years again when I move, so I'm not quite so slick ;)

Can't wait to see this thing running!

Thanks David, been following your track builds for a while, they are a great resource for a first time builder like myself. Hope to experiment with your track painting method once I get all the lanes routed and braid gains completed. Having a realistic looking track surface is important to me. Really like the look achieved on the tracks built by SlotMods, any idea of the methods they use to paint their tracks?
