Opening T Bucket Doors in Fiberglass Body How-To

How to Put a Door in a T-Bucket, T-Bucket Doors that Open, Part 2

Recently, the subject of opening T Bucket doors has become a hot topic on social media. And there’s good reason for that. Maybe it’s the aging T-Bucket population. Hey, when a hot rod is that good you stick with it! Or maybe it’s as simple as making it easier for passengers to get in and out.

Bob Hamilton continues where he left off in Part 1 of How to Put a Door in a T-Bucket. This is a very meaty subject that we can only highlight in print. Bob covers opening T Bucket doors in much more detail in the very informative T-Bucket and Model-A Hot Rod Mod’s DVD available at our sister site, StreetRodPlans.com.

Follow along to see how you, too, can fabricate opening T Bucket doors. And at the end of this installment we’ll outline how much more detail is covered in the DVD if you want to see exactly how it’s done to ensure your opening doors will be trouble-free.

Building Opening T Bucket Doors, Part 2

“After laying up flat pieces of fiberglass on the table, I cut them into strips 1 1/4 inches wide with a band saw. Next, they were trimmed to length from the top of the door to just where the radius for the bottom was to take place. I decided to round the bottom corners, but I could have made them square also. The strips were set in fiberglass bondo and 90 degrees to the door. I cut a piece of a bondo spreader and sanded a radius on one corner and then ran it along the fiberglass bondo (NOTE: fiberglass bondo is the shorthand term Bob uses for fiberglass reinforced body filler) where the strips meet the door. This gives a nice fillet on both the inside and outside. After the bondo was set, I lightly sanded the fiberglass bondo and then laid two layers of fiberglass mat on the inside and the outside. This makes a very strong addition to the door.”

“To get the rounded corners, I cut a piece of 1 oz. fiberglass mat that I laid up, and then curved it around on each corner and attached this with fiberglass bondo and held it in place with a couple of spring clamps. This was done prior to adding the two layers of fiberglass mat. This way both sides can be laid up all the way around the subframe at the same time. When everything was cured, I trimmed the excess with an air saw. I use an air saw because it is small, easy to handle, quick , and a lot easier to control. With the excess trimmed, I took a long board (sanding block) and dressed everything and made it square.”

“Now I took the fiberglass that was laid up in the 2” angle iron and cut, trimmed, fit, and attached with two sheet rock screws for alignment. I made cardboard patterns for the corners and then transferred these to fiberglass mat that was laid up earlier. Here you could use two layers or three. I used two layers. These will be held in place with fiberglass bondo and a couple of spring clamps.”

“This picture shows everything in place using fiberglass bondo as the ‘glue’.  Notice the clamps holding the corners and the sheet rock screws holding the long pieces. Also notice that I added a couple layers of fiberglass at the top of the door to bring it closer to the same height as the sides. Where the angle fiberglass pieces bond to the straight pieces, there is a natural rolled space, this is a great place to gain additional strength by filling in this area with fiberglass bondo. After everything is set up, use a sanding block or small electric sander, and smooth everything out. When the finish work starts, I use ultra-lite bondo to work everything smooth and nice for primer.”
