You are very kind. I am a vertically challenged guy; however, I can fit in any car and as part of my Irish Heritage, I would have been valued for being able to work in a mine or pick potatoes so my height is OK. The link for legroom is great for all of the information he shared. I have never seen that before. I was thinking about cutting the pedals down if I find them to not be comfortable. I have shortened pedals in my Dune Buggy and it created much needed foot room.
I have a sandblaster, I have sandblasted. It is miserable work. I gladly paid to have this work done. I went over where he needed to be careful to not create too much heat and warp the flat panels. There are two ways at least to reduce heat, actually many more. If you are using sand, how course (fine vs rough) can generate various levels of heat. Air pressure has a real effect. Reduce it on the parts you are worried about. I am not sure on actual pressures. Also you can keep the pressures the same and just back off the work piece to reduce the cleaning. Also a whole other discussion is the media you use. At $85 an hour he does 5 x's what I can do in the same hour.
The roll bar is NOS from Alabama bought 30 years ago. It may not be used as the seat travel is killed with the seats I am planning on using. We are going to see if we can modify them when I get the bonnet back and we do a mock fit and it is back at the fabrication shop. I think the car needs one. I am almost sure this one can be changed, but my buddy can fabricate faster than he can modify.
I think I used a 3 M product on the bottom. I applied it only to the bottom of the tub and right inside the fender arches. I will paint over undercoating, I have tested some area and it seems to hold pretty good. The car will see limited usage so wear and tear should not be too bad.
I built a Berrien Dune Buggy with an Orange gel coat. It is a Manx clone. It has a tube chassis with a fiberglass pan that looks like a stock floor. I have a complete build on it as well on the SAMBA website. The motor is a stock 1600 with a single carb. It is slow but reliable. I have a Tri Mil jet coated exhaust that is fairly quiet. I really love my DB. My grown kids even enjoy it and the grand-kids think it is a toy.
When I am at a car show it is always popular with everyone but the street rod guys. (Most of them bought what they drive so I don't know why they look down on it. LOL)

This is my photo site for the Berrien Dune Buggy.

It is as close as I will ever come to building and designing my own car. I hope you like the pictures if you check it out.
Amazing! The documentation and commentary is superb - I've got a lot more posts, but you sure beat the heck out of mine in terms of content. A few questions, and one comment:
- have a look at
https://www.peterrenn.clara.net/midget.html#legroom for what he did to fit his feet, legs, and pedals-
- what pressure did you sand blast at? I've been terror stricken to sandblast anything other than structural due to warping worries.
- where did you source your roll bar from? Do you expect to lose seat movement? I want to add one for protection against getting t-boned. Advice requested.
- what are you using for undercoating?
-and which dune buggy? We've got a Meyers Manx clone on a 62 chassis with a 1600, and dual kadrons and a SuperTrapp type down facing muffler on an 'off-road competition exhaust system - with the exhaust and kadrons only for the 'ooh - shiny!' factor
Thanks, Doug
