Howdy All,

I need some of your combined experience, thoughts and opinions.

Whilst discussing some minor space limitations my proposed future workspace (read: Garage) may present, a work colleague suggested that I mount the building form to a framework of 2"x4" stock, which itself would be on heavy duty castors.

By placing crossmembers at each point the form legs attach (plus many extra cross beams for strength), the form should be resistant to twisting stress, with the added bonus that the boat frame and form can be moved to the center of the workspace, and then moved back against the garage wall whilst we are not working.

Is this idea pure folly?.........or am I (happily) reinventing the wheel?

I look forward to your thoughts.

Justin

Many people build their forms with casters to allow them to move the boat around in tight quarters. There is no folly in using a 2x4 framing. Just be sure you are well braced. The boat at best will weigh 600-800 lbs when you are ready to flip which is not much weight at all.

Few things in the world measure up to the thrill and satisfaction of boating in a boat that you built.

If you can, don't move the boat until you have the base frames, keel, sheer and chines assembled. The shape is a bit flimsey until then. On the sheer I mean the first full length piece on each side. KH designs have several pieces to a heavy sheer log.

I used a autobody cart that was made for pickup beds and then built my building form on it.
It worked pretty well, and having it on casters is definately the way to go. It was totally adjustable.
I believe it was made by Summit. After I'm done I still have the body cart!

Thanks to Dave, Bill and Robert for your thoughts.

Having measured up 'my' half of the garage, I have a total area of 21 feet x8 feet, so the trolley concept is definitely the way to proceed. Having only 12 inches clearance on each side isn't a very work friendly environment!

Pondering Bill's thoughts, perhaps I can devise a way of securing the trolley to the floor when the sheers and chines are applied, to provide extra stability?

Thanks again to all,

Justin

I mounted my central 2x4 timber of my building form to the floor with some anchors that were only sold at bolt & screw shop,not at the common big box stores(don't know what you have down there)

You drilled a hole in the concrete,set a sleeve in the hole,positioned a tool(rod) in the sleve and hit it with a hammer to spread the lower part.

There are common threads in the sleeves that I bolted down through my 2x4 to secure it.

when I removed the 2x4 and bolts, there are just threaded holes left that can be reused.

These could be used with eye bolts and turn-buckles to hold a form on a dolly secure

Hi Jamie,

Thanks for the link to Tim Major. I've now made contact with him and had myself placed on the Australian Builders register. Apparently I'm the first Barrelback-19 build to begin down under...is this true? Surely not.

............now I'm wondering why this might be?

A question for you. What timber have you used for your frames? I've pretty much 'almost' decided on using Victorian Ash (Eucalyptus regnans), also commonly known as Mountain Ash, Tasmanian Oak or Stringy Gum. Primarily as it's native to Victoria, and grows to 230-330 feet, so board length shouldn't be a problem.

Keen to hear what you decided on.

Justin
