Building my MT 26 folding tri

It will be interesting to see what he says. The fuller bows aren't a bad thing though, they may be necessary to carry the designed rig in the full range of conditions. Did Ed give you any other builders names to contact? It might help to see what other people have done.

 

Not yet, It was so blunt that the stringers would have to be steam bent. Really had bad lines, not like the plans showed. I guess I should have taken a pic before I cut the frames loose. I think that there is sufficient buoyancy with the fair lines. When I first e-mailed Ed he returned the message saying that I needed adjust at the stern. Just didn't make sense to me. I wonder if he was confused about what I was telling him. Michael..

All I know is that my sail # is 105, I hope that the other 4 have some experence in building boats. I have found 3 other mistakes in the plans, being incorrect numbers in the spec's.

 

Also, by the plans it calls for webbing from A-4 to the stem. Maybe that's enough for support with the added distance after frame re-spacing. The distance is now an extra 18" more from the stem to A1.

 

I'd loft it to see how the lines work out. The Gougeon book has a good description of the process. Ideally if Ed says oops the frames would be reduced in size and kept at the designed locations. Maybe he was thinking of laminated stringers....they do look deeper in section than I expected.

 

I have not glued and screwed anything forward of A4 until I hear back from Ed. In the one pic you can see where I cut the frames loose. Then imagine bending in the stringers. It would go from 16 1/2"width to the stem in 20". I really curious about what Ed will say. Michael..

 

Your lines don't look bad, the wood has a way of showing the fair curve. If Ed says keep it he'll probably have you put in the extra frame. Avoid a hollow by making it a little oversize to start the fitting process.

 

I told Ed that I would loft & in-put the numbers into my Cad program to check the lines if this is wrong. Still waiting to hear from him, maybe tomorrow.

 

There was a hollow between A3 and A4, but now it has disappeared after the frame space mods. I think I'm right on this correction at the moment. He may tell me I'm wrong, but we'll see....

 

Good idea, I still loft old school... keep us posted and good luck.

 

Will do, I have to work tomorrow putting a tongue & groove ceiling in a log house{retired General Contractor of 40 years}. I thought that retired meant that you didn't work anymore. Ha Ha...Michael..

 

The only picture I've seen online of a MT 26 was listed for sale as a MT 28, it may not have been a typo after all. Also is there a clipper bow option and a LB option with this boat? If so maybe the first frames are listed wrong. Rick

 

Also search craigslist and ebay for trimarans, there was a Horstman 25' built 2002, sold cheep in GA. I missed that one , now looking at it,s folding system it could be a MT 26. If it is you may be able to find the builder. Rick

 

I think the MT26 just came with the plumb bows as a newer design, maybe the MT28 was just the 26 stretched when the other builder encountered the full frames.It would be a hotter fix. One building technique for bending deeper stringers is to rip the section to be bent with a narrow kerf blade but leave the rest in one piece. This lets you laminate where you need to without the alignment and clamping challenges of doing the whole length of the stringer in 2 layers.

People with skills never get to retire Michael Don't spend all day looking up!

 

True, MT26 only has long water line bows. Still no word. Off to work. Talk at you tonight......Michael..

The MT26 is a stretched version of the 23-25, probably where the problem started with the lines. I've seen it happen before on other stretched models.

 

Got the news, I got it right....Now I can go forward with the build. Will be adding another frame. Ed will add an additional frame on the plans. I'll give myself an atta boy for this one..Michael..
