Icefang,

You would get more help if you said all of these things in the beginning in detail. I could really assist you if I had something to go on. it's a bit of work to write a complete and detailed message that takes the one advising as far as possible so that simple and obvious questions have been eliminated.
Gonzo kindly asked what you were doing, but he should already have been told.
In any case, in another thread you were told (by at least myself and PAR) to copy the old mast for best results. You need to say whether you yourself will be doing the work or you'll be having it done. Nearly all wooden masts are made from spruce, fir, or pine. In the USA, the most popular would be spruce, followed by fir, and then pine last of all.
the builder first sources the wood. It's possible to use a single piece of wood and it doesn't need to be perfect but it should be straight and seasoned wood. Otherwise it can be built up from laminations, which is more labor.
1" laminations would work, but it would be faster and just as strong to use 1 3/4" laminations. Then you could look for 2"- 2 1/2" air-dried spruce or fir in lengths of 16' or so and scarf pieces end to end.
The building of a spar is quite easy for an experienced boat carpenter, and even you might be qualified to attempt it (though you haven't said anything in that regard).
Luckily, all the hardware is there, or I assume it is. What is the boat, is the mast deck-stepped or keel stepped, is most of the original mast alright? Then it can be added to and saved, which is the easiest choice of all.
The upper mast is the hardest to build so rot at the bottom is easiest to fix. It may be that you don't need a new mast at all./
Fang, it would be fair if you wrote at least as much in response as I've juist written for you, answering each question. I'd like to help but you need to tell a more complete story.

the mast is steped to the cabin forward you can see the step in the pic. the old mast is to far gone to save. the mast was on top of the cabin while in storage with a tarp over it the water got in over the years and ran the whole length of the mast.(years)not salvagable.also the preveos owner cut it in half. it is solid, i know a hollow mast is lighter but is it nessessary on a gaff rig the ast is so short.

Get a boat glossery and bone up on terms. Then describe everything about the boat itself. Describe the original mast in terms of fittings, spreaders, and so forth. Describe the boom attachment, show close-ups of everything, and be complete, and please use the actual nautical terms for everything.

It seems that there is enough left to copy. With a solid mast it should not be a problem calculating wall thickness.

The mast can be solid. You need to decide what method to use (one piece "tree trunk" or several laminations). This will depend on your experience, finances, and availability of materials.
I'm guessing your boat is around 22-26ft, but all depends on the hull design. There's no such thing as a "short" mast, only a mast that is short for the boat's length.
Any case, the new mast should be a carbon copy of the old one. Was the original one piece or laminated?

as i said in my other thread the old mast is laminated, 1x6 spruce glued and shaped round. well as the pic shows the mast is history. is laminated stronger if so i am willing to spend the time and money to build one. yesterday i went dowm to the beach and cut down a stika spruce,and today ill peal it and shape it to fit for now. im going to have to weild up my own stainless hardware. my next job is the keel its steal ive scraped and grinded it down now finishing any sugestions.i was going to tremclad and then varathane for now.

I wouldn't bother shaping the tree you cut since it's wet as can be--- meaning heavy. Give it 3 years to dry out or have it ripped at the mill and wait a year for the stock to dry.
What hardware is missing that requires you make new parts? Few parts made from metal are needed if the pictures are any indication.
Laminated vs one piece? The laminated stick is somewhat stronger but the one oiece is strong enough. In the old days all masts were tree trunks and they were quite strong.
If you need a temporary mast, laminate one from 2 x 6 spruce lumberyard stock using four layers. At least it will be cheap and light. A quart of epoxy will be sufficient. You might want to invest in a power plane.

to late the mast is steped wet. i cut another one today and will let it cure banded and raped in perlap. need to be on the water today. i know its crazy,but i am. it can dry up there. i know now that lam is stronger if i have the time on this planet i will build a mast but i have sailing to do.

I am not sure if you are asking how to build a new mast or repair the old. I have never built a mast, however I have made two pair of oars using the "Octagonal Hollow Core Birdsmouth" method of making a long strong cylendrical object and I understand it is a method of making masts as well, just larger pieces of wood.

I have an article and pictures written by Joel Herzel in a magazine several years back, he was kind enough to help me with it and it simple and straight forward way of making oars or masts as the case may be. If you would like a copy and link to the pics, please email me direct.

I would say this. You would need a pretty well stocked (with tools) wood shop. At the very least a good table saw and router table.

Regards,

Tom...
