problem,finding reasonable solution cost vs value

any time your presented with a 'problem' you have to mentally step back and ask yourself

(1) do I need to solve this, to proceed?
(2) is it worth my time, effort and the potential cost solving the problem will incur?
(3)is this really my problem or some one elses, that they need to solve?
(4) do I have the tools and knowledge to proceed or should I outsource the issue at hand?


my brother -in-laws got a 29 ft boat he purchased to rebuild , he purchased reasonably with an originally trashed engine,
now the problem is he has nothing but an AC cobra and a Toyota hybrid to move it with'
now all projects seem to result in UN-expected minor problems you might not have expected going into them and this is no exception.
the Toyota hybrid he owns can barely begin to move the boat on the trailer,
as it easily weights two to three times what the Toyota hybrid weights,
so we will need to use my kabota tractor to move the boat & trailer around my yard.
naturally the Kabota tractor has a equipment hitch but its not the type we can slide a common 2" hitch into.
Ill need to use something similar to this \ the trailer tongue weights only about 100 lbs but pulling it with the hybrid is basically hopeless

now the kabota tractor has an accessory hitch but the female socket size is not compatible with the common 2" trailer hitch, female socket size is something like 2"x 1.4"
so Ill have to fabricate a custom adapter, a few quick measurements show

that two 4 1/2" long 3/4" grade #8 bolts and nuts and washers
$10 at most local hardware stores covers the two fasteners and washers & nuts

and a couple 13/16" holes drilled in the trailer hitch pictured above would allow the tractor to have its current trailer hitch adapted. now its not sheer strength that dictates the use of the bolt size as much as exactly matching the existing ,kabota trailer hitch, BAR, but none the less, a couple bolts will be reasonably cheap.

that leaves drilling the two 13/16" holes in hard steel,
my brother-in -law got quoted $35 to drill the two holes required,
locally at a machine shop
a drill bit will cost a bit north of $23-$25 so $35 to drill the holes is not really absurd.
the potential other option, of welding the two components would ruin the ability to interchange tooling,
so the basic cost of having the ability comes down to about $35-$45 to have the ability to use the tractor to move the boat, which seems rather high for a problem thats very temporary in nature.
the one problem for a tool junky, like I tend to be,
is I see the choice a bit differently than many guys,
Id rather buy the tooling and do the work myself,
so I own the tools (BITS) the $15 saved is nearly meaningless,
but saving $15 and now, and owning a new $23-$25 drill bit ,
now having mentally gone through the check list posted early in the thread,

I find I don,t YET have one tool handy,too immediately complete the custom fabricated part required, but the potential problem is something I can easily fabricate a custom part that solves the issue, and its not really 100% my problem

as a result seems like a no brainer to me!
my b.i.l. needs to pick up a couple bolts washers nuts and a high quality drill bit
if he wants a custom fabricated part made.

I like small odd projects Grumpy.
Keep you busy today .

BIL needs at least a 1/2 ton pickup 4x4.
 
If I'm getting this correctly it sounds like you could just drill a couple 1/2" holes in the draw bar, file them out a little so a 1/2" bolt will slide through and use a drill bit you probably already have. The extra clearance on the holes of the tractor receiver will allow you to be off a little one way or another on your hole alignment when drilling the drawbar and you're not going to do anything but move the boat around the yard at low speeds so any movement of the drawbar in the receiver won't be noticeable, cause wear from extended use, or have any adverse effects. No need to buy special bit or pay machine shop and 1/2" hardware will be cheaper.
 
keep in mind
I own a decent, MILLING MACHINE , in my shop, which I obviously like too use occasionally

the guys at the grizzly site (tech guys) were friendly and helpfull, and understanding)

and this "problem" from my point of view, is very minor and while it can obviously be cured exactly as you describe!
I would vastly prefer to correctly match the bolt size too the current hitch bar holes plus in the process add a new drill bit to my tool inventory.
any problem you can solve for under $50 and in UNDER 1 hour and gain new tools in the process is a total WIN/WIN, in my opinion

no rush, as soon as he buys the drill bit..
 
You got suckered by your B.I.L. It sounds he bought this boat with the intention of YOU rebuilding it.
Refer to #3 - (3)is this really my problem or some one else's, that they need to solve?
Looks like you got a boat rebuilding project Grumpy.
Disown him and his hybrid driving ass.
 
Grumpy is not like that Mike.
He is Loyal to the End like me here.
 
Well I took it like his BIL said to himself, "Hey, I know of a really handy guy with all the tools
and a big shop, who is just sitting around waiting for me to give him another project. I would
actually be doing him a favor."
Don't get me wrong. I will HELP anybody. But HELP means that the project is theirs and I
give assistance and guidance. Not me doing all the work while they watch & drink beer.

When he's not looking Grumpy, install a NOS Fogger system in that Toyota.
