Jakobud DK plan discrepencies.... other plans available?

[rbarr110]

So I was in the process of re-creating the jakobud plans in AutoCAD, since it is much easier to print to scale in AutoCAD than trying to make a jpg or eps file print to scale.

Well in re-creating the plans using the dimensions there are lots of discrepencies, particularly in the height and radius of the arcs.  For example, left side height added up is 64.75" and the right side adds up to 64.93".... not a huge difference but makes the precise autocad drawing way off.  There is also one missing horizontal dimension...not a big deal but can be figured out by working up/down from all directions.... becomes a problem however when vertical dimensions are off.

See attached picture for particulars..

So after all that, are there other plans avaialble out there that I can try to reproduce for my own use.

I hear you.  I've been trying to do a Pole Position cab in SketchUp from Jakobud's plans and a broken cab, and still run into some problems of not adding up.

However, to bring it into prespective, a quarter inch difference over a total of 64" is less than half a percent off.  Not bad for hand messurements; in fact that's very good.

Part of the problem is the numbers shown on the plans probably are not really exactly 18.75" (or whatever), but something pretty close that it looks like that.  Are the numbers with or without (rounded) T-molding?  Were the vertical & horizontal calculated from angle + length, or plumb bob and right-angle?

Part of my problem is the original cab I'm going off of is damaged (the whole reason I'm recreating it), so sometimes I'm estimating plus or minus 1/4" over about one foot, and +/- 1/2" over three feet.  That's closer to 2% and 1% range of error.  I've tried fudging the numbers adjusting it in cad, but everything I've tried has looked a little off to me.

I'm not sure how good or bad the cab the numbers jakobud got was, but add the not-manufactured-at-easy-fractions to the hand measuring of possiblely bad cad, and 0.4% error isn't bad at all.

I know, not the answer you wanted.   But just saying jakobud's plans are damn close, so try fudging it around in cad.  And I'd rather have the raw, but doesn't add up, numbers, than numbers guestimated at so they do add up (but might be guestimated wrong) and passed off as prefect.  (Some day I'll get off my backside and just do it, too. )

I think the discrepancy lies in the fact that I believe these cabinets were made in metric, while the measurements were made in imperial.
I don't know for sure, it's just a guess.

I'd bet if the measurements were made in metric, the two vertical sides would be off by ~1/2%, too.  I've tried measuring my cab in both metric and imperial, always ending a little off.

I'll have to measure mine up. I've put it into CAD, so I can find out how CAD compensated for the discrepancy.

EDIT: First point of note, on your math of Jakobud's plans... on the back side (left) you missed a measurement at the top 0.75".
The left side should be at a height of 65.25", it still leaves you 0.32" off.

Actually I didnt miss that 0.75 measurement.  If you look close to the measurement, the extent arrow for the 63.25” measurement goes all the way out to the edge at the top of the side panel for the cab, the 0.75” measurement is the setback for the location of the top of the cab surface.  Regardless, either way the dimensions are off. 

The more I look at it, I wonder if the program used to draw the plans was rounding on its own for the dimension leaders.  The dimensions aren’t consistent with the number of decimal places used.  For all I know a 3” dimension on the plan is actually 3.03” (77 mm) but is automatically rounded down by the program.

OK, trying to get the plans drafted up and fudging the areas to get it to look right without knowing exact dimensions.

One area in particular has me confused, along the bottom of the marquee, where I have the question mark.....

Theere is a flat surface that measures 1.5" on the vertical but has no horizontal dimension on the jakobud plans.  I have pulled up dozens of nintendo cab pics on the net, and I dont really see a flat area like shown on the plans.  It looks more like a very large radius turn.  Could someone verify for me?

Thanks

A friend of mine is desperate to make a DK cab but he can't find any plans online, do you guys know where I could get some plans for him?

[CheffoJeffo]

I know that I am going to regret this post (and nothing to do with the OP or Jake) ...

Jake's plans are the only freely available plans that I am aware of. They aren't quite accurate and Jake freely admits this -- he didn't measure a DK cab to make those plans.

There are folks who do accurate repro Ninty cabs, but I am not aware of any of them selling plans.

There is, however, this one guy who claims his plans are accurate, but he is just reselling Jake's plans (I still have screen prints of his eBay listings) and, when uncovered, he waged a war against those who called him out. He has been banned from every arcade forum out there and threatened to sue them all for people posting about him. He has threatened to sue me personally and launched a tirade on YouTube against many collectors, myself included.

To my knowledge, nobody has accurate DK plans available, even for sale.

If you find someone selling plans that claim to be accurate, I strongly suggest a quick trip to Google before getting too excited.

* CheffoJeffo wonders at the strangely obtuse nature of this post and remembers that he doesn't run this place and the last time he posted about this guy, other people were affected.

Many thanks for the reply I appreciate you taking time to explain what seems to be a very odd situation regarding that seller. I will pass information onto my mate and point him in direction of Jakobud's plans.

I have built from the plans that Jakobud has hosted.  Yes, there are some discrepancies but but nothing that can't be fixed on the fly in the woodshop.  They are an excellent road map and anybody who feels comfortable screwing two boards together should be able to compensate for the idiosyncrasies and still have a great looking cab that is within an inch of the original model.  After all we're recreating not counterfeiting.
