Welcome to the forum Uncle S - Rob

Hello -

I'm a new member to the forum. I've been woodworking for the past three years now, and I live in Dallas TX, but I'm originally from Alton, Hants. I immigrated about 25 years ago, but the ol' satellite system keeps me up to date with things back home.

I'm mainly interested in early American furniture styles, Chippendale, etc. and my next big project will be a reproduction of a Highboy (a la New Yankee Workshop plans) using curly maple.

If I can answer any questions from this side of the pond, let me know. Bear in mind that we're still using the imperial system here (what ? ) but that's just the way things are. Can anyone help me subtract 7 3/8 from 13 5/32, and then find the midpoint of the piece lol.

Thanks all...

Spanky

throw the 5/32 to one side,

subtract 7 3/8 from 13 =5 5/8

5 5/8 =(5 20/32) + 5/32 = 5 25/32(5 50/64)
5 50/64 d x 2 =2 57/64. (64/64+50/64=114/64 dx2 =57/64 +2")

i did this in my head & had to think about it ---but on paper should be easier.

via calculator.--
1/8=0.125"
1/16=0.625"
1/32=0.03125"
1/64=0.015625

7 3/8=7.375// 13 5/32 =13.15625
13.15625 -7.375=5.78125 dx2=2.890625.(.890625 d x 0.015625=57)

look no further than here for reference charts

Did you know that you can enter "13 5/32 minus 7 3/8" into google and get the same result :wink:

No i didn't know that,but then i never found a workshop good for electronics,the amount of shop stereos' i've been thru is terrible,Hmmn google eh!.That calls for a wi-fi hookup in the shop.No forget that --no work would get done.lol.






I just tried it & i got a load of old piffle --how did you do it ?.

You need to put in number followed by a space then the fraction followed immediately by a minus sign (-) followed by the second number and fraction as before. The answer is decimal though (5.78125) which is 5 25/32.

Hello Uncle Spanky - I won't ask :shock: I don't want to know :^o

Thanks for your little brain teaser. I always thought that was why tapes had imperial on one side and metric the other. So in your example:

13 5/32" lines up with 334mm and 7 3/8" is about 187mm,

so, 334 - 187 = 147mm

then half of 147 = 73.5 mm which lines up more or less with 2 7/8"

I appear to be about 1/64" out which is 0.4mm - the thickness of a pencil line.

Of course if measuring out it wouldn't be necessary to do the conversion back to imperial - you can just mark out at 73.5mm.

Or do i do it this way cos I mix up imperial and metric without too much problem?

Thanks for the warm welcome everyone...

Glad that the brain teaser got some grey cells moving again...I'm off to watch the football now...My beloved Saints are away to Man City in the Cup. Fingers crossed...
