I use a speed square to draw my degree%. In this arch I had 19 pieces. Because of the inacurracy of the speed square I rounded to 20 pieces for

the math. I am tiling an arch so I assume 180 degrees, divided by the number

of pieces used,= 20. This comes out to 9 degrees. The other factor is that there

will be a cut on each side of the tile, 2. Divide 9 by 2 and you get 4.5 degrees.

Draw this out on a piece of tile and cut it into a jig,...see pic. This belongs in

tricks of the trade lol. Cut your pieces to the needed size to fit your radius

and then run them through the 4.5% jig.

Every arch is different, as well as tile sizing so each one is a new challenge

On the jig, notice I didn't cut at the first line drawn, the skinny pie shape, rather paralled and cut further into the tile. What this does is leave you more

tile to work with (on the jig) so you dont cut it in half.-Hamilton

It never ceases to amaze me the things I can learn on this forum.Without jacking the other thread I wanted to ask some questions being that this subject deserves its own space.

Alright Jack,if Ive got a medallion(360 deg.)and lets say Im gonna wrap it w/28 4'' pieces.So first i divide 360/28=12.857143.Ok,lets cancel 28 pieces and use 30.So thats gonna be 360/30=12.12/2=6.That would leave me with 6 degrees on either side.Am I doing this right?Also,for a circle I guess you would have to measure the perimeter/circumference(whatever the circular distance is called!).Lets just say its 12 feet all the way around.This gives 144 inches.144/30=4.8.4.8 converted to inches 4''and 7/8-16th(joint)4'' and 13/16 cut at 6 degrees on both sides.Am I correct?:bow:
