Using Sketchup, I had drawn a lot of possibilities for a 12 Rhombus combinations. Here is the photo of the one I like…
Cutting the rhombus.
Then, next step is cutting the rhombus. I set my compound saw to 30 deg then cut so many pieces one by one. Thanks for Daddy (Dad-in-Law) who also helped in cutting them. I could not find a photo..
Sorting out according to colors and blend will shorten the time. Also the correct thickness will save time.
Gluing technique: I use a transparency (scrap from the office because it is not printable type but only for copying machine..zerox) underneath so the glue will stay in place and will not be dripping. The transparency will be very easy to peel off when dry.
I make a jig to hold the coaster in place… I have only two hands that are required to control the sanding using an angle grinder. I set the speed to the lowest but the torque is affected. This is nice experience. I started using a power tool…. Doctor reminded me not to use grinder. Okay I have to be careful and therefore two hands are used. Thanks for the jig I made. It helps a lot.
This is the jig…. the rubber is strong enough to clamp the coaster. It is quick and easy to use. No screw to tighten.
I use sanding sealer and spar varnish for two coats. Sand in between with 1000 grit.
I have made a lot… batch by batch. The first group that I finished was for Christmas gift. Around 160 pieces of coasters been sent out. Agnes has packed out 4 pieces per gift. They love it. One set of 4 pieces been had travel to Amsterdam. She loves it very much. BTW they are all free. About 5 sets of these have been inside the escabaña box and also a gift to my special friends.
My only consolation in making these coaster is the joy and happiness that the receiver had. They love the gifts considering that those were made from labor of love.
I still have stocks for the next batch.
Till next. Have a nice day.
