Temptress Build
wow. getting enough timber to build a temptress is hard.
no one in this country (Australia) seem to stock much Mahogany or Mahogany equivalent.
best I can find is Sapele imported from Africa.
Sapele Prices, for those interested.
Enough 25mm timber to glue together and cut all the frames out of. = $1970 in rough sawn timber
25mm thick timber to re-saw into 6mm planks for bottom planking and external side / deck planking
= $6860 + $2500 to have the timber re-sawn and dressed.
$1000 shipping to get the timber to where I live.
all the plywood, MDF and Melamine = $2770
I still need to get a quote for all the other timber in the boat. (stringer, keel laminations, chine rails etc.)
which I'm guessing will be about $4000
so approx. $19100 Australia dollars in total.

Slow progress on cutting so far... Have managed to get through the 9mm ply, chines and part of the solid wood, all looking good. Unfortunately, now grappling with some file corruption issues. Dan's on it, and hopefully nothing serious in my process.

Michael - That does not look like slow progress to me. Motivating for me…
Well, slow in comparison to other projects I have on the go.
Word of caution, there is a lot of CNC parts for this, and does make it much easier/straight forward to build, but, if you were considering hand cutting all the parts, I would suggest researching a local CNC machinist to be your best friend!
I have mocked-up frame two, and all looks like a tight/neat fit. I won’t be making frames for a few months yet, but it’s progressing well.
More photos soon…

Progress across the build. Have managed to get all the solid wood parts cut as well as the 18mm Plywood bulkheads. See a mock-up of Frame 4 below. I love working with CNC cut parts, such accuracy and takes the variability frustrations, and workload, to new levels 🙂

Looks great, Michael.
Curious. Do you plan to finish the boat in Singapore, before moving to Perth? Or will you ship the parts and finish in Australia?
PS - I love my Shaper Origin, but the speed of a full CNC router table cannot be beat.
Andrew – With respect to the price of Sapele, I did find a way to save $ on the hardwood frame lumber. I ordered 4/4″ roughcut Sapele in random lengths and widths. The boards were 6″ to 12+” wide and 10-12′ long. The price was US$9.70/board foot, and the lumber yard only charged me US$80.00 to plane the boards to 7/8″ think and run one side through the joiner. (S3S) In total, I purchased 170 board feet of Sapele
They only took 1/16″ off of each surface, calling it hit-or-miss surfacing. In the end the boards look great, for frames. This was a cost saving from purchasing 6/4″ rough cut boards and surfacing them down to 7/8″.
I also am not edge gluing my boards, and instead using the Shaper Origin to cut multiple parts out of each board.

Looking great guys, it is really cool to see some of these parts coming together in physical form now! I am trying to get Michel Berryer to sign up to the forum, he would love to see the progress you guys are making.
Re timber, Sapele is a great candidate, technically a cousin of mahogany and I almost entirely use it for the work I am doing at the moment. Grain can vary considerably but you can get some really nice, tight, straight grained boards which are perfect for boat building. The deck I did on the Tideway (pic below) was all Sapele, I selected a tight grained board for the central planks and some charactered, book matched boards for the covering boards. The colour also matched well with the original “proper mahogany” on the rest of the boat.
Also a little tip that I used when making Chris Craft frames that massively saved on timber wastage. I cut the frames out of rough sawn 1″ stock, which actually usually comes in at 28mm. Then I thickness just the parts I need once they are cut out, I do this in my drum sander as it is more delicate than my 1960’s thicknesser. Because I am only thicknessing the width of a frame and not aiming to flatten a 12″ board I usually only have to take off minimal stock in order to get it clean. I can usually get a clean 25mm frame out of a 28mm sawn board, very efficient. Usually a machine shop will specify 6mm or 1/4″ to clean up a board from sawn so I’d end up having to buy 32mm stock then.

This will definitely be finished in Perth. I'm likely to only be getting the frames put together up in Singapore and it also makes it easier to move as the frames are essentially flat packed.
Spent quite a bit of time getting my head around the STEP file model today. It's much easier to view each frame isolated in the model than studying the 3D plans.
Hi Andrew.
I am also in australia and very interested in the temptress boat ive been in contact with Dan he told me about somebody else in aus building one.
As yet i havent purchased the plans.
I was hoping to get a rough idea as to how much timber is required to get the frame built.and what type of timber is alright to use in Aus.
Any advice would be welcomed
Regards
Darryl.
Ps absolutly love tassie been there many times.
