Another Aussie Zip!

Post by Lachlan1 »

Starting this thread so I have somewhere dedicated to post my Zip progress. I have posted some of these pics elsewhere but I thought it would be good to have them all together.

I live in Australia and I’ve decided to build a Zip. I managed to get some Tasmanian Blackwood a couple years ago(maybe more than a couple) and decided it would make a nice boat. My father-in-law owns a sawmill that I work at a couple days a week so on a weekend we went down and milled the logs ourselves. After that I brought them home to sort through and pick out the best pieces.
<insert 8 years>

Finally getting around to the build now during the lockdown here in Melbourne.

Just started machining the Blackwood today, very excited when they Grey rough sawn hardwood started coming out of the back of the thicknesser showing promise. Still waiting for the plywood to come back in stock but I’ll hopefully have all the frame pieces cut before that arrives.

Another couple pics of today’s progress.
Started tracing the frames onto the Blackwood, trying to avoid any defects in the timber.

I have also attached a photo of some of the Blackwood I used on a canoe I recently built to show how I hope my zip deck will come out.

Wow, Beautiful! When you mill your own lumber you take home-built onto another level.

For some reason I suddenly feel better about my Dewalt 735 planer :D
Beautiful lumber!!! I look forward to seeing it become a boat!

Blackwood is awesome! I've made knife handles out of that stuff--should make a stunning boat!

Perhaps the slowest Zip build in Glen-L history...

So I gave up on waiting for the expensive plywood I wanted to use. Gone with a cheaper brand that I can get locally (big green shop :D ).
I was on the fence about fibreglassing the hull but now that I’m using cheaper ply I have decided to fibreglass and paint the hull instead of leaving it bright. Also makes sense when u think that I’ll never be able to match the Blackwood deck to the plywood sides. Thinking I’ll paint it black with a white/blue pinstripe waterline and maybe a retro graphic on the sides, although I’m assuming I’ll have a while to decide on that.
I am also now thinking of hanging a 40hp Suzuki 20” on the back. They come in at about 230lbs so I’m definitely going to have to beef up the frame to handle it. The Yamaha 30hp/40hp wasn’t much lighter and they sell the Suzuki as a 40hp/50hp so won’t be running the engine too hard under normal conditions. I really like the look of the short shaft but the Suzuki doesn’t come in a short shaft for that model.

Building form has been ready and waiting for a while now but hopefully now it’s full steam ahead. Started cutting out the plywood frame members today. Got all the gussets, stem, transom and breasthook cut out. At this stage I’ll leave the transom a little oversized to accommodate the 20” outboards if I end up going that route. I’ll hopefully get all the frame members cut out in the next couple days and if I can get some glue by the end of the week I might be able to start attaching frames to the form. :D

Hi Lachlan, I like your plans with the blackwood vs paint. I am thinking of doing something similar on my TNT with a mix of Mahogany and paint. I did use okume plywood, but I still don't really like the look of it and would prefer to paint so I think you aren't missing out on anything with your plywood choice.

I also bought a 9.9 hp suzuki and ran into some surprises when I hung it on the transom for the first time. I also realized the wiring harness included some functions that the motor didn't actually support. So I had to tear apart my harness and do a lot of reconfiguring of my electrical.
The Suzuki dealer shared with me a link to their rigging manual which would have helped me avoid these issues.
Even the 9.9 has a mounting bracket that is way bigger than my 1.5 in thick transom. I had to beef it up with and extra lamination of 3/4in plywood so the clamps could grab properly.

Hopefully this helps you out a bit:

That is awesome about you milling your own lumber! How do you plan to dry it?

A comment about your plywood. Make sure to use marine grade that meets BS 1088 standards. I assume that is what you are using. Just trying to save you some crying in the future... :wink:

Timber was all air dried. Not the ideal way to dry it but I have still been able to get usable timber out of it, just take a bit longer machining it straight/square. Or in the case of the battens, find pieces with just the right amount of twist. ;) The plywood is stamped BS1088 so fingers crossed the manufacturer actually followed that standard.

Thanks for that document, I’ve left the transom oversized for now. Once I’ve flipped the hull I might take it to the Suzuki dealer to confirm all the dimensions. The outboard has to be installed by them for warranty purposes so I’m probably best to check with them anyway.

Bit of a slow couple weeks. A little stuck on frame 4 at the moment. Using the double gusset method, based on 6in from the corner, there is a relatively small area to be glued on the base member compared to the side member. If I make the gusset much larger it will be too intrusive in the front cockpit. What do people think of using 3/4 ply gussets in place of the 1/4 but shaping them to fit the frames instead of the radius type in the plans?
