Thanks for that Michael........I'll take that on board...

Hi Andy the conduit I used was sufficient. One thing I would suggest is that you use a feeder wire leaving it in the tube when you need to pull another wire through, this is a length of wire twice the length of the tubes which you attach your new wire to it in the mid position then pull your additional wire through. Remember the more wires you get in the tube the harder it is to feed a new wire through.

Hi Michael, I'm starting the next stage now, the bulkhead formers. As already mentioned, I'm planning to use some flexible plastic tube I have for the wiring as in your blog. So having removed the formers from the sheet and de-nibbed them, I'm planning to drill the 10mm holes. I just thought before I did, I would check with you if the amount of conduit you did worked out the right amount, could you have done with less or more? Thanks Andy

Hi Michael, yes I think I've done it correctly now.
I've attached all the keel pieces, including the laminated strengtheners and tomorrow I hope to move onto the next stage, the bulkhead formers.

I have some 8mm (hole) plastic pipe, which I hope I can use for the underneath wires, instead of making your custom made pipes! I'll update the blog at the weekend.
Thanks again for your help!

Hi Andy Its Michael but I answer to both, I hope following the plan of the keel construction solves your issue of angle
as for the prop shaft I used an 8mm tube with a 4mm shaft I found a better selection of props at M4 thread

Sorry, firstly I'm not sure if you are a Mike or a Michael, I've seen both used on the forums.

Thanks for your post, which I have only just seen as I've been busy typing one and trying to attach pictures (not very successfully) and our posts have crossed......
I have been consulting your blog and have scanned through it, but obviously missed that. Probably because I've been concentrating on the first steps.
I think my result is similar to your advice, if a little long winded and unnecessarily complicated.

Thanks again for your advice, I'm sure I'll be askin for some more soon!

I've worked on this most of the afternoon, unfortunately I had no luck finding an answer on YouTube or elsewhere.
I eventually worked out, that by mocking up the 'hole area' of the box base with a spare piece of ply, that 3x 8mm close drilled holes and careful filing/sanding the angled ends, makes the right size prop shaft hole.....probably.
By placing the 'proxy' ply on the plan and putting a pencil through the hole, it appears to be the correct size and angle.
My son, who makes models (but not boats) thinks the prop shaft would probably be a 9inch/228mm M4 ?
I'll have a go at it tomorrow, so that I can continue fixing the keel.

Andy this is an extract from my blog provided you follow the keel build instructions it leave a square hole large enough to accommodate the shaft, just re-read the blog I'm sure it will clear your concern.

"I forgot to publish this operation at the correct build point so here it is slightly behind. The angle of the prop shaft is taken from the drawing so it can be transferred to the brass shaft whilst in situ; the hole created by the build leaves a square hole large enough to allow some vertical and lateral movement so I can now position the shaft with the aid of the angle gauge along the centre line and set using epoxy. The underwater part of the prop has a supporting ply quadrant which will be epoxied at the same time, I use some light wedges to position the shaft and hold it whilst the epoxy sets".
