I'm just starting a Speedline 1:12 Tamar.
There appears to be no supporting skeg for the prop shafts external to the hull. Is this correct?
The Model Slipway 1:16 Tamar does have a skeg

Hi Ken
Have a look at philsrcmodels.co.uk

Hi Ken
It should be in your perspex parts...
Russ

All sorted
Thanks

Ken,
Just out of interest, where were they? I couldn't find mine either and gave up searching in the end. I made them out of ply and epoxy and had to guess at the size from the RNLI drawings.

Hi ChrisJ
Just been looking at Phil Locke's website and it looks as if he's had to fabricate a skeg for his 1/12th Tamar from two pieces of 5mm perspex.

Hi Chris
The skeg is made up of 4 pieces of perspex, cant remeber which sheet they were on but if dont have them you should ring Adrian at Speedline, im sure he will send them if they are missing....

Russ,
Are you talking about the "skeg" that is the extension of the keel? if so i agree with you.
I was talking about the skegs to support the prop shaft tubes.
Some modelers appear to have fabricated these, others appear to have just left them out

I had all the pieces for the midline keel extension. It was the those for between the propshafts and the hull I couldn't find.

Hi Ken,
Sorry you mean the A frames? I use the ones from Mobile Marine, good sturdy ones....

As you can see in this photo

and how the shaft is supported on the underside

Good morning and thanks for the effort to make a tamar life boat...i am also willing to make one from thermocola nd paper...so i am waiting for the pics and notes from you...nice...

Ken,
You are right in that the actual Tamar does have skegs rather than A brackets supporting the prop shafts. They are shown on the the RNLI plan sheet labelled "Docking Plan" that is in the set they sell.
I made mine from plywood, sheathed in epoxy and I took the dimensions from that sheet. I made them before setting the prop shafts in place, and used them along with the jig Adrian recomends to allign the shafts. I then glued them in place after the shafts had set.

I was watching this thread with interest because this is an area of the Tamar that has changed over time. The early ones had no visible support for the propshaft. I thought it odd too since practically everything has an A frame to support the shaft. The Tamar always was 'adventurous'.

I have also cast the inside of the shafts as well, to stop any movement as I am using brushless motors. Plastic card sides were removed when set.

Looks good Phil. There is an extra layer of GRP in that area to add strength too.
