Mike:
I have been meaning to talk to you.
I have some pictures of a rove punch from an English Gentleman. The rove pictures are really good and are on my web site. But I am still a bit stumped as how the end is finished. Is it flat? And also have you any ideas on how to make it without a lathe. I can get to a lathe but it is very hard.
Laurence (an English Gentleman) gave me the following dimensions for a rove punch:
Internal diameter = 0.244 inches which is 6.2 mm
External diameter at tip = 0.346 inches which is 8.8mm which implies a wall thickness of 8.8 - 6.2 divided by 2 = 1.3 mm (1/19th inch). This seems to be very small.
External diameter of roves = 0.397 inches which is 10 mm.
Diameter of copper nails = 0.105 inches which is 2.7 mm.
I will measure my nails and roves when I get home and report the findings tonight.
Mike: Your thoughts would be appreciated on how to make the little blighter.
I have also had success, well I am part way there, in splitting a plank into 3/8 planks from a 4 quarter plank. I built a jig to hold the plank (which I had splined-although I now think this was not a good idea) - and I used a hand electric saw to take a cut on the top and bottom. The plank is 7.5 inches and the saw will do 2.5 inches each cut. I am slowly (being a very operative word) sawing the middle out with a hand saw. I thought I would kill the 15 amp electric saw as we are only 120 volts. I will have to bring my good one back from Australia and get the garage wired for 220 Volts.
So thank you to J Larrabee, your method took some careful prays before I tried it, but it worked (so far).
My original jig stinks. I am looking to make a much better one to speed up the process.
Also has anyone got the plans for a carpenters bench/stool like you see in the Lee Valley Catalogue. These benches are designed to easily use a spoke shave and plane on lengths of timber.
Money runs out very quickly when boating is a hobby.
I was studying the 15 foot Thames Lug boat in the Knight book on Small Boat Sailing (Figure 50), I will scan Figure 50 and put it on the web, but that little beauty of a boat looks an awful lot like Scarab. Much more so than Amazon or the real Swallow pictures with AR afloat.
Scarab also has one of the features of Knights mast that had always intriuged me - it is not written about in SA or SD but seems to me to clearly show up in PM, I would bet a cold Coniston Pint from the Forlorn Chook that he took some ideas for Scarab from Knights words and the picture.
I have also learnt how to find the big dipper and the north star at a conference.
Anyway goto go work.
