  1. May I be so bold as to ask one more question regarding mast dimensions if I may. I see from the AOTS Diana was launched on march the 3 1794. I also notice that 1794 is a fairly important year for the subsequent change in mast dimensions and how to work them out. I f there is a change of dimensions in this year I am assuming if the ship is launched without masts and perhaps not made yet. In this case would we take the formula given for before 1794 or for after that year and after. Once again I am not sure if this would be much different other than a slight difference in the diameters. So really just a matter of interest and perhaps the diameters increased due to the increase in the amount of sail carried as time progressed. Just a thought so could be wrong. Best regards Dave
  2. Phew I am glad I got that one sorted. So for my masting and spars I think I am pretty well sorted then. However apart from the breeching rope and the gun tackle I think I will leave the rest of the rigging for another day. But a huge thanks for walking me through this. Best regards Dave
  3. My working out is different than the spread sheet. for a main mast length of 92.5 ft . According to Steel the diameter is 9/10 th an inch for every 3 ft for 1794 gives me 30.8x9/10=27.75" change to metric x 25.4 and divide by 64 =11.01mm Fore mast is 0.9 the length of the main mast after 1773= 83.25 ft /3ft = 27.25 x 9/10 = 24.975" x 25.4 then divide by 64 = 9.91mm. According to the book AOTS Diana they also have the main mast at 11.01mm but the fore mast diameter at 9.77mm . So another discrepancy. Any idea where I am going wrong???
  4. Having looked more closely at the results of the masting sizes on Danny's masting sheet and looking at the diameter of both the main mast and the fore mast as the same 11.2mm on the model. I believe this to be incorrect but I could be wrong. I have taken my calculations from Lees book'The masting and rigging of English ships of War ' and as the lower fore mast is shorter than the main mast by 0.9 x the main mast = the fore mast then I assumed that as the diameter of the mast is calculated for 1" for every 3 ft of masting , then if the fore mast is shorter than the main mast then the diameter must be smaller. There is some ambiguity concerning Lees wording on this which perhaps I may have got wrong . In the Proportionate Diameters of the Mast section in Lees book FORE equates to 'The same proportions as given for the Main' My take on this would be for the same proportions as to the length of the fore mast and not main mast. I Hope I am making sense and wonder if it is possible to change the formulae in the spread sheet without too much trouble but beginning to think Allan is correct and we are just better off just working all this out for ourselves. There is however the possibility that it might be another incompatibility issue. However it is my hope to borrow a windows office 123 lap top installed and try this out for my own curiosity.Thanks again for all your help and patience. Best regards Dave
  5. Thank you Andrew for kind words. Hopefully the heights should be fine. If not I might have to add a shim or remove a sliver of material from quoins but that could be tricky. Perhaps I could take a bit off the front or the back of the trucks but that might look a bit odd with a flat tyre. I have a couple of spare trucks if there is only an odd one or two. So could make another if all else fails but really hoping it works out OK.
  6. Few! Almost completed adding the brass fitting to the cannon but cannot make up the rigging for the cannon as I am still waiting for the breeching rope from 'Ropes of scale' I had some difficulty fitting the capsquare bolt to the 18lb gun carriages as these were tiny, so ended up drilling out the capsquare on my Proxxon milling m/c and using blackened brass wire. I also ended up removing one of the eye bolts on each side as I realised that it was easier to attach the 3mm brass rings to the eye bolt before attaching to the carriage. Whilst waiting for the breeching ropes I have a few small jobs which need attending to mainly adding the Cavel blocks and securing the brass lings to the or ports. I can also drill the holes for the breeching rope gun tackle eye bolts . This should be enough to be getting on with but will be taking a little break during the Easter period. Another mistake . I should not of glued the Quoins into position until I checked the hieght of the gun barrels in the ports but hopefully they are fairly central . The of the gun barrels look to be all a similar height so fingers crossed they look ok I also forgot to mention that I ended up fitting the Bloomfield cannon , although I am still uncerain if these were actually fitted to the Diana. I quite like the look of them, although I did not attempt to fit the very tiny gun lock or the chain for the cap ssquare key.
  7. Lovely area and coastline. It's a long time since I was up that way but never noticed the plaque. Hope you get some decent weather. Enjoy your Easter Break Andrew. You deserve it.
  8. Thank you Thukydides for another table /list . I think thats what I was trying to say that the carriages would move further back and causes problems for them when first fitted.Perhaps thats why there design of the carriages were different too. Am correct in thinking the different amounts of powder were for Proof (testing) In battle ( service) Saluting someone of another vessel perhaps but could not work out what sealing is? Thank you again for sharing your valued research , you definitely like to get an understanding of what really might be going on all that time ago. Thanks for your likes on my Diana log too.
  9. Would a lighter gun and possibly carriage not move further back for the same size weight of shot and the the same amount of charge. Just wonder why they had a few problems when first used. The length of ropes do seem a bit shorter than for the same calibre ordI inary cannon but could be wrong. Thukydides thank you for the rope sizes much appreciated . It was my plan to use the 5.5" for the cannonade guns as ell as for the 18lbs as give in Allan's suppled data and see how it looks . Best regards Dave
  10. Thank you for your thoughts which are much appreciated. I take my hat off to you sir for your thirst for knowledge and look forward to hearing if you come up with anything that might give a better indications . Best regards Dave
  11. This is turning out to be a very indepth and interesting discussion and although I am having difficulty understanding the tables( probably due to the writing and mpoor eye sight) I however thank you greatly for posting them and for your time and patience in helping me.Due to yet not being able to determine the exact dimenions of the breeching ropes for cannonades and, interestingly I see on Allans supplied 'Instruction of gunnery' table it states on the bottom of the table ' That the length of the cable is left to the the discression of the gunner. It will be interesting where this discussion leads and I have some time before I will need to make the choice but have orderd up rope for 32lb guns and compair this with the 18lb guns and see what the differnce looks like at a scale of 1:64. Thank you all for the input on this thread and I am looking forwaed to see how far it goes and if it is ever actually resolved or infact what other people have done with their cannonade breeching ropes.
  12. Thank you Bob and Allan for your valued replies Bob, I was beginning to think that would be the case but it at lease I got the mast sizes from the program which seem to ceheck out ok. Looks like I will have to dig out an old windows lap top and see if I can get it going. It worked fine as long as it was still plugged into the mains electrical supply. Unfortunatetly it is quite old and probably wont run any programs these days but who knows. Allan thank you for letting me know the data is incorrect for between the dates you have mentioned. For the record I have a copy of James Lees book so will be able to work out the mast and rigging sizes from Lees instruction and least I will know I am correct for the date of the Diana was built.1794. Best regards Dave
  13. Allan thank you again for the above fore mentioned rope sizes. I am currently combining a list of different size ropes which I will need in the near future and require them to be ordered, thanks to you I am almost there. When ordering Breeching rope for Cannonade the dificulty is whe using bore of caliber . I am not sure if when firing the Cannonade whether of not the recoil would be less or more as the canonade is lighter but the shiot is heavier. I would like to know your thoughts or any one elses thoughts for that matter . Also Allan if I could ask you another favour, perhaps you know of another chart listing the size of breeching ropes. I am assuming the tackle would be similar to a normal 32lb cannon but I could be wrong. i must thank you again Allan for your time and patience.Best regards Dave
  14. Thank you for your valued imput and for the great spreadsheet by Danny Vadas, which at first had apeared to work fine. There was no warning message but I did have to transfer it over to google speadsheet called sheets. Anyway all seemedto be fine and the data for the mast came up ok but I was unable to use the buttons on the front of the sheet and had to use the tabs along the bottom. All great and the main mast diameter calc came up 11.2mm . So all good. I then went to the standing rigging using the tab along the bottom marked standing. Again all calcs came up for the Bowsprit and I assumed these would be correct, why wouldn,t they be as the mast dimenstions were fine.I have tried the button on the front marked 'Next Yard' and nothing happens as non of the buttons on the front apear to work. I am ony able to navgate the spreadsheet using the tabs along the bottom, even when I click on the tab list (the arrow at the side of the tab)I can,t see anything to move me to another mast or yard.It is the same with the running tigging tab too. Once again I think there are issues running this type of spreadsheets on google sheets and I might need to use a Windows excel spereadsheet to work. I hope I am wrong, as my eyes lit up when I saw the mast sizes for the model in metric are correct. I apologise for giving you the incorrect file .I have now attached the correct file but unsre if you can see it.I do like That Danny Vadas spread sheet as it looks a very profession job. I am prepaired to use the Microsoft excel spreadsheet if it will run on a Chromebook and I am prepared to pay a fee if this is the only way forward. I appreciate your help and for your time and patience but I could be wrong ( hopefully I am not) but I am beginning to think there are compatibility issues at play. Period Ship Scale Tables (1).xlsx
  15. I have now started to consider the rigging to use for the guns and their aopropriate diameters. The popular choices used include the synthetic ropes made by Ropes of scale. The diameters of the ropes were supplied by Allen . Here is the link for the circumference of the Breeching ropes and for our 18lb guns is 5.5 " = 0.7mm. and according to Lees book gun tackles for 5th and 6th rates is generally 2" which equals 0.25mm There is also the length of the breeching rope to consider and again another great chart from Allan We can see from the above chart for a 4th rate ship with 18lb guns the Breeching rope would be 27 ft which equates to 129mm . As discussed with Allan the difficulty is this ring to ring or does it include the half hitch knots and seizing at the ends. But this will give me a good idea as to how much rope I will require for the Breech ropes and have decided to use the synthetic rope supplied by 'Ropes of Scale'. I would also like to thank Andrew Johnson for a very good link which I found very interesting regarding the position of the breeching ropes and their eyebolts on the inside of the bulwarks. It is shown in here ,there are in fact two eye bolts on each side .2 of the eye bolts I think are for running out the gun and 2 are swinging the barrel fore and aft. There are also two rings attached to eyebolts for the Breech ropes .All good stuff. I have also been looking into ordering some of the ropes I would need for the 9Lbs guns and the Canonades to try and save on the postage costs, so once again I will use the combination of the above charts together with Lees book ' The masting and rigging of English ships of war' The Breechings for the 9Lb cannon from the above charts have a diameter of 4.5" and a length f 25ft which is 0.568mm and 119 mm respectively. Looks like a lot of rope for the Cannon alone. Length chart (1).xlsx
