HMS Blandford Project Main Support Page

I have been going through the list of materials and have come across a slight problem. The material list, for the 1:48 says the keel should be a piece that measures 1/4"' x 9/16" x 5 5/16". According to the drawings this should be 1/4" x 5/16" x 5 5/16". Is the 5/16" the proper measurement?
Also there appears to be a slight rise in the keel starting at frame 7 going through to 9, how does one achieve this, or is this what the new frame drawings have accounted for?

Thanks
Don
 
Don,
i will pass this info onto Mike. We will get back to you soon. Check back here for the answer.

Hi Don,
The dimensions for the keel including the rising wood is 1/4 x 3/8 x 5 5/16”, the false keel adds another 1/16” to the overall height of the keel assembly. The drawings take precedence over the estimated material list.
There is a 1/8” rise in the main deck from Frame 1 to Frame 9, all the frames will be trimmed to accommodate the rise. The keelson, thick stuff and deck clamps need to be installed before the frames are trimmed. There will be a drawing indicating the trim line included in Part 3 of the build.

As soon as I can get around to it, Mike has more drawings. It will be several days before I can get to this for Part 3. But, I see that most people are still working on frames, etc.

I am a few weeks behind everyone else on this build, so I have been going thru all of the plans to familiarize myself. I printed all of the frame sheets out along with the instructions and BOM. It is my hope that I don't get booted from this group build with the questions I have here :)

I am going to build the 1:32 scale version and printed out the build-board plans so that I could affix them to some plywood and cut them. But as I do with most projects, I first went thru and checked the plans with each other for consistency and accuracy. I printed everything on ledger paper (11 x 17) and found that they printed to scale. With the exception of the Blandford-Keel detail sheet (the sheet that has the isometric drawing of the keel end). The keel profile and plan are out of scale and in fact are larger than 1:32 scale. This sheet is important because it is the only one so far that illustrates the upward shift in the Keel notch.

As a result of my plan check I have several questions about the plans and I have looked thru the support page to see if they have been addressed previously, but did not see that they were.

FRAME PLANS (1:32 Scale Only)
1) Is the water line the same as the top surface of the build-board? And if so---the frame sheets measure the water line at 4-3/16", but the build-board plans measure it at 4-1/4". Which is correct?

KEEL DIMENSIONS (1:32 Scale Only)
2) Is the keel height including the false keel 9/16" or the keel without the false keel 9/16"? The plans (Build-board plans and Frame Sheets) when measured show the total height of keel and false keel as 9/16". The BOM shows the height of the keel as 9/16" and the false keel as 3/32". If you use the dimensions that are on the BOM, the total height would be 21/32" ? I need that clarified.

3) Is the length of the keel 8" as indicated on the BOM or is that just a rough length. As I read the Build-board plans, it appears that the keel, if finished flush with the aft face of frame #9 and the forward face of frame #1, it would be 7-3/4". Should I just cut the keel to the 8" length and trim it after the frames are all installed?

SPREADER BAR (1:32 Scale Only)
4) Is the notch at the top/center surface of each of the spreader bars important? And if so should I take care to insure that the notches all line up with each other at the centerline?

Sorry for the questions, but I was a draftsman in my younger days and I haven't shaken my routine when it comes to plan checking. I hope that I am not over-thinking this

Hi AP,
I will send this onward to Mike41 this evening. Thank you for this info. I am sure that Mike can clear up your questions. :) No, you will not get booted. We appreciate your feedback !

When we started the group build, we inadvertently issued some preliminary drawings and data sheets that had not been checked and appreciate your comments, all issues will be addressed, corrections will be made to the documents.

Frame Plans – The water line is correct at 4 3/16”, the top of the build board will be corrected to this dimension.

Keel Dimensions – the overall height of the keel is 5/8” including the false keel. The keel length of 8” is a rough dimension and should be trimmed after the frames are installed. (the 9/16” dimension was a carry-over from the 1:48 BOM)

Spreader Bar – If the center notches in the spreader bars are in line it will reduced the amount of sanding required to make the frames aligned on the interior and exterior. The spreader bar just helps the top of the frames stay in alignment, it is made from scrap wood and will be removed when the deck clamps and thick stuff is installed.

The quality of the drawings should be improving, I am building each section of the build and will include photos in my build log, posted with each new part of the project.

Mike, What about the dimensions of the keel in the 1:32 scale is the BOM and the drawings right I want to get materials to get started. THANKS Don
 
Don, you need to download the revised drawings and BOM
 
Hi Mike,
Is the link for the BOM still the same if not can you please send me any revised links to plans , instructions, and BOM.
 
I have the newer revised copies of the keel, build board and BOM that I will be uploading to site this afternoon.
Thank you all for your patience. Mike41 does the design and drawings and I create the links and download pages. It takes a little while since I am busy all around. Pleas check back on the support page as I will update the material shortly. I will send out PM when I am done.
Donnie
 
The revised sheets (per Mike) are ready for download (same place) just click on link again. You might need to refresh your Internet Browser (F5) just to make sure you get the revised sheets. I know that he BOM has "strike throughs" on the things Mike changed. And also the date of the document is also changed at the bottom to make sure you are looking at correct sheets.

All members of this Group Build should receive a PM on this situation as well and the link to page 1. The link is the same as it always has, I just included it in case some did not bookmark these pages. Just the material has changed - not the links !!!

Doc change:
Blandford Bill of Material
Blandford Build Board 1:32 Sht 2
Blandford Keel 1:32

There is an interesting article about Harold Hann by Dave Stevens posted on Navy Board Models, it shows the quality of modeling we would all like to do.

In 1/32 scale, the revised keel measurements are 5/8" rather than 9/16", but the false keel remains at 3/32". The total of the two is then 23/32". The revised plan drawing shows the keel to be still 9/16" and the total is 21/32" Both drawings are identical despite the difference noted in the BOM. I think this could be confusing, because in this case we need to build to the BOM not the plans. The date on the original plan for the keel is 9/8/17 and the revision is 10/29/17.
