Title: Canadian Corvette K338
Post by: ggeorge on December 07, 2010, 01:37:30 AM
Hi All,
  Glad to be back after a short brake from building and enjoying running my TID tug this summer. Ran great with no problems and now it
on the shelf until next spring. I started a new project a few weeks ago. This is a military subject. The Canadian Corvette K338,
HMCS Lindsay. She was named the town Lindsay which is only a few miles from here. I had a glass fiber hull which would have taken to
much to modify as the Lindsay was built in 1943 and was part of the Increased Endurance Program. This gave her an increased flair and sheer in the bow. Also the stern on the Lindsay is squared off. So I have started by making my own hull and here are a few photos as it stands so far. I will keep you updated as I progress. Winter is here and my shop is the nice way to spend the cold days.

Hi Again.
  Here are a few more photos as the hull as I progress. The scale is 1/4in.=1ft. which will make a the model 49in. at the water line and 52. in. overall. I preferr to work in a larger scale but it would make the corvett to large.

Work plods along. I have managed to locate the battery and motor and the rudder servol. I am ready to epoxy the upper deck on.
My TID tug has great access when I lift off the super structure but the corvette will not be as good but I think I will have be able to access ill the equipment, time will tell.

Hi All,
  Here are a few more photos as I progress. As far as the question regarding the brass. I do not antisipate as much brass as was used on the TID. but there will be some brass work.
  All the best to everyone over the holidays And a very merry Christmes to all.

Hello George, another superb build on the way no doubt, must admit I really enjoy looking around your cracking workshop as well, and just love the phone!
            would you mind helping to try and educate a late starter re your motor and set up?  i.e. what type is it, how did you chose what would be right for the model, it's obviously geared and going to be belt driven I assume, why not direct drive? etc. etc. hope you'll excuse my many questions but I'm quite baffled at the array of motors available and technically quite ignorant with electronics - but I do manage to learn a little along the way.

              Looking forward to the rest of the masterpiece, kind regards, Tony.   :-))

Hi Tony,
 Sorry I did not get back to you sooner but the holidays have been very buisy. I did manage to get into the shop for a few hours and here are a few photos as the corvette build continues.Motors for model boats are a major topic in itself.  I use a variety of moters. In the TID I have a power seat moter which is 12v high torque and low RPM. and direct drive. The moter I am using in my corvette is a 6v Hectoperm.This is a moter I have had for a while and it will suit the corvette. I am using a belt drive because the prop shaft is to low to line up with the moter shaft.I have used tooth belt drives in the past and have worked well and are quiet.

Hi All,
 Progress plods along. I have been busy with other things and have not spent much tine in my shop lately. But I have got a little work don on the rear gun platform and light platform. We are having our normal winter lots of snow and cold -22c last night. I am ready for a brake. I will have to wait until April as we are going to Florida for that month. As I get more work don on K338 I Will post them.

Hi All,
  It has been a long time but glade to be back. I have been busy running my boats, a Little bit of traveling  down to Florida for a month and up to Labrador and the Trans Labrador Hy way  and enjoying my car I built when the weather is good. I did find some time to build a springer tug. I am back on my k338 corvette and have finished plating it with 10 tho. styrene, which worked quite well. Working on the fittings and will keep posted as I continue.

Hi Gerry - I am following the plating & the posting string with interest...... O0

1.........0.010" styrene sheet plates....what glue did you use to provide a water proof bond to the wooden & semi filled planked hull?
2.........what is the purpose of the thin green tape strip on the hull?

Derek
Title: Re: Canadian Corvette K338
Post by: ggeorge on February 10, 2012, 05:22:35 PM
Hi Derek,
  The hull was covered with fiberglass before I added the styrene. The styrene plate was sanded with 150 grit paper and ca thick was spread over this sanded area and then the styrene plate was placed in the correct location. I have used this method in the past and has worked well for me. I have never had any problem with water with this method. The green tape is just used to scribe a strait line on the location of the plating. I take points off the drawings and mark these points on the hull and then I use the tape to join these points and scribe a pencil line along the tale which now will give me the plating location along the hull.

Hi All,
  The cat is Mr.Tibs and he is more a pain in the but than a help. The only tool and die he may get involved is get his tail caught in my lath as he is always around were I am working. If that happins I will send photos.
And Tony feel free to correct any errors as I sent two photos and then resent them by mistake. Also the phone works but is only a reproduction. I am just about finished the 4in. gun and may start the hedgehog next.

Hullo George....I am little intrigued with the gun mounting..........in image 24 & 26 we see what I believe are two sights on either side of the barrel

On the PORT side we see the hand wheel & shaft going down to the pinion for elevation of the radiused rack........is this simply repeated on the STDB side....or is this side for training [slewing]?

Many years ago I spent considerable time involved with 5"/54 calliber FMC guns on our HMA vessels.......but the elevation & train functions were electro-hydraulic  :-))

I look forward to continued build of the mounting & the vessel....Derek

Post by: ggeorge on February 25, 2012, 12:24:00 AM
Hi Derek,
 What I am going on are drawings in a book on navel weapons of WW II and what I can find on the Internet and I cannot get much detail of the starboard side but the drawings seem to show a wheel and the shaft going down so at this point I am open to any suggestions as changes can still be made at this point.
Title: Re: Canadian Corvette K338
Post by: derekwarner on February 25, 2012, 01:17:19 AM
George......yes I see the STDB side view now.........with the hand wheel & vertical down shaft

I think it would it would be fair to assume that this STDB wheel would have had an identical drive hand held peg to the elevation wheel

The down shaft would have employed a similar set of 90 degree bevel gearbox/s & meshed up with quadrent rack ring of the train gearing

I also see the train stops in the pedestal just above deck level....from the positioning it appears that the mounting had 180 degrees of train....MINUS the physical length of the center stop block

The fixed stop block would have contained a spring buffer on either side......the moving stop blocks were an earlier method of achieving pointing & non pointing zones [which prevented a silly sailor from firing at the vessel bridge {-)] ......Derek

Wow spectacular work, about the hedgehogs my Dad had talked about hitting their own mast with them, I believe it was when he was on the HMCS Ste-Therese.
How would that have worked? Were they on the back of the ship firing forward as well? Were they supposed to lower the mast?
Thanks and again you do amazing work.

As Bryan Young recently said in another thread.........

Design was just an evolution with the British Admiralty ....the plans are layed out to be built.....but by the time the building progresses....then so has the design requirement changed

This was also certainly the case with weapons systems.........from the different images...it is apparent that the Flower Class vessels had quite a number of 4"gun mounting variants......

It is possible that parts have been removed, either by the Trustees or collectors.  <*<
I am sure you must enjoy making parts in brass, as I do.   It takes much longer but is very satisfying.  O0
As you say Norseman, it's a pity it has to be painted.   Maybe the next model should be one where all the brass was polished.

 I got part way through building the 2 pdr gun and it just did not look right even with the drawings that state a scale I am using. So after taking measurments I find the gun was too small.
So into my scrap pile. Here are a couple of photos of the new build so far.

Give brass a go.
It's not so hard to work.   I use a jewellers saw with blades from a jewellers suppliers that are very fine.   Size '0' to '2'   Buy plenty as they break quite easily.   Needle files, fine 6" file.
A good soldering iron is essential, 40 watt is usually enough.   25 watt ones for fine detail, but not essential.   I prefer to have a chisel point on one end of the 'bit' and a point on the other.   Just make sure that the iron has cooled before changing ends.   Ouch!!!  <:(
Paste flux on both surfaces and make sure they are very clean.  O0
Not to much solder or you will make blobs as it cools to rapidly.
Nice to have a lathe but I use a big electric drill in the vice for turning using a selection of files for shapping.   Don't buy K&S rod it is to "hard" to turn.   Elecrtical wholesalers can supply some sizes that are used for 'Earths' which I have found to be much "Softer"

Here is a note from ggeorge on his chosen soldering/build accessories.......I agree with BrianB6.........give brass a go.....Derek

Hi Derek,
 I hope the photo will answer your question on the products I use. To sounder a joint I use the liquid flux and brush it on and then I will cut off a small piece of solder and place it on the joint. Now using a small butane torch I will heat the joint away from were I placed the solder and now the melted solder will flow towards the hotter area. If I have other solder joints close by that I am concerned of melting the solder I will soak a small piece of paper towel and place it on that joint. This may not be the best and easiest method of soldering brass but it works well for me. Enjoy your summer down under as we are having our typical Canadian winter.

Hi ggeorge

Just wondering how the build is progressing?
... Especially any new brass work  :}

Yes George....where are you?.......I have just realised the significance of your 1948 half penny piece {-)  ..... I managed to find  an Australian 1954 half penny for my wife [in a curio store in Hahndorf ....Adelaide hills].......but have never found a 1949 minted piece for myself.......... >>:-( <*< ....Derek

Hi Derek,
 I hope the photo will answer your question on the products I use.

Hi
how are you brass-workers drilling 0.3 or 0.5mm holes in brass? I buy non-branded 6-8 hobby drill sets from hobby shops. The set ranges from .3mm to 2mm drills in .5 increments. If I try a tiny drill on brass, if it dosn't snap first, it blunts fairly quickly.

Am I buying cheap drills and a more expensive, better brand set will drill these holes? Or is it asking too much of what are one 'land'/'flute' drill bits?

Hi Pondweed........
I am far from a competent driller of small diameter holes in brass....but am old enough to know a few tricks
Look up a table for surface cutting speed for brass  %) ...you will probably find a calculation for conversion to RPM per diameter
You may well find the recommended RPM for a 0.5mm diameter HSS twist drill is 20,000 RPM  O0
You must use a pedestal drill [or a small die grinder with collets......but this MUST be aligned in a vertical  press with some form of accurate feed]
Most hobby pedestal drill as fitted chucks go down to say 1.0 mm....so a precision keyless chuck may be required
The work must be adequately supported....with accurately placed centre pop marking in the piece being drilled.........
0.3mm diameter is a very small hole......the smallest holes I have drilled in brass is 0.68mm diameter or 0.027".......& I find these difficult & testing....these are conventional two flute 115 degree included angle drills
I do have experience with single fluted "rifling" drills for deep hole drillings 8,000 mm deep .....but these diameters are 20 mm +.....I have ZERO of knowledge of single fluted fractional mm HSS drill bits......
Now in theory.......brass does not need a cutting compound, however ROCOL  general purpose cutting paste will assist  :-))  .....good luck.......Derek

Hi Derek
Your .68mm drill looks to have be single land/flute. No? Appreciate the good, sensible advice. But this is my problem with brass or other metals, mention of pillar drills along with all the other hardware needed to cut, drill and file metal and you're into light-engineering territory whereas I need to do this on a kitchen table. I know some guys fix their motorbikes in the front lounge but this ain't one of those places. :-)

But I'd be interested in others experiences in drilling sub 1.0 mm holes.

P.S. Just mentioning this so we all use the same terminology about drill-bits othrwise this could become messy. :-) When I looked at drill bit terminology last night, the 'flute' or 'flutes' are the grooves up a drill-bit that remove the spoil, the 'land' was the high or full diameter bit of drill that spirals to the point.

Cheers

Pondweed, rather than go the high speed drill route you could also go via a pin drill by hand - so far I have managed to drill down to .45mm in a 1mm brass tube,
I put the drill bit into the pin drill until only about 1/8 inch is showing and put a very small flat on the brass tube with a jewellers file and if you are
careful( and lucky) the)drill bit does not slip ( and break) but I buy my drill bits in bags of 10 as they don't tend to last long

Remember reading a modelling tip that if you put tape, clear tape,masking tape, over where you are drilling it will stop the bit wandering, also start with a slow speed then increase once the point has "cut' the surface.
 
As in all instances a sharp tools cut easier.

I had a go in brass recently, as i wanted to replace the plastic fantastics version, drilling small holes to pass thread through solid rod, the other holes were through brass tube to pass other tubes through. I enjoyed the build to a certain point - but as a first time try at this, bricked it. The results turned out fine at a distance - especially painted, I used what I had, a 40w soldering iron, a dremel style multi tool and a bosch hand held 14v drill, holding the 1mm drill and above was difficult as it would sometimes jam as the drill became more blunt, soldering was a laugh, the solder I had was some plumbers solder - quite thick but it worked out well with the flux I had bought from Maplins (then found the flux later that I bought for the plumbers solder).
 
I am in awe at the quality of the craftmanship of george - makes me want to get my old corvette out again and refit her.

Does anybody know how George is getting on with this model - If it is anything like the Tid Tug he finished a
few years back it will be stunning

He's slowed down for a bit. I think he has a bit more done than when he lasted posted, but he's taken a bit of time off completing it and doing one or two other projects.

This is an amazing build. Your brass work is taking my breath away.
I especially like your Hedgehog. I was pondering how to approach one for my icebreaker. Now I see how.
Many Thanks

Hello George, I joined here searching Flower Class Corvette and saw your thread. I am blown away by your craftsmanship. You are very talented individual with some brass and soldering gun. I hope to try this teach myself next summer as i need to start on my FCC 1/72 kit by revell. Well, it seems there has been number of years since your last update, so hope to see what else you might have done your lady. Thank you for sharing your work.  ok2
