Hi,

Any ideas on how to simulate rivets please?

Thanks in advance

Hi,
To simulate rivets on a hull or superstructure there is 2 methods
I Know of

1) PVA Glue applied in dots using a syringe and needle or a cocktail stick

2) small round headed pins, drill a hole and glue them in

Both methods are very time consuming hope this helps

You cvan get them from Precision Controlls, but if you want a big bag of them I got one.
I couldnt face all that drilling!!!

There is a third way, if you are applying plating. You get (or make) a thing called a pounce wheel, which is like a clock gear on the end of a stick, then run this along the back of the plating. It makes a row of raised dots on the front. I've tried it, without much success, I'm afraid, but it is supposed to work.

Slaters Plastikard also do sheets of rivet strips, never tried them as I always use dressmakers pins or PVA using a syringe.
Slaters also do all your treadplate requirements

I can recommend RickF`s tip- and have lead it a bit further. As this wheel (which is used by tailors) might be too wide I have bought some stainless-steel gears and pressed them on a rod- then rounded the teeth on a lathe and made such a stick on my own where I can change the gears for "riveting" about dia and distance for the wanted scale.

Heard the dress makers wheel works on thin plasticard plate as mentioned above, never tried it though. Tell you what DOESN'T WORK, though. Scratch built 1:24 Will Everard, thin ply planking then covered that with thin ply scale plating to help waterproofing. Secured each plate by drilling hundreds of holes through plate and planking, then tapping in cocktail sticks and gluing same (one stick cut into four 'rivets') The idea being when dry I would sand down and leave slightly raised rivets. What in fact happened - sanded down and cocktail stick/rivets totally disappeared !! My original theory was that the sticks were hard wood (bamboo I thought) Fact was sticks very soft   >:( >:( Pointless exercise

I have got some nice brass portholes. What can I use for rivets, appart from the brass pins.

Any suggestions?

I am currently making a Mountfleet Ben Ain and the first rivet detail I tried was on the fo'c'sle bulkhead.

I particularly wanted to match the bulwark butt straps that were supplied with the kit so I drilled and fit cut down dressmaking pins.  This was very effective but extreemly time consuming.

For the hull I wasn't about to start drilling hundreds of holes to fit pins so I set up a test piece and tried a number of differrent glues, applied as a small blob.  Most of them went flat when dried but the one that remained proud the best was cyano gel.  I did find that if I applied it directly to the fibre glass hull it was absorbed and once again went flat but if I applied a coat of grey primer first (Halfords best) then the gel formed a much more appropriate blob.

I therefore applied a coat of primer to the whole hull and commenced adding the rivet detail to the plate detail already there.  I tried to emulate correct procedures used at the time within the constraints of the plating arrangement already there.  The entire hull took about eight tubes of cyano gel and about a week to do, working a few hours each day.  I lost the will to live more than once but the effect at the end of the day was well worth it.  The hull looks ten times better than it did without the rivets.

Next when it came time to add some rivets to the wheelhouse I couldn't see the point in drilling and adding pins again so I went for the cyano method for the rivets there.

I think one of the most significant aspects of it is to try to carefully consider where joints would be in plating.  Plates at the time of my coaster would usually come as stock 8' x 4' sheets and would usually be joined adjacent to a curved plate.  Scribe the plate lines accordingly and add rivets to either side of the joint.

As for port holes I added rivet blobs around the exterior of the brass tube set into the hull.

Finally it would be common, although not guarranteed, to use flush rivets for decking to prevent tripping so for the decks I used the supplied cartridge paper to create the deck plates.  When I had cut the plate to size I went around the edge very gently with a sharpened peice of brass tube and created the flush rivet detail.  It took a while to get the pressure of the hammer exactly right as not enough and I didn't get the impression but too much and I cut a hole!!  When I had done the edge I glued them down in an appropriate pattern.  You can't see the flush rivets much but when the deck is painted and a dirty wash applied I am hoping the detail will stand out very effectively.

I hope this generates some ideas for you.

Thanks for the comments guys.  Here are a couple of shots of the steam plant going together as well as a couple of her sea trials.

I have also written a build thread for another forum here:

hey Bunker,

I tried the cyano gel suggestion on a test peice,- works great.

One q though, how do you get consistency in the size of the blob? I am using the dispenser that came on the bottle.

A word of warning if using cyano for an hour or so a day. Make sure you wear a mask and \ or a well ventilated room. Cyano fumes are not good for you.

For rivets I use the nails for doll house hinges.

Thanks,

They came from my LHS in the 1/12'th scale dollhouse stuff. The head size came out perfect for my 1/32'nd scale C.S.S. Albemarle ironclad, all 5000 of them.

Another plan is to cut card [like postcard] into plate sized pieces,

and after robbing your grannys westminster chimes, inside are the gearwheels various pitches, run a straight edge along your chosen rivet line (back to front of course) double rows offset...............then paste on to your boat, you even get sliide tiz a piece of pizza.

MikeK,

Just revisited this thread and realised that you mentioned plating "Will Everard". Do you have any details on the plating of a steel barge? I'd be very grateful if you could point me in the right direction.

Hi Rick,
Try www.thamesbarge.org.uk  or on Yahoo groups AMBO Association of Model Barge Owners. If you Google Thames Barge Portlight it should show pictures of the rivited hull. The last time I spotted her she was at Maldon in a dull pink colour awaiting restoration.

Hope this helps
