Title: wee nip modifications !
Post by: triumphjon on July 23, 2010, 11:52:27 PM
ive bought the kit of pre cut wood , downloaded the plans and started the biuld , instead of laminating THREE  peices of 1/8 lite ply together ive used the centre core & biult up the profile useing fibreglass matt & resin . ive thought of moulding the rudder & centre keel for future spares if theres enough interest ?

We have a Wee Nip Meet every month and the record so far is 18 Nips racing against each other.
It`s becoming more and more popular around the West of Scotland clubs :-))
It`s a cracking little boat to build and sail,and I`m sure you`ll have great fun with her.
I`ll ask at the club tomorrow if there is any interest in the parts :-))

Anybody south of the border built one ? :}

im possibly as far south as you could be , im in portsmouth , hampshire ! 1 nip is in the state of biult hull , the keel & rudder have been coated in grp matt and resin & im about to start making a mould of it all ! ive decided that as i want three or four of them for our family use they would be more robust in grp !

I looked at the Wee Nip... but the hull construction put me off

ive used the traplet kit of wood parts as a basis , but i must admit it was a pig to glue together as there are no bulkheads ! however as i origanally wanted a few of them ive been looking into useing the one ive made to make a mould for a grp one instead ? pm if your interested . jon

I'm building a wood kit for a friend.The biggest problem I have is all the laser cut edges are covered in soot.

The plan is not accurate,the side view is slightly bigger than the plan view... I had to make a new transom as the supplied part is too small on the deck edge.

Well after a bit of a struggle, I have got the Hull together it's not as easy as it looks in the Dvd :((.... I hate bending lite ply...

The first thing that threw me was the amount of curvature that is induced across the deck, when you pull the bottom of the sides into fit the the hull bottom, but I looked at the footage on the Dvd and it seem to be normal...

I am using a 8mm carbon tube for a mast...How much clearance does there have to be in order for the mast to swing properly? The mast has several holes to adjust it's position realistically which ones are used, and does the mast have to be vertical? Am I going to have to enlarge the holes at the base the mast so it can be angled back?

sorry ive been off line for the last week , i built mine with out the plan set on paper as its a download to my computer ! i didnt have the dvd either ! but mine is now on the water . i made my gooseneck from a lump of scrap pine , drilled as per the mast/sail plan pic , my girlfreind has sewn a sail from ripstop nylon ( i supplied her with ) which was made to fit around the mast and boom , my first attempt was too steep , so a second gooseneck was fabricated , im using a plastic food pot for my rx/ battery thats in the deck between the keel box and the hull side which stands approx 19 mm from the deck , the boom passes the pot at 22mm from the deck at its closest point and tapers up to 82mm at its highest point . following advise from the glasgow & richmond club they recomend just using the central hole to position the mast , ive then blanked the other five off to prevent water ingress . this has so far been sucsessful !

triumphjon, I have still got to make my goose neck..I'm thinking of building mine out of  8mm ID carbon tube and some glass fibre PCB board to support the boom.

My sail will be 50micron drafting film... Im looking at using some form of pot/battery holder to save removing the deck patch in order to charge the battery.

What did you make the bow bumper out of ? Did you make the keel bulb asper plan

Post by: triumphjon on November 19, 2010, 12:32:03 AM
my radio pot is a small food storage pot from poundland ( set of 3 or 4 ) 50mm deep 90mm outer diameter with a screw top lid , ive craved the goose neck from a section of pine , use a slideing fit over the mast as it needs to rotate freely & a snug fit for the boom . as for the bow bumper ive not got one ! ive no plans to be racing as i cant be arsed with the arguments that are a commonplace with the racing folks ! the lead bulb i made by using sheet , i shaped the first peice into a wooden mould then heated more lead up & melted it into what i had already , repeated twice for the two halves , drilled them both through the keel fin then bolted the whole thing together with a couple of stainless steel bolts . it was then smoothed down & any imperfections filled with resin . my mast is a length of 8mm od aluminium tube cut to size ( 3.50 from b&q , if making both the mast & boom you will need two lengths ) i used a peice of dowel for my boom instead as it was in my scrap box !

Post by: Dekan on November 19, 2010, 02:41:06 PM
My mast will be 8mm OD CF tube with 5mm OD CF tube for the boom...I'm not sure where I would get stainless steel nuts and bolts from..... I will have to look in B&Q and check out their ali tubing..What department is it in?
Title: Re: wee nip modifications !
Post by: triumphjon on November 19, 2010, 08:36:30 PM
ours is near to where the rope & general ironmongery is , stainless steel bolts ive not found in a b&q , being on an island surrounded by salt water our local nut n bolt shop sells stainless fixings for a lot less than the marine shops do !
Title: Re: wee nip modifications !
Post by: Dekan on November 19, 2010, 10:30:42 PM
My local "ironmonger" wouldn't know what stainless steel is.... let alone stock any nuts and bolts made of it!

Thanks Timo...I have order some M3 nuts and bolts from Boltit to hold the keel blade on.

I can use a fibre washer saturated with CA to protect the deck from damage by the keel bolt head...

if by ca you mean cyno adhesive then it disolves with water ! the shop here is called cp fastners  which is southsea , portsmouth .
Title: Re: wee nip modifications !
Post by: Dekan on November 20, 2010, 10:31:05 PM
Ok....No CA :o
Title: Re: wee nip modifications !
Post by: triumphjon on November 20, 2010, 10:55:33 PM
i glassed my keel bolt into the keel so the stud protrudes through the deck , then secured the keel into the boat with a stainless steel washer & stainless steel plain nut ( i need to use stainless as all of the water around here is salty or just salt ! ) having said that i dont remove my keel either , just remove the mast / sail for transport and storage , my sail control cord has a removable quick link so i can disconnect it from the boom   it was bought from a kite store . my deck covering patches are clear vynal that it used in the graphics shop ( the stuff they make stickers for signs from ) after i varnished my hull / deck & installed the servos etc i cut the oversized patches and stuck them onto the deck ! jon

Post by: Dekan on November 21, 2010, 02:14:15 PM
I have ordered the stainless bolts... but my local model shop stocks them for cars and helicopters :} but no washers :(( I must go into B&Q and get some Fablon
Title: Re: wee nip modifications !

There's a small Wilkinson store about a mile a way from where I work.... but the usually story nowhere to park :((
Title: Re: wee nip modifications !
Post by: triumphjon on November 21, 2010, 11:22:55 PM
i know that story , parking can be a nightmare here too . ive taken to walking or cycling , if i visit my local model shop as its only about a mile and a half from home ! hows the build progressing ?
Title: Re: wee nip modifications !
Post by: Dekan on November 22, 2010, 05:33:11 PM
It's progressing very slowly at the moment. The hull is pretty well done...I have ordered some stainless nuts and bolt.. I bought some 3mm brass rod and 3mm id brass tube for the rudder yesterday.

I may have a rudder arm that will fit, so I should be able to get on with the rudder this week...

My friend has ordered a Graupner Saphir  keel weight, it's a little over weight at 1.4kg...1.2Kg recommended...But it may do the trick..I still have to sort out the mast and sail

I will try to take some pictures at the weekend..
Title: Re: wee nip modifications !
Post by: triumphjon on November 22, 2010, 09:14:15 PM
sounds like its getting there , are you making one for yourself at the same time ? mine has been sailed several times and seems to handle some of the rough conditions very well . Although i had a little mishap returning from the lake last night , having to swerve out of the way of somebody , the yatch was overhanging the side of my carrier and collided with a steel post ! Result one wee wee nip ! ! as it broke the first 6" from the bows . so in repairing it ive now put more radius between the hull sides and the bottom sheet , ive also tried to improve the flat bow block by sanding away the edges .   Weather permitting there is a sailing get together next saturday at the lake so hopefully i will be able to see if its any better ?  jon
Title: Re: wee nip modifications !
Post by: Dekan on November 22, 2010, 11:07:49 PM
Jon, I making it for my friend as his eye sight is not that great..I don't really need another yacht,at the moment, as I have a Victoria and a Racing Micro Magic.. I might make some thing similar, but I would make the hull easier to build and remove the forward deck hole. Theres a Oz web site with some good ideas  http://weenipsbayside.yolasite.com/about-us.php
Title: Re: wee nip modifications !
Post by: triumphjon on November 23, 2010, 09:28:10 PM
thats an interesting site , a nip with two sails looks very interesting , ive just emailed them for further information on the set up will pass onto you if / when it arrives ! speaking of magics theres a group of gents down here who have several and are looking to race , they have an informal meeting this saturday morning down at the lake weather permitting ! im looking to attend hopefully with the nip if its repaired in time and my seawind .
Title: Re: wee nip modifications !
Post by: Dekan on November 24, 2010, 09:26:05 PM
How do you like the Seawind? Any problems with the hatch?
Title: Re: wee nip modifications !
Post by: triumphjon on November 24, 2010, 10:43:06 PM
seawind is fine , now ive stopped the water ingress , it was the usual hatch bending , ive replaced it with a 6mm clear perspex hatch , ive fitted a rubber d profile seal onto the deck appeture , and fitted 5 m4 x35mm stainless steel nuts n bolts through the deck (sealed with some silicon sealant ) the hatch now seals using some m4 wing nuts ! ive had to rebuild the keel as it looked as if the shark had been to lunch , and my rudder has been coated with grp after i dropped the model trying to load it onto my carrier , it landed rudder first & snapped ! ! the nip is having the resin n matt treatment this week , resin is taking a little longer to set due to the cold weather . having looked at the sail plan shown for fitting a jib sail , i may have to move the mast back to the first point after the keel box in order to get enough clearance for the jib boom ! jon

I've had a WeeNip for a few years now and have done a few modifications so that some doubt it is a nip any more.

When I first built it I used the sail plan etc on the plans, the mast was a carbon tube from a crashed kite this proved to flexible the top of the mast could bend until it was in front of the bows, I decided something stiffer was needed and luck came along with a load of old arrows that work were throwing out alloy shaft that just fitted over the carbon mast. at the same time I found out a bit of history and that the wee nip was built to meet the Strathclyde 70 rules this class allowed more than one sail so I made a Bermuda rig that met th max sail area. I also installed a sail winch can't remember which one but it is allowed.

I sailed the boat quite happily for a while and they will sail in rough conditions but I did launch it in to 4' swell it handled well until I lost rudder control but she in a series of circles headed off to the nearest headland where I picked her up about 1 mile sailed with the radio switched off in the back of the car when recovered the rudder arm had bent and jammed over the servo arm.

I've now extended the mast a bit more and made bigger sails the Jib is still too big and can over power the rudder. I hope to build a new one and will stick to the rules this time and hope to get a neighbour involved too,

ive managed only to find a sail plan for the mk2 nip form one of the australian clubs , its showing a jib of 250mm and boom of 300mm , with the mast in its original postion the tip of the jib is beyond the bow of the hull ? ehile looking at the gallery of the pacific harbour yacht club they have a shot of a mk2 nip rigged with both sails that puts the mast at fractionally in front of the keel box , it also shows propper rigging lines and stays ! the lake im using has winds that blow in circles around the lake .

Post by: bikemec on December 01, 2010, 08:18:11 AM
When I had the carbon mast I played with stays, at one point I had four including one from a mast head to the stern,

the heavier mast has made a big difference I wish I'd taken more photos of it during each stage of the modifications

As I'm building for a friend... I intend it to build it pretty much as designed...I'm waiting for a keel bulb at the moment... >:-o
Title: Re: wee nip modifications !
Post by: triumphjon on December 01, 2010, 04:42:06 PM
keel bulb was easy , got some sheet lead , beat the outer layer into a wooden mould , then melted strips into the hollow using my blow lamp ! i only needed a pound of lead .
Title: Re: wee nip modifications !
Post by: Dekan on December 01, 2010, 08:03:55 PM
No blow lamp.... I live in a Flat..... so no garden..I don't like handling lead if I can avoid it....Oh and the weather is Cr*p...

ive the same living problem , live in a first floor flat , hence any model needs to be within 3ft long and managable down a flight of stairs ! no garden or shed AND  i do all of my building work in our front room  except for grp resin work which gets done on the balcony ! so i know how you feel , however my blow lamp is of the small gas soldering type , if i remove the catalyst head it will provide me with a flame . my keel bulb took around half an hour to "cast "  a little time to file smooth before it was bolted through the fin and coated in resin .
