Hello and seasons greetings to all. Having just taken delivery of what I think is an all brass 350, I'm stuck with the issue of the jet and the cleaning tip. In enemy hands, someone had previously messed this lamp up quite a lot, and my first job was to crush the bottom up so it at least didn't rock all over the table. Fortunately it seems not to be leaking, and also fortunately I had a spare valve assembly and pricker rod that came in a mixed bag as the rod had broken in the usual place above the block. Neither of the rods have a tip with a wire in it. The jet was well and truly blocked, most likely with something foreign and having finally managed to get it clear, I reckon the orifice may have been enlarged to the point where it will most likely over-fuel. Just wondering if anyone out there has a potential solution to this please, as I'm struggling to find anyone that retails parts for Veritas. I'm not sure if the design of this jet/cleaner is specific just to Veritas, or if something else will fit. I'm tempted to tie a bag on this and try to light it outside anyhow, having got some cheapo sock mantles from China that are disposable at around 12p each.
Hi @ROGER BAKER I believe that you can buy some spare seals and some parts from Base-Camp, here is the link: Veritas lamp spares They don’t appear to have a pricker though. Cheers Pete
Thank you Paul. I'll give base camp a call if Pete thinks they're worth a shot. I might come back at you regarding that jet if all else fails. I've a friend who may have a drill small enough to get a hole in the end of the pricker, and find some kind of tip that will go through the hole in the jet. How we hold it in place may be a challenge as crimping it in might not be so simple as brass can be brittle at the best of times. Still, I've two dead prickers to play with! Thank you all.
Maybe use a guitar string to make a pricker. If you use a diamond stone to put flats on it you can also drill brass but you will need a lot of patience and a high speed drill. 9 thou top E is about 0.23mm, 8 thou for a 0.2mm jet size. Both are common. If you need smaller then they become harder to find. 6 thou exists but it is specialist and not stocked by many.
I have one of these just measured pricker it is .15 to.16 mm (tried a strand of lite weight (3 strand) control line model aeroplane cable .17mm, went in but a bit tight. I wonder if pricker brass holder is 2 parts the small rod pressed into the threaded part, it might be possible to sit it into a piece of steel with a suitable hole and drive it out. I would hesitate at thinking to drill a steel wire out of brass with that size drill
@ROGER BAKER G'day Roger, I don't have one but this post might help to rebuild an old one. Repairing a broken cleaning pricker for an Austramax. I have tried unsuccessfully to drill out broken steel prickers in brass. I have 0.15mm spring wire. PM me your address if you need some.
Thank you all. Graham your suspicion was well founded, as you can see from the picture I've just added here, the skinny section of the pricker is actually threaded into the wider holder. I've shown it alongside a pricker I think was from my Radius 119. This still has a hole in the tip as the wire was missing, and it does in fact thread into the holder quite nicely. Just a wee bit longer than the original, but better that than a bit too short. I'll have to look into the possibility of getting a wire to stick in it and stay put next.! We're on the right track here at least so many thanks for all your contributions.
@ROGER BAKER Alternatively, use a modern day 350cp Petromax type cleaning needle, I used one on my Veritas 350 and it works a treat. But be aware that you'll have to reduce the triangular part of the needle holder so that it will go far enough into the Veritas jet. Henry.
Thank you once again Henry. I'm waiting on a jet from Paul M, and actually do have a needle from I believe a Petromax I can file down, but need to see if the wire is a decent fit in the orifice first. TTFN Roger.
Hi there and welcom to the land Veritas . I used an OSO #3 needle i got from eBay. I had to file off the triangle edges to allow it to go into the jet, i put the needle in my dremel on slow and used a small file I may still have some pictures, ill look and post if i do, Its hard to drill out old prickers as the pricker wire is made from the same stuff as the drill.
Hello and thank you for the welcome ! I've tried drilling out all sorts of things like studs in alloy engine blocks, and yes, unless you are really lucky the drill wanders off whatever you do. Can't beat a Dremel for some things and I've four of them scattered about. One set permanently for sharpening my chainsaws.
This is the needle from my 350 , i had the same drama, the OSO #3 is very similar in length, made in Taiwan? I have no picture of the OSO#3
Hello Darryl. No sign of that at present on Ebay I'm afraid. I'm waiting on the jet from Paul before I try my next move in any case, as before I start splashin more out on a lamp that's never likely to be worth a great deal, and I might light it up just the once, I'm going to try and do this with what I can scrape together. Just so happens I have got an original Veritas glass for this under the bed. Just as well as the 9955 I have has a crack from top to bottom. Both are plagued by a stupid long handle that renders them likely to get dragged off the shelf if left fitted. Will report back when I have more to add. Thank you for taking the time to post your reply. Cheers, Roger.
Forget about drilling the wire out of the jet. Its too tiny. You'll most likely to break the drill bit instead. Get or make a new jet and needle instead.
Good evening folks. A happy ending to report at last. Been too busy decorating to find time for this, but she's now up and running, albeit with a bit of a faff. Paul sent me a new jet, and I bought the No2 size jet pricker from the Ebay seller that Darryl suggested. I chose to go for the 200Cp, just in case the 300 was too tight, and I just wanted it to go through rather than get stuck. The seller chi5972 was actually pretty hard to find for some obscure reason. Anyhow he sent if out pretty quickly. After grinding the three shoulders off so it would enter the bottom of the jet, even screwed down onto the locking nut at the bottom of the rod it would not quite go over top dead centre. I had to carefully Dremmel the locking nut a shade thinner to get the arm to rotate 360 deg's. Anyway she's got a full tank, running steadily and I'm curious to see how long she'll run on it. Pretty impressed by how bright to be honest! Thank you to all who contributed. Cheers, Roger.
I'm glad i could help out, the veritas seem to be a bit under rated, when i fettled my first veritas it was a bit of a challenge, i had never done anything like it before, i realy enjoyed working on it, the generosity and sound advice from the fellas on CPL was outstanding. Once it was lit up i was hooked, it set me off on my lantern fettling hobby, i havent looked back, and my fettling skills have grown, confident to challenge my next project. My Veritas was sent to me from a long time school friend, of recent he lost his man cave shed to bush fire, when he gets sorted im going to send it back to him, i think it will be a fitting man cave thing to have. Rodger your lantern looks so cool and bright
Hello Darryl. Yes it is extremely bright. It ran 6 hours without faltering last night 'til I turned it off, and still passes the "slosh test" so I'll finish off the remaining fuel this evening. This is one of those I'm not going to fettle any further. Original paintwork and decal are a bit tired but not crying out to be obliterated. Some lamps you just know from the start, are going to be stripped back and this isn't one of them for me at least. Not sure I have a next project lined up myself at present, so maybe when I find time to stop decorating the house, I'll have a trawl in the Bay. Over here at least, anything besides the odd X246 model are getting a lot harder to find in the wild. I've a couple of Veritas Superb models, and neither of them will run anything like right on Kerosene, but do burn rather well on panel wipe. I've also a 9955 that runs OK on Kero, but the gland on the pricker housing smokes when lit. I can't tighten it up as I'd like as you can't operate the lever if the gland nut is done up any tighter. I rather suspect that design was an evolutionary dead end for Veritas. Sorry to hear of your friends loss. The returning it idea sounds good...My woman reckons we have no need of a man cave, and suggested that since we already live in one, why would I need another. It's a good job she loves the hissing sound, and the companionable nature of a pressure lamp on the dining table of an evening...To the point where she's thinking something feels distinctly wrong if I've not lit one already.
Hello, yes, I know it is a rather old thread, but it is about the subject. I was working on two Veritas 350 lamps, the kerosine type, but one had a worn jet, hard to get on. Realising those lamps look very much the same as Primus 1020 lamps I thought giving it a try. I have several spare jets fitting the Primus 1020, but they are bigger, the thread of the 1020 jets is quite common, m7x0.75. Amazon provided me the tools, I drilled 6 mm in the Veritas generator, I cut m7 thread in the top of the generator and it works, the lamp is test-burning without a mantle perfectly. To make sure I had a perfect fit I made a lead ring between the generator and the jet. Next project, making a cleaning needle for this new situation. Have a nice weekend, Ton.
Personally I would not use a lead washer between the jet and generator, it may be O.K. for a test burn but that area gets very hot after a while and there's a good chance the lead will melt. I would just use some copper or nickel based grease on the threads to make sure there is a good seal.
Actually, the Primus 1020 jet thread is unique to Primus. It is actually 7 mm diameter but with a 35 thread per inch Whittworth profile. This gives approximately a 0.73 mm pitch, but the thread angle is 55° instead of the 60° used by metric threads. Maybe the metric thread can be forced in, but it is not the correct thread. Primus being part of the Bahco company had all the resources they needed to make their own threads and this ensured customers had to use their spare parts. Makes for a problem now though.
@vissertw , hi there, it is an old post but I liked reading and searching them for practical solutions to some issues and not knowing the more technical aspects of the workings of the lanterns. If you are looking for a pricker I found on the dreaded eBay a site selling pricker of different CP OHO# 350 it was a Taiwan site. I have bought many different jets and pricker cleaners. For the Veritas 350 the pricker will need to be filed diameter to fit the jet. If you have the skills set you could make your own Enjoy your Veritas. Long preheat use a long mantel Hours of fun
About the small ring, washer under the jet, until now, during testing time I will certainly keep the tip about copper washer and paste in mind. About the thread, I did not know about a Primus thread to exist. But, it is very near the M7x0,75 and I have several 1020 jets, all of them are easy to screw in by hand, without any force and certainly not too loose. Maybe not perfect according to the Whitworth profile but it does the job. About the pricker, I have read about the CP OHO# 350, but with the 1020 jet now I have a much wider jet. I will have to work out what could be the best solution, maybe an original 1020 cleaning needle, only figure out how to fit on the Veritas rod. Regards, Ton.
