- found this British silver seagull outboard engine while out yard sale shopping, the seized engine does not look like it has had a pampered life. so shall we take it apart and see what happened to it over the years.
Get good x-rays or scans of that neck. Me and wife also had a crash like that and she ended up with a slight pinch in some of the disks, causing sometimes numbness in the arm, and neck pain. Don't let the insurances get away free.
Cheers Darren, and speedy recovery.
I went through it too. Surgery worked wonders...only twenty years too late.
Yeah it may never heal. At least not on it's own. Was in a very serious accident many years ago. Had two herniated disks. The bone in the middle was pinching off my spinal cord. That didn't show up on x Ray's!
He should get an MRI to be safe. Stick it to the insurance company. They will do anything to stick it to you.
Chiropractor saved my writing career when (allegedly) repetitive strain turned out to be nerve compression in neck and first rib/collarbone area. He said I’d had a whiplash at some time in the past.
Another chiropractor got me through an L5-S1 herniated disc.
I have had one of these Seagull outboards for over 20 years and never seen it run. Going to give it a go now I've watched this 🔧👍
Got one from my father when I was 12. Well a Seagull engine at least, just not this model. Dad shortened the shaft enough I could use it on a rowing boat. I think it's an older model than this one as the carburetor in the one in this video seems a lot more advanced, and the one I've got doesn't have a clutch of any kind. The engine runs the prop is spinning, you've got no choice. Well dad dropped it in in the sea once, but fishing it up and draining the water was enough to have it chugging again.
These are not performance engines, that much is certain. But they pull way more than you would think. A slight accident happened once and we got a rope in the propeller on our boat as we were about to move. Thing is there was a hail storm with a lot of lightning coming and it shifted the wind direction 180 degrees. So not only were we to get the wind from the stern, but there were going to be a lot of it. Well I jumped into the rowboat and cranked the Seagull. I was able to pull the boat against the wind while our friend who had a working diesel engine was unable to keep up. That old piece of junk really did work well. I've still got it in the basement, and, using the used car dealer voice, works perfectly. That really means that the last time I used it over 30 years ago it ran.
The problem with getting the flywheel off is detailed in the instructions which is available online. There's a trick to doing it but I can't remember the details. Just about all use of a puller or trying to use leverage as Mustie did is almost guaranteed to break the wheel.
I had an old Elgin 3.5 HP canoe outboard from the late 1930's, the one where you can turn the engine around 360 degrees from the transom mount to reverse. Turns out they're really, really rare and that engine ended up in the owner's of an old motorcycle/outboard museum collection when I traded it for a few repair parts. He told me later I could have traded it for a complete and running 1960's bike from his collection. Little did I know..
Ive had one for 30 years. Dad gave me one with an old aluminum boat and they both needed to much work atthe time. Maybe I have time now as I still have both the motor and the boat.
I had a 1.5 hp Seagull on a rowing boat. Didn't exactly break the water speed record but it chugged along for ever.
And they say the Germans over complicate the obvious!
I figured you would have to refer to your light as a torch, and your wrenches as spanners for this episode...🤓
British speak. Lol 🤪
@@danielsweeney6742 Yeah, the Brits know how to speak proper English. 🙂
You've never seen so many twitchy gun hand Police pour out of a Watch house at a Los Angeles Police Station in 1979 when a Kiwi wanders in and asks where he can buy a Police torch.....
The female counter server screamed "He wants a Police flame thrower" at those inside the office.....
An old detective also came out and said "You're not from around here are you???
No Sir
"We refer to them as a flashlight....
see X on Y boulevard they sell Police flashlights".
Kel Lites that were invented by two serving Police and ultimately resulted in the Mag lites of today.
On the flywheel, the flywheel is being raised for use as momentum to pop it off the shaft, in which case hammer speed is important, so I would us a smaller hammer but swing it faster.
..."Limey lingo"...(?)
Ooh my word, these are absolutely CLASSIC machines, pure simple with a very rich fuel/oil mix I believe. No gear lever so constant engagement.I love the outboard repairs.
The plain bronze bearings require far more oil than roller or ball bearings....
British seagull, 3-5 hp, the 6 bladed prop is a pusher prop..
British commandos in ww2 used them for pushing their rubber boats , .
These are a fantastically reliable motor.
I owned several and rebuilt them ,
This one is 5 bladed, maybe a different model.
@@worldofrandometry6912 yep.
The propellers are interchangeable, through all models.
Gear ratios are the same, very simple motor, the units I owned were at least 30 years old when I got them, and they ran perfectly, they are noisy, but a great motor.
It's a pity the 1 Mustie got was a total disaster , internally.
@@jeffreylord8172 The propellers are not interchangeable through all models.
Some of these engines were fitted with lignum vitae wood bearing for the one way crossing of the River Rhine in 1944. Legend has it that some were returned for servicing by locals after using them for 20yrs still with the wooden bearings. Spares are still being made by the original company although new outboards cannot be sold for environmental reasons.
That will green things up alright
@Turnipstalk Lignum vitae is so good that we harvested it almost to extinction.
Big ships often have stave bearings made from phenolic laminate.
A do not remove warning is like an invitation for Darren 😁
Hey, you and I are getting up there in age!! You do so much more than lazy me, so don't overdue yourself.. Hope your neck starts feeling better soon!!
Darren, you should get 10 gallons of evaporust and you should soak these in it for a week before you start. You would be amazed at the amount of rust that it would remove, it has no acid so it would be safe for the entire unit.
The spring is also the shear pin to keep from breaking the prop or drive gears. Pretty good engineering.
The stories I heard years ago were that the Seagulls were lifeboat engines and the military specs were that they had to last two days. If you weren’t rescued by that time the chances were you weren’t going to be. They were intended not to move the lifeboat around but to keep headway into the seas to avoid capsize. The story also was the tool kit consisted of a 2 size spanner and a screwdriver so an ordinary seaman could do minor repairs. To everyone’s surprise the engines proved to be much more durable than they were speced to be. I’ve seen them on many sailboat dinghies. I believe they’re still being manufactured.
Good morning from Montreal Canada 👍🇨🇦
I think the last time this outboard ran was docking the ARK to Mount Ararat, for sure it sat on the bottom of a lake or pond for many years. 😮
One thing about these is you can get just about any part for these from the company that bought BSS when they decided to close down in 1996, whilst not common in the US they are to be found in Canada, Australia, New Zealand and much of Asia esp Hong Kong where these were used to power small junket craft around the harbours and those would migrate to other parts of China like Shanghai etc. Over here in the UK £200 buys you a fully working clean 1970's version, a resto from the 60's for about £80 and £130 a 1950's dry stored "barn find". Whilst they were not racing engines they did propel a craft well, in short these were the Mini engines of the water, solidly and well built very dependable machines. British Silver Seagull didn't actually go bust, they decided that with the takeover of much of its business markets by Chinese and Japanese imports globally their market share was dwindling and decided to just shut its doors and lay down its wares peacefully, kinda like Reliant did not so many years after.
They couldn't keep going without a total rework of the design for environmental reasons. Seagulls are crude beasts, no seals on the lower unit (it just floods with water that mixes with the oil, which in turn slowly leaks out) and bronze bearings in the engine which forced the use of very oily premix, in short they're a mobile environmental disaster. Staying in business would have required a clean sheet engine with proper seals, roller bearings (so the premix could be more like 50:1), and of course the modern conveniences like a recoil starter. The cost of that kind of development work was more than the company could bear.
It's sad that they weren't able to continue, because the seagull philosophy of swinging a big, slow turning prop is ideal for pushing larger displacement hulls around. Their Asian competitors all spin a pathetic little propeller really fast, so the engine does more work stirring the water than moving the boat. Perhaps if they'd been able to get ahead of the game and put a reasonably quiet and reliable 4-stroke on an updated lower unit... ahhh well, a man can dream.
Happy Father's day to all the dads out there
Thanks
Thanks!
👍🏻👍🏻👍🏻🏴🇬🇧
thank you, even my son didnt wish me it
Thank you! Happy Father’s Day to you and all the Dad’s! 🔧
Thanks for the tear down. That motor is trashed bigtime. Happy Father's Day to all you Dads out there.
Happy Fathers day all Dad's. My father had a similar seagull outboard on his 16 ft yatch as an emergency engine. I was about 10 then Now 65 all i remember he rebuilt it before he used it so that engine is quite old. By my reckoning the one you have is a series 40 dated around 1955. Thanks for the full break down.
That's a 5hp Silver Century Plus, clutched with forward and neutral only, for reverse you literally spin the whole engine in it's transome clamp,Amal carb with a float bowl tickler button for enriching the mixture for staring, absolutely bullet proof engine, I've personally witnessed one jump off a transom and go under water and come back up still running 👍 fabulous British engineering from a time when we actually had a decent manufacturing industry
Instead of Kroll oil, you might have used Evaporust. Evaporust ‘removes’ the rust and makes it way easier to take rusted parts apart.😊
He was too impatient for Evaporust. Plus, Evaporust costs money.
@@georgepretnick4460they could sponsor it, just saying.. Though I'm not sure Mustie would be on board with that kind of arrangement.
@@macbeth2354 He was previously sponsored by 3-in-1 Oil. That didn't go so well.
I was rear ended at low speed, but I was leaning forward and looking to the right, and snapped my neck on impact. The driver was an unlicensed 15 year old who took his mom’s vehicle without permission. The bumper was scratched, but no other damage. Three days later, I couldn’t move without extreme pain in the neck. The emergency room gave me some muscle relaxers, and some good pain pills. A few days later, no more issues. Whiplash is a real thing.
Even though it didn't run, a Mustie1 video with flames is always a winner.
i miss my father, him and i used to tinker all the time. thanks for letting us tinker with you on this day.
I hope you feel better soon Darren. I've seen every one of your videos from the start,and were getting older and it sucks don't it!! Always fun to watch you. You need your own TV show. It would be a big hit!!!!
These are legendary little outboards, not designed for speed, but long efficient use in small fishing boats. They are well built, and made to restart after a dunk in the sea.
That is a well used looking example.
The drive has no shear pin to fail, it jumps if the prop hits or tangled in a net.
I’m sure you can revive it, they are pretty robust.
Spoke too soon, to free the flywheel wedge it like you did, but many gentle taps with an air hammer will release it.
To free the piston, air hammer with a rubber tip, stick it through the plug hole and rattle on it for 20min or so usually does it.
It’s horrible watching, going ‘no don’t do that’
That piston is fine, the rings are stuck, clean up the outside, then stick it in a pan of motor oil. Heat till it’s about to catch fire, then let cool, after a few (maybe quite a few) cycles the rings pop free due to different expansion. When free, clean the ring grooves, should be good enough to run.
The company still sells parts, so you could fix it still, with a new flywheel, a brave man would weld it back together and call that good.
Everything is fixable if you throw enough money at it
@@bensmith4563 sure but parts are not expensive, 40 ukp 50 Dollars for a rebuild kit, including pump, gaskets, head gasket and piston rings.
Flywheels can be had in Canada for 13-15 dollars.
Happy to source and forward the overhaul kit from the UK if wanted
I still believe you can make anything run. This is not your failure. Love your videos. Makes me go ahead and try it out.
Missing your eclectic knowledge and approaches from my feed couldn’t remember if you said you might take a week off but hope to see you this Sunday
That was a British Seagull Silver Century (100) Plus Long shaft 5.5hp outboard motor built in March 1971... RIP😢 gone but never forgotten
My dad had one in the 60's, would never start when needed.... Not Britain's finest...We needed the Japanese to show the rest of the world what "design for assembly, maintenance, and repair" looked like...Mustie, I applaud you for your persistence and good spirit. This repair started hard and went downhill from there. This was the first of your postings where I thought: he will never fix this...Keep them coming!
Fuel, spark, air.
Sort these to standard and it must run.
You mentioned a Larsen outboard at the end. My Uncle had an old one just like the one you showed I think it was 6hp. We brought it on vacation, the place had a boat but no motor. We went fishing in Saranac Lake and that motor worked great until I saw a flame burning inside where tge throttle was controlled. I was driving, 10 years old so this was 57 years ago. I said hey uncle Phil is it supposed to have a flame inside ? He came back and turned it off and blew the flame out. So funny. It was a 2 cycle. We had to row a long way back. After watching you I am assuming it had a leak in the carb somewhere. I’d love to watch you take that Larsen apart. I’ll bet it will still run .
Dear Mustie1.
😱 I was shocked to hear that you still suffer from back/spine problems caused by the car accident. Hope the insurance of the other driver pays your physiotherapy bills. Get well soon, Sir.
Best regards, luck and health in particular.
Fun to watch the dissection of an unusual engine. Some can identify with me as a youngster, I used to take machines and electronics apart to see how they worked, even if I could not put them back together again. As long as they were junk, my dad didn't care.
Mustie … I been watching for years now ….awesome person u r !
I thought , when I was watching this video , that I wished you would go back to those days when your videos theme was creative bike building …. But I think your videos now are more creative & with a narrative of projecting cool insight . Thank You ,our friend for your Sunday creative genius 🇨🇦😀😊🇨🇦
You gave it your best,Darren..

Good Morning from Massachusetts USA ! Happy father’s Day !
We had a Seagull engine on our little dinghy when i was a kid. I can vividly remember my dad thrashing at me with the starting rope when i accidentally stalled it and he couldn’t get it going again. I was pretty glad when he got a new Yamaha outboard..
"The disassembly will continue until morale improves"
I love how all the British and Commonwealth viewers came out in force in the comments. Just goes to show the broad reach and appeal of a Mainer just working on "stuffs." Cheers from a Texan that works on "stuff."
Sheridan marine still stock almost every part for those old seagull outboards... piston, rings, cylinder, gaskets and flywheel are all in stock!!
Or SOS UK Save our Seagulls in the UK..
these were popular in Australia in the 50's, they are popping up here and there at garage sales now, $300 aud for running model. hardware should be SAE or whitworth type, reverse is just turning the engine around on the mount to pull the other way
It was sad to watch the destruction. There are methods to get it apart without breaking and cutting everything. Ive restored many old engines and it takes time and care not to break unobtainable parts.
A couple of minutes on Google would have saved the flywheel from destruction.
She's knackered, mate!
Absolutely the easiest outboard to service and repair. Not environmentally ok nowadays but still great.
Nothing Mustie works on is tree hugger friendly, lol
Because it’s a two stroke ? A little smoke is not unfriendly . Millions of tons of lithium is the danger to the environment. Not a little oil burning .
@@Philc231
Millions of gallons of oil spilled into the environment every year are orders of magnitude worse than lithium mining.
Look are the facts before spouting irrelevant BS.
They are as you can see impossible to work on due to corrotion issues together with strange thread sizes..
They usually end up as junk..
@@Philc231trouble is they use 10/1 mix. More than a little oil 😳
Some modern 2 strokes use 100/1
I was told by an elderly gentleman at my local sailing club that he used to work for British Seagull. In the mid 70,s a ship full of brand new engines was scuttled in the English Channel.
Apparently due to health and safety and emissions policies drawn up by twonks in high office. Perhaps they had bought shares in competitors companies.
Hope you are doing well, wondering why no video this last Sunday...? Great videos
If I remember correctly, the Silver Century Seagulls with the prop impact, spring, wedge type prop clutch and Electronic ignition were introduced in the mid 1970's. That one also has the later carburettor, but an earlier long range fuel tank? 2 stroke oil mix was 20:1 The gearcase was filled with SAE 140 oil and no seals were fitted, so some water was allowed into the gearbox. The water pump impeller is a nylon paddlewheel, not a Jabsco type. These were often used as a dinghy motor which doubled as a small yacht auxillary engine. There was a weedless propeller as an alternative for inland waterways I have an old 1.5 hp Seagull with a brass fuel tank in the garage!
“I see… rust.” I laughed out loud when you peeked into the cylinder. after taking the carb off.
No reverse, just turn the whole motor on its mount to go astern. I remember my father groaning on discovering he'd hired a boat with a British Seagull in Glengarriff in 1967. Mind you, he got it going and we caught no end of mackerel out in the bay.
That water looked amazingly clean that poured out of there.
I actually have one in my shed, here in Australia it's a runner when I put it there 😂 only 20 years ago 😂 thanks for sharing, all the best to you and your loved ones
Happy Father’s Day Darren. I really enjoyed this teardown and I agree, the time and effort to restore it proper like would be enormous. Your videos are just as educational as they are entertaining. Take care of yourself, none of us want to see you in a neck brace making videos. Thank you so much for the untold hours you put in making these videos.
This is an interesting video. I have never seen a British Seagull being taken apart before, and especially in that fashion. Lol. Sad that most of those outboards are so badly neglected. Another good video.
I absolutely love this channel!,, Mustie is so funny! Great sense of humor 👍👍👍🇺🇸🇺🇸🇺🇸
Those British Seagull outboards were very popular as a dinghy motor in the 60’s and 70’s. I had one back then. Very simple machines, easy to work on.
Like you said, I think that one has been under water for a long time. I’ve seen some that had fallen in or dropped in salt water that were brought up, flushed out and made to run. Not sure when they stopped making them.
Another excellent teardown. Have a look where you rope start on the top of the flywheel.
It will declare its "The best outboard motor in the world" or, if made after the mid 1960s it will say " The best outboard motor for the world".
The company that made them must have been told off by the more modern outboard makers for making false claims!
love watching Mustie videos but the real pleasure is reading the comments on these videos with old weird things in them and realizing how many people know what things are and how they work. Comment sections are so funny, half of us are just here to toss out a few smartazz comments then the others are here actually giving out decent info. Thanks to both of these types of people!!! LOL
Thank you for sharing.👍
Even though the thing couldn't be saved it was a cool learning experience.
I used to help a friend fix those for another friend that had a marina -- I don't think we ever came across one that we couldn't get running.
Mustie, they built motors up into the 90s and always kept the small ultra simple design....I know it looks a lot older than what it probably is...but believe it or not, they still make spare parts for them. It's my understanding they stayed popular till the end but new emissions standards basically shit them down
Ha....thanks auto correct.. "Shit" instead of Shut"
Seagull s**t....
I see what you did there and I commend you for it!
@@JohnSmith-pl2bk LMAO....hadn't thought of that. Accidental brilliance

It's the original and the best, old boy. Though I am partial to the odd BA thread myself.
Great outboard engine for a small vintage sailboat. Just a gem😊
First thoughts at half time : Maybe "Do not open" is some clever engineers way to tell you that it is not worth the time.. like in "Do not open, throw directly into garbage" .. but it's vintage.. so jeah..
Precision British engineering secrets inside...
don't let the magic smoke out.....
oh wait...
I also own a British Seagull outboard that I have never run - and now I have the Mustie version of a Haynes manual for it!
Another enjoyable saga. Thanks for the journey.
Mustie, I've come to the conclusion you're a 'Hoarder' of many things - mechanical and otherwise... But I enjoy listening to your ramblings - always educational and often amusing!
That poor thing looked like it spent some time at the bottom of the lake. Interesting and amusing video nonetheless. Thanks for all you do.
Had one of these, - the general problem with these engines is heavy corrotion, - allthough mine had a pitted cylinder where the piston sat and overall badly corroded aluminium parts it still ran !
Good Morning Mr. Mustie! Thanks for another good one! Definitely an interesting outboard you have there...
Greetings from the Balkans! American traveling in central Europe, and I was at the "Museum of Science and Technology" in Belgrade, Serbia yesterday, 6 July 2024, and saw one of these British Silver Seagulls in their collection of outboards!
I told my significant other, "Mustie just had one of those on a few weeks ago!" Response: "Who's Mustie?"
I thought you were a household name now, among 40-something American women! 😂
My first boat at the tender age of 7, was a 14 foot bondwood boat with a seagull, you had to spin the motor 180 degrees for reverse.
Moved a 65ft steel canal barge many miles to dry dock at 1 mph with one of these, a 15 hp Johnston couldnt do it, they are a low tech legend .
Projects like this is what made me subscribe years ago!
I was watching this for a few minutes and I thought “that looks like it was in the bottom of a lake and someone found it.” And sure enough Darren said almost the same thing when he looked down the shaft. That is one old motor. Maybe it cracked off a rotten transom in a storm. Went right to the bottom.
Seagull is a true Datum for what was once great about our Once Great Country
They were used to evacuate our Soldiers from Dunkirk
That is a Accolade in its self
I am sure that I once read an engine was found on the Seabed that was used on the evacuation with some work it ran again
What more can I say
Rule Britannia !!
If only we could go back to these Great days of our once great Nation
I have a seagull that was my Fathers
We have had it for over 50 years
It is the epitome of simplicity……. but it worked then and will work forever and a day 👍👍👍👍👍👍
He got a chance to use the ‘it’s not terrible’ line on this one!
Hope you got out of the hospital this morning as planned fell better Darren !
Dual-wielding torches and making fire tornadoes. Badass. 😂👍🏻
you know things are good, when its a double torch episode.. :-)
Man doesn’t curse very often,but when he does it’s appropriate!😂
Had one years ago put the carb back together wrong. When I started it it ran at full throttle. Tried to take the spark plug off to stop it but it was those old screw on type shocked the shot out of me, eventually flipped the dinghy upside down and drowned it. HIND SIGHT says put your hand over the air intake put in the chaos who would have thought 😅
Morning from sunny MN Coffee crew!!
A friend of mine had one in excellent condition. I noticed the choke lever on it is the exact same choke lever I have on my '72 Triumph Daytona.
Those are great little putt putt motors. I love the sound of them.
Thanks, gotta love the Mustie chuckle!❤
What a treasure, I remember seeing them in AUS in the 50s. They didnt have a reverse, you just spun the whole motor around from what I recall. Bad luck you couldn’t save this one.
like a trolling motor
Dad had a Seagull on his dinghy years ago, I have not-so-fond memories of starting it with the lack of recoil starter.
Maintenance kept up and all parameters in spec.......and they don't even need a rope to start.....
These were THE dinghy outboard motor when I was a youth in the 50s and 60s. There were a few Evinrudes as serious competition, but the Seagull came in about four power variants from feeble to 4 and a half hp and were dead reliable if looked after. Some lake bound and inner harbour rental dinghy operators used them in their craft as they usually weren't powerful enough to get the inexperienced into too much strife. But you are right - they did tend to leave a pretty rainbow haze in their wake from the very rich petrol/oil premix! Maybe modern synthetic lubes would do away with some of that by running at 50:1 Col, NZ
The reason why a British Seagull engine needs a lot of oil in the fuel is that it has plain bearings throughout. This is also the reason why they survive being immersed in sea water better than other outboard motors. There was a late model that was redesigned in consultation with Queen's University of Belfast that did not need so much oil but it still did not satisfy Brussels. I think the critical part is the connecting rod big-end. I have a 1940s Atco-Villiers mower engine in which the big-end is a roller bearing and the small-end and the main bearings are bronze bushes. With modern oil this is quite happy on 25:1 and does not make any smoke at all.
Darren I must say,first you win sometimes and you lose sometimes but regardless fun video, and second, thank you for your always interesting and engaging videos, your videos on the Trials 250 Honda (about 5y ago) helped me doing some routine maintenance on my partners 250 rebel carb, and how to explain how things work in it, thanks Mustie, keep up the amazing videos
Thanks for trying Mustie 😊
Brit here, very concerned you seized this engine. We want it back! Thanks in advance.
Seagulll outboards are very collectable.
You tube Dr here! You definitely need to work all those muscles around your neck. Traps, upper back, neck, shoulders. Most people totally neglect their muscles. The accident probably made them all tight and they are guarding. Get a good massage therapist to dig in. Most most most not all physical therapists are all part of the system. Come back a thousand times to fix 1 issue. Good luck Mustie.
I was really expecting to see this thing running at the end. :)
They make great anchors, for a trot line. One of those jumped off the transom of a boat I rented and landed on my arm, broke one of the bones and fell overboard. I then had to row back, it was really fun. Some people love them, I do not. Your conclusion is correct
So who forgot the basics when encountering an outboard...
check check and check again the transom hold down bolts BEFORE every use???
@@JohnSmith-pl2bk Didn't expect to have a problem with a rented engine on a dinghy. I was also very young, excited and caring for my younger brother. It had thumb screws and a safety cable. Glad I provided you a teachable moment.
@@zworm2

Still boating?😁😁
@@JohnSmith-pl2bk Yup, still boating!
Mustie uses his body & fender hammer on the head bolt with a 13mm socket! A Fathers Day special from Great Britain-----good show Governor☆
Feel better. 👍😊
Next idea....in lieu of a spare motor that needs parts...
I'm wondering since your lower seems usable ....
What do you have for a small vertical shaft lown mower engine.. you could go lawn boy or similar if you want to stay vintage 2 stroke.... or use a 4 stroke for better dependability. Just a shaft adapter and adapter plate would be needed. No worries with water cooling as you would be air cooled. You could adapt the exhaust to the water discharge exhaust tube. I know. It's just effing around, but would probably cheap production cost that would be entertaining
Would be great to see it, as a conversation piece, driving a large overhead fan in your workshop!
