Fabricating a battery mount for the Tiger Cub // Paul Brodie's Shop 

Paul Brodie and Allen Milliard would be unstoppable if they ever teamed up. My two favorite youtube channels for sure.

Your craftsmanship is impeccable. Spanning decades, your drive to create and make the world and your medium your own is an inspiration. Thank you to Mitch and you (for allowing Mitch to share) for taking us behind the scenes with a modern times Bikelangelo.

Your videos are not only educating but also very inspiring, thank you very much for sharing your process Mr Brodie! Mitch is an amazing videographer. Very very grateful to be able to watch these videos

What always surprises me is that a man whose work is just perfect is genuinely surprised when it turns out just like that!

This video wins the annual "Best Creative Use of a Norton Commando Isolastic Mount" award!

Simple is always best unless overly complicated is cool.

One of the old jokes about British bikes was that if there was no oil drips underneath them, then there mustn’t be any oil left in it! Like what you do, and I hope your health continues to improve.

"Have to have an eye." You certainly do! Thanks for the video.

Thanks for having us into your shop!

The word you’re looking for is perpendicularity 😊 Loving the new vids. Hope you’re recovering well.

With old British bikes an oil leak is a good thing. If it’s not leaking it means there’s no oil left 😂 I cheered when you mentioned Alan Millard, my dream collaboration would be you, Alan and Craig Jones from Doghouse customs.

i am enjoying the videos you show us. Your lessons are very enjoyable and show how you can make a perfect engeneeriung craftsmanship . After we visited you in your workshop in September 2021, I enjoy the videos in which you show your professional work on mountain bikes and motorcycles. Your lessons are very enjoyable and show how how can make a perfect engeneeriung craftsmanship . Go on and keep out the hummingbird out of your shop.

Very nice Paul. Your attention to detail is admirable and makes a difference in the end result. I appreciate your willingness to share.

Liked the way you used vice upside down on the saw. Brilliant

Maybe you think I'm crazy, But Paul Brodie I love you! Your calm voice, craftsmanship, vast knowledge and smile make my heart beat faster when I watch your work. The more so that I repair old motorcycles myself and I would dream of working with you someday. In Poland, people like you are said to have golden hands. Yours are gold and have platinum nails :)

I heard about this guy Allen Millyard and his hacksaw…… classic!! Excellent as usual Paul, thank you!!

Hello Paul, really enjoying you being back at the tools! I had to laugh at myself, While watching you fixing that switch I was egging you on to recess the switch plate into the surface to make it flush………you must be rubbing off on me! Thanks to you and Mitch for the video. Best wishes Kevin.

All that beautiful work only to use zip ties to secure the battery. 😂👍👍

So good to see you're doing better. Thank you for the new video.

Perpendicularity, Paul. It was on the tip of your tongue! As always. Great video. I have exciting news! After almost a year of telling you that I was getting a workshop, my slab was poured, on Wednesday!!!!! One step closer to bliss.

The perpendicularness, ... thank you so much I actually lol on that

Your a fantastic engineer, and a great teacher. Btw the cub is not leaking. It’s an english bike, it is just marking it’s territory. Best regards, from a prior BSA A65 and A10 owner now Ducatista.

Thanks for the Cub videos, Paul! My cub has been on the road now for 8 months. I am always waging war against oil leaks- oil just doesn’t like staying inside the Tiger Cub engine, obviously! One annoying source is the outer timing cover; from there it leaks onto the oil lines and drips from the oil line union nut. And I don’t think the Cub engine breathes well, so that exacerbates the leaks when the engine is rinning. I don’t get a lot of leaks when it’s not running. After a ride, I’ve just got used to wiping the engine clean. I’m at a stage now where the leaks are not gone, but tolerable. Regards, Al

Great video Paul , thanks for posting

I could watch you work all day.

Thanks Paul & Mitch! What a great episode! Your brackets and braces are truly wonderful pieces of art. About the metal debris on the lathe... since it is a cutting tool, think about cutting yourself some (well-deserved) SLACK! I was trying to remember who it was that put a tap into a lathe or mill chuck to get absolute perpendicularity. Dang! it WAS you! How about using a drill press following that same idea. Now your hole drilling/tapping turned out perfectly just by eye, it might be easier with the drill press. That oil drip-drip-drip is annoying, but I have every confidence that you'll find that source and fix it. You have skills! Looking forward to the next one.

Great job Paul , one of my fav little Brit bikes 😁😁🤘🤘

Very creative battery box and excellent video, thanks for sharing 👍.

Fantastic, mate. A cool, calm session in your shop is better than a trip to the therapist!!!

Alan is just lovely

Great to see you looking so well Paul, stunning exceptional work as usual.

Alan Milliard has done some amazing motorbikes and engines. Watching his YT videos is fascinating and everything goes "just so". I wish it did in my workshop. He is now on UK tv with Henry Cole, who you may know through the programmes he did on the Worlds Greatest Motorbike rides.

One mans oil drip is another mans beaver ! Put that on a tee shirt , fluorescent dye in the oil and a fluorescent light it’s magic.

First! Im so excited we get more motorcycle content! Wishing you well on your journey to recovery Mr. Brodie!

Perpendicularity is the word you were looking for.

Hi Paul, Hi Mitch...I have been smiling for the last 22:34 minutes! As a blacksmith and professional instructor for metalwork in my first career and a studied industrial designer in my second, I have to say it couldn't be better. I say this in deep admiration. This is pure entertainment. I always thought perfection is nice, ok, but also a bit boring. You proved me wrong! Guess every profession has its "Mozart" Another comment called you "Bikelagelo".. That's good too! I can’t wait to follow your next challenge! Thanks for everything and all the best!

I just visited the otherworldly Barber Motorsports Museum in Alabama, and a huge highlight was the 4 Millyard bikes they have on display. A definite low point was the absence of a Brodie Excelsior. It is a glaring gap in their collection.

I feel good energy in this episode 👌

After sanding mating surfaces on a flat surface with sandpaper glued to it, I used contact glue to both sides of the mating surfaces and gaskets made from a grocery store brown paper sack. They were a bit thicker 40 years ago. My bsa never leaked from those joints buy the primary oil drip that lubricated the final drive chain would drip on the ground until I made a drip adjustment screw.

Super work as always. But I think the 6061 plate should be higher that the battery does not stick out at the top. I would not wonder if you wouldn't have fixed that by your next episode already. Can't wait to see the tiger cup running.

Take your time, we're mot in any hurry out here Paul.

Great work Paul. I like working with aluminum too!

So much to learn from you as usual, thanks for putting these videos out. Wishing you the very best with your health.

Great job on that mount! I like how simple it is and the two mounts are exceptional of course. Maybe some nice acorn style nuts to cover the rubber isolator threads on switch side?

Its Been a While But Iam Back again LOL. Always inspiring to Watch the Master at work. Iam Back on My Cafe Racer Build so iam here Pinching some of your Ideas :) Ie rear Number plate facia Bracket. and i have Been toying with ideas how to mount the Battery and Type of battery to use. Keep Well. Dave from Australia

Thank you Paul and Mitch, that was a fun one. Will you have a side cover?

Perpendicularity I think is the word you were looking for while tapping those holes.😊

Nice to see the art in the craftsmanship, those sleepless nights sure pay off...

great Paul! you look much better then your last video! Keep the shiny side up!

Great work as usual, not so keen on the zip ties, looks like the sort of job I'd do!

Great job as always

Brilliant to see you back in the shop and looking well ! Excellent craftsmanship as usual, some nice domed nuts mite compliment the bracelet nicely 😊

Thanks for the video. That offset with the dampers is something I’ll remember for future projects. I love picking up all those neat little tricks from you and Mitch. Hope all is going well with your health!

These rubbermounts exists in all kind of styles;-) With a bolt on each side, with one bolt and a female thread and female threads on both sides. IMHO using the version with two female threads and countersunk screws look nicer.

Thanks Paul.

Alan milyard,.. is just as amazing as you are Paul !!!

*I think Mitch should do some shop work while you film him.* 😆🤣

I believe Perpendicularity is the word that you're looking for.

Paul you are amazing…

Such great videos. Love seeing the building process and how Paul designs and constructs things, just so well done and enjoyable to watch. Mitch does great as well. Thank you both for awesome videos on these things, everything from the bicycles to the motorcycle stuff.

G'day Paul, The radiator mounts you're using are available as male-to-male, female-to-female, & male-to-female. You might be able to make a cleaner bracket with male-to-female mounts. Keep up the good work, & get well soon. Andrew BTW, your lathe tapping method never ceases to scare me. LOL I'd tell you to be careful, but it's obvious that you know what you're doing.

I had to chuckle when you mentioned Allen Millyards hacksaw and compared it to yours. It was really an unfair comparison because Mr. Millyard’s hack saw is, like the hammer of Thor or King Arthur’s Excalibur, an implement of almost legendary status. That said sir, you and Allen Millyard are on about the same level when it comes to two wheeled, fabricating wizardry. Thanks for sharing your shop.

Yes I did enjoy it and that oil leak is puzzling.

great job, but Im not sure about the zap straps. I think a nice alloy strap clamp drilled with holes would look more pro.Thanks for the video. Take care Paul.

Really happy to see these regular uploads Paul, must mean you're feeling better. Always such a pleasure to watch you work, always coming up with on the fly solutions and always working so precise. Curious how come you didn't machine a flat spot on the "shelf" for the battery to help it sit more stable? I'll put everything I have that Mitch had ZERO film with him, but lots of Flash 😛Will share a little funny - when you were holding the thicker piece of alu, it was upside down and I read "1909" and had never heard of that before, so went searching to see it's properties and why you would be using it, then came back and watched further, you held it right side up and then, 6061, made a lot more sense 😆

(Perpendicularityness is how good, perpendiculus - how bad). This thread cutting looks fine!

Nice job Paul. I think I'd use the old style rubber cable straps but it's individual taste. A very nicely executed part. Best wishes, Dean.

great vid. thanks mr brodie.

Hey now, I was trying to go to bed!

I'm not a machinist and certainly haven't memorised lists of such numbers, so when it comes to tapping holes, I just use any old drill 0.5mm smaller than the tap and hope for the best. So far so good! (I'm never tapping new holes into anything of significance, and my taps were never of any significant quality). As for that switch you used... that other nut on there is just to space it right when mounting to sheet metal panels. Remove it and it'll get you a few more threads. No milling required. :D

👏👏👏👌 Cheers Chris

Nice work . That is one heavy looking battery mount though ? I would imagine that the battery will be removed for charging , since you decided to run without a generator , or dyno . Is that why it is held with plastic wire straps ? That was a good shout for Allen Millyard too ; his Kawasaki V12 2600cc and Dodge Viper bikes are especially awesome ! He would probably make a small Triumph Trident engine for your Cub frame , but I expect it would have three times the oil leak . Lol . No , joking apart , I think you will be striping the right side engine case , but that aught to be easier than welding the oil tank surely . Best luck

your recent set backs put quite a scare into most of us but this video, it seems, you are feeling better. I enjoy the time spent here and thanks for your efforts....Mitch too

Hi Paul, I hope that your health is improving. To the battery mount, I think that two rubber mounts would have been enough. On the other hand, I think, that the battery mount should be better, specially on the bottom, the battery might crack. And those plastic cable ties are a joke ! Got a real fright by the quick tap !

Great work as usual, I also subscribe to Allen’s channel you share the same eye for detail and you both make quality work look easy.

hya dynamic duo, 😊that was ace fabricating paul, efficiently flowing between turning milling brazing tapping sand blasting bandsawing and top tech tie wrap lol,all expertly filmed as usual mitch 👍👍

I get great enjoyment following your channel. Look forward to your next instalment.

I use those isolation mounts for all kinds of stuff. I love them. Great job on the worlds best Tiger Cub. Those cases, I mean come on!

Hi Paul i am happy to see you getting better keep up the good work you do

that horn mounting is very classic. My '54 AJS 18S mounts the horn to the left of the battery (on the same side!) in exactly the same orientation, so you're in good company here =)

I love Brazing it's almost like soldering on a grander scale. and a lot easier then just gas welding.

Hello Paul.... no we dont know that the hole for M6 is 5mm... becouse is 4.8 🙂. I will share here a thing that I learn from a old guy: To find what is the hole to tapp for a metric screw... you just multiply the metric size of the screw with 8 and divide by 10. Basicaly, for M6 is 6x8= 48... divide by 10 is 4.8. It works up to M10 screwes. Nice way... right?

Paul I am sure you already know BSA and Triumph bikes were notorious for oil leaks most of my mates bikes back in the day were really crusty. My two strokes [JAP/Villiers] were normally much cleaner.

What is the new red e bike behind the lathe?? Is that part of your recovery? Would love a Paul Brodie bike review on a new mountain bike!

Good vidio Thanks

Perfect :)👍

Paul I tap in my drill pressing by hand turning chuck. I’m looking for a replacement petcock for a Harley Davidson Sprint 350 (Aermacchi ??) Do you have a source for new or gently used. I hope all is well regarding your health? Your content and sharing of knowledge and techniques are not lost on this 64 year old bike fanatic mechanical engineer.

Paul, You almost always go to the bandsaw to cut your turned parts from the material blank. I'm curious why you don't use a parting tool for these details? I know they tend to chatter a bit and you need to reduce the RPMS. Are these the only reasons?

I can imagine that you will only use the original Thomas and Betts zapstraps. Once I found a source for these I have to be desperate to use any similar product.

Another great video. Why didn't you use a thinner piece of aluminum for the back part of the battery (the one you milled out). Was it for strength?

What Alan does with a hacksaw is remarkable. I always wonder why he isn't machining. i have seen him make four cylinder 125 CC engines, v engines, simply remarkable. HE cuts bottom ends in half with a hack saw and welds them and the engines actually run.

This came just in a nick of time! Paul, I have the C15 in my garage and I am now planning what I am going to do with it. Is it possible to send me couple pics of your Tiger Cub? And don't worry - no matter how well you rebuild them, they still leak 🇬🇧

I am confident the zip ties are a joke. I believe a number of you have been had by Mr. Brodie's sense of humour.

In that moment, when you soldered the part, i thought: This has to be nickel plated on the Tiger Cub.

living on the South East coast of England cannot imagine what a nuisance having 'Beavers in your backyard' is like .The best we can do is Moles on your lawn ?

Old brit bikes are like dogs! They mark their territory! So it must feel at home, where it is now.

STRAIGHT TAPPER

Sickkkk

Do you think the point loading from the round lower battery support may cause the case to eventually crack? Would a rubber faced flat plater be better? I always enjoy your vids, Thanks.

😎👍
