thank you so much! Very clear excellent video helped me to replace the bayonet.

Thanks for the video but why did not you add a video for frame slide for this bike ??

Nice bit of stop motion

Nice work and a great set of vidoes. Thanks for taking the time to share your work with us. I'm thinking about doing something similar, but using one piece of 50mm thick plate instead of bolting two bits of 25mm plate together. I don't have a mill so I wont be able to trim the plate to size like you did, so I'll probably have to live with some overhang on one side...

You don't know how much this helped me with a biped robot. Was using a rod to transfer motion but had only used two wheels, added a 3rd and now it works great.

Thnx ⚡️

😢interesting and useful information for the new starts in model engineering. However we should also show safe practice. You should never use a finger to set a wiggles. Always use the side of a pencil etc and not something that will bleed!

Do you have a video of your crash slider install?

Is there a reason castings are used? There desn't seem to be a lot of metal removed, plus you have an increased chance of voids and crystal boundary failures, and all the other downsides associated with castings.

what a beautiful video i will use this to spin my gears rather than using pulleys its both cheaper and effitient thanks so much mark 🙏

Are these spheres on the rods one piece or how did you attach then together? Are they welded? Thanks for the video

You can get an adjustable 3 jaw chuck which would be more accurate but they're the same price as the lathe new

i bought an old stanley no 4 1/2 plane off ebay and it had a great looking patina . but befor the guy sent it to me he we nt mad with a sander and destroyed the finish he thought he was doing me a favour . so i was looking for a way to finish the plane and it looks like i have found it . thank you so much for your post

fyi, working on a lathe with gloves on is a no-no. Don't try this at home...

I've just 'binged' these videos for your top yoke and thoroughly enjoyed them. I've been an engineer for longer than I care to remember but always learn something new watching others. Great job indeed and thanks for videoing the project and making it available. Cheers Grahame 🙂

Thanks piece of mind and reassurance for me when doing mine. Thanks again, very clear explanation I doing the job

Personally, I make metric parts on metric bikes and Imperial parts on bikes made in inches. Guess I'm OCD but it drives me crazy when people start fitting 'wrong' threads and sizes. Some older Honda's (mid 60's~70's) actually used Whitworth thread on spokes, bit of a shock finding 1/8" Whitworth thread on a 'modern' bike. I had a couple of V-50's and a V-75 several years ago, liked them simply because they are 'different'

Hi all. Watched a alot of videos on the bmw 1000 range bikes. I see on the rear sprockets that some have the flat side facing out and some have the liped side facing out. Is ther a right way or wrong way the have the rear sprocket facing,?

Parafin, all you need for chain cleaning. Cheap and cuts grease and all the shite off...rinse, dry the chain and relube

What brand of torque tool is that

Nice technique. Considering making one of these for mine. Would you say ER40 is a suitable size? I guess that gives you a lot of options on what it can hold.

nice vid .crap uneccessary music

Very detailed and clear video. Thanks for posting.

Absolutely loving your videos on ‘Jack’ brilliant. Thank you.

Very good video.

This was a major peeve of mine when the Thomas series went CGI, the wheels were not quartered they always were equal. I know it is a kid show but it got me into trains, especially steam and that just was my "Rivet counter" peeve. Sure you understand

Pretty sure that backplate of the lathe is a short taper. Did you check that?

10 nm sounds alot ...

Hi Mark been watching your video on the qctp I have just got the same I wonder if you could remember the diameter and depth of the recess on the underside of the top slide kind regards rex Harrison

Fantastic, well done

This series is the best laid out, most informative and most interesting I’ve watched on you tube. Well done

Nice use of the wobbler here!

Absolutely lovely 👍👍👍

The phone mount seems rather high. Does it still allow you to tuck in behind the windscreen when the phone is mounted?

Thanks for posting. I'm looking at buying a set of warmers and had seen the Oxford product as an option. This has been very useful to watch! 👍👍.

Really good series, Mark, thank you for posting all the videos, I have finally caught up. You have intrigued me with the floating ball on the steam brake cylinder drain valve - that's going to require a material than can take temperatures of >160C, that's less dense than water, and that is supplied as a sphere (or you have to make a tiny sphere somehow, no easy thing). What material meets the requirement? Or I suppose a hollow sphere made of pretty much anything would float, but are these available?

Hi Mark. So good to see you went back to the original design for the Guzzi one of the best bikes ever made. nice work on the hangers.

Really interesting 😀 I treated myself to a scroll type four jaw chuck which is handy for square stock.

Yay! Good to see you back!

That loco will be very nice when all is done! I shall continue to watch your channel on a regular basis. Thanks

I may be missing something around the 15:00 mark. Why use the wiggler to center find and not just a needle pin chucked up?

I watched the entire series with interest. There are some things that I would have approached differently, but there is no right or wrong way, just the way that suits you best. I would not have used 6082 grade for this however. It will probably be perfectly ok but a tougher grade would have been my choice, even though it would be more expensive. Thank you.

Just come across these brill vids. Am building LBSC's Mona in 3 1/2ins guage (recently re-started after a very long lay-off). Although a smaller gauge the build principles are much the same and are proving invaluable to a novice like myself. Many thanks.

Another often overlooked step is removing the front sprocket cover and cleaning away all the accumulated wax/lube and road debris. Only takes a few minutes and if you’ve never done it you will be surprised how much gunk is in there. Kerosene is all you need for cleaning the chain and sprocket area, then finish with a light coating of Maxima Chain Wax.

Hi Mark, please can you let me know what you are using to record your lap times. Thanks, Chris

chain sag needs to be measured with the bike on the sidestand

people think that imperial is in fractions... it is not. One inch is split up into 1000 or 10000's of an inch... where is the fraction? only woodworkers use fractions. Thus imperial is no different from the French system. And don't get me started on that! I do not know why anyone would use a system metered out ( pun intended) by two of the most incompetent surveyors that France ever produced.

I will challenge the wisdom of going near any rotating part using your fingers. Two other content providers both use 1000rpm spin speed and a pen/pencil to stabilise the wiggler. I always use eye protection on my mill and lathe. Maybe for this a full shield (which I do wear on occasions) is also an idea. A wiggler spinning off into your face would be very nasty.

At 22:12 you could have pushed Y-1/2 and your Y center would have been at 0 …

Thank you . Very clear , well paced video . 👍
