Of course while I was powdercoating I also did a final blast of the rear subframe (that I restored on the previous page) and also treated that to a coat of finest black to draw a line under that job so it can be put it away in a box for when this bike is eventually built. This came out pretty well for OEM parts from a couple of units cleaned up and welded together I think. Thanks again to all who contacted me and helped with parts for this bike, its great to be using the parts that otherwise wouldnt have got used. The eagle eyed will notice but the PC isnt perfect on this one in a few places, but tis fine and most wouldnt notice - especially when fitted. I am a bit of a perfectionist as im sure you know lol My excuse is that its really hard to do larger parts like this in the silly oven we are using now. Small ovens have hot and less hot surfaces and space is tight with large parts and its hard to get even heat but also get the part into the oven and suspended on a hook and stop it rotating and touching anything as the PC is marked or rubbed off, this depends on when it happens, ie putting in or pulling it out when cooked. Small parts are easy and this is about as big as you can do, tho i have done F and 500 birdcages and center stands but doing those in a small over is like becoming a master at shibari (I looked it up lol), ie its not easy and takes years to master with consequences if you get it wrong lol. In simple terms, bear in mind that manoeuvring something large in/out of a small oven one handed thats covered in molten powdercoat using extra long pliers by lifting a hook off a bar when everything is at 200degC is a bit nerve wracking lol As an aside with doing this work over the past 5+ years, Ive become a bit of an expert in domestic ovens lol. The one we currently use is a SMEG extra wide unit and its on its side so we can get the drop, but really it'd be better flat and more effort made in suspending parts, not least for its internal temp readings... plus oven doors are spring loaded to work with gravity, standing them on their sides messes with that and means one hand is needed to steady the door for best results... We have this oven cos someone (not me lol!) dropped a brake big caliper through the open glass door of the old faithful 600mm unit and they replaced it with this fancy unit. I do believe they thought they were doing a good thing, but the inside of this oven is too small to be as useful as the old cheapie was. modern ovens do have a lot of insulation so heat up faster, but this has come at the cost of less internal space. And it has to be said for an exy unit its temp also varies terribly, tho thats not helped by the orientation of course. We use a thermocouple to view the actual temp (ovens are notorious for drifting up n down and poor switching) and with this one its a bit of a dance to keep the temp somewhat constant around 200degC for the required 10mins lol. We do also have a massive kiln from the local art college as well... but the cost to run it is scary and was why they got rid of it lol. We used it for wheels years ago but its rarely used these days. Thats a little bit of an insight into some parts of a 'domestic-ish' PC setup I guess, tho there is much more to it from parts washing, blasting, a home made (based on a 205L drum) coating cabinet with vacuum suction and of course a coating machine - the one we have now has a swirl pot etc, tho i tend not to use most of its features lol. Looking back we've come a long way. We started small with a cheap oven from the local scratch and dent place and an ebay gun and now have a lot more kit lol. DIY PC isnt as simple as dropping off parts to a pro and much more time consuming, but it can be rewarding of course. It is much cheaper in many ways tho, while not in oven electricity use lol. ie powder is about 20quid a kg, cheaper if you buy in bulk. 1kg of powder would do a hell of a lot of parts, multiple frames etc. Plus, you can also do the things no pro would want to be bothered with as Ive mentioned before. Anyway, enough about powder for now... I need to get back to that sidestand when the linisher belts arrive...

Good result there
I fancy a bit of diy powder myself once I get a suitable set up built

Thanks Steve.
You can defo do a lot with a cheap ebay gun kit and an oven from the local discount store once you have a compressor.
Surprised no one commented on the linisher belt to be honest lol

Linisher belt is fecked lol but good you have found a replacement
Got a compressor now hence me doing a bit of ceramic coating but need to build a suitable place to do it all
Plan A and B in my head just now so time will tell 🤐

A : A linisher turns a belt or disc of abrasive material to smooth a workpiece, creating a level, even surface. It can also be used to polish materials. Materials are usually wood or metal but, can be plastic also.

I'd advise to keep it away from other machines and finished bike parts etc.

Could not find a description for a LINISHER but did find these: WIRE WHEEL : Cleans paint off bolts and then throws them somewhere under the workbench with the speed of light. Also removes fingerprints and hard-earned calluses from fingers in about the time it takes you to say, 'Oh sh*t' BELT SANDER : An electric sanding tool commonly used to convert minor touch-up jobs into major refinishing jobs.

Haha, my own personal definition of a linisher should be : "A machine that when its belt breaks it whips you like a robot wielding a cat of 9 tails. You wont/cant move fast enough to escape its tentacles and the abrasive material will remove any skin from face, chest, should, arm that it contacts... over and over at 20,000 rpm." Always wear safety equipment with a pro version, my little home one not so much... but it pays to be careful. I assume the belts for this are sill coming... nothing in my post box as yet

I have recently suffered enjoyed another birthday… Im not enjoying the increase in years but I did also receive gifts… some very good ones, see below: I’ll put up a quote for you… you might well know the feeling of this one: “Just when you think you can’t find something and you’re prepared to give up or started a project to make your own, a mate will pop up with something you need…”
JonW 2023 Suffice to say; I love my 2T brothers, here and abroad. They are always amazing. Seriously. Recently I was asked by a mate to come look at a bike he wanted to buy. Yep all good, I’ll be there for you mate! I’m always happy to help a real mate spend his money lol When he reads that he will laugh, he accuses me of doing this all the time... I’d not seen him for ages as he’s been busy but a while back he offered me some parts for this build, amusingly some of them would be parts that had originally come from me over the past decade of horse trading parts between us. It’s a source of amusement now - I firmly believe that we just store parts for each other lol. hmm.... So, on the appointed day, he arrives and opens his car boot to unload before we head off to meet the seller… and promptly pulls things out for me… some of which i knew about, some were a surprise… but, yes, all of it actual “LC gold"… camouflaged as a bunch of rough parts…. and hugely useful to me. WOW! Lets start with this: (looks small in the pics, actually really long of course!) The backstory (told previously on here so please forgive me if you’ve heard it before) is that I bought a pretty rotted out (yet whole) 250LC from a guy a few burbs over from me 7+ years back that was way too far gone to go back on the roads but I stripped it to build up something as lots of the parts were good and a few things like the frame and its engine and some other parts went to my mate and he cut that up for parts and over time people have kept bikes on the road with parts from it. All good, its spirit lived on etc. Now it was my turn to harvest from it. Cool. It doesn’t have everything I need but it’s a great start along with some other brackets other people have sent me. He already sent me a pic (shown before) of the main frame chunk and I knew i was closer to having all the brackets i needed, but he also found me another chunk of it… yep a side stand bracket! ….and also a centre stand! (sadly this matches the driveway a bit too well... rust is a great camo I guess for some of my land... worrying...) Yep, these all look very rusty… SUPERB! Had they been nice, they would have been used long ago. Rust and damage means they got stored and are now on offer to help complete this bike. Their time has come. More on these restoration of these parts in due course...

Still no belts for the linisher... hmm... gotta love international post I guess :/ Ive not been idle… Ive been trying to get powder coat off one of the wheels I was given for this project… more on that later… in the meantime I’ll continue to work on the other parts I was given the other week... The side stand bracket was a surprise, I had no idea he still had it. What a fantastic thing to bring me. Thanks mate! Of course, I’d started to make my own side stand bracket after reading the french forum guys attempt at it. EDITED : Added the link to that site for completeness : yamaha-rd.forumactif.org/t779-fabrication-support-bequille-lateralesBut... I didn’t want to do it the way he did, ie laminating steel together. So I started with 8mm thick plate. I’d got quite a bit of the way down the track, I only needed to do one bend and a bit more profiling of the shape and then weld the parts together and it would be done, but this is of course much much better. What is interesting to note is that the side stand wasn’t fully welded from the factory. This is totally OEM and it never failed, plus it’s easier to cut off i guess. lol Anyway… a gently grinding and we have something ready for cleaning up and here it is after rust removal and the rough edges dressed back, alongside the two parts for the one i had started to make.

What a great thing to have a go at. I understand bending the thick steel without it cracking is the biggest problem, but it looks like you'll be welding the front section on rather than trying to bend it?

I will finish this at some point, but since I now have this original one I'll probably use that when I dod the build. I'll cut the back of the curved part, bend and weld. There is a lot of room in that area for weld and its hidden so not a worry. Yes, the front section would be welded on. But... as said, this is something for later. ie post this build. I'll use the OEM bracket when i build the bike.

Great stuff Jon. Wouldn't the metal bend easier after copious amounts of heat? Anvil, Blacksmith etc lol.

Alex Quite possibly, but I dont have access to a forge... not right now anyway, but who knows when I do eventually finish it. Everyone I spoke to suggested cutting and welding was the way due to size etc Anyway... worry not about the home made bracket... I have the OEM one now

Finally! The linisher belt arrived from China! old and new compared below... how on earth did the old one keep going? Fitting it was 'fun'... brand new belt didnt want to be flexible enough at first, but we got there in the end. Also cleaned up and modded the housing so the badly made (punched through) screw holes dont cut into the belt and will tape it on rather than use the screws just to be sure. Ahh... cheap junk for sure... but it did work for a decade plus like that of course. Pressed it into use right away, oh how Ive missed this very useful tool.

Another report in this occasional series of 'Shit into Shape'... (I'll trademark that as my new TV Series... that or use it on OnlyFans... er, moving on...) Ive not been completely idle on this project... Ive been spending money... I bought a set of the "SuzukiExpert" center stand brackets. Here is their pic of them: As I said elsewhere : I thought it a bit penny pinching from the seller of the brackets not to include the C/Spring pin with the brackets at this price point (£45+£5 post in the UK). After all, every single person who buys these brackets will be wanting one of those pins (and having to make one so needing dimensions etc) and wondering exactly where it fits (could it be in the hole in the bracket, maybe?)... thats quite a few people all doing the same task and needing pins making... That's the last I'll say on that. I'll make a pin (I have a lathe) and sort it. --- Well talking of Centre Stands... Mine is pretty ugly as we know, pic from above: But Ive been working on it... Ive cleaned off the rust and started to cut out the 'broken and then poorly repaired foot bar'. Wow that was a nasty repair different sized steel tubes overlaid with chicken shit welding. Someone should take that guy's tools away and never let them have it back. Proof, were it needed tho that these were dirt cheap farm bikes not that long ago lol Obviously Ive still a way to go, but this is where I am until I get the powerfile and welder out... but I was waiting until I had the next stage ready, may as well sort this in one go and do all the repairs etc. I will say that the original bar was very well welded into place, no wonder these are strong and the ends break off rather than the whole thing coming apart. I should add... This is a bit of work, but Im not complaining. A good mate gave me this as a gift. It actually came off a (most of a) bike that I sold him many years ago. The frame was too rotten to go back on the road but we both scored a load of parts off it and he had never bothered to try and repair the stand... back then I didnt even notice it had one on it when it sold it to him... well, I did say it was a lot of years ago lol

In order to 'find a foot', I set about trying to find something Yamaha from the era with a similar stand... lots of options, some cheap too... I would have made one, but its a randomly bent bit of tube and the foot end would be nicer if it was OEM etc. I figured something must have been similar. A few forum guys and I discussed this at some length and they had some other good ideas, but I needed to find something local due to the cost of sending through the post/ In the end I settled on the glorious(!?) XJ750 SECA... well, in my defence it looked pretty close if not actually 'pretty'... and it was cheap enough at under 20quid (sellers pics) So how does it compare? Well pretty good. A bit short and a bit stronger perhaps... defo a good basis for what I need I think.

Great work!
It also has serrations to stop your foot slipping off 😎 I've done a similar exercise with the back brake pedal. I'm sure I could make the actual lever but the part you actually press down on would be a lot of work to get anything like. I found that a lot of Yams use similar parts but often with cast steel for the rest of the pedal. I think it was an XS400 one I bought for about £20. It's in the 'might get around to it sometime' pile.
By the way. Citric acid is a good way to de-rust this kind of part. Dropped my exhaust and swinging arm off my SR125 in my citric acid bath for a week (or maybe two) and the rust is gone. It's labour free 😁

Yes, my thinking too Steve.
I used DeoxC, but then left it sitting around after in a damp enviroment as its been so humid. I didnt coat it as I am going to blast it before powder coating it later so not too worried. The bad rust will be cut out and the edges blasted before welding too.

I'm almost convinced De-oxC is just citric acid but more expensive, almost. I'm tempted to drop one of the frames in my big tub, it's the old water storage tank from my lads house. I'm a bit concerned about the fluid ending up and staying inside the tubes although I dropped the SR125 swinger in there and it did a good job. If I was to do it I'd do it when it was warm.and sunny. In this country that narrows it down to 2 or 3 days a year 😎

I dont think id want to leave anything liquid in a frame, but they usually have drain holes as bikes get ridden/parked in the rain etc.

It wasn't really bad, just enough rust in there for the dust to come through and disrupt the carburation. It would stop it revving out on the park Straight at Cadwell then gradually improve on the twisties as the fuel demand was lower. Then it would be OK on the next straight before not revving on Park again. Blooming frustrating. I left it overnight with the DeoxC in If I remember right and poured it out in the morning and rinsed it. It was such a warm sunny day and the black tank was so warm it dried within seconds really. I have an unused tub of DeoxC so I could do a back-to-back experiment if I was an organised logical person
