The bike looks standard until you do a double take and spot all the subtle mods. Keep it up Al, she's a great bike.

Hi all A bit more playing with the project this morning Did a quick design on the pc and printed out my possible layout for my master cylinder operating arm It retains the original brake pedal mount / pivot unit and is just a double arm to convert the rotary movement into a linear movement required for the master cylinder operation. Also the master cylinder arm will have a series of holes in the master cylinder mounting arm side so you can adjust the ratio of pedal movement to master cylinder movement[emoji106] Lastly as I am using the original brake pedal pivot unit, I will also solve my brake light switch set up as it will be as original Now off to design for now a simple back plate that bolts to the Raask rear-set mount so I can dummy up the full assembly and once happily I can tidy up the design so it looks pleasing to the eye and then crack on with the final parts again in aluminium Happy days Catch up soon Best wishes Al Sent from my iPhone using Tapatalk

Quick update Had a go at designing / testing out the master cylinder mount concept this evening Not bad for a first try Need to increase the cylinder movement but this should be a simple case of adjusting the hole position for both the original rearsets mount and the master cylinder mounting position and rotate the master cylinder accordingly but in essence the idea looks ok and no modifications required to the original rearsets Really made some progress this weekend Best wishes and have a good week all Al Sent from my iPhone using Tapatalk

Evening all Had a play with the master cylinder set up an now not a million miles away[emoji16] Ratio is much better and this is a video of the full master cylinder movement verses pedal which in theory will be less with fluid in the system Also looks less like a mecanno part and more refined in shape and looks and now has added a remote fluid reservoir Think the next stage is to get a custom hose made from Venhill so I can temporarily fill the system and just see what the final pedal movement is and hopefully the master cylinder suitable or is I need to source a different bore size and if it feels ok as just a bench test I will commit to aluminium parts that will be anodised black so the set up blends in with the Raask mounting plate Catch up again soon and best wishes Al Sent from my iPhone using Tapatalk

wow, superb work Al as ever.
Loving the Raasks too... you should find a 5 year old to sand cast these new parts to keep the quality of the parts even across the foot controls haha.
(I joke about the Raasks, but you all know I love them dearly as I have more than a few sets on my bikes:) really its the LC's footrest plates that were the worst made, the foot rests and pedals were actually really nice as can be seen in the pics and Als look new!)

Hi Jon Yes I know what you mean about the Raask units but better than the old rubber Honda foot pegs🤮 My only criticism is they need to come supplied with 10 free Yoga sessions as the foot position being quite high is a bit radical for a 53 yer old😁😁 Best wishes Al

The rear sets just add to that period look Al. Just do a bit of gentle stretching before you go for a ride lol.

You laugh but got physio tomorrow as got a possible slipped disc at the mo (bugger)
Lost all sensation in my R/h leg due they think to the disc compressing some nerves in my spine☹️
Walking fine but just pain in my backside and deep in my thigh

Hi Alex
Yes I am ok
It’s more the strange lost feeling in the leg and it’s also strange but more comfortable moving about doing stuff than sat down at a desk or standing still🤔
Part of getting older and there is a saying that says
“Alway appreciated your age and don’t moan about it as there’s are many people that never had the chance to get to your age”
Especially poignant soon as it will soon be remembrance Sunday
“God bless them all that gave their todays so that we may have our tomorrow’s”
Al

Ok to cheer myself up due to a fooked back at the moment just bought this (after a chat to the real “boss”) as a early Xmas prezzy for the CB400F rear disc conversion project An original Dresda box section rear swing arm😎 Will need a bit of TLC but another non standard part[emoji16][emoji16] for the old girl and will blend in nicely with the rear disc conversion Only problem is this bike modification process has now started to become an obsession [emoji17][emoji17] Also now got my hose from Venhill so should be able to test fit this too to see if I got my hose length right Catch up again soon and all have a good week Best wishes and ride safe Al Sent from my iPhone using Tapatalk

Hi Alex
Lucky spot (I think😂😂) on flea bay after reading a classic bike mag this afternoon that my son had kindly bought me , and seeing a CB400F fitted with one
Been looking for a while off and on, but I think the one designed to fit the CB400F are more rarer than rocking horse 💩
It needs some TLC but should look trick with the rear disc conversion (I hope)
Also wrote to Dresda Engineering to see if I can get some original decals after its been powder coated🤞
Catch up soon
Best wishes Al

That's brilliant! Hopefully they'll send you some decals gratis. Pro Comp did that for me (all the way from the US and free...nice touch).

Gentle ride out could be fun.

Hi all Even with a bitch of a back still managing to do some bits Did a dry fit of the newly acquired Dresda swing-arm today Needed to modify it slightly, as due to it being a box section, the caliper hanger needs to “fit” inside by adding a slot in the bottom as you can see in the following pics Now need to make a different wheel pull for that side due to how I have fitted the hanger inside the box section, but as Baldric would say “sir I got an idea” and yes it is as cunning as a fox😁😁 A bit more of the project sorted Catch up again soon and have a good weekend Al

Morning all Started the design for the disc locker unit First started with a CAD model of what I thought should work Then did a print in ABS Note slots are to clear all internal webs to maintain hub strength Then tried it in the original hub where the four legs locate snuggly in the four pockets between the bonded rubber casting bosses On initial fit it really is a nice snug fit Finally attached to the disc holder and refitted And final fit in the hub Disc locker looks spot on and I think is more than up to the task of stopping disc carrier rotation under braking Still waiting the other parts in their final material and once these are in and fitted will crack on with this final part in aluminium Think that’s all for now Catch up again soon Best wishes Al Sent from my iPhone using Tapatalk

Hi all Quick update Got my first set of parts back from my CNC friend All now fitted and brake bleed Looks the biz and I think I will leave the supplied parts in their bead blasted finish for now All that is left is the disc locker unit and a modified wheel pull for the caliper side ((due to changing the swing arm to a original Dresda unit) that is now in the making and then hopefully when’s that’s all fitted that this “project” done and I can move onto that 460cc engine build[emoji106] Here are the pics Hope you like Best wishes and catch up soon Al Sent from my iPhone using Tapatalk

That looks suspiciously like a Mito caliper to me.
And more fantastic work!

Alex Hi Alex Good spot😎 Yes I am afraid I borrowed it from the Tigcraft bike (including the Honda NSR master cylinder) But as a positive at least I now have found someone to make me a nice CNC caliper holder that fits a Mito caliper and a Honda NSR swingarm😁😁 and Mito calipers at the moment are plentiful and cheap👍 (If I every can get myself away from the little Honda) Also will be off grid soon as got an op planned for the 13 December to try and sort out my back ( Lumber decompression or when on the table if not viable fuse two vertebrae together😔 Take it easy and I will be the first on the forum to say merry Xmas to all 😁😁 oh fook I can already here all the “Barr humbug”comments Best wishes to you all Al

Hi all. A quiet time while recovering for my back operation. But my buddy has finished my “disc locker” unit in aluminium that both bolts to the disc carrier and will also fit the internal features of the original wheel hub to “lock”the disc to the main wheel hub under braking. Here is the 3d printed test part fitted to my finished disc carrier It a fair piece of aluminium and the 4 legs lock into / fit in the pockets left by the bosses that are for the cush drive bonded bush’s and the slots on the disc locker miss all the internal hub webs so no side loading is applied to these areas under braking. Don’t see anything going anywhere and certainly over engineered for its purpose but that’s the way I like it[emoji106] Just need to sit back now for a few weeks so my back can fully recover and then I can finish of the assembly and job all done. Catch up soon. Best wishes Al. Sent from my iPhone using Tapatalk
