Had a productive afternoon roughing out the new steering stem to within about 1mm of desired diameter.
The old lathe took a bit of fettling to stop the chattering, and I was cutting it a bit slowly to start with.
Now the slow and time consuming part as clearances will need to be spot on.

Well it's getting a little more exciting, now just need to make a spacer for below the bottom bearing and all will be ready to fit the DR600 front end on. Took a little bit to sort this out and I must thank my friend Malcolm, a retired toolmaker for his help with this. I have so much to learn when it comes to machining. Having a great mentor is always a big advantage. If I may offer advice, just keep asking lots of questions, 'cause the skills of these old tradesmen are disappearing these days.

Again Im sorry about the poor phone pics, Canon camera has died
Well I got the forks on and then jacked the bike up and sat the swingarm in for a check and look and see.
Realy quite impressed how it is coming together. The swingarm is too long and I have been given another swing arm by JonW, which looks like it will fit the bill nicely.
I will try to take some decnt pics over the weekend, as I look at ways to get the rear suspension working.

I didnt get mirrors with the bike, sorry. I have one but it is cracked
Below are some better pictures taken in daylight.
I decided to re-fit the exhaust and foot peg carriers to check for clearances. Things are pretty tight in there and on the upside, with the extended and twisted DR600 swingarm sitting in there its too wide and hits the mufflers on both sides. Sort of eases the frustration of the fabricator.
Measure 6 times cut once.
Like I said above, Once I get the other RGV250 Mk1 swingarm and see if I can make it work in there. I will then be working out how to get the rear suspension to operate, but may just dump the linkages and go a straight shock. Fabricating a new trop shock mount.
Over the next few days I will be making all the fairing brackets to hold the lowers to the frame.
Thios has been an enjoyable day and its coming together nicely!!

One step forward 2 steps back it seems
Well I put the other swingarm in the back of the RG and it is an early RG alright. Same length as the one I have . . . .
I am going to fabricate a new one out of chromoly using the stock ones dimensions and 50mm longer.
Just had a look at the steering head angle and its about 33 degrees on the bike lift. I will have to lift the back end a bit and feed the forks through the triple a bit to compensate.

I now have the bushes made and the swing arm in, now adjusting the clearances. The lower shock mount was hitting the chambers underneath, as were the mufflers. However whilst contemplating I losened the foot peg carriers and with 2mm spacers each side i will get my clearance. Once this has been done I will shorten the swingarm about 50mm.
I have better get busy as I now have some competition, 4 stroke competition, Steel frame competition
Kansas Charlie has started his Scrapper build
Introducing the FZWHY250, what you get when you cross a TM250 with an FZR250, long way to go, but looks like it will be a fun ride

The Joys of building Scrappers
Today has been a bit of a set back. Or a lot of a set back . . . . Im not giving up . . . . yet
My mantra has been to build a bike that wont destroy the donor bike.
The two photos below tell the story . . . .
I need to lift the bike, quite a bit actually, to fit on it
BUT . . . the countershaft sprocket is 150mm (6in) in front of the swingarm pivot, so as the chain needs to bend around the pivot when the bike is lifted it creates a big problem.
I can run an idler pulley, but there isnt a lot of room for that. Its pretty tight in there. Still contemplating this . . . .
Also I really need to lower the swingarm pivot abour 40mm to make it work. Then the wheel offset to the counteshaft sproket needs to be lined up as it will be out by 10mm
I will need to find another RG frame and hack the living daylights out of it . . . . anyone know where I could possibe find one, cheap?
Now in this image the swingarm is not sitting where it needs to be . . . its hanging on the pivot bolt . . .

After a little contemplating today . . . . .
It will work out ok, now to get the new swingarm built 50mm longer than this one

The chain runs from the top of the front spocket to the top of the rear sprocket, and of course the rear sprocket is relatively large, so your chain run shouln't put that much tension in to the top of the swingarm at the pivot... Having thought about it, is that why you're happier now?
Just wanted you to knwo we're reading the posts and interested in what you're doing... _________________ Light is right. |
