Lovely bit of welding there. Proper skill. Find someone with a lathe big enough to take a wheel Mark. Will make a much truer job of taking those welds back. John

Did you speak to Steve, Mark ? I bet he has the machinery to take the welds back Dusty

Thanks John, and thanks for your suggestion. I'll check with Steve Dusty (Steve is Dusty's engineer that specializes in machining) Thanks Mouse and Sidney81 I've got to make balance pipes and extend the choke for number 3 and 4 cylinders next

Balance pipes The plan is to make 2 balance pipes, and link the two with another flexible pipe. I'm making it all out of copper plumbing fittings, 8,10, and 12mm tube and fittings will be used. I'm aiming for a fairly seamless. I first have to cut the tube and make some internal liners SDC11998 I then cut more pipe for the smaller top tube SDC12000The left balance pipe assembled, ready for soldering SDC12001 And the right after soldering SDC12003 Both pipes soldered and fitted, I used copper washers to act as depth stops SDC12005 And finally with the flexible tube connected. SDC12004 I'll polish the pipes up, and they can go in the pile for bright zinc plating Cheers, Mark

Choke I struggled with the choke a bit. The choke knob for cylinders 3 and 4 will be really hard to get to if not impossible, so I set about extending the choke control. I kicked around a couple of ideas- one was a cable (using a 350R type lever), but I wanted to keep the original look. I decided on a tube and rod linkage made from stainless steel So I cut some SS tube, plates for the brackets and a rod of Silver steel SDC12006 Next, I bent the brackets- they will mount under the intake rubber bolts SDC12007 And the brackets and tube in place. SDC12008 The 2 choke knobs will be stacked, next to each other Cheers, Mark

Choke part 2 I'm using a tube and rod system for the inboard choke. I knew straight away that the rod would vibrate and rattle around in the tube. So I set about making a pair of nylon bushes. First rough pass on the lathe - there will be some of wastage of material SDC12009 Turning down to the final size SDC12010 SDC12011 And in position. The bushes will stop any noise and wear, and give a bit of resistance when the choke is applied SDC12012 Just the knob to attach and make a linkage to the choke mechanism Cheers, Mark

Thanks Shaun Choke part 3 I cut a deep groove in a very nice choke knob . I then made a link plate to slot into the knob. I then threaded the end of the operating rod. Next a stainless steel washer was silver soldered to the rod, this was to clamp the link plate between the washer and a nut on the threaded rod. The support brackets were then silver soldered onto the tube. So this is the extended choke finished SDC12021 SDC12022 That is pretty much the end of fabrication for now, apart from the generator guide wire. It has to be made, as it is in a new position and a different shape to original. Once the wire guide is made, I can get all the parts to the platers, there are loads of parts to be bright zinc plated So I made a wire guide SDC12032 I took some pictures of how I made the guide- let me know if any of you guys are interested in how it was made Cheers, Mark

Hi Mark i couldn't really follow you choke plan until i saw the last picture, then the muddy waters cleared. I think it look visually very imposing. Luv it

Cheers, sbscnor, Tobyjugs, Sydney 81, Yogi, tonyd123 You have no idea how much your comments drive me forward- it is so appreciated as I still struggle to comprehend what has happened in my private life. scscnor, they are easy to make the wire guides- I'm about to do a guide! Tobyjugs- the look I was after, cheers pal Cheers Chris Yogi - thanks mate, I think it's a compliment tonyd123- thanks mate, appreciated

Wire guide, Guide! I made a few wire guides as they can be in with the zinc plating. This is how I made them I first cut a strip of 1.5mm thick steel the same width as the standard wire guides SDC12023 I then grind two parallel slots to fold over the wire SDC12024 I then fold the inner grove in a vice to 90 degrees SDC12025 Next a length of wire coat hanger is clamped by the second fold and soldered SDC12026 Another light score groove is then ground on the outside SDC12027 And then a fold is made the other way, ready for the plate to be drilled and shaped. SDC12028 Once the plate is drilled and shaped, you just have to bend the wire to the shape you want - simples Cheers, Mark (and thanks lads for all the "push forwards")
