seat shell and this will help if I need to re-do it soon. I do not think it will move. It looks good. Perhaps<br />

next time I will get it done professionally.<br />

#1714 To sculpt foam when upholstering seats etc. use an electric carving knife. Borrow one from wife<br />

or available at car boot sale near you for around £2.00 PS. Buy two if you can cos they tend to fall off<br />

the workbench and smash or be stood upon when wrestling with seat covers!<br />

L #2019 When refitting the petrol tank today I sheared one of the studs which are used to fasten<br />

the stiffening bar across the front of the tank. In my defense, when I look at it, it has been sheared<br />

sometime in the past and a new stud brazed onto the part still in the tank. It’s the brazing which has<br />

failed today. Is the stud brazed into the tank or is it screwed into a threaded boss which is brazed into<br />

the tank? In other words can I screw out what's left of the stud, make another and screw it in? If the<br />

stud itself is brazed in the tank my current thoughts are to (very carefully) drill into it and tap it say 3mm<br />

(it’s a 1/4 BSF stud) then make a stepped stud, threaded 3mm at one end and 6mm at the other and<br />

screw it into the 3mm tapped hole with Loctite. <strong>The</strong> stiffening bar could then be fitted as normal. I want<br />

to avoid brazing if possible.<br />

#2023 Firstly, I assume you are talking about the 3½ gal tank with round badges and knee grips. <strong>The</strong><br />

stud for the strap is threaded ¼" BSF, but has a 3/8" dia boss to locate the strap, and a larger flange<br />

above that. It is (or was originally) welded (not brazed) to the tank. It is not a separate, plain stud<br />

screwed into anything! I'd recommend cutting the old stub off completely, and turning up a new piece to<br />

be welded in its place. Welding is better than brazing, as brazing can cause local hardening and<br />

subsequent cracking of the sheet metal.<br />

#2024. <strong>The</strong> Velo tank is the one with badges and the studs look exactly as described, so it looks like<br />

welding a new one on is the answer. Tomorrow or Thursday will be the first chance I get so if anyone<br />

has any other suggestions before then, I'd be grateful.<br />

#2025 Easier than welding, but not as permanent, if you make the new stud with a large area base<br />

(tank end), maybe you could solder it in position, or even 'glue' it with Araldite.<br />

L #2113 So I have partially dismantled the Venom that's been in hibernation for 25 years, and its<br />

going quite well everything looks good, except for minor scratching to the piston (bore is ok). 25 year<br />

old engine oil actually looked pretty good, which is more than can be said for the chaincase oil which I'd<br />

rather not talk about. <strong>The</strong> questions I have are related to how to finish the bits and pieces I note in<br />

many books there are references to "matt chrome plating" to be used instead of the original cadmium<br />

plating on part such as kick start. What exactly is "matt chrome" and how does the plating process<br />

differ from the regular polished chrome finish. <strong>The</strong> other question is painting cycle parts like primary<br />

covers, oil tank and headlight cowl. I was thinking of powder coat, but now I am having second<br />

thoughts. Which parts should be enameled/cellulose and which pieces powder coated? Any<br />

recommendations? Anybody know of a good powder coat shop in the Bay area?<br />

#2114 Many items were dull/matt/satin chrome in the first place and not cad plated. eg Kick start, steel<br />

gear levers, brake levers, rear brake spindle steady plate, steel rearset brake pedal etc. etc. <strong>The</strong><br />

difference lies in preparation of the material. After polishing or other prep and before plating the part is<br />

gently sand blasted. <strong>The</strong> chrome is not polished after plating. <strong>The</strong> details will doubtless vary depending<br />

on your plater, but that's how it was explained, and done, for me. Painting should be just that. Veloce<br />

dipped their bits in a production facility paint machine. That’s why the original finish is so smooth and<br />

thin. Stove enamel can be applied to give the same (ish) finish. Often its too thickly applied. Same with<br />

powder coat which is after all a plastic skin spread over the part. My opinion is that it all depends on<br />

your requirements. Powder coat for a well used machine eg trials Stove for a tough good finish. Do it<br />

your self for the right effect. This can be sprayed acrylic even brushed if you're really good at it. We<br />

have a paint shop near me that sprays; not stove. <strong>The</strong> finish is excellent. This will not be as tough as<br />

stove though. I would avoid powder coating as the parts look as if they are dipped in or made from<br />

treacle - that's just my personal preference !<br />
