Nice work Clint, cominga long real nice :thumb:

are you going to make the fairing to match?







I can hardly believe I took this picture back in 2013, where does the time go?

I'm not sure.  We were talking about it today.  Fairings on a bike in a small shop are a drag, but i do like the fairing.  will probably make one eventually.  There are a lot of other things needing address first.

Edit- I didn't realize those were YOUR pictures, Jim.  Thank you for taking them and letting them get out into the Internet realm. They have been a significant resource for this project.

I hope you can make the fairing one day, it would be great.

I kick myself for not taking many, many more pictures of the museum bikes, I took a lot of pictures of the V7 Sport because that was the bike I was restoring at the time but I sure wish I had taken a couple hundred pictures of the various bacon slicers and race bikes, I need to get back to Italy and the Guzzi museum, hopefuly next year....

What I've learned doing this tank is that some of the  organic shapes that are so quintessentially Italian are not necessarily a deliberately composed design.  They are simply a natural action-reaction function of the metal as it is hammered, stretched and shaped in certain areas and left alone in other areas. 

The side of those original Record bike tanks got the majority of their "flow" by how they were stretched at top and bottom while the center area was left alone in whole or part.   I was tempted to leave them that way and not add the more pronounced concave detail.  But they were in strong tension, which is not good for installation.  Adding the deliberate concave detail relieved that tension and looks like the Ducati Americano tanks l like so much.  The Record bikes were built for such limited use, they only had to survive for a few days of use.  Mine will hopefully get more,use than that.

I'm really enjoying the Metalshaping.  My original plan was to do this level of special bodywork for my V7 Sport, simply because I had it.   Simply bolt-on stuff,  but use it as a canvas for new shapes.  Then this loop chunk showed up cheap, I discovered the Record bikes and it was time for a new plan.

Thanks, Rick.   Hopefully it will help others make parts they want for their bikes.

The original bikes used a cheap generic Italian flip-up gas cap.  They were also used on some of the MV Augusta singles. Repro versions available now as ultra lightweight racing fuel cap are slightly different (both cap and base ring), but I was able to source an original cap. 

For the filler neck. I folded a double thickness of aluminum with extra length for the neck, rolled it into a tube and filed it to fit inside the base ring.  After it was ready, I marked the tank and made a hole with a knock-out punch.





To install the filler neck, I turned a flange on the hole in the tank.  I started with a simple slotted tipping tool before working the flange into final shape with hammer and dolly.  The more refined way to make one is with a flaring or belling die set.  Without a flange, welding is much more difficult and the tank is likely to distort when the weld cools.  The lip created by the folded double thickness provide the necessary arrangement for a butt weld between flange & filler neck.









All was welded together. I welded the filler neck with oxy/hyd.  No issues, no problems.  Tried welding filler neck to tank with oxy/hyd and still need to learn how to do larger pieces....  So I used my oxy/act torch and had the weld done in a couple of minutes.









The filler neck is long to allow trimming if needed.  This old cap came with the original shrunken, hardened rubber cap gasket.  Until that gasket has been replaced with ??, I don't know how tall or short it needs to be.

Well, resolving the welds on this tank IS a lot faster & easier with oxy/act.... 

I've been filing and planishing a little and fixing the holes.  With more work, I'm sure I could make it perfectly straight and smooth but that isn't how the original tanks were finished.   It's clear from the pics they are not perfect.  After all is done and it's painted with primer, this tank should look pretty close to those tanks.

Those MG Museum pics you've sent have already helped, Jim.  Among other things, I've been able to see the rear fender mounts to battery tray were riveted to the fender.  That's been a blurry detail in every pic to date.  So I'll be correcting that shortly.  Thanks, man.

i don't have the material for bungs or related parts here yet for the tank, so I made a little progress on the frame. 

The rear hoop of the frame has been cut like the original bikes.  The frame tubes needed to be capped and exhaust hangers needed to be made & installed.

Based upon Jim's museum pics, the original hangers appear to be made of two pieces, laminated together to provide some wrap around the frame rail for better integrity.  I made mine a little longer on the outside, figuring they will have to last longer than a few days of use.

Caps and hangers-

Thanks, Chad.  One of these days, it'll get done.  In the meantime, a little more progress ....

The original exhaust nuts in the engine aren't perfect, but they're not half destroyed by channel lock pliers like the ones that came on (and are still on) my V7 Sport.  They didn't easily budge with a wooden drift.  So for the last however long, I've been keeping them wetted with ATF.   There isn't an exhaust wrench in my G5 Guzzi tool kit on the sport.  Nothing else in the tool boxes here fit particularly well.  And those cool exhaust wrenches on eBay cost $$$. 

So while Elsmore observed the other day, I made a quick rubbed paper pattern of the installed nut.  Glued it to a handy piece of scrap metal.  About an hour of Hole sawing, bandsawing/hack sawing and some filing later, it fits pretty good and works even better. 













Both nuts came loose with no trouble or damage.  Threads in heads are great.  Very cool and Elsmore was thoroughly entertained by the effort.    but I finally lost a long-suffering tire on the bandsaw at the beginning of this project.  Once that's replaced,  I'll pretty up the wrench with rounded corners and a nicer handle

Nice job fabricating that exhaust nut wrench! Far more satisfying than just plugging in your MasterCard and ordering one.
I need to make one just like that for my Moto Morini 500 and hadnít figured out how to make it.

It's very low tech...  That's why Elsmore stood around and watched.  He said he wanted to see this work.

A piece of scrap paper is marked on the end of the pipe.





The marked circle is trimmed and opened in one side to easily fit over pipe.  Then it is installed against the exhaust nut and rubbed with a dirty finger to define the pattern.









Now the pattern & blank are nearly ready for a quick squirt of 3M 77 upholstery adhesive.   Trimming the pattern with a razor blade after gluing it to the blank helps assure the tabs will properly aligned and not torn.





Before I glued up pattern & blank when I made my wrench, I used a slightly undersized 1 3/4" hole saw on my drill press to open the center close the needed approx 1 7/8" diameter..  That made it easier to roughly align the pattern to the blank.  After that, it was a matter of sawing and filing away what wasn't needed.

I tried to keep the end tabs very tight and work the other tabs away from the center point.  Its also important to keep checking the fit from both faces of the wrench to make sure the tabs are even & square.  It's a little tedious but worth it to get a tight fit.  And to show Elsmore how to do something new...

As my lathe skills for making bungs for the tank develop, I got a sheet of 18g crs for bike and car stuff.  I need a slip roll to make the exhaust components.  Using materials collected for other machines, I made a very low $$ version of a slip roll.

About a foot of angle iron was cut, trimmed and welded to make both fulcrum and adjustable ends.  Fulcrum end needs a little shim work but that's simple.









The adjustable end has top retainers with a simple welded nut adjuster to allow the lower two bars to spread to form a taper.









Screwed to an oak board, all is good-





Metal isn't formed by rolling.  The longer top bar is pressed down as the metal is progressively moved to produce an even bend.   Using a piece of scrap that wasn't trimmed, it quickly became a nice smooth rolled piece of aluminum.  Very cool.













I wouldn't want to go into production using my slip roll bender, but it works great.  Making one with three pieces of plain iron or black pipe, some scrap lumber and screws would probably work just as well and be even cheaper.  For a machine that may not be used much, it's another low $$ option.

there's multiple ways to produce the patterns for tapered cones.  I hate doing lots of math, so I used the wooden patterns of the reverse cone megaphones that I made (scaled up from pics of the original bikes) with paper, tape, ruler and sharp knife to do the patterns for the metal blanks.

Paper was taped to the wooden patterns, then tightly wrapped & overlapped before being taped to itself.  the ends of the taper were trimmed with a sharp knife.   A straight edge was taped to the overlapped paper.   A cut along the straight edge produces nice long edges as it releases the paper from the wooden pattern.  lots easier that trying to lay out and produce perfect precise radii cuts...









With collector, main taper and reverse taper, there are three patterns in total.
