Thanks!
As I said before, as popular as Goldies are, there is relatively little, actual and usable restoration information online. By documenting my build it will help others on their builds.

Oh look, a REAL cafe racer! Looks incredible and great pictures to go along with a great build. Can't wait to see it running and riding!!!

Thanks guys for the encouragement! One of the many reasons I love the Goldie is that it is nearly ground zero for all cafe racers. A stock Gold Star looks so lean, fast and ready to race the streets.
Today was better than Christmas! Look what just arrived, a new UK made exhaust and proper silencer, correct refurbished Smiths chronometric tachometer and the long out of print book "Goldie". Purchased from a Britbike.com member and Goldie fanatic.
vrooom, vrooom...
Thump, thump, thump....twitter

I just read this whole thread, and I think this bike finally found the perfect owner for it. Amazing work. I can't wait to see it finished!

1963 was the last year of the smith's chronometric for BSA and the switch for most mfg's to the magnetic type spedo's and tach's.

Thanks again everyone for the kind words.
On this week's installment of lunch hour update I worked with my friend Pat the welder to repair the broken cylinder head fin, cut and fill a 4” hairline fracture on my inner primary cover, press out my rear brake arm spindle and create a motor stand. I traded shop time with his boss Pete for my labor on Pete's 1971 Honda CB750 which I will get running, timed, tappets adjusted and tuned up after sitting for ten years. No problem, for I have built 5 CB 400, 550 and 750’s and know the motor and carbs well.
Their shop is 160 years old, one of the first buildings in Winona and began as a saloon facing the river, a whorehouse up top and a blacksmith in the back. (welding, whiskey and women-all require warning labels). It later became a Winona Boiler and Steel and the building is filled with ancient machinery, leather belt driven cast iron machine wheels, mammoth brakes, shears, presses etc along with beautiful Miller and Lincoln welders and all the shop toys we lust after. Pat is young, very knowledge, creative and a great guy. I hooked him up with a Honda CB750 that he is going to customize in to an old school bobber.

The inner primary cover under Pat’s magic hand:
I broke off some donor fins from a trashed Triumph 650 barrel weld to my cylinder head using Heliarc (TIG) and 4043 welding rod. Guess what, cylinder fins have iron in them and will not weld to my alloy head… All part of the learning curve. I tried several local options but ended up buying a broken BSA cylinder head on E-bay, so the repair is delayed to the end of the week.
Pat welded an engine stand from shop scrap and I beadblasted my hardware. It is so nice to use a monster industrial compressor that cycles every 20 minutes instead of my small compressor that cycles every couple of minutes. We also pressed out my frozen rear brake spindle without destroying the spindle or plate using their 50 ton press. Always nice to have the right tool for the job.
With a busy work week, I will try to find time to finish preparing hardware for cadmium plating and wait on the donor cylinder to finish my head and get the motor parts off to be vaporblasted. Stay tuned…

wfo guy, yes it is good to have friends with nice equipment, Beer is one of my favorite bartering tools.
A minor victory, my cylinder barrel was at stock 85 mm bore with the severely frozen piston and rings. I had the Engine Store of Winona bore it to just under .030” over standard. There is still a tiny bit of pitting, so I will order a .040” piston and rings and have them bore to match the new piston and that should clean up the last of the pits. No re-sleeve necessary! The Engine Store is a local full service machine shop, do great work at reasonable prices and took extra care and time do it right. Thanks guys.

After
Tiny pitting that should clean up at the next size overbore (.040”)
I have freetime this weekend to move forward on the fin repair and hardware prep.

Re: 1962 BSA DBD34 Gold Star barn find restoration
I wish more of my friends had some of those machines...... making stuff by hand using Harbor Freight tools gets a little difficult sometimes. None of the machine shops around here are interested in doing little jobs. Most have a $100 minimum which is way too much to have something pressed out or a broken bolt removed.... Excellent build, by the way..... lots of info and pics. I can't wait until it is done.....

Thanks all!
Progress. The cylinder head fin and the inner primary cover are repaired, frozen dynamo screws removed, more bead blasting and prep for vapor blasting and cad plating. I love working on my bike.
