I have selectively replaced various Commando rusty nuts and bolts, and they were quite reasonable.
I don't recall if I priced out a full set though.
(I was a little surprised they weren't available as a full set or kit, as some other makes do offer).

I have purchased a full set for an early dommie project, from a specialist supplier. They were a fair fistfull of $$, but the finished product was worth it to have all new fasteners.

I'd be a little curious too if some of your rusty bits sent off for replating were feasible to be replated - getting rid of ALL the rust would be a slightly major undertaking.
I've done an electroplating course where I redid the cad on a few items, and if you can't just wire brush them to bare metal - and have to resort to linishing or bead blasting to get them clean - it becomes very time consuming and expensive.
Got a pic of your previous replated items ?

And by the way, I don't think I've said "Thanks!" yet for all these detailed pictures of the disassembly, the parts, the new parts coming in, and the anticipated parts of the reassembly .... !

Thanks!

OK, I admit it, I'm addicted to brake fluid.

But I can stop any time I want.

What % of a Commando's nuts and bolts would that represent though ?
Nearly all the bolts for a dommie would fit in a box that size.
Probably weigh 3 or 4 kilos.

That is a concern.
If you just go to the local hardware supplier and buy off the shelf nuts and bolts, the price can tumble, considerably.
Remember, bolts are a heavily discounted business, big customers can get up to 96% off the list price.
(think about that !)
(Although shelf prices are already probably at least 80% discount)

All the green globe bags I've bought recently, a smallish sample admittedly had the correct bolt head markings on them.
Always keep the old ones to compare - and label them.

Interesting thread, so to speak.

Tumbling small parts to derust is very cost effective as would using a chemical bath with acids compatible with the later plating process. When your plater is charging a flat fee for x lbs weight then getting as close to x is a no brainer. Only wish we could get the same service in UK but cad is banned.

There is no serious/structural rust on any of this stuff. When there, is, the prep process they use results in very selective cleaning, producing rough and pock-marked bits. THAT is when I'll order new replacements (until I ever exceed 165#, it is basically "free" to try to salvage what I can.

Over the years, I've been doing shop-wide roundups of nuts, bolts, washers, screws, and assorted small bits and including them in client, personal, and "for sale bike" batches, so I'm no longer able to throw in more than a handful of my extra stuff.

I once sent 55# in a batch; that's the biggest to-date. USPS flat rate medium box was the best $13 spent! Try THAT with UPS...

The finish on those cad bits is quite impressive.
Well worth doing them indeed, and not replacing them.
Thanks for the pics GP.

A lot of aircraft parts specify cad plating, and if it specifies cad plating then it must be cad plating. Try your local aircraft refurb guys to see where they get the cad done. It will probably be to mil spec, so might be bit expensive...

That does not work, I know where the cad plating is done but unless its parts for a plane its not allowed, full stop.

Pre-heated the oven to 250F, set the cases in there and the outer races fell out in less than 4 minutes. No tapping, nothing; just "clunk".



Next batch of new parts arrived today: Shocks, headlight shell, brake pads, gasket set, handlebars, master cylinder overhaul kits, clutch & speedo cable, headlight wiring harness, kick rubber & isolastic gaiters



More parts from 3rd batch of parts- Main bearings, iso gaiters, rear hub cush rubbers, shifter rubber, oil tank rubbers, shift shaft seals for primary.

Case halves spiffy clean after a soda blast and a bath in fresh Simple Green 5:1 with water.



Crank cleaned & re-assembled



Rods installed on crank with new bearing shells, nice and slippery.

Good stuff for engine assembly.



Specifically designed for engine & transmission cases with flange faces.



Assembled crank (with rods, shell bearings, and main bearings), and cam (with thrust washer) is all that lives inside the bottom cases.



Crank spins so nice and free, as does the cam.

Chrome parts arrived, half the batch...



The other half of the batch of chrome parts.



Polished hubs and new rims are on their way to Buchanan's to be laced up and trued, tires are on the way here.

I'll be picking up the powdercoated stuff next week; by the time we return from Thanksgiving in Austin, the Cad plated & polished stuff will be here and assembly can begin in earnest.

That's really going quickly and really looking good. This is a terrific tutorial on what can be done with an old bike if you get on the job and stay on it. Very inspiring!

I prefer the anaerobic gasket makers like LocTite 515 for that kind of sealing rather than the solvent-based sealers, but you have to go with what you know works!

Powdecoated parts unpacked. The powdercoaters masked only the basic holes, NOTHING else. They got a new guy doing the masking and he totally overlooked my specific instructions. Now I need to spend a couple of days cleaning up all the important bits; what a nightmare.



Tires, tubes and rim strips awaiting built up wheels to return from lacing.



All the cad plated hardware sorted after carefully laying each "before" photo out and checking each and every item. As it turns out, nothing is missing!



Polished parts confirmed on their way back. Should be able to have the completed chassis & suspension with transmission in place by this weekend...

Jewelry arrived from the polishers!



A bit of a hiccup with incorrect rims that were dropped shipped to Buchanan's to lace up to the hubs; I'll get that straight next week...

Spent an hour with the dremel burr, that's an hour I hadn't planned on. Anyway, cleaned up the tranny cradle, yokes, frame holes and steering neck.



Swingarm mounted to tranny cradle and lubed, sub-assembly mounted to frame with shocks and rear isolastic unit. Rear end done.



I.D. tag installed, forks assembled with all new seals & bushings, yokes installed with new bearings & spacer, forks installed with headlight ears. Front end done.



Wheels are going to take a while. Talked to the supplier who claimed the Central Wheels rims thet they sent to Buchanan's were spec'ed wrong. I'm going to be be a bit beyond "miffed" if they don't pay pick-up shipping and cover shipping on the CORRECT wheels they'll send in a couple of days. Anyway, this won't be a rolling chassis for a while, a week at least.

Heated the transmission case & inner cover at 350F for 15 minutes, then dropped them on the front deck from about 10" up and out popped the old bearings. Had the new bearings in the freezer a while before putting the cases in the oven, so they dropped right into place with absolutely ZERO fuss.



Transmission shifting quadrant & camplate properly timed, cluster installed "by the book". Again, zero fuss.



Outer cover was a piece of cake with new inner & outer gaskets, all seals & o-rings replaced.

Horn was rather scruffy indeed.



Totally refurbished horn, like new.



Tranny installed in it's cradle, and snugged down nice and tight.

Battery tray & horn installed before the rear fender goes on, and before engine goes in. So much easier.



Most of the electrical gizmos in place



Coil brackets loosely in place, still need to install the ballast resistor & capacitors first, then install the coils later (to keep them out of the way of installing the head).

Turns out the rims WERE the correct ones, Buchanan's are at work on them and I should have them by next week.
