Zaskar LE - '93 Edition - Build thread

[SFP]

Ideally would like to keep the parts at no more than a couple of years newer from frame build date.

With an August 1993 build date, a '95/'96 shock I can live with.

Spent the whole night thinking the bike....

Part of me this morning is of the mindset to rob my Hammer Race for parts to build it up so I can get riding time on it.

Still seriously considering the yellow power coating for the frame (attached images for example). My concerns are - I'll need to face the BB and headtube (not that big huge deal, moreso can I locate a local shop with the tools required). Will the serial number and frame size stamping be lost due to the thickness of said power coating? Will I need to ream the seat tube to clean it up? Anyone have exeperince with powercoating a AL frame and wanna chim in?

Forks - Thinking Rock Shox - I should be able to locate some Mag 21's and I can do a rebuild on them.

I had this British Eagle frame powdercoated:

In theory, this was meant to be a quick build that I could later upgrade as necessary, but it's already taking a lot longer than planned.

I bought this unfinished project from Captain Stupido. I did originally consider stripping and polishing the frame to keep costs down, but realised it would take too long. The frame, forks and stem have therefore gone to Yorvik Engineering for powdercoating. Unfortunately, Prismatic Powders have sold out of the colour I had set my heart on and say it will be about 2 months before they make a new batch:

If the powdercoater knows what they are doing none of those should be an issue. Properly masked and applied, no need to face the BB or headtube after, or ream the seat tube - although the place who did my powdercoat are an engineering services so since the seat tube wasn't perfect anyway I got them to ream it out to a more common size at the same time.

No worries about the heat-treating either. Straight from the expert:

...and your source/experience for that assertion is?

OK Deep breath, here goes:

6061 Frame material:
The annealing/solution HT process for 6061 to T0 requires holding for 35 minutes at 980F/530C. Quench in water or water/glycol keeping quench liquid at 100F/38C or lower. Powder coating (PC) temps are nowhere near this.
The correct post-weld artificial precipitation ageing cycle to get to T6 after solution+quench is 8 hours at 350F/177C. No natural precipitation ageing will occur.

Because it is a 6*** heat treatable alloy, 6061-T6 can indeed react to additional...

Don’t powder coat it. Frame deserves better.

Polish it up properly and add correct decals. Then a mag 21 SL Ti and a m900 group and you have a pearl

To be fair 08/93 could be 94MY too so go whichever you like

I have some Rockshox Mags that could do with a rebuild, they came off my '91 Avalanche (the Avalanche has now got the original 2x4 GT forks fitted) I'm not likely to use, pm me for further details if you're interested...

93 is m737 vintage. Light, compact gearing, slr breaking, pretty and half the cost of M900 xtr Judy SLs are nice but so is a mag21 tuned w/ travel extension. I had both and prefer the mag21 BUT... finding seals/ parts for mags is not easy.
