Refurbishing a MkV 510

Aah Florida. One of the rust buckets of the world with its salt water.

If you want stuff to last live in Arizona. If you want life to be 'interesting' live in Florida. But you will hafta deal with something anywhere you live.

Ed, so true,

Have you dried out yet from the heavy rains in the Northeast? Hopefully much of it didn't get to you.

John4337,

Your continued efforts are looking great. Have you thought about upgrading to the 3" casters at some point? If so, now would be a good time to add the extra mounting holes to the legs. That way you can simply un-bolt the retractable caster assemblies, replace the casters with the new 3" ones and re-bolt the retractable caster assemblies back on the legs in the new upper holes. If you decide not to add the new holes now it is not a difficult job to do it later when upgrading.

We did well this time, thank you for asking. The rain was heavy but no extreme winds that could have led to loss of power. And we the previous hurricane, Henri, bypassed us altogether so the ground wasn't saturated and the waterways weren't already inundated. I used to be Ed from New York and I understand what a disaster it was down in NYC and parts of New Jersey and Connecticut.

Thanks. The Evaporust has been incredible, all the castor parts were just covered and they came out great. I had ordered a new set of regular casters before I saw the 3 inch, perhaps down the line I’ll upgrade.

Big step, I have a base assembly.

BTW, does anyone know the measurement between the base legs, or do I adjust to the way tubes when I get there?

Thanks.

What measurement?

The bench tubes should be inserted into the base castings so the end of the tube touches a small stop rib.

The bench tube separation is determined by side motion stops in the base casting. The clamp pushes the tubes out against the stops.

[John4337]

The end with the tie bar lock has stops, the other base piece didn’t.

Measure the depth of insertion on the other end and match it.

The real test comes when you put the way tubes in. Sink them all the way into the castings, check for square and level (not twisted) and then lock it down. If the locking mechanism isn't smooth you might need to loosen those legs and tweak but I don't expect that will be necessary.

This is the time to be real fussy about about dimensions. Square, plumb, level and tight. It will be easier now because the headstock and carriage are out of the way. It will payoff later when you do the alignments.

Nice work thus far. Don't rush to the end.

BTW - the measurement that you ask about will be very close to 48 3/8" as will be the way tubes.Whatever they are, measure the diagonals for equality.

Thanks very much, gives me a great starting point. The way tubes are cleaning up nicely, some staining, but no pitting, so I think they’ll be good. I still have to dive into the headstock. Based on the S/N, looks like the machine dates to 1984, so I’m sure there’s a lot of work in there.
