come on, lets be fair, its old and metal you like it
Do you think 2.5L would do a lathe and a mill?I'm using paint from Paragon Paints, superior high temperature enamel paint (apparently). I used it on my mill, 2 grinders and a vice. Bit boring all being the same colour but a 1 litre tin goes a long way and I've stuck with the Bridgeport Blue/Grey.
All applied by brush. I don't have a compressor so spraying is out, plus space inside is limited and I don't want everything oversprayed the same colour! It self levels really well if you don't spread it too thinly.

That’s awesome will get it bought from paragon. What primer did you use?I've bought two one litre tins of the enamel in the last couple of years. I've painted my Elliott Model 00 mill, Union tool & cutter grinder, Eagle surface grinder, paramo bench vice and now the Elliott shaper and I've got about half a tin left. Not all those machines got 2 coats. So, if you're going to give both machines 2 coats, you might get away with 1 litre.
2.5 litres will do it easily.
Which enamel are you using? Brush applied or sprayed?
Excellent work as always!I thought I'd add to this old thread to keep all the info on my shaper in one place, rather than start afresh.
When I've been using the shaper to clean up blocks of stock, if I mic the thickness at each end when two opposing faces have been cleaned up, there's approx 2 thou thickness difference over 4". Not much, but it bugs me and has led me to prefer the mill to the shaper as I can get better accuracy with that. I finally decided to do something about it.
First step was to work out where the error creeps in. I put a DTI on the clapper and swept the ram back and forth over the vice base initially, then eventually pulled the vice off and swept the table. What I found was a slope in the centre of the table travel, but at the extremes of table travel the slope disappeared. My conclusion was that the only thing that could be causing this was wear in the cross slide, so I pulled it off the shaper:

Next I needed to check my references for measuring the cross slide, so first off I gave the surface plate a quick check:

Sweeping the DTI around shows the plate is flat to about 0.0002". Next my chinesium 123 blocks:

These turned out to match to within 0.00015". If I'd dusted these together on the surface grinder, I'm not sure they'd end up much better. The blocks support the vertical ways of the cross slide on the plate high enough to clear the lug for the vertical height nut/gear:

I left the other shaft and gear in as its pinned and the shaft provides something to hold on to. Finally I set the cross slide on the 123 blocks and mapped the wear on the front ways:

The two sets of figures are the measurements with the cross slide orientated with the lug at the back and front, the 123 blocks staying in the same place, to try and average out any accumulated errors. After this, I marked out areas that I figured would need more or less scraping, did a crude step scrape before bluing up for the first time:

The result was pretty much what I'd expected. From here, repeated passes were done trying to bring the corners down evenly as these should be unworn (the milling marks from manufacture were still visible) and should have been in the correct plane with respect to the vertical ways. Here it is a bit further on - the blue is a little bit thick:

When I reached the stage below, I stopped as I figured it was good enough for now and I didn't want to remove too much material if I'd changed the plane of the ways. The insides of the centres are still low, but gives me a reference of where things were if more adjustments were required:

After the ways and the surface plate were cleaned up I set it, scraped ways down, on the plate and swept the vertical ways with a DTI. Turns out I'd got lucky and not scraped it wonky. I checked the back of the ways next. These were flat, except for the last inch where they stood less than a thou proud. I decided to reassemble the machine first before deciding to mess with these to see if I'd made things better.
I clamped a parallel onto the table to give me a smooth surface to run a dial indicator across:

The blue line shows the point on the table travel where the flatness deviates by about a thou. In the middle it's flat. The other extreme, with about 0.75 thou error, is 130mm / 5" away:

I'm happy enough with that for now, I'm calling that a win. I'll try a couple of projects on the shaper before doing any more adjustments.
