The gimpy plastic [censored] that passed for a head on my otherwise OK Joe Blow finally fell apart. I've got three bikes with presta and one with schrader valves. I'm tempted to just get a good 'ole brass Silca presta only head, as they're pretty bomb proof, and using a frame pump on the schrader bike the rare times I ride it.
Thoughts? Do those brass schrader to presta (not to be confused with the common reverse) things work?

I've changed all of my Silca pumps from the presta heads that quickly stopped staying on the valve stems to the Topeak Smarthead. The cheaper Topeak Joe Blow pumps come with a cheaper pump head.

I'd looked into putting a Smarthead (which I bought) onto my Joe Blow, but never got around to it. The Joe Blow unfortunately comes with a one-piece tube and head, and if I remember rightly, putting the Smarthead on involves some cutting and splicing.

From the pics it looks like it'll thread right onto mine. At any rate,
I'm not intimidated by hose clamp tech. I've got the JB "Max" model, FWIW.

The kit for the Smarthead comes with all kinds of adaptors and comes with a new hose. It should be just take the old hose and head off and put the new hose and head on.
For the Silca pumps there was no adaptor that worked in the kit but I was still able to slip the hose itself over the barbed brass end on the Silca and use a hose clamp to tighten it. I did not splice anything.

Hmmm, they stock this at the local REI and I've been skeptical of it. I want a second opinion before I commit. :-P
I've got the Smarthead on both my Joe Blow Pro and my Blackturn TP-3. It works great, except in very cold weather, where it can be kinda finicky with Presta valves and I have to get the head on "just right" to avoid leakage while pumping.
Works great for topping off car tires too.
The pump head on Topeak's cheaper pumps (like the JB Sport) aren't very good IMHO. My brother has one of those and there's just no comparison with the Smarthead in terms of ease of use.

I have one of the double Silca brass heads, where the presta head screws in/out of the schrader fitting. Like this but all brass:
Oddly enough, although it's not as handy as a clamp-on head, it's the schrader that works the best of the two (for the kid bikes), given the presta valves currently available.
For inflatables, I use the clamp-on Zefal, which holds a needle filler just fine. No gauge, of course.
I'd love to get a clamp-on, instant convert or easy convert pump head, but the ones I've tried (several) are just too cheesy. --D-y

I'd be grateful if you would elaborate, as that head was on my short list. What are the presta shortcomings?

We have a brass Silca head that is both schraeder and pista-$12...

There's no clamp. The head doesn't hold tight on all valve stems. With some, it works as we (like to) remember from days of old <g>. If you google, you can find a pressure release button that Jobst Brandt added to his Silca head to make it easier to get the head off an inflated tire's valve stem. WIth some valve stems, you pump with one hand at least to get started, because the head leaks without backup.
I still use the thing (30yrs almost) but I'm ready any time someone comes up with a clamping head that is not made outa cheeze. --D-y

I've had great luck with the presta bell shaped head and miserable luck with the head that does both by screwing on to Schrader valves.
My best head is the Topeak Smarthead. I it inflates Schrader valves fine, although I don't do that often. The plunger, used for Schrader heads does a nice job of opening the presta valve before air goes in.

Correct.

Now I remember what the "gotcha" is - it isn't just that the Joe Blow has a one piece hose and head - that could be solved easily by just replacing the whole assembly, as you suggest. The problem is that the hose is also permanently fixed to the base of the pump (at least on my model) so there is no way of attaching the Smarthead without cutting the old tube and splicing/joining it somehow to the Smarthead hose.

"has a one piece hose and head"? No it doesn't. Not fatally anyway. Use a razor just behind the head, 95c hose clamp for the new head.

Yes, I was thinking of doing something like that. Just haven't got around to it yet...

If your brass Silca pump head doesn't stay on the valve, it means the gasket is worn out. These should be readily available from your LBS, or on line. E.g.

Grazie! I think that's what I'm gonna get. After this gimpy plastic [censored], a classic brass number should be satisfying. I always enjoyed using the LBS's silca head when dropping by, didn't know it was available in a convertible version. Excellent! Dov'è il bagno?

I've about had it with the Silca brass pump head on my Silca track pump. Besides the gasket wearing out frequently, because it doesn't depress the valve stem, I've got to put about 180 psi into the pump before it cracks the tube valve. I have to be careful I don't blow the gage. This is after I tap the valve stem to loosen up the seal. My Joe Blow pump with the thumb lock is so much nicer to use, and I don't loose pressure already in the tube by having to tap the valve stem to loosen the seal. Pulling off the pump head is a pain too. I know there's old timers that wax nostalgic about Silca pumps, parts are available to rebuild them, etc., but there's better pumps out there.

If I live long enough, my '72 Silca should be on it's eighth or tenth washer twenty years from now. Check with me on your plastic one then. Of course as all things cycling, riders vary in their taste.
