Flattening the sole on an HNT Gordon Plane

Skip in Falls Church

>A while back there was some brief discussion in one of the threads about flattening the sole on HNT Gordon planes. The question came up as to if they were flattened the normal way, what about the brass mouth insert. The suggestion was made that it would probably be best that the manufacturer be contacted for instructions. That was an excellent suggestion, BTW, who ever made it, thanks.

As it turns out, I have an HNT Gordon smoother that was giving me a little trouble - but then I didn't use it that much. I finally got around to checking the sole and it turned out to be less than flat. Keeping the above suggestion in mind, I emailed them.

Terry was really great - he returned my emails promptly and gave me great support - even though I made it clear that I had bought the plane second hand. For anyone that needs to flatten the sole of one of these planes, you do it the same as any wooden plane - put it on something flat and sand the sole flat. The process did open the mouth of mine a little - from 0.003" to 0.006", but it works great now. Terry did say that if the process opend the mouth too much there were some further things that could be done - but I'm happy with it the way it is.

I did what you did but my resulting effort wasn't as good as yours. The brass mouth seems to have resisted the attempts to flatten the sole so I now have a plane with a high spot in front of the mouth. More like a compass plane than smoothing plane :-)

I haven't given up on this but it is on the back burner while other projects take precendence.

>If you haven't dropped Terry an email, you might give that a try. He was very helpful and might have some suggestions.

>I certainly intend to do that. Just too many other major problems at the moment which I will just do this as a Just-In-Time task. My memory being what it is I will probably forget :-)

>Hi Skip,

I noticed that the performance of my Gordon smoother dropped off a bit-upon checking the sole with a straight-edge a slight hollow was discovered. I put a sheet of 220 sandpaper on the bed of my planer and sanded the sole flat again (only a couple of minutes work!)

She now is back to 100 percent efficiency again!

Just remember to leave the blade in with the wedge tightened up as if you were using it (with the blade pulled up into the throat, obviously!) and use the plane with the same grip and pressure as if you were planing.

The smoother is my favorite plane-I recently got the 1 1/4 shoulder plane and an Ebony block plane. Yes, a happy woodworker am I!

best regards

Philly

original thread *LINK*

>The original thread is below, and I'll put out the pitch for scraping again. Everything I said before, plus 1) it is the only way I know of to remove convexity without losing a lot of extra sole material pushing it across sandpaper different directions, 2) it manages the lowering of a high mouth block much better (and leaves the brass smoother and more even than sanding will give you unless you go through a whole bunch of grits), and 3) all it takes is thoroughly cleaning and lightly waxing a reference surface (my granite block needs that every six months or so anyway); no multi-stage cycles of spray/stick/sand/scrape off the gunk/etc.

Sanding at coarse grits can be a lot faster for bringing things into the ball park, but (once the block is uncovered and clean), fine tuning by scraping is potentially a lot faster. On the other hand, if Terry says sanding is fine, it is a good bet that it is, and will probably be easier to pick up than hand scraping, at least until you get the hang of using a blade.

2 cents, discounted by the two hours of sleep I got last night; I hope the above makes at least some sense.

>There is a Swiss patent (No. 1171, 1889) about a mouth closing wedge like the one Steve Knight uses. It states that by tapping the wedge to protrude just a little bit, the plane can be used to smooth low spots and, in jointers, to produce a spring joint. Just like your plane it would work like a compass plane with a very large radius.
