Wanted to update the group on a machine I purchased from PM member Peter...a 24" (??) Putnam planer.

We worked out transaction and payment late last year with the idea that I'd wait until spring to come to MA and pick the machine up. So...the snow melted and weather got warmer, and details fell into place and I just got back home.

I'd seen the pictures before and thought I had a scale in my head...that was about 3/4 of actual! This is one heavy duty bugger. I've posted before about how planers are deceptively heavy and this did not disappoint.

Peter had the machine staged on some heavy timbers, steel plates, and pipe rollers and after about 12 unsuccessful tries to get the trailer lined up dead center with the machine I finally hit it right and we were ready. We made a slight adjustment to the trailer deck "level" by jacking up one side and putting a 2x12 under the LH set of tires which greatly improved my "visual confidence" in not tipping anything over.

The hard work then began, I rigged up a 3T lever hoist to the vertical I-beams in the "neck" of the trailer to provide horizontal pull so the beast could climb the ramps. Pull was very heavy at first but got easier as the machine started to climb. Peter was manning the details of plates and rollers and I was working on pulling the lever...approx 4 "ratchet strokes" get 1 chain link of travel and so you can imagine this takes awhile. I ran thru the 10' of load chain and had to stop and get another bite. There was a strange combination of events as the machine was pulling along...the timbers are soft and tend to dig or "bite" where least expected, sometimes a pipe roller would create a divot and stick and other times would roll smoothly. The crowning moment was when the balance point was reached and it ever so gently eased down on the deck...then it was just a matter of reaching the travel position and getting it tied down....and I tried not to go "short" in my chaining and strapping.

Peter's drive has a quick uphill just before the main road and I tried not to repeat mistakes from another machine move where I lost momentum and traction on a similar adventure and had to be pulled out with a backhoe. So Peter blocked the road and I let the R30 work its magic and all was well.

Getting back to GA (where shop machines are stored temporarily...I realize my profile location is TN which is correct but there are no machines here :(). I was worried about the possibility that my forklift wouldn't lift it off the deck. I do have 2 forklifts (7k and 3k) but the 3k had a dead battery and was surrounded by other machinery due to a rearrangement. However, I decided to have a try.

I lifted the "light" end to jockey the machine closer to the edge of the trailer and was able to pick that up. Next I lifted the heavy end and that was successful too. So I decided to have a go at the entire thing. First order of business was to get the mast as close as possible, I took off the cross-feed "stroke" linkage to get closer, approx 1" from actually contacting the machine. It lifted it up...definitely a heavy load and I could tell near the forklift's capacity as I have to rev the engine slightly to lift or tilt at those capacities...lower loads will easily lift at idle. I found myself in a "rut" in the pavement which required heavy throttle in reverse gear to back away from the trailer, but yet not overtip the machine as I did so...thankfully the steering never got light and I carefully set it down to the pavement, then moved into the warehouse with approx 1" of ground clearance under the timbers.

I'm purely guessing here that the machine is in the 7000 lb range, and that is based on a 16" x 54" Monarch lathe that I own that is in the 7300 lb range and felt and handled about the same. The good addition is that I got some proper *heavy* machine-handling forks last year, 2" x 6" cross-section and 60" long. The previous forks that came with the machine were full taper to a sharp edge and barely looked adequate for 5000 lbs of load.

Couple of unrelated trip notes. I overnighted a couple of nights at rest stops which went well, in hindsight I need to let the truck cool off more thoroughly before going to sleep...I woke up twice early on, sweating due to all the residual heat from the exhaust, transmission, etc conducting up thru the underbody.

I tried to avoid tolls as much as possible, I-90 in Mass was reasonable and I could have shaved some $$ off that if I had taken I-84 farther east. I got hit unexpectedly on I-84E in NewYork at Fishkill as I crossed the bridge. Approx $15 total so not too bad.

Gasoline is another story, this truck is *thirsty* as the best I've ever gotten is around 10mpg unloaded, downhill with a stiff tailwind. Towing the empty trailer is approx 7mpg and fully loaded as above can get into the 5mpg range. However, it never missed a beat (even at 204k on the odo) other than being sketchy at hot-starting...I resolved that problem by letting the truck idle during gasoline stops.

Many thanks to Peter for being a very gracious host, for keeping the machine stored over the winter, giving me literature and history on the machine (another post) and providing bottled water after I ran out! The weather was supreme for this time of year, all up and down the US and so I travelled sans tarp.

I can't tell you how good a normal bed feels after the front seat of a pickup truck for two nights in a row :D

Looks mildly heavy.....................

Wow......a very impressive loading/transporting of a nice old machine. The only thing I would have done is to crib the trailer ramps, but I don't know your trailer and you do (besides, I'm overly cautious).

It's a pity no one has invented a "self curving" ramp of some sort to accomodate the climb of skids over rollers!

Congrats on a very nice one!

Joe, the Thayer & Houghton is buried back in the warehouse right now. It is completely safe! :)

The main concern I have with it is that the table has been planed so thin that the T-slots are ~75% broken out and would never be good for clamping. There are still the "thru-holes" or I could make up a "sub plate" too.

That said, it is a 3500 lb machine (older, *very* ornate) vs. the Putnam at ~7000 lbs and so this will probably do most of the heavy work.

I haven't completely resolved how I'm going to run these machines, my great expectation (unproven) is to attempt to use a VFD and a PLC to run the table rather than using the lineshaft/belt shifter mechanism of original. Not that I've lost any of the original hardware, just seems like possibly a better way to control the motion.

If I was really flush with cash....an 8kW servo motor & appropriate axis-drive would be in the shop :D

As I told Peter, any serious work on the machine is at least a year away. I have no shop facilities here in TN and while I have plans and savings to do so....waiting for some key indications relative to having a steady job for a longer period in time.

I should also mention I had at least a dozen people as me "what is *that*??" while I stopped for gas and I explained it was the original way of creating a flat planar surface..adding for effect that this could be done to a precision of better than the diameter of a human hair. Many people thought it was a printing press. :D There were also quizzical looks from passing cars.

For the correct police followers, I did not brake for any weigh stations, my travel did not correspond with much semi-truck-traffic-volume and so the vast majority of stations were closed. Those that were open apparently had bigger fish to fry....

Been there doing that on an 1860s D. Chamberlain planer of similar vintage. The table is so thin there are "horns" at either end higher than the current table height which the planer tool couldn't reach when they faced it off. But at least my single T-slot hasn't been broken out yet.

I would encourage you to try to keep changes to the T&H (or any antique machine tool) "reversible" if possible. One of the neatest retrofits I've seen for a planer involved a Pratt & Whitney 1880s vintage machine that had been coverted to hydraulic drive (and painted white in the process) Very neat job. Even ole Pratt & Whitney themselves would have approved, I'm sure.

Good luck with Peter's jewel. Truly a "man's" planer. Your description of your departure from Peter's driveway was entirely accurate - and a wise application of kinetic energy - of which you had a surplus, I'm sure.

George...this trailer has very heavy ramps at the end...they've loaded the red forklift you see above with no changes other than to bridge between the crosswise angle irons. The ramp has a lower "foot" which, on a level surface, "self-crib" as the suspension gets squashed down, the "feet" become "hard stops". Then when the load is up on the suspension in the travel position, there is just enough clearance to swing the ramps back vertical.

In this case with the trailer up on an incline, Peter had lots of wooden blocking that we used to reduce the distance from the "feet" to the earth...

....which brings up another subject...since the trailer deck is downhill...if we had been planning on rolling this machine all along, it would have definitely been in our interest to use another "spotting" hoist to keep the load from running away. This is more of a technique for rolling stock, make sure the rear of the trailer deck is slightly downhill to dead level, but just thought I'd mention it...

Thanks for your nice comments! I'm really impressed with the heft of this machine and want to get it working soon.

Joe...you spurred another thought. The T&H planer has an all-spur gear drive with a considerable amount of wear (possibly noisy which could telegraph into the finish...don't know as I haven't run it).

One thing I immediately noted about the Putnam is the helical geared table drive which should be a much better engineering practice.

I also recalled how I gained confidence the forklift could pick the machine up. While driving I was thinking about "what if the sides approximated a 48" x 96" x 2" thick steel plate...on edge"??

Just estimating in my head I rounded this to 50" x 100" x 2" to get 10,000 cubic inches, the real factor for weight of a cubic inch of steel is .283, but I used .25 in this case to arrive at 2500 lbs.

So...if the LH and RH sides were each one of those (similar dimensions), and the table plus crossmembers was another "unit" like that it would make around 7500 lbs....which in the end was close enough. Had it been drastically more I was thinking about what to do next late on a Sunday afternoon in remote NE Georgia....not a lot of alternatives...

Smooooth is good in whiskey AND machine work. And one of the reasons why Sellers and his "worm drive" planer had such an influence. Plus the pulleys were at "right angles" to normal planer convention - and allowed the planer to be "alongside" the lathes - better use of shop space.

Matt,

Thanks for all the pictures! You can't have too many of a move like that or an old machine like that! I can sympathize with negotiating Peter's driveway, too, but at the other end of it. Every time I've been there I've had to use the 4WD on my Ranger to get up the back way to his barns. Like a dummy I keep forgetting to use the front entrance!

I noticed Peter put a hefty set of timbers under the planer. Tim did that on my 6' Chamberlain. Those sure make moving one of these things a lot easier and safer.

As a note on using a VFD. I have a 1HP rated VFD driving a 3 phase 1HP Lima motor/4 speed gearbox running a small 36" planer. The VFD is 3 phase input from a rotary phase converter that has a 3HP motor on it. The drive belts from motor/trans to the planer input shaft are sized to get 10, 13, 22, and 40 ft/min. I can only run the slower two speeds because the VFD can't stop then reverse the motor quickly enough to operate properly at the higher speeds. It's probably because I bought too low a rated VFD. I've tried adjusting the maximun current and amount of braking but it always gets to studdering at turnaround with the higher speeds. I can run the same setup with the VFD replaced by a barrel switch operated manually and everything works OK.

Irby...I found the same thing with a 3hp VFD. Its an older model Reliance Electric device that eventually found a home on a drill press. To get the brake resistor to work one had to purchase a separate module that was 3X the cost of the original VFD....hence drill press service.

The VFD I intended to use for the T&H was an AC-Tech VFD which had the extra IGBT setup for a brake resistor (simply choose your resistor...I've seen many posts on using an oven heating element, etc). AC Tech also had the only VFD that I knew about at the time which had a full 5hp rating from a single phase input source (IOW was not derated).

5hp may be a good starting point for the Putnam (ideal would be 10...but maybe for "Gen 2" once I get things setup...also in my plans are a Phase Perfect so that would open the doors to higher-rated VFDs which don't allow single phase inputs).

I had also intended a "creep speed" or ~2 rpm IIRC which was ideally used when indicating in a part.

Always look forward to your machinery moves Matt. Lots of pictures and a machine that is tied down like an engineers test question. :D

Matt,

It was a pleasure to meet with you and I know the machine is found a good home. It looks easy in the pics, but you did some serious hard work that day and the bright sun was merciless.

I guess we were thinking the distance between the uprights is the catalog width. That would work out too be 24". The catalog scan quotes 7k weight. Consistent with your forklift estimate.

Now, I have no excuse ... I have to get working to setup my other (old style) 24" wide Putnam planer -- before that space fills up with something else.

Those Coffing winches you use are a super tool. I have to get a couple of those instead of using my (chinese) cable style come-alongs.

peter,

Who is the maker of the upright drill(to the left of the planer in the first photo)?
It is a neat and interesting looking drill. It looks like a screw feed for the spindle or the gear rack is set out from the quill of the spindle.
