Rikon Tune-up, Part Deux

In addition to the earlier Rikon tune-up, consisting of a new lower tire, a new 1/4″ blade (although I am likely to supplant that with a 3/8″ blade) and tweaking the guides, I also recently re-installed the original rip fence augmented by a curved single-point resawing block.  My own view of this setup is that a fixed rip fence is almost nonsensical on a bandsaw, given the almost inherent drift in the tool design.  But, a band saw that is set up to rip and resaw well is a joy to behold.

Many, many articles and videos have been made about “truing” a bandsaw’s cut.  Personally I find these a fool’s errand for the most part on a small-ish bandsaw if the end objective is to turn the bandsaw into a precision sawing machine.  Sure, I stone both sides of the new blade when it is first running after being installed, to remove any distortion/excess at the weld joint.  I also round the trailing edge of the blade with the stone while the blade is running.  These two steps increase the performance considerably, but almost never result in a cut that is perfectly parallel to a fixed fence.   One option in response to this,  which I have used, demonstrated, and even included in a video, is to cant the fence to the degree of the run out.

A single-point resawing block is a preferable solution, IMHO.  Somewhere along the line I picked up a Kreg brand block and had it available to affix it to the original rip fence as illustrated.

The beauty of the Rikon fence design is that I can have one side outfitted with a curved single point block and leave the other side with a half fence, which is also pretty usable (I have found that anything longer is useless on a band saw).  I do not mind using both sides of the fence and thus cutting in two different orientations, one on the right side of the fence and one on the left side.

BTW, I notice that both Woodcraft and Highland have these little beauties on sale right now.

Bench Top Bandsaws

Recently I was corresponding with a reader who asked my opinion about bench top bandsaws, a preferred option for him because his career led to frequent moves.  I answered him that I have two benchtop bandsaws I use frequently, one a 9-inch Delta bandsaw that must be close to forty years old by now, and a 10-in Rikon I bought about fifteen years ago from either Highland or Woodcraft, I honestly cannot remember.  Each bandsaw has a critical role to play in my work, the Delta is my tool for sawing veneers for parquetry and the Rikon for pretty much everything else of modest size.   (I also have a free standing Delta 14″ and a Taiwanese 14″ with a riser block for resawing.)

In the back-and-forth of our correspondence once I understood his situation I recommended he look into the Rikon.

Some not-too-long-ago maintenance on the machine confirmed my overall impression formed several years ago that it is a superb tool.  Last year during a workshop the saw broke a tire, and after setting it aside for the 9-inch Delta for the remaining days a new tire was on-hand and eventually I replaced the broken one.

Swapping out the tire was the easiest time for that task ever.  After removing the retaining ring on the axel of the wheel and cleaning off the detritus of the tire I started the new tire at one point on the wheel then placed that section of the wheel in my Emmert metalwork vise and was able to install the new tire in approximately one minute.

Since I had the wheel off I gave the lower section a through cleaning then did the same to the upper section including scraping the upper tire with a boxwood carving tool with a knife edge to remove the accreted crust but not cut into the tire, then put on a new blade and readjusted all the guides so that it ran perfectly.  Unlike my other bandsaws I have found that the factory originals work just fine.

I know that in the coming decades this might be my only power machine (along with a drill press), and I am confident that the little Rikon will serve me well.  Even now I cannot think of any recent project that it could not have completed.  Perhaps not quite as fast as some ther machinery, but it would get the job done.  I keep a variety of blades on hand to use whatever suits the task best, and find that a 3/8″ blade suits me 95% of the time.

I’ve have recently added a nice standard feature enhancing the machine’s utility immensely.

Stay tuned.

One Of These Days…

Like many (most?) of you I have a long list of things to do around the shop, usually memorialized by the phrase, “One of these days I’m going to (fill in the blank).”  Given my lengthy hiatus from getting into the workshop over the past few months I have been reveling in a week-plus in the shop.  On my return I was struck by the fact that the place looked like a tool bomb had gone off, the result of me swooping in for a minute or two to get something or other that I needed elsewhere on the homestead, and then failing to reestablish order in the aftermath of that particular moment.  I greatly admire my friends MikeM and MartinO and SharonQ for whom order and tidiness simply flows out of their pores, but that is not the way I am wired, unfortunately.

The impetus for the latest/current tidying of the shop is based on a number of things, the first being the general state of disorder as previously described.  Add to that my desire to get the leg vise for my FORP bench installed and ready to work.  Add to that the currently-in-gestation woodworking/musical instrument making club that will soon begin to convene on a weekly basis in my shop since I’m the one with the necessary space, workbenches, and heat.  So, I need to clear out a bunch of stuff that is just taking up space in order to accommodate three other fellows with their projects.  Then there is the always evolving strategy for tool storage.  And lumber storage.

And, and and…

My first step in this ongoing adventure was to consolidate some boxes of wood scraps and removing a shelving unit of just plain stuff in order to move in my drill press and water wheel grinder.  It’s funny how even by replacing one shelving unit with two machines the place seems more spacious already.  It gives me instant gratification to keep moving forward.

Stay tuned.

Veneer Repair Video Episode 3

You can find the background on this initial offering by Barn Attic Productions/Seed and Fruit Media here.  I am working on getting an archive for all these videos on the site.  Be patient with me, I am of an age and disposition that I still expect flames to shoot out of the compewder if  I hit the wrong key.

In this episode of my recitation and demonstration of the techniques I use to undertake sensitive veneer repairs — sensitive to the artifacts, not your feelings —  such that the compensation (that’s museum-ese for “repair”) is visual harmonious while leaving the maximum of the artifact fabric intact, I demonstrate my low-intensity method for cutting my own veneers on a bench-top bandsaw.  I use this method frequently for a variety of applications, whether I need that one special piece of figured veneer for a repair or if I am cranking out veneer strips for doing French parquetry.


If your conscience is pricked by viewing this for no cost feel free to click on the “Donate” button, any proceeds from which will go toward enhancing the rapidity of producing new videos.  For those of you who have already shown that generous spirit, I am deeply appreciative.




2nd Annual Ripple Molding Soiree – I

We recently convened our second Ripple Molding Think Tank at The Barn and great progress was made.  The aggregate objectives were both vague and simple, to explore the world of making machines to fabricate ripple moldings.   On an individual context I was looking to build my own version of a 17th century machine, as was Travis.  Sharon wanted to start fabrication a petite version suitable for bench-top mounting and produce diminutive moldings for her own artistry.

Since last year’s confab John had already built a fully functional wave/ripple molding machine and wanted to improve its design and performance.

Starting first thing Monday morning Travis and I started cutting up some of my pile of SYP into machine structural parts, stopping to assist John in assembling his unit.  By lunch time we were constructing our machine bases, both generally in tune with my First Edition Roubo prints depicting Roubo’s interpretation of a machine he had never seen.

Meanwhile John was deep into squeezing that last 10% of performance from his machine built in the aftermath of the International Ripple Molding Association first gathering.  He had already nailed the ripple effect (up and down), now he was trying to dial in the wave effect (side to side).

Sharon arrived late on Day 1 just in time for dinner of Mrs. Barn’s outstanding cooking, and we were able to hit the ground running even faster on Day 2.

The first thing we did then was to record John giving us the walk through of his design ideas and manifestations.

He was effusive in extolling the outrigger arm he integrated into the cutter head, stabilizing the front-to-back flexing inherent in the cutting, and a robust drive with a drive gear and a rack mounted to the underside of the moving platen.  That was an unbelievably useful exercise as we were able to get the big picture in a linear fashion as to his working and thinking about the problem, which in turn informed and directed our labors through the week.

Once everyone got back to working on their machines I began devising a system for creating the scalloped patterns that were necessary for cutting the ripple moldings.  First I cut a dozen identical 8-foot strips from 1/2″ baltic birch plywood to use as the stock, then double-impregnated one edge with dilute epoxy to provide for a cleaner edge when the patterns were made.

I came up with a handy jig for making the precision patterns on the drill press.

Meanwhile machines were beginning to take shape all over the place.

The Week Before Ripplemania II

The second annual gathering of Rippleistas convenes a week from today, and I am readying the barn classroom and main room.  I’ve heard back from all three of last year’s participants and they hope to be here, along with one other person who will drop by if he can.  I’ve had no other confirmation of attendees wanting to join us even though the event is open-invitation and tuition-free so perhaps the charm of ripple moldings is less than I thought.

Although I no longer have the Winterthur Museum ripple molding cutter here, it having been made functional and returned, I know that one of our posse wants to experiment with a bench-top version of a ripple molding cutter, another will be perfecting his own machine built since last year, and two of us will no doubt be working on a new machine and revisiting my own machine design from last year.

I’ve ordered a pile of the nece$$ary hardware from McMa$ter-Carr so we should have everything we need to have a week of productive fellowship and undulating creativity.

Stay tuned.

Ripple Soiree #2

Sometimes you get lemon peels, sometimes you get lemon meringue pie.

Thanks to a clearing on the calendar we’ll be convening the second Ripple Molding Soiree and Camp Out at The Barn the week of September 3.  As before the agenda will be to explore the theoretical and practical aspects of making ripple moldings and their machines.

I think all of last year’s participants are coming, including at least one newly completed ripple molding machine in tow.  For this year I know one of the participants is feverishly interested in making a bench top molding cutter to produce diminutive moldings and I am going to work on my prototype from last year and another Felibien-esque c.1675 model vaguely similar to the one we resurrected last year.

As before there will be no tuition fee, this is a mutual learning experience rather than a teaching/classroom event.  We’ll share whatever material costs are incurred and pay for our own meals (normally for a workshop I provide or pay for the mid-day meal).  If you are interested in participating feel free to drop me a line.

PS if this goes well my pal JohnH and I are hoping to teach a “Make A Ripple Molding Machine” workshop some time in 2019 and also make an instructional video on the same topic.

Bench Build *Out*, IRMA 2 *In*

With prep time barreling down the rails, and given the zero interest thus far in September’s workbench building workshop at the Barn I’ve decided to cancel that event and use the week for ripple moldings instead.  It might be or might not be a reprise of last year’s First Annual Meeting of the International Ripple Molding Association or it could be just me and my friend John noodling on ripple cutters in the shop.  I really need to concentrate on perfecting my machine and maybe building another one, and I’ve asked videographer Chris Swecker to mark his calendar just in case John and I decide to make a video as we make both the machine and the moldings.

If you might be interested in joining in, let me know.

Upgrading a Machinist’s Lathe

Not too long ago I wrote about the new antique lathe now residing on the main floor of the barn.  My friend Jersey Jon took it on himself to get the beautiful unit tuned and running.  It is good to have friends like that.

One of the things that Jon stressed was the value in using a new power source for the old lathe, and it is a sermon I have taken to heart.  It causes reflection on the fundamentals: to power many kinds of machines, like lathes and milling machines, for example, you need a lot of torque and the ability to alter the speed of the cutting tool.  Hmmm, where to get a simple system of high torque variable speed power source.  Why clothes racks, a/k/a treadmills, of course.

Last month I was downtown at the electronics store and walked by the thrift store for the animal shelter and there it was — an aged treadmill on the porch of the thrift shop.  I asked, and they had no way of knowing whether or not it worked but they wanted it gone.  I made that happen with a small donation.

Back in the shop I also had no way to know if it worked until I made a new key to replace the broken one for the unit, put new batteries in the control panel, and made sure that the breaker switch was set properly.  I got all that done today and turned it on.  Yes indeed, the thing works!

What prompted the precise timing on this was spending a couple of days working down in the machine room/foundry, trying to impose some semblance of order there, as it has been sitting essentially untouched for more than a year.  I’ve got this wonderful Atlas machinist’s lathe, but the drive mechanism has this monstrously huge 3/4 HP motor (literally much larger than a basketball and about 50-60 lbs) and a whole set of pulleys and such that were such a pain to work with.

cIMG_8176

Depending on my schedule, I hope to swap out the old drive system for the new one by the end of the month (it is not the highest priority at the moment…).  I dismantled and removed the old one this afternoon, so I have passed the tipping point.  I suspect I may start scouring yard sales and thrift stores for more such clothes racks.

Stay tuned.
