Oh, MECA is Maine College of the Arts, whose furniture design department is hosting the Shopbot Camp next Saturday-Shopbot is that company with the Blues.
Trying to figure out what to bring to "Show and Tell". Was wondering if I should only bring finished pieces that came out perfect--OR if people are interested in seeing things like this that show the process and the failures inherent in prototyping?
Any feedback welcome--my first Camp.
Scott, bring your successes and you can mention what you learned (failures)Quote:

Just some thoughts for your first camp. Russ
That's Great Dick! I don't have to bring anything AND I can talk a lot! :)
Thanks Russ, Bringing my inlay test board as with the 16" crack it was pretty much relegated to be chopped into smaller pieces and all the inlay except tree was button scrap:)
Thanks,
scott
I think Dad will be surprised in the morning- Hasn't even seen a preview as it wasn't even a proto file at Noon. Whew!:) 2 new bits dialed in with no scrap test:eek:
Scott, those are outstanding!!! Got to get rid of the day job so I can spend more time on the bot!
Dick
Wow, I guess you got the bits dialed in. The finish is amazing! What bits and settings did you use?
Thanks:)
Nice day yesterday Dick!
Steve, Those were Padauk and had to come out perfect the first time for "Show and Tell" yesterday so I was super cautious and thought I might smoke a bit, BUT they were barely warm.
Celtic was a Kyocera(Drillman 1 -EBay $4.50) .125"D 90degree engraving at .8, .4,16K .06" depth for first pass and then 2 speed passes at 1.6, 1, 17K.
Cutout/Radius was Whiteside #1572 point cutting roundover 1/4"R at .9, .3,15K at .06"pass depth with spiral ramp.(I was worried about about breaking the tip and carpet tape movement as it got close to the full 1/2" cutting)
NO sanding:)
Scott,
I noticed that you mentioned Whiteside bits. I have had very good service out of that brand in my other routers. I guess these could be used in spindle Shopbots too?
Aubrey, Yeah, I usually TRY to stick with the high quality solid carbides the guys on forum recommend, But have several Whitesides I use regularly in the Desktop spindle. Cut quality of Whiteside solid carbide Downs is pretty good(but Centurion is a little better). Like their 1.25"Mortising bit for surfacing, but there was just a "surfacing" thread with a bunch of links and I'm going to try out some of those as well.
1 Caution with the Whiteside Point Cutting Roundover is it doesn't come to a True point like a Magnate, so you have to offset very slightly if profile cutting "On" the line, but I was very happy with the cut I got in Padauk with the 1/4"R and going to try the same settings with my 3/16"R next time, as I think I was running 1.2, .5,15K at .09" pass depth with a straight ramp and it wasn't as good a quality.
For carbide tipped Whiteside is very acceptable:)
Scott, good to see you and meet your dad...good information at the camp...won't be long before you have your vacuum hold down up and running!!
Dick
Same here Dick:) Got the Spalted back home safe and looks dry(Thank your better half for the great protective job!!) Tons of good info from AllStar !! Never even knew "Cover Gasket" existed and certainly didn't know it could work for tiny stuff like the buttons. Is cover Gasket the stuff you used on your 25,000 Coasters? Did you get through all those with the same Gasket Sheet? Too much info in one shot though--Trying to remember which gasket John said was still trying to be killed by one customer--and which material had to be Re-Z'd as the Z changed and it got more and more crushed.
Dad, Liked you a lot( though personally I can't think of a single redeeming feature between the Two of us! :) ).
Oh, Didn't shoot smoke alarm--DID have 1/2" Blue/White spark come from a furnace component when I threw main breaker back on :( Shut furnace down Totally. So no heat/domestic hot since Sat.---Don't DARE fire up the Desktop as this totally unsuperstitious person knows bad things come in 3's :)
Glad you like the spalted...got to thinking about your smoke detectors...there is a good chance that they need to be vacuumed out...dust can set them off...as you know, I work in the fire protection industry and it is part of the annual ritual to clean them as well as "duct" detectors...hope you get warmed up in there soon.
Dick
Who wouldn't like the Spalted Dick! :) Got to come up with something special for that to use it full length, maybe another Paperback bookshelf.
Thanks for smoke detector maintenance info, never done the vac thing. But will put the new ones in accessible high spots with velcro or snap-tabs instead of VHB so at least I can snag them off the ceiling from the wheelchair with a stick or something:)
Who wouldn't like the Spalted Dick!
Scott, that sounds like something you'd have to go to the doctor to get cleared up! The spalting along with the finish/color looks beautiful,....Dick
(scott, punctuation is your friend!:D)
I received an old Sugar Maple (about 30" diameter) in a grapple load of firewood back in the mid 80's...it had nearly a full twist in about 14'...we ran a chainsaw across it to reveal the spalting...pulled it aside and had a friend with a bandsaw mill slab it up for me along with some Cherry we had taken off our land. Unfortunately a lot of it has gotten punky, but we still have several nice pieces some with tap hole in them.Quote:

Yep, sounds better Jack :) :) (lucky if I can remember decimal points some days though!)
I showed your inlays of the tree and zebra to my friend who is a master Luthier and his comment was simply, "that guy is good!"
NOT me Richard, Like my Mom says "That Machine is SOO smart! How does it know how to do that?":)
Just watched TJ's "Font" vid and ready to try a conventional inlay for large fonts and see if I can give Jonas a less expensive option to offer his customers who don't care about about the sharp corners and Teeny flourishes that Paul and Damien's Vinlay give.
Just had a professional photographer here at the house with Dad Monday, tossed some ideas around. Put 1 coat wood butter on some sanded ones for her to take and play with.
She's GOOD:)
Should have given her some 4 coats Watco/hot dipped beeswax/Carnauba ones too!!
She makes my stuff look good:)
They look good enough to eat! :)
I was just thinkin' the same thing. ;)
Nice stuff Scott!
Real nice! What flavor did you say
Those look really nice. The photographer was a great idea too.
Dave
Thanks all:)
Photographer was Dad's idea, I thought I took decent pics, but I was taking them from a Maker's standpoint. SHE was taking them from a grandmother poking around the internet for something special viewpoint and what she would like to see:)
Her way is BETTER!!
She's kind of getting into it I think:)
Here was just a thought she had for a Facebook Page Banner. She thinks we should just get our name out there, and get a little backstory of Dad's idea of starting a few small independent companies in Maine and then cut them loose---Instead of Retiring retiring like most 85 year olds do:)
Going Hard Maple,Black Walnut,Padauk, and Bloodwood for starter production, then maybe Purpleheart,Yellowheart, and Flame Touched Maple in the 9 fluted designs.
scott
I took a nap, and while I was sleeping the photographer (Kelly) made Kirk(Alosada) a Facebook Page:) I THINK she's getting into it:)
Only bad thing is, I shut down my account once I checked how much time I spent on it and now have to open another:(
OH, This will be totally Kirk's company and baby. So PLEASE don't use my Name or Kennebunkport in any Comments. I Just Proto stuff. When Kirk has been in the black for 6 months, Dad will cut him loose and he'll continue on while Dad and I make a new company. THANKS,Scott

A BIG THANK YOU to George Bradley at AllStarAdhesive for taking time out of his day to take a button .DXF and change it into a proto Cover Gasket Vacuum Jig!!! Thanks George:)
OH,
AllStar Adhesives cover sheet gasket page if anybody else is intrigued to hold SMALL stuff down.
http://allstaradhesives.com/cart/category/cover_sheets
Looks very nice.
Scott,
The vaccum jig looks interesting. Are you going to use vac hold down for the buttons going forward?
Dave
Dave,
IF we can get it held down, then yes we'll probably make a job specific jig for each of the different diameter/shapes.
Right at the limit of what people are doing in wood John and George from AllStar said. The fact that the Buttonholes need a gasket for drilling all the way through decreases the surface area. Sure would be nice to get away from tape and to have totally finished product come off(except for finishing).
George just sent me a new .dxf and may start drawing tomorrow(6 more files still to convert to production).
If it works(have to order that bit and a piece of HDPE for proto), then I'll post results in a different thread for those Bored with Buttons:)
scott
Scott, this may be a dumb idea or you have already thought about it. Why don't you do a circle for the vacuum leaving the area where you drill through solid, does that make sense?
Joe
Not dumb at all Joe. But I'll barely be skimming the HDPE to make it perfectly flat, then cut the grid and then the Cover Sheet Gasket covers the top of the channel. So substrate has to be totally flush.
JUST started to wrap my brain around it yesterday when I saw Georges file. I'll probably "Get" it when I draw it out in VCP. "Number than a Hake" when it comes to this stuff so just following the instructions:)
When you get to that point of playing with the job specific jig, if its still hard to hold down the part with vacuum, try using transfer tape / masking tape on the back of each slab of wood, then turn on vacuum, and cut through. The tape should help the vacuum hold. That is if the tape will stick to the wood. Then the transfer tape will come right off after no problem.
I have never tried to hold something that small though.
Dave
Thanks Dave,
Using fairly dense woods, and hoping by sanding to 320G plus a Very dilute lacquer(like I was using to prevent carpet tape residue sticking--worked great for a clean release if you went slow) will prevent too much permeability loss. I'd need a medium? tack 4" wide tape as a few of the boards(usually self resawn maple, walnut) have a slight cup I need to pull flat.
May have to play with cutout toolpaths a little, have it now so I'm leaving .01" onionskin, and then a second final pass .015" lower to cut out completely.
Purpleheart Friday and the square Bloodwoods finished at 5:30 :)
Nice to cut again:)
Yep, Buttons again:)
scott
First proto of this one.
Usually do individuals to test toolpath/cutter strategy, but 60 buttons on a 4X24" wanted slightly better estimate of cutting time so did 10 at a whack and chose Hard Maple as it's the worst case for Fuzzies.
Life interfered and it was on the machine off and on for 4 DAYS:(
Forgot to wipe Maple with denatured or tack rag prior to carpet tape(DID wipe Padauk and NOT lifting at all), so got some lifting and it affected my clean up pass 2 days later(tried speeds up to 3.5,2,17K to speed it up---Z speed was most effective as well as lowering safeZ to .15 and .015"Z2)
As usual I changed the thickness(.185") at the last minute AFTER nesting and as I was cutting out with a Profile/Outside line with a Pointed Round Over it mucked me up and had to add an offset for the cutout.
Need to go back to 1 button/resize boundary vector and renest/ and plug in best quality setting out of the six.
Kinda like the top one where I called out a Kyocera 30 degree engraving, BUT used the 60 degree to make the tiny interweave cut deeper without having to play with Z Nudging(it won't be cut by me and trying to keep it simple for Northern Desktop), and was trying to avoid changing the design as it cuts beautifully in any size above this, but was so shallow in spots that 320G would have erased a lot.
All Kyoceras from Drillman1 on Ebay(Oops top row on right was Onsrud .25"D 60 degree engraving)--first try with his 1/16"2Flute and I like it! Cutout was Whiteside .5"D .25"R Pointed RoundOver.
Rambling,
scott
OH! Please don't notice the Digger:) Original file was referenced to spoilboard so I could just swap out the backer boards and do 6 at a time before changing bits, BUT 3 coats of sanding sealer and 2 of brushing lacquer gave me .015" difference in thickness and I spaced a final dimensioning pass, so I swapped to referencing from the top of material and forgot to save ONE recalculated toolpath at the end of a 12 hour day on the fly!!:(
It didn't break the 1/8" 60, but for the life of me I don't know why:)
5 days mucking around (on and off) in Maple:(
3 hours today in Padauk:)
Ship the file off and start another one:(
scott
Scott the double sided blue Duck brand tape 1 1/4" leaves zero residue. You get it from Amazon - $8.35. Your tea tree suggestion for ants worked a treat. The little blighters hate the stuff! Thanks!Quote:

Having Very good luck with Ace Hardware 2" Fiberglass reinforced Heavy Duty now, and just sanding backs of Padauk/Bloodwood/Purpleheart to 320G and giving a quick swipe with denatured. Held a piece of Padauk that had been surfaced to .185" for 5 days with no lifting before and during cut and good release after:) Maple,Walnut,Cherry still giving that super thin Lacquer wash to stop residue.
Funny(OR NOT!!), Nearest Ace Hardware to Kirk is 40 miles so I was looking for a tape he could Amazon to his doorstep and got a roll of THIS size Duck Brand.....HATE IT, after 20 minutes with decent fingernails I got this at both ends and finally ripped it off (Clean...No residue off lacquered backer) and Chucked it!!! Stuff seemed to like to stick to the paper as much or more than the Board!
Think I remember someone (Brady?), mentioning this but I spaced it when ordering:(
Maybe I got a bad roll, but will never buy 2.44" again!! Shop was 65F and roll had been in 70F house.
I liked the tack and the release on the board though. Just HATED the paper backing.
Wonder if it was just me? Or is there a trick to it I don't need for Ace brand?
Did I buy the wrong type?
Thanks,
scott
Bloodwood Proto design cut Tuesday with Dad.
Need to re-orient Button 90 degrees so Points on Fleur run more with the grain to keep the "tips" supported.
Getting good pocket finish at 6% stepover with Kyocera .125" 45degree from Drillman1 in 1 slower Pass(.05"), than faster first pass and then a second speed pass(Probably wood movement and second pass was 2,1 so ANY cutting resulted in lower quality?).
Need to re-do Celtic files if it's the same case in Maple,B Walnut and get same quality.
Save a LOT of time, as does increased stepover---Going to see if I can get away with 7-8% stepover today.
Still Tweaking and may Finally dare changing VR's today thanks to Brady's article.
Oh, Finally getting production files referenced to BOTTOM of Backer Boards...Now IF I can only remember EVERY time to change the little red dot on material set-up to the BOTTOM of material:(
Drove TWO 1/8" bits into the backers in TWO days!!!
Yes Desktop can lose position!!
Second time I forgot to C3 as well as C2 and X,Y were about 1.5" off and I didn't catch it because it was a first run.
VERY interesting design in B Walnut....Good thing we needed samples for Dad to play with Vibratory Tumbler:)
scott
Also found out I can BOG OUT Desktop spindle! Normally cut Ocooch .25" stock to dimension (.2"), but ran the same file for some shop cut blanks that were 3/8" thick. So instead of cutting .03" at 2.4,.5,12K with a 1.25" Whiteside Mortising bit, First pass was .155" in Maple at same setting.....5" ramp and she TOTALLY stalled out about 12" into cut. Changed to 1.5,.5,13K file and no problems.
NOW a separate file for the table sawed resaw material.
