new sign.... practicing with resins.
« on: March 04, 2020, 04:38:24 AM »
i made this plaque for a family member hitting the big 60 this week... it's safe enough to post it as they won't find it here before he gets it. 

the interesting thing is the resin... i used the stuff found at Lowe's, and to my knowledge the only one brand they carry.

i've done some work with flooding resin... but i've never had cause to use it as finish.  this sign will most likely end up on the guy's shop's entrance, outside.. and the environment they live in is mucho different than the environment we do... they'll see -50*f from time to time, -30*f regularly, and heats as high as (gasp) 90* in the summer from time to time.  So, i wanted to seal the piece completely. 

let's hope it works out. 

the red oak was carved and stained, and painted... it was then sealed with poly rattle can for three coats to ensure the stain (oil) was encapsulated in the poly- then the resin was mixed and brushed on with a fairly high quality brush, yet still torched for those tiny bubbles... nearing the point of solidifying it was rubbed over with a foam brush.  I noticed on the second day of curing tiny little bubbles of stain seeping from the wood and forming bubbles around some of the lower letters- apparently the temperature delta between day and night in the shop allowed the wood to spit some of it out... i'm crossing my fingers that they don't cause future issues.

whatcha'll think?

Good job, Drew. I will be interested to hear how it fares being outside. I seem to recall some posts on the ShopBot forum several years ago about epoxy as a finish for outdoor signs. My recollection is that epoxy does not withstand UV light well, but my recollection could be wrong. Is there a reason why you made the sign in two pieces instead of one? Just wondering.

Nice job. I used to live in Fairbanks, AK which has an environment similar to that which you described. I think it will survive there just fine.

i'm still a novice at this- and when i make something i try to incorporate something i've not done before.  i'm playing with insets, now, and that is something close to inset... the red oak i decided to use wasn't wide enough to accommodate the size i was aiming for, so cutting a piece down for the fox part and insetting it made sense in my mind for some reason.... along with learning toolpaths and tools(bits) used better, i'm closing in on optimum cutting times.  Both pieces of this one were on and off the machine within an hour.

those cub scout signs i kinda knee-jerk made are another example of this... the original design was to take almost an hour- but after playing with it i got them down to less than 12 minutes on the machine.  Of course I could have done better on them, but limited material dictated not to take as much risk... with them, i cut them- sealed them- painted them using rattle can and painters tape to mask area's off, and then ran them through the planer... it worked, but..... i won't do that again unless i'm rushed again.  a couple more coats of varnish on them and allowing both that and the paint to completely dry/cure- and sandpaper or a razor will take the excess (non-recessed) paint right off... because of the rush and likelihood of the paint gumming up i just ran them through the planer- and made a shallow v-cut (.0625) even shallower... lesson learned. 

i had some conversation with the maker of that resin i used and they said "it will thrive outside in harsh conditions!", but it's not like i expect them to say otherwise- i was more hoping to hear in their voice some doubt... the alternative was a bunch of poly coats- and i'm thinking that is just as suspect as the resin?  again... learning. 

thanks for the compliment!

thanks Willie!!! Fairbanks? whoot!!! that is a mighty fine place by my reckoning!  this one is heading to the UP of michigan.  I have a place up there at the base of a ski hill i've never ski'd... it gets wicked cold.  i don't mind it at all for short periods- but i couldn't imagine having to suit up and dress down in a mud room every time you walk out the door, which makes a quick trip to the truck for something forgotten a half hour experience.  It's not like the cold is just uncomfortable- you can get frost bite in minutes in those conditions when you add wind.

i was up there on the 5th of July once... brought everything needed for a 'low country boil' which was something of a novelty for them (fresh seafood and all).. it was in the seventies and people were in shorts and tee shirts talking about how warm a day it was...... meanwhile, i'm in a fleece.. i opened all the windows in my cabin that night with the crisp clean air- and woke at midnight shivering... it dropped to 34* on the 6th of July... and this was NORMAL....

the cool thing about that sign and making them, and because it's family- i save the file and can rip another off pretty quick if something happens to that one.
