  • Have Blue [dot org] » A pair of quick machining projects
    head forward by 5 degrees to complete the setup I seem to have lost the feeler clamp screw for my trusty Blake Co Ax indicator so I used an edge finder to pick up the hole center instead I didn t have a boring bar long enough to plunge all the way through so I bought one just for this project I selected a bar tipped with C2 carbide since the cut would be interrupted due to being a slightly different angle than the original hole I started by setting the boring head to a small enough diameter that it would just start cutting at the bottom of the hole where the offset between the existing hole and my new cutting axis is greatest I then adjusted the boring head to make the hole a little larger set the powerfeed and bored again It was long slow work but I finally got to the point where I had better than 50 circumference all the way through Finally I turned a matching sleeve on the lathe that dad could weld into the axle hole for the whole assembly to ride on an axis pin A friend is assembling a new upper for his AR and one of the components is a Sentry 7 adjustable gas block Unfortunately the freefloat handguard he s using makes adjustment of the metering setscrew almost impossible Dremeling out a simple slot would fix things just fine but would look pretty ugly milling the slot would look much cleaner The problem is how do you clamp a round object while also properly indicating it so the cut is right over the central axis After a bit of pondering I came up with the above solution I first drilled and tapped holes in a 1 square aluminum bar

    what can be sold off into the civilian market it seems quite likely that in another 10 or 20 years there will still be more WWII vintage planes flying than the fighters I grew up with Apparently the government thinks shredding its heroes is for the best and don t even get me started on the USAF curtailing practically all airshow participation due to budget cuts or so they claim meanwhile Canada was happy to send a few warplanes and even their phenomenal jet team to the Rockford air show Beyond my childlike desire for the sound of afterburning turbofans I simply love airplanes in general I m one of those weird people that simply have to look skyward when they hear something passing overhead no matter how pedestrian I m not even very good at being able to tell what type of plane it is It s flying in the air and that s all that matters to me I ve tried to scratch the itch my bookshelves sag with books about airplanes my hard drive is packed with flight simulators and I have a pile of RC planes and parts of RC planes but I suppose that s to be expected And yet it simply has never been enough I need to fly for myself I find it absurd that the concept of aviation can be encoded into one s DNA yet the similar fascination of my uncles and grandfather appear to serve as at least anecdotal evidence that perhaps such desire is more rooted in one s being than might normally be considered To be slightly more blunt perhaps aviation is indeed in my blood I ve been saving up for several years for flight training Flying isn t cheap despite the dreams and aspirations of optimistic 1950s post war America it s not something you can pursue on a whim and expect to succeed unlike getting a motorcycle license 2 Saturday afternoons of training a DMV test bam you can ride a bike I ve heard that getting a private pilot certificate today actually requires more time training than getting a commercial rating 50 years ago Despite the cost I knew that this was something I simply had to pursue Stephen Force is an utter poet of piloting and has about the best summation that I can possibly imagine what do you owe to your 10 year old self No matter who who are or what are your own passions I think this is a remarkably succinct distillation of what your true pursuits as an adult deserve to be If you had a time machine and visited yourself at 10 years old what would disappoint them most about you Seriously consider that for a moment looking at not a stranger but yourself 10 20 30 40 50 60 however many years younger than you now are What would you have to admit to your own self that you hadn t even attempted much less accomplished In

    of the float bowls in order to get home from Madison The second issue was the choke it s been getting progressively stickier until our 4 person ride to Kettle Moraine where it seized entirely in the open position At stoplights I got to look like a tremendous jerk with my bike idling at 4000 RPM and a Vance Hines exhaust to boost the noise even further So after the ride I knew it was time to really dive into the bike guts After pulling the tank and discovering the red brown horror within I removed the airbox and had a look at the carb itself The core issue was plainly obvious a bent plate and choke plunger end on the left side So just bend the end of the choke plunger back into pla snap Well dang Fortunately there s a Suzuki dealer just down the road and 2 weeks later I had a replacement plunger in hand Once I went to install it though something wasn t right Yeah the new plunger top was a bit different I don t have another 2 weeks to get the correct part if the shop can figure out the right part number so I chucked the old plunger in the lathe A 43 drill and a 4 40 tap provided the threads I was after I installed the plunger back into the carb and attached the plate A loctited 4 40 socket head cap screw finished off the assembly The carb airbox and most hoses are now reattached Once I put the gas tank back on and put fresh fuel in I ll see if everything works 2 comments so far Add Your Comment Reply Frankie Flood said 2014 06 17 22 58 You re doing M2M I ve never done

    pieces Reply John Branlund said 2014 06 18 22 51 Looks better than my FDM2000 that s still waiting for head repair Reply Kyle said 2014 09 19 02 52 I picked up a Prodigy Plus for 1K on eBay and had some questions about your experience with the FDM2000 Would you mind shooting me an email Thank you Reply Alberto said 2015 02 02 10 09 Nice Work man I recently bought a not working fdm 3000 I change the asymtek controller thanks to your information So I m in debt with you man I have now some question on where you find the foundation foam here in Italy seems that no one have it or which alternative of foam do you use I hope you like beer because I have to offer you many I wait for your e mail Thank you VERY MUCH Reply Have Blue said 2015 02 02 10 49 I have a few extra foam bases so I probably won t need any more for a while As best as I can tell the foam is General Plastics Last a Foam FR 7104 https www generalplastics com fr 7100 html However I m currently experimenting with some foil sided PIR foam sheet intended for building insulation it s about the right density and I have high hopes for it It ll be the subject of an upcoming blog post I m sure Reply Alberto said 2015 02 09 02 22 Ok I ll try your solution Now I m testing with polystirene x foam used in building insulation and using HIPS as support material but I have problems extruding HIPS When I manually extrude it no problem but when I start a job it extrude very very slow and the torque is very slow

  • Have Blue [dot org] » Support extruder reassembly
    for the day Upon reflection I figured that the extruder probably wasn t the issue in the first place assuming that I had done the rebuild correctly and that the motor drive block or the nozzle was the culprit I removed the motor drive blocks and set the head in the machine so that I could power it up and try feeding the filament through by hand I was able to push the ABS filament through pretty easily but the support filament I could barely budge So I removed the support nozzle and put the model nozzle on the support extruder Wonder of wonders I was able to feed through the filament just as easily the nozzle must be the problem I reinstalled the motor drive blocks and sure enough the support drive was able to feed support filament through the support extruder and model nozzle with no jamming whatsoever I ll try clearing out the support nozzle with a 0 011 drill bit even though I know I ve done so once already and I believe I have a spare T12 support nozzle floating around in case that doesn t work At least I ve finally found the core issue and I ll hopefully have the machine fully functional in only a week or two insert something about famous last words 9 comments so far Add Your Comment Reply Frankie Flood said 2014 05 06 20 48 Argggg What a pain you know I had trouble with the extruder tips on mine when I first received the printer from you They seemed to clog easily until I took them off and did a thorough clean job on them I ended up using a torch to incinerate some of the junk inside I can t believe that the tip was the source of your trouble Reply Have Blue said 2014 05 06 21 31 I can t believe it either but when switching tips leads to trouble free extrusion that s a pretty clear indicator Given how much trouble free operation the nozzles on my 1600 have given me I m surprised this seems to be such an issue especially since you ran into problems as well Reply Have Blue said 2014 05 10 12 12 As an addendum upcoming blog post I ran drills down both ends of the nozzle to clear out the inside as best I could but didn t do a full solvent cleaning I was sure I got it cleaned out as well as I could but when putting it back on bam jam city I ll give the torch trick a try thanks Reply John Branlund said 2014 05 06 22 55 Should you not have one shoot me a line as I probably do BTW how much would you charge to do mine Reply Have Blue said 2014 05 07 07 50 LOL In restrospect while tearing down the head was incredibly daunting at first it wasn t that awful I took lots

    flute endmill and bring it down against a parallel while loosely clamped in the vise Then tighten up the vise while keeping a little pressure on the quill to keep things aligned Viola perfect alignment without a test indicator Next step was to find the centerline of the handguard There wasn t enough clearance to use a cylindrical edge finder on the jaw faces so I flipped the edge finder over to use the conical tip I just had to make sure to set the stop on the spindle so that I used the same Z height on each side Also this wouldn t have worked if the top inside edge of the jaw faces was dinged up since using the conical end of the edge finder in this way gives only point contact rather than the edge contact that the cylindrical end would have provided With the Y axis centered I set my X axis zero as the end of the handguard and used a spotting drill to make a divot for the first hole 1 000 in One of the ball end milled grooves on the handguard would be sitting right under the rail but the groove is off center by a little bit so the spotting drill would be hitting the edge of the groove and not able to make a proper divot So for the two center holes I used a 5 32 endmill to punch holes all the way through 5 32 is just a few thou smaller than the 21 drill used for the needed 10 32 threads After drilling through all 4 holes I put a 10 32 tap in the drill chuck and loosened the collet so I could spin the chuck by hand but still have it perfectly positioned in the
