Dale_R Posted July 5, 2005 Share Posted July 5, 2005 Canardians, I am a machinist by avocation. I'm making as many of the parts for my COZY as I possibly can, which is pretty much everything that doesn't require welding (and it may not be much longer before that is no limitation.) Whatever I've already made, or already have the tooling set up to make, I've offered to make for anyone else who is having a problem with Brock - either their delivery schedules or their QA (or, rather, lack thereof) - or just likes the features of my parts better than the "stock" item. A home machinist for over 20 years, I got my start, nearly 40 years ago, as a machine operator in an aerospace shop, to supplement my meager Air Force pay. I spent a little over a year as an apprentice in a shop that made aerospace fasteners (SPS-Western, 1970-71) hoping to become a tool and die maker. A slump in the aerospace industry redirected my primary career into the computer industry. Bear in mind, my shop equipment is state-of-the-art ... for 1942. No CNC here, so I'm doing this for love, not money ['though you might not think so from the prices - however, on one project, I discovered - after the fact - that I'd been working for about $2.50/hr. <:0 ] I hope you'll forgive me for being so verbose in this, but I included the introductory material so that you'll have some idea of where I'm coming from. Here's what I have to offer, so far - [#1] Ch. 16: 4 variants of control rod inserts - all are 1.375" long overall (my originals were longer than really needed to insure that the HM-4/MM-4 shafts wouldn't bottom on the rivets); have 1/4-28 threads that are at least 2 * diam. deep (1/2"); have 1/2" diam. heads that are 1/4" deep: PN: Material: Step diameter: ---------------------------------------------------- CS1-C 2024 AL 0.441" (for 0.028" wall tubing) $6.25/ea. CS1-D 2024 AL 0.427" (for 0.035" wall tubing) $6.25/ea. CS50-C 304 SS 0.441" (for 0.028" wall tubing) $7.50/ea. CS50-D 304 SS 0.427" (for 0.035" wall tubing) $7.50/ea. The AL parts have swaged threads (internal equivalent of external rolled threads) rather than cut. Also, the AL parts are primarily intended for EZ builders who are using 2024 control tubing up front. They are not recommended for use in the engine compartment - per Burt Rutan (however, if you have a fire back there that is hot enough to melt your control rods/ends, you probably won't have control _surfaces_ long enough to get back down safely anyway.) If you have special needs (e.g. tubing that is just a skosh too thick or thin) I can make them a little smaller or larger for the same price. Lead time is about a week. [#2] Ch. 9 - Main Landing Gear Someone asked me if I could supply MKMG-4 bushings. Yes. Then matters got very involved. I sent bushings made to the maximum spec (0.502"). I was told they were too loose. Long story short, I ended up making a set of bushings .002 _undersize_ in order to fit this party's undersized MK100 studs (and match the smaller diameter of the TAPERED (probably made with a worn-out reamer) MKMGA bushings, which were 0.501" at the outer end but only 0.497" - 0.498" at the inner end.) The result is, I now have a set of reamers that allow me to custom fit bushings to your needs. MKMG-4 Bushing 0.501: inner diam. (Standard bushing +/- 0.001" $17.00 ea. 0.502: inner diam. (fits everything, but at maximum clearance) $18.00 ea. 0.500: inner diam. (minimum diam. of spec. - may not fit some $18.00 ea. heavily plated MK100 studs. 0.498: inner diam. (for MK100's that have been shaved down to $19.00 ea. fit undersize or tapered-hole MKMGAs) Special lengths (longer or shorter than the 1" plans spec.) $19.00 ea. [#3] Then came the announcement about the two failures of main gear mounting sleeves. Now I see why - with the entire load of landing being born by the inner end of the tapered bushings, that's where all the stress will be inside the sleeve. Following Bob Oertel's lead, I'm toolingup to produce a one-piece replacement for the MKMGA ass'y, but from 304 SS, instead of 4130. This price will last as long as I can continue to get a "friendly" price on the 304 bar stock: MKMGA-C Sleeve (still in development - no delivery date yet) $50.00 ea. [#4] Ch. 13 - Rudder Pedals These are basically the same actuators that I made for Brian DeFord: http://www.deford.com/cozy/chap_13-3.html They will look a little different, because I'm using a different production method. BAFHP - Brake Actuator $70.00/pair connecting rod from hanging pedal to brake master cylinder, with slotted fork. Prices include USPS shipping to anywhere in the USA. As I add items, they will be posted to this page on my builder's web site: http://members.cox.net/rogersda/Products.htm I am open to making parts that I haven't yet made for my airplane, but I won't know how to price them other than to ask whatever Brock is, unless I find that I can produce them more easily than the price would indicate. Some parts, such as the stamped items, I don't anticipate offering for sale, because I can't make them economically enough to be worth the effort. Others, such as the billet nose gear fork ass'y I'm working on (I don't like castings), I will not offer until my airplane is flying and their durability has been thoroughly proven. I am also open to special requests. That is how the BAFHP came into being. Dale Rogers, COZY MkIV-R13B #1254 rogersda [at] myway [dot] com !!!
