Alternate Supplier of Machined parts

[Dale_R]

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.

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.

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, looks good. If it's easier, I would consider making multiples as you create these parts. I'm sure someone will come looking to buy them eventually -- when they get to that section.

Jon,

 

I started doing that with the CS50-D's, but my supply of spares got quickly depleted. I even sold the ones I hadn't already pinned into the tubing.

 

I'll start making "shelf stock" of the MKMGA-C sleeves as soon as I catch up with all the orders I've already received! (next month?)

 

I gotta be careful, or I'll be spending all my time making parts instead of building my airplane. Or maybe, I'll have to quit my "day" job (now THERE's a thought ...)

Dale, how's it going? Are you still working a backlog? I hope you're still at it -- I plan to look you up when I get to the landing gear.

Jon,

 

Yes, I'm still at it. The backlog has all been filled now. I also don't have any time, to speak of - so I'm not accepting any orders, for the moment. I certainly hope the "day job" schedule gets back to normal soon.

 

I do have a couple of semi-finished MKMGA-C mount tubes that I expect to have finished by the end of the month, after I get back from an out-of-town assignment. I'll make an announcement, then, of what parts I have that are

available for delivery.

 

Thanks for asking,

Dale R.
