Hey, WKTaylor asked: ... Please advise... what is '...some Al aircraft control surface parts.'??????? It is pre-bent but not drilled skins that are about to become flap and aileron (for example). Early on in this process it becomes "high value" due to time invested. Regarding the...

Hello, I'd like to use some temporary assembly technique on some Al aircraft control surface parts. I'm planning on initially using 3/32 pulled all aluminum rivets in place of clecos in some places for parts that will eventually have 1/8 CCP-42 (or similar) blind rivets. This is to allow the...

We are very into coupon first - no fear there... b

Had never considered using the accelerator as a primer. Makes sense. We are doing another setup tomorrow and will try it then. Thanks very much! b

We are trying to mount hinges to a control surface and subsequently attach that to mating hinges on a wing in the context of an experimental (homebuilt) aluminum airplane. It is convenient to glue one half hinge to the control surface on a jig for positioning, With this fixturing it is then...

Hey - reply to Will What are your 4130 tubing [and sheet attachments] specification(s) and what is Your starting temper... IE; 4130, AMS63xx [MIL-T-6736, ASTMxxx] [etc] tubing and AMS63xx [MIL-S-xxx, ASTM xxxx etc] sheet plate; and what is the starting HT, IE: Normalized [HT95KSI], HT125-KSI...

Sorry to be unclear. The weldment I was failing to describe is to connect the roll control torque tube (which also reacts human powered pitch control inputs via the silver collar in photo) to the aileron pushrods which are loaded in tension and compression only. They are the common (Aurora...

Hello. I am familiar with the FAA AC-43-13 which has guidance for repair via splice of 4130 tubing. There is mentioned there the use of an external sleeve in no surprising fashion. On the other hand there are these guys...

Hello. Great info on the HFC of which I was unaware! Search worked well as you suggest. Thanks very much, just the ticket. b

Hey - good point on the pilot logic supply. I'm trying to rely on that for uplocks (load holding) so I guess the only hope there is gravity and tapping at install time. I'm trying to use antifreeze as the fluid and as it's 100 psi I expect no diesel effects and a worse time of self-purge...

Hey, Thanks very much for the info. I was able to look up the specifics (solubility at temp for water in my case) and from that I can get enough of an idea to proceed with prototype. In my case I'm probably going with something like dex-cool for the fluid and as it is a 100 psi working...

Hello. I'm working on a hydraulic system for light aircraft landing gear retraction/extension. Everyone I know that operates similar systems says it is very rare (like essentially never) that they purge/bleed the thing. (These are owner/operators, so maybe others are solving that problem for...

Update: Clippard mjtv-5 is suitable and unlike the -4 has 1/8 npt ports for "exhaust" which are plumbed to tank if using oil. Sorry for the bother but in case someone else is in need of this kind of thing... Just got off the line with Clippard and to my surprise they work with oil or water as...

Hello, Summary: I want to convert pneumatic 100 psi 3 cylinder (2 1.5 in 5 in stroke and one 1.5 in 3 in stroke) system to hydraulic (water or atf or whatever works). For this I need a suitable replacement for the current clippard MJTV 4 valve, which has 1/8 npt ports...

Zow. Just what I need. Thanks much! b

Hello. I need push connect fittings for 1/4 od air lines (to 1/8 npt) on a system that has 250 PSI cylinders that are good from -20 F to 200 F. The cylinder maker (Automation Direct) has fittings that are fine on pressure and have a low temp limit of 32 F. Cylinder seals are Buna-N and the...

Thanks for these - Several days of searching and I had seen only Rexroth in passing. I never would have thought to try Mini Powerpack. Regards, b

--- 0 --- <From hydtools in part...> Example of power units including reversible pumps. --- 0 --- Thanks ever so much for that - seriously useful. First appnote of Christmas! b

Hello - Thanks for the Bimba and etc suggestions! They look to be the proper next step. My naive hope was that a bi-rotational hand operated rotary would see the extend side of the three pistons as the load and the retract sides as tank so I could get by with an expansion tank/accumulator of...

Some more clarifications - thanks for the interest. > My limited understanding of aircraft landing systems is that they lock into position to avoid having a constant pressure and yes, you need very reliable systems with redundancy. They typically (like almost all of them) lock down with an...
