M00N37 Posted July 16, 2019 Report Share Posted July 16, 2019 Where can I send RJ4010 Waste gate, RJ4002-21 Exhaust stack, RJ4002-41 Exhaust stack and RJ4013 air inlet assy for overhauling/fixing ? I saw in my logbook that Aerospace welding used to overhauled the waste gate and exhaust stack back in 2007 but I just called them and they no longer do this. 1 Quote Link to comment Share on other sites More sharing options...
carusoam Posted July 16, 2019 Report Share Posted July 16, 2019 While you wait for responses... We can also ask the RayJay guy... @tomgo2 doc John had one OH’d so he might have an idea... @M20F-1968 Best regards, -a- 1 Quote Link to comment Share on other sites More sharing options...
M20F-1968 Posted July 16, 2019 Report Share Posted July 16, 2019 This is a tough problem since you need a welding jig to make these parts. Making the jig costs as much as making the parts, but then you can make all the parts you need (under owner fabricated parts, without PMA and for your airplane only). Ray Hussman made parts for me back in the 2004-2007 time frame. He had the original RaJay welding jigs but became seriously ill. You could use a salvage engine block for some of the jigging. I also recall that some of the stainless exhaust pipe stock are made of odd radiuses which may be difficult to obtain. Check with the various welders and see what they may be able to do.

I'll look at my logs and see who did it for me about 15 years ago. 1 Quote Link to comment Share on other sites More sharing options...
M20F-1968 Posted July 16, 2019 Report Share Posted July 16, 2019 Also, you do not want to "overhaul" the wastegate which was originally made of exhaust tube stock. The two systems I rebuilt had waste-gates made from much heavier material. You will want to do this since the original material twists and bends with heat.

John Breda Do you mean I should make a waste gate using owner produced part ? What is a reasonable price for doing this ? Quote Link to comment Share on other sites More sharing options...

MIm20c Posted July 16, 2019 Report Share Posted July 16, 2019 Mine was done by customaircraft.com back in 2013. The workmanship and fit is top shelf but the cost was right up there. Don’t be surprised if they ask you to sit down before reading the invoice 1 Quote Link to comment Share on other sites More sharing options...

Don’t be surprised if they ask you to sit down before reading the invoice Clinton at CustomAircraft does awesome work - you won't find any better. The best part for me is that they are local to me. But I don't typically rave about them here because they gave up there repair station status some years ago when the FAA demanded their repair stations to physically separate premises used for experimental vs certified work. Most could not afford the added overhead. So you can't get FAA return to service paperwork back. I've never found them to be expensive though; especially for what they do.

It was around $6k for everything including wastegate, tip to tail if you will. Keep in mind this was funded by the PO so it might have been embellished a little. 2 hours ago, kortopates said: I've never found them to be expensive though; especially for what they do. No, in aviation terms not too bad. No complaints with my very hard to fit system. Quote Link to comment Share on other sites More sharing options...
