I was so saddened to hear of Kent White's passing. Amazing talent and source of priceless equipment. I was looking to get another set of TM 2000 glasses and lens but I cannot find them available anywhere. Does anyone on this group have a source. They are an amazing advantage when gas welding...

I recently came across an article about new water cooled cylinders to fit Lycoming 4 and 6 cylinders made by AC Aero. Does anyone know much about them? They claim 350 hp from 6 cylinder and 220 hp from 4 cylinder with less weight. They claim 42 and 28 lb weight reduction, respectively and able...

This is a mod for the tool Eric Newton demonstrates in his builder manual. I wanted to have something that could locate tabs inside and outside the frame tubes.

has anyone else considered or actually built their cargo doors of something other than square tube? $8.75 a foot seems a little crazy for a door frame. I am thinking of aluminum door panels built up of a C channel perimeter and riveted skins inside and out. I would have 4130 hinges and latch...

Does anyone know the source of the rudder steering horn on Bob's Patrol? I am thinking it is one he fabricated from 3/4 bar and approximately 0.100 4130 sheet. I would like to do the same. I looked at it closely at Oshkosh but never asked. I think the 4 place in the booth display had the same part.

I have my tundra tailwheel tacked in place on the fuselage. Seems to have appropriate kingpin angle with room for loading to gross weight

does anyone know if the seat drawings from Kevin Deshazer are still available? I want to build my own and it will be much easier if I have dimensions and tubing sizes.

I recently acquired a C-172-B to fly as BH-535 comes into being. I am having transponder issues which I think I have tracked to the antenna- it keeps breaking off. The last one I put on broke off before flight and I finally figured out that it was "the dog ate it". Or just chewed it off the...

i have never worked with bronze and I am not sure of the designation of "hard bronze" . I find bearing bronze, aluminum bronze which seems to be stronger, as well as other alloys. I want to get the right stuff and only enough for 4 caps, 2 for my BH and 2 for my Patrol. Most sources want to sell...

Can anyone tell me the difference in the 3 bolt versus 6 bolt ABI and Cleveland wheels other than the obvious hardware and about $300? Ready to buy wheels and wondering if there is significant strength or load limit difference. I am planning on 31 inch Bushwheels as well. i assume that both are...

i am hoping someone has an easy solution to a problem I am encountering. My welded bearing points have a lot of friction. The aileron/ rudder hinges, control stick pivots, elevator bellcrank, etc have excessive friction that will result on very heavy control resistance unless I find a fix. A...

i tried my elevator counterweights as described by Eric Newton in his guides but did not like the results. So I melted them out and redid them by sandwiching the tip between 2 pieces of plywood and pouring them vertically. I am pleased with the end results.

What is the source for the -B stinger for tail wheel? I have welded up my basic fuselage with the exception of the attach points for the tail wheel. Can someone tell me how to do the tube for the stinger or will I need to wait for the plans to be available? I was at Oshkosh this year but for...

I didn't want to build a fuselage jig and then burn it so I covered the top with fire resistant sheetrock. I have a nice flat even surface and after making the tack welds I can confirm that this stuff does not burn after the torch is removed. Just remember the taper on the edge when measuring...

AZ Bearhawkers, there is now a Techshop location in Chandler. If anyone does not know what Techshop is, it is a membership based workshop with access to some very useful tools, such as TIG, MIG, OA welding equipment, CNC Plasma cutter, Water Jet cutter, metal lathe, mill, CNC mill. powdercoating...

Hi all, finally getting onboard with the new forum. I am building Bearhawk 535 from plans in Fountain Hills, AZ. I also have Patrol plans #151 and have built all the wing and tail formblocks for that project. I have all of the wing parts for the Bearhawk. I just need to find someone with the...
