Hi Mitch.I have puchased the plans of the wooden rotor blades from Monty and they are pretty well explained, his discription of these blades when in use is comparing the driving of a Caddie to a sports car. His comment is that the aluminum blades are like a sports car control, small in put for a fast resault where as the wood blades are more doscile. I will be building a set to try over the next 6 months time permitting. Will keep you posted when I start. Des Garvin

Hi Des,Excellent. I have a couple of pics from Monte and the marketing blurb also. Sonny sent me the same stuff Monte sent. Sonny was looking at building a set of Bensons. Monte's are slightly different from the Bensons as I understand it. I liked the wood blades on the glider, probably build a set too at some stage. Have fun Des, keep in touch.Mitch.www.thebutterfly.info

Good mornin MitchFirst let me apologize for taking so long to reply.[:I]A few years back I bought a book from Monty,before the cd.After reading it I went to the lumber yard and got all the wood on the materal list and then to the metel supply and picked up all the metel.Now inthat I didn't know if I realy had the skill to make the blades, I got cheep plywood so I would have plenty of room for mistakes.Actually it turns out it was realy a fast and easy project to compleat.What took the longest time,was the drying time for each glue up,24hr x 3 per blade.Once they were all set it took about 10hr too sand the leading and trailing eadges to shape.Next finish sanding and fiberglass,about 2hrs per blade.When set I balanced the blades in about 2hrs.First making sure they weigh the same,long wise,and cord wise balance and installing the nose weight's was a snap.I think the hardest part was getting the 3deg. twist in the blade bench,and getting the airfoil shape on the nose weights.All in all they turned out pretty good for a first try.Ofcourse I never tryed to fly them becouse of the inferior plywood,so I cant say anything about performance.After that the book got lost in a move and I recently bought the cd.Now having had the chance to see both sets of plans I think Montys will be easyer to build.On the cd there is some vido footage of Monty flying them.He dose go into balance,stringing,and tracking.As of today I havnt done anything toword building another set,but sence I have bought GYRO1 I recon I'd better get of me bum and get going. Now back to the band saw,I use a standup craftsman with a 2hp. motor because I can cut odd shapes and curves,also I can setup a ripfence and rip as long a piece as I wish.I use ether kerosine or bees wax depinding on what I'm doing.I use blades with 32 teeth per inch,14 to 12 inch wide. Well I hope this helps,if you have any questions,or advise I would greatly appriciate and try to answear.As far as I know There is knowone within 100mi.that even knows what a gyro is,so I rely greatly on the info that comes from the forums,here and the Rotory. Regasds Sonny

A salient point with using lubrication on saw blades...The cut will have traces of Lube on it. If a bonded joint is to be made on the cut face, the lube will affect it badly, thorough cleaning is required or the surface reworked to remove the lube.

Sonny,Great info Buddy. I think Des will appreciate this as well. I too am somewhat isolated by distance and a stretch of ocean from the main players, living in Tasmania an Island State of Oz. Tell James we have no pet Roo. BUT we (Aussies) all have had close contact with them at one time or another. Great to hold a little Joey and then watch him slip back into Mum's pouch. Many Aussies do have pet Roos though as well as other Native animals, ie snakes, dingoes and even Tassie Devils. Remember Taz from the classic Disney Cartoons.I got your email about why men and women have two hands, but the pics didn't come through and I could not open them, so I am still waiting for the 'punch line'. Thanks Sonny. Best regards to Barbara and all the family. I am comming to PRA Convention and OshKosh this year, any chance of catching up?Mitch.Hi Nick,Sorry no further develpoment in that yet, still trying to get into the air, which means co-ordinating the weather, instructors days off and then my availability given the 'Missus' works 4 on/4 off, then I have the two young kids to juggle. It's all a bit frustrating at this time.Mitch.www.thebutterfly.info

Hi Sonnyj, Thanks for the interesting comment you made regards the making of Monty's blades. I only have one question about when you were sanding the leading edge profile what type of belt sander did you use. I thank you in advance for you comments. Des Garvin

Hiya DesIt was a 3x21 handheld Rockwell belt sander,I picked it up in a pawn shop for realy cheep.When sanding any part of the blade,I found that walking up and down the leangth of the blade,produced a very uniform and smooth finish.I used 2 different grits of belts the first one was course too get a ruff,then a lite to medium grit to finish,then by hand a very lite grit before applying the fiberglass.I hope this helps.Regards Sonny

Mark,You read my comments, did not see me saying anything about it being noisy, "a little humour, not to be taken seriously", it's not so much the disc thats is noisy it's the dropsaw, when you have finished cutting just listen to the noise the drop saw makes on wind down when not cutting, it is expected that there will have to be some noise when cutting anything, accept a hot knife through butter for example, as Des said don't forget to "butter" both sides of the blade, and frequently.However Mark I fully agree with you, I find the noise offensive and worry what my neighbours think, all the best.Pete Barsden
