I was thinking about this wing jig at work...I'm a machinist...there's no way I could bootleg (aka "G-job") one of these for myself, but I think I could contract to get some batches of the aluuuuminum parts made, if anybody is interested (besides me). You'd have to find your own base. I'll have to get a sketch of the uprights and sliders from Walter or Randy P., then get a price on material and a bid on the machining. Anybody interested?

I have the same jig he uses, but I need the small parts that holds the trailing edge to be bigger. I tried tracking down a guy to make them. No one was making them at the time.
If you could just make the pieces that hold the leading and trailing edge I would love to get a set.

There was a guy on SSW who was suppose to make me one but it hasn't happened yet. So count me in!

Steve,

Sounds like a great idea. I would be interesting in buying a jig, depending on the final price, of course.

In as much as this purchase is only done once, I would be interesting in having the jig done 'first class', with no short cuts, with all details finished as much as practical (with the exception of the base, which would be user supplied). I would have no objection to doing minor jobs like de-burring, etc.

Hi,

Looks like a great idea, with a few different cradles would be universal.
I am very interested.

Paul Taylor · « **Reply #15 on:** September 19, 2006, 02:31:07 PM »

I would also be interested. depending on price. Just like Wynn.

Richard Grogan · « **Reply #16 on:** September 19, 2006, 05:48:21 PM »

Ditto on the price is right condition. Let us know, it looks really nice!

Mike Foley · « **Reply #19 on:** September 19, 2006, 07:13:55 PM »

Most definetely if the price is reasonable

Steve Helmick · « **Reply #20 on:** September 20, 2006, 10:25:08 PM »

I may regret this bright idea. So far, I've got 50 folks saying they're interested if the price is reasonable. Including me...if the price is reasonable. I've got one of our shop buyers looking at the aluminum prices. Drawings will follow that, because "size matters", and it depends on what flange lengths are available. Then bids on machining.

What it boils down to, is how much $$ I am going to invest in jig futures. It seems like the best thing to do would be to keep the batches down to about 10 or 12 units, depending on what will come out of whatever lengths the angle comes in...it could be 10', 12', 20' or 25'. I figured on 2 @20' should yeild 11 sets of uprights (24 per set). It looks like the best LE fitting option would be to copy Randy Powell's system (Tom Morris type). It would be possible to make "V-block" fittings like Walter shows in his P-39 thread, if somebody is insistent. This detail would be relatively expensive to produce.

Steve add me to the list. Ron.

Steve Helmick · « **Reply #22 on:** September 21, 2006, 08:33:09 PM »

It's not gonna happen. Got a price on the aluminum required to make a modest batch of the jig fittings today. It would be over $900 to make a batch of 14. That comes to $60/65 for just the aluminum for one jig, and I expect the machining would be about double that, or more. I don't have that kind of money to put into the project, end of story.

FWIW, I think the best deal going is the Tom Morris setup. Even very nice wood is relatively cheap, and wood parts like his can be buzzed off on a good table saw in a hurry. Sorry to get your hopes up. I can see why the 95th Aero Squadron fella quit making his jigs. Meanwhile, I have a few kits that are designed around rods or tubes for jigging. I suppose I'll have to put up with it.

Thanks for trying!!! The cost/benefil ratio was simply unfavorable. I really enjoy using my Tom Morris "Lincoln Log" jig. But, I do love gadgets!!!
I am glad you explored this option.
Bill

Richard Grogan · « **Reply #24 on:** September 22, 2006, 06:24:05 AM »

Steve,
Definitely not something you'd want to sit in the garage with a hacksaw and do! Thanks for looking into it though. Maybe some manufacturer will see this thread and get the idea to put something like this out there. BTW, appreciate the info on the MACs pipe!Thanks again!
TTYL,
Richard

john e. holliday · « **Reply #25 on:** September 23, 2006, 08:50:24 AM »

Nice try on the jig idea. I think the person over on that other site also stated the same thing about the cost. I need to also ask is Richard Grogan related the Grogens that flew speed and combat back in the 50's & 60's? Later DOC Holliday

Richard Grogan · « **Reply #26 on:** September 23, 2006, 09:28:47 AM »

Hey Doc,

I've read about them and researched it a bit. No relation. I beleive the brains behind their success was with the wheelchair bound guy(Lester Grogan) that did the designs and building.( I forget what the deal was,Polio?) I dont remember who did the flying for him(maybe Larry),IIRC, they were very successful! There was an article in a very old MAN about him, dont recall the date. I beleive they were from Kansas City or St Louis area. My people were from Iowa.

Anyone have a picture or link?

The article I got with the Sweeper kit that Walter made for us stated they were in Misquite, Texas. They had a hobby shop as well as their own flying circle. DOC Holliday

Steve Helmick · « **Reply #29 on:** September 24, 2006, 03:24:01 PM »

I know a Harry Grogan in Florida, from my Free Flight days. I asked if he was related to the Mesquite Grogans, he replied no, but that he did have Grogan relatives in Texas. He is pitting a Fox Racer these days. I'm hoping he'll either get back to FAI FF or fly CL Stunt. Both are very cool...

I actually had relatives in Texas. Pascal Hunter had a ranch between Dallas and Ft. Worth, but was killed in 1836, and his widow and kids moved back to Virginia. How long has it been since there was a ranch between Dallas and Ft. Worth?
